摘要： A refrigeration cycle apparatus, in which demand control is performed to adjust electric power, includes: a compressor, a driving rotation speed; a recording device that records, as data, a relationship between the driving rotation speed of the compressor and a temperature difference between a set temperature and a detected temperature, the set temperature being set as desired as a temperature control target for a temperature adjustment target, and the detected temperature being detected by a temperature detecting device disposed at a position at which a temperature of the temperature adjustment target is detected; and a main controller that, in response to a request for the demand control, calculates the temperature difference between the set temperature and the detected temperature, retrieves, from the recording device, data of the driving rotation speed of the compressor corresponding to the calculated temperature difference, and controls the compressor based on the retrieved driving rotation speed.

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.

摘要： A solution flows through a salinate chamber and a desalinate chamber of an electrochemical cell. Solutes are moved from the desalinate chamber to the salinate chamber to create respective solvent and concentrate streams from the desalinate and salinate chambers. The concentrate stream flows to a recombination cell where it is combined with a solvent. The combination causes at least one of an absorption of heat within the recombination cell and emission of heat from the recombination cell.

摘要： Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.

摘要： An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.
