To suppress the generation of clinker so as to prevent the generation of a burning trouble, ceramic particlesare covered over a porous plateto form a fire bed. Woody pelletsare 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 sectionto 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.

Burning method of woody pellet and burning apparatus thereof

An air conditioner is provided that includes an exhaust heat recovery unit for recovering exhaust heat in a heat transfer medium, a heat transfer medium passage in which the heat transfer medium outputted from the exhaust heat recovery unit flows, an auxiliary heating device, heats the heat transfer medium, an absorption chiller driven by heat of the heat transfer medium, a refrigerant passage, through which a refrigerant outputted from the absorption chiller flows, an indoor unit to which the refrigerant is supplied through the refrigerant passage, a heat transfer medium temperature detector for detecting the temperature of the heat transfer medium flowing through the heat transfer medium passage, a refrigerant temperature detector for detecting the temperature of the refrigerant flowing through the refrigerant passage, and a control portion for controlling an operation of driving the auxiliary heating device.

Air conditioner

The air conditioner comprises heat transfer medium temperature adjusting device for adjusting the temperature of a heat transfer medium, an absorption chiller having as a heat source the heat transfer medium supplied from the heat transfer medium temperature adjusting device via a heat transfer medium line through which the heat transfer medium conducts, a valve provided in the heat transfer medium line , a by-pass line branching off from the valve , and an indoor unit supplied with a refrigerant from the absorption chiller or the heat transfer medium from the heat transfer medium temperature adjusting device via the by-pass line . Thereby, at the time of heating, the valve is switched to allow the heat transfer medium to pass through the by-pass line , so that the heat transfer medium can be directly supplied via the by-pass line to the indoor unit . Hence, in the heating operation, the devices such as pumps involving the operation of the absorption chiller can be stopped, so that the air conditioner can be improved in the energy saving.

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. Alternatively, the bellows-fin is vertically arranged so that one of the chambers defined by the bellows-fin is used as the burner combustion chamber and exhaust path in which gas flows vertically from a lower portion to an upper portion thereof whereas the diluted solution is dripped vertically from an upper portion to a lower portion of the other chamber to form liquid layer falling film to be boiled and evaporated to generate vapor refrigerant. Then the concentration solution is discharged from the lower portion of the chamber for circulation.

Absorption type refrigerator

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.

Heat exchange system

An air-cooled absorption air-conditioner comprising a high-temperature regenerator for heating diluted solution which has absorbed refrigerant, a separator for separating refrigerant vapor obtained by the high-temperature regenerator from the diluted solution, a condenser for condensing the refrigerant vapor into liquid refrigerant, an evaporator for vaporizing liquid refrigerant, cooling circulation heat medium by the effecting heat exchange between it and the above-mentioned liquid refrigerant vaporized and supplying the circulation heat medium thus cooled to a space to be cooled, an absorber for allowing the refrigerant vapor generated in the evaporator to be absorbed by the solution separated in the separator and removing the heat thereby generated by air-cooling, and a heat-medium-circulation pump for circulating the circulation heat medium, the circulation heat medium being heated using the refrigerant vapor generated in the evaporator and supplied to a space to be heated. The evaporator includes a circulation-heat-medium passage which is in contact with a liquid-refrigerant-evaporation surface of the evaporator, and refrigerant-vapor flow passage connected to the separator and in contact with the circulation-heat-medium flow passage through a heat-transfer surface. A valve is provided at least in that portion of said refrigerant-vapor flow passage where refrigerant flows from this passage to the separator.

Air-cooled absorption type cooling and heating apparatus

In an air-cooled absorption type cooling/heating water generating apparatus using a refrigerant and an absorbent solution and including a high-temperature regenerator, a separator, a low-temperature regenerator, an air-cooled condenser, an evaporator, an air-cooled absorber, a high-temperature solution heat exchanger, a low-temperature solution heat exchanger, a solution circulating pump and a refrigerant circulating pump, a constant flow rate control valve is disposed in a conduit connected between the high-temperature solution heat exchanger and the low-temperature regenerator so as to control the flow rate of the solution flowing through the conduit, and a pressure regulating valve is disposed in a conduit connected between the low-temperature regenerator and the condenser so as to regulate the internal pressure of the separator.

Air-cooled absorption type cooling/heating water generating apparatus

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.

Air-cooled absorption-type water cooling and heating apparatus

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.
