Mazda CX-5 Service & Repair Manual: Condenser
Purpose
-
The condenser cools the high-temperature, highly pressurized refrigerant.
Function
-
The condenser cools the high-temperature, highly pressurized gaseous refrigerant compressed by the A/C compressor using the outside air, and changes it to liquid refrigerant.
Construction
-
The condenser is installed to the front of the radiator.
-
The condenser consists of the tube which passes refrigerant, and the heat radiation fin.
-
A sub-cooling condenser has been adopted.
-
The sub-cooling condenser is integrated with the multi-flow condenser and the receiver driver.
-
The sub-cooling condenser separates the refrigerant, cooled once by the condenser, into vapor and liquid using the receiver/drier, and by returning it to the sub-cooling part of the condenser again to cool.
-
As a result, liquefaction of the refrigerant is promoted and cooling performance is improved.
Operation
-
The high-temperature, highly pressurized gaseous refrigerant sent from the A/C compressor passes through the tube in the condenser.
-
When the air blown from the outside is exposed to the heat radiation fin, the heat of the refrigerant is captured by heat exchange, and the refrigerant changes from a gas to a liquid.
-
The liquid refrigerant is sent to the expansion valve via the receiver/drier.
Fail-safe
-
Function not equipped.
