Evaporating cooling is a cooling technique that uses fans and moist air to lower the temperature of a space. Here’s how it works:
• Humid air is cooler than dry air. As the water evaporates from a wet surface, it absorbs heat from the surrounding air, cooling it down.
• An evaporative cooling system includes moisture-cillic pads, trays of water, or water-soaked walls that increase the humidity of the air.
• Fans then pull the moist air through the space, creating a cooling breeze. The air circulation helps the cool air reach every part of the area.
• Since the heat from the air is absorbed during the evaporation process, the overall temperature of the space lowers. The humidity goes up while the temperature goes down.
• Evaporative cooling works best in dry, hot climates where the air is not too humid to start with. It’s very efficient and cost-effective but only cools the air to around 95 degrees Fahrenheit at best.
• The key to maximum cooling is providing a large surface area for evaporation and good air circulation. Larger cillic pads or water dripping down walls provide the most surface area. Powerful fans ensure the air flow is strong enough to make the temperature difference noticeable.
• Evaporative cooling systems require little or no maintenance. The pads or filters may need occasional cleaning or replacement, but the systems themselves are designed to operate with minimal hassle.
• Evaporative cooling can be used alone or combined with other systems like air conditioning to improve efficiency. It works great as a supplement to AC or as a standalone cooling technique in suitable climates.
