Fan control explanation

I just have a question. When you put a window air conditioner on "fan only" does it bring in air from outside or just circulate the air in the room? Thanks.

Mostly it just circulates air in the room. However, if you use the fresh air setting, it will bring in a little outside air.

Why are my outside windows are wet


Your windows are wet because of "dew point" google it for an explanation. Air conditioner settings are generally 21 degrees Celsius but energy saving temp setting should be around 24 degrees Celsius . I would hazard a guess you have yours set a lot lower to get condensation on your windows maybe 16 to 18 ?

Where can I get a manual for my Emerson Quiet Cool Room Air Conditioner? Not sure the model, but these #s were on outside of box: 10DC93 784040B OE21M N14421, is on a little sticker on the right...


Let see if I can help. The numbers don't come up so we'll just try your information.

Exhaust - should be closed when using for Air Conditioning
Energy savings turns the fan off with the compressor when set for Air Conditioning
Fan Only means just that (no Air Conditioning)

Fan speeds Quite same as low, Norm same as medium, Super same as High
Temp settings, what the thermostat senses before cycling compressor.

Poor cooling


cold air is made by refrigeration in the air conditioner. If the unit is low on the freon charge then you have a poor exchange and poor cooling. I have gotten the units to work better by putting a little water on the outside exchange coil. by bringing the temp down on the outside coil you get a better exchange and better cooling. I used a small copper tube with about 10 real small holes in it to drizzel just a little bit of water on the outside part of the machine. the fan cools off the outside coils off and gets a better exchange bringing down the temp of the air coming out of air conditioner

CAN A SPLIT SYSTEM BE ALTERED TO BRING IN FRESH AIR


No sorry the air is circulated from the room and sucked in front the top of the unit. the only way to get fresh air around is to open up windows then put the unit on fan only.

Does a window unit have to be in a window? can i put it in the house?


A window unit is designed to have the side with the controls in the space which is to be cooled and the other side to be outside. If you simply put it on the coffe table, blowing at you, you may feel cooler for a little while, but the heat of the fan motor and compressor added to the heat from the outside coil, will raise the temperature of the room.

Best bet is to put it in a window or to have a sleeve made for a through the wall installation.

Emerson quiet kool wall air conditioner. Should vent be open to remove humidity?


No - opening the vent will allow unconditioned outside air into the space and add to the humidity load.

Think of it like your car's A/C - when you put the controls to "Max A/C" the system recycles just the air inside the car and doesn't use any outside air. When the control is set to normal A/C, some outside (fresh) air is brought in.

The same thing is true for a window A/C unit. Keeping the vent closed will help the unit de-humidify and cool the air more quickly.

Is it good to close the vent or have it open


Hi,

The vent will bring in outside air while running. If you are use the cooling keep the vent closed for the best performance.

If you are just using the fan only for air circulation and it is mild outside you can open the vent for fresh air to be pulled into your home.

Exhaust fan


No, the air conditioner fan moter - basically 're-circulates' the air in a space - while an exhaust fan takes air from the space and puts it outside to the atmosphere.

Plus an exhaust fan is considerably cheaper than an Air Conditioner.
