In this study a series of parametric laboratory measurements were made of the velocitiesoutside, ve, and inside, vi, a full-scale louver positioned in a rectangular opening located in avertical wall forming part of a 1m x 1m x 2m deep model room.
Sharples S, Maghrabi A
This paper presents an experimental study of natural ventilation induced by combined forces of thermal buoyancy and opposing wind in a single-zone building.
Andersen A, Bjerre M, Chen Z D, Heiselberg P, Li Y
In 1998 the Dutch ventilation industry launched a new generation of domestic ventilation systems on the market with high efficiency heat recovery applying counter flow heat exchangers and DC fans.
Op't Veld P
In order to assess the real performances of different demand controlled ventilation (DCV)systems, two of them were installed in meeting rooms of an office building.The first system is controlled by movement detection on terminal units and has been
Bernard A-M, Blazy M, Lemaire M-C
This paper discusses how simplified thermal and ventilation tools could be used during thefeasibility study of buildings to demonstrate the advantages of natural and low energyventilation strategies.
Rufus S C, Kolokotroni M
This paper presents the results of ventilation measurements taken in a non-occupied one-storey dwelling situated in the countryside.
Loncour X, Wouters P
In this paper, the ventilation of a “crêpe” paper-processing workshop containing dryers, which generate a high thermal load, is considered. Displacement ventilation has been used for many years in industries with high thermal load.
Papakonstantinou K A, Kiranoudis C T, Markatos N C
Conventional models of building occupants' environmental preferences such as thermal comfort are used to give guidelines for the average environmental conditions that will satisfy large groups of people.
Matthews I W, Virk G S, Azzi D, Raja I A
The relative importance of ventilation in the energy balance of buildings has been increasing,as a consequence of control of heat exchanges through the envelope and internalgains.
Leal V, Maldonado E
The development of guidelines for performance based innovative mechanical ventilationsystems in residential and commercial buildings is included in the European Commissionproject TIPVENT Towards Improved Performances of Mechanical Ventilation Syst
Blomsterberg A
There has been a growing interest in the use of natural ventilation in buildings to supplement orreplace mechanical air supply systems.
Vrins E, Oomens E
Infiltration has traditionally been assumed to affect the energy load of a building byan amount equal to the product of the infiltration flow rate and the sensible enthalpydifference between inside and outside.
Buchanan C R, Sherman M H
The humidity of room air is a necessary influence of design under the aspects of thermalbehavior, technology and conservation.The moisture absorption in the walls through sorptive materials or dehumidification on thecold window surface by dew poin
Trogisch A, Franzke U
The Building Air Tightness is an important parameter on ventilation systems performanceand energy losses.Yet, the total amount of leakage is as important on performances as their effective positionin the room.Some calculations have been run accord
Bernard A-M, Lemaire M-C
The operation and performance of forced-air ventilation systems with the aid of a dynamic modeling and simulation computer program are presented.
Shah D J
This paper aims to identify major characteristics of hybrid ventilation systems, whereby a clear distinction is made between ventilation for Indoor Air Quality control and ventilation as part of a strategy for control of thermal comfort in summer.
Wouters P, Heijmans N, Delmotte C, Vandaele L
The paper presents results from a wider study into providing displacement ventilationin urban areas by taking air into buildings from the top without the use of fans.Results from large scale experimental work are given.
Gage S A, Ayres P, Axon J
The paper presents a short description of the measurement program and the data collected for the “SynergieHaus”-project initiated by PreussenElektra and partners (now merged to E.ON).
Maas A
Computational Fluid Dynamics (CFD) has been used to predict the indoor environment airflow and overall ventilation effectiveness of natural or mechanical air distribution systems.
Maghrabi A
Before starting to design an HVAC installation for treatment, supply and exhaust of air to and from a building the needs should be listed, transformed to requirements and their consequences analysed.
