A cooling system for refrigerators and a defrosting method performed using this cooling system.

Abstract

This invention relates to a refrigeration system (1) that enables the defrosting process for refrigerators with low energy consumption and a defrosting method using this refrigeration system (1). The refrigeration system (1) consists of a compressor (2) that circulates the refrigerant as a closed loop, ensuring that the first and second compartments of refrigerators, which have at least one first compartment and at least one second compartment kept at different temperatures, are kept at the desired temperatures; a condenser (3) that allows the heat of the refrigerant in the superheated vapor phase, which is compressed by the compressor (2), to be released; at least one first evaporator (4) that creates a cooling effect in the first compartment by drawing heat from the first compartment; and a first capillary element (5) that creates a throttling effect by providing a pressure drop to the refrigerant that changes its temperature in the condenser (3) and passes into the liquid phase before entering the first evaporator (4).It includes at least one second evaporator (6) which creates a cooling effect in the second compartment by drawing heat from the second compartment, a second capillary element (7) which creates a throttling effect by providing a pressure drop to the refrigerant that passes into the liquid phase by changing its temperature in the condenser (3) before it enters the second evaporator (6), and at least one heater which is configured to heat the first evaporator (4) and / or the second evaporator (6) in order to carry out the defrosting process on the first evaporator (4) and / or the second evaporator (6) by connecting it to the first evaporator (4) and / or the second evaporator (6).
