Q1. Explain COP of chiller
Ans. 
COP of a chiller stands for Coefficient of Performance, which is a measure of the efficiency of a chiller system.
• COP is calculated as the ratio of cooling output to the energy input required to produce that cooling output.

• A higher COP value indicates a more efficient chiller system.

• COP can be calculated using the formula: COP = Cooling Output / Energy Input.

• For example, if a chiller has a COP of 4, it means that for ev...read more
