Abstract
The substitution scheme for a household refrigerator in the form of an equivalent active two-port network, with an evaporator as the input clamps, and a capacitor as the output ones is considered. The mathematical model of the refrigerator as two-port network is developed as a system of two equations of thermal balance with respect to the temperature difference and heat flow rate, which is transformed during refrigerating machine operation. The definitions of idle speed and short circuit modes with regard to the refrigerator are given. The developed model of the refrigerator as two-port network is intended for use in SMART refrigeration systems.
