Question about Danby DPAC9031 Silhouette 9,000 BTU Portable AC Air Conditioner

1 Answer

Dehumidify mode also cools

When operating the unit in dry (dehumidify) mode, it blows cold air. Yes, dehumidification works by passing room air over cold so moisture condenses. But other dehumidifiers mix warm air from the compressor with the cold(dehumidified) air that blows into the room. The DPAC9031 instead exhausts the warm air from the compressor to the outside of the building. That's fine on hot days, but when the room is already 70 degrees Fahrenheit, and the dehumidifier needs to run for two hours to get the humidity level down, the room also becomes very cold. I'm wondering: 1) Is my unit working as designed? 2) If yes, does someone sell a hose adaptor for this unit that will divert part or all of the warm exhaust into the room? 3) If no, how can it be fixed so that dry mode doesn't also continuously cool?

Ac exhaust fan

Yes for dehumidifier, no for heat mode. In dehumidifier mode all the unit does is takes air in, runs it through the evaporator (cold) coil and the back through the condenser (warm) coil discharging dry, slightly warmer air back into the room. In heating mode however if you don't vent the exhaust there will be no heat produced. Warm air will come out the top but cold air will also come out the exhaust (essentially, in heating mode all it does is operates as an air conditioner in reverse. Hope this helps.

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.

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.

Blows very cold air during dehumidify mode.

se this fact: God bless you
air conditioning system cools but does not dehumidify the room. The most common cause of inadequate dehumidification by an air conditioning system is the installation of a cooling unit which has too much capacity, or is "over-sized" for the space it is being used to cool. What happens is simple:

If an air conditioning compressor unit is oversized (too many BTUH of cooling capacity) what happens is it cools the room so quickly that the system does not move enough total volume of air across the cooling coil to remove much moisture before the room temperature has dropped to the A/C cut-off point.

In other words, an air conditioner needs to run longer, and move more total volume of air through itself to drop room humidity than it does to just cool the air. So "bigger" cooling capacity or higher BTU capacity for an air conditioning system is not necessarily better, and it can actually be a problem.

My Haier 7000BTU portable AC unit is blowing hot air into the room from the back. We have the drain hose in and draining, so what might be the problem?

The drain hose is only to be used when the unit is in Dehumidifier Mode. In AC/Cooling Mode, there needs to be water in the tank to keep the coils cool. It is not recommended to use continuous drainage in AC Mode. My personal recommendation is do not operate Cooling Mode & Dehumidify Mode at the same time. As the dehumidify mode generates heat. Not something you need to be doing when you're trying to cool the room.

Hope this helped you and thanks for choosing FixYa.

My dehumidifer collect water but the fan blows hot her so it makes the room hotter

This may be caused by running the unit in continuous mode, rather than timed mode. The heat is generally is generated when the defrost mode cycles on, to defrost the cooling coils. This happens more frequently, if the air space around the unit is obstructed or it's operating in a temperature range of 40 to 60 F. Cleaning the air intake filter at least once a week, can help solve this problem, too.

Maintain a minimum of 12" free air space around all sides of the dehumidifier. Use a timed mode rather than a continuous mode. Make sure the room is within the proper operating temperature range and clean the air intake filter weekly.

Hope this helped you troubleshoot and solve the problem.

Mr slim unit in bedroom 9kbtu - room 11x12'- is humid, awful

Lets clarify. DRY mode only dehumidifes that air and does not cool. Cool is used for cooling. Dry mode doesn't normally have temp control; it is automatically set by the unit. I think 9000btu is a big unit for the room; it is overkill. I would switch to a 5000btu unit. it cannot be fixed and the BR unit needs to be uninstalled and the new unit needs to be re-installed. The price of commisioning, de-commisioning and new unit is something in which you will have to pay.

Ice keeps forming on top of my lg dehumidifer

MOst likely the room the dehumidifier is operating is is too cold for proper dehumidification to take place. Try warming up the room and I believe then your dehumidifier will work fine.
