MR011R Domestic Refrigerator System Study Unit Educational Equipment Condenser Training Equipment
To study the Domestic Refrigerator System and determine its power consumption, COP, theoretical & actual refrigerating effects, refrigerant flow rate & effect of door opening on power consumption & also students can visualize automatic operation of unit using a thermostat and draw PH and T-S diagrams using different refrigerants:
a) R134a (HFC)
b) R152a (HFC)
c) R290/R600a (50% / 50% by weight) [HC] or R600a and R290
EXPERIMENTAL SETUP
210 Litter
ü Refrigerator body must be same for the different refrigerants; change can be made in compressor (hermetically sealed compressor), air cooled condenser and Expansion valve (Capillary Tube) if required
ü Refrigerator should be designed for same refrigeration capacity with different refrigerants
ü Refrigerator should be branded
ü Sensors used for pressure and temperature should be digital, branded and accurate
ü Amount of electricity consumed by every part should be measurable with an instrument (i.e. energy meter)
ü Temperature (Dry as well as wet bulb) and pressure of in/out air from condenser and evaporator should be measured
ü Suitable filter drier
ü Temperature and pressure of in/out refrigerant from every part of refrigerator should be measured
ü System should be leak proof and safe especially when using R290 /R600a refrigerants
ü System should be frost free
