10.11.5 Air conditioning system device
The simplest air conditioning system is arranged as follows (shown in Figure 10.16): the compressor is mounted on the engine and is driven from the crankshaft by the means of a belt. Two high and low pressure hoses are connected to the compressor, a condenser (in a form of a radiator) is installed in front of the cooling system radiator. High and low pressure hoses are connected to the condenser. The receiver-dryer is installed on the condenser, which, in turn, is connected by branch pipes to the expansion valve. An evaporator is installed inside the passenger compartment itself, which is apparently the same radiator, only in a reduced form. The whole air conditioning system is filled with a special refrigerant.
Note
It is worth adding that the air conditioner in the car is not used constantly, even in the summer. Thus, there is no need to pump refrigerant idle on the system. For this purpose, the actuation of the compressor is carried out through the electromagnetic coupling, which is integrated in a compressor pulley. This coupling separates the pulley and the compressor shaft when there is no need for air conditioning.
