Implementation and research of operating parameters of energy-efficient engineering systems with a single circuit of heat engines

The paper studies the performance of a modernized recuperation system for hot vapors of refrigerant freon vapor, which increases the share of use of heat that is not usefully used and released into the atmosphere by air condensers in an air heating system in order to increase their energy efficiency and optimize operating costs. To analyze the calculated and actual values, a research stand was developed and implemented, the data from which is continuously recorded and stored on a personal computer. Based on the analysis of the recorded data, the dependence of the temperature of the coolant at the outlet of the system on the outside air temperature was obtained, and the parameters that must be maintained in order to achieve maximum efficiency were identified. It is shown that after the modernization of the system, the use of a recuperation system in the air heating system can reduce operating costs by 2.4 million rubles. per year and reduce the negative impact on the environment by reducing thermal emissions by 1372140 kW per year
