Optimization and modeling of thermal processes in stationary objects
Nemirovskaya V. V., Aleksandrova A.P. , Senikov A.M.
The article deals with optimization methods of thermal processes in life-support systems which service objects of different functional purposes, using mathematical modeling based on thermodynamic model of Professor A.A. Rymkevich. When creating a mathematical model uses simulation modeling, the essence of which lies in the fact that the process of functioning of a complex system is represented as an algorithm, which is implemented on a computer. The ways of solving the optimization problem is: the use of various air handling schemes (supply and exhaust direct-flow air handling, with recirculation air and heat recovery), energy-efficient equipment with (EC-motors), as well as day/night and summer/winter modes in the operation of heating, ventilation and air-conditioning systems. The use of recirculation air in ventilation systems is alternative way of saving with which you can re-use exhaust air and mixing it with fresh air. Heat recovery helps to reduce energy consumption through the use of emitted heat into the environment of exhaust air. The variants of the optimization criterion were presented by which it is possible to give a quantitative and qualitative assessment of the optimized life-support system.
