Function of heat pump:

Refrigerator

The primary function of heat pump is to transfer heat from the low temperature system to the high temperature system, this transfer of heat is utilized for two different purposes, either heating the high temperature system or cooling the low temperature system. It depends upon the nature of use. The heat pump is said to be acting as a heat pump or as a refrigerator. If the purpose of it is to cause heating effect it is called as operating as a H.P. And if it is used to create cold effect, the HP is known for operating as a refrigerator.

(COP)ref = Heat received/ Work Input

= Q2/W = Q2/(Q1  - Q2) (COP)ref  = Q2/(Q1  - Q2) = T2/(T1  - T2)

(COP)HP  = (COP)ref   + 1

COP is greater while heating room than when cooling it.
