System for cooling an object or a space with an endothermic salt solution and a distillation membrane

A method for extracting heat from an object or a space;

• the method comprising:
• configuring an interoperable refrigeration process loop, a dehydration process loop and a distillation membrane module with a feed chamber and a permeate chamber;
• the refrigeration process loop comprising:
• (i) a first reservoir containing a quantity of a water soluble endothermic salt solution, the first reservoir salt solution at a temperature T1;
• (ii) a first piping system for movement of the endothermic salt solution;
• (iii) a cooling unit for absorbing heat from at least one of an object or a space, and transferring the heat to the salt solution thereby increasing the temperature of the salt solution to T3;
• (iv) a temperature monitoring system for measuring and comparing the temperature of the salt solution in the first reservoir and the salt solution passing through the cooling unit in the first piping system;
• (v) a plurality of first piping system valves operable to control flow of the salt solution within the first piping system;
• (vi) a pump for pumping the salt solution within the first piping system between at least one of the cooling unit and the distillation membrane module, wherein the salt solution initially is pumped through the cooling unit and recirculates to the first reservoir until the first reservoir salt solution temperature T1 equilibrates with the temperature T3 of the salt solution in the cooling unit at which time the system for cooling activates the dehydration process loop and the first piping system valves restrict flow to the cooling unit with salt solution at temperature T4 being pumped instead to the feed chamber of the distillation membrane;
• the dehydration process loop comprising:
• (i) a second reservoir containing a quantity of water, the quantity of water at a temperature T2;
• (ii) a second piping system for movement of the water;
• (iii) a plurality of valves operable to control the flow of water within the second piping system;
• (iv) a pump for pumping the water within the second piping system, the second piping system valves directing water at temperature T2 to the permeate chamber of the distillation membrane;
• wherein
• opposing chambers of the distillation membrane facilitate extraction of the permeate water from the salt solution due to the temperature differential (ΔT=T4−T2) of the two fluids;
• drawing permeate water from the distillation membrane into the second piping system causing the weight percent of salt in a concentrated salt solution to increase beyond the point of saturation;
• thereby
• inducing crystallization in the salt solution returning to the first reservoir via the first piping system,
• rehydrating the saturated salt solution in the first reservoir due to the presence of a salt solution at a lesser salt concentration than the concentrated salt solution resulting in an endothermic reaction that lowers the temperature of the salt solution in the first reservoir thereby causing the temperature monitoring system to re-initiate the refrigeration process loop;
• and pumping the salt solution from the first reservoir through the first piping system into the cooling unit to achieve the desired cooling of the object or space.
