Abstract:
1. A liquid-level-position control device for a condenser in a Rankine cycle apparatus comprising: an evaporator for converting a liquid-phase working medium into a gaseous-phase working medium using heat from a heat source; a condenser for cooling the gaseous-phase working medium for conversion back to the liquid-phase working medium; liquid-phase working medium supply means for supplying the liquid-phase working medium to said condenser; liquid-phase working medium discharge means for discharging the liquid-phase working medium to outside said condenser; and control means for setting a first reference liquid level position and a second reference liquid level position for said condenser, and performing control such that, when a position of the fluid level within said condenser is lower than said first reference liquid level position, the liquid-phase working medium is replenished to said condenser by said liquid-phase working medium supply means, while, when the position of the fluid level is higher than said second reference liquid level position, the liquid-phase working medium is discharged from said condenser by said liquid-phase working medium discharge means.
