Cold Storage Trainer:
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.
EXPERIMENTS - To determine COP of unit.
