COP of VCRC and COP of heat pump is greater than one while COP of VARC and Air refrigeration is less than one.

COP of Heat Pump = 1 + COP of the Refrigerator.

The COP of the refrigerator and air-conditioner can be less than one or greater than one. The above formula also shows that the COP of the heat pump can never be less than one; it is always more than one.

Because COP of pump = cop of refrigerator + 1.
