摘要： PROBLEM TO BE SOLVED: To directly apply to a contact-type ice thermal storage device for improving practicality by the cold heat medium of a silicone compound containing fluorine with improved separation property from water and a greater specific gravity than ice and water, in the ice thermal storage device for depositing ice particles by directly performing the contact heat exchange of water and non-soluble cold heat medium. SOLUTION: A nozzle 2 is arranged at the upper end of an ice-making part 1 and two pipes are connected to the nozzle 2. More specifically, a cold heat medium 3 is circulated and supplied from one cooling medium supply pipe 3a and water 4 is circulated and supplied from the other water supply pipe 3a. Also, the cooled cold heat medium is heat-exchanged with water, and cooled water is changed into ice. Further, since ice has a lighter specific gravity than water, an ice particle 9 is generated at the upper portion of a water layer. The cold heat medium 3 that is used at this time is alkylpolysiloxane containing at least one fluorine. The cold heat medium is a non-aqueous liquid body, exchanges heat by liquid - liquid contact with water, cools water and generates a fine ice particle, and then separates a cold heat medium 10 at a lower layer.

摘要： PROBLEM TO BE SOLVED: To carry a heating medium at a low cost without being restricted by distances, by storing heat energy in the heating medium, and by carrying the heating medium in which this heat energy is stored, without the intervention of piping. SOLUTION: When the heat energy of cold sea water is stored in a heating medium to be transported, the batch in which a cold storage material is stored is loaded on a trailer. In this cold storage material, the heat energy of cold sea water is stored through a heat exchanger. The batch in which this cold heat is stored is carried to the places which require cold heat, and then the stored cold heat is taken out to be used. In this storage and carrying system of heat, the heating medium used for storing heat and heat storage facilitates the heat storage device by using the medium that can store heat sufficiently even though being small-sized. Moreover, since a pipeline is not used for carriage and transportation, the equipment cost can be decreased. If all the natural energy/unused energy is transformed into heat so as to accumulate heat, the system can be expected as the heat supply center for the community.

摘要： PROBLEM TO BE SOLVED: To more efficiently use natural energy such as the sunlight, wind power, cold of the deep sea and warm of surface water by combining, leveling and utilizing various energy which exists in the natural world and on which a usable energy quantity changes. SOLUTION: Not only power generation by the sunlight and wind power and power generation by ocean thermal energy conversion(OTEC) are used in combination, but also warm seawater taken from a surface layer of the ocean and cold seawater taken from the deep sea are used, and are used for seawater desalination and fishery-culture. Cooling of the summer period is performed by using natural energy, and growth of a plant is artificially controlled by a cooling house, and an agricultural product is stored in a cooling storage facility. In this way, cold seawater obtained from the OTEC is stored as cold from the deep sea, and can be used as a heat source of air-conditioning and heating on land, and is utilized by converting/storing the energy into/in many media such as electric power/cold by combining various energy on which an energy quantity changes.

摘要： PURPOSE:To utilize environmental water energy stably for a long period of time by introducing a non-water-soluble liquid medium of high specific gravity which has been heat-exchanged with environmental water into a heat exchanger to effect a heat exchanging action, thereby reducing fouling on the heating surface in the heat exchanger. CONSTITUTION:A non-water-soluble liquid 6 of high specific gravity stored in a recovery section 9 has been heated approximately to a temperature of river water (heat source water), so that the heat energy having been given from the river water is taken up by a heat pump 10 and the liquid 6 whose temperature has become low flows to a distributor 5. Fine sands and relatively heavy solid fine particles contained in the river water are removed at a separator 11A serving also as a filter provided in a circulation system 11 of the liquid 6. The heat-source water 3 from which a part of its heat energy has been removed by the liquid 6 at a heat exchanger tank 4b becomes lower temperature. And when the liquid 6 naturally falls in the tank 4b under the force of gravity, it flows along a passage 8 in the form of film, so that fine droplets are not generated.

摘要： PURPOSE:To effectively utilize heat source water without lowering performance of a heat exchanger in order to utilize seawater, river water, sewage, industrial water, etc., as a heat source of a heat pump. CONSTITUTION:When heat source water 2 is guided to a heat pump heat exchanger 4, fine particles 3 which has larger specific weight than that of water and is surface-treated to enhance its separating properties from the water are fed to the exchanger 4 together with the water 2, and the particles 3 repeatedly collide within a heat transfer tube to flow, thereby cleaning in the tube. The particles 3 discharged from the exchanger 4 are recovered, and again fed to the exchanger 4 together with the water 2 in one cycle, and the cycle is repeated.

摘要： PURPOSE:To enable the increase of heat accumulating capacity of a plant which is provided with a heat accumulating tank for storing cool and/or hot water for regional cooling and heating by a method wherein water supply is possible only when water temperature pumped up from the heat accumulating tank or water temperature manufactured by a heat pump is superfluous. CONSTITUTION:In a heat accumulating tank 3, water flowing into a heat pump 1 mainly during night is adjusted in the volume by a flowrate control valve 5, stored cold at a manufactured cool water temperature of 1 deg.C, and after completion of night heat accumulation, the water temperature is returned to a normal value of 6 deg.C. As a volume of manufactured water by the heat pump 1 is substantially constant, an intake volume from the heat accumulated water volume, if a required quantity of water is determined by a user 2, is determined according to a prescribed formula based on a mixture ratio with an intake volume from a bypass line 17 from a detection result of a return water temperature and the heat accumulated water volume at that time, and at the same time, an absolute volume can be obtained. Then, opening degrees of a flowrate control valves 8 and 7 are adjusted based on these values, a part of the return water and the intake water from the heat accumulating tank 3 or manufactured water of the heat pump 1 are mixed and fed to the user 2.
