# What will be the COP and power consumption by the cycle.

## A heat pump working on Reversed Carnot cycle takes out 6 kW per minute of the system while working between temperature limits of 300K and 200K. COP and power consumption by the cycle will be ____

a. 1, 2 kW/min

b. 3, 1 kW/min

c. 3, 2 kW/min

d. 2, 3 kW/min

Correct Answer : c. 3, 2 kW/min

**Explanation :**

COP of the heat pump cycle = T_{1} / ( T_{1} - _{T1} )

=300 / (300 – 200)

=3

Refrigerating effect = 6 kW/min

Therefore,

Work Done = Refrigerating effect / COP

= 6/3

=2 kW/min

= Power consumed
