MODELING OF MECHANICAL VENTILATION SYSTEMS IN BUILDINGS USING ENERGYPLUS SOFTWARE

Abstract

In the modern world today, the great amount of the total energy consumption is related to the building. Therefore, research and development of methods for improving energy efficiency in buildings are very important. A significant part of energy consumption in buildings relates to building ventilation. The primary functions of mechanical ventilation systems are delivering fresh air to people in the inside of building areas, removal of contaminated air from the premises, and support of general feeling of thermal comfort in buildings. In such away, in recent years, special attention is paid to the modeling of mechanical ventilation systems in buildings, in order to reduce energy costs by using heat recovery heat exchangers. Systems can be modeled using the required number of air changes per hour in a room, or using a given air mass flow. This paper presents a method of modeling of mechanical ventilation systems in buildings by using software EnergyPlus. One illustrative example is provided.
