させるようにしたことを特徴とする冷却装置。A refrigeration cycle formed by sequentially connecting a compressor, a condenser, a throttle device, and a cooler; a defrosting circuit that supplies refrigerant discharged from the compressor to the cooler and defrosts the cooler; , a compressor drive relay that has a self-holding contact and is energized by the compressor operation switch, and is connected in series with this relay and detects that the high pressure side pressure of the refrigeration cycle is higher than a predetermined value. A timer having a pressure switch that demagnetizes the relay, and a timer contact that closes for a predetermined time from the start of defrosting of the cooler, the self-holding contact of the relay and the timer contact are connected in parallel, and the pressure switch The cooling device is characterized in that when the compressor is stopped, the compressor is restarted only when the high-pressure side pressure drops to a recovery value of the pressure switch within a predetermined time from the start of defrosting. .
