High-temperature environments affect work efficiency. When people work in an environment of 28–32°C, their work efficiency begins to decline and they fatigue more easily. When the temperature rises above 32°C, people’s attention and alertness also begin to be affected. - Hot working environments not only reduce productivity but also harm workers’ health, easily causing dehydration, heatstroke, and even suffocation. - Mental work is even more sensitive to temperature. When the temperature reaches 29°C, the efficiency of mental work begins to drop—the higher the temperature, the shorter the duration of sustained work. - High temperatures also affect accident rates. Accidents occur least frequently at around 20–24°C, but when the temperature rises above 30°C or falls below 10°C, the accident rate increases substantially. ![](https://rundongfang.com/wp-content/uploads/products-info-001.jpg) Human comfort depends not only on temperature but also on other equally important factors such as air velocity, oxygen content, and humidity control. Together, these factors determine how comfortable the environment feels to the human body. Air conditioners combine all of these key performance features to ensure a high-quality, comfortable indoor air environment. ## The Relationship Between Physical Work Efficiency, Temperature, and Air Velocity - If the temperature is too high, body temperature rises and the body sweats profusely, leaving workers exhausted all over; in severe cases, this can lead to serious dehydration, heatstroke, and fainting. - At the same time, the central nervous system is suppressed, attention becomes scattered, the accuracy and coordination of movements decline, limbs weaken, and the likelihood of accidents increases. - Effective temperature refers to the temperature the human body perceives in an environment with airflow. When the wet-bulb temperature remains constant, the higher the air velocity, the lower the effective temperature. Therefore, air velocity affects both human comfort and work efficiency. - Even when the working environment is relatively hot, maintaining a steady flow of fresh air at a certain velocity can keep workers comfortable and mitigate the various adverse effects caused by high temperatures. | Model | RDF-S3600 | RDF-S4200 | RDF-S4200 | RDF-B6200 | RDF-B6200 | RDF-B6700 | RDF-B6700 | RDF-H7200 | RDF-H7200 | | -------- | --------- | --------- | --------- | --------- | --------- | --------- | --------- | --------- | --------- | | Diameter | 3600mm | 4200mm | 5200mm | 6200mm | 6200mm | 6700mm | 6700mm | 7200mm | 7200mm | | | (12ft) | (14ft) | (17ft) | (20ft) | (20ft) | (22ft) | (22ft) | (24ft) | (24ft) | | Input Voltage/Frequency | Single-phase 220V/50HZ | Single-phase 220V/50HZ | Single-phase 220V/50HZ | Single-phase 220V/50HZ | Single-phase 380V/50HZ | Single-phase 220V/50HZ | Single-phase 380V/50HZ | Single-phase 220V/50HZ | Single-phase 380V/50HZ | | Rated Current | 2.6A | 2.6A | 2.6A | 4.5A | 3.1A | 4.5A | 3.1A | 4.5A | 3.1A | | Power (kw) | 0.66kw | 0.66kw | 0.66kw | 1.3kw | 1.3kw | 1.3kw | 1.3kw | 1.3kw | 1.3kw | | Maximum Speed | 90RPM | 80RPM | 70RPM | 60RPM | 60RPM | 55RPM | 55RPM | 58RPM | 58RPM | | Max Airflow | 4552m³/min | 5306m³/min | 7065m³/min | 10747m³/min | 10747m³/min | 12560m³/min | 12560m³/min | 15197m³/min | 15197m³/min | | Noise Level | ﹤38d/B | ﹤38d/B | ﹤39d/B | ﹤39d/B | ﹤39d/B | ﹤39d/B | ﹤39d/B | ﹤39d/B | ﹤39d/B | | Weight | 72KG | 75KG | 78KG | 100KG | 100KG | 105KG | 105KG | 115KG | 115KG | | Coverage | ∅20-24m | ∅22-26m | ∅25-30m | ∅32-37m | ∅32-37m | ∅35-40m | ∅35-40m | ∅38-44m | ∅38-44m | ![](https://rundongfang.com/wp-content/uploads/hvls-fans-4.jpg) ### Three-Dimensional Natural Breeze The Rundongfang industrial large fan works by stirring large volumes of indoor air to create airflow, producing a natural breeze effect equivalent to force levels 1–3. In tall and spacious buildings, it creates a soft, comfortable breeze similar to natural wind, significantly improving hot and stuffy working environments, boosting productivity, reducing employee turnover, and achieving energy savings. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-3.jpg) ### Fan and Equipment Combination for Complementary Cooling Perfectly combines with air conditioners, evaporative air coolers, and negative pressure exhaust fans—an innovative continuation of ventilation and cooling systems. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-1.jpg) ### Ventilation and Cooling The RunDongFang industrial large fan works by stirring large volumes of indoor air to create wind speeds that produce a level 1-3 natural breeze effect, creating a soft, comfortable natural-wind-like effect in tall, spacious areas. It significantly improves hot and stuffy working environments, increases productivity, reduces employee turnover, and achieves energy savings. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-3.jpg) ### Wide Coverage Area The rotation of large-diameter fan blades pushes massive amounts of air down to the ground, forming an airflow layer of a certain height that moves horizontally in all directions along the floor, promoting air circulation throughout the entire space. It features low rotational speed, low energy consumption, high air volume, and a wide coverage area.
