How does Dawang's large safety fan affect the airflow?

The airflow and super large air volume of the Dawang large safety fan is one of the effective ways to keep employees and guests comfortable in your space.The airflow formed by the fan blades of Dawang safety fan pushes towards the ground.Outside the Dawangfan diameter,the airflow transforms into horizontal air movement.According to ASHRAE 55 thermal comfort calculation,Dawang large safety fan can provide comfortable airflow over a large area.In addition,Dawang large industrial safety fan has a variable speed control function,allowing users to adjust the airflow to provide the best cooling effect required.

Fresh air is usually not evenly distributed throughout the space.For example,one of the most common air distribution configurations for HVAC systems is a supply with overhead return air.In common heating applications,this configuration will cause significant stratification with indoor air after being heated and supplied, thereby preventing fresh air from circulating to the height of the occupants.According to the ASHRAE 62.1 standard,it is required to increase the ventilation rate by 20% in order to provide necessary fresh air for the occupants in the room.However,in a space where a large fan is installed,the air layers can be well integrated,eliminating stratification,and supplying fresh air to the level required by the occupants.

In a naturally ventilated space,fresh air is passively distributed throughout the space,so stagnant zones may appear in local areas,resulting in poor air quality and accumulation of pollutants.Dawang's large safety fan disperses these stagnant zones and increases the circulation of fresh air,evenly distributing it in the entire space,fully improving indoor air quality.

How much will the Dawang large safety fan increase the air flow to improve the ventilation effect of the space?

The CFD analysis of Dawang large safety fans on industrial spaces shows that Dawang large safety fans provide measurable benefits.For example,a 24 ft (7.3M) Dawang large safety fan directly pushes the airflow in an area of about 1500 square meters.Along the horizontal direction, the Dawang large safety fan can push the airflow to a larger area (depending on the installation height,Ground obstacles,fan models, etc).If you need to customize a professional ventilation plan to improve the airflow of your space, please consult the sales hotline of Dawang Large Safety Fan 00 869 189 2150 0189.

Should Dawang large industrial fans be used during public health events such as flu season?

There are many variables in every facility and application.Without in-depth research on the data of each case,it is impossible to determine whether increasing the air flow rate will have a significant impact on health. Dawang large industrial safety fans put the safety and health of customers first.In addition to complying with the design standards and concepts specified by ASHRAE,they also follow the guidelines outlined in the CDC and WHO.

Dawang large safety fan can dilute and reduce the concentration of airborne pathogens,increase the ventilation rate,and provide a higher dilution capacity,thereby reducing the risk of potential infection.

Dawang large safety fan recommends the following:

In a naturally ventilated space,increase the intake of ventilation (outdoor air) as much as possible and develop good respiratory hygiene habits.Cover your cough or sneeze with your elbow or tissue and wash your hands regularly.Clean and disinfect frequently touched objects and surfaces,such as workstations,keyboards,phones,armrests and door handles.
