Is it true that if you wet the rear of your window type A/C with water it would help it produce much cooler air inside the room? ???
Re: Window Type Aircon
I know the answer is "yes" within certain limits but sorry to say I slept through my thermodynamics so we'll have to get the MEs to give us the whys.
Re: Window Type Aircon
In that case, why don't they invent a gadget to splash the water condensed in the evaporator (which is relatively cool) to help cool the aircon's condenser? This should save power.
Re: Window Type Aircon
Several problems exist.
1. You need a constant supply of water since the most of water will evaporate away.
2. The system will require regular cleaning since the water attracts dust, dirt, insects, and molds. (If you dont clean it regularly, you have an aircon that blows cold air but also introduces fungi, bacteria and viruses into your room)
3. There is a danger of the water corroding the metal and rubber parts (especially if you use rainwater)
The evaporative cooling effect of water may not be as significant as you think. It would be better to just mount the A/C in a location where it has access to cool air to circulate around.

Thank you gentlemens, appreciate all your inputs.
Re: Window Type Aircon
Old 70's era airconditioners of the local "Air Con" brand used to have a little 'scoop' in each blade that splashes the residual water the accumulates in the bottom pan.
Before, the proper angle is important in mounting the aircon unit so that the bottom pan has the right amount of water and the overflow empties out the tube at the back.
As to the mold, bacteria etc., I guess the fact that the water is always renewed (circulating), this problem is minimised. Remember this water is 'distilled' water constantly renewed.
Then, cleaning aircons during those days were done more often.

Re: Window Type Aircon
i believe lalamig nga sya. di ko lang alam kng may side effects.
sa cars pag medyo mainit aircon, i wet the condenser fins.
Re: Window Type Aircon
I've learned that the main problem is that the dust in the air causes the wet condenser fins to become dirty more quickly. But this can be solved by more frequent cleaning.
Re: Window Type Aircon
Guys,
My National brand 1 hp aircon has the option to allow evaporative cooling at the condenser. One has to do is to plug the condensate drain and a pool of water will form and the condenser fan will scoop the water and spray it to the condenser coils. This is good because one has not to worry about piping the water away and it will make your aircon operate more efficiently.
If we remember our psychrometry, there are two temperatures that we can take; wet bulb and dry bulb. Wet bulb is always lower than dry bulb except when relative humidity is 100 %. Now when one sprays water at the condenser, condensing temperature can approach the wet bulb temp which is lower than the dry bulb temp. This will give us a lower condensing pressure (less compressor work) hence lower electricity bills. The downside is that the coil might require frequent cleaning since water and dust together can clog the coils faster.
Industrial plants use evaporative condenser for their refrigeration plants for the hope of better efficiencies. Big plants especially those with abundant water supply use this type. Air cooled condensers are used when water is scarce or of very poor quality.
Re: Window Type Aircon
I have a Condura like this
It about 3 to 4 years and cleaned it 3 to 4 times. I've ask this to the service personnel who cleaned my A/C. I ask why this model is always have leaks. I discovered na naiipon pala yung mga water sa likod to produced more cold air at pag walang water madaling masira. The problem is kinakalawang yung lower back part ng A/C (evaporator ba tawag dun? Anyway kaya hindi sa mismong dish tumutulo yung water.
Napansin ko you can clean your A/C by yourself. dapat may compressor kalang. keysa sa 500 na cleaning fee. My A/C right now have vibrations if set to High fan. sabi nila sa bearing ng motor ang problema.
Re: Window Type Aircon
Uwak18,
Baka kaya tumutulo yung aircon mo kasi hindi naka incline yung unit mo. Dapat para magdrain sa likod and tubig ang unit ay naka slope or naka pababa yung bandang hulihan ng unit mo. This will allow the condensate formed at the evaporator to slide down the bottom and out of the unit at the rear end where it is outside of the house already.
Re: Window Type Aircon
ganon pa rin ba hanggang ngayon? kailangang nakatilt pa rin ng bahagya yung aircon para lang magflow yung tubig?
Safety first - always wear face/eye/ear/hand protection as a minimum.
