A new utility shaft at the US Department of Energy's Waste Isolation Pilot Plant (WIPP) in New Mexico has now reached nearly 90% of the way to the underground waste repository depth of 2150 feet (655 ...
The ISHVAC conference series was initiated by Tsinghua University in 1991. It is the premier international HVAC conference initiated in China and has played a significant role in the development of HV...
Methane emissions in longwall coal mines can arise from a variety of geologic and production factors, where ventilation and degasification are primary control measures to prevent excessive methane lev...
A mine’s ventilation system is an important component of an underground mining system. It provides a sufficient quantity of air to maintain suitable working environment. Therefore, the status of mine ...
This paper proposes numerical investigations carried out on a small scale tunnel model airing to study the fire-induced smoke control by longitudinal and longitudinal-natural ventilation systems. We s...
Volatile organic compounds (VOC) outgassing from newly manufactured baked and unbaked ventilation filters were examined using gas chromatography/mass spectrometry following thermodesorption (TD-GC/MS...
With the aim of evaluating capabilities of a ventilation system to control the spread of smoke in the emergency operating mode, thereby providing conditions for safe evacuation of people from a fire-s...
In the quest for energy conservative building design, there is now a great opportunity for a flexible and sophisticated air conditioning system capable of addressing better thermal comfort, indoor air...
An experimental study of the thermal performance of an air-flow window with triple glazing is described. The measurements were carried out in a climatic chamber under conditions close to a winter seas...
As a recent tendency to take high interest in the environmental problem, the time has come to reconsider the present working environment. Especially, air pollution caused by the generated metallic fum...
Air pollution caused by the generated metallic fume during the progress of welding in a fabrication shop is one of unavoidable issues for labor health. Especially, a worker is likely to be exposed to ...
Large diameter and low rotational speed propellers have been applied for a number of merchant vessels to improve the propeller efficiency, while the propeller immersion has become small relatively.
The present paper proposes the analysis of the efficiency of water to air heat exchanger with heat pipes for the mechanical ventilation system. The performed study is based on the necessity of the ...
Some aspects concerning the heat reducing for ventilation, achieved by using heat recovering components and a combined heating--ventilating system, assuring both comfort and human health are presented...
Ventilation control efficiency of air pollutant emitted from a type P5000 metal etcher (Applied Materials, Inc.) during preventive maintenance was investigated in this study. Sulfur hexafluoride (SF...
