Home » Thermodynamics » Thermodynamics Miscellaneous » Question

A heat pump absorbs 10 kW of heat from outside environment at 250K while absorbing 15 kW of work. It delivers the heat to a room that must be kept warm at 300 K. The Coefficient of Performance (COP) of the heat pump is____

1. 1.57
2. 1.69
3. 1.67
4. 0.67

Correct Option: C

By question, given: Q₂ = 10kW ;W = 15kW
Q₁ = Q₂ + W = 25kW

COP =	Q₁	= 1.67
	W
