The top ten brands are: Guangzhou Panasonic Wanbao, Japan's Mitsubishi, South Korea's LG, Xi'an Qing'an, Dalian Sanyo, Japan's Toshiba, Shanghai Hitachi, the United States Kelly, the United States Copeland, France Taikang.

The main varieties of Panasonic Wanbao compressors currently used in rooms are 0.5 to 3HP: T, S, R, P, K, V, six series, with a production capacity of 12 million units/year. In April 2003, it officially entered the manufacturing field of automotive air-conditioning compressors, producing three series: H, G, and V, with an annual output of 500,000 units/year. As one of the five major production bases of Panasonic Compressor Group

The air-conditioning compressor plays the role of compressing the driving refrigerant in the air-conditioning refrigerant circuit. Air conditioning compressors are generally installed in outdoor units. The air conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. It dissipates heat into the air through the radiator. The refrigerant also changes from gaseous to liquid, and the pressure increases.

The working circuit of the air conditioning compressor is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit and outdoor unit of the air conditioner belong to low-voltage or high-voltage zones respectively (depending on the working status). The refrigerant then flows from the high-pressure area to the low-pressure area, and is injected into the evaporator through the capillary tube. The pressure drops suddenly, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat in the air through the heat sink. In this way, the air conditioner compressor continues to work, continuously absorbing heat from one end of the low-pressure area into the refrigerant and then sending it to the high-pressure area for dissipation into the air, thereby regulating the temperature.
