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.
