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 projector includes a cooler configured to cool a cooling target based on transformation of a refrigerant into a gas. A refrigerant generator of the cooler includes a first blower configured to deliver air to a first portion of a moisture absorbing/discharging member, a first heat exchanger, a heater, a second blower, a circulation path along which the air exhausted from the second blower circulates, and a second heat exchanger provided in the circulation path. The circulation path has a first path along which air after passing through a second portion of the moisture absorbing/discharging member flows into the first heat exchanger and a second path along which air exhausted from the first heat exchanger is delivered to the second portion. The second heat exchanger exchanges heat between the air flowing along the first path and the air flowing along the second path.

Vacuum cooling assemblies for cooling a beverage are disclosed herein. In an embodiment, the vacuum cooling assembly may include a container compartment, a container disposed within the container compartment, and at least one beverage supply line in communication with the container compartment. The at least one beverage supply line may be configured to supply the beverage to the container within the container compartment. The vacuum cooling assembly also may include at least one vapor trap in communication with the container compartment. Moreover, the vacuum cooling assembly may include a vacuum pump in communication with the at least one vapor trap. The vacuum pump may be configured to create a vacuum in the at least one vapor trap and the container compartment, causing at least a portion of the beverage to evaporate, thereby vacuum cooling the beverage within the container.

An absorption heat pump device capable of suppressing a reduction in performance as the absorption heat pump device resulting from improper control of the concentration of an absorbing liquid due to the inclination, shaking, etc. of a vehicle body at the time of mounting the absorption heat pump device on a vehicle is provided. An absorption heat pump device in which an absorbing liquid absorbs refrigerant vapor includes an evaporator that evaporates a refrigerant and an absorber in which the refrigerant vapor evaporated in the evaporator is absorbed by the absorbing liquid. The absorber includes a heat exchange section that removes absorption heat of the refrigerant vapor into the absorbing liquid and a membrane member, disposed so as to surround and cover the heat exchange section that the absorbing liquid contacts, through which the refrigerant vapor can pass but the absorbing liquid cannot pass.

The invention relates to a renewable power and/or water generator with an absorption heat transformer (AHT) providing a heat pump, an Organic Rankine Cycle (ORC) for generating power, and a coupling between the AHT and the ORC to regenerate ORC rejection heat. The AHT consists of a low pressure evaporator and a vapour absorption binary (VAB) reactor that forms the coupling between the AHT and ORC. The VAB reactor includes an absorption section with an absorber heat exchanger and a distillation section provided by a rotating centrifugal unit that includes a flooded rotating packed bed.

An absorption type chiller includes an evaporator which evaporates refrigerant; an absorber which generates an absorption liquid by mixing the refrigerant evaporated in the evaporator with an absorbent; a regenerator which heats the absorption liquid supplied from the absorber; a condenser to which refrigerant generated in the regenerator is supplied; and a heat pipe which is arranged in at least one of the evaporator and the absorber. The heat pipe includes a rib which protrudes from an inner surface of the heat pipe, and extends in a spiral shape along a longitudinal direction of the heat pipe. A width of the rib in the longitudinal direction of the heat pipe decreases toward a center of the heat pipe.
