What is the Difference Between “Cool” and “Dry” Settings for an A/C?
What is the Difference Between “Cool” and “Dry” Settings for an A/C? If you are asking this question, you are also probably wondering how to use your air-con efficiently? And when is the best time is to use cool or dry settings? Why does water drip from the air vent? Now I am no air-con expert but I had those same questions and I want to share the answers I found with you albeit in my own words in non-technical jargon. (FYI, I use a split type Panasonic air-con in my room which I’ve had for more than 2 years.)
First off, what is the difference between “cool” and “dry” settings for an A/C?
I’ve read through countless blog posts, forums, etc… and here is the gist of the answer to the above question. Both cool and dry settings removes water in the air. In essence, both settings reduce the humidity of the room which makes you comfortable and feeling cool. Now the difference is this. The cool setting does a little bit more by cooling the air until it reaches the desired temperature as set by the user. On the other hand, the dry settings just drys the air (dehumidifies the air…) and when humidity is brought down to a certain level, the A/C stops thus saving energy.
With that knowledge, we can devise a simple plan on how to use the A/C more efficiently and bring down energy billing costs. If temperature is really high (very hot), then use the cool setting. It dehumidifies the room which is good for humid countries (e.g in the tropics) and brings the room temperature down as desired. On the other hand, if the room temperature is fine but it is a bit humid that day, then just use the dry setting. The A/C will bring humidity down and you will feel cooler because your body can now release more heat thus cooling you. Lastly, if it is simply cool that day and want it just a little bit cooler, use an electric fan!
After awhile, probably after a few years of using your a/c unit, water starts to drip down from the indoor a/c unit itself and not drain down the proper channels. This is due to the fact that the drainage is dirty water cannot sift through it properly. To solve this problem, simply clean the inside of the water duct(this is my own term referring to the pipe which drains the condensed water out of the room…) and voila your a/c is as good as new.
Now, as I said I am no a/c expert and the information above is how I understood the various articles and posts I read online about A/Cs and their settings. If I get them wrong, please correct me via the comment section below
