Evaporative Cooling: An Effective Cooling Technique

Before we get into details about evaporative cooling we need to understand the working of this system. This cooler is an appliance which is box-shaped with porous surfaces that let the air pass through them. The fan, which is inside the unit pulls the air from the outside into the house. Each of the porous sides is fitted with a material which can absorb water as this leads to cooling of the air.

How Evaporative Cooling Become an Effective Cooling Technique?

For effective cooling, you need to make sure that each of these pads is damp. This dampness leads to maximum cooling as dampness tends to lead to maximum evaporation. The amount of water has to be adjusted off and on making sure that the pads are damp all the time.

The Many Benefits of Evaporative Cooling:

These coolers are a preferred choice for many homeowners due to the many benefits they provide.

  • Affordable: As compared to other cooling systems, these coolers work out cost-effective. This is one factor which is considered by most homeowners as not all can afford the air-conditioning systems available these days. Not only for the appliance but even the cost of installation can fit into any budget.
  • Eco-Friendly: As we know refrigerated cooling systems tend to make the air drier, besides which certain chemicals are used for the process of cooling in these. This can be harmful not only to the atmosphere but also to the environment. Evaporative cooling is a natural process which leads to the healthy atmosphere of the air given out is much cleaner without any chemicals. You do not experience any exposure to dry air with these systems. You can keep the windows and doors open when operating these systems, which is any time healthier.
  • Easy Maintenance: These evaporative coolers are designed in a simple manner, with only two main parts, the fan motor, and the pump. The basic maintenance required for these coolers is regular flushing and draining, cleaning the screens of the pump, adding some oil and replacing the tubing if this is cracked.
  • Moisture Retained: For those living in dry climates, refrigerated cooling is a discomfort as the air tends to get drier and lead to uncalled for health problems. This is not so with evaporative cooling systems. Breathing is more comfortable with the evaporative cooling systems as compared to air-conditioners. In case of air conditioning systems, the level of moisture retention often destroys the entire functioning of the system, but this is not the system with the evaporative cooling system. If the air conditioner fins are not cleaned regularly, moisture retention can lead to health issues, which is not the case with evaporative cooling. 

Some Types of Evaporative Cooling Systems:

You have a choice between different evaporative cooling systems, some of which are

  1. Indirect Evaporative Coolers: These coolers make use of an evaporative media which is suited for a cooling tower. This helps in cooling down to the approaching temperature. These are good for small home spaces.
  2. Direct Evaporative Coolers:  This type of systems cool down the air in the surrounding before releasing it in the medium. This helps in increasing the humidity and removing stagnant air from the surroundings.
  3. Side-draft Units: These units are installed on one side of a home, like a window. This tends to blow in the cool air inside a home. This operation is similar to a window air-conditioner.

Besides the above mentioned you also have a choice between the up-draft units, combined systems, standalone systems, downdraft systems and portable evaporative systems. You need to go through the different choices available to determine which fits your requirement. Let’s go to the details and get more useful information.


Information and Benefits of Evaporative Cooling

Most homeowners have realized the importance of owning some sort of cooling systems for their homes. There are options and more options available these days and choosing the right one which fits your requirement might get a little confusing. It is thus important to get all the information on the different cooling systems before you decide on a specific one. Evaporative cooling which is direct has been used since ages.

The Working of Evaporative Coolers:

As the name suggests, evaporation is used for cooling of the air in the atmosphere. These coolers have a pump which contributes to the working of this cooler to a major extent. The pump tends to circulate the water to the cooling pads from the reservoir. The fan draws air from the outside and pushes it through the pads which are moistened.

The Apt Choice:

This evaporative cooling is an ideal choice for almost all homeowners due to the many benefits this provides. Some of these are listed below.

  1. Affordable Installation: An air-conditioner tends to be much more costly as compared to an evaporative cooler. Even if you opt for the most expensive air coolers, they will be much cheaper as compared to air-conditioners. In other words, these coolers can fit into most budgets in a comfortable manner.
  2. Friendly to the Environment: Considering the factor of the environment is important before you make a choice of any appliances for your home. As we know that the environment is facing a constant threat. These coolers do not use any chemicals for the operation and are thus considered as ‘safe’. Besides this, the air in your home is not dry as in other cooling systems. You are exposed to fresh air as the windows and the doors are open while operating this system.
  3. Maintenance is Easy: The essential parts of an evaporative cooler are the fan and the pump which can be easily replaced if damaged. The other parts are not costly or complicated in any way. Depending on how often this cooler is used, you can get it serviced twice a year to the maximum. Flushing and draining the reservoirs, replacing the tubing which is cracked, cleaning of the pump screens and lubrication is all that is required.
  4. Operation Costs: As compared to air-conditioners these coolers require only 50% of electricity. This is enough for the running of the pump and the fan.
  5. Fresh Air: As these coolers tend to increase humidity, they work ideal for those living in dry air conditions. Besides this, the pads in these coolers tend to filter the air, keeping the atmosphere healthy and clean. They also remove the ozone contaminants from the air which can lead to the build-up of molds and fungus in your room. Proper installation of evaporative cooling can keep your surroundings safe for a long time, especially if you have little children or aged patients at home.
  6. Quiet Operation: A cooling system which tends to be noisy leads to a disturbed sleep. You get up all hassled and frustrated. This is not so with the evaporative coolers.

Buying an Evaporative Cooler:

Evaporative coolers are ideal for those living in dry climates. Places where the humidity is high, these coolers take a longer time to cool the air. Check out the size of the room which requires cooling before you decide on an evaporative cooling system. There are many sizes available in the market and you need to buy the right one, which works well for the size of your room.

Deciding on the manufacturers can be easy as you have multiple listed online. Make an effort of going through the different manufacturers and comparing the prices, ensuring you are paying right and not over the top.
