摘要:
An arrangement of an evaporator, an absorber, a generator and a condensor within a shell of a single effect absorption type refrigerator or a multiple effect absorption type refrigerator, such as a double effect or triple effect type refrigerator. Positioned on opposite sides within the shell are an evaporator and a generator, and disposed therebetween are an absorber and a condensor. This arrangement presents an improved efficiency in terms of space to provide a compact type refrigerator.

A high temperature regenerator of an absorption type hot and cold water generator and an absorption type hot and cold water generator capable of preventing corrosion from occurring by preventing local overheating at the heat transfer surface of the high temperature regenerator and capable of being miniaturized. The high temperature regenerator includes an outer case, an inner case, a plurality of solution pipes, a burner, a solution flow-in pipe, and a gas/liquid separation plate. The inner case is inside the outer case, and a solution is kept between the cases, with the inner case being submerged within this solution. The burner is mounted on the side of the outer case in such a way that heat can be supplied through the inner case, with the inside of the inner case serving as a combustion chamber. A plurality of solution pipes, through which the upper and lower portions of the inner case are connected, are disposed downstream of the combustion chamber, and the inside of each of the solution pipes is filled with the solution. The horizontal cross section of each of the solution pipes is elliptical, and two or more of the solution pipes are disposed so that the straight line portions in the elliptical shape become parallel to each other. The sections between the solution pipes serve as a combustion gas passage.

The present invention is provided with an evaporator, a primary absorber, a plurality of generators, a condenser and a direct contact type heat exchanger which is provided with auxiliary evaporator-absorber stages in a plural set. These evaporator-absorber stages in a plural set are divided into a plurality of groups and connected so that a solution is sent from the final absorber stage of each group into each generator. By this construction, the solution in a first generator of a plurality of generators can be made to work at a lower level of temperature than usual.

摘要:
There is disclosed an absorption refrigerating machine in which evaporators as well as absorbers are arranged in a two-stage manner. A refrigerant, heated by a regenerator, is condensed by a condenser, and then is fed to a first evaporator. The refrigerant, produced in the first evaporator, is absorbed by a first absorber, formed integrally with the first evaporator, and is formed into an intermediate solution, and then is fed to a second absorber. The second absorber comprises a spray absorber which obviates the need for providing a heat-transfer pipe therein. The condensed refrigerant is supplied to a second evaporator, formed integrally with the second absorber, from a refrigerant tank formed at a lower portion of the condenser or at a lower portion of the first evaporator. The refrigerant, fed to the second evaporator, is absorbed by the solution sprayed in a supercooled condition in the second absorber, thereby producing a dilute solution. Part of the dilute solution, raised in temperature by absorbing the refrigerant, is returned to the first evaporator, and exchanges heat with liquid refrigerant, condensed in the condenser, to be cooled. The cooled dilute solution is again sprayed in the second absorber. The dilute solution in the second absorber is kept in a supercooled condition, and therefore the chilled water or brine, flowing through a heat-transfer pipe, provided in the second evaporator, can be kept to a low temperature under 0.degree. C.

An individual air conditioning system with an absorption chiller heater having a controllable capacity, with thermal input to a burner of a high temperature regenerator being controlled by on-off control or the like even if the load is low. The temperature of cooling water is controlled in accordance with a concentration of refrigerant in an absorber, so that the refrigerating capacity of the absorption chiller heater can be freely varied from 0% to 100% without the refrigerant being frozen.
