Operation of vehicle air conditioning (in everyday language)

The refrigerant is circulated by the air conditioning compressor. The air conditioning compressor creates pressure in the system, the refrigerant leaves in the gaseous state through the pressure pipes of the compressor, which flows into the air conditioning cooler at high pressure and high temperature. The refrigerator is cooled by draft and the air conditioning fan. As a result of the cooling down, the coolant turns into a liquid state, which continues to circulate towards the passenger compartment and is cooled by the interior air passing through the passenger compartment's air conditioning cooler, and we can enjoy its coldness if the system is working properly. Leaving the internal cooler, it flows back into the air conditioning compressor on the suction side.

Briefly about refrigerants

Refrigerants, in addition to their pleasant cooling ability, also have two negative properties, one of which is a ODP (ODP, the English ozone depletion potential shortening ). The purpose of this scale is to classify the harmful effects of different gases on the ozone layer. The other's name GWP (GWP, say Global warming up potential) Global warming potential is used to quantify the greenhouse effect of gases.

HFC134a or R134a: 

• The ODP value is 0, it has no effect on the ozone layer 
• GWP value is 1430
• not flammable
