摘要： PURPOSE:To reduce a recirculating amount of solution and reduce a power of circulation of the solution by a method wherein a plurality of sets of absorption devices composed of a solution over-cooling means and an absorption device, and evaporators are provided, and the solution is sent in sequence to each of the devices and then the absorption is divided into some stages. CONSTITUTION:An absorption evaporator device of an absorption freezer is made such that three sets of absorption evaporators having absorption devices 1, 5, 9, evaporators 2, 6, 10, solution over-cooling air-cooled heat exchangers 3, 7, 11. and solution transporting pumps 4, 8, 12 by pipes 61 to 63 in an operative manner are provided, the devices operatively connected by he pipes, an air-cooled heat exchanger 13 for initially over-cooling condensed solution from a regenerator and a refrigerant circulation pump 23 for feeding refrigerant toward a load are arranged. The solution is sent in sequence to the absorption device, the absorption is divided into three stages, so that at the absorption device other the final stage shows a high concentration of solution, resulting in that an increased range of temperature up to its balanced temperature can be increased, a recirculating amount of solution can be reduced and a power for circulating the solution can be reduced. At the stage other the final stage of absorption, the concentration of the solution is high and a pressure difference in absorption is high and so a volume of the absorption device can be reduced.

摘要： PURPOSE:To utilize vapor pressure differential and turbulence heat transmission so as to further compactness of an absorption refrigeration machine by the repetition of a process wherein a cooling mean cools absorption solution to a lowest temperature line and then adiabatic absorption of the refrigerant vapor is effected up to an evaporator-inlet-pressure line. CONSTITUTION:The outlet for absorption solution in a high temperature regenerator 1 and the outlet in a low temperature regenerator 2 are connected to an outer cooling part 14e through heat exchanger 6, 7, to an inlet 13a of a vapor-absorption part 13, through the vapor-absorption part 13 to a solution circulator 11a, and then to an outer cooling part 14a. From the outer cooling part 14a the connection leads to an inlet 13b of the absorption part 13 so that the solution absorbs refrigerant vapor inside the absorption part 13 and falls. Gradually thinned absorption solution is made to circulate by a solution circulator 11b, sent to an outer cooling part 14b, and after cooling brought to an inlet 13c of the absorption part 13. After passage through a cooling part 14, absorption part 13, and circulator 11 thus in many cycles the connection finally leads from a solution circulator 11e to the high-temperature regenerator 1 and the low temperature regenerator 2.

摘要： PURPOSE:To provide a greater freedom of heat storage capacity by disposing a cooling heat exchanger and a heater in or around a first container and providing a separate tank having heating medium to recover the waste heat released in the cooling heat exchanger so that a part of the first container may be made open to allow its adaptation to an open system as well. CONSTITUTION:A heater 4 and a first heat exchanger 8 are disposed inside a first vessel 1V, and the first vessel 1V is submerged in the heat storage material (such as water) in a first tank 12. The heat exchanger 8 and the tank 12 act to maintain the heat storage material 13 around the vessel 1V at nearly a constant temperature. Because of this, the temperature which is obtained by causing a material 1M in the vessel 1V and a material 2M in the second vessel 2V to react becomes easier to maintain. By having the tank 12 separately from the heat exchanger 8, the freedom of thermal designing can be made greater. In case where the temperature of the material 1M and heat storage material 13 became too high, a valve 25 is opened to dump the heating medium in the heat exchanger 8 to lower the temperature by changing the closed system to an open system.

摘要： PURPOSE:To prevent destruction caused by the volume expansion or thermal impact of heat storage material by a method wherein the heat storage material is sealed in a baggy heat storage container and a plate of porous material which has elasticity in the vertical direction to its plane and is not subjected to buckling in the parallel direction to the plane at least under no load condition is immersed in the heat storage material. CONSTITUTION:A heat storage element 10 is constituted in such a manner that heat storage material 3 (for example, polyethyleneglycol, etc.) is put into the inside of a baggy flexible container 1 (for example, made of nylon, vinyl, etc.) and a porous material 2 (made of glass fiber non-woven cloth, etc.) is immersed in the material 3. The material 2 is hardly subjected to buckling when a load is applied in the parallel direction (Y-Y' direction) to its plane and has uniform elasticity when a force is applied in the vertical direction (X-X' direction) to the plane. When polyvinyl alcohol is used as the binder material, the impregnating ability of this glass fiber non-woven cloth is made remarkably larger. The destruction of the heat storage container caused by the stress generated by the volume expansion or thermal impact of the heat storage material is avoided by the elasticity of the porous material.

摘要： PURPOSE:To enable a heat accumulating material to smoothly emit heat even during vibration or turnover of a heat accumulating container, by a method wherein seed crystal is disposed to the peripheral edge part of a container, formed in a flat shape, in a manner to make contact with a heat accumulating material, and a drop preventing means and a heating means are provided. CONSTITUTION:A latent heat type heat accumulating material 2 is placed in a heat accumulating container 1a formed in a flat shape and is sealed by means of a seal part 6, and annular seed crystal 4 is formed in a peripheral edge part 3a of the heat accumulating part 1a located inside the seal part 6. A stopper 7 is situated so that the seed crystal 4 is prevented from collapsing. The stopper 7 is formed such that the surface and the back of the heat accumulating container 1a is partly hot-pressed. Even when the heat accumulating container 1a is brought into any orientation, the seed crystal 4 makes contact with the heat accumulating material 2 without fail, and the crystal of the heat accumulating material 2 is smoothly grown from a contact part. A cordform heater 9 is disposed in a position in the heat accumulating container 1a, i.e. to the central part of the outer surface of the heat accumulating container 1a, and is not disposed to the peripheral edge part 3a. This constitution, when, with a heater 9 energized, the heat accumulating material 2 in the heat accumulating container 1a is heated and dissolved, causes heating of the seed crystal 4 but prevents dissolving of the series crystal.
