The method combines different electrolyte solutions having the same solvent. The solution is successively compressed and vaporized at different temperatures and the vapor is successively absorbed by the second solution that exhibits higher negative deviation, at higher temperature. The absorption heat of each absorber is recovered by the next evaporator. The more evaporator-absorber pairs that are used the higher the temperature lift or the created pressure ratio. Finally the vapor returns to the first solution at high temperature. Electrolyte is dissolved and rejected from each solution to achieve total heat recovering and the very high efficiency of the cycle. Gas absorption is suggested instead of solvent vapor.

The present invention relates to a triple-effect absorption chilling apparatus adopting a structure of an anti-parallel cycle in which an absorber and a first regenerator are connected in series, a second regenerator and a third regenerator are connected in parallel with the first regenerator, and the solution through the second regenerator and the third regenerator is returned to the absorber. Therefore, according to the present invention, it is possible to improve efficiency by acquiring a higher coefficient of performance than conventional absorption refrigerators, and to reduce energy consumption.

A system includes an electrochemical regenerator configured to receive a first solution having a first salt concentration and output a second solution having a second salt concentration lower than the first salt concentration and a third solution having a third salt concentration higher than the first salt concentration. The first and second solutions are sent to first and second reservoirs respectively absorb and emit heat in response to a phase change of one of the solutions. The absorption or emission of heat can be used in a heat pump system.

A method of generating electric power includes expanding a flow of exhaust gas from a combustion process as the exhaust gas passes through a turbo-expander disposed on a turbo-crankshaft. The flow of exhaust gas from the turbo-expander is routed through an absorber section of an open cycle absorption chiller system. Water from the exhaust gas is absorbed via a first refrigerant solution disposed in the absorber section as the exhaust gas passes through the first refrigerant solution and out of the absorber section. The flow of exhaust gas from the absorber section is compressed as the exhaust gas passes through a turbo-compressor disposed on the turbo-crankshaft. Electrical power is generated from a bottoming cycle generator disposed on the turbo-crankshaft.

The turbo-expander is operable to rotate the turbo-crankshaft as a flow of exhaust gas from a combustion process passes through the turbo-expander. The turbo-compressor is operable to compress the flow of exhaust gas after the exhaust gas passes through the turbo-expander. The open cycle absorption chiller system includes an absorber section that is operable to receive the flow of exhaust gas from the turbo-expander. The absorber section includes a first refrigerant solution that is operable to absorb water from the exhaust gas as the exhaust gas passes through the first refrigerant solution.

A climate-control system may include a first fluid circuit, a desiccant system, and a second fluid circuit. The first fluid circuit may include a desorber, an absorber, and an evaporator. A first fluid exits the desorber through a first outlet and flows through the evaporator and a first inlet of the absorber. A second fluid exits the desorber through a second outlet and may flow through a second inlet of the absorber. The desiccant system includes a conditioner and a regenerator. The conditioner includes a first desiccant flow path. The regenerator includes a second desiccant flow path in communication with the first desiccant flow path. The second fluid circuit circulates a third fluid that is fluidly isolated from the first and second fluids and desiccant in the desiccant system. The second fluid circuit may be in heat transfer relationships with the first fluid and the first desiccant flow path.

The coolant container is fluidly connected to the absorber container in a valve open position and is fluidly separated from the absorber container in a valve closed position. The coolant changes to a gaseous phase in the coolant container to cool the contact element. The fluid line conveys the coolant in the gaseous phase from the coolant container to the absorber container, and the absorber material absorbs the coolant in the gaseous phase.
