What Causes Dual Low Pressure in Car Air Conditioning?

[Asher]

Dual low pressure in car air conditioning is typically caused by insufficient refrigerant, which is a common issue. Here are specific details about car air conditioning pressure: 1. Function of Pressure Gauges: Car air conditioning pressure gauges are used to monitor the cooling system. They consist of a high-pressure gauge and a low-pressure gauge, which measure the high and low pressure states of the car air conditioning system to determine if it is functioning properly. 2. Normal Pressure Values: Generally, the normal high-pressure range for car air conditioning is 1.3-1.7 MPa (13-17 bar), and the low-pressure range is 0.1-0.25 MPa (1-2.5 bar). If the pressure is either too high or too low, it indicates a malfunction in the car air conditioning system.
