摘要： A simple heat cascading regenerative sorption heat pump process with rejected or waste heat from a higher temperature chemisorption circuit ("HTCC") powering a lower temperature physisorption circuit ("LTPC") which provides a 30% total improvement over simple regenerative physisorption compression heat pumps when ammonia is both the chemisorbate and physisorbate, and a total improvement of 50% or more for LTPC having two pressure stages. The HTCC contains ammonia and a chemisorbent therefor contained in a plurality of canisters, a condenser-evaporator-radiator system, and a heater, operatively connected together. The LTPC contains ammonia and a physisorbent therefor contained in a plurality of compressors, a condenser-evaporator-radiator system, operatively connected together. A closed heat transfer circuit ("CHTC") is provided which contains a flowing heat transfer liquid ("FHTL") in thermal communication with each canister and each compressor for cascading heat from the HTCC to the LTPC. Heat is regenerated within the LTPC by transferring heat from one compressor to another. In one embodiment the regeneration is performed by another CHTC containing another FHTL in thermal communication with each compressor. In another embodiment the HTCC powers a lower temperature ammonia water absorption circuit ("LTAWAC") which contains a generator-absorber system containing the absorbent, and a condenser-evaporator-radiator system, operatively connected together. The absorbent is water or an absorbent aqueous solution. A CHTC is provided which contains a FHTL in thermal communication with the generator for cascading heat from the HTCC to the LTAWAC. Heat is regenerated within the LTAWAC by transferring heat from the generator to the absorber. The chemical composition of the chemisorbent is different than the chemical composition of the physisorbent, and the absorbent. The chemical composition of the FHTL is different than the chemisorbent, the physisorbent, the absorbent, and ammonia.

摘要： Sensible waste heat from industrial or other sources is boosted to useful temperature levels by combining at least one Rankine vapor generation cycle with at least one solution heat pump cycle. Waste heat is first utilized to boil off refrigerant in the Rankine cycle evaporator to provide a source of relatively high pressure vapor to an absorber in the solution heat pump. In the absorber, the vapor is contacted with a working solution of absorbent and refrigerant. As the refrigerant vapor is absorbed into solution, its latent heats of condensation and solution are given off at a temperature higher than the temperature of to a process (boosted output) stream the waste heat source. The working solution is then throttled to a relatively low pressure desorber where a portion of the refrigerant is desorbed as vapor from the solution by the further use of waste heat. The desorbed refrigerant vapor is then condensed and pumped to the evaporator for reuse. Working solution is recycled from the desorber to the absorber for reuse. Utilization of the sensible waste heat, first source is maximized by extracting successive portions of heat for use in the Rankine cycle evaporator section and then in a heat pump cycle desorber section. Multiple cycle systems are disclosed which boost the temperature of a portion of the waste heat to even higher levels than possible from the single cycle system.

摘要： This invention relates to an airconditioning system which uses a plurality of absorption chiller-cells, for refrigerating an antifreeze fluid that is circulated through fan-coil units of an airconditioning system. The anti-freeze fluid passes through refrigerant evaporators in each cell structure in a consecutive order for lowering the temperature of the antifreeze fluid gradually. More particularly, it relates to an absorption chiller-cell system having a plurality of evaporators employing multi-refrigerant circulation circuits in an absorption cycle to produce sufficient refrigerant for the airconditioning system. The invention enables the physical size of the system to be relatively small, so that the system can replace conventional electric airconditioning units for home applications. In further aspects, this invention provides an airconditioning system which includes a plurality of absorption chiller-cells that produce various kinds of capacity of the system by combining more or less numbers of chiller-cells, the invention provides also an easier and simpler solution for maintenance or replacement of chiller-cells.
