A pivot window includes a laminated body capable of rotating in a state where a first plate material is directed outdoors and in a state where a second plate material is directed outdoors. The laminated body uses at least one of solar heat, atmospheric heat, and atmospheric humidity, and provides a humidity control effect to the room in both of the state where the first plate material is directed outdoors and the state where the second plate material is directed outdoors. The laminated body is not limited to the one providing the humidity control effect, but may be the one providing a temperature control effect. The laminated body may use the concentration of a specific gas in the atmosphere such as atmospheric oxygen concentration, atmospheric carbon dioxide concentration, and atmospheric volatile organic compound (VOC) concentration, and may provide a component concentration adjusting effect to the room.

A climate-control system may include a first fluid circuit, a desiccant system, and a second fluid circuit. The first fluid circuit may include a desorber, an absorber, and an evaporator. A first fluid exits the desorber through a first outlet and flows through the evaporator and a first inlet of the absorber. A second fluid exits the desorber through a second outlet and may flow through a second inlet of the absorber. The desiccant system includes a conditioner and a regenerator. The conditioner includes a first desiccant flow path. The regenerator includes a second desiccant flow path in communication with the first desiccant flow path. The second fluid circuit circulates a third fluid that is fluidly isolated from the first and second fluids and desiccant in the desiccant system. The second fluid circuit may be in heat transfer relationships with the first fluid and the first desiccant flow path.

A refrigeration device equipped with: a cascade cycle; a storage unit having a storage space for an object to be cooled by a second evaporator; an internal temperature sensor that detects the temperature of the storage space; a control unit that determines a second rotational speed of a second compressor on the basis of a target temperature for the storage space and the detection result from the internal temperature sensor, and that determines a first rotational speed for a first compressor having a prescribed correspondence relationship with the second rotational speed; and a first power supply unit and a second power supply unit that supply power respectively to the first compressor and the second compressor on the basis of the first rotational speed and the second rotational speed determined by the control unit.

The present disclosure relates to a refrigerating device, which comprises a condenser, an evaporator, a generator, a recovery tank, a return pipeline and an air pipe. A working medium capable of changing in gas and liquid circulates in the condenser, the evaporator and the generator to cool air in the air pipe. The two ends of the air pipe are extended into a storage area to provide sufficient cold air for the air pipe and ensure an indoor temperature of the storage area.

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.
