  • Patent number: 5601793
    Abstract: A small-capacity multi-purpose batch plant comprises a multi-floor type structure and reaction vessels with jackets for heating and/or cooling. The jacket consists of two halves which are attachable to and detachable from the vessel by closing and opening. The vessels are transported to any position in the structure by stacker cranes and/or conveying trucks in horizontal directions in the same stages and in vertical directions between the different stages. Heating and cooling of the vessels can be done with any heating and cooling media. The usable temperature range is wide, and there is no risk of distortion and cracking at the welded parts of the vessels due to thermal stress. Processes in which transfer of the liquid, particularly, separation of two phases or dropping is involved can be carried out without using pipings and pumps, and thus, contamination is minimized.

  • Patent number: 5279359
    Abstract: Apparatus and process are disclosed for sorption heat pumping at high efficiency in a smooth and continuous manner using a multiplicity of intermittent cycle triplex sorption modules. The hermetically sealed trisorption modules, each of which contains at least two solid sorbents, are free of pumps, valves, restrictors, or any similar devices for flow control of refrigerant or sorbent. The preferred refrigerant is ammonia and the preferred sorbents are the solid type with monovariant equilibrium, e.g., BaCl.sub.2, SrCl.sub.2, CaCl.sub.2, MnCl.sub.2, FeCl.sub.2 and SrBr.sub.2. The apparatus is preferably adapted for residential or small-scale commercial space-conditioning applications, and operates at double-effect efficiency in both the heating and cooling modes without inter-module heat transfer.

  • Patent number: 5259927
    Abstract: An apparatus for thickening liquids with solid contents has a container receiving the liquid and a vapor outlet and a heater, which is positioned in the liquid column in the container. The heater is constructed as a rotor rotating in the container and is formed from a plurality of substantially parallel plates arranged with a limited axial spacing and extending outwards from the rotor axis, every second space between adjacent plates forming a heating chamber sealed with respect to the liquid, while the spaces located between the same close to the rotor axis and on the circumference thereof are open towards the container interior.

  • Patent number: 5240069
    Abstract: A new cooling system for a jet engine integral starter/generator incorporates an array of thermosyphons in the rotor of the starter/generator in an off-axis geometry. The condenser sections of each thermosyphon extend out from the rotor into a coolant flowpath. Fins surrounding the condenser sections are oriented to increase the flow of coolant around the starter/generator. Asymmetrical balancing wicks partially cover the inside wall of the evaporator sections of each thermosyphon. The balancing wicks have the general shape assumed by a liquid working fluid during off-axis rotation. The wick cross-sectional shape is generally that of a crescent. The balancing wicks absorb working fluid when the rotor is not rotating so that the rotor will have generally the same balance at startup as it will have during full rotational speed operation.

  • Patent number: 5237831
    Abstract: An air conditioning apparatus (1) is disclosed which includes a pair of adjacent parallel air ducts, namely a conditioned air duct (4) and an ambient air duct (5), wherein the ducts (4,5) have a common side wall (7). A fan (14) delivers an air stream through the conditioned air duct (4) to condition the air stream. A fan 15 delivers ambient air through the ambient air duct (5). Mounted within the ambient air duct (5) is a refrigeration unit having a condenser (20) and an evaporator (21). The condenser (20) and evaporator (21) are slidable between the two ducts (4,5) along tracks (43,46) extending through openings (25,26) in the side wall (7) to condition air passed through the conditioned air duct (4) to a pre-set desired condition.

  • Patent number: 5201196
    Abstract: A heat pipe is disclosed for use in a vapor-absorption heat pump to provide high efficiency heat transfer between first and second fluids in contact with opposing first and second faces of the heat pipe. Although preferably disk-shaped and adapted for rotation for use in compact heat pumps, the heat pipe may be used in heat pump applications requiring other shapes, and may be either fixed or moving. In a further aspect of the invention, a vapor-absorption heat pump is provided incorporating at least one such heat pipe in at least one component thereof.

  • Patent number: 5123479
    Abstract: A Perkins tube type rotary heat exchanger of improved efficiency wherein the Perkins tube evaporation sections are outwardly displaced from the condensation sections by offsetting and/or splaying, to substantially occupy the evaporation sections with Perkins tube working fluid while substantially eliminating the presence of fluid from a major portion of the condensation sections during operation of the heat exchanger. This has the effect of maximizing the internal evaporative area within the evaporation sections and also of maximizing the internal condensing area within the condensation sections of the Perkins tubes, thereby materially increasing the energy recovery and effectiveness of the heat exchanger.
