Abstract:
L'invention concerne un dispositif à échanges thermiques comprenant un dispositif thermoélectrique et un dispositif de réfrigération à absorption. Le dispositif à absorption comprend un évaporateur (100) absorbant l'énergie calorifique d'une source chaude (500), un générateur (300) alimenté en énergie calorifique par la face chaude (602) du dispositif thermoélectrique (600), un absorbeur (400) et un condenseur (200). Un boîtier (10) renferme le générateur (300), l'absorbeur (400), l'évaporateur (100) et le dispositif thermoélectrique (600). Le dispositif thermoélectrique sépare le boîtier (10) en deux compartiments, le compartiment en contact avec la face chaude (602) formant le générateur (300), le compartiment en contact avec la face froide (601) formant l'absorbeur (400) et l'évaporateur (100). Une membrane (20, 30) imperméable aux phases liquides et perméable aux phases gazeuses divise chaque compartiment en deux zones de manière à maintenir la solution liquide absorbât/absorbant uniquement dans une des zones de chaque compartiment, les zones dans lesquelles est maintenue la solution liquide absorbât/absorbant étant délimitée par le dispositif thermoélectrique (600).

The invention further relates to a respective method for heating or cooling.
Abstract:
To provide a water evaporation type cooling apparatus which uses a solid electrolytic element and which does not pose any environmental assurance problem and is silent and small-sized. A solid electrolytic element (50) is disposed to divide a closed can (51) into spaces (51a, 51b), water (53) is stored in the space (51a), and a condenser (55) is provided to communicate with the space (51b). A water storage portion in the space (51a) is connected to a water storage portion in the condenser (55) through a water passage (57), and vapor phase portions in the spaces (51a, 51b) are connected to each other through a vent passage (58). Electricity is supplied to the solid electrolytic element (50) from a DC power supply (52) to cause electrolysis of water at an anode side and generation of water at a cathode side. A thermal connection surface (59) at a bottom of the space (51a) is formed into an external shape conforming to that of an object (54) being cooled.
Abstract:
A thermal engine is disclosed which is operable as a heat pump, refrigerator, or air conditioner. Vaporized working fluid from a first evaporator, which extracts heat from elements desired to be cooled, is fed to a first region of an osmotic pump which also has a second region containing a solution of the working fluid and a preselected solute, the second region being separated from the first region by a membrane permeable to the vaporized working fluid but not to the solute. A second evaporator, which may be driven by waste heat, is operatively coupled to the second region of the osmotic pump by means of a counterflow heat exchanger having a first path for conveying relatively dilute solution from the second region of the osmotic pump to the second evaporator and a second path for conveying relatively concentrated solution from the second evaporator to the second region of the osmotic pump. Output heat from the thermal engine is obtained from a condenser which condenses vaporized working fluid from the second evaporator. The condensed working fluid undergoes constant enthalpy expansion, after which it is returned to the first evaporator.

Abstract:
Le dispositif est du type comprenant un désorbeur (100), un absorbeur (400), un condenseur (200) et un évaporateur. Le désorbeur (100) et l'absorbeur (400) sont remplis d'un mélange d'au moins deux substances miscibles formé par un fluide réfrigérant et un fluide absorbant. Le mélange est combiné dans l'absorbeur (400) dans lequel l'absorption du fluide réfrigérant par le fluide absorbant a lieu. Un moyen d'augmenter le différentiel de pression est placé entre le désorbeur (100) et le condenseur (200), de façon à augmenter légèrement la pression au niveau du condenseur (200) et/ou baisser légèrement la pression du désorbeur (100) et améliorer, ainsi, le fonctionnement du dispositif de climatisation.
