Detailed description of topics:

·         Introduction indoor climate: objectives, heating, ventilating, air conditioning (HVAC).

·         Characteristics of humidity. The Mollier diagram giving the relations between absolute humidity, relative humidity and enthalpy, is discussed.

·         Thermal comfort. Various definitions of comfort are given. The comfort model of Fanger and its use as a design tool are demonstrated.

·         Outdoor climate as disturbing factor; physical and statistical properties of solar radiation. Temperature, humidity and wind.

·         Heating and cooling loads in buildings. The thermal response of the building in outdoor climate, internal heat sources. Calculation of capacities of HVAC-installations.

·         HVAC systems and their applications. When, what to apply.

·         Design of transport of air and water (Ducts and piping).

·         Air flow patterns in air conditioned confined spaces: calculation methods are discussed and an introduction of the computational fluid dynamic computer codes is given.

Course material:

·         Indoor Climate A (wb4412)

·         Calculation of heating, cooling load and temperature exceeding.
