摘要:
PROBLEM TO BE SOLVED: To concentrate a dilute solution diluted by an absorber by either sunlight heat or a burning heat source and perform operation with good efficiency.SOLUTION: The sunlight heat utilized steam absorption chiller includes a regenerator 1 which uses steam generated by sunlight heat as a heat source, the absorber 6, an evaporator 5, and a condenser 4, and has a heat exchanger 10 for allowing heat exchange between a dilute solution flowing from the absorber to the regenerator and a concentrated solution flowing from the regenerator to the absorber. The chiller is provided with a means for generating steam by the burning heat source, and either the steam generated by the burning heat source or the steam generated using sunlight heat can be input as the heat source for the regenerator. The chiller is provided with a steam drain heat recovery unit 105 for allowing heat exchange between at least part of the dilute solution flowing from the absorber to the regenerator and a steam drain discharged from the regenerator to allow heat recovery from the steam drain.
摘要:
There is provided an absorption refrigerator comprising a liquid-film type plate heat exchanger structure, which is improved in terms of installation while maintaining the height of the refrigerator at a practical levels. In an absorption refrigerator utilizing a liquid-film type plate heat exchanger for an absorber (A), an evaporator (E), a regenerator (G) and a condenser (C), all the absorber, the evaporator, the regenerator and the condenser, each comprising the liquid-film type plate heat exchanger, are arranged in a horizontal direction. The evaporator, the absorber, the regenerator and the condenser are accommodated in a single can body (1), and the evaporator and the absorber, and the regenerator and the condenser are, respectively, accommodated in different chambers arranged in a lateral direction, which are divided by a partition wall (16) provided in the can body. The evaporator and the absorber, and the regenerator and the condenser may be, respectively, accommodated in different can bodies arranged in the lateral direction.
