Refrigeration Test Rig

This unit consists of a hermetically sealed compressor with air cooled condenser. A capillary or expansion valves are next to condensers following by medium temperature evaporators. Electrical energy supplied to compressor can be measured by energy meter. This apparatus is used to perform the following experiments:

 To determine COP of unit.
 To draw P-H Chart.
 To draw T-S Chart.
