Product Description

The ‘Swarg Systems & Instruments’ unit enables students to study the various parameters affecting the performance of a domestic refrigerator. It demonstrates refrigeration cycle of domestic refrigerator. It consists of 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.
