Air



Driven by the engine of a vehicle compressor compresses refrigerant gas to a high pressure, wherein the refrigerant temperature is significantly increased. The compressed and heated refrigerant is fed to a condenser mounted on the radiator of the cooling system. The condenser cools the gaseous refrigerant that is liquefied. Liquid refrigerant enters the receiver / dryer where him apportion water, then feeds the liquid to the evaporator located in a block heater in the car. In the evaporator, the liquid refrigerant evaporates, turning into a gaseous state, and reduces the temperature of the air entering the cabin. Further, refrigerant gas enters the compressor and the cycle repeats again.

C relay circuits controls the condenser fan and compressor. Relay control is carried out the engine control unit. If the coolant exceeds a certain temperature, the engine control unit switches off the relay, causing the air conditioning system is switched off. When starting the engine or the acceleration of the car engine control unit turns off the relay, causing the air conditioning system is switched off for 5 seconds.

The fan blows air through the evaporator core, thereby increasing the flow of cooled air supplied to the interior of the vehicle. The fan speed is determined by the position of the fan switch and resistor unit.

The conditioner compressor is a primary element of the air conditioning system. If the air conditioning compressor fails, there is no compression and displacement of the refrigerant circuit for the air conditioning system. The conditioner compressor is driven by a belt from the crankshaft pulley.

Clutch air conditioner compressor includes a compressor. The clutch is an electromagnetic control.

The condenser is installed in front of the radiator. Condenser fan increases the airflow through the condenser.

Fan unit / evaporator comprises a fan motor, air conditioner switch, the core of the evaporator and the expansion valve.

The core of the evaporator functions as cooling and air drying. Upon cooling, the air moisture in the air is deposited on the evaporator and into the vehicle enters the cooled air dry.

Expansion valve allows liquid refrigerant under high pressure expand, entering the evaporator. Valve allows a certain amount of liquid coolant to prevent flooding of the evaporator.

The dehumidified air can be reheated while passing through the heater matrix. Radiator heater heats passing through the hot coolant.

The receiver / drier for receiving liquid refrigerant from the condenser, where it is removed from the water and then the refrigerant flows to the evaporator.

The air conditioning system filled with refrigerant R-134a.
