It consists of refrigeration cycle of domestic refrigerator, it consists a hermetically sealed

compressor,  air-cooled  condenser,  capillary  tube  and  a  natural  convection  type

evaporator. The evaporator is fitted with a small heater to simulate different load conditions

various measurements are provided so that power consumption, COP, theoretical and

actual refrigerating  effects  refrigerant  flow  rate  and  effect  of  door  opening  on  power

consumption can be studied and also students can visualize automatic operation of unit

using a thermostat.

SPECIFICATIONS:

  1. Compressor -  Kirioskar make having capacity of approx. 1/25 ton of refrigeration.

  2. Air - cooled condenser with natural convection airflow.

  3. Capillary tube of matched length as expansion device.

  4. Evaporator coil with an electric heater inside  insulation on all side.
