Abstract Ventilation system affects the water evaporation rate, energy consumption and paper quality, which is considered as largest optimization potential part of multi-cylinder dryer section. Energy drying divided into three parts: steam cylinders, air heaters, power blowers exhaust fans. An model integrating condensation ventilation constructed according to control logic process flow actual ...

Radiological concerns from airborne radionuclides produced in the air region of the collimation section of the NLC Beam Delivery System were evaluated. The worker exposure during access after accelerator shutdown and the general public dose from radioactivity released to environment through ventilation system were studied. The FLUKA Monte Carlo code was used to calculate the fluence of particle...

Solar chimneys can help to reduce solar heat gain on a building envelope and enhance natural ventilation. In this work, we proposed three configurations of two combined with heated wall for the ventilation room: (I) are connected serially, (II) parallel exhaust air at separate outlets, (III) parallel, but outlets combined. The airflow rate achieved each configuration was predicted Computational...

ABSTRACTIntroduction: The emergence of COVID-19 pandemic that occurred at the end December 2019 in Wuhan, China, was a health crisis greatly affected world. Therefore, dentists and dental nurses are professionals who have very high risk being exposed to droplets aerosol particles generated during procedures. Furthermore, they also cross-infection from exposure microorganisms blood, saliva, drop...

This paper presents the successful design and implementation of several exhaust ventilation systems in a paint manufacturing factory. The ventilation systems were designed based on American Conference of Governmental Industrial Hygienists recommendations. The duct works, fans, and other parts were made and mounted by local manufacturers. The concentrations of toluene and xylene as the common so...

Abstract For efficient land use, the majority of large-scale buildings constructed in large cities are multi-story underground parking lots. The ventilation system is installed to improve indoor air quality lots, but if main fan for supply or exhaust and induction wrong place, performance will suffer. purpose this study was assess on B1F lot connected ramp, as well analyze characteristics airfl...

The indoor environment of the operating room has a significant impact on health personnel. Compared with pollutants released from occupants, amount generated by surgical equipment is greater, which easily affects patients and doctors. In this study, local exhaust ventilation (LEV) applied to an LEV mounted near operation zone remove smoke equipment. CFD technique used concentration reduction po...
