High negative pressure limits dispersion of airborne contaminants in hospitals and renovation sites
Maintaining a high negative pressure in airborne infection isolation rooms of hospitals (over -10 Pa) and in renovation sites (over -5 Pa) effectively limits the dispersion of airborne contaminants and dust, a new study from ...
Intelligent flow sensor for demand-controlled ventilation
VTT Technical Research Centre of Finland and Fläkt Woods Oy have developed a flow sensor that enables ventilation to adapt to actual demand, thereby improving indoor air quality and energy efficiency. The flow control utilises ...
Hybrid 'eco-roof' design combines five existing energy-saving technologies into a single system
Scientists at the University of Malaya have designed a roof that can help address an environmental conflict: increasing demands for energy to increase living comfort versus a need to scale back fossil fuel use to address ...
Liquid breathing moves a step closer thanks to measurement study
Liquid ventilation –breathing a liquid instead of air – has long been the stuff of science fiction, and despite experimental clinical use, its potential for treating severe pulmonary or cardiac trauma, and use in deep ...
Sitting in traffic jams is officially bad for you
With millions of motorists in the UK set to hit the road for the bank holiday weekend, drivers have been urged to close windows and turn off fans while in traffic jams to avoid breathing in dangerously high levels of air ...
Ventilation through breathing windows
Centralised ventilation systems that exchange heat between the air inside and outside a building often come with a lot of silver-coloured pipes and shafts. By contrast, compact and decentralised ventilation systems, which ...
New air recovery system could save poultry farmers millions annually
One of the largest variable expenses in poultry production is heating the barns in which chickens and turkeys are housed. Now, a team of researchers and engineers from the University of Missouri have developed a waste-heat ...
Researchers patent a natural ventilation system of roofs that prevents heat build-up
Researchers at the Universitat Jaume I of Castellón have developed a modular ventilation system for pitched roofs that solves the problem of heat accumulation by solar radiation under the roofs without the need for refrigeration. ...
Sistine chapel dazzles after technological makeover
High above the altar in the Vatican's Sistine Chapel, the halo around Jesus Christ's head in Michelangelo's famous frescoes shines with a brighter glow, thanks to a revolutionary new lighting system.
