description: The topic of the graduate qualification work: "Calculation of the energy efficiency of internal engineering systems with heat recovery, depending on the use of freons". This work is devoted to the study of heat pump installations included in a water loop and the expansion of the existing methodology for calculating the annual energy consumption of such installations by adding the ability to select different refrigerants. Object of the study: internal engineering system with heat pumps included in a one heating water loop. When writing the work, such research methods were used as a review of literary sources of information, the collection of necessary data in previous researches, analysis, classification and systematization of data, comparison, description. Calculations were carried out showing the validity of the proposed extended methodology, as well as clearly demonstrating the reasonable choice of freon for a heat pumps. As a result of the work, the latest research of heat pumps in engineering systems was analyzed, the existing method for calculating the annual energy consumption of a building was expanded, and the most energy-efficient refrigerants were identified for operation in heat pump included in a one heating water loop.
