Novel Ways of Storing Cold

ABSTRACT
This paper describes two methods of storing cooling energy: as water cooled close to freezing, and in the ground, similar to a ground source heat pump. The low temperature water storage method is well adapted to use of industrial refrigeration equipment, and ammonia refrigerant. The second method of storing cold is to store natural cold in the ground. Dr. Ted Taylor of Princeton developed a way to use ski area snow making “guns” to make artificial ice in winter for summer cooling. This was shown to work, but the shelters were expensive. The approach taken in this paper is to use a spray tower or spray pond to cool water at or near freezing, which is then stored in the ground, similar to the way ground source heat pumps extract heat from the ground, but without the heat pump.
