An absorption heat pump apparatus absorbing refrigerant vapor using absorption liquid includes a container having a liquid storage portion storing a solution made of absorption liquid or a refrigerant; a heat exchanger installed in the container, and through which a heat exchange fluid flows; a pumping member pumping the solution in the liquid storage portion upward using the rotation thereof; and a coating member rotating integrally with the pumping member, and provided so as to radially extend outward from the center of rotation of the pumping member, and coating an outer surface of the heat exchanger with the solution pumped upward, wherein while the solution pumped upward moves to the center of rotation due to the rotation of the pumping member, and then radially moves outward from the center of rotation, the outer surface of the heat exchanger is coated with the solution through the coating member.

This invention relates to using a eutectic mixture of two ionic liquids, as an absorbent material in an absorption chiller. The invention provides an absorption chiller comprising a mixture of a refrigerant and an absorbent, and the absorbent is a eutectic mixture of two ionic liquids.

This invention relates to using a guanidinium-based ionic liquid as an absorbent material in an absorption chiller. The invention provides an absorption chiller comprising a mixture of a refrigerant and an absorbent, and the absorbent is a guanidinium-based ionic liquid. A preferred refrigerant is water. This invention also provides a method for synthesizing N,N,N′,N′,N″,N″-hexamethylguanidinium acetate.

The invention relates to a module for a heat pump, comprising an adsorption-desorption region, wherein in the region a bundle of pipes through which fluid can flow is arranged and a housing encloses the pipe bundle and a movable working medium in a sealing manner, wherein a supporting structure forms a mechanical support of a wall of the housing against the action of an external pressure.

The invention relates to a method for carrying out a heat transfer between alternately working adsorbers (Ad1, Ad2) in an adsorption refrigeration installation comprising an external cooling circuit (Kw) and an external heating circuit (Hw). The method is characterized by a closed heat transfer circuit, connected between the first and the second adsorber, comprising a heat transfer medium (Wm) circulating therein, a heat transfer with the external cooling circuit (Kw) being carried out in the heat transfer circuit via a first heat contact and a heat transfer with the external heating circuit (Hw) being carried out via a second heat contact.

An air-conditioning system which may be included in a motor vehicle may include a single pair of tube-and-plate heat exchangers arranged within a common vacuum enclosure, the heat exchangers selectively coupled with a heat source, a radiator, and an air-conditioning core. During an adsorbing/evaporating mode, coolant may circulate between a first heat exchanger and the radiator and vapor may evaporate from the surface of non-adsorbent-coated plates of the second heat exchanger and be adsorbed at adsorbent-coated plates of the first heat exchanger while coolant circulates between the second heat exchanger and the core. During a desorbing/condensing mode, coolant may circulate between a heat source and the first heat exchanger to effect desorption of vapor from the adsorbent in the first heat exchanger, while melting PCM in the core exchanges heat with air blown through the core to provide cooling.

An air conditioning and water producing system includes a heat pumping unit and a membrane contactor in thermal communication with the heat pumping unit. The membrane contactor is configured such that a first brine flow is cooled by the heat pumping unit and diluted at the membrane contactor. A distiller is in thermal communication with the heat pumping unit and the membrane contactor such that a second brine flow is heated by the heat pumping unit and conveyed through the distiller. Thermal interaction between the second brine flow and the first brine flow flowing through the distiller extracts water from the second brine flow.

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.

In one embodiment, the present invention relates to the use of ionic liquids and gas refrigerants in a refrigerant composition in a temperature adjustment system, such as a refrigeration system.
