If the coefficient of performance of the refrigerator is 4.67, then what is the value of the coefficient of performance of the heat pump operating under the same conditions?
View Answer Explanation
A heat pump is used to maintain a hall at 30°C when the atmospheric temperature is 15°C. The heat loss from the hall is 1200 kJ/min. Calculate the power required to run the heat pump if its C.O.P. is 40% of the Carnot machine working between the same temperature limits.
A heat pump which runs (1/3)rd of time removes on an average 2400 kJ/hr of heat. If power consumed is 0.25 kW, what is the value of the C.O.P.?
C.O.P. of the refrigerator is always __________ the C.O.P. of the heat pump when both are working between the same temperature limits.
Which device maintains a body at a temperature lower than the temperature of the surroundings?
What does a refrigerant do?
Coefficient of performance(COP) is defined as
Which device maintains a body at a temperature higher than the temperature of the surroundings?
In a heat pump, there is heat leakage from the body to the surroundings.
What is the relation between COP of heat pump and refrigerator?
Heat leakage from a heat pump to surroundings is always greater than work done on pump.
