Reconcile the refrigeration market: to promote industrial development.
2007 to maintain solid growth in the world economy. Some major developing countries also continued stronger growth momentum. For example, China's GDP growth rate of 11.5%.
China,glue stick Brazil, Russia and India to promote economic growth throughout the world economy forward. 2008 Beijing Olympic Games and 2010 Shanghai World Expo and other activities to stimulate demand for air conditioning and refrigeration products,glue gun the rapid rise. Accordingly, an integral part of the air conditioning industry - the compressor has gone through another growth year.
2007 World HVAC total market value of about 100 billion U.S. dollars, half of which is air-conditioning products, and the remaining half of refrigeration products. The world's air conditioner market in 2007, total sales for the 74 million units, compared with 7,000 million in 2006 increased by 5.1%.
Air-conditioning sales in China accounted for first in the world, the market scale will reach 23.2 million units. 2007, including the brand around the world, including about 30 million air conditioners from China's exports, compared with 13.5% growth in 2006. China accounted for the production of air conditioning market in the world 72%. Products not only in the whole of China, the biggest supplier of the key components.
China's output of rotary compressors about 8,000 million units, and growing every year. China's motor, heat exchangers, controllers, and volume production of plastic to go in the world.
In the U.S., air-conditioning in 2007 sold 780 million units, of which 710 million is a room air conditioner (almost all the rooms are wall mounted air conditioners), 70 million is the cabinet air conditioner, the window air conditioner the number of only 2%. Most of the heat pump is a variable frequency drive, and most of all room air conditioners and air conditioner using R410A refrigerant tank.
European sales growth for the air conditioning a significant contribution. Air-conditioning in Europe in 2007 sold a total of 8.4 million units, compared with 13.5% growth in 2006. 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, sales growth in air conditioning also play an important role. 2007 sold in these countries there are 9.7 million air-conditioning units, compared with 12.1% growth in 2006.
In 2007, raw materials prices continue to rise sharply, resulting in increased product cost. To this end, manufacturers concentrate on finding 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, the reciprocating compressor market is about 11.9 billion U.S. dollars, rotary compressor market for about 49 billion U.S. dollars, scroll compressor market is 34 billion U.S. dollars, screw compressor market $ 700,000,000, centrifugal compressor market about 2 billion U.S. dollars.
Energy saving and environmental protection are the two themes of the compressor industry. The Government of Japan provides heating and cooling equipment, the value of the average COP, also released the Japanese version of the RoHS (electrical and electronic products on the Restriction of the Use of Certain Hazardous Substances Directive). All room air conditioners sold in Japan are using R410A refrigerant. Japanese companies in the development of highly efficient DC inverter compressor technology, walking in the forefront of the world. WEEE EU published Directive (Directive on Waste Electrical and Electronic Equipment) and RoHS directives. EPA developed a new manufacturing standards, and in January 2006 entered into force. This standard requires less than 65,000 Btu / h of room air must meet the seasonal energy efficiency ratio (SEER) 13 or higher value. Starting in 2010, HCFCs will not allow the production of new equipment in the United States to use.
In this case, the application of environmentally friendly refrigerants has been the HVAC and refrigeration industry hot topic. In recent years, the most urgent in this area is to develop the theme of CO2 compressor. CO2 can be used in vehicle air conditioning compressor. Automotive air conditioning refrigerant CO2 across the zero bound one of the most important applications. Japan, U.S. and European research institutes and manufacturers in this regard is very positive. European companies such as Danfoss and Bock have developed the CO2 out of the bus with air-conditioning compressor. Japanese companies such as Denso will begin small batch production of this product. Shanghai Jiaotong University, also with a number of companies, development of CO2 car air conditioning compressors.
Heat pump water heater (HPWH) is another piece of the application of CO2 compressor field. One advantage of CO2 heat pump water heater can heat water to 90 degrees Celsius, and the tradition of using common refrigerant heat pump water heater system in the same circumstances only the water heated to 55 ℃. In addition, CO2 heat pump water heater COP values of up to 4.9.
