Objectives:

The aim of this module is providing students with the necessary background for the design of plants with mass and heat transfer components. The acquired notions are utilized for the design of building heating plants with reference to the more recent plant technologies, to the national and international Standards on the design and evaluation of the thermal performance of buildings and building components.

Requirements:

none

Acquired skills:

The use and the understanding of the appropriate terminology in the design of heating plants;
The evaluation of the building thermal losses;
The evaluation of the energy requirements of heating plants according to the Standards;
The design of the thermal insulation in civil, commercial and industrial buildings;
The dimensioning of heating plants with radiators, fan-coils and radiant panels;
The heating plant component selection;
The design of air heating plants;
The design of solar collector plants;
The estimation of the risk of interstitial condensation in building components.
