VR144KS-TFP-402 Emerson air conditioning compressor The air conditioning compressor plays a role in compressing and driving the refrigerant in the air conditioning refrigerant circuit. Air conditioning compressors are generally installed in outdoor units. The air conditioning compressor extracts refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. It releases heat into the air through heat dissipation fins, and the refrigerant also changes from a gaseous state to a liquid state, increasing the pressure. The working circuit of the air conditioning compressor is divided into an evaporation zone (low-pressure zone) and a condensation zone (high-pressure zone). The indoor unit and outdoor unit of the air conditioner belong to the low pressure or high pressure zone respectively (depending on the working condition). The refrigerant flows from the high-pressure zone to the low-pressure zone, and is injected into the evaporator through a capillary tube. When the pressure drops sharply, the liquid refrigerant immediately turns into a gas and absorbs a large amount of heat from the air through the heat sink. In this way, the air conditioning compressor continuously works, absorbing heat from one end of the low-pressure area into the refrigerant and then sending it to the high-pressure area to dissipate into the air, playing a role in regulating the temperature.
