Thermoelectric refrigeration system is based on
The capacity of refrigerating machine is expressed as
The domestic refrigerator has.a refrigeration load of the order of
Round the clock cooling of an apartment having a load of 450 MJ/day requires an airconditioning plant of capacity about
One tonne refrigerator machine means that
1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0°C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW
Match the ListI (Application) with Listll (Refrigeration temperature)
The coefficient of performance of a domestic refrigerator is
Which one of the following is correct relation between (COP)_{HP} and (COP)_{R}
Relation between coefficient of performance of heat pump and refrigerator:
(COP)_{HP} = (COP)_{R} + 1
Horse power and kW required per tonne of refrigeration is expressed as
One tonnes of refrigeration is equal to
1 T.R.  3.5 kW = 210 kJ/min
