Abstract

PURPOSE: To provide a control means, which controls the flow rate of the cooling medium such that the sum of the cooling medium temperature difference between the outlet and inlet of an evaporator in the freezing cycle and the compensation value given according to the temperature of the cooling medium at the inlet of the evaporator and also permits efficient operation of the room cooling system.
