Phase Transition Air Cooling System Utilizing a Water Sub-Cooler for Chilling Liquid Refrigerant

Abstract

A traditional refrigeration system including a compressor, condenser and evaporator and expansion valve that utilizes an additional sub-cooler downstream of the condenser for cooling liquid refrigerant prior to the refrigerant being provided to the evaporator for increased system efficiency. The sub-cooler can utilize existing groundwater, particularly water with a large amount of dissolved materials such as naturally occurring sea water, to provide for the sub-cooling effect with only a modicum of additional energy use.

1 . An air cooling system comprising:
 a compressor;   a condenser;   a refrigerant, said compressor compressing said refrigerant in said condenser from a gas to a liquid state;   an evaporator, said refrigerant in said evaporator absorbing heat to phase transition from a liquid to a gas; and   a sub cooler, said sub cooler comprising:
 an exchanger; and 
 a container including a liquid bath which is in thermal contact with said exchanger; 
   wherein, when said refrigerant is in said liquid state, said refrigerant is fed into said exchanger within said liquid bath, said liquid bath cooling said refrigerant; and   wherein, after said refrigerant leaves said exchanger, it is provided to said evaporator.   
     
     
         2 . The cooling system of  claim 1  wherein said liquid bath is corrosive. 
     
     
         3 . The cooling system of  claim 1  wherein said liquid bath comprises salt water. 
     
     
         4 . The cooling system of  claim 1  wherein said exchanger is comprised of marine grade stainless steel. 
     
     
         5 . The cooling system of  claim 4  wherein said marine grade stainless steel is coated with a polymer. 
     
     
         6 . The cooling system of  claim 1  wherein said container is placed underground. 
     
     
         7 . The cooling system of  claim 1  further comprising a sensor attached to said exchanger. 
     
     
         8 . The cooling system of  claim 1  further comprising a thermostat for controlling said cooling system. 
     
     
         9 . The cooling system of  claim 8  wherein said thermostat is connected to the Internet.
