Application Fire dampers prevent fire from spreading in air conditioning and ventilation installations. They are installed at crossings of ventilating ducts through partition walls and ceilings which divide a building into fire compartments. Description Fire dampers consist of housing made of galvan[r]

with higher inspiratory concentration of CO2, which decreased at increasing flow rates [5].Similar findings were reported in a bench and healthy volunteers study with an increase ininspired concentration of CO2 when the gas flow rate was reduced below 30 l/min. It isnoteworthy that the study also sh[r]
Ventilating grilles are designed for all types of lowpressureair conditioning, heating and ventilation systems with built in air flow and throw distance control as well as regulation of discharge angle. They can be used for both, supply air and exhaust air applications. Ventilating valves are design[r]
Overpressure dampers are used to equalize the pressure between adjacent rooms and for automatic interruption of air supply or air exhaust. Volume control dampers regulate the air flow volume in ventilation ducts and air conditioning devices. Throttling, shut off and non return dampers and flow rate[r]

This paper studies the potential to improve thermal comfort in Vietnam thanks to passive strategies. First, a thermal comfort zone for the Vietnamese is proposed by using the PMVPPD heat balance model of Fanger and the effects of adaptive mechanism of the people living in tropical hot humid region.[r]

Upfront administrative costs: Issuing the certifications requires skilled professionals and expertise; thiscan translate into an additional burden for developers and building owners because it is often attheir own cost to get a building certificate. More labour and auditing are required fo[r]
To the Building Environmental Engineer it is generally not the overall size of a building that creates the challenge it is the internal height and the lack of suitable locations for indoor climate control systems. Large span structures are synonymous with high open spaces. The Engineer seeks to cont[r]
VENTILATION The world is ventilated by natural movement of air. Inequalities of heat distribution drive the climatic air movements. The convection currents in the atmosphere are generally powerful enough to dilute the pollutants which we generate. However, pollution due to industrialisation is not a[r]
