DOMESTIC REFRIGERATOR TUTOR

A domestic refrigerator is one of the simplest of refrigeration devices widely used all over the world. It uses a fractional HP hermetically sealed compressor, a natural convection condenser, a capillary tube as an expansion device, and direct expansion type roll-bond evaporator. As far as the controls are concerned, an ON-OFF type thermostat controls the average temperature of the refrigerator. The inside heat transfer takes place by natural convection and convective currents set due to density difference of cold and warm air.

List Of Experiments:

1. To study construction and working of a domestic refrigerator.
2. To plot the cycle on P-H Chart.
