In 2002, global production of 34030000 room air compressor about Taiwan.

In this field, the development situation of compressor can be summed up in the following:

1, production to China and east Asian countries

In order to further reduce the price, the main air-conditioning manufacturers will produce more cheap labor costs to the China and east Asian countries. These factories plan will produce scroll type or rotary compressor installation of air-conditioning equipment in local, such as matsushita to guangzhou factories in the scroll compressor and R410A dc they mounted to the local production, the room air to Japan will they sell. While panasonic will also compressor sold to local rivals to produce room air.

2, the refrigerant to HFC transformation

In Japan, has more than 95% of refrigerant, but have to R410A in China and east Asian countries, R22 refrigerants still seems is come. Nonetheless, the transformation of the work is to R410A, five years later, the refrigerant R410A share will increase by 25%.

Three, can effect comparing higher frequency conversion control, the development speed

In Japan, in order to satisfy the "energy saving method, energy-saving amendments" is intensifying competition. So, as is shown in table 1, major manufacturers of 2.8 KW type refrigeration/heating average has reached 6.01 - can 5.89. These room air compressor is used in rotary, swing or scroll type. These room air-conditioner has been upgraded to a high-end type, use R410A refrigerants, USES frequency conversion control and high efficiency dc motor. In order to prevent global warming, the world is very necessary energy orientation. China is ready to join WTO as turning point, the energy-saving regulation legalization.

Guangdong beauty zhi compressor Co., LTD K.K of Mr. Umashiro: in 2005, China's room air conditioner compressor, dc frequency ratio will rise to 30%.
