THERMAL ENERGY RECOVERY DEVICE

摘要

A thermal energy recovery device of the present invention includes a heater that evaporates a working medium by a heat medium, an expander into which the working medium flowing out from the heater flows, a power generator that recovers expansion energy of the working medium expanded in the expander, a condenser of a condensing unit that condenses the working medium flowing out from the expander, and a pump that feeds the working medium condensed in the condenser to the heater. A connection portion between the condenser and the pump has a connection end portion connected to an inflow port of the pump, a bent portion bent upward from the connection end portion, and a standing portion extending upward from the bent portion so that the working medium in a gas phase is suppressed from coming into the pump even in an environment where vibration is generated.

主权项

1. A thermal energy recovery device comprising:
a heater that heats a working medium by heat exchange between a heat medium and the working medium; an expander into which the working medium flowing out from said heater flows; a power recovery machine connected to said expander, said power recovery machine recovering power of said expander; a condensing unit positioned on the upper side of said heater, said condensing unit condensing the working medium flowing out from said expander; and a pump positioned on the lower side of said condensing unit, said pump feeding the working medium condensed in said condensing unit to said heater, wherein a connection portion connecting said condensing unit and said pump has a connection end portion connected to an inflow port of said pump, a bent portion bent upward from said connection end portion, and a standing portion extending upward from said bent portion.
