What Causes Low High Pressure and High Low Pressure in Car Air Conditioning?

When the pressure gauge shows low high pressure and high low pressure in a car's air conditioning system with sufficient refrigerant in the pipelines but poor cooling performance, it usually indicates a compressor malfunction due to internal leakage. Replacing the compressor typically resolves this issue. Introduction to Car Air Conditioning: Car air conditioning systems mainly consist of the compressor, electromagnetic clutch, condenser, evaporator, expansion valve, receiver-drier, hoses, condenser fan, vacuum solenoid, idle speed controller, and control system. The system has high-pressure and low-pressure circuits. The high-pressure side includes the compressor output, high-pressure pipelines, condenser, receiver-drier, and liquid lines. The low-pressure side comprises the evaporator, accumulator, suction lines, compressor input, and compressor oil sump. Car Air Conditioning Refrigeration System: The refrigeration system consists of the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected via copper (or aluminum) pipes and high-pressure rubber hoses to form a sealed system. During operation, refrigerant circulates through this closed system in different states, undergoing four basic processes: compression, heat dissipation, throttling, and heat absorption. These cycles continuously repeat to lower the air temperature around the evaporator.

How to Check for Traffic Violations When Driving Someone Else's Car?

With the above documents and by explaining the reason to the staff at the window, you can check and handle traffic violations even if the vehicle owner is not present. Situations of traffic violations: 1. On-the-spot ticket: If a traffic police officer issues a penalty decision on the spot for a vehicle violation, you must go to the local traffic detachment or brigade to handle the violation. This type of violation must be handled at the location where it occurred; it cannot be handled back in your hometown. 2. Electronic monitoring ticket: If the violation is captured by electronic monitoring and no ticket is issued on the spot, after checking the violation record on the traffic management bureau's website, if it falls under the general summary procedure category, it can be handled in a different location.
