Results of microclimate modeling in living quarters with different types of heaters

Energy efficiency and thermal protection of buildings

The features of microclimate creation in living quarters where outside air inflow comes through ventilation valves are studied with respect to different types of heat appliances (convection heaters and radiators). The numerical simulation was used. Hydrodynamic equations solving taken with initial and boundary conditions allowed us to obtain information about temperature distribution and air speed in the studied volume. The solution was performed for the nonstationary problem. The study results provide an estimation of temporal patterns of temperature changes and air speed in different zones of heated room with radiators and convection heaters in use. It was concluded that convection heaters were preferable to radiators since their convection stream was more powerful which allowed creating stable and uniform temperature and velocity fields in room’s volume given open ventilation valves.
