The greenhouses are used at agricultural enterprises producing crop products. It is proposed to utilize the heat of the ground in order to increase the high-quality energy supply of these facilities. Organic Rankine cycle is needed to get heat in the form of hot water, as well as electricity. Hot water can heat air in heaters and maintain the required air temperature in the greenhouses themselves. Electricity production is possible due to its generation by a micro-turbine or an expander. The most promising area is the conversion of the kinetic energy of freon into mechanical work in Tesla’s radial turbines. The article proposes a variant of the heat supply scheme of the greenhouse. The most effective technological solutions of putting into practice the organic Rankine cycle are shown.
