This paper presents a new simplified method to measure the air entrainment ratio of an active chilled beam or induction unit. The method uses a single…
The suction cylinder described in this paper is a device to increase the ventilation flow rate, especially in naturally ventilated buildings. Outdoor wind…
An energy and cost analysis has been performed which compared a dedicated outdoor air system (DOAS) with chilled radiant cooling panel (CRCP), designed for…
A formulation to analyze ventilation duct system airflows employing, as the basic unknowns, the flow rates in the channel sections and the static pressures…
In this study, the measured and predicted air distribution of an active chilled beam in a typical office room is described. A free convection model was…
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…
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…
CFD modelling can be used in the design of ventilation systems. However, simplifications in room airflow models may lead to errors and discrepancies between…
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…
Desiccant cooling is a potentially environmentally friendly technology which can be used to cool buildings without the use of traditional refrigerants. We…
Previous research has shown that air movement has a significant influence on humans’ thermal comfort. For persons feeling cool, air movement tends to be…
The effectiveness of various methods for saving energy and improving the indoor environment in buildings depends upon the building conditions under which…
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…
The capability of HVAC systems is of interest when contracting specific function criteria such as room temperature. The probability of maintaining the…
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…
Active thermal mass strategies can be used to enhance the performance of thermal mass through integration with the heating, ventilation and air conditioning…
This paper addresses the applicability of passive and low energy cooling technologies in the Czech Republic. The main research methods are climate analysis…
It is difficult to design a naturally ventilated indoor environment because there is insufficient knowledge to evaluate the effect of the natural…
Age-of-air is a technique for evaluating ventilation that has been actively used for over 20 years. Age-of-air quantifies the time it takes for an elemental…
The rationale of an advanced natural ventilation system should be to control airflows and air temperature during winter, and to avoid unnecessary energy…
