This paper presents a new simplified method to measure the air entrainment ratio of an active chilled beam or induction unit.
Mika Ruponen and John A. Tinker
The suction cylinder described in this paper is a device to increase the ventilation flow rate, especially in naturally ventilated buildings. Outdoor wind is the driving force.
J. Guha and S. Holmberg
An energy and cost analysis has been performed which compared a dedicated outdoor air system (DOAS) with chilled radiant cooling panel (CRCP), designed for an official building located in the hot and humid climate of Chennai, India, and an existin

A formulation to analyze ventilation duct system airflows employing, as the basic unknowns, the flow rates in the channel sections and the static pressures at the channel section ends is presented.
Eero-Matti Salonen and Rauno Holopainen
In this study, the measured and predicted air distribution of an active chilled beam in a typical office room is described.
Guangyu Cao, Jarek Kurnitski, Panu Mustakallio and Olli Seppänen
This paper presents the results of tests on the two-zone airflow pattern that forms in a room with displacement ventilation under conditions of various heat sources and airflow rates.
Z. Trzeciakiewicz
The present work contains the details of an investigation of air diffusion and comfort issues of an isolation room of a hospital. Two types of cases have been chosen for a unidirectional ventilation system of the isolation room i.e.
Rajeev Kumar, Ravi Kumar and Akhilesh Gupta
CFD modelling can be used in the design of ventilation systems. However, simplifications in room airflow models may lead to errors and discrepancies between predictions and reality.
Barbara Lipska
In the Island city of Mumbai, the Suburban Railway System operates 2500 EMU trains each of 9 or 12 cars and 6.3 millions passengers commute per day. It is considered to be the lifeline of the city.
P.C. Sehgal, A.K. Malhotra and Alok Kapoor
Desiccant cooling is a potentially environmentally friendly technology which can be used to cool buildings without the use of traditional refrigerants. We have studied the operation of a desiccant cooling system in France.
Chadi Maalouf, Etienne Wurtz and Laurent Mora
Previous research has shown that air movement has a significant influence on humans’ thermal comfort.
Wigö H.
The effectiveness of various methods for saving energy and improving the indoor environment in buildings depends upon the building conditions under which those methods are applied.
Takao Sawachi, Shigeki Nishizawa, Hiromi Habara and Hisashi Miura
This paper presents an evaluation of the local thermal discomfort level in a classroom equipped with cross ventilation, for a typical moderate summer day in Portugal.
Eusébio Z. E. Conceição, Mª. Manuela J. R. Lúcio, Vitor D. S. R. Vicente and Vítor C. T. Rosão
The capability of HVAC systems is of interest when contracting specific function criteria such as room temperature. The probability of maintaining the criteria reflects the risk the building contractor will take when giving guarantees.
Myrefelt S.
Earth heat exchange (EHX) through buried horizontal air ducts (EHXair-hor) can be an effective passive/hybrid system to reduce heating and cooling loads in temperate climate zones.
Grosso M and Raimondo L.
Active thermal mass strategies can be used to enhance the performance of thermal mass through integration with the heating, ventilation and air conditioning (HVAC) systems.
D.J. Warwick, A.J. Cripps and M. Kolokotroni
This paper addresses the applicability of passive and low energy cooling technologies in the Czech Republic.
Lain M, Zmrhal V and Hensen JLM.
It is difficult to design a naturally ventilated indoor environment because there is insufficient knowledge to evaluate the effect of the natural ventilation space quantitatively. Especially, natural ventilation rate is not yet fully understood.
Nishizawa S, Sawachi T, Habara H and Seto H.
Age-of-air is a technique for evaluating ventilation that has been actively used for over 20 years.
Max H. Sherman
The rationale of an advanced natural ventilation system should be to control airflows and air temperature during winter, and to avoid unnecessary energy losses and local draught, while maintaining an adequate ventilation rate.
Marco Simonetti and Gian Vincenzo Fracastoro
