Sometimes it blows out warm air warm enough to warm an entire room, yet at other times is blows cool air that can kkep a room cool. I want it to blow cold at all times. how do i do that?


dry air feels cool on the skin

moist air feels warm on the skin

this is why the perceived temperature of air from unit changes

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.

How do you clean the filter


In order to look up the filter change procedure I would need the specific model number. However, filter changes or washing should be done regularly. Look for a very simple lift-out design that is washable in the kitchen or laundry sink. Soak in soapy water and rinse with spray nozzle.

As for the symptom "Blows out warm air" this is expected. The dehumidifier is less than 100% efficient, meaning that the energy that is used produces heat in the exhaust air. A 100% efficient design would still send all the heat energy of condensation (endothermic phase change) into the exhaust air. You should expect 1072 BTU per pint (1 pound of water). This is far more than the heat of crystallization (144 BTU per pound of ice) and therefore much more sensible when you feel the discharge air from the dehumidifier. Dehumidifiers typically operate in basements to both warm and dry the area where a sump pump may be operating to remove the water that seeps through the foundation. A dehumidifier is not a good idea for warm areas of the house. This will decrease the efficiency by increasing the temperature differential needed to get the evaporator coil below the dew point to cause condensation. The condenser coil will be much hotter than expected if the unit is operated in a warm humid room. Only air conditioners which discharge condensate and exhaust air to the outside of the structure should be used to cool a room.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.


It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

MY dehumdifier is blowing warm air ,Is there a fitler that needs to be cleaned and how is this done ? Model 3fdl5051 50pints


It's not unusual for a dehumidifier to blow warm air. As it may be in defrost mode. Even so, they still blow warm air.

The model number you furnished is slightly helpful. Knowing what brand it is, would be even better.

Never-the-less, the filter should be located behind the front louvers of the unit. Turn the Master ON/OFF Switch to OFF and unplug the unit. Remove the water collection bucket and look up inside the bucket holder, just behind the front louvers. You may see a plastic pull tab handle. If so, that's the filter frame. Pull it straight down and out.

If you didn't find it there, look on the right hand side of the unit, just behind the louvers for what looks like a a flip open door. If you see that, flip the door open and remove the filter.

The filter can be cleaned using a vacuum cleaner or if it's really dirty, wash it in warm water and dish washing liquid. Thoroughly rinse and allow to completely dry, before reinstalling it. NEVER operate the unit without the filter in place.

Hope this helped you. Please let me know. Thanks.

I have a Whirlpool dehumidifier model AD050SG0, is it supposed to blow hot air out of the back of the unit?


A dehumidifier is a 'de-tuned' air conditioner. Its job is to remove some of the heat from the air, causing a temperature differential which in turn should make the warm air give up some of its moisture ... just like a AC unit.

To understand the operation, you must accept that you cannot cool anything ... you must remove the heat from it. The heat (energy) must go somewhere ... in the case of a dehumidifier, it goes back into the room. Oh yes, also contributing to the heat is the electric components you are running ... the control boards, the compressor and the fan ... all use power and thus, give off heat.

Should there be heat coming out of the unit? ... yes, if it is running. Don't get mad ... these are things you probably learned in 6th grade science class - relative humidity - heat differential - properties of energy - etc.

My Danby DDR586R dehumidifier shouts hot air, it was shooting cool air before, what can the problem be?


Here is Danby's official response to a similar question on their FAQ page for Dehumidifiers:
https://www.danby.com/faqs.php?cat=12

Q) When the dehumidifier is operating, is it normal for the expelled air to be quite warm? We find that the dehumidifier is warming up the room noticeably (a finished basement).

A) The warm air that is being expelled from your dehumidifier is normal. When the unit is dehumidifying the compressor is working which causes the compressor to become quite hot. In order to avoid having the compressor overheat, air is drawn by the compressor at a rapid rate and the heat is then transferred to the air which must be expelled from the unit. The warm air will stop shortly after the unit has reached the desired humidity. This warm air should not change your room temperature by more than a degree or two.

Warm air from side vents..


If your dehumidifier is one that runs at colder temps so it does not ice up, it will have a heater in it to prevent this. That is the warm air you are feeling.

Dehumidifier freezes up


Most dehumidifiers need warmer air to work properly. The temperature in a basement is usually 60 - 65F; too cool for standard models. You could buy a "basement" dehumidifier. They're designed to work at lower temperatures; some as low as 40 F. Costs are about the same as a standard dehumidifier; you just have to find it.

For a cheap fix, try this; it seems to be working for me.

Since the condensate coil (the one icing up) is cold, the air entering it is too cool and the condensate frosts up the coil. Additional condensate freezes to the frost and before you know it, you've got a block of ice. Since the air coming out of the front is very warm take a large piece of cardboard around 6' x 3') and form a V. Placed it in front of the dehumidifier so it channels some of the warm air back to the rear where it warms the moist air up before it hits the cooling fins. It's helped keep the ice down.

If you want something attractive, any screen that redirects some of the air back to the rear will work. Just leave the top open so it doesn't get too hot and the some of the drier air gets out into the room.
