The cooling effect of HVLS (High Volume Low Speed) industrial fans is mainly reflected in the following aspects:
1. Natural Breeze Effect: The HVLS fan generates a large area of natural breeze through slowly rotating large blades, which can cover vast spaces and provide continuous cooling for the human body and object surfaces.
2. Sweat evaporation acceleration: The airflow of the HVLS fan can accelerate the evaporation of human sweat, because the process of sweat evaporation requires air flow to carry away heat. When sweat evaporates, it absorbs heat from the surface of the skin, producing a cooling effect and effectively reducing the perceived temperature.
3. Air circulation improvement: The HVLS fan improves the air circulation in the space by driving a large amount of air flow, eliminating temperature stratification, allowing cold air to be evenly distributed, and reducing local overheating areas.
4. Humidity reduction: Good air circulation helps to reduce the humidity in the space. The decrease in humidity itself can improve the cooling effect, because humid air makes people feel hotter.
5. Energy saving cooling: Compared with traditional air conditioning systems, HVLS fans have much lower energy consumption in cooling. They can provide effective cooling effects without increasing too much energy consumption.
6. Used in conjunction with other systems: HVLS fans can be used in conjunction with air conditioning systems to improve air flow and efficiency, thereby achieving better cooling effects.
7. Reduce heat stress: In applications such as animal husbandry, HVLS fans can effectively reduce heat stress in livestock, improve their production efficiency and welfare.
The airflow generated by HVLS fans can make the human body feel comfortable, sweat quickly evaporates, and the body feel effectively cools by 5-8 ° C. The airflow formed by this type of fan forms a conical shape from top to bottom and is pushed towards the ground. As more airflow is pushed towards the ground, it flows horizontally and encounters horizontal airflow from side barriers or adjacent fans before being pushed upwards to the roof. This enhances air circulation in all directions, multiple angles, and without dead angles, eliminating temperature stratification. Circulating air also has a positive effect on reducing humidity, which traditional industrial floor fans or blowers cannot achieve. On the contrary, HVLS fans can generate a large amount of upward airflow, forcing hot air to blow down from the ceiling, keeping employees warm during winter.
