Atrecord Supersonic October 28, 2022 Share October 28, 2022 Searched through and found couple of very old threads on this, but am thinking whether with new products (new tech?) would have changed anything. Saw these evaporative air coolers that's not an aircon, but uses water and blow out air, that claims to reduce surrounding temperature by like a few degrees... Has anyone used this before or has any knowledge/information of whether this will really work? Am considering getting one to put in balcony so that on the days when i WFH, can sit in balcony to work. As it is, on a hot day (>31 deg) even with fan at full blast, it's still quite unbearable. am wondering: - really will reduce temp by at least 1-2 deg? - will it be very noisy - does it consume lots of electricity (c.f. fan and aircon) Anyone knows? Thanks... ↡ Advertisement Link to post Share on other sites More sharing options...

Hummer 3rd Gear October 28, 2022 Share October 28, 2022 Don’t bother. One of my regrets buying one. SG already very humid this one makes it worse. no effect in lowering temperature. 11 1 Link to post Share on other sites More sharing options...

Thanks... I had a used Honeywell brand before. It is kinda big and bulky hence(not like the picture) I sold it to a friend. Noisy: Yes(for a big unit). Depending on what fan speed you set. Consume power or not I cant really tell, definitely less compared to aircon. Since you use during the day or off peak, anyway gotto look at what energy plan you sign up. Imo at the balcony, definitely hot cos of our climate. Looks and sounds romantic when ppl say work at the balcony, in Europe ok but not in Sg. And it depends on where your balcony is facing. Cools like a fan. I didnt use a thermometer to measure. I rather have a ceiling fan. It is quieter and it is more effective than any standing fan. 4 1 Link to post Share on other sites More sharing options...
Loki Supersonic October 28, 2022 Share October 28, 2022 If using on balcony maybe can consider a fan which sprays out mist for cooling? That might work 6 Link to post Share on other sites More sharing options...

Estrangable 5th Gear October 28, 2022 Share October 28, 2022 Evaporative cooling does not work in this region. Period. The only reason why these machines feel cooling is because you are in an air-conditioned shop or mall. From wiki - "Most evaporative coolers are unable to lower the air temperature as much as refrigerated air conditioning can. An evaporative air cooler in a closed room, without any connection or opening to the outside, cannot lower the room temperature at all by the physical law of conservation of energy. It might even add to the room temperature by its electrical components. " If you want to waste your money on these.... why not donate to charity. 1 Link to post Share on other sites More sharing options...

Waste money on blinds as well. The balcony here is not suited for anything except to dry laundry. ↡ Advertisement 2 Link to post Share on other sites More sharing options...
