same pressure limits. If COP of refrigerator is
4,what is the COP of heat pump?
(A) 3
(B) 5
(C) 4
(D) 3.4​

Answer 1

The COP of heat pump is 5

Therefore, option (B) is correct.

Explanation:

Given:

A refrigerator and a heat pump operate between same pressure limits

COP of refrigerator is 4

To find out:

COP of heat pump

Solution:

We know that

COP of heat pump = COP of refrigerator + 1

Thus,

$\text{COP}_{HP}=\text{COP}_R+1$

$\implies \text{COP}_{HP}=4+1$

$\implies \text{COP}_{HP}=5$

Hope this answer is helpful.
