Abstract
Currently, the use of heat pumps in the Republic of Kazakhstan is becoming popular. However, there is no introduction of low-potential thermal resources from renewable sources together with the use of heat pumps, which is important in the area of energy conservation and also deemed nature-friendly for the country. The purpose of this work to form a mathematical model of the optimal choice of the working units and calculation of thermodynamic parameters of a heat pump installation, taking into account the design and climatic conditions of the Kostanay region situated in the northern region of Kazakhstan. The conditions of efficiency and the choice of a specific source of thermal energy are considered, which depends on climatic conditions, especially if the source of heat extraction is atmospheric air and earth. The mathematical model of the heat pump unit is formed by studying arithmetic relations in the function of temperature indicators of external and internal environments, which characterizes its effective use in the climatic conditions of the Northern region of Kazakhstan. Based on the developed algorithm of the model’s calculations of heat consumption, the thermal power of the heat pump was made.
