The Compressor is the heart of air conditioning system. Compressor has the duty to compress refrigerant to the condenser or condensation unit which delivers the high pressure refrigerant in the steam by cooling out the refrigerant with evaporator. The motor that you see from outside the hot coil is the cooling fan. After condensing, the high pressure refrigerant will send to coil cooler through the pressure reduction kit (expansion valve), reduce high pressure down and change the status to gas and lower down the temperature then use a cool coil fan to cool the coolant in the tube to cool down the room temperature and the remaining refrigerant will be pulled back to the compressor again for the endless cooling cycle until the compressor stop working.
Carrier air conditioning comes in several types and working processes with different levels of complexity, compressor which is one of the most important parts in air conditioning. The information below will assist you in learning more about different types of compressors.
