Abstract:
1. A method for testing an AC cooling circuit in a vehicle HVAC system, comprising: coupling a pressure and a prevacuum system having a pneumatic pressure source and a vacuum source to the AC cooling circuit, and after coupling the pressure and prevacuum system to the AC cooling circuit, the method for testing includes: decoupling the pressure and prevacuum system from the AC cooling circuit after prevacuuming and testing for prevacuum leaks; coupling a separate vacuum and fill system having a separate vacuum source and a fill source to the AC cooling circuit after decoupling the pressure and prevacuum system, and after coupling the vacuum and fill system to the AC cooling circuit, the method for testing includes: decoupling the vacuum and fill system from the AC cooling circuit after filling the AC cooling circuit; advancing an AC system having the AC cooling circuit to a testing station of a vehicle assembly line having the pressure and prevacuum system; and advancing the AC system to a fill station disposed downstream of the testing station of the vehicle assembly line and having the vacuum and fill system.
