Abstract
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. The desorber of the first circuit is connected through a conduit for a volatile component of the first system of substances to the resorber or condenser of the second circuit and the evaporator of the second circuit is connected through a conduit for a volatile component of the second system of substances to the absorber of the first circuit. A branch circuit extends from a point in the second circuit to the desorber section of the first circuit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
291 words
In an absorbtion-resorption heat pump, comprising: (a) a first circulatory flow circuit, for a first system of liquid substances, including volatile components, having: (1) a desorber for separating volatile components from said first system of liquid substances, (2) an absorber, (3) a first heat exchanger, (4) first conduit means extending between said desorber and said absorber through said first heat exchanger, and (5) means for maintaining a flow of said first system of liquid substances through said first conduit means from said desorber to said absorber and from said absorber to said desorber; (b) a second circulatory flow circuit, for a second system of liquid substances, including volatile components, having (1) a resorber, (2) an evaporator for separating volatile components from said second system of liquid substances, (3) a second heat exchanger, (4) second conduit means extending between said resorber and said evaporator through said second heat exchanger, and (5) means for maintaining a flow of said second system of liquid substances through said second conduit means from said resorber to said evaporator and from said evaporator to said resorber; (c) means for conducting the separated volatile components from the desorber of said first circulatory flow circuit to said resorber of said second circulatory flow circuit; (d) means for conducting the separated volatile components from the evaporator of said second circulatory flow circuit to said absorber of said first circulatory flow circuit; and (e) a branch circuit extending from said second circulatory flow circuit to said desorber of said first circulatory flow circuit, the improvement comprising: a storage vessel in said second conduit means disposed between said second heat exchanger and said resorber; an overflow mechanism in said storage vessel; and means for communicating said overflow mechanism with said branch circuit.
Claim 2
Dependent Claim
291 words
In an absorbtion-resorption heat pump, comprising: (a) a first circulatory flow circuit, for a first system of liquid substances, including volatile components, having: (1) a desorber for separating volatile components from said first system of liquid substances, (2) an absorber, (3) a first heat exchanger, (4) first conduit means extending between said desorber and said absorber through said first heat exchanger, and (5) means for maintaining a flow of said first system of liquid substances through said first conduit means from said desorber to said absorber and from said absorber to said desorber; (b) a second circulatory flow circuit, for a second system of liquid substances, including volatile components, having (1) a resorber, (2) an evaporator for separating volatile components from said second system of liquid substances, (3) a second heat exchanger, (4) second conduit means extending between said resorber and said evaporator through said second heat exchanger, and (5) means for maintaining a flow of said second system of liquid substances through said second conduit means from said resorber to said evaporator and from said evaporator to said resorber; (c) means for conducting the separated volatile components from the desorber of said first circulatory flow circuit to said resorber of said second circulatory flow circuit; (d) means for conducting the separated volatile components from the evaporator of said second circulatory flow circuit to said absorber of said first circulatory flow circuit; and (e) a branch circuit extending from said second circulatory flow circuit to said desorber of said first circulatory flow circuit, the improvement comprising: a storage vessel in said second conduit means disposed between said second heat exchanger and said resorber; an overflow mechanism in said storage vessel; and means for communicating said overflow mechanism with said branch circuit.
Claim 3
Dependent Claim
15 words
The improvement according to claim 1, wherein said storage vessel is part of the resorber.
Claim 4
Dependent Claim
42 words
The improvement according to claim 2, wherein said first and second circulatory flow circuits are each provided with containers in which part of the liquid circulating in the respective circuit can be stored, so that said part is temporarily kept from circulating.
Claim 5
Dependent Claim
42 words
The improvement according to claim 1, wherein said first and second circulatory flow circuits are each provided with containers in which part of the liquid circulating in the respective circuit can be stored, so that said part is temporarily kept from circulating.
Claim 6
Dependent Claim
63 words
The improvement according to claim 4, wherein one of said containers is connected to the evaporator, the resorber or the second conduit means through which the liquid passes from the resorber to the evaporator, and the other of said containers is connected to the absorber, the desorber or the first conduit means through which the liquid passes from the desorber to the absorber.
Claim 7
Dependent Claim
23 words
The improvement according to claim 4, and further including means for keeping the total amount of liquid stored in said containers essentially constant.
Claim 8
Dependent Claim
26 words
The improvement according to claim 5, wherein said containers are structually integrated into at least one of the evaporator, the absorber, the resorber and the desorber.
Claim 9
Dependent Claim
23 words
The improvement according to claim 5, and further including means for keeping the total amount of liquid stored on said containers essentially constant.
Claim 10
Dependent Claim
26 words
The improvement according to claim 4, wherein said containers are structually integrated into at least one of the evaporator, the absorber, the resorber and the desorber.
