과열도 제어에 따른 20kW 해수온도차발전플랜트 성능평가

Abstract

To experiment 20kW OTEC, the closed-cycle type of OTEC was designed and manufactured. R32 (Difluoromethane, CH2F2) was used as the working fluid and a temperature of heat source and heat sink is 26°C, 5℃, respectively. The semi-welded type heat exchanger is applied for the evaporator and condenser and the cycle was designed for the gross power of 20kW. In this paper, system was tested to analyze the operation performance with respect to superheat. The test results can be considered as a basic data for the design of 1MW OTEC plant.e heat exchanger is applied for the evaporator and condenser and the cycle was designed for the gross power of 20kW.
