Description

Technical Field

[0001] The invention relates to the technical field of air conditioning devices, and in particular to an air-purifying air-conditioning fan. Background Art

[0002] The water evaporative air conditioning device (abbreviated as air conditioning fan) is a living environment appliance that regulates the temperature and humidity of the air. Its principle is that a water evaporation carrier is installed at the air inlet of the fan assembly. The fan drives the air through the water evaporation carrier, causing the water to vaporize at room temperature. The water evaporates and absorbs the heat of vaporization to cool the air. The unvaporized water flows back to the water tank for recycling. The cooled air is blown out through the air duct and the air outlet, giving people a cool feeling directly. Since the air conditioning fan does not use a compressor but only an ordinary fan, it has low energy consumption and low equipment cost. It is deeply loved by consumers in the hot summer and has become the preferred appliance for modern families. Traditional air conditioning fans have a single function and can only be used in hot summers, but cannot be used all year round, and have a single season of use. Summary of the invention
