THE ENERGY PERFORMANCE MODEL OF VENTILATION SYSTEM - PART 2.

The paper deals with the energy efficiency of the ventilation systems (ventilation units) in different design alternatives (with heat recovery, without recovery, effective fans, etc...). The alternatives of operation of the ventilation system at intervals during the day and throughout the year are also presented. The calculation of the airflow was executed in accordance with laws and standards valid in the EU and Slovakia (EN 15251, EN 13779, etc.). A large potential for energy savings in the Slovak building generally, due to the fact that majority of the buildings were constructed before 1989, before first important requirements for energy performance and savings of building. This paper is part 2 and it is continuation of paper with the same title „The Energy Performance Model Of Ventilation System - Part 1„ [ABSTRACT FROM AUTHOR]
