The experimental unit operates as a Refrigerator such that the evaporator is in the pilot plant and the condenser is outside. What is the resulting COP max when the outside and inside air temperatures are respectively 32C and 22C and the temperature driving force in the evaporator and the condenser is 12 C? What is the resulting COPmax if the fan speed to the evaporator is increased such that the temperature driving force at the evaporator is reduced to 8 C?
