RESEARCH OF STATIONARY OPERATING MODES OF THERMOELECTRIC HEATEXCHANGE DEVICES

The necessity of detailed research, relevant consume cal semiconductor heat transfer devices. Distinctive features of thermoelectric devices flow type caused by the change of temperature of streams of coolant along the junctions of termoelectromotoare are identified. Differential equations systems determining the temperature change of the coolants, excluding from them the values of the temperatures of the junctions are used. A mathematical model for parallel flow and counter-flow thermoelectric heat pumps has been constuctucted. A mathematical model of a thermoelectric heat exchanger without any flows of heat in the gaps between the semiconductors has been developed. The cooled and heated liquids temperature dependences at the outlet of the heat exchanger from the heat transfer coefficient to the inner surface of the heat exchanger and reduced heat transfer coefficient from the outer surface of the heat exchanger have been constucted. It is proved that for the same values of heat transfer coefficient to the inner surface of the heat exchanger and reduced heat transfer coefficient from the outer surface of the heat exchanger reducing the temperature of fluid to be cooled significantly more than the increase in the temperature of the heated liquid. The main results obtained by the model are summarized. The analysis is carried out using MathCAD

SOFTWARE APPLICATION FOR CALCULATING MODELS FORECASTING INNOVATIVE DEVELOPMENT OF INDUSTRIES

Objectives. The article is devoted to the development of a software application that allows you to automate methods for collecting and processing information, as well as perform time-consuming analytical calculations. Embarcadero C ++ Builder XE, a visual object-oriented programming language, was used to implement a software application. The software being developed is created to solve the following tasks: a comparative analysis of innovative development indicators for the selected years; selection of a projected indicator, building a regression model; making a forecast with a lead time of 3; determination of the confidence interval; the formation of a graphical display of observable and calculated values, the selected indicator of innovative development.Method. In a software application, formalized methods were used as a mathematical model, one of which is multiple regression. Regression analysis consists in defining an analytical expression of a relationship in which a change in a single quantity, called a dependent or productive attribute, is due to the influence of one or several independent quantities (factors).Result. With the help of the developed software product, you can not only automate time-consuming methods of collecting and processing information, but also per-form complex analytical calculations using the multiple regression method.Conclusion. Embarcadero C ++ Builder XE is by far the latest state-of-the-art technology and C ++ programming environment. With C ++ Builder, XE has become faster to do the job of creating high-quality applications for Windows-based applications, due to the rapid writing of code, new tools and components
