1. Refrigeration Principle:
The system utilizes an advanced "direct evaporative cooling" technology, which works on the principle that water absorbs heat during evaporation. This process occurs at a constant enthalpy, meaning that the sensible heat from the air is absorbed, leading to a decrease in the dry bulb temperature of the air. This natural phenomenon is commonly experienced in daily life—for example, when you step out of the ocean and a breeze blows over your wet skin, you feel a sudden coolness. This is due to the evaporation of water, which takes heat away from the air, effectively lowering its temperature.
2. Wet Curtain Features:
As fresh air passes through the core component of the system—a multi-layer corrugated fiber laminate known as the wet curtain—the water on the surface evaporates directly into the air stream. This process cools the air to nearly its wet bulb temperature. The wet curtain offers excellent water absorption and airflow performance, along with a built-in filtration function. Its design ensures that the contact area between water and air is approximately 100 times the surface area, maximizing efficiency. The material is strong, waterproof, resistant to corrosion, and maintains its shape over time. With proper maintenance, it can last more than six years, making it a durable and cost-effective solution for long-term use.
3. Ventilation Principle:
In hot summer conditions, the difference between the dry and wet bulb temperatures of the air is significant, resulting in a more effective cooling effect. Outdoor air is first filtered by the evaporative air conditioner, then cooled through the evaporation process before being continuously circulated into the room. At the same time, stale air—rich in odors, dust, and heat—is expelled outside. This not only lowers the indoor temperature but also increases oxygen levels, improving overall air quality. As a result, the evaporative air conditioner provides both cooling and ventilation, creating a comfortable and healthy environment for living and working.
