Energy equation m h water cooler
WebThere are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through … WebThe ratio of the refrigerant mass flow rate flowing through the additional evaporator to the refrigerant mass flow rate flowing through the MT evaporator depends on the required cooling capacity, i.e., as the cooling capacity decreases, the more refrigerant flows through the additional evaporator.
