Abstract: The device has a heat storage tank (2) filled with a heat storage material (1) for storing heat delivered from the exterior, a heat exchange material (3) for the delivery and extraction of heat between the interior of the heat storage tank and the environment by an exchange of heat between the heat storage material and a heat transfer medium. The heat exchange material is arranged to perform a heat exchange between the heat storage material and a heat transfer medium. A natural convection suppression arrangement that suppresses the natural convection of the heat storage material is arranged in the outer region (2b) of the heat storage tank.

Abstract: A heat storage device comprises a heat storage tank 2 charged with a heat storage material 1 for storing the heat supplied from the outside, and a heat exchanger 3 for executing an injection and an extraction of heat between the inside of the storage tank 2 and the outside by the heat exchange between the heat storage material and a heat transfer medium. The heat exchanger 3 is disposed so as to execute a heat exchange between the central portion 2a in the heat storage tank 2 and the outside, and suppresses the natural convection of the heat storage material 1 of the outer portion 2b by, for example, dispersing a liquid-absorbent material 5 in the outer portion 2b surrounding the central portion in the heat storage tank 2, whereby reduces the influence of external environment on the central portion 2a in the heat storage tank, thereby suppressing the heat loss toward the outside.

Abstract: PROBLEM TO BE SOLVED: To obtain a heat accumulator in which the capacity of a hot region and a cold region can be altered quickly without supplying a significant thermal energy externally while accumulating heat and cold simultaneously. SOLUTION: Thermal insulation is imparted to the wall surface facing each region of a movable wall 2 for sectioning a thermal storage tank to be filled with a thermal storage material into a hot region and a cold region. Conduction holes 4a, 4b communicating with the respective regions provided on the wall surface are made through the movable wall 2 and a heat storage region 3 for taking in a part of the thermal storage material from these region is formed. A means for forming temperature hierarchy between heat and cold by suppressing convection of the thermal storage material flowing through the conduction holes is provided in the heat storage region 3.

Abstract: PROBLEM TO BE SOLVED: To provide a heat accumulator which does not lose much heat to the outside. SOLUTION: A heat accumulator is provided with a heat storage tank 2 packed with a heat storing material which stores heat given from the outside, and a heat exchanger 3 which performs heat injection and extraction between the tank 2 and the outside through the heat exchange between the heat storing material 1 and a heat carrier. The natural convection of the heat storing material 1 is suppressed in the peripheral section 2b of the tank 2 by piping the heat exchanger 3 so that heat exchange may occur between the central part 2a of the tank 2 and the outside, and scattering a polymeric absorbent material 5 in the peripheral section 2b.

Abstract: PROBLEM TO BE SOLVED: To heat transport low quality waste heat of low temperature (80 deg.C or below) relatively close to normal temperature being discharged as environmental load without requiring any power and to recover, utilize or remove the transported heat. SOLUTION: Heat carrier is circulated through an enclosed container type evaporator 2 having an ejection opening 9, a piping 5, a condenser 3 and a heat carrier storage tank 4. The evaporator 2 evaporates the heat carrier with heat absorbed externally to generate high pressure steam thus increasing inner pressure thereof. A pressure action valve 10 fixed to the ejection opening 9 is opened by the generated high pressure steam to eject the heat carrier 6 itself into the piping 5 thus carrying the heat carrier 6 through the piping 5.

Abstract: PROBLEM TO BE SOLVED: To obtain a heat transport system excellent in durability and operational stability in which isolation between a storage unit and an evaporator is enhanced by interconnecting a first tank for evaporating inner liquid with a second tank for delivering condensed liquid to the first tank through a pipe provided with a valve which passes gas freely but suppresses passage of liquid. SOLUTION: A pipe D interconnecting a storage unit 11 and an evaporator 12 is provided with an air purge valve allowing movement of gas from the evaporator 12 to the storage unit 11 but not allowing passage of liquid and one end of the interconnecting pipe D on the evaporator 12 is submerged below the liquid level. Heat carrier 19 in the evaporator 12 is heated with heat from a heat source 18 and when the liquid level in the interconnecting pipe D rises up to the air purge valve 1, it can not advance furthermore. As evaporation progresses in the evaporator 12, liquid state heat carrier 19 does not exist in the interconnecting pipe D and vapor state heat carrier 19 moves from the evaporator 12 through the air purge valve to the storage unit 11. Liquid state heat carrier 19 in the storage unit 11 falls freely through an interconnecting pipe A to flow into the evaporator 12.

Abstract: PROBLEM TO BE SOLVED: To provide a heat storage device to store heat at a plurality of temperature areas and reduce incurring of a heat loss to external environment and to provide a heat control method for this device. SOLUTION: A plurality of heat storage tank to store heat imparted from an external part and take out the heat are concentrically or coaxially arranged such that an inner heat storage tank 2a is surrounded with an outer heat storage tank 2b. The heat storage tanks 2a and 2b store heat such that temperature is increased or decreased from external environment toward the inside to store heat. This constitution performs storage of heat different with every heat storage tank in temperature, decreases a temperature difference between the heat storage temperature of the heat storage tank and external environment with the decrease of a distance between the heat storage tank and the outside, and reduces incurring of a heat loss from the heat storage tank to an external part.

Abstract: PURPOSE:To obtain a control characteristic with small error and make outer tank temerature follow inner tank temperature automatically and accurately by making the follow-up control operation of the outer tank temperature complete at constant time intervals and changing the openclose timing of a solenoid valve at each period. CONSTITUTION:The temperature difference between an outer tank 4 and an inner tank 3 which is measured with a temperature difference measuring device, is used as a controlled deviation, and a microcomputer 6 determines the follow-up manupilated variable with a follow-up manupilated variable calculation means. A solenoid valve opening time calculation means calculates the opening time of a solenoid valve 7 corresponding to the follow-up manupilated variable and send the result to an electromagnetic valve open-close control means. The solenoid valve open-close control means opens the solenoid valve 7 for the calculated opening time and supplies the outer tank with hot water from a hot water tank 9. The temperature in the hot water tank 9 is kept constant and the opening time of the solenoid valve 7 and the temperature variation in the outer tank controlled by supplying the hot water correspond to each other directly regardless of the elapsed time. Therefore, by doing the control operation periodically, the flowrate of the supplied hot water can be changed in the control operation and resultingly, an accurate control method is applicable.
