- finical incentives
4
Q
List the four parts of a heat pump system
A
- Evaporator
- compressor
- condenser
- expansion valve
5
Q
Explain what is meant by coefficient of performance
A
- A COP is a measure of the efficiency of a heat pump
* It is the ratio of the energy out of the pump to the amount of energy required to operate the pump
6
Q
What is the equation to calculate COP
A
COP=heat produced by heat pump/ energy consumed by heat pump
COP=Qh/W
