    摘要： 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.

    摘要： In an absorption air-conditioning system, in order to immediately stop indoor air-conditions by a stop signal of the indoor air-conditioners and improve characteristics for activating the system , such as, by effecting re-activation at a relatively short time interval after stopping the operation of the system, when the last one of the operating indoor air-conditioners is stopped, a stop signal is sent to a control device from a controller for the indoor air-conditioner, and in response to this signal, the control device effects the control of stopping a burner, a cooling medium circulating pump, a cooling water pump and a cold/hot water, pump. A solution circulating pump, however, continues operating and the solution, while kept at a high concentration, is circulated through an absorber, a high-temperature regenerator and a low-temperature regenerator. During this time, an indicated value of a temperature sensor gradually decreases, and when this value reaches a predetermined temperature, the control device switches a control valve from its open condition to its closed condition and another control valve from its closed condition to its open condition, and also activates the cooling medium circulating pump again to feed a cooling medium to a solution reservoir at a lower portion of the absorber, thereby diluting the solution.

    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.
