dehumidifier or air conditioner in damp, unfinished basement??
Comments (7)Get a dehumidifier. Here's the problem with what was said: Air that can hold more moisture is a good, not a bad, thing because you are talking about relative humidity -- the amount of moisture in the air relative to what it can hold at its temperature: So, by doing nothing other than warming air, you can lower its relative humidity. If you were to put a heater in your basement and warm it from, say, 65 degrees to 75 degrees, you would drop the relative humidity of the basement because, even though the air has the same absolute quantity of moisture in it, the 75 degree air could hold more than the 65 degree air, so the relative humidity is less. But a dehumidifier is even better than a heater because it removes moisture in two ways -- it drops the air to a temperature below its dewpoint, removing actual moisture, and then warms the air, lower the relative humidity further. An air conditioner is a problem for at least two reasons. First, because it cools as it dehumidifies, its ability to dehumidify is limited to situations where cooling is needed. If it's below 70 degrees or so outside, the a/c evaporator is liable to freeze, and at that point it'll keep running but do nothing as far as cooling or dehumidifying until it's shut off and the evaporator is allowed to thaw out. Second, because the a/c lowers the temperature of the air, it makes condensation on those walls and other surfaces more, not less, likely. Why? Because if the surface of a wall is, say 64 degrees, and the air is 65 degrees at a high humidity level, it doesn't take much heat transfer for the wall to pull the air near it down just one degree (and if the humidity approaches 100 percent, that might be enough to create condensation). On the other hand, if the air is 75 degrees with the same absolute quantity of moisture it had at 65 degrees, the wall has to drop the air 11 degrees to create the same condensation. Obviously that's much less likely. And that's the benefit you'd get from a heater alone. With the dehumidifier, the air won't have the same absolute quantity of moisture at 75 as it had at 65 -- it'll have less. Finally, the walls won't stay 64 degrees once you warm the room up. They'll gradually warm up too, further reducing the risk of condensation....See MoreCan a portable air conditioner truly save energy vs. central type
Comments (13)Portable air conditioners will prevent cash and lower your energy bills, however provided that you're strategic in however use it. Okay, currently that we tend to got the cliff-notes answer out of method, let's dive a touch deeper into however you'll use a conveyable air-con unit to avoid wasting cash on your monthly energy bills. that does not mean that you simply cannot use this kind of air conditioning to assist you economize and lower your energy bills. If a conveyable air conditioning is such an energy hog, then however can it save money? If you propose on moving a conveyable air conditioning from space to space, these area unit powerfully suggested. what proportion cash does one assume you've got lost, by cooling rooms that do not really want to be cooled? Instead, attempt setting your thermostat at an inexpensive, nonetheless still comparatively snug, temperature, so use a conveyable air conditioning to quickly quiet down the foremost vital rooms. It's true that they're not the foremost energy economical air conditioning accessible, however if you're clever in however you utilize the device, there's little question that it will prevent quite little bit of cash and lower your energy bills....See Moremy portable air conditioner, dirt like browish stuff, help!
Comments (17)Hello, sorry I'm back again I just buy a new filter yesterday and use it today, I don't think it the filter. Because after the new filter, the brownish soft stuff still in there. I look inside my units, and the brownish stuff is on the metal (left side) of the evaporator coil. I don't think it mold since it seem like it a well cut length piece of something they glue on the metal. Foam? Mold? but I don't think mold would grow so well cut shape on the metal. Around the coil, I also see white foam place inside the units. Those white foam are fine. But something on the metal looks like foam too, but it turns to brownish color and smushy, sticky stuff. Thank you This been bothering me, I really wonder what can it be. I'm a college student with no job, I don't have the money to call in a professional air conditioner guy to fix this, so I rather deal with it on my own....See MorePortable Air Conditioner Problem...A/C isn't working
Comments (2)My AC Isn't Providing Enough Cooling. Portable air conditioners are ideal for cooling small areas, such as bedrooms or living rooms, or for providing supplemental cooling in places central AC systems can't reach. Because they're small units, the two primary reasons for inadequate cooling are incorrect sizing and extreme ambient temperatures. The size of an air conditioner refers to its cooling power, not its physical proportions. Portable ACs are sized according to their BTU ratings, and if your portable AC has the wrong BTU rating for the size of the room you're trying to cool, its efficiency will be affected. A unit with too many BUTs will cause the unit to cycle off too quickly, while a unit with too few won't be powerful enough to affect the ambient temperature. To find out whether your portable air conditioner is the right size for the room it's in, measure the length and width of the room. If your room is oddly shaped, try breaking it up into smaller shapes like squares and triangles. Calculate the area of a triangle my multiplying the base by the height and dividing in two. Once you've calculated the area, consult our portable air conditioner sizing guide to see what size air conditioner will work best in that space. If you're on the cusp of two different sizes, always choose the bigger one. It's okay to have a little more BTU than you need, just so long as it's close to the correct size. On the other hand, if the ambient temperature is too high, it can also cause insufficient cooling. As portable AC units release cool air out into the room, they vent hot air from the compressor outside. This constant venting causes a pressure imbalance that pulls in warm air from the other areas, including adjoining rooms and the outdoors. Normally, if the room is properly sealed and all the doors and windows are closed, the air coming is never enough to overwhelm the portable AC unit. If there's a leak, or if the outside temperature is extremely high, the air conditioner may not be able to generate enough cold air to cool the room. Sunlight can also heat a room faster than your portable air conditioner can cool it. If temperature keeps rising, check for leaks and close the blinds. It may be enough to swing things the other way....See Moremike_home
