A QUICK COOLING DEVICE USING FREEZING CYCLE

摘要

Disclosed is a quick cooling device using a freezing cycle. An embodiment of the present invention provides a quick cooling device using a freezing cycle, including: a raw water supply unit; a tank with an outlet through which a fluid is discharged and an inlet through which the fluid flows in; a cooling coil formed inside the tank and cooling the fluid inside the tank by a heat exchange with a coolant of low temperature circulated by the freezing cycle; a compressor connected to an outlet of the cooling coil and compressing the returned coolant; a tube installed inside the tank and receiving an intake of the condensed coolant from a condenser condensing the coolant flowing from the compressor; and an expansion valve expanding the liquid coolant flowing after being heat-exchanged from the tube of the tank and supplying the expanded coolant to the cooling coil. An embodiment of the present invention relates to a quick cooling device using a freezing cycle, in which a separate heating body for securing a fluid passage when the water inside the tank is at or below a preset temperature is unnecessary.
