Abstract
Calculations of exergy (heat loss) were carried out on different types of combined solar collectors and heat pump systems to determine the most appropriate version of the heating and hot water needs in Kazakhstan in harsh climatic conditions. To achieve this goal, a mathematical model was applied, representing a set of formulas for the sequential elementary calculation of temperature data from a solar heating system. An algorithm was developed to calculate the heat loss of both the solar collector system and the solar-assisted heat pump. The significance and importance of the achieved results is high, since, the developed and used algorithm allows detecting inefficient components of the solar heating system. In cold climatic conditions, the exterior performance of the solar collector ranges from 5-27%. Capacitor efficiency ranges between 9-15%. The least effective is the compressor, the exergy values of which vary within 10-88%.
