  • Publication number: 20200017746
    Abstract: A base fluid for heat medium contains a hydrophilic ionic liquid and water. A molecular weight of the hydrophilic ionic liquid is at or below 150. The hydrophilic ionic liquid is methylammonium nitrate. Since the ionic liquid has favorable thermal stability, the thermal stability of the base fluid for heat medium can be secured. Since the molecular weight of the hydrophilic ionic liquid is at or below 150, the base fluid for heat medium has a low kinematic viscosity. Further, since the freezing point depression effect can be obtained by dissolving the ionic liquid in water, a low freezing point can be realized.

  • Patent number: 8333079
    Abstract: 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.

  • Patent number: 7527777
    Abstract: 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.

  • Patent number: 6619071
    Abstract: 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.
