TH159915A - Liquid nitrogen chilled water system - Google Patents

Abstract

Water cooling system using liquid nitrogen injection to exchange the cold water with the water in the container. The liquid nitrogen tube is penetrated through the water container and the liquid nitrogen injection is controlled manually. Temperature control which receives the water temperature signal from the thermometer and sends an electrical signal to activate it. Solenoid valve, liquid nitrogen entering, exchanging cold with water in the container until the water temperature Will be as desired or as set When the cold water is sucked out of the container to be used down to the preset level, the electrical signal controller opens the valve to fill the container with normal temperature water, the liquid nitrogen injection system will continue to operate according to the controller. The temperature sends an electrical signal to operate the solenoid. Open-closed closed-loop liquid nitrogen is exchanging coolness with water in the container according to the cycle as mentioned above, the resulting cold water can be used in various industries where cold water is required.
