    摘要: An absorption heat pump and controlling methods thereof for utilizing exhaust heat to obtain high- and low-temperature fluids. The absorption heat pump comprises: a regenerator 1 to which exhaust heat is supplied to evaporate and isolate a refrigerant from a refrigerant liquor; a condenser 2 for condensing refrigerant vapor generated by the regenerator 1; a first evaporator 3 in which refrigerant liquor supplied from the condenser 2 is heated by exhaust heat for evaporation; a first absorber 4 in which the refrigerant vapor evaporated in the first evaporator 3 is absorbed into an absorbent supplied from the regenerator 1; a second evaporator 5 in which refrigerant liquor supplied from the condenser 2 takes heat away from water for evaporation, the water flowing through a heat exchanger pipe 15A; and a second absorber 6 to which part of an absorbent returned from the first absorber 4 to the regenerator 1 is supplied so that the absorbent absorbs the refrigerant vapor evaporated in the second evaporator 5 before being returned to the regenerator 1. The absorption heat pump supplies hot water and chilled water through a hot water pipe 14 and a chilled water pipe 15, respectively. The amount of the cooling water supplied to the second absorber 6, the amount of the refrigerant liquor distributed in the second evaporator 5, and the like are controlled on the basis of the chilled water's temperature detected by a temperature sensor S1.

    摘要: A method of controlling an absorption type refrigerating apparatus comprising detecting the temperature of the regenerator, limiting the amount of heating in the regenerator for a first predetermined time after the temperature of the regenerator reaches a predetermined temperature, controlling the amount of heating in the regenerator in accordance with a load when the temperature of the regenerator after the passage of the first predetermined time is lower than the predetermined temperature, abnormally suspending the regenerator by distinguishing a normal rise in the temperature of the regenerator caused by a load fluctuation from a rise in the temperature of the regenerator caused by leakage in the apparatus or the like when the temperature of the regenerator reaches the predetermined temperature within a second predetermined time after the passage of the first predetermined time, thereby avoiding repetitions of operation, suspension or limited operation of the regenerator and suppressing the corrosion of the regenerator.

    摘要: A generator for an absorption refrigerator has heat transfer pipes within a shell main body, an absorbing solution injecting port and absorbing solution exhausting port. An absorbing solution exhausting port is provided which receives the absorbing solution flowing over a dam which is higher than the exhaust port on the absorbing solution injecting port side. A steam box is provided to cooperate with the absorbing solution exhausting port, which box has an opening above the top of the dam. The absorbing solution flowing in the main body injected from the injecting port (3) forms a closed type heat exchanger connected with an open type heat exchanger provided at the steam box into which the absorbing solution vaporizes as it flows over the dam (41) into the exhaust box (42).

    摘要: A multitubular heat exchanger used in a power plant is provided with a bundle of U-shaped heat transfer tubes and a vent tube. The vent tube is located between an upper portion and a lower portion of the bundle of U-shaped heat transfer tubes. A steam flow guide plate is located above a hole of the vent tube and below the upper portion of the bundle of U-shaped heat transfer tubes. The steam flow guide plate obstruct a downward steam flow from the upper portion of the bundle toward the vent tube.
