Advantages Of Evaporative Cooling System

Whenever a sunny, warm day comes to mind, you see yourself drenched in sweat.  after that, when you come home, you get absolutely energized because of your cooling system. There are many cooling systems in the market, but evaporative cooling systems are the most efficient of all.

The process of liquid water evaporating from a surface and lowering its temperature is known as evaporative cooling.

Process Of Cooling Using Evaporation:

Having the knowledge of heat and evaporation systems is necessary to understand evaporative cooling. Latent heat is the term used to describe the heat stored in the water. Water cools things down by absorbing heat from nearby surfaces. 

This happens when the temperature rises enough to cause water to evaporate. And because of the temperature, the gas releases and removes the additional heat. There is a decrease in heat transfer and thus a reduction in surface temperature this is how the evaporative cooling functions.

Tips on Selecting and Installing Evaporative Cooling for Home or Office

When it comes to choosing evaporative cooling systems there’re two choices that people opt for, air conditioners or evaporative coolers. In fact, some people opt for evaporative coolers above air conditioners for the fact that they work better under certain circumstances. It meets all the needs of air conditioning at a far less price than air conditioners. Modern evaporative coolers cost less comparatively; they are energy efficient and are very effective when it comes to cooling.

How does it work?

The humid and dry climate is where these evaporative coolers work best. Once a highly efficient evaporative cooling unit is connected to the ductwork of home or office, the unit pulls in hot air from outside. This hot air is then passed through water-saturated pads, which cools down the hot air using water evaporation process and then it is distributed through the ductwork. The cool air is then released into the room pushing the hot air out of the room through open windows and doors, keeping the room cool. While normal air conditioners re-circulate the same air, evaporative coolers help to provide fresh air at home constantly while operating.

Benefits of choosing Evaporative Cooling systems

  • It uses the fresh outdoor air and the filtering process takes care of the dust pollution
  • It helps eliminate the smoke and odor emitted while cooking
  • It can be installed on the ground, in the attic or even mounted on the wall making it user-friendly and flexible.
  • Cooling system of evaporative coolers does not harm the ozone layer while functioning
  • The evaporative cooling system offers low-cost installation and saves up to 75% more energy than your regular air conditioner.
  • Makes less noise while functioning.

Installation and selection

The cubic feet per minute air it filters in the house, measure the ratings of the evaporative coolers. Models may range from 3000 to 25000 CFM and the capacity can be verified with the help of the manufacturers based on the climate and requirements of the client. The coolers can either down flow evaporative coolers or portable horizontal cooler unit based on the requirements of the individual. Small portable evaporative coolers on wheels are also available these days but they generally provide the slight cooling effect.

Following are some tips on selecting the correct evaporative cooler to install in home or office:

  • Not every room in your home or office requires the same kind of evaporative cooling. Hence choose your air conditioner based on the cooling requirement, keeping the area of installation in mind.
  • There are two major types of coolers such as centralized coolers and ducted coolers. The ducted coolers are best suited for larger homes and office spaces, which call for cooling multiple bigger rooms and halls. Whereas if you require cooling smaller spaces, you can use the ductless central coolers.
  • Evaporative coolers come in portable small sizes as well. Choose this type of cooler if you want a hassle free uncomplicated installation as these can be placed easily at any desired place in a room. But these can cool small rooms only as portability reduces cooling capacity. These are best for moderate climates and not at all suitable for harsh summers.
  • Horizontal evaporative cooling systems are better choices compared to down flow coolers as they do not leak easily. These coolers can be easily mounted on floors and hence are easier to use and install.

With these sensible tips, you can enjoy the many benefits of evaporative cooling and ensure that you can maximize cooling benefits for your home or office.

Easy Installation Tips For Evaporative Cooler

You must have heard about “evaporative cooling”. Evaporative cooling is actually a very simple, cost effective and natural way to cool your home. The use of latest technology has eventually helped us to create an intelligent and user and environment friendly cooling systems which ultimately minimizes the electricity cost also. Basically these coolers work on the phenomena in which fan inside the cooling unit pulls the air from outside. The water is stored in a pan at the bottom of the cooler and each side is fixed with pads of water absorbing material. A pump lifts the water to the top of each side thus cooling the house effectively. The performance of these coolers is best when the level of outside humidity is low.

How to Install Evaporative cooler?

There are basically two ways to install evaporative coolers:

  • First is to install the cooler in the centralized location.
  • Second is to connect the cooler to the ducts distributing air to different rooms.

The former installation works best in case of small houses and the later one is best for a big house with many rooms.

Instruction steps:

  • Support assembly Installation: This is the first and the basic step while installing your cooling system. Usually the manufacturer gives support assembly along with the evaporative cooler. Fix the support assembly at the appropriate place. Project the window towards outside in order to get the unit properly placed.
  • Positioning of cooler on Assembly: After the installation of support assembly, next step is to set the cooler. Rest the cooler on the support assembly supporting the unit to the maximum extent. Make sure to attach the brackets and wall hangers to the unit.
  • Run the water line: Now is the time to connect the water line to the cooler. Also ensure that the cut off valve is installed between the cooler and the water. Cut off valve is vital as it helps in draining the water out of the unit thus saving the whole system from getting damaged.
  • Air Vent Installation: Next step is to attach the air vent cover that comes with the kit. It brings the cool air into your home thus making your home cool and comfortable.

More Tips to keep in mind:

  • Use Low voltage thermostats instead of high voltage thermostats because high voltage thermostats allow large temperature swings which is not good for the cooler.
  • Check the float valve setting after one pump cycle.
  • Rooftop installations should have water cut off facility in order to avoid leakage and wastage of water.
  • To maintain personal safety, electrical disconnect should be available near the cooler. This becomes all the more important in case of roof top installations. These days cooler units come with an in-built electrical disconnect.
  • Don’t forget to use a barometric damper at the fan discharge of the evaporative cooler. These dampers make it much easier to switch between heating/air condition and evaporative cooling.
  • Minimum 3 ft. of area on the sides of the cooler should be kept clear for easy maintenance. It helps in repairing electrical parts in a hassle free manner.
  • Make sure that the cooler inlet is 10 ft away from gas flues, kitchen, kid’s room and bathroom.
  • If you have both the evaporative cooler and the central air unit, then never operate them at the same time. In that case, neither will work properly. In fact, they will work against each other. It is of no use to keep two systems in the house but neither works efficiently. Systems producing loud noise, water leakage without cooling your home are not actually energy efficient. They just add on to your electricity bill.

Awesome! Your new evaporative air cooler is finally installed. Just make sure that there are no leaks around the cooler and the window.
