What is the pressure when the car air conditioning is not turned on?

[LeLucia]

When the car air conditioning is not operating, the normal high-pressure side should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); the normal low-pressure side should range between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). Below is relevant information about car air conditioning: 1. Introduction to Car Air Conditioning: The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped. 2. Disadvantages: When the air conditioning is on, it is best for passengers not to smoke inside the car. Since the air inside circulates in a relatively enclosed environment when the air conditioning is on, firstly, smoke is not easy to dissipate, and secondly, tiny particles in the smoke will adhere to the air conditioning intake filter, causing long-lasting odors in the car. It is recommended to regularly perform professional cleaning and deodorizing maintenance of the air conditioning system.
