description: The topic of the final qualifying work: "Computational study of the influence of non-design parameters on the operation of a heating system with elevator mixing". The calculated study of the influence of the parameters of the heating system with elevator mixing on its operation was carried out. The basic mode for comparison is the calculated parameters of the heating system: the temperatures of the direct and reverse mains water and the heating system, the mixing coefficient, the room temperature. The history of the use of elevator units in heating systems, as well as methods of regulating seasonal heat load, is considered. For the classical scheme of the elevator node, the derivation of its pressure characteristics is given based on the solution of a system of equations in the form of conservation laws for flows. The obtained characteristic is compared with its known forms. The influence of hydraulic resistance in the heating system circuit and in the mixing line on all the characteristics of the heating system is investigated: the mixing coefficient, the temperatures of the direct and return water of the heating system, the temperature of the premises, the power of the heating system. The quantitative change of all parameters of the heating system in case of deviation from the design values of the available pressure at the heating point, the temperature of the direct mains water, the diameter of the nozzle of the elevator unit, the calculated outdoor temperature, the calculated room temperature is determined. The results obtained can be used in explaining the actual operating modes and in organizing the commissioning of heating systems with elevator mixing.
