摘要： An energy recovery device includes a plurality of heat exchangers connected in parallel with each other into which a plurality of heat sources flow, an expander for expanding a working medium, a dynamic power recovery unit, a condenser, a pump for sending the working medium which has flown out from the condenser to the plurality of heat exchangers, and a regulator for regulating inflow rates of the working medium flowing into the plurality of heat exchangers. The regulator regulates the inflow rates of the liquid phase working medium flowing into the plurality of respective heat exchangers such that a difference of temperatures or a difference of degrees of superheat of the gas phase working medium which has flown out from the plurality of respective heat exchangers falls within a certain range. Thereby, heat energy can be efficiently recovered from the plurality of heat sources having temperatures different from each other.
