Evaporative Cool: What Is It And Why Is It So Good?

Have you heard of evaporative cool? It is a natural and healthy way to cool your home without the need for artificial refrigerants. This article will explain the basics.

Evaporative cooling uses evaporated water to cool the air. This is what happens when you leave a swimming pool after a hot day. Your wet body will feel chilled until it dries. This is due to the evaporating of water.

Evaporative cooling uses the natural heat sink effect of evaporation. The heat absorbed by the air can be used to produce latent heat that is necessary to evaporate water. The amount of water that can evaporate will determine how much sensible heat is absorbed.

Evaporative cooling can either be indirect, passive, or mixed. Direct evaporative cooling increases the water content of the cooled atmosphere because it comes in direct contact with evaporated water. Indirect evaporative cooling is where the heat exchanger cools the air while evaporation takes place. The water content of the cooled vapor remains the same. Direct evaporative cooling is only recommended for areas with very low relative humidity.

Passive evaporation is when evaporation occurs naturally. Passive evaporation can cool a space where there is still water or flowing water. A hybrid evaporative method is one where evaporation must be controlled using some mechanical device.

How Modern Evaporative Cooling Works

The cooling pad is the heart of modern evaporative cooling systems. It is where water evaporates, and then air passes through. The evaporative cooling pads are made from fluted cellulose sheets, which are then glued together. To prevent rot, the material is coated with special compounds that ensure long service life and minimal maintenance.

The cooling pads are covered with water. A water distribution system distributes water evenly over the cooling pads. This ensures that the entire surface is hydrated to maximize cooling. The pads are drawn in the air by fans which creates negative pressure. Contact between water and air causes evaporation. The fan circulates cool air around the area via a control system.

Evaporative Cooling Has Many Benefits

  • Cleaner air reduces the chance of infection by bacteria and viruses
  • There are no refrigerants or chemicals
  • Low energy consumption
  • Equipment virtually maintenance-free
  • Evaporative cooling and bacteria/virus

All of our evaporative cooling systems come with pre-filtering to ensure clean air. This, combined with the slightly humidified air from evaporative cooling reduces the spread of bacteria and viruses.

Evaporative Cooling, Humidity

At a given temperature and pressure, a volume of air can absorb and retain a certain amount of water vapor. It is considered to be at 65% relative humidity if it contains more than 65% of its moisture potential.

Evaporation is more effective when the temperature is higher than normal. The cooling effect works best when it is most needed.

Evaporative coolers can also be used in high-humidity areas. However, they are more efficient than fans that circulate warm air. The temperature and humidity of the environment that you wish to cool will determine how much humidity our coolers will add. In ventilated areas, where the unit exhausts its air, the slight increase in humidity is barely noticeable.
