Dehumidify - Air Conditioner & Electric Space Heater FIGHT!

After looking at various de-humidification processes am finding that I can drop humidity by having my small electric space heater work to increase temperature, while having my Air Conditioner work to cool. Just needed to find the sweet spot between the two independent thermostats so they do not come on constantly. Result is about 70F and 55% humidity.

So far it feels comfortable. In Florida winter (Orlando) and humidity is high outside.

Alternatives to above?

1) Use DAMP RID in strategic areas. Likely will do this anyway as its good policy to keep the humidity down and reduce chance of mold.

2) get a good Peltier Junction dehumidifier device. These suck heat out of the air with electricity (inefficiently, and humidity will condense). Very quiet but effective in smaller spaces and only at certain humidity. Think they can drop humidity to 60% or lower, best case; and only over several hours of the day. If you get one, get the one with the largest capacity.

3) Buy a refrigerator dehumidifier device (uses Freon). These can drop humidity faster and dump more humidity out of the air (70 pints a day for some). Many feel they need this if they do several air exchanges (open doors) during the day.

Still we like to have some fresh air exchanges, so we do turn off all devices and just deal with humidity on occasion with strategic fans.

    And the plus is you would gain more dehumidification with less use of energy.

    This is the way a real dehumidifier works. The dehumidifier is simply an air conditioner with no outside "vent".

    An air conditioner cools the air (which causes condensation the same as a cold can of beer get wet on the outside) then it moves the hot air to the outside of the room to the compressor this is outside. A dehumidifier simply has the compressor inside the room.
  • Me thinks you are over-thinking this. An air 'conditioner' conditions the air by REMOVING moisture from it and then cools it by blowing inside air over the cooling coils. When I run my a/c in humid conditions, the water (condensate) is quite visible as it runs off the roof and down the side of the motorhome. If this isn't happening on your unit, I would suspect a problem with the a/c. But since you say the air temp is 70 degrees, I would think the a/c is doing its job. If you feel the a/c is not removing the moisture sufficiently, I would invest in a small dehumidifier.

    As for the storage spaces that do not receive conditioned air, Damp Rid would be a solution.

    Also, today's refrigeration units of any kind no longer use Freon.
