Abstract: 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.

Abstract: 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.

Abstract: 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.
Abstract translation: 热交换器适于冷却用于冷却装置或区域（例如建筑物内部）的冷却剂（例如，水），例如在能量成本和使用峰值期间，以节省能源和能源成本。 该热交换器包括具有一个或多个制冷剂循环器与储罐底部接触的冷却剂储罐。 循环器使用具有比冷却剂更冷的冷冻温度的制冷剂，罐上的冷却剂在其上形成一层冰。 旋转刮刀从每个循环器向上延伸穿过罐底板，当刮板形成时，刮刀用于从地板上移除薄层的冰层。 所得到的冰芯片相对较小和较薄，因此其体积具有相对较大的表面积，以使冷却剂最大程度地熔化和快速冷却。

Abstract: 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.

Abstract: 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.

Abstract: The intermittent absorption system with a liquid-liquid heat exchanger includes two generator/absorber units that operate out-of-phase, a solar collector unit, a dephlegmator, a condenser unit, an evaporator, and valves to control the flow of aqua-ammonia coolant through the system. The system operates on a two-day cycle. On the first day, during the daytime, the first generator/absorber unit generates liquid ammonia, while on the second day of the cycle, the roles are reversed, the second generator/absorber unit generating liquid ammonia. At the start of each day, one generator/absorber unit is partially pressurized and the other partially depressurized by liquid-liquid heat exchange between their heat exchangers, followed by disconnecting the heat exchangers from each other and connecting the generator to the solar collector to complete pressurization. The liquid-liquid heat exchange between the generator/absorber units reduces the heat required from the solar collector to generate liquid ammonia refrigerant, improving the coefficient of performance.
