| The invention is directed toward a vapor-liquid heat and/or mass exchange device that can be used in an integrated heat and/or mass transfer system. To achieve high heat and mass transfer rates, optimal temperature profiles, size reduction and performance increases, appropriately sized flow passages with microscale features, and countercurrent flow configurations between working fluid solution, vapor stream, and/or the coupling fluid in one or more functional sections of the desorber are implemented. In one exemplary embodiment of the present invention, a desorber section utilizes a heating fluid flowing in a generally upward direction and a concentrated solution flowing in a generally downward direction with gravity countercurrent to the rising desorbed vapor stream. To further increase the efficiency of the system, various types of column configurations can be used. Additionally, the surfaces of the microchannels can be altered to better transfer heat. | ||||||

| In a refrigeration system (10), an evaporator (11) and a condenser (15) are each formed of a container-like member (55). The inside of the container-like member (55) is divided into a liquid side space (12, 16) and a gas side space (13, 17) by a moisture permeable membrane (14, 18). Both the gas side spaces (13, 17) are held in a predetermined reduced-pressure condition. Both the liquid side spaces (12, 16) are placed in an atmospheric pressure condition. Water vapor provided by evaporation of water in the liquid side space (12) of the evaporator (11) passes through the moisture permeable membrane (14) and moves to the gas side space (13). The water vapor in the gas side space (13) is sucked by a compressor (21) so as to be pumped to the gas side space (17) of the condenser (15). In the condenser (15), the water vapor in the gas side space (17) moves to the liquid side space (16) and then condensates therein. | ||||||

| 210 | Mount bases for an absorption refrigerator | US735429 | 1996-10-22 | US5836663A | 1998-11-17 | Masahiro Furukawa; Sumio Ikeda; Hisao Miyazaki |
| A mount base for use with an absorption refrigerator according to the present invention comprises a plurality of pairs of legs spaced by a distance from each other and mounted to a lower side of the cabinet such as the low-temperature and/or high-temperature cabinet, and a plurality of link plates securely joined to the legs thus forming an inner space defined by four sides beneath the cabinet, and will thus be increased in the physical strength for supporting the low-temperature and/or high-temperature cabinet. When the low-temperature and/or high-temperature cabinet is shaken by e.g. earthquake, it remains supported securely by the combination of the legs and the link plates, more specifically, the legs reinforced with the link plates and thus is prevented from fracture or injury. As the low-temperature and/or high-temperature cabinet is securely supported by the legs and the link plates, its absorber, evaporator, and regenerator are protected from tilting and will hence allow the absorption refrigerator to run without interruption. | ||||||
| 211 | Appliance leveling apparatus | US228939 | 1988-08-05 | US4860553A | 1989-08-29 | Jack L. Evans |
| A leveling device is disclosed herein for automatically maintaining an absorption refrigerator and freezing unit in a level orientation which includes a ball and socket joint for pivotally mounting the unit to a fixed wall for movement about a horizontal axis. Ducts passing through the ball and socket joint interconnect freezer unit with absorption unit. A solenoid operated leveling device automatically positions the unit to a level position in response to solenoid push rods. A mercury liquid cell carried on the refrigerator unit having quadrant segments operably connects with the solenoids for selectively actuating the push rods when the liquid level changes. The ball and socket joint permits the freezer and absorption unit to automatically level itself by the gravitational pull of the earth assisted by a solenoid operated leveling device that helps position the freezer and absorption unit to a level position. A unit hold down and movable support assembly may be employed when the unit is not cantilevered from its ball and socket joint so that adjustment can be manually achieved. | ||||||
| 212 | Heat pump using liquid ammoniated ammonium chloride, and thermal storage system | US287992 | 1981-07-29 | US4386501A | 1983-06-07 | Frederick A. Jaeger |
| A thermochemical heat pump/energy storage system using a liquid ammoniated salt, that is, a salt complexed or reacted with ammonia, is described. The system, which can be used for heating or cooling an enclosure either in a batch operation or continuously, provides energy storage for both heating and cooling functions. The energy is stored predominantly as chemical energy which has substantially no limit on the period during which it may be stored. A pumpable liquid ammoniated absorbent formed by chemically combining about equimolar amounts of ammonia with ammonium chloride ("low ammoniate"), can be further ammoniated to form a "high ammoniate" containing about 3 moles of ammonia. The high ammoniate is desorbed at a heat source temperature below 100.degree. C. available from a geothermal well or the like, and preferably at a heat source temperature below 80.degree. C. available from a solar collector, a feature which is especially well-adapted for the use of solar and geothermal heat to provide cooling in a residential application. Refrigeration may be provided for commercial use with low temperature waste process streams which are now an economic burden on industry because they are unusable profitably as a heat source. | ||||||
| 213 | Heat energized vapor adsorbent pump | US092797 | 1979-11-09 | US4377398A | 1983-03-22 | Charles E. Bennett |
| A solid matrix of microporous adsorbent is utilized to provide a barrier between two bodies of a gaseous mixture of which at least one constituent is a sorbable vapor. Appropriate application of heat at the opposing interfaces of the adsorbent barrier produces a partial pressure differential across the barrier. The adsorbent material is energized from a convenient heat source; for example, solar energy. The vapor pump of the invention may be used for environmental refrigeration and may be of the open or closed type. Other uses for the vapor pump are for producing a supply of pure water from low vapor content air or for drying air by removing the vapor content. | ||||||

The relief valve as well as the distributor valves are in open and closed conditions for predetermined conditions of operation of heat energy and refrigeration requirement such that a single storage unit may be provided which has connections of the bypass conduit from one distributor valve and to another distributor valve located below for the specific heavier weak refrigeration medium-solution and above having the connections of a conduit from a pump and a solution pump for the specifically lighter rich refrigeration medium-solution. | ||||||

| 217 | Cryogenic absorption cycles | US15233271 | 1971-06-11 | US3854301A | 1974-12-17 | CYTRYN E |
| For the development of power and/or the production of cryogenic fluids, e.g., oxygen, absorption refrigeration cycles are employed. For example, one process comprises the steps of absorbing a refrigerant vapor in a liquid absorbent, increasing the pressure on resultant mixture of said refrigerant and said absorbent, distilling and rectifying the mixture into substantially pure refrigerant vapor and pure absorbent, reducing the pressure on resultant pure liquid absorbent and returning the latter to the absorbing step, cooling and condensing the refrigerant vapor to the liquid state, reducing the pressure upon the liquid refrigerant to below the triple point of the refrigerant to produce solid refrigerant, sublimating the solid refrigerant to the vapor state, and passing resultant refrigerant vapor to the absorbing step at a rate that maintains the pressure below the triple point.
