State Information Center: 2009 cold, the inverter air conditioner made a breakthrough development, market share rose from less than 7% the previous 18%. In 2009, the first 11 months of cold

Sell In the United States and the frequency to 27% market share, the highest in the industry first.

In Yee Monitoring Report: 2009 in the first half, inverter air conditioner sales by leaps and bounds, cover 75% of the frequency of domestic market share. America’s top ten best-selling variable frequency inverter air conditioner models occupy the top three, with 23.95% market share, retaining its position as the industry first.

Cold in just the past 2009 years, the domestic air conditioner industry to take advantage of national policies “east” rapid growth, especially in inverter air conditioner, won the unlimited scenery.

America’s Inverter Air Conditioner

As an industry leader, is also undoubtedly boarded the “frequency King” throne. According to the State Information Center and research institutions in the PRC, the report shows that the overwhelming advantage the United States in the conversion of a retaining its position as the industry first. Frequency from the unknown to do, to success, “Frequency king” status, in just one year, the United States and the inverter air conditioner is to mold “the legend of the United States?” Below, we Yiyi for everyone Jiemi U.S. success “Tips.”

First one: no “step by step”

In fact, the inverter air conditioner to enter the Chinese market has for decades, but why have there been in the “praised in” the embarrassing situation, mainly trapped in the lack of core technology, which directly caused the inverter air conditioner made a huge loss of profits and products serious homogenization. However, the core technology for the processing, domestic appliances business easily into the “blind worship” and “blind fear” the two extremes. Reaction to the product, or super-expensive super-high-end, or is a fake fake conversion technology, nature will not win the favor of consumers.

As one of the domestic air-conditioning giant

U.S. air-conditioning back in 1992 began its own study frequency conversion technology. After decades of frequency conversion technology accumulation, and finally found a domestic market development path?? “Leapfrog development path”, that is, skip the AC variable frequency, square wave frequency of 120 degrees several technical level, the direct development of the core technology products?? sine wave DC inverter 180 degrees.

Proved that when the U.S. launched air-conditioning in the domestic popularity of DC inverter air conditioner when the storm, most competitive products still in the AC frequency and the square-wave frequency conversion stage. “Survival of the fittest, survival of the fittest,” AC variable frequency and variable frequency square wave “forced” to quit the stage of history. 180 degree sine wave technique for the development of the United States Wu, vice president of new air-conditioning that, for businesses and consumers, the best technology is not necessarily the most appropriate; only the most suitable is the best.

Second type: not “behind closed doors”

The saying goes, “good things to share with friends.” In the rest of the world today, how variable frequency technology for the global sharing, the United States air-conditioning in the conversion on the road to do two pen “big business”, that in 2004 “marriage” Toshiba Carrier and 2008, together 12 world-class global frequency components signed a 2.5 million sets of suppliers purchase a large single.

2004 6 3, Toshiba Carrier with the United States held in Beijing, “International Wedding”, the two sides formally signed a general agreement: the United States joint venture with Toshiba Carrier 300 million yuan, in

Shunde Built a capacity of 300 million compressor production base, the United States holding 60%; Toshiba Carrier 40% shareholding. Core components to achieve the inverter air conditioner?? Frequency localized production of compressors, inverter air conditioner in the United States on the development process, which is a landmark event. Wu, vice president of the United States a new air-conditioning says.

2008 12 9, the U.S. president, Greater China IR FredLi,

Matsushita Motors Chen-Yu, General Manager Matsuura,

Sanyo

Ozawa, vice president of the compressor and so clear the frequency of 12 world-class supplier to shoot straight giants gathered at the U.S. headquarters building air-conditioning, Shunde, and the U.S. signed a 2.5 million sets of air-conditioning components and large unit inverter air conditioner purchase agreement. Such high-level providers, such large purchases,

China’s largest air conditioner production base of green fluorine-free environment and China’s largest export base — Air Conditioning Electric Industrial Park, Zhongshan, Shenzhen Bao in the Pearl River Delta, Zhongshan City, declared completed. The industrial park covers an area of more than 500 acres, 300 million dollar investment, the annual production capacity of 3 million sets of air-conditioning. Together with the industrial park highlights the people in front of the Chinese home appliance industry legend Deng meters high. When years of professional managers, why Nianyuhuajia Deng m high to today’s management team would also like to pull up once again into the field of household appliances? Why should it seem to be more brutal competitive environment in 2003 chose to enter air-conditioning industry? Reporter tried to solve this mystery.

