ABSTRACT:
This invention pertains generally to the heating and cooling of enclosed spaces and, more particularly, to an air conditioning system and method.
In the air conditioning systems most commonly used today, warm air is drawn from the space to be cooled, refrigerated, and then gently blown back into that space. This type of system is generally effective in producing the desired cooling, but it is relatively expensive to operate.
Another type of air conditioning system which is less commonly employed is evaporative cooling. In that system, air is simply blown through a wet media and into the space to be cooled. This type of system is less costly to operated than a refrigerated system, but it tends to produce humidity and is less effective than a refrigerated system.
It is in general an object of the invention to provide a new and improved air conditioning system and method.
Another object of the invention is to provide an air conditioning system and method of the above character which overcome the limitations and disadvantages of the prior art.
These and other objects are achieved in accordance with the invention by providing an air conditioning system and method in which a refrigerant from a compressor is circulated through a cooling element within a hermetically sealed, thermally insulated cooling compartment, and cooled air from the compartment is delivered to a space to be cooled. In one disclosed embodiment, the cooling compartment is located at the center of a solid cube of insulative material and is heavily insulated from the ambient conditions outside the cube.
