Ceiling-Fan-Integrated Air Conditioning (CFIAC): Age-of-air, Air Pollution, and Airflow Distribution
Ceiling-Fan-Integrated-Air Conditioning (CFIAC) is a heating ventilation and air conditioning (HVAC) design approach that jets supply into the vicinity of ceiling fans to be mixed distributed within room. This eliminates terminal ductwork diffusers provides very efficient cooling for occupants. Two previously published papers have described velocity, temperature, thermal comfort fields in space...
The majority of cultural heritage is stored in archives, libraries and museum storage spaces. To reduce degradation risks, many archives adopt the use archival boxes, among other means, to provide necessary climate control comply with strict legislation requirements regarding temperature relative air humidity. A ambient indoor assumed adequate environmental conditions near objects. Guidelines f...
the natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. the wind power injects outdoor fresh air into the building. a good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. a serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...
Implementation of diffuse ceiling ventilation (DCV) is slowly gaining momentum and applications in building have taken off with countries like Denmark, Finland Netherlands taking the lead Europe. However, DCV yet to gain a foothold Sweden so not many installations are known, their performance relation Swedish practice established. A school southern was subsequently renovated two classrooms were...
An airflow window has great potential for conserving energy and improving indoor air quality in residential buildings. Existing airflow windows use a single airflow path, and their energy performance can be studied using several computational models. A dual-airflow window with triple glazing can conserve more energy than a singleairflow window, because the former works like a cross-counterflow ...
BACKGROUND Over the past few decades, evidence has emerged suggesting that nasal airflow asymmetry and brain asymmetry are linked. The nose exhibits asymmetrical airflow, with the dominant airflow alternating from one nasal passage to the other over a period of hours. Some authors have suggested a correlation between cerebral hemisphere dominance and nostril dominance. Others have proposed an a...
An appropriate estimate of a building airflow network, which consists of infiltration and interzonal airflow, is important when determining indoor air quality, energy use, and for detecting contaminants. The objective of this study was to estimate the airflow network of a commercial building using CO2 as a tracer. CO2 is naturally present in the environment and is generated inside buildings by ...
Familial aggregation of chronic obstructive pulmonary disease (COPD) has been demonstrated, but linkage analysis of COPD-related phenotypes has not been reported previously. An autosomal 10 cM genome-wide scan of short tandem repeat (STR) polymorphic markers was analyzed for linkage to COPD-related phenotypes in 585 members of 72 pedigrees ascertained through severe, early-onset COPD probands w...
