working principle :
Large ceiling fan is a series of products special developed for
energy saving,working environment improvement. As we all
know,refrigeration is not the only way to achieve the effect of
cooling and comfort. The area of a fan could blow is determined by
the diameter dimension of it, but has nothing to do with its
speed.therefore, the industrial fan with large diameter and low
speed combines all these characteristics .
After years deeply research and exploration,by integrating oversea
advanced aeronautic technology,we Dai sen developed a kind of
propeller blades with outstanding performance,it conforms
continuous and silent breeze by slowly rotation.The large volume of
airflow generated by its unique and high efficient blades push
down,thus a nearly perfect propeller exhaust is constructed.
It pushes large volume of airflow to the ground,and constructed
certain high level airflow moving horizontally,thus generates a
overall air circulation.The advantage is overall ground coverage
and three-dimensional circulation of air.
The speed of wind generated by"Large industrial ceiling fan"is
about 1-3m/s,completely calculated according to the best feeling of
cooling when the airflow pass through human skin.too strong airflow
makes people feel irritable,a sense of being blown directly,too
high speed of airflow also makes people dizzy,only the through the
evaporation of skin combines of breeze speed,can beautifies
people's feeling of cooling.

Comparison of three refrigeration methods in 1000 square meter
plant
| Refrigeration mode | Quantity | Power/unit | Tall power | General comparison |
| Central air conditioner | 1 | 80KW | 80KW | The walls and doors and windows of the plant are required to be insulated. The cost of one-time investment of the equipment is high, and the maintenance cost of replacing the filter element and adding refrigerant is high |
| Traditional industrial fan | 40 | 0.3KW | 12KW | The installation of traditional wall fans is limited by walls and columns. The power lines of floor fans are scattered, which has potential safety hazards. It is not safe for the hair of staff members to be mixed into the fan blades, which occupies a small space and covers a short service life |
| 7.3M large industrial ceiling fan | 1 | 1.5KW | 1.5KW | Large coverage area, long service life, low maintenance cost, installation does not occupy the workshop space, safety and environmental protection |
The energy consumption of large industrial ceiling fan is about 1 /
50 of that of central air conditioner and 1 / 10 of that of
traditional industrial wall fan
***Suitable places of installation: Any high enough structure of
factory,sport center,logistic place,car repair workshops,supermarket, airport,package
workshop,animal breading industry,any kinds of hall,as well as
