conditions of the system. In this section, isobutane is used as the working medium, and the optimal te and △tcw are studied at a fixed heat source inlet temperature tgw of 120 °C, the condensing... temperature te is 76 °C and the temperature difference of cooling water △tcw is 10 °C, the net power output has a maximum value of 12.33 kW. Figure 4 illustrates that thermal efficiency ηth changes......
