01 Fan & Air Combination
The "fan machine combination" solution was proposed by Mr. Zheng Caizheng, the founder of Ruitaifeng, in March 2010, and has been successfully implemented in the service market. At the same time, it was recognized by domestic large fan manufacturers and advocated to promote the design concept. Some design institutes pay attention to a cutting-edge, highly optimized design concept. The "fan-machine combination" is bound to make the low-carbon ventilation and cooling engineering design more professional and create greater economic and social value for customers.
02 Fan Machine Portfolio Introduction FAN & AIR PROFILE
The "fan-machine combination" solution refers to the products that have obvious advantages in the large-scale industrial fans (industrial ceiling fans) and evaporative coolers (commonly known as environmentally-friendly air conditioners) that are popular in the Asia-Pacific region. After professional calculations, they are combined with customer work sites. To meet the actual needs of customers, scientifically carry out combined design for customers 'large and large space environments, and take into account omnidirectional meticulous considerations for customers' needs to the greatest extent, so that after the implementation of the plan, the advantages of the two types of products complement each other, and at the same time, their respective effects are maximized, It also makes up for the lack of each other's efficiency, and finally reflects a very good comprehensive effect and application value.
03 FAN & AIR PAIN POINTS
There is no air cooler, and the large fan does not have any problem in sensory cooling of personnel, but it does not handle the ambient temperature well. Without the large fan, when only the air cooler is used, a large number of air supply pipes must be installed to hang below the indoor roof. Affects the aesthetics of the space and the safety of the building, which drives up the investment cost. Only the fan-machine combination can be taken into account. The goals of ventilation, cooling, ventilation, saving, aesthetics, and safety have been fully achieved. It has a significant impact on the improvement of indoor air in tall buildings. Significance and very good economic and practical value.
04 Fan machine combination value and application range FAN & AIR VALUE & APPROPRIATE
Fan machine combination value:
1. Large air volume and ultra-quiet, forming a natural three-dimensional breeze system in a large and large indoor space, with wide ventilation and cooling coverage;
2. Not only can the staff realize the sensory cooling of the human body, but also the overall cooling of the environment. With a certain wind speed, it is comfortable. For places that require environmental humidity, the indoor air can be kept dry to avoid corrosion and deterioration of equipment and products;
3. Create a fresh air environment, which can achieve all-round environmental improvement goals that can not be achieved by using large fans alone or evaporative coolers alone;
4. According to the needs of the season, the cooler and fan can use one of the systems separately, or even use one or several devices in a system, to meet the actual needs of customers to the greatest extent and reduce operating costs;
5. Ventilation, cooling, safety, economy, and beauty, all customer goals are realized at once;
6. In a sense, it can replace the traditional air conditioner. If it is used in combination with the air conditioner, it can save energy.
Fan machine combination application range:
It is especially suitable for interior spaces of large buildings.
Large indoor production workplaces that not only pursue good ventilation and cooling, but also meet the load-bearing safety, space aesthetics of the building roof, and save investment costs.

Customer demand background
As shown in the figure above, the customer is a large and well-known electrical appliance manufacturing company in Guangdong. The floor plan is an assembly workshop of the company. The workshop is 100m long, 70m wide, and the roof is 10m above the ground. It belongs to a brick-concrete + steel roof composite building. There are 160 workers in the workshop, which are mainly distributed around 6 production lines. The left side of the picture above is basically unmanned and has heating production equipment. The actual calculation environment is about 4000m? The indoor temperature can reach 38 ~ At 39 ° C, and the indoor ventilation is not smooth, the customer has envisaged various ways to carry out ventilation and cooling transformation for 4 consecutive years, including the use of traditional large wall fans and vertical fans, but it does not have a ventilation effect of effective coverage, let alone achieve The purpose of cooling; I have considered using large industrial fans to cool down, but although the large fans have good ventilation functions, they can also allow employees to experience a certain temperature difference, but after all, they cannot cool the overall environment of the work area. As for traditional central air conditioning Due to the large volume of the workshop space, the initial investment and operating cost budget were too large to stop. The customer finally selected the "fan machine combination" solution submitted by the company's design department. The solution is summarized as follows:
Ruitaifeng "fan machine combination" solution
Based on the actual needs of the customer's actual 4,000 square meters of large building interior space, two sets of systems were designed for use—a set of industrial large fan systems: the Ruitai Feng RTF-CF-7E “Wind King” series of large fans (1.5KW, Diameter 7.3m, air volume 13200m? / Min), a total of 8 large fans; the other system is Ruitai Fengrun Dongfang evaporative air cooler, a total of Ruitai Fengrun Dongfang RDF23A type air cooler (1.5KW, cooling per hour) Fresh air volume 23000m?) 40 units in total.
Real application effect of Ruitaifeng's "fan-machine combination" solution
A. When two systems are turned on at the same time
During normal production and use in hot weather in summer, two sets of systems are turned on and running at the same time-40 cold air fans installed on the wall are continuously sending a large amount of cold and fresh air after filtering and cooling, and the outdoor air ducts are only installed when entering the window. The left-right swing air supply method can deliver up to 920,000 m? Of cold fresh air to the interior of the workshop, supplemented by 8 large fans suspended at high altitudes in the room to rotate slowly, with a large air flow of 105,600 m? Per minute, Scope and three-dimensional driving, effectively circulate and diffuse a large amount of fresh air sent by the cooler, and evenly push it around the workshop, which has a good ventilation and cooling effect for both personnel and the environment. While ensuring good ventilation and cooling effects, the design takes into account the safety of the roof of the building and the aesthetics of the space, saving investment and daily expenses, and generating good economic and social value. The simulation is as follows:
B. When the two systems are turned on separately
Another highlight of this solution is: according to the actual needs of the user (when the user is not full, or when the spring and autumn are not very hot, but the workshop is a bit sultry), the two sets of cooling systems designed above can be used independently, even in the When one of these systems is used alone, it can also achieve independent control and stand-alone use, which can largely meet the actual needs of users in different seasons and different production periods, and support the promotion of good energy conservation and consumption reduction goals for enterprises.
06 The essence of the fan assembly
The fan-machine combination is essentially a highly optimized and industry-leading solution. It is actually an enhanced version of the large fan application effect. It can achieve the direct cooling effect of the environment that cannot be achieved by the large fan. To achieve the goal of dual cooling of personnel and environment, can meet the needs of higher standards of users.
