Resistance test at overpressure
The system is used to test for leakage at overpessure. In this application example, the test items are self-contained refrigerated air conditioner used for cooling trolley cabinets in aircraft kitchens. The refrigeration circuit of the test items consists of different compoonents such as pipes, condenser, repoiler, compressor, rupture disk, pressure switch, valve and other which are tested for leakage. The system is controlled via a PC with measurement data acquisition hardware and measurement and control software under LabVIEW.

Resistance test (Proof Pressure Test):
In this test, the resistance of the refrigeration circuit is checked at overpressure. Nitrogen is used as test gas.
Pressure Switch Test:
The pressure switch test checks the proper functionality of the pressure switch in the refrigeration circuit.
