Recently, a high-volume low-speed fan (HVLS) was introduced as an alternative device to provide better air movement at a lower energy cost. This study aims to compare the distribution of airflow velocity produced by a single HVLS fan and that produced by two ceiling fans inside a room, ...
1.A high volume, low-speed fan and heating, ventilating and air condition manifold comprising:a ceiling mount;an electromagnetic motor coupled to said ceiling mount;a fan blade mount coupled to an electromagnetic motor;a plurality of fan blades wherein each of the plurality of fan blades has a...
Tunnel jet fans are designed to create a unidirectional airflow, usually from one end of the tunnel to the other. They consist of a series of powerful fans with axial blades that generate a high-velocity air jet. These fans are typically installed along t...
High performance and low noise fans--Adopting Energy-saving Multi-blade turbine fan, lower noise, Pressure spreads evenly, stable air velocity, low consumption, low running cost, service life can reach to longer than 80 thousand hours. Light, thin shape--Without filter net, thickness of ...
Fig. 12. Velocity vector pattern inside plenum chamber, test section, and flow capturing device. Fig. 13 shows the variation of velocity inside the plenum chamber, test section, and flow collector. It can be inferred from the result that the speed of the primary flow jet remains constant thr...
High speed air lake of attachment ventilation can be utilized for space heating. Warm air lake heats lower part of the occupied zone. Lower temperature at head level and higher temperature at ankle level can increase the thermal comfort [11,12]. Stratified ventilation systems, such as impinging...

positioned approximately three meters above the topof the test commodity.The data obtained from this series of work, is being used in the development ofperformance-based strategies that can be used to evaluate fire protection issues associated withlarge diameter high volume low velocity ceiling fans....
The tornado design wind speed is the expected tornado velocity with 1700- and 3000-year return periods for Risk Categories III and IV, respectively, which depend on the plan area of the building. Tornado design wind maps are provided for the estimation of the design wind speed. The directional...
