The science behind the cool breeze you feel when you are beside the ocean or a river has finally been decrypted. The cooler air is felt gently on the skin because over the period of time as hot air blows across the surface of the sea or river, it prompts some of the water to evaporate and assimilate the heat wave. The warm air is then cooled simply because of the evaporation process and its widely called sea breeze.
Wondering how this relate to an air conditioning system? Well, Braemar evaporative air conditioner cooling process works similarly to the evaporative process of the sea. You see, when hot air enters the cooling unit that was carefully mounted on your roof, where it will be cool as it makes it way through the intelligently designed moistened Chillcel® pads. At the end of this process, a fan was then designed to blow this magnificently cooled air throughout your home.
Hot air in the house is forced out through open windows and doors providing your entire home with a complete change of air at least every two minutes.
The evaporative cooling process is the nature’s way of cooling without inhaling any artificially made up air conditioning.
Evaporative Cooling Advancement
If you live at a place which has dry and hot weather conditions, evaporative cooling are considered as one of the very effective means of cooling the premises and give the feeling of comfort, at least within the confines of your dwelling or work place. They are also known as swamp coolers and use the natural phenomenon of evaporation of water to cool the air temperature inside. Any air draft that passes through water is cooler and that is what we experience commonly in nature at the river bank or sea shore. Adopting same principles, the air outside the building which is hot is pulled inside the building through wet pads of these machines. The water soaked in the special pads cools the air which is made to pass through it before entering into the room. The temperature inside the room gradually comes down due to the supply of this cool air which is moisture laden as well.
Built on basic engineering design principles and commonly available materials, the cost of the evaporative cooling is very affordable but its effectiveness in providing the cool interior environment, even when the mercury is soaring, is remarkable. It barely requires any changes in the existing set up of the place and can be ordinarily installed without difficulty. All you need is water supply arrangement and electric connection available near the unit and it is ready to serve.
The pre-condition of using evaporative cooling system is the weather condition of your place in the summer months. It has to be dry hot climate since its efficiency is best in these conditions. In case your place has high humidity, then it is of scant use for the region. It can be installed on the roof tops, windows or even in places where hot air from outside can be pushed in. One has to consider the best options available for the place. The aesthetic design of the unit looks decent on appearance.
There are many discernible advantages for opting for evaporative cooling system but the foremost and most prominent reasons for their use are:
• Low upfront cost
• Low Running cost as it consumes less electricity
Evaporative cooling is Cost Effective:
Compared to compressor air conditioners, the evaporative cooling unit comes at fraction of their cost and thus is affordable to large section of people. People with limited budget can also plan to install these systems at their residence or work place. There are different types, models and capacities of evaporative cooling available in the market to choose from and one can always take advice about the most suitable variant for the individual’s needs.
Less Recurring Cost:
In the times when energy costs are escalating, evaporative cooling are the welcome alternatives to save on energy cost. There is one small motor required to run an evaporative cooling but compressor air conditioner requires two or more heavy duty motors to function; thus the electric consumption is high. The studies show that compared to refrigerated air conditioners, the running cost of evaporative cooling is only about 15% to 25%!!! It saves you huge amounts annually.
The list of advantages of the evaporative cooling systems does not end here. Since the evaporative cooling system operation requires outdoor air to be pushed inside, most people consider it good for health.
Evaporative cooling provide fresh air circulation:
While using evaporative cooling, one can keep the windows and doors of the room open to facilitate the circulation of fresh air which is good for health. In contrast, the refrigerated air conditioning system works effectively only when the windows and doors are closed since it sucks the air in the room and send it back after lowering its temperature. One can enjoy a good sleep in the night in its quiet humid cooling and save yourself from the feeling of dryness of skin, eyes or nose.
Ideal for outdoor work shops
There are many work places which are in the open areas or require free ventilation. In these places, the refrigerated air conditioners cannot be used as they require closed or confined areas. The evaporative cooling are the only logical solution to provide cooling environment there. This obviously enhances the comfort of the people working there and improving their efficiencies as well as for the benefit of clients/visitors to the business.
Evaporative cooling is good for wooden Furniture:
The moisture laden air pushed by evaporative cooling also helps to enhance the durability of the wooden furniture in the household or work since it provides natural humid atmosphere which prevents the wood to dry out.
Since most of the evaporative cooling system is periodically replaceable parts like wet pads, nozzles, blades, etc are low cost items, the maintenance cost to keep the unit working for long years is also not high.
Despite its above-mentioned advantages, there are some inherent limitations which should be borne in mind before purchasing this system.
The major drawback for evaporative cooling is its reduced effectiveness in regions or places where the ambient air humidity is high. Unlike compressed air conditioners which can be used in all weather conditions, they can be used only in hot and dry climates.
Since the operation of this system requires regular water supply, it is not suitable for places where water is scarce or cannot be made accessible to the unit. If the water is hard, then the likelihood of salt and mineral deposits makes it prone to frequent cleaning and maintenance.
