The article considers the problem of increasing the energy efficiency of heat supply of livestock complexes by introducing heat pump units of the “air-to-water” type. Modern means of energy supply of livestock farms are studied, the main shortcomings of traditional hot water supply systems from an electric boiler are identified, and alternative solutions are proposed using renewable energy sources - a heat pump unit of the “air-to-water” type using the propane refrigerant R290. In the process of the study, experimental studies and analysis of electricity consumption by traditional water heating devices were conducted. The effectiveness of implementing a heat pump to replace an electric boiler was assessed. The transformation coefficient of the heat pump unit by months of the year and the average annual one were analyzed. It was found that the heat pump provides stable efficiency throughout the year - from COP 2.76 in the winter months to over 5.5 in the summer. It was established that the use of heat pump technology allows reducing annual electricity costs by almost 5 times, providing significant cost savings. Calculations showed that the payback period of the project is about 2 to 5 years, which confirms its economic feasibility. It was estimated how the payback period of the project changes due to changes in the electricity tariff and the cost of operating and additional costs for servicing the heat pump unit. It was found that a higher electricity tariff contributes to a decrease in the payback period of the project. The use of propane R290 refrigerant in the heat pump unit to replace freon ensures the environmental safety of the technology, since it has a low global warming potential (GWP). It is proven that heat pump units contribute to increasing energy efficiency, reducing dependence on fossil energy resources and reducing the negative impact on the environment. The results of the study indicate the feasibility of large-scale implementation of heat pump systems in agricultural enterprises to increase the competitiveness of the industry and sustainable development of the agro-industrial sector.
