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.

摘要： To provide a hydrogen gas supply device with which pressure resistance of a filter that catches sulfur components contained in a hydrogen gas is improved. A hydrogen gas supply device for a hydrogen station includes a compression portion that compresses a hydrogen gas by reciprocating motion of a piston, in which a piston ring containing sulfur components is mounted on the piston, a filter arranged on the downstream side of the compression portion, the filter that catches sulfur components contained in the hydrogen gas, and a first pipe connecting the compression portion and the filter. The filter includes an element portion having activated carbon onto which the sulfur components contained in the hydrogen gas are absorbable, and a steel housing portion that houses the element portion, in which a gas introduction passage that communicates with the first pipe and guides the hydrogen gas to the element portion is formed.
