Patent number: 6029471Abstract: In refrigeration; in order to transfer heat from the heat supplier, or to the heat absorber, it is necessary that temperature gradients be maintained between said heat exchangers and the interacting medium. These temperature gradients increase the difference between the temperature of the heat supplier and that of the heat absorber. The efficiency of refrigeration systems decrease as said temperature differences increase. Said mediums, if gaseous, as they frequently are, offer great resistance to heat transfer. This results in large temperature gradients and substantially reduces refrigeration efficiency. The present invention involves enveloping the enclosed space with the enclosure heat exchanger so that less heat has to be transferred through the gaseous contents, and additional, inexpensive, heat transfer surface becomes available. The reduction in temperature gradients result in increased efficiency.Recovery of reject heat for residential type water heating is also included as a natural extension.Type: GrantFiled: March 12, 1993Date of Patent: February 29, 2000Inventor: Christopher Taylor
