The aim of the research is to work out the method of work process numerical computation and to design an outline of power equipment jet-lowering thermo transformer prototype for effective heat supply systems. Methods of research are theoretical methods (thermodynamic analysis, thermal physic and mathematical modeling) and computational experiment. On the basis of the thermodynamic analysis, a new lowering thermo transformer's combination cycle was worked out, which provides effective conversion of input energy (mainly by way of heat, fuel) in the flow heat supply system coolant with the required temperature level ( 50…90 °C). The method and lowering thermo transformer work process computational investigation program, on the basis of which multivariate calculations were made, was prepared and tested. Relying on the calculated research the optimal characteristics area for proposed heat supply system and operating out parameters area, which correspond to maximum conversion value and exergic effectiveness were determined; the comparative measures of investigated thermo transformer's main parameters on various working agents in the range of operating modes as heat pump or refrigerating unit were obtained. On the basis of the data about thermo transformer's cycle optimal characteristics the following equipment was designed: liquid-vapor jet compressor, condenser, and condensate after cooler, evaporator, separator, Freon heater, water heating boiler. The results can be used in various fields of economy and society: in heat-and-power engineering and industrial heating engineering, in municipal economy etc. Product Description popup.authors Антонова Лідія Михайлівна Арсеньєв Вячеслав Михайлович Буянов Сергій Васильович Ванєєв Сергій Михайлович Вертепова Олена Олександрівна Казбан Олена Вікторівна Кобильченко Дар'я Олександрівна Лобова Ганна Сергіївна Мерзляков Юрій Сергійович Прокопов Максим Геннадійович Проценко Михайло Ігоревич Шарапов Сергій Олегович popup.nrat_date 2020-04-02 Close
