Commercial square space is tall and spacious, only the use of air conditioning is expensive and not environmentally friendly. Combined with the Sharip fan, it can drive the flow of cold air in the shopping mall, and the low speed and large air volume can make the staff in the shopping mall feel the most comfortable temperature and wind speed. At the same time, this combination can increase the set temperature of the air conditioner by 1~2 ° C, and even stop the air conditioner directly according to the season and weather, and only turn on the big fan, which realizes energy saving and consumption reduction and reduces the operating costs of the mall.