Has been circulated in the household appliance industry emerged six million units last year, air-conditioning inventory information has been confirmed. According to preliminary estimates, in 2002 the amount of China’s air-conditioning products in stock up to 110 billion, stock prices decline as much as 1.93 billion loss. Air-conditioning manufacturers high inventory of all cash flow is bound to tighten the chain, some companies due to inventory tying up capital, a direct impact on the development of new products this year, and the air-conditioning market. For repatriating their capital, a small number of air-conditioning manufacturers have already begun ahead of schedule in order to engage in promotional activities in the form of slightly lower prices. As the inventory is too large a number of air-conditioning companies today have no funds for new research and development, many enterprises have not so far in this year’s new products, the situation very difficult. No new product is not available at a competitive advantage, market position, will be very passive.

The one hand, raw material prices, the other hand, the intensity of market competition, not weakened, air conditioner market this year, there is indeed a good show to watch. The “deep treasure” air-conditioned environment is in such a decline in health.

Zhongshan, Shenzhen Bao Electrical Appliance Manufacturing Co., Ltd. Deputy General Manager, China Jianhua, general manager of marketing analysis corporation “deep treasure” of the market environment facing, said the final analysis, this is the air-conditioning industry faces the challenges of the market and consumers, the National 6 million sets of air-conditioning inventory, production capacity 30 million sets, as well as smoke-like “shuffling” argument, as well as not tell Tao unknown “price war”, these problems show? Shows that China’s economic wave-shaped micro-and macro-control imbalances reflect and air-conditioning market anomalies and irregularities. Because the air conditioner market are not standardized, a lot of fake and shoddy products, brands vary greatly, and the price war a dozen, these problems become more prominent, and very conducive to the formation of consumer confidence to consumers.

Tang Kin-wah said that “deep treasure” at this time born, both facing the pressures and challenges, but more full of hope, home air conditioners in the city where the current penetration rate of less than 40%, but with the Habitat condition improvement and construction The expansion and is still in the “virgin land” of the township market, will form a huge market potential and market capacity, at present there is no real air conditioner market leading brands and monopoly brand in China’s competitive environment, are also unlikely to have the leading brands and monopoly brand , which gives “deep treasure” so that the new brand into a strong left a huge market space. The core of the current air-conditioning market competition is a comprehensive change management, marketing level, scientific and technological level, product level, personnel structure, and capital capacity. Objectively speaking, no matter where on the one hand, the “deep treasure” possess competitive advantages in these areas.

“Characteristics” build confidence in the

DENG Jian-hua believes that now air-conditioning industry, competition has become more and more intense, a number of first-line brands have been exhausted to the time, while some second-tier brands Seeing barely, and compressors, steel and other accessories are all up sharply price, small factories naturally no way out. If the newly added brands continue to be used in the past approach to development, also believes that the gap can be used to obtain the market room for maneuver, it may be wrong.

In the current environment, “deep treasure” in the industry want to splitting a piece of cake to find their own survival and development of space, out of a glorious road, Jianhua that, it must be a strong entry, one should be a high starting point, second, a high level of This is strong. Otherwise not do it, do we will certainly do the best. To find the point of market demand and industrial development direction of industrial development before strangling the throat of others and making it “deep treasure” brand merchants, features and deep features. This can be invincible.

Jianhua details of the “deep treasure” air-conditioning series two advantages: First, the green environmental protection series of fluorine-free air-conditioning, two highly efficient cooling and heating air-conditioning series.

Approved, the current consumption of China’s environmental protection fund has been established, the Foundation has injected 10 million yuan, is a deep treasure of international fluorine-free air-conditioning consumption, environmental protection special fund is mainly used in the Chinese market for environmentally friendly air-conditioning consumption behavior of the reward, according to environmental and consumer Fund was established to create a powerful social forces, to advocate protection of the environment, love life, protect the earth. Process is deep Bowes to provide a new environmentally friendly R407C and R410A advanced air-conditioning refrigerant to replace the freon environmental products in the Chinese market, consumers purchase and use behavior that is contributing to the protection of the environment.

