  • Publication number: 20050022963
    Abstract: A waste heat source (100) is used to heat a high temperature heat transfer fluid which is used to heat an absorption heat transfer machine (10) having a generator (20), an absorber (30), a condenser (40), and an evaporator (50) operatively connected together. The high temperature heat transfer fluid can also be used to heat a load (190) such as a room space or a process. The waste heat source (100) can also be used to heat an intermediate heat transfer fluid, which can be used to heat a second load (175) such as a space, a process, or an absorption heat transfer machine. Novel flow control devices (70, 60) for controlling the flow of weak solution from generator (20) to absorber (30) or of refrigerant from condenser (40) to evaporator (50), respectively, are also described.

  • Patent number: 5704417
    Abstract: A fluid heat exchange apparatus is disclosed that can be used as an absorber in an absorption cooling system. The compact absorber design uses an accordion fin assembly to direct solution downward through the absorber on a plurality of alternatively angled fins. The alternatively angled fins cause the solution to collect at each level against a thermally conductive surface. Each fin includes a plurality of house-shaped perforations that allow the solution to spill over onto the next level fin. The house-shaped perforations also allow the vapor to flow upward in effective counterflow with the solution.
