The data presented in this article were the basis for the study reported in the research articles entitled "Evaluation of a two-sided windcatcher integrated with wing wall (as a new design) and comparison with a conventional windcatcher" (P. Nejat, J.K. Calautit, M.Z.A. Majid, B.R. Hughes, I. Zeynali, F. Jomehzadeh, 2016) [1] which presents the effect of wing wall on the air flow distribution u...

Routing under energy harvesting constraints is considered. A routing protocol based on Dijkstra’s global routing algorithm is proposed and evaluated. The protocol dynamically modifies routing trees based on available energy accumulated through energy harvesting. Channel-state information is gathered in typical indoor environments using two experimental setups; one with eight nodes and on-body a...

A very large schlieren optical system (2.3x2.9m field-of-view) and its applications in thermal airflow visualization, high-speed imaging of shock waves, and full-scale equipment studies are described. In order to have such a large field-of-view this is a lens-and-grid-type schlieren system using a very large grid as a light source, as first described at the 7 ISFV. It is currently the largest i...

This paper accentuate upon the application of Heating, Ventilation and Air-conditioning system in supporting the manufacture of quality pharmaceutical products. The HVAC system supply conditioned air to coveted areas of indoor surroundings to stimulate and maintain required temperature, humidity, ventilation and air-purity. The Good Manufacturing Practice for HVAC services embraces number of is...

This paper addresses the optimal design of residential ventilation systems in an apartment floor plan in Korea. The term “optimal design” refers to the selection of a ventilation method (mechanical, hybrid), type of heat recovery (total, sensible only), outdoor airflow rate, and the optimal sizing and location of supply diffusers/exhaust registers. Decision-making criteria include initial and o...

Draft is one of the most common complaints in the indoor environment. It may be caused by convective air currents along windows and other cold surfaces providing air movement in the occupied zone of heated spaces. The present paper comprises measurements of airflow characteristics (mean velocity, turbulence intenSity, energy spectra of the velocity fluctuations, etc.) in a wide range of spaces ...

This article addresses the problem of localising a static gas source in an indoor environment by a mobile robot. In contrast to previous works, the environment is not artificially ventilated to produce a strong unidirectional airflow. Here, the dominant transport mechanisms of gas molecules are turbulence and convection flow rather than diffusion, which results in a patchy, chaotically fluctuat...

CODYRUN is a multi-zone software integrating thermal building simulation, airflow, and pollutant transfer. A first question thus arose as to the integration of indoor lighting conditions into the simulation, leading to a new model calculating natural and artificial lighting. The results of this new daylighting module were then compared with results of other simulation codes and experimental cas...
