摘要： Disclosed are systems and methods of intelligently cooling thermal loads by providing a burst mode cooling system for rapid cooling, and an auxiliary cooling system that controls the temperature of the thermal load and surrounding environment between burst mode cooling cycles. The system may be used to provide pulses of cooling to directed energy systems, such as lasers and other systems that generate bursts of heat in operation.

摘要： An absorption chiller includes a heating medium supply pipe configured to supply a heating medium from a heating medium pipe to a cooling water pipe; a cooling water discharge pipe configured to discharge a cooling water from the cooling water pipe to the heating medium pipe; a control valve provided on the heating medium supply pipe and the cooling water discharge pipe, respectively; and a controller configured to cause the control valve to be opened and to cause the heating medium in the heating medium pipe to be introduced into the cooling water pipe, when a temperature detected by a cooling water temperature detector is equal to or lower than a predetermined temperature, in a wet lay-up state including a state in which a cooling water inlet shut-off valve and a cooling water outlet shut-off valve are closed and the cooling water pipe is filled with the cooling water.

摘要： A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.

摘要： Embodiments of the present disclosure relate to a heating, ventilating, air conditioning, and refrigeration (HVAC&R) system that includes a vapor compression system and an absorption heat pump. The vapor compression system includes a compressor configured to circulate refrigerant through the vapor compression system, an evaporator configured to place the refrigerant in thermal communication with a low temperature heat source, and a condenser configured to place the refrigerant in thermal communication with an intermediate fluid loop. The absorption heat pump includes an absorption evaporator configured to place a working fluid in thermal communication with the intermediate fluid loop, an absorber configured to mix the working fluid in an absorbent to form a mixture, a generator configured to heat the mixture and separate the working fluid from the absorbent, and an absorbent condenser configured to place the working fluid in thermal communication with a heating fluid.

摘要： A system for obtaining a desired cooling effect that utilizes a water-soluble endothermic salt solution and pure water. The cooling effect is created by cycling between two phases, a refrigeration phase and a dehydration phase. In the refrigeration phase, a water-soluble endothermic salt solution is used as a refrigerant to absorb heat by pumping through a first heat exchanger which cools an object or an area. In the dehydration phase, the cooling process is regenerated by pumping the now heated endothermic salt solution through a distillation membrane, where the solution and pure water are continuously commingled and separated from one another through a distillation membrane to optimize the thermodynamic efficiency of the system. At least two pumps provide the motive energy to move the endothermic salt and pure water through the closed loop piping system. The concentrated salt solution leaving the distillation membrane is further cooled using a second heat exchanger to facilitate crystal formation. Once crystal formation occurs, pure water is added back to the concentrated salt solution to restart the refrigeration phase, and thus, the cooling process.
