Cooling principle and function of environmentally friendly air conditioning (air cooler)Environmental air conditioning cooling principle and function
principle
The general environmental requirement is a ventilation volume of 25-30 times per hour;
Public places with high pedestrian traffic require a ventilation rate of 30-40 times per hour;
Places or production workshops with dense crowds and high temperatures require 40-50 air changes per hour;
High temperature and severely polluted production workshops require a ventilation volume of 50-60 times per hour;
In humid southern regions, the frequency of air exchange should be appropriately increased, while in hotter northern regions, the frequency of air exchange can be appropriately reduced.
The core cooling component of Ruitai Wind evaporative air cooler is the high-efficiency evaporative wet curtain, which is a "multi-layer corrugated fiber composite". According to the natural physical phenomenon of evaporation heat absorption - "water evaporation absorbs heat, and the evaporation area affects the evaporation efficiency", air is supplied indoors through a fan. The outdoor air flows through a wet curtain soaked in water, and the air fully contacts with moisture while absorbing sensible heat in the air, thereby achieving the purpose of cooling, ventilation, dust removal, and increasing fresh air. It is particularly suitable for high temperature and crowded places.Direct cooling and conveying fresh air fan combination product
Reference for ventilation frequency in various occasions
The definition of air exchange rate: Air exchange rate (times/hour)=total indoor air supply volume (m ³/h) ÷ [indoor area (㎡) × indoor height (m)];The general environmental requirement is a ventilation volume of 25-30 times per hour;
Public places with high pedestrian traffic require a ventilation rate of 30-40 times per hour;
Places or production workshops with dense crowds and high temperatures require 40-50 air changes per hour;
High temperature and severely polluted production workshops require a ventilation volume of 50-60 times per hour;
In humid southern regions, the frequency of air exchange should be appropriately increased, while in hotter northern regions, the frequency of air exchange can be appropriately reduced.
Why use Ruitai Wind evaporative air cooler?
Strong cooling effect: In southern regions, the cooling effect can generally reach 4 ℃~10 ℃, while in hot and dry areas, the cooling effect can reach 4 ℃~15 ℃, and the cooling effect is rapid
High air volume, far air supply: The maximum air volume per hour is 20000 to 85000 cubic meters, which can be selected according to customer needs. High air pressure, far air supply
Single unit consumes less electricity, about 1 kWh per hour: Installing central air conditioning and evaporative air coolers in the same area consumes only about 1/8 of the power of central air conditioning
Good air quality: integrates ventilation, air exchange, dust isolation, and cooling, increases oxygen content in the space, improves work efficiency, and allows for flexible selection of overall air supply or post air supply
Low investment, high efficiency: Compared with evaporative air coolers, evaporative air coolers account for about 1/5 of the total investment in central air conditioning when installed under the same conditions and area

Introduction to fan combination
The "fan combination" scheme refers to the combination design of Fengxing International's large industrial fans (super large ceiling fans) and evaporative air coolers (commonly known as environmentally friendly air conditioners), which each have obvious advantages. After professional calculation and combined with the actual needs of the customer's work site, the combination design is scientifically carried out for the customer's large space environment, and meticulous consideration is given to the customer's needs to the maximum extent. After the implementation of the scheme, the advantages of the two types of products complement each other, and while maximizing their respective effects, they also make up for each other's shortcomings in efficiency, ultimately reflecting a very good comprehensive effect and application value together. Over the years, the concept of "fan combination" has gradually become popular and has been continuously praised, imitated, and applied by domestic and foreign peers.
The "Fan Combination" solution was proposed by Mr. Zheng Caichong, founder of Guangdong Ruitai Company (Ruitai Wind), in March 2010 and has been successfully implemented in the service market. It significantly optimizes the ventilation and cooling effect for users, saves a lot of costs, and creates a cutting-edge and highly optimized engineering design concept for users. This major innovative concept has now developed to version 4.0 of "Fan Combination", which is bound to lead the application of low-carbon ventilation and cooling engineering design towards a more specialized direction and create greater economic and social value for users!
Difficulties in solving fan combination problems
Without air coolers, it is not a problem for Da Bi to provide sensory cooling for personnel, but it cannot handle the environmental temperature very well. Without large fans, it is necessary to set up a large number of air supply ducts to hang below the indoor roof when using only air coolers, which affects the aesthetics of the space and the safety of the building, and increases investment costs. Only by combining fans can the goals of ventilation, cooling, air exchange, conservation, aesthetics, and safety be fully achieved. This has significant significance and very good economic and practical value for improving indoor air in large buildings.
The value of fan combination
1. The high wind volume creates a natural three-dimensional breeze system in large indoor spaces, with extensive ventilation and cooling coverage;
2. Not only can it help staff achieve sensory cooling of the human body, but it can also achieve overall environmental cooling, coupled with a certain wind speed, making the human body feel comfortable. For places with humidity requirements, indoor air can be kept dry to prevent equipment and products from rusting or deteriorating;
3. Creating a fresh air environment can achieve environmental improvement goals that cannot be achieved by using large fans or evaporative air coolers alone;
4. The air cooler and fan can be used separately according to seasonal needs, and even one or several devices in a single system can be used separately to maximize customer satisfaction and reduce operating costs;
5. Ventilation, cooling, safety, conservation, and aesthetics, all customer concerns are fully achieved at once;
6. In a sense, traditional air conditioning can be used in combination with air conditioning to achieve energy efficiency.
Practical Application Case of Ruitai Wind's "Fan Combination" Solution (Example)
A、 When two systems are activated
During normal production and use in hot summer weather, two systems are activated simultaneously. Taking the example of 40 outdoor wall mounted air coolers continuously delivering filtered and cooled fresh air, the system uses a left-right swing air supply method to deliver up to 920000m ³ of fresh air per hour to the interior of the workshop after entering the window through an outdoor air duct. In addition, 8 large fans suspended at high indoor locations are slowly rotated to achieve a maximum air circulation of 105600m ³ per minute for large-scale, three-dimensional driving. The large amount of fresh air sent in by the air coolers is effectively circulated and dispersed, evenly pushed to various parts of the workshop, and has a dual good ventilation and cooling effect on personnel and environment. This design not only ensures good ventilation and cooling effects, but also takes into account the safety of building roof load-bearing and spatial aesthetics, saving investment and daily operating costs, and generating good economic and social value.
B、 When two systems are opened separately
Another highlight of this solution is that the two cooling systems designed above can be used separately according to the actual needs of users (when the user is not fully occupied during production, or when the spring and autumn seasons are not very hot, but the workshop is somewhat stuffy). Even when using one of the systems separately, it can be controlled separately and used as a standalone unit, which can meet the actual needs of users in different seasons and production periods, and support the promotion of good energy conservation and consumption reduction goals for enterprises.

Principle and function of large fan coolingCooling Principle & Function o f Large Industrial Fan
principleThe concept of natural ventilation and coolness is combined with modern aviation wing technology, which drives the flow of air through the slow rotation of huge fan blades, generating continuous and three-dimensional circulating wind.
The large area of gentle breeze flow accelerates the evaporation rate of sweat on the human body surface, producing a natural cooling effect, just like feeling the cool feeling of sea breeze after swimming out to sea, making the surface of the human skin feel a temperature difference of about 5-7 ℃. In addition, the large energy-saving fan feature of Ruitai Wind adjusts the wind speed to maintain body moisture while regulating human sensation, thereby enhancing the comfort of human sensation.
