Abstract: A container for a refrigerating machine has: a storeroom storing a stored objective; a housing chamber housing an evaporator and an evaporator fan and guiding an inside air in the storeroom to flowing back to the storeroom after passing through the evaporator; a first ventilation duct connected to the housing chamber and having a first blower fan and a first heat storage body; a second ventilation duct connected to the housing chamber and having a second blower fan and a second heat storage body; and a controller controlling the first blower fan and the second blower fan. The controller controls the first blower fan and the second blower fan and switches between (i) a mode in which an outside air inflows through the first ventilation duct, and the inside air outflows through the second ventilation duct and (ii) a mode in which an outside air inflows through the second ventilation duct, and the inside air outflows through the first ventilation duct, at a specified time interval.

Abstract: As a permeable membrane of an air conditioning system that performs as supply to a space to be air conditioned through the permeable membrane and/or gas discharge from the space to be air conditioned through the permeable membrane, an asymmetric membrane is used. The asymmetric membrane is made of a cyclic olefin addition polymer obtained by addition polymerization of a cyclic olefin functionality siloxane, or by addition polymerization of the cyclic olefin functionality siloxane and a cyclic olefin compound, and in which a rate of a structural unit derived from the cyclic olefin functionality siloxane is 5 to 100 mol % of the addition polymer, and a number average molecular weight (Mn) is 10,000 to 2,000,000 in terms of polystyrene conversion measured by a GPC using tetrahydrofuran as a solvent.

Abstract: A ventilating device includes a housing; a gas concentration detector; a passage portion defining an outside air passage and an inside air passage; a permeable membrane disposed at an interface between the outside air passage and the inside air passage; an air sending portion to generate at least one of a flow of outside air in the outside air passage and a flow of inside air in the inside air passage; and a controller. The controller controls at least one of the flow of inside air and the flow of outside air by controlling the air sending portion, based on a gas concentration of a predetermined gas detected by the gas concentration detector.
