Unformatted text preview: requested. The COP is simply put the warm air temperature divided by the highest temperature difference. COP= L H H T T T-The evaporating temperature shall be 0˚C and the condensing temperature shall be 10K higher than the warm air supply, therefore COP= 804 , 8 35 15 , 308 273,15K) C ( 10K 273,15K C 25 10K 273,15K C 25 = = + °-+ + ° + + ° K B The amount of cooling and heating by the heat pump is found by using the “Effect Factor,” ε .
