Usage of the MATHCAD framework for energy saving simulation

Abstract

This study explores the use of energy savings technologies in timber production for wood housing construction. Methods applied were based on the creation of system of optimized regimes of drying of sawn timber was carried out in two stages: computing experiment with the tools of MathCAD and production experiment. The findings discovered the following tendency: however the minimum cost of energy is achieved at the minimum time of drying that is explained by an essential difference in the cost of thermal and electric energy. The regimes of steeples structure received by computer modeling allow receiving sawn timber that fully meets the requirements of the consumer without application of moisture treatment and the conditioning processing. The developed technique of formation of the steeples regimes of drying of sawn timber allows determining structure and sizes of parameters of the regime depending on the required quality of drying and energy costs on its carrying out. Calculations of technical and economic efficiency have shown that the total annual economic effect in more than 17 dollars per 1 m3 and it can be extended by including on power component. © 2018 CEUR-WS.
