Re: fans that you load with water or ice water

we just bought one for the office to augment our exisiting a/c and we've been using (noon time) it the last 3 weeks. so far, its doing well, i just hate it squirts water every now and then. brand is Asahi, we got it from puregold.

Re: fans that you load with water or ice water

thnx magngyver for the reply

pero the one i am asking is the one na di nag squirt ng water. parang cold water passes somewhere n me fan na blows into it. so cold air labas. yng mahal ata na version call it evaporative water cooling

Re: fans that you load with water or ice water

junn2006...we are talking at the same product. The air passes-through a chamber where there is ice cooled water and then blows the air out of its vents. Maybe the unit i bought has a defect as it sucks and squirts some of the water out. Messy sa floor.

Re: fans that you load with water or ice water

Yes, I've had one that came from Singapore for years.

What this unit does is a vertically rotate a plastic 1 ft. wide wirey/meshy band w/c is underwater and constantly turns this around thus wetting it, then a fan motor passes air through it cooling the air 1 degree and passing it out the vents.

If you put ice water in the container, then the air will be even cooler !!

You just have to constantly clean the containers and clean the rotating mesh to guard against mold and calcium build up.

If you do not have an aircon, this is the next best thing.

Re: fans that you load with water or ice water

The only problem with this kind of cooling is that it really raises the humidity. Using this with an aircon which of course reduces humidity by condensing it in the evaporator coils will alleviate the problem.

Re: fans that you load with water or ice water

I've seen this units being used in Tiendecitas. I know a cheaper supplier which I visited the factory/ office few months back. Supplier is located along P. Guevarra. Coming from Ortigas, take Wilson then right turn at P. Guevarra. Before the traffic light the shop is at left side.

The Users manual says, when use in cooling rooms, the unit shall be place near an open window. Room should be properly ventilated to avoid increasing the humidity. I believe the unit which is as high as 6ft is about P8000 during the time.

Hope this helps.

Re: fans that you load with water or ice water

Yup, Willie, that supplier sells evaporative cooling fans made in China or Taiwan I believe. Quite expensive considering the quality.

The one in Tiendesitas is a simple misting fan like the 'mistercool' website in my first post here !

sorry po for misunderstanding your post

Re: fans that you load with water or ice water

so if i dont have budget for an elec fan, the next best thing to an electric fan is to buy one of this?

tama ba?

mdyo alaws tyo ngyon e. ska mahal din kuryente pag naka aircon lagi.

Re: fans that you load with water or ice water

Guys,

The evaporative coolers will work best if the relative humidity is low and fresh air is always available meaning air changes are frequent. These units work by evaporating water into the airstream. We all know when water evaporates or changes phase from liquid to gas, a lot of heat is absorbed thereby cooling the air but also humidifying it. If air is already 100% RH because of ambient conditions or because there is no air change in the room then this will become an expensive electric fan. No cooling effect anymore.

A big mistake is to use this units in airconditioned rooms. Aircon units cool the air and at the same time remove moisture from the air that's why there is water coming out of the A/C. Airconditioning is the process of controlling both the temperature and humidity or moisture in the air. Now by introducing evaporative coolers in an airconditioned room, the moisture introduced by this devices will eventually be removed by the airconditoners. This will unneccessarily burden the A/C's more. Net effect is worse. Better leave the cooling to the A/C's and use an ordinary fan to distribute the air if there are dead spots or hot spots.

Re: fans that you load with water or ice water

If you want to save electricity, just alternate the use of the air-con and the evaporative fan.

I believe some companies are doing this by shutting off the aircons at lunch and switching on these units.

Re: fans that you load with water or ice water

The wilcon builders supply here at Libis has a giant evaporative cooler working inside their airconditioned warhouse. I think it is a waste of electricity.

Re: fans that you load with water or ice water

I got one too, the Asahi brand. It works fine but it works well in small & confined spaces (no A/C) only. The wind it produces from its blowers is quite limited compared with any electric fan & maximum cooling effect is best felt about 2 feet (or less - depending on the heat) away.

Re: fans that you load with water or ice water

junn2006, yung sinasabi mo bang fan nilalagyan ng tubig, water circulates inside parang may radiator, nabibili sa mga mall. i suggest not to buy it, i have an electronic shop, madalas dumating sa shop yang, burned out ang motor due to moisture. pagmay warranty pa ni-reject ko kaagad, kahit palitan mo ng motor, it's the same thing.
