Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
In a closed absorption system based on the heat pump principle, in which a solution of working medium is vaporized in an evaporator by heat exchange with an energy source and the vaporized solution is passed into an absorber where it is brought into contact with an absorbent solution, the heat of condensation being removed from the absorber for use to condition an enclosure, the improvement comprising: (a) a pressure sealed separation means having a high pressure and a low pressure zone; (b) a semi-permeable membrane defining said high pressure zone and said low pressure zone; (c) means for passing a mixture of absorbent solution and working medium into said separator means; (d) means for pressurizing said mixture effective to separate and collect a concentrated solution of absorbent in said high pressure zone and the working medium solution in said low pressure zone by reverse osmotic flow through said semi-permeable membrane; (e) energy transfer means between said high pressure zone and said absorber to depressurize said concentrated absorbent solution; (f) means for passing said pressurized concentrated absorbent solution through said energy transfer means into said absorber; (g) expansion means connected to said evaporator; and (h) means for passing said separated working solution through said expansion means to said evaporator.
Claim 2
Dependent Claim
