Tip & How-To about Dehumidifiers

Dehumidifier VS. Air conditioner

A dehumidifier is basically the same thing as an air conditioner but both coils (condenser and evaporator) are in the same unit meaning a dehumidifier exhaust warm air in the same room it is in. running a dehumidifier would make an air conditioner run more because of the warm exhaust, when you run an air conditioner it acts like a dehumidifier and dries the air. As far as saving energy it all depends on the size of the AC and dehumidifier and the size of the room. If you want warm dry air, use a dehumidifier; if you want cool dry air run the AC but not both.
How do all these parts fit together to pull moisture from the air? It's fairly simple, but very effective:

  1. A fan collects air from the surrounding area and pulls it into the dehumidifier.
  2. As the air passes through, it comes into contact with the dehumidifier's cooled coils. These coils use condensation to pull moisture from the air. The collected moisture remains on the coils and drips into the dehumidifier's reservoir.
  3. The dehumidifier reheats the air and exhausts it back into the room.
A dehumidifier usually has a removable plastic bucket for are reservoir; most buckets also have a place where you can hook up a hose so the collected water can drain straight into a floor drain or pump. This frees you from having to remember to dump out the water. But don't worry too much about the reservoir overflowing -- most dehumidifiers also have an automatic shut-off. If you're using a dehumidifier in extremely moist conditions,however, or if you need to keep your dehumidifier on all the time, you should look into a unit with a built-in condensate pump, which regularly pumps water out of the unit's reservoir rather than simply relying on gravity to empty it as a hose does.

It will no longer collect water...fixable?


They are basically a refrigeration unit that draws the moist air from your home and condenses it on the evaporator coils. If you are getting no water, it could only be two things;

1. there is no moisture in your house.
2. the refrigerant gas is low.

Using as heater and unit is blowing cold air


A heat pump is an air conditioner that reverses its refrigerant flow. In the cooling mode, the evaporator is cold to the room and its condenser is hot. In the heating mode, a valve reverses the refrigerant flow and makes the evaporator warm and the condenser cold.

Air conditioners remove the moisture from the air, and so does a dehumidifier. Does running a dehumidifier make the air conditioner run less? Does running the small dehumidifier save energy in that the larger air conditioner runs less?

Unit runs but no water collects in bucket. Unit is over a year old and has run continuously that whole time. Up till now it has performed beautifully. Is it just worn out?


Hi;
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing

Dehumidifier frosts up


A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely. 1) Be sure the unit is set far enough from the wall so that airflow isn't restricted. 2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
