Cooling control device for condenser

A cooling control device for a condenser in a Rankine cycle apparatus comprising:

• an evaporator for heating a liquid-phase working medium to produce a gaseous-phase working medium;
• an expander for converting heat energy of the gaseous-phase working medium, discharged from said evaporator, into mechanical energy;
• said condenser for cooling the gaseous-phase working medium, discharged from said expander, to convert the gaseous-phase working medium back to the liquid-phase working medium;
• a supply pump for supplying the liquid-phase working medium, discharged from said condenser, to said evaporator in a pressurized condition;
• first cooling means for cooling a gaseous-phase portion of said condenser;
• second cooling means for cooling a liquid-phase portion of said condenser, said second cooling means being operable independently of said first cooling means;
• pressure control means for adjusting a cooling efficiency of the gaseous-phase portion by driving said first cooling means in accordance with a detected pressure of the gaseous-phase portion, to thereby adjust the pressure within the gaseous-phase portion;
• temperature control means for adjusting a cooling efficiency of the liquid-phase portion by driving said second cooling means in accordance with a detected temperature of the liquid-phase portion, to thereby adjust the pressure within the liquid-phase portion;
• and
• said first and second cooling means being independently responsive to said pressure control means and said temperature control means, respectively.
