The principle of water cooling is to use hot air to pass through a fully humidified water curtain and evaporate, and then blow out cold air without water mist to achieve the cooling effect. The higher the ambient temperature, the lower the relative humidity, and the more obvious the cooling effect. That is to say, the higher the temperature and the drier the environment, the better the cooling effect. It is completely different from air-conditioning compression cooling and spraying.
