。 A refrigeration system comprising a refrigeration circuit to which a compressor, a condenser, a throttle device, and an evaporator are sequentially connected, and a defrosting heating means for supplying heat to melt frost adhering to the evaporator during defrosting. In the apparatus, a first circuit for switching between a compressor driving circuit to which the compressor motor is connected and a defrosting heating means energizing circuit formed in parallel with this circuit and connected to the defrosting heating means; a second switching element connected in parallel to an operating switch connected in series to the compressor driving circuit and the defrosting heating means energizing circuit; Accordingly, the time during which the compressor electric motor and the defrosting heating means are energized is controlled via the first switching element, and when the defrosting heating means is energized. and a timer that continues to energize the defrosting heating means for the set time period via the first and second switching elements regardless of whether the operation switch is on or off. Defrost control circuit for the device.