Turning to exports, while Tang, Executive Director Michael said that the Pearl River Delta became increasingly evident, including cooling, including the international home appliance industry, manufacturing center, and he has done a lot of home appliances in the international old customers, contacts in all these years already have a deep understanding of and the establishment of a deep friendship, both in Italy or Singapore, both in Turkey or the Middle East and in Europe, North America, South America, “deep treasure” can receive the full support of a lot of old friends, priority orders. In the “deep Po Industrial Park” is not constructed, “deep treasure” on the adoption of OEM exported more than 80,000 sets of air-conditioning. Now he is considered the most is how to make the next batch after batch of orders for high-standard export tasks to complete to make word of mouth, to facilitate “deep treasure” in the international market more competitive, so he revised this year internal export ratio requirement for export 200 thousand sets, 100,000 sets of domestic sales, reducing the proportion of the domestic market, focusing on the international market.

Changhong burdens

One and a half months later, Sichuan Changhong Electric Co., Ltd. (Sichuan Changhong, 600839.SH) announced the sale of its air assets, related to the program.

November 10, Sichuan Province and Investment Property Exchange Center hung out the deal: by the Sichuan Changhong commission, trading center to transfer its holdings of publicly listed Sichuan Changhong Air Conditioning Co., Ltd. (hereinafter referred to as “Changhong air-conditioning”) 100% equity interest ( with the transferor directly held 99% of the equity and the transferor owned subsidiary of Sichuan Changhong Innovation Investment Co., Ltd. holds 1% stake), and Zhongshan Changhong Electric Co., Ltd. (hereinafter referred to as “Zhongshan Changhong”) 90% stake.

Guapai Jia for the transfer of 393.06 million yuan.

The news came out, the industry generally optimistic about the transfer of Sichuan Changhong, one resolved itself with owned subsidiary of Hefei Meiling Co., Ltd. (hereinafter referred to as Meiling Electrical 000521.SZ) in the refrigeration business, intra-industry competition issues; second is through this pile transaction, Changhong removable re-forward.

Changhong’s air-conditioning categories of assets up for sale by Sichuan Changhong news announcement, the market price immediately on the Changhong with warm response – November 12, Sichuan Changhong and Meiling Electrical Appliances both daily limit, closing down more than one-million contracts.

As early as Day before the September 23, Sichuan Changhong board meeting, announced a restructuring program.

That Changhong for strategic development needs, in order to circumvent with the white-owned subsidiary Meiling Electrical power industry of the potential existence of intra-industry competition, acquisition of Hefei Meiling Co., Ltd. to fulfill the commitments made when agreed to the state-owned asset management company under the relevant provisions of Stock Exchange means the transfer of property rights held by Changhong to sell 100% stake in air-conditioned and Zhongshan Changhong 90% stake.

Self-selling self-purchase?

Sichuan Changhong air conditioner for the sale of assets, the industry is more inclined to this is a “self-sell from buy” over-market transactions, that is, Changhong air assets for the ultimate pick set by Meiling Electrical Appliances.

For the industry to this speculation, this paper a number of contacts, Head of Asset Management Changhong Yang Jun unsuccessful.

Now it seems that Changhong air conditioner in the market is also a good reputation in recent years, companies have spent great efforts to the market has done a lot of input, such as Changhong air conditioner in 2007 by World Brand Lab (WBL) as TOP of the Year Award, In the “market share”, “brand loyalty” and so on several indicators assessed on the forefront.

But this is not quite commensurate with the financial statements. Sichuan Changhong, according to the disclosure notice, Changhong air conditioner first half of 2009 operating income of nearly 7 billion, but net profit of only 3.6 million yuan, Changhong air conditioner’s operating profit margin in the first half of 2009, even 1% were not met.

From this point of view alone, Changhong air conditioner has become an asset class as a whole Changhong Sichuan Changhong Group’s “tasteless” – tasteless but wasteful to discard, but it is also precisely constitutes a unit of Meiling Electrical Appliance competitive relationship with the industry. Changhong eventually led to it being “dismembered” fate.

