An adsorption heat pump is provided in which water vapor can be efficiently adsorbed and desorbed using a heat source having a lower temperature than ones heretofore in use because the pump employs an adsorbent which has a large difference in water adsorption amount in adsorption/desorption and can be regenerated (release the adsorbate) at a low temperature. The invention provides an adsorption heat pump which comprises an adsorbate, an adsorption/desorption part having an adsorbent for adsorbate adsorption/desorption, a vaporization part for adsorbate vaporization which has been connected to the adsorption/desorption part, and a condensation part for adsorbate condensation which has been connected to the adsorption/desorption part, wherein the adsorbent, when examined at 25&#xb0; C., gives a water vapor adsorption isotherm which, in the relative vapor pressure range of from 0.05 to 0.30, has a relative vapor pressure region in which a change in relative vapor pressure of 0.15 results in a change in water adsorption amount of 0.18 g/g or larger.

A pulley comprises a disk and an insert. The insert is fitted into the center of the disk integrally. Linear expansion coefficient of the disk is larger than the same of the insert. A concavity is formed on a periphery surface of the insert so that both side surfaces of the concavity are slanted outwardly, i.e. a distance between the side surfaces become large in proportion to being far from the centerline of the insert. When a slanting angle is defined as an angle between the side surface and a line which is perpendicular to the centerline of the insert on a plane including the centerline of the insert, the slanting angle is set from ten degrees to forty-five degrees, preferably from fifteen degrees to forty-five degrees. The disk is made of synthetic resin such as phenol resin, and the insert is made of metal such as iron.

An air passage in an air-conditioner such as an automotive air-conditioner is selectively opened or closed by moving a position of an opening formed on a film screen relative to the air passage. The film screen is coupled to a pair of rollers, forming a curved path between the pair of rollers guided by a guiding surface. The film screen is formed by laminating a first film made of resin and a second film made of woven fabric having a higher elongation rate for a temperature rise than the first film. The second film is positioned inside of the curved path to prevent a shape of the roller or the guiding surface from being easily transferred to the film screen.

In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.

Adsorption-type refrigerating apparatus

An adsorbent which desorbs water by being heated and adsorbs water by being chilled, comprising a porous body having a pore volume of not less than 0.2 cm /g and a pore size from 0.6-1.6 nm. This adsorbent is good for an adsorptive-type refrigeration apparatus, used in an automotive air conditioner, which has an adsorbing core.
