Cooling circulation system adopting liquid nitrogen cooling water for earth cooling air conditioner

Abstract

The invention discloses a cooling circulation system adopting liquid nitrogen cooling water for an earth cooling air conditioner. The cooling circulation system comprises a solar-energy-thermal-energy-alternative heating, hot water supply and hot air supply circulation system and a geothermal system and further comprises a liquid nitrogen cooling water storage device, a gas furnace, a water source pipeline three-way circulation pump and a heat exchanger. The solar-energy-thermal-energy-alternative heating, hot water supply and hot air supply circulation system is connected with the heat exchanger through a first pipeline. The heat exchanger is connected with the liquid nitrogen cooling water storage device through a second pipeline. The liquid nitrogen cooling water storage device is connected with the water source pipeline three-way circulation pump through a third pipeline. The system is unique and reasonable in design and ingenious in conception, through connection with the existing solar-energy-thermal-energy-alternative heating, hot water supply and hot air supply circulation system, water in the system is heated through the gas furnace and cooled through the liquid nitrogen cooling water storage device, and then the water is poured into a floor heating system, so that the temperature regulation function is achieved. The system has the beneficial effects of being capable of saving energy and protecting the environment, free of emission and free of pollution.

Description

technical field [0001] The invention relates to a heating and ventilation system, in particular to a liquid nitrogen cooling water ground-cooling air-conditioning cooling cycle system. Background technique [0002] Liquid Nitrogen: Liquid nitrogen gas. It is inert, colorless, odorless, non-corrosive, non-flammable, and has an extremely low temperature. Nitrogen makes up the majority of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inert and does not support combustion. A large number of endothermic contacts during vaporization can cause frostbite. Under normal pressure, the temperature of liquid nitrogen is -196°C; 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen at 21°C. Liquid nitrogen is a colorless, odorless, low-temperature liquid and gas under high pressure. Liquid nitrogen (often written as LN2) is a liquid form of nitrogen formed at low temperature. The boiling point of nitrogen is -196°C. If the temp...
