The EPA states typically indoor air quality is five times worse than outdoor air quality. New technologies have been developed for indoor air exchangers (sometimes called heat recovery ventilators or energy recovery ventilators), which can give you all the benefits of having open windows, but without losing all of the energy.
We’ve all heard about the problems of air pollution in the environment, but most people are shocked to find out that the air quality in their own homes is actually a much greater problem. There are a number of reasons why the air quality in your home is so much worse than outside air:
1. VOC (volatile organic chemicals) being released from carpets and furniture.
2. fumes from household cleaners and paints.
3. mold from damp bathrooms and basements.
4. naturally occurring radon gas which seeps up through the foundation floors.
5. fumes from cooking and smoking.
6. pet dander.
To improve the quality of air in your home, you can open your windows. But of course, in the wintertime you will not want to do this. the summer months, you will not want to open your windows if your running your air conditioner.
This is where an indoor air exchanger can be so helpful. By bringing in fresh outdoor air while capturing up to 80% of the potential heat loss, these units can significantly improve your indoor air quality in an energy efficient manner. And models which are energy recovery ventilators can actually transfer the humidity between the air streams, keeping the humidity in your house when you need it in the winter, and keeping humidity out in the summertime when you don’t want it.
You can see examples of various models of indoor air exchangers online on Amazon.com: indoor air exchangers. Consider purchasing an air purifier, it is less expensive.
Some models of air exchangers can be mounted in a window or wall opening, much like a room air conditioner is installed.
HOW THEY WORK
the way an indoor air exchanger works is that the air ducts for the intake air are intertwined with the air duct for the outflow air in the mixing chamber. As a result, the air flows do not mix, but the heat (or cooling in the summer) from the two air flows are exchanged. As a result, fresh air from the outside can come in without losing all of the heat (or cooling) from the inside air, thereby saving up to 80% of the energy.
The key elements of a typical air exchanger include:
Air Ports: From one port, fresh air is drawn from the outside, and from the other port, indoor air is ducted and expelled out.
The exchanger is a chamber where the separate air channels mix while separated from each other by highly conductive metal, which allows efficient heat transfer between the two air streams.
A material made of foam, metal, etc. Which removes dust and dirt particles from the outside air intake.
A flat blade inside the air exchanger, which controls the amount of airflow.
Channels in your house where the air flows through.
A reservoir here water condensation is collected.
If the air exchanger is located in a basement below grade, then it will need a pump to eject the water condensate.
Indoor air exchangers are a great innovation for improving the quality of air in your home for you and your family, on an energy efficient basis. However, you will want to carefully choose which model is appropriate for your particular home situation, and if you already have one, you will want to do the proper routine maintenance for it.
The air purifier is an easier less expensive way to go. If you plan on staying in your home over five years spending the money for a exchanger is a good idea, if your a first time buyer and plan to buy up in the near future then save your money and get a portable room purifier. Good for your health and you budget. Happy Breathing!