Reanalysis Zhongshan Changhong’s asset structure, the first half of 2009 operating income of 1.46 billion yuan, net profit of 2.52 million yuan. Zhongshan Changhong targeted at overseas markets, the profit performance of this plate is still not well, Sichuan Changhong right Zhongshan Changhong holding 90% stake, while 10% owned by China Minmetals Group.

However, the new problems have cropped up, Sichuan Changhong air conditioner sale of assets, really, as the current analysis of the industry “self-sell from buy” do? To reporters when the deadline, Changhong there is no person came forward to respond to this market rumors.

In the property rights trading center, Changhong indeed bidder proposed a “harsh” demands: for example, the transferee a registered capital of not less than 4 billion yuan; transferee to set up more than three years, 2007,2008 profitable years in a row; transferee side can only be purchased separately, does not allow joint purchasing; transferee after the signing of the contract of assignment of property rights may not be transferred within five years the subject of the present assignee.

In addition, the transferee must promise: in this equity transfer is completed, maintain the air-conditioning and Zhongshan Changhong Changhong main business stability, and registration and tax payment to the same; to maintain the air-conditioning and Zhongshan Changhong Changhong management and staff of the basically stable, according to relevant provisions of the continued employment of the target enterprise’s employees.

Based on analysis of many media, Changhong air conditioner next set of assets, non-Meiling none other than electrical, but insiders said Changhong, Changhong air assets, the transfer of listing, but also to be a state-owned assets management of the relevant provisions.

Some people question the authenticity of Changhong’s asset-related assessments, such as in the first half sales revenue of 7 billion Changhong air-conditioning, its net profit 3.6 million yuan is really only a few do?

Meiling took over the air-conditioning and Zhongshan Changhong Changhong, no doubt in full compliance with all the conditions put forward by Changhong, including maintaining the stability of staff and management, as Meiling itself is a holding subsidiary of Changhong, in accordance with such a low price, no doubt picked a landing peach.

Meiling Electrical Appliances for air-conditioning business and competition issues in the same industry, Sichuan Changhong three-quarter earnings report, and has been described as follows: “In order to avoid intra-industry competition, as long as the company continues to Meiling shares of controlling shareholders or substantial control of people, the companies have agreed to In the interests of the Company and the Meiling shares the interests of all shareholders circumstances, shares of the company and Meiling integration of related businesses. If the company Once you have the opportunity to engage in competitive business and will share the prior written consultation with Meiling is willing to engage in competitive business … … Meiling shares only when confirmed or deemed to not engage in competitive business, the Company will engage in the same industry do not have the competitive nature of business. “

The transfer by agreement or open bidding, Changhong, at least from the transfer of the two companies to obtain at least 4 billion in cash, which in the plasma that had been invested heavily in projects in Sichuan Changhong, no doubt, is a valuable flow of funds. In order to raise funds for the continued development of enterprises, this long ago, Sichuan Changhong has just issued a 30 billion yuan in convertible bonds separate transactions.

However, dealing with air-conditioning assets, to lay down the burden of Sichuan Changhong still face another similar problem, that is, before the acquisition of Huayi Compressor Co., Ltd., with Meiling Electric still exists a wide range of competitive relationship within the same industry.

Bharatbook.com added a new report on “China Car Air-conditioning Industry Report, 2009″ which gives the growth and market trends of China Car Air-conditioning Industry.

China Car Air-conditioning Industry Report, 2009

The car air-conditioning system mainly consists of compressor, condenser, evaporator and air heater, wherein, compressor is the heart, thus the status quo of compressor market directly relates with the development prospect of car air conditioning industry. ( http://www.bharatbook.com/detail.asp?id=129786&rt=China-Car-Air-conditioning-Industry-Report-2009.html )

Chinese car air-conditioning compressor market kept fast growth from 2003, and the total output reached about 8 million sets in 2008, up 24.42% yr-on-yr, the total sales amounted to 7.27 million sets, up 13.95% yr-on-yr. In 2008, the output of foreign-funded enterprises was 6.27 million sets, accounting for 76.7% of total output of passenger car compressor. OEM market is mostly monopolized by foreign-funded enterprises, and the industry competition becomes increasingly fierce. From 2001 to 2005, the price dropped from RMB1,200/set to RMB800/set, and from 2005 to 2009, the price decreased by 7.5-9.5% annually on average. Furthermore, Chinese enterprises are relatively lagged behind in research and development, which causes the Chinese products mainly to flow to after-sales markets in China and abroad.

