usually i use cool mode for around 1 hour+ then switch to dry mode, the temp on the remote is always 27c, the room remain cooled or even cooler when i use dry mode until i have to switch off the ceiling fan

but if i switch on with dry mode all the way it take longer time to cool my living room and i only use my aircond when weather is hot

~Right after my post above I tried myself, using Daikin Air Cond, to equate to coolness of i. Normal Mode 30- 28 Celcius, need ii. Dehumidify, also known as Dry Mode about 25 Celcius, while other electrical appliances usage are kept same throughout I tried both i. & ii. for strictly 1 month ~24 hrs/day each & recorded electricity bill, ii.'s more expensive by ~RM60.
Edit, typo, ii.'s more expensive than i. .

Correct me if im wrongg, so u use cool mode 28-30 celcius, but in dry mode u use 25 celcius? Why not set same temperature? 27-29 celcius maybe? 25 vs 28 is very different power consumption šŸ˜…šŸ˜…

As 25 Celcius highest Celcius to same coolness as Normal mode 30 Celcius.

Just wanting to get better understanding on the fungus part. mentioned that putting it on dry, helps to avoid fungus. does it mean setting it to cool, fungus would invade the space? not sure if i have seen fungus at home or office, though both is set to cool

fungus usually happens on indoor unit evaporator coil... this year CNY while servicing the AC unit myself, one unit was infested with fungus shaped like mushroom, it's disgusting... sad.gif

So using dry mode, my AC off the compressor for like 7 minutes and then it switched on, basically the conpressor runs for like 7 minutes off 7 minutes, on again after 7 minutes.

Does this give power saving compared to the compressor running fully in Cool Mode?

Interesting topic.
Stuffy is becoz of high humidity, or maybe too still or dead air.. not much air movement.

I dont really know how aircon work in dry mode.. but dehumidification or drying the air can only be done by having low cooling coil temperature.. coil must be below room dew point temperature for condensation to happen, thus moisture is removed from the air.
But the main energy consumption is usually at the compressor. Compressor is the one that make the coil cold, thus it need to consume energy.

Anyway, anyone care to share the data/ finding of this by sharing the setting on aircon, data taken from elec meter and room temperature?

If I’m not mistaken. In dry mode, the compressor indeed work for shorter time. But instead of continuously taking in moist air from the surrounding as in cool mode, dry mode only takes in a batch amount of moist air. The heat exchanging process then started but the coolant nor air is of continuous flow. As the heat exchange in cool mode is continuous while the dry mode is of batch, moist air is being cooled down to even lower T (perhaps to extent where coolant and air achieve thermal equilibrium) than cool mode does (heat exchange duration is short so T of air will not as cold as that of coolant). As in how energy is saved, not only the energy supplied to expand the coolant is less, but the energy supplied to compressed the coolant to the higher T is also less (as the T of coolant of dry mode is higher than that in cool mode, so less energy to increase the T back to the high T).

I think using dry mode saves electricity because compressor does not turn on to full capacity. The cheapest is FAN mode because the compressor does not turn on at al

tried dry mode for more than 1 year... cant see any significant changes to my electricity consumption.

I used to use Cool mode at 25°C on remote control.

After switching to Dry mode, had to increase the remote control temperature to 28°C. Having 25°C for Dry mode was too cold.

Living in a small Studio appartment. All walls and floor bricks and marble. Windows all airtight type.

My throat bit dry sometime thou, drinking more water now, which is good i suppose.

Aircon is running 24/7. Old YORK EcoKing model.
Electricity bill wise, Dry mode got decrease 25% vs before on Cool mode.

in my case dry mode can cool down the room and when turning the aircond off, the cold sustain..

While cold mode, the aircold is too cold and when turn off, it became heat and trap again...

Now only I realize something to do with the humidity..
