The wet curtain cooler is a simple device that uses the latent heat of evaporation of water to cool down. It mainly consists of the following parts:
1. Fan: Provides air volume.
2. Water tank: stores circulating water.
3. Wet curtain cylinder: Install a wet curtain. When the air passes through the wet curtain cylinder, the wet curtain absorbs water, evaporates, absorbs heat and cools down.
4. Wet curtain: made of fiber material, with large water absorption area.
5. Water pump: Pump the water from the water tank to the top to pour the wet curtain.
6. Damper: adjust the air volume.
The working principle is that the fan provides airflow, which evaporates through the moist wet curtain, absorbs heat and cools down, and then blows out cold air.
The advantage is that it has a simple structure, is easy to use, can quickly achieve local cooling, and is suitable for temporary use. The disadvantage is that the cooling effect is limited and the cold air temperature is not low enough. It is used in temporary construction sites, open spaces and other places where local temporary cooling is required.
The wet curtain air cooler is a device that cools the air. It mainly consists of a fan, a water tank, and a wet curtain cylinder. The working principle is:
1. The fan inhales air and passes through the wet curtain in the water tank.
2. The wet curtain sheet absorbs water, evaporates and cools down the air.
3. Negative pressure is generated after passing through the wet curtain cylinder, sending cold air into the use place.
4. The water in the water tank is circulated and poured upward through the water pump to supplement the moisture evaporated from the wet curtain.
5. The air supply volume and cooling volume can be controlled by adjusting the damper and water pump.
