Anotace
Theoretical fundamentals of heat and moisture transfer and their application in environmental engineering.
· Stationary and non-stationary heat conduction.
· Heat transfer by convection, classification of heat convection cases, natural convection currents in enclosed
spaces.
· Heat transfer modelling, similitude criteria, criterion equations.
· Heat transfer by radiation, spectral and directional properties of surfaces and heat radiation.
· Heat flow in an enclosed system of diffuse grey surfaces, mean radiant temperature in a room.
· Solar radiation, direct and diffuse irradiation of the building, radiation of the Earth and building towards the sky.
· Combined heat transfer – heat transfer through wall, heat loss from piping and heat storage tanks.
· Outdoor climatic conditions, design conditions, characteristic curves.
· Heat transfer through opaque building structures, sol-air temperature, heat accumulation effect.
· Heat transfer through translucent building structures, thermal and optical properties of glazing.
· Moisture transfer by diffusion and convection, similitude criteria, criterion equations.
· Moisture transfer in air and building structures.
· Combined heat and moisture transfer, analogy between heat and mass transfer by diffusion and convection, wetbulb
thermometer temperature.
