WebAug 5, 2015 · COP = 10,518 / 2,700 = 3.89 Based on our calculations, a four-ton water to air heat pump running in heating mode on stage 2 would have a COP of 3.89. That means for every watt of electricity used to run … WebCOP COPHP R=+1 Can you show this to be true? Refrigerators, air conditioners, and heat pumps are rated with a SEER number or seasonal adjusted energy efficiency ratio. The SEER is defined as the Btu/hr of heat transferred per watt of work energy input.
