Abstract
On the basis of modern achievements in the effective replacement of fossil fuels in heat supply systems with heat from renewable and secondary sources, a heat pump technology for the production of bakery products using a two-stage vapor compression heat pump has been proposed. The modes of operation of the heat pump, which provide the preparation of heat carriers of different temperature potential for energy-efficient implementation of the technological process, have been established. In accordance with the methodology of exergy analysis, the influence of internal and external energy losses on the technological system of production of bakery products is considered. The total amount of internal exergy losses associated with the irreversibility of real processes included losses from a finite temperature difference as a result of recuperative heat exchange between material and heat flows; electromechanical losses for the operation of machine drives; losses in case of irreversible change in the properties of intermediate products; hydraulic losses caused by a sudden increase in the specific volume of the coolant when it enters from the pipeline into the working volumes of the apparatus. External losses are associated with the conditions for the interface of the system with the environment. The exergy analysis showed that the exergy efficiency for the technology of obtaining bakery products using PCHM is 16.35%, which is 5-7% higher than that of the known technologies. When a technological system passes into a state of equilibrium with the environment, this part of the energy is used in a useful way in the thermodynamic processes of the proposed technology.
