An air conditioner works as a heat exchange circulating air through a cold evaporative coil, Evaporative air cooler works by evaporative cooling by pulling in air from outside through a wet pad. There is a fan motor & a water pump which are only two components with moving parts to work continuously. So I would suggest you turn an air cooler on whenever required. 2 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Nancy smith 0 Questions 6 Answers 0 Best Answers 47 Points View Profile Nancy smith Added an answer on July 20, 2020 at 6:46 am As long as you are in the room you have to keep the cooler on. If you are thinking that if your room is a little cold then you can close it, it is not so. As soon as you close the cooler, after a while the room will become warm again. This is my own thought. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
