Why is the low pressure low and the high pressure normal in a car's air conditioning system?
1 Answers
Low pressure in the car's air conditioning system while high pressure remains normal is typically caused by a malfunction or damage to the air conditioning compressor. Below is relevant information about car air conditioning systems: 1. Air Conditioning Layout: Different types of air conditioning systems have varying layout methods. Currently, most passenger cars widely adopt integrated heating and cooling air conditioning systems. The layout involves assembling components such as the evaporator, heater radiator, centrifugal blower, and control mechanism together, collectively referred to as the air conditioning unit assembly. 2. Air Conditioning Components: Modern air conditioning systems consist of refrigeration systems, heating systems, ventilation and air purification devices, and control systems. A car's air conditioning system generally includes components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The car's air conditioning system is divided into high-pressure and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, condenser, receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, accumulator, return pipelines, compressor input side, and compressor oil sump.
