Greenhouse industry around the world is actively introducing innovative technology. The suggested way to improve the cost efficiency of greenhouses is to use power supply systems, including heat pumps. The technology of installation and its calculations of heat pumps is well determined at present and widely used for heating houses and other premises. The paper presents the analysis of application of heat pump, working in conjunction with a heat engine for energy supply of greenhouses. We selected gas-piston engine capacity 315 kW of the company “Zvezda-Energetika” and the heat pump capacity of 523 kW of the company “Menergy” in our study. The results are: energy savings compared with traditional energy supply system of the greenhouse if using only the heat pump is 25%; if using a gas engine with heat recovery is 32%; when combined gas engine and TNU to 60%.
