Cooling Capacity Calculation For Chiller

Cooling Capacity an overview ScienceDirect Topics.

Cooling capacity indicates the amount of heat the system can remove from the refrigerated space over timeIt is equal to the change in the specific enthalpy of the refrigerant in the evaporator caused by the refrigeration load multiplied by the mass flow rate of the refrigerantIt is expressed in Equations 3a and 3b.
