Night air conditioning of buildings by external air ventilation

The Air-Conditioning Energy Savings Achieved by Application of Time- Predicted Driven Night Ventilation

This paper analyses the influence of time-predicted night ventilation applied during the summer season on the total energy consumption of airconditioning system. Analysis has been made on the basis of a computer program for dynamic simulation of air-conditioned rooms thermal behavior. The program was developed at the Department for Thermal Engineering at the Faculty of Mechanical Engineering, U...

Ventilation and Air Distribution Systems in Buildings

The need of building occupants for ventilation has been recognized many centuries ago; however, since the early 1970s, ventilation systems for buildings and transport systems have considerably evolved. This was invigorated by researchers who demonstrated the requirements for buildings to provide comfort and good air quality indoors (e.g., Fanger, 1972; Fanger and Christensen, 1986; Fanger, 1988...

Distributed Control of Heating, Ventilation and Air Conditioning Systems in Smart Buildings

In this paper, the problem of distributed control of the heating, ventilation and air conditioning (HVAC) system in an energy-smart building is addressed. Using tools from game theory the interaction among several autonomous HVAC units is studied and simple learning dynamics based on trial-and-error learning are proposed to achieve equilibrium. In particular, it is shown that this algorithm rea...

Predictive control of multizone heating, ventilation and air-conditioning systems in non-residential buildings

In France, buildings account for a large part of the energy consumption and carbon emissions. Both are mainly due to Heating, Ventilation and Air-Conditioning (HVAC) systems. Because older, oversized or poorly maintained systems may be using more energy and costing more to operate than necessary, new management approaches are needed. In addition, energy efficiency can be improved in central hea...

Effects of Architectural Somatic Variables on Mixed Air Conditioning Systems’ Efficiency in Industrial Buildings
