RAPID COOLING DEVICE USING REFRIGERATION CYCLE

摘要

Disclosed is a rapid cooling device for cooling raw water by exchanging heat with a refrigerant that circulates along a cooling coil wound around the outer periphery of a water storage tank. The present invention provides the rapid cooling device using a refrigeration cycle, comprising: a water storage tank having an inlet and an outlet formed therein; a cooling coil that is spirally wound around the outer periphery of the water storage tank in order to increase the contact area and cools the fluid in the water storage tank; a compressor connected to the outlet side of the cooling coil; a tube that is installed within the water storage tank and into which a refrigerant in a condensed state is introduced from a condenser; and an expansion valve that expands the liquid refrigerant, which moves after exchanging heat with the tube of the water storage tank, and supplies the same to the cooling coil.
