Principle The principle of temperature drop: Water will absorb the heat from the hot air when steaming naturally. Its working principle: Extract wind through air blower, and the blower produces press, the air crosses the wet curtain, at the same time the water pump delivers water to the cloth water pipe on the wet curtain, and moisten the face of the whole wet curtain evenly, and the special angle of the wet curtain makes the water flow into one side where the air enters the wind directly, absorb a large amount of heat to lower the temperature through wet curtain, and filter it, which can make the wind nice, cool, moist and fresh. The water without evaporation falls back to the chassis forming waterway circulation. There are water level inductors on the chassis, when the water level lands to the fixed water level, it automatically open inlet valve to supply the source of water till the height of the booking water level, then close the inlet valve automatically.
