SUNLIGHT HEAT UTILIZED STEAM ABSORPTION CHILLER AND SUNLIGHT HEAT UTILIZATION SYSTEM

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.
