Staying Cool During High Humidity & Heat In Vietnam

OceanBeach92107

Stay Cool and Lower Electric Bills:


It's currently 34簞c outside in H廙i An but "feels like" 43簞c.


In our house, using only the dehumidifier setting on our air conditioner unit, the temperature inside (with doors/windows closed) is 29簞c AND it "feels like" 29簞c.


That's 14 degrees Celsius cooler, with electric fans providing a nice, refreshing breeze and making it feel even cooler than that.


Save a ton of money on electricity and avoid the ill health often associated with air-conditioning use by using a similar solution for yourselves.

Sound advice. Keeping humidity low inside the house has a lot of health benefits. Keeps away mold and strange smells. I have mine constantly turn on in the winter and summer in Taipei. When I move to Saigon I will buy a few dehumidifiers to keep around the house too. For me it's just as important as a good AC. I normally go for machines with a huge tank so you don't have to refill often. If you can afford it, have a built-in unit mounted on your ceiling when you renovate your place.

As an update, the a/c unit in one of our bedrooms went on the fritz and needed to be replaced.


I then learned that the 5-year old Toshiba a/c unit had a dehumidification setting but really wasn't doing it efficiently (apparently never had the ability to do so) and was overheating when I used it full time throughout monsoon season and recently as heat & humidity climbed, with less than excellent results.


Most stores here no longer carry air conditioners but instead are selling 1-way "inverters" (cooling only; a 2-way inverter also heats).


Inverters (also called "Heat Pumps" or inverter heat pumps) are much more energy efficient than air conditioners AND are also much more efficient dehumidifiers:



So, it would seem that if you move into a place with inverters, you shouldn't have any need for additional dehumidifiers.


The inverter dehumidifier function can't quickly cool down a room, but rather does so insidiously, so to initiate cooling in a room, start by running the cooling function until the desired temp is reached, then switch to the dehumidifier function and it should maintain a comfortable atmosphere in the room, with perhaps only a fan needed to provide a gentle breeze.

I have posted this before but please bear with me if you have been reading here forever. When I first arrived in Hawaii with the Army, it was January 1970 and I thought it was the hottest, most oppressively humid place I had ever been. The office that I worked in was not air conditioned but it was close to the ocean. The next January I was sleeping under two blankets.


Later while awaiting what was then called a levy to Vietnam that never came, the thing I feared was not the bullets but the heat and humidity based on the descriptions of 'lifers" in our office. What I found years later was that the temperature and humidity in Vietnam was very close to that in Hawaii, except the country lacked the trade winds to assist with bodily cooling. However, after a while you stop noticing. Follow OB's advice and avoid using the A/C if you can.

Grand advice from all.

Since arriving here, I've been able to incrementally raise the setting on my air conditioner. Then and now I still use it only in the bedroom at night (and occasional naps).

When I arrived in 2017, the default setting was 23C, something I now find much too cold after 6 years here. These days 26 or 27C suits me fine.

Bear in mind that I originate from a region referred to as , so for me tolerating 26 or 27 is a real milestone :)

Never thought I would say this, but there are times I truly miss the ice and snow.
