Air conditioning fan is a household appliance that combines electric fan and air conditioning mode, with multiple functions such as air supply, cooling, and humidification. Using water as a medium, it can deliver cold air below room temperature or warm and humid air. Most air conditioning fans have dust removal nets that can filter the air. If there is another layer of photocatalyst on the dust removal net, it can also have a sterilizing effect. When the air conditioning fan starts cooling, it only has 60-80W, which is the same as a refrigerator, so it won't consume a lot of electricity.
