Cooling wet pads are primarily used for cooling and humidifying poultry houses. They mainly adopt the “cooling pad-negative pressure fan” model, with the working principle roughly as follows: The cooling process of the cooling pad is completed within its core component—the cooling wet pad. When the fan draws hot outdoor air through the cooling wet pad covered with cooling water, the cooling water transitions from liquid to gaseous water molecules, thereby absorbing a significant amount of thermal energy from the air and causing a rapid drop in air temperature. After mixing with the indoor hot air, it is then expelled outdoors through the negative pressure fan.