The manufacturers of car air conditioner and air-conditioning compressor comes primarily from Japan, the USA and Germany, such as Denso, Shanghai Sanden Behr Automotive Air Conditioning Co., Ltd, Zexel and DELPHI, which all have wholly-owned subsidiaries or joint ventures in China to put on production. Among them, Japanese manufacturers take the largest output. In addition, Chongqing Jianshe Automobile A/C Co., Ltd., and Mudanjiang Car Conditioning Compressor Company also take some certain market share.

In 2007 the world economy has maintained solid growth. Some of the major developing countries have also continued stronger growth momentum. For example, China’s GDP growth rate of 11.5%. China, Brazil, Russia, and India’s economic growth contributed to the entire world economy forward. 2008 Beijing Olympic Games and 2010 Shanghai World Expo and other activities to stimulate the demand for air conditioning and refrigeration products is rising rapidly. Accordingly, an integral part of the air-conditioning industry – compressors also gone through another growth year.

2007 World HVAC total market value of about 100 billion U.S. dollars, half of which is the air-conditioning products, and the remaining half of refrigeration products. In 2007 the world’s air conditioner market in total sales for the 74 million units, compared with 70 million units in 2006, an increase of 5.1%.

China first in the world occupy the air-conditioning sales, the market scale reached 23.2 million units. In 2007, including the brand around the world, including about 30 million air conditioners from China’s exports, compared with 2006, an increase of 13.5%. Chinese production of air conditioners accounted for the entire world air conditioning market, 72%. China is not only in aircraft products, the biggest supplier of the key components.

China’s current production of rotary compressor is about 80 million units, and every year is growing. China’s motor, heat exchangers, controllers and plastic production is also walking in the world.

In the United States in 2007 sold 780 million units of air-conditioning, of which 710 million is a room air conditioner (almost all of the room air-conditioners are wall-style), 70 million units is a cabinet air conditioner, while the window-type air conditioner The number accounts for only 2%. Most of the heat pump is a variable frequency drive, and all the room air-conditioners and most of the cabinet air conditioner uses R410A refrigerant.

Europe’s sales growth in air-conditioning made great contributions. Sold in Europe in 2007 a total of 8.4 million air-conditioning units, compared with 2006, an increase of 13.5%. Russia’s air-conditioning sales in 2007 increased by 27.1%, increase is the highest in Europe.

In addition to China and Japan, other Asian countries the growth in sales of air conditioning has also played an important role. In 2007 sold the air-conditioning in these countries there are 9.7 million units, compared with 2006, an increase of 12.1%.

In 2007, raw materials prices continue to rise sharply, resulting in an increase in production costs. To this end, manufacturers concentrate on looking for ways to reduce consumption of raw materials, to remain competitive.

CO2 System: Compressor Highlights

According to BSRIA / JARN study, in 2007 the total value of the global compressor market of 211 million. Among them, reciprocating compressor market is about 11.9 billion U.S. dollars, rotary compressor market is about 4.9 billion U.S. dollars, scroll compressor market for 3.4 billion U.S. dollars, screw-type compressor market, 700 million U.S. dollars, centrifugal compressor market, about 2 billion U.S. dollars.

Energy-saving and environmental protection are the two main themes of compressor industry.

    Starting in 2010, HCFCs produced in the United States will not be allowed to use new equipment. This case, the application of environment-friendly refrigerants has been the HVAC and refrigeration industry hot topic. In recent years, the most pressing in this area is to develop the theme of CO2 compressor. CO2 can be used in automotive air-conditioning compressor. Vehicle air-conditioning is cross-Zero CO2 cooling one of the most important fields of application. Japan, U.S. and European research institutes and manufacturers in this regard is very positive. European companies such as Danfoss, and Bock has been developed out of the bus with the CO2 air-conditioning compressor. Japanese companies such as Denso, has begun to small batch production of this product. Shanghai Jiao Tong University in cooperation with some companies, the development of the CO2 car air conditioning compressors.

