ORGANIC RANKINE CYCLE AND A CYCLE CONTROL METHOD THEREOF IN CONSIDERATION OF THE PRESSURE DROP OF A CONDENSER TO PREVENT THE REDUCTION OF EFFICIENCY

摘要

PURPOSE: An ORC(Organic Rankine Cycle) and a cycle control method of the ORC in consideration of the pressure drop of a condenser are provided to maintain the optimum operation of cycle by continuously monitoring the pressure drop and cycle efficiency of a condenser using a pressure sensor installed in the rear end of a turbine and a condensing tank.;CONSTITUTION: An ORC comprises an evaporator(10), a turbine(20), a condenser(30), and a pump(40). A preheater(11) and an overheater(12) are installed in the front and rear ends of the evaporator. A condensing tank(35) for storing condensate is installed behind the condenser. A control unit continuously monitors the pressure drop and cycle efficiency of the condenser and controls the temperature at the front end of the turbine.;COPYRIGHT KIPO 2012
