Purpose of the study: creation of a design model for an indirect heating boiler, taking into account the influence of internal structural materials. Research methods: idealization, formalization, modeling. As a result of the work, a design model of an indirect heating boiler was compiled with the possibility of taking into account the thermophysical characteristics of internal structural elements. This model was applied on a two-storey residential building with a total area of 218.69 m2. Based on the results obtained, it was concluded that accounting for internal structural materials affects the parameters of an indirect heating boiler at a charge time of up to 4 hours for the exergy efficiency and up to 6 hours for the temperatures of the heat storage material in the tank and the coolant at the outlet of the indirect heating boiler. This design model makes it possible to take into account in the calculations of indirect heating boilers the influence of the thermophysical characteristics of internal structural materials on the output parameters. The use of this model will increase the accuracy of calculations and improve the selection of suitable indirect heating boilers. |
