Two-dimensional mathematical model of energy-saving device for ventilation with cyclic veering of an air flow is developed. Results of calculations by two-dimensional model are compared with those obtained by one-dimensional model and with experimental data. It is shown that one-dimensional model [4] basically correctly describes the heat exchange in terms of temperature, averaged over cross-section. Parametrical researches are fulfilled by a method of numerical modelling to optimise the operating of the regenerative heat exchanger. Influence of parameters of the device on its energy efficiency is revealed.
