The chilled ceiling (CC) displacement ventilation (DV) system is one of the air conditioning systems that have shown effectiveness in providing air quality through supplying 100% fresh air. The CC/DV system effectiveness and economic viability has been increased when return fraction was recirculated...
“This year marks the 50thanniversary of the Clean Air Act, which has been responsible for dramatic improvements in air quality. However, Florida residents are breathing more unhealthy air compared to last year’s report, driven by extreme heat as a result of climate change...

Mixed air temperature calculator — HVAC The mixed air temperature formula can be changed to determine the supply air temperature of a HVAC (heating, ventilation, and air conditioning) system. HVAC refers to a system that is responsible for maintaining comfortable and healthy indoor air quality. Th...
Energy savings of up to 20.6% can be realized using mixed supply air while maintaining IAQ compared with energy used for the 100% fresh air. 展开 关键词: Contaminant transport in plumes Indoor air quality with mixed return air Chilled ceiling displacement ventilation ...
Evaluating visual encoding quality of a mixed reality user interface for human–machine co-assembly in complex operational terrainAuthors: Z Wang, X Zhang, L Li, Y Zhou, Z Lu, Y Dai… Year: 2023 Cites: 1 Abstract:… Through human–machine interaction techniques and mixed reality (MR) ...
Contemporary concerns for improving environmental performance in buildings have led to an increased interest in natural ventilation (NV) either on its own or in combination with air-conditioning (mixed mode (MM)) as an alternative to traditional heating, ventilation and cooling (HVAC) systems. HVAC...
During the aerobic stability test, pH increased by 1.39, 1.67, 1.69 and 0.74 for the Control, M, L and EM silages, but only 0.40 and 0.34 for E and EL silages, respectively. Upon exposure to air, the LA concentration in the L silage was evidently (P < 0.05) decreased, whereas LA...
