What Causes High Pressure in Both High and Low Sides of Car Air Conditioning?

[Ann]

Car air conditioning high pressure in both high and low sides can be caused by the following reasons: 1. Compressor damage. 2. Excessive opening of the expansion valve. 3. System design issues: The expansion valve is oversized, the evaporator flow resistance is too high, the low-pressure pipe flow resistance is too high, etc. 4. Poor heat dissipation of the condenser. Here is an introduction to car air conditioning: 1. Introduction: Car air conditioning refers to the air conditioning device installed in a car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped. 2. Components: Generally includes refrigeration devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.
