Abstract: An absorption-resorption heat pump comprising a first circuit including a desorber and an absorber interconnected by conduits having a heat exchanger provided therein, so that a first circulatory flow of a first system of liquid substances can be maintained by suitable means from the desorber to the absorber via one of the conduits and from the absorber to the desorber via another one of the conduits, and a second circuit including a resorber or condenser and an evaporator likewise interconnected by conduits having a heat exchanger provided therein, so that a second circulatory flow of a second system of essentially similar liquid substances can be maintained by suitable means from the evaporator to the resorber or condenser via one of the conduits and from the resorber or condenser to the evaporator via another one of the conduits.
