Reasons for High Pressure Being Low and Low Pressure Being High in Car Air Conditioning

Reasons for high pressure being low and low pressure being high in car air conditioning. If the pressure gauge shows this phenomenon, and there is no shortage of refrigerant in the pipeline, but the air conditioning effect is poor, then the fault of the air conditioning compressor should be considered. There is internal leakage in the compressor, and generally, replacing the compressor can solve the problem. Introduction to Car Air Conditioning: Car air conditioning is generally composed of a compressor, an electronically controlled clutch, a condenser, an evaporator, an expansion valve, a receiver-drier, hoses, a condenser fan, a vacuum solenoid, an idle speed controller, and a control system. Car air conditioning is divided into high-pressure pipelines and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, the condenser, the receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, the accumulator, return pipelines, the compressor input side, and the compressor oil sump. Car Air Conditioning Refrigeration System: The car air conditioning refrigeration system is composed of a compressor, a condenser, a receiver-drier, an expansion valve, an evaporator, and a blower. The components are connected into a closed system using copper pipes (or aluminum pipes) and high-pressure rubber hoses. When the refrigeration system is working, the refrigerant circulates in different states within this closed system, and each cycle is divided into four basic processes: compression, heat dissipation, throttling, and heat absorption. These processes are repeated continuously to reduce the air temperature around the evaporator.
