Introduction to the main parts of bus air conditioner

2016-01-18 15:18:18

Bus air conditioner is mainly composed by the compressor, condenser, evaporator, expansion valve, drier, pipes, and other components. Following we will introduce the function of each components.

Compressor: compressor is the heart of bus air conditioner. It is the power source for refrigeration to have circulation within the system. The function is to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure refrigerant, which can help the refrigerant to complete the transition process from gas to liquid.

Condenser: the function of condenser is to cool the high temperature and high-pressure refrigerant steam that is discharged from the compressor. The it can be condensed to be high pressure refrigerant liquid and give it to dryer. There are three main types of condensers:  tube-piece, belt and finned tubes.
Expansion valve: expansion valve, also known as the throttle. It is the main component of automotive air conditioning and refrigeration systems. It is the cut-off point of high pressure and low pressure of bus air conditioning system.
Evaporator: through the evaporator, low-temperature and low-pressure liquid refrigerant absorbs heat around the surrounding air heat boiling vaporization, and reduced the air temperature, then cooled and evaporated into a cold air that can be supplied to cool the vehicle.
