Refrigeration system

Abstract

A refrigeration system includes a refrigeration housing having an enclosed evaporation chamber and a water storage structure formed of a water pan or water pans, a water-filling pipeline extending from the outside the refrigeration housing to the evaporation chamber for guiding water to each water pan and having installed therein a water intake control valve controllable to open/close the water-filling pipeline, an air-intake pipeline extending from the outside of the refrigeration housing to the evaporation chamber and having installed therein an air-intake control valve controllable to open/close the air-intake pipeline, one or a number of heat sink pipelines extending from the outside of the refrigeration housing to each water pan for heat exchange with the storage water, and an exhaust pipeline extending from the outside of the refrigeration housing to the evaporation chamber and having installed therein a pump controllable to draw air out of the evaporation chamber.

1 . A refrigeration system, comprising:
 a refrigeration housing, said refrigeration housing comprising an enclosed evaporation chamber and a water storage structure disposed inside said evaporation chamber, said water storage structure comprising at least one water pan;   a water-filling pipeline extending from an external water source outside said refrigeration housing to said evaporation chamber for guiding water from said external water source to said at least one water pan, said water-filling pipeline having installed therein a water intake control valve controllable to open/close said water-filling pipeline;   an air-intake pipeline extending from the outside of said refrigeration housing to said evaporation chamber, said air-intake pipeline having installed therein an air-intake control valve controllable to open/close said air-intake pipeline;   a heat sink pipeline set, said heat sink pipeline set comprising at least one heat sink pipeline extending from the outside of said refrigeration housing to said at least one water pan inside said water storage structure for heat exchange with the water stored in said at least one water pan; and   an exhaust pipeline extending from the outside of said refrigeration housing to said evaporation chamber, said exhaust pipeline having installed therein a pump controllable to draw air out of said evaporation chamber.   
     
     
         2 . The refrigeration system as claimed in  claim 1 , further comprising a cooling fan disposed at one side relative to said heat sink pipeline set and adapted for causing a convection effect in a refrigeration environment outside said refrigeration housing. 
     
     
         3 . The refrigeration system as claimed in  claim 1 , wherein each said heat sink pipeline is made of a thermal conductive material, having an inner end thereof extending to the inside of one said water pan and kept in contact with the water stored in the associating water pan. 
     
     
         4 . The refrigeration system as claimed in  claim 1 , wherein each said water pan is made of a thermal conductive material; each said heat sink pipeline is kept in contact with one side of one said water pan. 
     
     
         5 . The refrigeration system as claimed in  claim 1 , wherein each said heat sink pipeline is made of a thermal conductive material for heat exchange with the water stored in the associating water pan. 
     
     
         6 . The refrigeration system as claimed in  claim 5 , wherein each said heat sink pipeline has a fluid filled therein for circulation and heat transfer. 
     
     
         7 . The refrigeration system as claimed in  claim 1 , wherein said refrigeration housing further comprises a water level measurement device installed in said evaporation chamber and adapted for measuring the amount of water stored in said at least one water pan. 
     
     
         8 . The refrigeration system as claimed in  claim 1 , wherein said water storage structure comprises a plurality of water pans arranged at different elevations, and a weight measurement device installed in a bottom side of the lowest water pan for measuring the weight of the water stored in said water pans. 
     
     
         9 . The refrigeration system as claimed in  claim 1 , wherein said water storage structure further comprises a porous water absorptive material installed in said at least one water pan to absorb the storage water, increasing the contact surface area between the storage water and the air inside said evaporation chamber. 
     
     
         10 . The refrigeration system as claimed in  claim 1 , wherein said refrigeration housing further comprises a barometer adapted for indicating the air pressure of said evaporation chamber. 
     
     
         11 . The refrigeration system as claimed in  claim 1 , wherein said enclosed evaporation chamber of the refrigeration housing is maintained in a low pressure less than 1 atm. 
     
     
         12 . The refrigeration system as claimed in  claim 1 , wherein said enclosed evaporation chamber of the refrigeration housing is maintained in a vacuum status. 
     
     
         13 . The refrigeration system as claimed in  claim 1 , wherein said enclosed evaporation chamber of the refrigeration housing is maintained in a lower pressure lower than an air pressure outside said refrigeration housing.
