THERMAL ENERGY RECOVERY DEVICE AND START-UP METHOD OF THERMAL ENERGY RECOVERY DEVICE

摘要

A thermal energy recovery device includes a heater that evaporates a working medium by heat of a heat medium, an expander into which the working medium flowing out from the heater flows, a driving machine connected to the expander, a condenser that condenses the working medium flowing out from the expander by a cooling medium, a reservoir unit that reserves the working medium condensed in the condenser, a pump that feeds the working medium flowing out from the reservoir unit to the heater, a circulation flow passage of the working medium that connects the heater, the expander, the condenser, the reservoir unit, and the pump in this order, and a pump control unit that controls drive of the pump, and the pump control unit drives the pump after the heat medium is supplied to the heater and the cooling medium is supplied to the condenser.

主权项

1. A thermal energy recovery device comprising:
a heater that heats a working medium by heat of a heat medium; an expander into which the working medium flowing out from said heater flows; a power recovery machine connected to said expander; a condenser positioned on the upper side of said heater, said condenser condensing the working medium flowing out from said expander by a cooling medium; a reservoir unit positioned on the upper side of said heater, said reservoir unit reserving the working medium condensed in said condenser; a pump positioned on the upper side of said heater, said pump feeding the working medium flowing out from said reservoir unit to said heater; a circulation flow passage of the working medium that connects said heater, said expander, said condenser, said reservoir unit, and said pump in the above order; and a pump control unit that controls drive of said pump, wherein said pump control unit drives said pump after the heat medium is supplied to said heater, and the cooling medium is supplied to said condenser so that the working medium is reserved in said reservoir unit.