Heat pump water heater (HPWH) is another application of a CO2 compressor area. One advantage of CO2 heat pump water heater can heat water to 90 degrees Celsius, while the ordinary traditional refrigerant heat pump water heater system in the same cases only the water heated to 55 ℃. In addition, CO2 heat pump water heater COP values of up to 4.9.

CO2 heat pump water heaters in Japan, has developed rapidly. Of 2005, including Sanyo, Daikin, Hitachi, Toshiba, Carrier, Melco and Panasonic, including nine Japanese company was jointly developed by ECO CUTE series of CO2 heat pump water heater shipments of 210,000 units. In 2008, shipments will reach 35 million units.

Sanyo CO2 in the rotary compressor R & D done very well. Their products to achieve high efficiency, low noise, low vibration and high tolerance. In addition, these products are two compression mechanisms, and internal medium pressure system, able to withstand high-pressure CO2. Sanyo also speed the commercialization of CO2 compressor for 900W ~ 2200W series of domestic heat pump water heater. Recently, Sanyo 400W and 500W output power, single-speed cooling system and the 500W output power transmission system has also been commercialized. Now, Sanyo is to enhance the safety of its products for use in a variety of devices (such as commercial refrigerators, freezers and vending machines, etc.). Denso, Daikin, Panasonic, Melco and Hitachi have developed their own CO2 compressor for heat pump water heater products.

Dorin has developed the world’s first semi-closed pressure reciprocating CO2 compressor. This compressor can be used in HPWH and light, medium-sized commercial refrigeration equipment. Power range from 0.75kW to 15kW motor capable of medium-speed and high-speed mode operation (1450rpm and 2900rpm). Compressors ranging in diameter from 18mm to 34mm.

Refrigerants: HFCs facing a turning point

In recent years, HVAC air conditioning and refrigeration industry, many manufacturers use HFCs refrigerants (R134a/R410A/R407C, etc.). Many air-conditioning with R410A, coolers using R134a, refrigeration equipment using R404A, it seems a foregone conclusion. However, these refrigerants high potential greenhouse effect, while HFCs are not ozone-depleting substances (ODS). Accordingly, the natural working fluid (such as CO2, NH2 and HCs) research and commercial trials are underway. For household air conditioners, the hydrocarbon R600a has been commercialized. Even if the United States from R22 (HCFC) refrigerants HFCs shift the footsteps behind people, but the new products from 2010 prohibiting the use of HCFC’s bill has been passed, a lot of air-conditioning manufacturers intent to turn R410A. Some industry insiders believe, R410A in the next few years, dominating the world market, most of the refrigerant Jiangshan. R410A products will use energy-saving costs, environmental protection and energy saving have a great advantage.

    Therefore, many European compressor plant proposed the use of CO2 compressors developed and applied to the mobile air-conditioning on. Although CO2 is to promote global warming gas, conventional refrigerants, but the global warming caused by the same amount of CO2 than the global warming caused by the high 1400. Moreover, the air conditioner out of a small amount of CO2 released from power plants and vehicles with a large number of CO2 emissions is negligible in comparison. For small and light systems such as car air-conditioning and mobile air-conditioning is, CO2 system, great development prospects.

But the CO2 system, a major drawback is that they must be under the pressure of a large operation (5 times higher than traditional systems), operating under high pressure caused a certain degree of engineering challenges, and requires use of heavy pipe. However, in recent years, manufacturing processes and other technical advances that have helped to increase the feasibility of application of CO2 systems.

However, in areas of relatively high temperature, CO2 as an air-conditioner refrigerant efficiency is not high. Moreover, due to the need of high strength to withstand pressure, the compressor or chiller systems are cumbersome, the implementation of mobile air-conditioning is also difficult. Two large chemical companies Honeywell and DuPont launched a new low GWP value of HFCs refrigerants (R1234yf) Development. The completion of toxicity testing will take a long time. Despite the development of new refrigerant ultimate success are uncertain, but the car makers are already inclined to use CO2.

Lubricants: alternative technologies by the attention

Since all firms are faced with air-conditioning to reduce costs and improve efficiency of the pressure, the choice of lubricants for the overall efficiency of refrigeration and air-conditioning compressor efficiency is vital, so that vendors feel the need to replace the current use of lubricant. In recent years, the main difficulty is the development of lubricants HFCs and natural refrigerants lubrication unit reliability.

