In traditional condensers of combined heat and power (CHP) plants, water is used, which is discharged into the environment and creates environmental stress. It is proposed to cool the steam by air or freon. The basic schemes of CHP condensers operating on compressed air and freon are given. A comparative calculation of the condenser operating on water, air and freon was carried out. Analysis of the results shows the effectiveness of air, and freon compared to water. The advantage of freon is that it circulates in the heat exchanger, forming a closed system. At decreasing the temperature difference at the inlet and outlet to the condenser, the heat transfer coefficient of freon is higher than that of air.
