By zoning if the compressor can be divided into space air conditioner compressor on, modular air conditioning on the compressor, refrigerator compressor on the compressor and other uses broad categories. Beneath our primary and combined from the room air conditioner compressors both speak about the trend of globe development.
A space air conditioner 2002 the global production of about 34.03 million units area air conditioner compressor.
In the field, the development of the compressor can be summarized as the following:
1, the production focus to China and East Asian countries
To additional lessen the price tag, the main air conditioning manufacturers are much more production to low labor costs in China and East Asia. The manufacturer plans to output scroll or rotary compressor installed in the local production of air-conditioning, such as Panasonic is prepared in its Guangzhou plant R410A DC scroll compressor, and install them to the neighborhood production of air conditioners device on, and then they sell to the Japanese. Matsushita will also sell to local competitors in the compressor to create space air conditioners.
two, refrigerant transition to HFC In Japan, has a lot more than 95% of the refrigerant has been converted to R410A, but in China and East Asian countries, R22 refrigerant is still the only resolution seems to the globe. Nevertheless, the R410A transformation is beneath way, 5 years later, R410A refrigerant share will improve to 25%.
three, EER higher, accelerating the development of frequency manage
In Japan, to meet the “energy saving law revision” of the needs of power-saving competition is intensifying. Thus, as shown in Table 1, the major manufacturers of two.8KW models of cooling / heating typical power efficiency ratio reached five.89-6.01. The use of space air conditioner compressor is rotating, swing or scroll. The space air conditioner has been upgraded to high-end models, use R410A refrigerant, variable frequency control and efficient DC motor. In order to avoid international warming, international energy guide is very essential. China is ready to join the WTO as a turning point, the energy requirement in law.
Guangdong Meizhi Compressor Co., Ltd. Mr. K. Kumashiro estimate: By 2005, China’s space air conditioners, the DC inverter compressor ratio would rise to 30%.
1981, the first frequency control variable speed rotary compressor used for the very first time in the area air conditioner on. This compressor has greatly improved the energy saving, increased comfort and accelerated the speed of heat the room air conditioner.
A kind of twin rotary compressor (rotary piston) in 1985 for the very first time in Japan, employed in a commercial air-conditioning on. As the enhanced vibration characteristics, which for large rotary compressor, thereby paving the road. 1988, applied to the inverter control area air cylinder rotary compressor come out, to expand its range of low-speed operation, so that power range to far more than double than the earlier model. Thus, to attain a further energy saving, lowering vibration and noise levels, improve room comfort.
4, the most recent study outcomes Matsushita Electric Corporation in 2002 Purdue Compressor Technologies Conference, announced a carbon dioxide brushless DC motor compressor (see Figure 1) study results, the displacement is 4cc. Matsushita also said that by adjusting the fuel injection rate, carbon dioxide, power efficiency compressor with R410A scroll compression
Machine quite. Italy Ddlonghi also introduced three types of models of two-3.6KW of split type, use the R290
