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.
Claims9
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.
