Abstract: To suppress the generation of clinker so as to prevent the generation of a burning trouble, ceramic particles 30 are covered over a porous plate 4 to form a fire bed 3. Woody pellets 31 are scattered on the fire bed and combustion air is ejected from the lower side of the porous plate so as to burn the pellets. At the time of discharging ash generated by the burning to a secondary combustion space on the downstream side together with an air current of the combustion air or combustion gas, the ceramic particle layers and the woody pellet layer are stirred by a stirring section 21, 22 to thereby break clinker of the combustion ash formed in the fire bed, whereby the growth of the clinker is suppressed and the generation of a burning trouble is prevented.

Abstract: An absorption type refrigerator including a generator having an improved heat-exchange efficiency and which is compact and economical. The generator is constructed using a heat-exchanger made up of a bellows-fin formed by consecutively bending a thin plate into a wave-like form and seal plates attached to ends of the bellows-fin for sealingly separating chambers disposed on opposite sides of the bellows-fin. In constructing the generator using the heat-exchanger, the bellows-fin is transversely arranged so that a lower chamber is used as a combustion chamber and an exhaust path for a burner whereas a diluted solution is introduced into an upper chamber and discharged therefrom for circulation after generating vapor refrigerant and being converted into concentration solution.

Abstract: In a heat exchange system such as an absorption refrigerator, a heat exchange element is disposed in at least one of a heat exchanger, a condenser, an evaporator, an absorber and a low-temperature regenerator. The heat exchange element has a bellows-fin formed into a wave-like shape by consecutively bending a thin plate, and sealing plate sealingly attached onto ends of the bellows-fin, for defining adjacent two chambers alternately in the heat exchanger or the like. The heating fluid and the fluid to be heated are heat-exchanged to each other through the thin plate of the bellows-fin defining respective chambers, so that contact area is increased to thereby extremely improve the heat exchange efficiency. Further, the heat exchange element can be manufactured with ease, to thereby decrease the production cost.

Abstract: Disclosed is an air-cooled absorption-type water cooling and heating apparatus, wherein, during a heating operation, the absorption heat generated when a condensed solution absorbs refrigerant vapor is imparted to circulated cold or hot water flowing through a first cold/hot water heat exchanger so as to convert the water into hot water, and condensation heat necessary for condensation of refrigerant vapor by a water heating device is supplied to circulated cold or hot water flowing through a second cold/hot water heat exchanger so as to convert said water into hot water for heating. At this time, since the refrigerant solution evaporates on an inner wall surface of a cylinder by absorbing the heat of the air, the heat obtained from the air is added to the heat obtained from the high-temperature regenerator, with the result that a heat pump effect can be obtained.

Abstract: An air-cooled absorption type water cooling/heating apparatus has a cooling circulation system including an evaporator in which a liquid refrigerant is evaporated so as to cool a heat exchanger leading to a cooling heat radiator, and a heating circulation system including a heat exchanger leading to a heating heat radiator and disposed in a separator in which the solution which has been thinned as a result of absorption of the refrigerant is heated and fractionated into refrigerant vapor and thick solution. In the heating mode of operation, the circulation passages for the solution and refrigerant are closed. This arrangement enables a heat source, which is used for heating the refrigerant and the absorption solution in the cooling mode of operation, to be used also in the heating mode of operation, so that the construction of the apparatus as a whole is made compact.
