A Nissan A/C compressor is the part of the air conditioning system that moves the low-pressure coolant vapor into the high-pressure side of the system.
What a Nissan A/C Compressor Does
This is how a Nissan A/C system works:
- The compressor pumps the warm coolant vapor into the condenser.
- The condenser cools the vapor, transforming it into a liquid.
- The liquid coolant is pumped into the evaporator. Warm air passes over the evaporator on its way into the cabin, and the liquid coolant absorbs the heat in it. This turns the coolant back into a gas.
- The gas passes through the drier to ensure that the moisture in the coolant/lubricant mixture has been absorbed and to prevent liquid coolant from entering the compressor.
- The compressor sucks the warm coolant vapor in and pumps it out into the condenser.
There are other elements in the system as well. An electric switch on the side, called a clutch, turns the unit on and off, depending on how much cold air is needed to obtain the right temperature mix in the car. Another temperature-regulating part in the evaporator, the thermal expansion valve, determines how much coolant to allow into the evaporator to achieve the desired temperature. Any of these Nissan A/C parts can suffer damage or leaks, which can cause minor problems like decreased efficiency or major problems, such as a complete failure of the system.
A-Air sells A/C system parts for dozens of different car brands, including Nissan, Toyota and Hyundai. Both new and rebuilt parts are available for R-12 and R-134a coolant systems.