Automobile manufacturers to develop the polyether (PAG) CO2 compressor has become the trend. Japan’s Idemitsu Kosan (Idemitsu)’s transformation after the PAG has been applied to the CO2 heat pump water heaters on all of Japan. As a leading manufacturer, Idemitsu is a mature technology provides support for its plant located in Tianjin, China, well-run, the supply of lubricants for many compressor manufacturers.

Automobile air conditioners are not given much thought during those cooler months of the year, but as soon as the weather begins to warm the air conditioning questions start up. There is no one category of problems or concerns when it comes to air conditioners.

Owners want to know how to control odors or eliminate them altogether, how to make the air conditioners blow faster and harder or they have questions about unusual sounds or noises that they are hearing when they turn their systems on. Other owners are most annoyed over what they describe as too little coolness being produced by their once well functioning AC systems. Troubleshooting AC units is one of the most common tasks that is requested by automobile owners today.

The coolant that is used in automotive systems today is R134a. This substance is formulated from microscopically tiny particles. Its tiny size means that it can escape, or leak, from any type of opening that occurs within the entire cooling system. If there are leaks this means that there is less available coolant and this is one of the reasons that owners suddenly notice the drastic decrease in the ability of their air conditioning unit to produce the type of coolness that they are used to.

This was a much more common problem in the past, but with the introduction of the new coolant, the seals and hoses being used were also upgraded to help ward off this type of situation. There is no fool proof way of keeping the system completely tight and leak free and over the course of time there will often be enough of a loss of coolant to produce problems. Once the coolant level has dropped far enough the lack of cool air conditioning will be readily apparent. It usually requires 3 or more years for slow depletion of the coolant to reach this level.

With the newer types of air conditioning systems there have been changes in the design which means that they will not blow out the amount of air that owners may have seen with older model cars. These air conditioning systems are designed to be lightweight and efficient.

The aim is to cool the vehicle to a particular level and provide no additional cooling. This different cooling system is often problematic for some consumers to understand. They want the temperature level to drop fast and at a furious rate when they engage the air conditioners. This is not quite the way today’s AC units are designed to work for us.

Instead of carrying a couple of kilograms of cooling material, most of these units only have a scant half kilogram contained in their system. This means that while cooling is possible, it will not be instant frosty cold breezes that chill everyone in both the front and the back seats. Today the air conditioners are much more efficient and environmentally friendly.

The air conditioning systems used in autos today are designed to get good amounts of cooling out of smaller units but this makes any loss of coolant readily noticeable. With a leak in today’s systems, there is no way the air conditioner is going to be able to properly cool the car.

A quick recharge of the coolant is usually all that it will take to have the AC working once again. Mechanics will also need to do a system test to see if there are any other pinhole leaks or loose seals before he will recharge the system. This will prevent damage to the environment and will save the auto owner money in the long run.

When it comes to the strange noises that may be encountered when you turn the air conditioning on, there could be several reasons that this is happening. Sometimes tiny bits of gravel or road debris can become trapped in the ridging of belts and this could be what you are hearing. This can prove easy enough to check and remedy. An AC unit that is overcharged with coolant can create a hydraulic lock in the compressor machinery. This will create a loud thump, or hammer sound.

Too little coolant can create bearing failure and this will create a knocking sound whenever the compressor is engaged. The compressor can easily be damaged if there is a major leak in the system and the owner is still trying to use the AC. This will create a loud knocking sound that is unmistakable to a mechanic.

Air conditioning problems can also be due to faulty switches or fuses. The vent doors inside the AC housing can also become stuck, and even pens, papers, clips or other bits can find their way into the defroster vents and manually block the doors and prevent cool air from entering. Sometimes the housing unit will have to be removed for cleaning and repair. Always keep vents in your car free and clear of anything that could slip through the openings and create problems.

For bad odors from air conditioners, be aware that mold is usually the responsible culprit. There are sprays you can purchase to use to help with this problem. You can also take the car to an auto shop where mechanics are trained to deal with problems of this type. One suggestion that may help is for you to always try to run the air conditioner for a few minutes before you park the car for the night. This may help dry the vents which can decrease the damp environment that is necessary for mold to thrive.
