Chiller Efficiency How to calculate - The Engineering Mindset

Jul 22, 2017 The imperial calculation would be: First convert BTU’s to kW’s. 8,533,364BTU/s / 3412.142 = 2,500kW. 2,500kW / 460kW = 5.4 so the COP is 5.4. This means that for every 1kW of electricity you put into the machine, you will produce 5.4kW of cooling. how to calculate the efficiency of a chiller imperial and metric.
