Air Conditioning Test Rig

This unit consists of a hermetically sealed compressor with air cooled condenser. A capillary or expansion valves are next to condensers followed by medium temperature evaporators. Electrical energy supplied to the compressor can be measured by energy meter. This Test Rig is used to perform the following experiments:
 To calculate the COP of unit.
 To calculate the refrigerating effect and HP of unit.
 To determine the sensible heat factor of air.
