What is the normal value of an automotive air conditioning pressure gauge?
1 Answers
When the automotive air conditioning is running, the red gauge indicates high pressure, and the blue gauge indicates low pressure. The normal values are 1.3-1.7 MPa for high pressure and 0.1-0.25 MPa for low pressure. However, the normal pressure of the air conditioning system can also vary due to changes in external environmental conditions. Below is more information about automotive air conditioning pressure: 1. The data units on an automotive air conditioning pressure gauge generally include megapascals (MPa), bars, kilopascals (kPa), and pounds (psi). Different vehicle models may display different units, so it is necessary to convert the normal range according to the display unit of your specific vehicle. 2. The conversion between these three units is as follows: 1 megapascal equals 10 bars, equals 1000 kilopascals, equals 145 pounds.
