摘要:
The present invention provides an adsorbent for adsorption heat pump and humidity-control air conditioner, which is capable of adsorbing an adsorbate therein and desorbing the adsorbate therefrom in a narrow relative vapor pressure range, and can be regenerated (desorption) at a low temperature. Also, the present invention provides an adsorption heat pump and humidity-control air conditioner using the adsorbent which can be effectively operated even by a low-temperature heat source, as well as methods of operating the adsorption heat pump and humidity-control air conditioner by effectively utilizing low-temperature exhaust heat. The absorbent of the present invention comprises zeolite containing (i) aluminum, (ii) phosphorus and (iii) iron and/or gallium in a skeletal structure thereof, which is substantially free from change in structure upon subjecting the adsorbent to adsorption and desorption of water vapor, and has an operable relative vapor pressure range in which a change in amount of water adsorption of the absorbent when changing the relative vapor pressure by 0.1 in a relative vapor pressure range of from 0.1 to 0.25 in a water vapor adsorption isotherm measured at a temperature of 25° C., is not less than 0.12 g/g.

Subjects for the invention are to provide a zeolite reduced in performance deterioration in repetitions of use or during long-term use and a process for producing the same and to provide an adsorbent comprising the zeolite and a heat utilization system or the like employing the adsorbent.The invention relates to a zeolite which has a framework density of from 10 T/nm3 to 16 T/nm3 and a carbon content of from 1% by weight to 6% by weight and satisfies the following (1) or (2): (1) the zeolite is an aluminophosphate which has a nitrogen content of from 0.5% by weight to 12% by weight and in which the aluminum may be partly replaced by Me; (2) the zeolite is a silicoaluminophosphate in which the aluminum may be partly replaced by Me and which, when burned to a carbon content lower than 0.3% by weight, retains the framework structure possessed by the silicoaluminophosphate before the burning: (provided that Me in (1) and (2) above is at least one element selected from the elements in Groups 2A, 7A, 8, 1B, and 2B of the periodic table).
摘要:
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° 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.

摘要:
In a scroll fluid compressor including orbiting and stationary scroll members having end plates and wraps in vortical form in upstanding positions on the end plates meshing with each other to define therebetween spaces for compressing a fluid introduced through an inlet line and discharging the compressed fluid through an outlet line, flat plates in vortical form having surface finishes of higher precision than the end plates are placed in valleys between the outer wraps and the inner wraps of the scroll members to enable the wrap of the orbiting scroll member to move in orbiting movement while having the forward ends of the wraps in sliding contact with the surfaces of the flat plates in vortical form. Stepped portions may be formed on the bottoms of the valleys to hold the flat plates in vortical form in place, or space may be provided between the flat plates in vortical form and the bottoms of the valleys to be filled with a filler material from outside through ducts formed in the end plates, to bond the flat plates in vortical form to the end plates to enable the forward ends of the wraps to be maintained in uniform contact with the flat plates in vortical form.
