摘要： A pressure and prevacuum testing system for an AC system in a vehicle includes an air pressure source for pressurizing a cooling circuit of the AC system to a predetermined high pressure threshold and a vacuum source for prevacuuming the cooling circuit either to a predetermined prevacuum low pressure level or for a predetermined time period. The system also includes a pressure gauge for operatively measuring a pressure level in the cooling circuit. A controller is operatively connected to the air pressure source, the vacuum source and the pressure gauge. The controller compares the pressure level as measured by the pressure gauge to the predetermined high pressure threshold during a pressurized test of the cooling circuit and to the predetermined prevacuum low pressure level during a prevacuum test of the cooling circuit to determine if leaks are present in the cooling circuit.
