Abstract
A sunlight heat utilized steam absorption chiller is provided with a generator which uses steam generated by sunlight heat as a heat source, an absorber, an evaporator, and a condenser, and has a heat exchanger for allowing heat exchange between a dilute solution flowing from the absorber to the generator and a strong solution flowing from the generator to the absorber. The chiller is provided with a burning heat source for generating steam, and either the steam generated by the burning heat source or the steam generated using sunlight heat can be used as the heat source for the generator. The chiller is provided with a steam drain heat recovery unit for allowing heat exchange between at least part of the dilute solution flowing from the absorber to the generator and a steam drain discharged from the generator so as to allow heat recovery from the steam drain.
