Get the Perfect Cooling With Evaporative Cooling Systems

On November 11, 2015 by Melissa Hamler

Evaporative cooling is one of the best ways of cooling the house and to maintain an optimum temperature. But there is a much simpler concept behind this mechanism. Evaporative cooling is the process by which a liquid is made to evaporate. This has a cooling effect on the surrounding areas. The idea is very well implemented and used for industrial and domestic purposes. This is the reason why evaporative cooling has become a household name in areas which have warmer climatic conditions.

Understanding Evaporative Cooling

The whole mechanism of cooling the house with this process is a natural occurrence. Let us clearly understand the science behind it. Water is made to evaporate and turn into a liquid or the vapor state. In the liquid state, water has a lot of heat collected. When it goes into the gaseous phase, the latent heat is lost to the environment. The loss of heat ensures cooling properties of the system. Evaporative cooling systems work along the same principles to cool the buildings.

Let us now go through a few terms that we will need in relation to evaporative cooling:

  • Cooling tower: A cooling tower is basically a device that converts the warm air into the vapor state. That doesn’t end there. The water vapor is then released into the atmosphere. With this step comes in the whole concept of cooling. This heat rejection system works well to cool the buildings.
  • HVAC system: HVAC stands for the three processes of heating, ventilation and air conditioning. In this situation, the natural heat of the sun is used for evaporation of the liquid particles. This also takes help of refrigerants and heat exchangers in the process.
  • Dry bulb temperature: This is more commonly referred to as air temperature. A thermometer placed outdoors measures the temperature of the atmosphere.
  • Wet bulb temperature: This is another important term here. It is defined as the lowest temperature that the evaporation of water can lead to.

Advantages of using evaporative cooling:

Evaporative cooling is a method which has a number of benefits to offer. Let us see some of them.

  • The initial purchase costs less as compared to other cooling methods.
  • The compatibility of evaporative cooling with solar energy makes it a very energy efficient system. Overall, the energy usage is significantly reduced.
  • Evaporative cooling is environment friendly. This process involves no greenhouse gas production or even CFC’s or HFC’s. That means, this process does not contribute to the ozone depletion.
  • People who are affected by allergies will find this evaporated air safe and clean.
  • The air produced here is wet. So for places with low humidity, this extra moisture in the air will come in handy.

Why is evaporative cooling better than traditional air conditioning?

Even though the conventional air conditioners have the same purpose of cooling as the evaporative cooling systems, there are a few basic differences.

  • Evaporative cooling introduces fresh air in the house and removes the allergens.
  • Air conditioners take the humidity out of the air. The evaporative cooling system produces wet air.
  • Even if the door to the room or house is kept open, there will be no problems with the cooling apparatus. In case of the air conditioners, the doors will have to be closed at all the times.
  • Evaporative cooling systems come with lower energy usage, lower operating costs and in general cost a lot less than air conditioners.

Considering all these factors, evaporative cooling systems are beneficial for cooling the house or office with moist air. If you need more details then let’s have a look here and get more info about evaporative cooling.
