Abstract

The invention discloses a vacuum fresh-keeping refrigerator utilizing water as refrigerating fluid. A plurality of refrigerating bins are distributed in a refrigerator body in an array mode. The refrigerating bins are all connected with a vacuum pump through pipes and electromagnetic valves. The vacuum pump removes gas in the multiple sealed refrigerating bins so as to reduce the gas pressure in the refrigerating bins, and water of food and water in water storage tanks in the refrigerating bins evaporate to absorb heat so that the food can be kept at the temperature of zero or kept frozen; the water in the water storage tanks is used for providing refrigerants for food containing little water, and people can add water after the water in the water storage tanks is used up. Due to the fact that water is used as the efrigerating fluid, no substance polluting the atmosphere is generated, the stored food can be prevented from being tainted by other odor, and refrigeration is uniform.

Description

technical field [0001] The invention relates to a vacuum fresh-keeping refrigerator, in particular to food fresh-keeping and freezing. Background technique [0002] Current refrigerators use chemical refrigerants, some of which can destroy the ozone layer of the atmosphere, such as Freon. Contents of the invention [0003] The invention provides a vacuum fresh-keeping refrigerator, which utilizes water as a refrigerant, and distributes a plurality of refrigerating chambers in an array in a box body, and the plurality of refrigerating chambers are connected to a vacuum pump through pipelines and solenoid valves; The degassing chamber is used to reduce the gas pressure in several refrigeration chambers, and the water in the water storage tank in the refrigeration chamber is used to evaporate and absorb heat from the moisture of the food itself, so as to keep the food at zero or frozen state. The water in the water storage tank is used for Provide refrigerant for foods with ...
