With reference to problems of heating and the ventilation indoors there are presented results of numerical investigation of three-dimensional stationary and nonstationary temperature fields in wallings with heat-conducting inhomogeneities, and also the results of mathematical modelling of processes natural and forced convection of air in limited volumes are reported. The laminar motion of air is described by means of the equations of the Navier-Stokes, turbulent - with the "κ-ε" model. The numerical integration of the equations is carried out with a method of control volume with using of developed iterative algorithms of the account. The calculations are based on homogeneous and nonuniform spatial grids.
