If the supermarket around your home is extremely hot in summer and extremely cold in winter, you often have chest tightness and shortness of breath. On the same road, a new supermarket has opened, with good ventilation, cool in summer and warm in winter. Which supermarket will you choose to go to in the future? If you are the owner of a supermarket, the cost of installing air conditioners is high, and the installation of cooling fans and laying too many pipes will affect the appearance, what method will you choose? Here we will introduce a large ceiling fan -- HVLS (High-Volume, Low-Speed) fan. Take the newly opened Costo in China as an example.
Around mid-December last year, the Costo Suzhou store opened. As the world's second-largest retailer and the world's first membership-based warehouse and wholesale club, almost all Suzhou residents poured in when Costo officially opened. There are so many people in the supermarket that it is comparable to the Spring Festival travel scene. There are huge crowds inside and long queues outside. There is a messenger in this supermarket with a dazzling array of commodities who silently protects the shopping crowd and the shopping environment - the industrial energy-saving large HVLS ceiling fan.
Costco Suzhou Store covers an area of 50 acres and has a construction area of about 52,000 square meters. Among them, the first-floor store area is approximately 16,000 square meters. The interior is equipped with daily refrigerated products, fresh aquatic products, refrigerated fruits and vegetables, meat, poultry, eggs and milk, and cooked food; there are more than 20 sub-districts for baking, beverages, snack foods, etc. With such a large business area, it is normal for supermarkets to be overloaded with traffic. Now that the global epidemic is raging, air pollution is severe, and stockpiling and preparing for the New Year have become a habit. Considering how to improve customers' comfort, air quality, and health when purchasing in the case of many customers in the supermarket, large HVLS ceiling fans were installed in the supermarket.
The supermarket is full of people, the internal environment is closed, the carbon dioxide concentration in the personnel activity area is high, and customers will experience chest tightness and shortness of breath. After installing the energy-saving large HVLS ceiling fan, by promoting airflow, the fresh air in the upper part of the supermarket with low carbon dioxide concentration is pushed to the upper part of the supermarket. The bottom of the supermarket has dramatically improved the air quality inside the supermarket, thereby improving customers' comfort. The maximum diameter of industrial ceiling fans can reach 7.3m/24ft. The rotation speed is 0-54 revolutions per minute. The air volume generated is as high as 13800 cubic meters per minute. When running, the blades are upturned, just like a helicopter's propeller, to make the airflow within 30 meters from the center of the fan during operation. The coverage area is increased to more than 1000-1500 square meters, forming a conical airflow to circulate downward, eliminating The air inside the supermarket can be pushed down to every corner of the ground, promoting air circulation and improving the air quality of the supermarket, so that customers can shop with peace of mind.
In the case of supermarket heating in cold winter, industrial energy-saving large HVLS ceiling fans can still be used, which can effectively eliminate air stratification and achieve the effect of uniform temperature. Energy-efficient large fans mix hot roof air with cool ground air, a process called de-stratification. Large ceiling fans gather the airflow and push it down, creating a cone of airflow until it reaches the ground, helping the environment get to the floor. The temperature on the roof tends to be the same, and the thermostat is set at 22°C in winter. Still, the temperature in the staff activity area at the bottom of the supermarket is 12°C to 13°C, and the temperature in the ceiling area reaches 28°C. Customers and staff feel cold, and the shopping environment is quite uncomfortable. , the accumulation of hot air leads to a severe waste of energy. After the installation of large industrial ceiling fans, the temperature control of the ground and roof is controlled within 1-3°C, the ground temperature can reach at least 20°C, the power of the energy-saving large HVLS ceiling fan is only 1.5KW, and the heating cost in winter can be saved by about 35%. Improve customer comfort and achieve the effect of energy saving and emission reduction.
Above all, installing an HVLS ceiling fan would be an energy-saving and beautiful way for supermarkets to provide customers with a comfortable shopping experience.
