摘要： The hybrid aqua-ammonia and lithium bromide-water absorption chiller is an aqua-ammonia absorption refrigeration system integrated with a lithium bromide-water absorption refrigeration system. By integrating a solar-powered lithium bromide-water absorption refrigeration system into the aqua-ammonia absorption refrigeration system, evaporator temperatures below the freezing point of water may be generated at lower operating pressures and lower generator temperatures than in conventional aqua-ammonia absorption refrigeration systems.

摘要： The intermittent absorption refrigeration system includes a primary circuit having a generator/absorber, a dephlegmator, a condenser, an evaporator, and solar collectors to provide heat to the generator. The system also includes an ejector-based secondary circuit having a generator/absorber, an ejector, a condenser, a refrigerant storage unit, and solar collectors. Both circuits are aqua-ammonia systems, using ammonia as the refrigerant and water as the absorber liquid. The ejector permits evaporation during the daytime and storage of liquid ammonia refrigerant that is used for cooling in the heat exchanger of the primary circuit condenser and in the primary circuit absorber, thus permitting the primary circuit evaporator to operate at lower temperatures for low temperature freezing applications in the daytime, even at high ambient temperature.

摘要： The heat exchanger is adapted for cooling a coolant (e.g., water), used to cool a device or an area (e.g., building interior), such as during periods of peak energy cost and usage, to save energy and energy costs. The heat exchanger includes a coolant storage tank with one or more refrigerant circulators in contact with the floor of the tank. The circulators use a refrigerant having a freezing temperature colder than the coolant, with coolant on the floor of the tank forming a layer of ice thereon. A rotary scraper extends up through the tank floor from each circulator, with the scrapers operating to remove the thin layer of ice from the floor as the ice forms. The resulting ice chips are relatively small and thin, thus having a relatively large surface area for their volume in order to maximize melting and rapid cooling of the coolant.

摘要： The intermittent absorption refrigeration system with an ejector includes a generator/absorber unit, a solar collector unit, a dephlegmator, a condenser unit, a first evaporator, and valves to control the flow of aqua-ammonia coolant through the system, as in a conventional intermittent absorption refrigeration system. However, the present system also includes an ejector disposed between the dephlegmator and the condenser, and also a second evaporator disposed in a feedback loop between the first evaporator and the ejector, together with appropriate valves to control coolant flow through the feedback loop. The utilization of the ejector and the feedback loop in the intermittent system allows the intermittent system to produce a cooling effect during the daytime, as well as during the nighttime, which increases the coefficient of performance of the intermittent system.

摘要： The heat exchanger flow balancing system serves to substantially equalize fluid flow through essentially identical diameter heat exchanger tubes in a heat exchanger having a single inlet plenum, a single outlet plenum, and a series of equal diameter heat exchanger tubes extending therebetween. In one embodiment, a series of different diameter orifices are provided at the inlet end of each of the tubes, with those tubes farther from the single larger diameter inlet pipe to the plenum generally having smaller orifices. In another embodiment, each of the tubes is provided with a conical nozzle at its inlet end, with those tubes farther from the single inlet pipe to the plenum generally having smaller diameter nozzles. The effect is to substantially equalize fluid flow through all of the heat exchanger tubes, thus increasing the efficiency of the heat exchanger.
