          01 Fan & Air Combination
          扇机组合
          The "fan combination" plan was proposed by Ruitaifeng founder Mr. Zheng Caizhu in March 2010 and has been successfully implemented in the service market. At the same time, it was recognized by domestic industrial fan manufacturers and advocated the promotion of this design concept, and was gradually adopted Some design institutes are concerned with a cutting-edge, highly optimized design concept. "Fan-machine combination" will make the low-carbon ventilation and cooling project design more professional and create greater economic and social value for customers!
          02 Introduction to Fan Combination FAN & AIR PROFILE
          "Fan-machine combination" scheme refers to the combination of two types of products with obvious advantages, namely large-scale industrial fans (industrial ceiling fans) and evaporative coolers (commonly known as environmentally friendly air conditioners), which are popular in the Asia-Pacific region. According to the actual needs of the company, scientifically carry out combined design for the customer's large and large space environment, and maximize the comprehensive consideration of the customer's needs. After the implementation of the program, the two types of products complement each other's advantages, while exerting their effectiveness to the maximum extent. It also makes up for the shortcomings of each other's efficiency, and finally shows a very good comprehensive effect and application value.
          03 Difficulties solved by combination of fans and fans FAN & AIR PAIN POINTS
          There is no air cooler, the big fan is no problem for sensory cooling of the personnel, but the ambient temperature cannot be handled well, and there is no big fan. When only the cooler is used, a large number of air supply pipes must be installed to hang under the indoor roof. It affects the aesthetics of the space and the safety of the building, and pushes up the investment cost. Only the combination of the fan and the machine can be considered. The goals of ventilation, cooling, ventilation, saving, beauty, and safety are fully realized, which is of great significance to the improvement of indoor air in tall buildings. Significance and very good economic and practical value.
          04 Fan combination value and application range FAN & AIR VALUE & APPROPRIATE
          Fan combination value:
          1. Large air volume and ultra-quiet, forming a natural three-dimensional breeze system in tall and large indoor spaces, with wide coverage of ventilation and cooling;
          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 makes people feel 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 cannot be achieved by using large fans or evaporative chillers alone;
          4. The air cooler and fan can use one of the systems independently according to the needs of the season, or even use one or several devices in a system separately to meet the actual needs of customers to the greatest extent and reduce operating costs;
          5. Ventilation, cooling, safety, saving, beautiful appearance, all the goals that customers care about are fully realized at once;
          6. In a sense, it can replace the traditional air conditioner. If used in combination with the air conditioner, it can achieve energy saving of the air conditioner.
          Application range of fan combination:
          Especially suitable for large-scale building interior space.
          It not only pursues good ventilation and cooling, but also meets the load-bearing safety and space aesthetics of the building roof, and it also needs to save investment costs in large indoor production workplaces.

          Customer demand background
          As shown in the picture above, the customer is a large-scale well-known electrical appliance manufacturing enterprise in Guangdong. The floor plan is an assembly workshop of the enterprise. The workshop is 100m long, 70m wide, and the roof is 10m above the ground. It belongs to a brick-concrete structure + steel structure roof composite building. There are 160 workers in the workshop, mainly distributed around the six production lines. The left side of the above picture is basically unmanned. There are heating production equipment. The actual calculated environment improvement area is about 4000m ?, and the indoor temperature can reach 38 ~ in summer high temperature weather. 39 ° C, coupled with poor indoor ventilation, the customer has conceived various ways to carry out ventilation and cooling transformation for four consecutive years, including the use of traditional large-wall fans and vertical fans, but it does not have effective coverage of the ventilation effect, let alone achieve Cooling purpose; consider cooling with a large industrial fan, although the large fan has good ventilation function, it also allows employees to experience a certain temperature difference, but after all, it is not possible to cool the overall environment of the work area very well, as for the traditional central air conditioning Because of the large space of the workshop, the initial investment and operating cost budget are too large. 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 client ’s actual 4000 square meters high building interior space, two sets of systems were designed to be used in combination-a set of industrial large fan systems: the design of Ruitaifeng RTF-CF-7E "wind king" series of large fans (1.5KW, Diameter 7.3m, air volume 13200m? / Min) a total of 8 large fans; another system is Ruitai Fengrun Dongfang evaporative cooler, a total of Ruitai Fengrun Dongfang RDF23A type cooler (1.5KW, cold delivery per hour Fresh air volume 23000m?) A total of 40 units.
          The practical application effect of the Ruitaifeng "fan-machine combination" solution
          A. When both systems are turned on at the same time
          During normal production and use in high-temperature summer in summer, two systems are started at the same time-40 chillers installed on the outdoor wall continuously supply a large amount of cold air after filtering and cooling, and they are equipped with outdoor wind guide pipes into the window. Using the left and right swing air supply method, the cold fresh air up to 920,000m? Per hour is sent to the inside of the workshop, and then it is slowly rotated by 8 large fans suspended from the indoor height, with a huge air flow of 105600m? Per minute. Scope, three-dimensional drive, effective circulation and diffusion of a large amount of cold air sent by the cooler, evenly pushed to all parts of the workshop, which has a good effect of personnel and environment ventilation and cooling. While ensuring good ventilation and cooling effects, the design takes into account the safety and space aesthetics of the building roof, saves investment and daily expenses, and can produce good economic and social value. The simulation is as follows:
          B. When the two systems are opened separately
          Another highlight of the solution is: according to the actual needs of the user (when the user is not full, or the spring and autumn season is not very hot, but the workshop is a little hot), the two sets of cooling systems designed above can be used separately, even When one of the systems is used alone, it can also be controlled separately and used in a single machine, which can largely meet the actual needs of users in different seasons and different production periods, and support the promotion of good energy-saving and consumption-reduction goals for enterprises.
          06 The essence of the fan assembly
          The fan combination is essentially a highly optimized, industry-leading solution. It is actually an enhanced version of the application effect of the large fan. It can achieve a direct cooling effect on the environment that cannot be achieved by the large fan. Achieving the goal of dual cooling of personnel and the environment can meet the needs of users of higher standards.
