I have an open floor plan design with the recreation room slightly below
ground level. It used to be humid in summer
with central air in the house to the point that carpet was becoming wet in
places. Will dehumidifier help?
Will it work againts the airconditioning heating house, or will it help
cooling it (it will lover the humidity
thus increase evaporation inthe house and evaporating water will help cool
On a purely temperature basis, it will raise the temp. But
the decrease in humidity will add to the comfort. Though I'm
a little surprised, I'd have thought with central A/C that even
a room "slightly below ground level" would never be humid enough to
have a wet carpet. Sure you don't have water seeping in from
Well humid air will take more energy to heat because it can hold more
heat. Dry air is easier to heat, but it holds less heat.
Dry air takes less energy to cool since it cant hold as much heat as
But its all relative. 75 degrees and dry can feel just like 70 degrees
and humid. They both can be holding the same amount of energy.
Neither. What you feel is not the 'temperature' around you. What you
feel is the rate of heat loss to your surrounding environment. We call
that temperature but its not the same thing.
Lowering the humidity in the house will be helping the air conditioner.
it means the air can hold less energy and will thus be easier to cool.
Simply lowering the humidity in the house will make the house feel
cooler automatically (though it wont be reflected on the thermometer)
perhaps in terms of energy, but not in terms of comfort. If you can
turn your A/C thermostat to 72 instead of 68, you may save energy.
Given the difference on energy between 68 and 72 is bigger than the
energy used by the humidifier.
But the a/c already does its own dehumidification, so it really needs to
be tested. I would suspect A/C on its own would do the job, but I live
in relatively non-humid area.
it will work both for and against the A/C
for it, in humidity maintenance
against it on heat production
overall, it will same you money and make you more comfortable, and cause the
A/C to run much less overall
get a dehumidifier
