Abstract (en)
[origin: US4368623A] A method and apparatus for the use of heat taken up at low temperature is disclosed wherein a flow of transfer medium is passed through a low temperature heat source to absorb heat. The flow then passes through multiple, sequential stages of a heat pump which successively increase in temperature whereby the flow picks up heat. The flow then releases heat to the heat receiver and subsequently passes through multiple sequential degassing stages of the heat pump. The flow releases evaporation heat and is cooled to a suitable temperature for use in the low temperature heat source. The heat pump preferably includes a two substance mixture provided within a two portion, hermetically sealed chamber.
