The Real Deal On Portable Air Conditioners

Many people nowadays have cooling systems inside their homes to help combat against the scorching heat that summers may bring. The market is now filled with numerous brands and types of air conditioners that are affordable ranging from the window type, split type and the portable ones that are slowly gaining popularity in homes as well.

A portable unit may seem big and bulky at first glance since it is around 30 inches tall and weighs about 80 lbs. The great thing about it though is that it is a self-contained component that does not require any installation because it can stand by itself on the floor without the need for your wall or window to contain it. Most are also equipped with wheels for easy mobility.

One of the advantages that a portable air conditioner offers is that you don?t need to create a hole on your wall or block a window to accommodate the unit. You can easily transfer it from one room to another eliminating the need to install numerous window type air conditioners in several rooms. It can also help you save on electric bills if you will just be using it in a room instead of switching on the entire centralized system.

It just has a downside of costing more than your regular window type air conditioner. Also, although it has a similar cooling capacity as that with split type systems it can sometimes be noisy compared to the split type kind whose compressor is located outside. If noise really matters for you, look for portable air conditioners that make lesser amount of noise.

You may be wondering if a portable air conditioner is capable enough to cool big and large rooms. Actually, it all depends upon the model. You need to take a look at the cooling capacity of each unit and check the room size that it could productively cool.

Since air conditioners consume a lot of electricity, it would be wise to choose a unit that is energy efficient and has a lower electrical usage. Today the standard and acceptable energy efficiency ratio should be at least 10.

It may come as a shock to you but portable air conditioners are reasonably priced. Their prices have dropped considerably through the years and are not costly anymore. Of course, you can expect units with a higher cooling capacity to cost more. If you want a cooling system but don?t plan on investing in a centralized cooling setup, purchasing a portable air conditioner may be a good option.

HVAC Noise: Solving a Common Noise Problem

Noise pollution caused by rooftop and ground-level HVAC equipment including chillers, boilers, and air handlers has become one of the most annoying as well as dangerous environmental problems in cities worldwide. As urban noise increases and residential growth multiplies, residents and communities are demanding better noise reduction solutions for heating, ventilation and air conditioning equipment. Outdoor community noise problems caused by commercial and industrial HVAC systems may require an acoustically engineered Sound Barrier Wall.

Sound barrier walls have been used extensively for years in the transportation and industrial fields. A sound barrier wall is an exterior structure, normally made of masonry or earth, designed to protect sensitive land uses, such as residential areas from noise pollution. These noise pollution abatement products are now being used to help eliminate unwanted noise from HVAC systems as well.

Traditional material for noise barrier walls for HVAC systems has been reflective products. Reflective products, like concrete or brick, simply redirect the unwanted sound waves in other directions, and can actually increase noise by unintentionally reflecting sound waves. There is a better solution. Absorptive sound enclosures and architectural screens actually absorb the unwanted sound waves, minimizing the risk of unintentional reflected noise. Absorptive sound walls reduce reflections and are able to maintain the effectiveness of the barrier. Therefore, the overall noise level is reduced. The advanced materials found in absorptive barrier walls present a much more effective noise barrier solution. There are different solutions for this problem such as the LSE System, an absorptive sound barrier created by Sound Fighter Systems, that actually absorbs the sound waves that hit it, thereby eliminating unwanted noise.

So, if you are facing problems with noisy HVAC equipment an absorptive sound barrier wall is obviously the most effective noise mitigation solution available for this very demanding application. Absorptive walls outperform and outlast all other noise reduction products. Plus, many systems such as the LSE System are an aesthetically pleasing HVAC sound wall with the added benefit of noise pollution reduction.

Murray Stacy is Vice President of Sound Fighter Systems, LLC, which has been researching, designing and manufacturing highly efficient absorptive noise barrier walls since 1973, making it the oldest established manufacturer of such products in America. Sound Fighter walls have been produced for unique noise mitigation applications around the world, and several of the company's walls are in their 30th year of effective service. http://www.soundfighter.com
