All About Dehumidifiers Green. Building. Advisor. An energy efficient home in a hot, humid climate should have a tight envelope, thick insulation, energy efficient appliances, and low solar gain windows. If you include these features in a new home, your air conditioner wont run as often as your neighbors. Thats good. But there is a downside to the fact that your air conditioner runs rarely during the hours that your house has no active cooling, it also has no active dehumidification. As a result, your indoor relative humidity is going to rise. Daikin Scroll Compressor Pdf' title='Daikin Scroll Compressor Pdf' />This problem is fairly well understood. In hot, humid climates, a run of the mill house has better control of indoor humidity levels than an energy efficient house. If you live in an energy efficient house in a humid location like the Southeastern U. S., you may need a dehumidifier. Why do some homes need supplemental dehumidification To figure out whether you need a dehumidifier, its worth considering the factors that raise indoor relative humidity levels. Some of these factors apply to all climates indoor humidity levels rise when there are many people or pets living in the house when residents take many showers when there are lots of houseplants when residents cook frequently and when someone mops the floor.

Do you want to say which brand I know Daikin were looking into this. What are the main differences in R32 vs R410 From a consumer perspective I dont think many. Other factors some of which are counterintuitive apply particularly to houses in hot, humid climates The tighter the house and the better the windows, the more likely it is that youll need supplemental dehumidification. During the summer, the more you ventilate, the more likely it is that youll need supplemental dehumidification.

According to researcher Armin Rudd, Moving ducts from the attic to the conditioned space. Insulated, air sealed part of a building that is actively heated andor cooled for occupant comfort. The reason once you move ducts indoors, your air conditioner wont run as often. A study of homes in Houston. One of the landmark studies looking at humidity problems in energy efficient homes was a 2. Building America study in Houston, Texas conducted by three researchers from the Building Science Corporation Armin Rudd, Joseph Lstiburek, and Kohta Ueno. The researchers monitored humidity levels in Building America homes with excellent thermal envelopes high levels of insulation, low levels of air leakage, and above average windows and compared the homes with a control group consisting of ordinary new homes.

In other words, the energy efficient homes were more humid and less comfortable than the run of the mill homes. The researchers monitored different types of dehumidification equipment installed to address these issues, and discovered that the least expensive solution was the most effective. The researchers reported, The stand alone dehumidifier in an interior hall closet system, with central fan integrated supply ventilation and fan cycling, had the lowest initial cost and operating cost while providing good humidity control. This system is recommended. The stand alone dehumidifier system involved installation of an off the shelf 5. The dehumidistat built into the dehumidifier energized the dehumidifier whenever the humidity level rose above the user setting. The fan cycling control for the supply ventilation system was set to 3. The solution is fairly simple. A stand alone dehumidifier costs between 2. Cnc Program Simulator. There are two basic types units that are hooked up to a drain, and units that come with a plastic tub that needs to be emptied once or twice a day. Needless to say, most people prefer the convenience of a unit that is hooked up to a drain. The capacity of a residential dehumidifier is reported in pints per day. Typical residential dehumidifiers have capacities ranging from 2. If you choose to buy a unit with a plastic tub that is emptied by hand, you should be aware that most dehumidifiers have tub volumes that are less than half the rated capacity of the unit. That means that if you expect the dehumidifier to achieve its rated capacity, you would need to empty the tub two or three times each day. Most stand alone dehumidifiers have controls that allow the user to choose a relative humidity RH setpoint and a fan speed. Of course, if you choose a low RH and a high fan speed, the appliance will use more energy than if you choose a higher RH and lower fan speed. The efficiency of a dehumidifier its energy factor or EF is reported in liters per k. Wh. The federal government sets minimum efficiency standards for dehumidifiers 1. Wh for units rated at 3. Wh for units rated at 3. Wh for units rated at 4. Wh for units rated at 5. The minimum requirement for an Energy Star labeled dehumidifier is more stringent, of course Any Energy Star. Labeling system sponsored by the Environmental Protection Agency and the US Department of Energy for labeling the most energy efficient products on the market applies to a wide range of products, from computers and office equipment to refrigerators and air conditioners. EF of 1. 8. 5 litersk. Wh. For Energy Star dehumidifiers with a capacity of more than 7. EF rises to 2. 8 litersk. Wh. Dry air is good, but wringing moisture from the air is energy intensive. Keeping your indoor humidity low is generally a good idea. During the winter, lowering the indoor humidity is easy and relatively cheap all you have to do is operate a ventilation fan. If you bring in cold outdoor air, the outdoor air will be dry. Custom Name Badge Templates more. Cold air cant hold much moisture. The longer you run a ventilation fan, the lower your indoor relative humidity. To achieve this benefit, either an exhaust fan for example, a bath exhaust fan or a supply fan or both will work. Operating your ventilation fan at a high rate during the winter carries an energy penalty, of course, because all of that outdoor air has to be heated. But the energy penalty associated with winter ventilation is much less than the energy penalty associated with running a dehumidifier. And fortunately, its rare to have high indoor humidity during the winter. Generally, the problem only occurs if the house is small and occupied by a large family, or if the house has a wet basement. Most homes have the opposite problem indoor air is too dry, not too humid, during the winter. During the summer, ventilation wont help you lower the indoor relative humidity especially if you live in the humid Southeast. When the weather is hot, the outdoor air is usually very humid. The more you ventilate, the more humidity you bring into your house. So during the summer, the best approach is to keep ventilation to a minimum. As long as the outdoor temperature is hot, your air conditioner will probably be running for a few hours every day enough to keep the indoor humidity under control. But during the spring and fall, your air conditioner wont be running. Thats when you may need to turn on your dehumidifier. Many homeowners aim for 5. If you use a dehumidifier to reach this goal, your dehumidifier will add heat to the house. But thats not a big problem if the indoor temperature gets too hot, your central air conditioner will turn on, further lowering your indoor humidity level. Dehumidifying your indoor air under these circumstances is a good thing to do. Dryer indoor air is better for you house and probably better for your health.
