How much is the compressor high pressure and low pressure normal?

What is the high and low pressure of the air conditioner?

The normal high pressure shall be1.3-1.7mpa (13-17kg/cm2 or 190-250 lbf /IN2).

The normal low pressure between them should be 0.15-0.25mpa (1.5-2.5kg/cm2 or 20-35Lbf/IN2).

Air conditioning is a room air conditioner (air con), which is an air conditioning device. It can handle the temperature, humidity, purity and airflow speed of air to meet the needs of people's production and life. The structure of air conditioner includes: compressor, condenser, evaporator, four-way valve, one-way valve and other capillary elements. Working process of specific volume pair between teeth in air-conditioning compressor. The gas compression on the rotating side of internal thread and external thread is called high pressure zone; In contrast, when the screws face each other, the volume between teeth expands, and the suction stage is called low pressure zone. These two areas are separated by the contact line between the flanks of the negative thread and the positive thread. It can be approximately said that the plane where the two spiral shafts are located is the interface between the high pressure region and the low pressure region.

What is the normal air conditioning pressure?

So this is only a range, and the pressure is related to the ambient temperature. If the ambient temperature is higher, the pressure will be higher. The normal high pressure is 13- 16. Winter ambient temperature 13bar, normal. In summer, it is 15 16bar, and the low pressure is generally 3-5bar.

It is more or less normal for automobile air conditioners to have high pressure and low pressure.

1. Measure the high and low pressure of the air conditioning system, which should be measured when the engine is idling. The normal high pressure of automobile air conditioner is1.3-1.7 MPa (13-17 kg/cm2 or lbf/in2); The normal low pressure is 0.1-0.25mpa (1-2.5kg/cm2 or 15-35Lbf/IN2). If the low pressure is higher or lower than this range, it indicates that the expansion valve is not properly adjusted. If there is something wrong with the compressor, it does not belong to this category. When the engine is in the throttle position, the measured low pressure should decrease with the increase of engine speed. The faster the engine speed, the more (faster) the pressure drops. It means that the compressor has good performance, otherwise it means that the compressor is faulty. It should be noted that the pressure of automobile air conditioner has a great relationship with the ambient temperature (the working environment of condenser).
