Abstract

The invention relates to a refrigeration system which is characterized by comprising liquid air, a heat preservation container which is capable of containing low temperature liquid air and guaranteeing the state of the liquid air, a liquid air inlet pipeline which is communicated with the heat preservation container, and is provided with a valve, a cold air outlet, an air outlet pipeline which is provided with a valve and connects the heat preservation container to the cold air outlet, and an air blower which is communicated with the bottom of the heat preservation container through an air inlet pipeline which is provided with an inlet valve. When in use, the liquid air is injected into the heat preservation container, the valve in the air outlet pipeline is opened, the air blower is started, the inlet valve is opened, and then cold air is blown out from the cold air outlet through the air outlet pipeline, thereby the temperature of an air conditioner is reduced. The refrigeration system has the advantages of low manufacturing cost, high efficiency, energy conservation, instantaneous temperature reduction, large temperature reduction range, large refrigeration capacity, low noise, environmental protection, low operation cost and strong practicability.

Description

technical field [0001] The invention belongs to a refrigeration method, refrigeration equipment or system, and relates to an energy storage type refrigeration method and a refrigeration system. Background technique [0002] In the prior art, most refrigeration equipment or systems use heat pump cooling air conditioners. Heat pump air conditioners are usually composed of compressors, condensers, expansion mechanisms and evaporators. Compressed to the condenser, the heat is discharged and re-condensed into a liquid state, and flows into the evaporator through the expansion mechanism to complete a new round of cooling and cooling process. Using a heat pump cooling air conditioner, increasing the cooling capacity will inevitably increase the various parts of the system, so that the cost of the air conditioning system will increase almost proportional to the cooling capacity, and the power consumption will also increase proportionally. Among the refrigeration media used in heat...
