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.

Expansion Valve
Purpose
The expansion valve atomizes liquid refrigerant to facilitate cooling of
the evaporator.
Function
The expansion valve reduces the pressure of liquid refrigerant rapidly to
facilitate vaporization of the atomized refrigerant at the evaporator, and adjusts
the refr ...
