Wow!!! you have a real hate for people 555555

how does it dehumanise the air????! 

 

My my aircons only take the water or heat out?

not to dehumanise you are futher a little okay - mine takes some smoke away, absorbed by the condation water. 55 - lifted stuff comming up now -

The comfort level in the room is not only a function of temperature. Humidity levels in a room can make you feel uncomfortable. In D'light cool mode , the AC unit measures both temperature and humidity. In humid environments even at a cool temperature, humidity levels can be high, making occupants feel uncomfortable.

 

The D'light cool mode will make an assessment of both temperature and humidity and so even if the desired temperature is reached , the unit will continue to dehumidify until a comfortable index level is reached.

an aircon can't dehumidfy without cooling at the same time. but a hint to those who don't have units with a dehumidifying function is "reducing fan speed = increasing dehumidification".

 

lower fan speeds = lower temperature at evaporator coils = higher dehumidifcation.

Hey,

Check out http://www.lazada.co.th/shop-air-conditioners/

Then use youtube for reviews.... I have a samsung and LG both bought and installed at the same time and I can say the LG performs much better, as far as I am aware I do not think you can get your air con and dehumidifier combined? best off buying a decent air con and if you feel the need a separate dehumidifier but a dehumidifier may heat up the room as weird as that sounds.

LG all the way on your air cons though,

Cheers

Lazada is great for a lot of items, except............

Ones that need installation or ongoing maintenance.

Decide what you need, shop for the price range then choose a reputable full service shop.  You need to have only 1 person responsible for the whole deal.

AC mode vs. dehumidify mode question:

Daikin 18.5k btu inverter.  The AC works like a champ when in cooling mode at 25degrees.  But in dehumidify mode, it removes more water (of course) but also cools the room very effectively (with Daikin AC in dehumidify more, you cannot set the temperature).  

So my question:  is there any harm in using dehumidify mode for an extended period......let's say 6 hours or so?  Minor second question:  what mode uses more electricity......cool mode at 25 or dehumidify mode?

Thanks as always to the air conditioning experts on the forum!

No harm using "dry" mode.

Uses less energy in "dry" mode.

i'm not sure as far as an inverter model is concerned but a conventional unit uses definitely more energy as the compressor doesn't stop running and the fan of the inside unit is at reduced speed and even stopped (some Daikin models) to obtain lower evaporator temperature. the lower humidity level masks the reduced cooling capacity.

 

running extended time in dehumidification mode is no problem as long as the sensor works that controls any potential icing on the evaporator fins and then increases fan speed and stops the compressor intermittently. but if the sensor fails a serious problem could occur, namely "liquid hammer" meaning the compressor is not sucking gaseous refrigerant but partly liquid one which could lead to compressor damage.

The post I responded had a Daikin inverter (as do I).  My Daikin is 12K BTU and draws about 1.5 amps in "dry" mode (3 amps at normal operation)  even though the compressor is always running.  The inside fan speed is not much more than a poof but keeps our bedroom cool and dry at night makes a very comfortable sleep.

 

Just to say: whatever the type of AC, if the mfg. puts "dry" as one of the mode options and without stipulations, one should conclude that it is not harmful to use that option.

Thanks for the responses on running my inverter AC in dry mode.  FWIW......we used to have that off-odor smell in rainy season in our house.....but when we run the AC in dry mode for a few hours each day, especially in rainy/high humidity season, that problem is in the past.
