High-temperature environments affect work efficiency. When people work in an environment of 28–32°C, their work efficiency begins to decline and they become more prone to fatigue. When the temperature exceeds 32°C, a person’s attention and alertness also begin to be affected. - High-temperature working environments not only affect production efficiency but also harm workers’ health, easily causing dehydration, heatstroke, and even suffocation. - Mental work is more sensitive to temperature. When the temperature reaches 29°C, the efficiency of mental work begins to decline; the higher the temperature, the shorter the duration of sustained work. - High temperatures also affect accident rates. The accident rate is low at around 20–24°C; when the temperature rises above 30°C or falls below 10°C, the accident rate increases significantly. ![](https://rundongfang.com/wp-content/uploads/products-info-001.jpg) Human comfort depends not only on temperature, but equally on factors such as air velocity, oxygen content, and humidity control. Together, these factors influence how comfortable the environment feels to the human body. Air conditioners combine all of these key performance characteristics 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 heavily, leaving workers feeling 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 is scattered, the accuracy and coordination of movements decline, limbs become weak, and the likelihood of accidents increases. - Effective temperature refers to the temperature a person perceives in a ventilated environment. 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 in a relatively hot working environment, a steady flow of fresh air at a suitable air velocity can keep workers feeling 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 | | Max 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 thoroughly stirring large volumes of indoor air to generate airflow, producing a natural breeze effect equivalent to wind force levels 1–3. It creates a soft, comfortable, natural-like breeze in high-ceiling spaces, significantly improving stuffy working environments, increasing productivity, reducing employee turnover, and achieving energy savings. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-3.jpg) ### Fan and Equipment Combination Perfectly integrates with air conditioners, evaporative air coolers, and negative-pressure exhaust fans — an innovative continuation of the ventilation and cooling system. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-1.jpg) ### Ventilation and Cooling The function of Rundongfang industrial large fans is to stir the indoor air on a large scale to create airflow, producing a level 1–3 natural breeze effect. In tall and spacious areas, they create a soft, comfortable breeze similar to natural wind, significantly improving stuffy working environments, increasing production efficiency, reducing employee turnover, and achieving energy savings. ![](https://rundongfang.com/wp-content/uploads/hvls-fans-3.jpg) ### Wide Coverage Area The rotation of the large-diameter fan blades pushes large volumes of air down to the ground, forming an airflow layer of a certain height that moves horizontally in all directions, promoting air circulation throughout the entire space. With low speed, low energy consumption, high airflow, and a wide coverage area.
