A regenerator accumulates cooling generated by expansion of refrigerant gas, and the regenerator includes a regenerator material which is made of a nonmagnetic material, a regenerator material which is made of a magnetic material, a container which includes a high temperature end and a low temperature end, and which accommodates the regenerator material made of the nonmagnetic material at the high temperature end side and the regenerator material made of the magnetic material at the low temperature end side. The container further accommodates an insertion member which narrows a passage area of the refrigerant gas flowing to a region accommodating the refrigerator material made of the magnetic material so that the passage area of the low temperature end side is narrower compared to the passage area of the high temperature end side.

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 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.
