What is the pressure for car refrigerant charging?
1 Answers
Car refrigerant charging pressure is 150 to 250kpa for low pressure and 1300 to 1500kpa for high pressure. Here are the relevant details: 1. Charging automotive refrigerant: It can be charged from either the high-pressure side or the low-pressure side. These two methods differ significantly due to the different states of the refrigerant being charged. High-pressure side charging involves liquid refrigerant, suitable for the initial charging after leak detection and vacuuming. Note that this method requires the engine to be off, and the refrigerant tank must be inverted. The other method, low-pressure side charging, involves gaseous refrigerant and is slower, typically used for refrigerant replenishment. 2. Precautions: When disconnecting, act quickly to avoid excessive refrigerant leakage.
