A supercooling release material, which releases a supercooled state of a cold storage material including one or more types of alkylammonium halide aqueous solutions that generate a hydrate by being cooled to a hydrate generation temperature or lower, includes: an alkylammonium ion included in the cold storage material; and a metal halide ion which has, as a constituent element, a halogen element included in the cold storage material. The supercooled state of the cold storage material can be reliably released by using the supercooling release material having such a configuration.

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.

Air conditioning system

There is provided a heat storage material capable of recovering/storing thermal energy such as exhaust heat energy or sunlight, and a heat utilization system using the same. The heat storage material of the present invention comprises a complex compound of the formula (I), wherein, R, R', A, B, C, D, A&#x2032;, B&#x2032;, C&#x2032; and D&#x2032; are as defined herein.

The present invention provides an air-conditioning system that supplies a gas to a space to be air-conditioned and/or discharges a gas from the space to be air-conditioned through a permeable membrane in order to provide an air-conditioning system that can sufficiently block suspended matter in the air such as SPM, and can sufficiently introduce outside air in which the permeable membrane is an asymmetric membrane formed of a polymeric material prepared by polymerizing a monomer composition containing a predetermined monomer.

Air-conditioning system

An asymmetric membrane contains a porous layer and a dense layer adjacent thereto. The porous layer and the dense layer are formed of a polymeric material. The porous layer and/or dense layer contains a filler. The amount of the filler is 11 parts by mass or more per 100 parts by mass of the polymeric material contained in the asymmetric membrane.

A permselective material has a polymer having an organosiloxane skeleton and containing a dispersed solid additive. When oxygen and nitrogen are passed through a membrane having the permselective material, the relation between the permeability coefficients [cm&#xb7;cm&#xb7;sec&#xb7;cm&#xb7;cmHg] of oxygen and nitrogen at a temperature of 23&#xb1;2&#xb0; C. under a pressure difference of 1.05 atm to 1.20 atm through the membrane is expressed by Formula (1): where P(O) denotes the permeability coefficient of oxygen, while P(N) denotes the permeability coefficient of nitrogen.

A reforming device includes a reforming part that subjects a hydrocarbon-based raw material to be reformed to a reforming reaction to form a reducing agent to be supplied to a reducing catalyst for reducing nitrogen oxide selectively. The reforming part has a reforming reaction region through which the raw material to be reformed passes and is reacted with supplied hydrogen atoms supplied so as to be reformed to the reducing agent. For example, a hydrogen permeable membrane having a first surface and a second surface may be provided in the reforming part to permeate hydrogen atoms from the first surface to the second surface and to produce the hydrogen atoms on the second surface. The reforming device can be suitably used for an exhaust gas control system for cleaning exhaust gas, for example.
