摘要： PURPOSE:To provide a method for producing a storage medium by using heavy oil ash as a raw material and to obtain a storage medium by this method. CONSTITUTION:Ammonium ion and sulfate ion of storage medium components contained in heavy oil ash are dissolved in water to give an aqueous solution of ammonium sulfate. The aqueous solution of ammonium sulfate is concentrated into an aqueous solution of an ammonium sulfate component having a melting point lower than ice and 40-80 Kcal heat of fusion. This is the method for producing the objective storage medium using heavy oil ash.

摘要： PURPOSE: To apply a cooling load required for performing a trial test operation of a vapor absorption type freezer 1 to this machine when a regional cooling and heating plant is test operated. CONSTITUTION: This plant comprises an imitation load heat exchanger 3 for increasing temperature through heat exchanging with vapor generated by a vapor generator 2 with cold water generated by a vapor absorption type freezer 1. Opening or closing valves 10, 11, 12, 13 are opened when a plant is test operated, hot water of which temperature is increased with the imitation load heat exchanger 3 is mixed with cold water returned back from a regional cooling load and then the mixed water is supplied to the vapor absorption type freezer 1 as a cooling load.

摘要： PURPOSE:To provide a low temperature latent heat accumulation system which can be applied to a facility of cold heat source for a cryogenic industry. CONSTITUTION:Cold heat generated by a brine chilling device 1 (a brine temperature is about -15 deg.C) is fed to a heat exchanger 4-1 within a heat accumulation tank 2 through a brine circuit 5-1. An inner side of the heat accumulation tank 2 is filled with heat accumulative material (water solution of ammonium sulfate) obtained by refining heavy oil ash of a fire plant, heat accumulative material 3 heat exchanged with the brine in the brine circuit 5-1 is condensed or solidified at about -15 deg.C so as to complete heat accumulating operation. In turn, cold heat accumulated in the heat accumulative tank 2 at night in this way is thermally radiated at daytime, only a thermal radiating operation is carried out from the heat accumulation tank 2. That is, the heat accumulating material (ammonium sulfate) condensed or solidified at night is gradually melted, brine in the brine circuit 5-2 is cooled under utilization of its melting heat (melting point is about -15 deg.C) and then cold heat is sent to a demand location.

摘要： PURPOSE:To provide a device in which waste heat in a spacing of an under- ground chamber is utilized, a rate of utilization of the waste heat of an engine is improved and a total COP is further improved. CONSTITUTION:A turbo heat pump driven by a driving device is mounted within a center A. The turbo heat pump is connected to a heat pump in an under- ground chamber B. In summer season, an absorption freezer is operated and in winter season, hot water heat exchanged with the waste heat is directly supplied into the under-ground spacing. In this type of under-ground waste heat utilization device, the driving device is a gas engine 5 and further the device is comprised of an absorption freezer 9 operated with cooling water of the gas engine 5 and an absorption freezer 7 operated with the discharged gas of the gas engine 5.

摘要： PURPOSE:To equally distribute ice to each of thermal storage tanks so as to effectively perform a large amount of thermal storage by providing a device for relieving supercooled water from the state of being supercooled in the process of delivering to the respective thermal storage tanks the supercooled water transferred by transfer piping. CONSTITUTION:Cooling water is sent from each of a large number of thermal storage tanks 3 provided in order to increase the amount of heat storage to a supercooling device 1 through supply pipes 6 by means of a cooling water circulating pump 5, and is cooled in the supercooling device 1 by use of an external cold heat source to become supercooled water of a temperature not higher than 0 deg.C and not lower than -4 deg.C. The supercooled water 2 flows through a header 7 and is sent through distribution parts 10 and branching pipes 8 to each of the thermal storage tanks 3. The header 7 is extended to an area above the thermal storage tanks 3 provided farthest from the supercooling device 1, and the rear end of the header 7 is provided with an elbow 9 connected to the branching pipe 8 so as to transfer the supercooled water 2 to the thermal storage tanks 3. The supercooled water 2 is made to fall onto collision plates 4 provided as a device for relieving the supercooled water from the state of being supercooled. Thus, collision is given to the supercooled water so that part of the supercooled water changes into ice to form sherbet-like ice 11 in the thermal storage tanks 3.

摘要： PURPOSE:To form such a state that return water flows strongly in an ice heat- accumulating tank for a long time without flowing quickly to the side of expelling, by providing the jet of a cold-water return pipe at an upper underwater part in the ice heat-accumulating tank, pointing to horizontal direction. CONSTITUTION:The jet of a cold-water return pipe 5a is located at the upper part under a waterlevel 2, pointing to almost horizontal direction at one of the walls of an ice heat-accumulating tank 1. In this way, the cold-water return pipe 5a horizontally injects a jet stream 6 consisting of return water, pointing to ice lumps 3 in the ice heat-accumulating tank 1. The heat of the jet stream 6 is exchanged in the ice lumps 3 and melts the ice lumps 3. At the same time, the jet stream 6 peels the ice lumps 3 from the walls and takes the ice lumps 3 to pieces in the limits where the jet stream 6 diffuses. Since the jet stream with a higher temperature is in direct contact with the ice lumps, at the part with max. temperature difference, the jet stream effectively receives the latent heat of ice. Furthermore, since the jet injects the jet stream horizontally, an area where the jet stream is in contact with the ice lumps lengthens and since the jet stream takes the ice lumps in pieces, the contact area of the ice to water increases. In this way, the efficiency of heat accumulation is sharply improved.
