Posted: Wed Aug 02, 2006 2:17 am Post subject: Is my air conditioner "sick"? |
|
|
I don't think my air conditioner is working properly but I wanted to check with people who know more about these things than I do before I complain to someone. (There isn't a single English speaking person at my school these days to ask about this and I don't know anyone else in Korea.)
The AC unit is a high on the wall rectangular type with all of the mechanics in a closet that gets really hot. Although I have it set for 18 and have it running most of the time, the temperature indicater on the AC unit always reads between 25 and 29. It does blow cool air...but seems to work more like a fan than an air conditioner. Surely, this can't be how it's supposed to work since I have a small place and the only area that is relatively cool is the space that's within ten feet of the air conditioner.
Thanks ...in advance. |

Can you vent the heat exchanger to the open air (open a window in the closet) ?
It sounds like the ambient temperature in your closet may be too high and it can't cool off the system any more. It can only pump so much hot air into the closet and then the closet gets so hot that it can't make it any hotter.
I had a similar problem when I was living in a villa. Opened the window behind the aircon mechanics and it worked fine after that. Got the room down to 18 with no problem and much easier on the electric bill too.

Bam@()#*@ He nailed it right on the head. The same thing happened to me (believe it or not). They closet where the compressor is has to be ventilated. If not, the A/C won't cool properly. Once I opened up the vents in the closet that lead to the outside, everything worked peachy king. As a matter of fact, it's about 20 degrees celcius in here right now. AHHHHHHH.

ttompatz and cubanlord, thanks for the replies. I looked in the closet...no window there. Everything is too hot to check for vents at the moment.
I did open the closet for a few minutes. I thought that doing so might cool everything down. However, the temperature indicator soon shot up to 31 degrees. So, I closed the closet door again and now the temperature is 27. I'll turn off the AC for a few hours overnight and check for vents when it's cooler in there.
There is a service number in the closet. I may have to contact one of the Korean teachers who speaks English and ask him to talk to the service company for me. |

This may be asking too much, but would you mind taking a picture of the whole enclosure and posting it? |

I managed to take pictures and get them onto my desktop but I can't figure out how to post them on this site. Could send them by email if you want to be bothered....unless there's a simple explanation for how to post them here.
Since my last post, I ventured into the closet again and found that there are vents. They've been open for half an hour but the temperature hasn't dropped. It occurred to me that maybe there's a problem with the way I have the remote control set up (took a picture of that too). |

In order to post pictures on dave's, you have to have a host site for the pictures. http://www.photobucket.com is easy to use and quick to set up. Once you do so and upload the pictures, just copy the entire line that says Img src = and past that in the body here. Your pic. will then pop up.

DUDE!!!!!!!!
That's your problem right there!!!!!!!!!!!!!! You have two large units in an enclosed space producing a TREMENDOUS AMOUNT OF HEAT!!!!!! There is NO WAY you can get your A/C to cool with it like that. I don't care what they say (I was a property manager for 4 years before coming here). Trust me, this is my strong suit.
See the barely visible vents on the right wall in the closet? It's sealed off by a huge pane of glass. You will have to remove both a/c compressors/units and remove the glass. Then, open those vents. That heat has to get out of there or you will never have cold air blowing out.
You'll need to speak to your apt. manager about it. Here is a picture of mine unit:
Notice that I even have an extra fan in the closet for the really hot days. I use it to push the hot air out of there through the vents.
My friend, you have TWO units in an enclosed area. I guarantee that is your problem. Whoever installed those units in there obviously didn't give to flying hoot nannies about anything; they just wanted to hurry up and get the job done instead of doing the job correctly (or they really are ignorant).
Let me know how everything works out. I'm glad we found the problem. |

Thanks cubanlord!!!
I knew something had to be wrong--especially after opening the vents didn't seem to make much difference. |

Dude, who's compressor is that? One is yours, who's is the other?!?!??! Get that crap out of there...or....put a fan (like what you see in my picture) and turn it on to blow the hot air outside. |

Get the AC guy to come back and setup a bracket outside the window, on the roof, or somewhere below your apartment. The intake fan is in a confined space with little or no ventilation. Ever notice how everyone else has their fan sticking out a window, or it is completely outside and just tubed into the apartment? There's a reason for that. Get the installation redone.
Now for the bad news. This is going to cost you. Usually AC guys just charge you for the tubing that they put it. The tubing usually costs about 15,000 per metre. That is probably why some cheapo installed the intake fan the way they did, to save money. I recently reinstalled my AC and had the fan installed on the roof of my building. It cost me 90,000 won. Be prepared to spend a similar amount.
I can't see how anything will improve for you if you don't get them to take that monstrousity out of your veranda. |

Thanks for your input. The AC unit is in a closet in my apartment. I don't have a veranda since I'm on the 4th floor of a "Hi-rise" building....so the options may be limited. Not looking forward to spending a pile of money!
Cubanlord......I forgot to answer your question about the other unit in the closet. I have no idea why it's there as the pipe doesn't even come into my apartment....another question for the building manager. At the moment there isn't even room to put a fan in there.
Since I opened the vents, the outside of the closet door isn't as warm and the temperature reading on the AC has gone down a couple of degrees. It will be interesting to see what "they" say about it. Now I'm really dreading my first hydro bill. Thanks, again. |

get a small fan at your local E-mart and place it in there. Leave it running. THAT will make all of the difference you need.
In regards to the other A/C, I bet it is a neighbors and they had it installed there before you moved in so that THEIR closet wouldn't heat up like that. |

I would guess the same -- 1 closet containing 2 condensing units for 2 adjoining apartments. I've seen this layout before in recently built officetels. The closet has two doors, one on either side, each opening into the other person's home. What's to stop someone from climbing through the closet and burgling the adjoining unit? Not enough crawl space. Funky, huh? Not enough space for the condensing units to work properly either, apparently. And what happens if cats, dogs or vermin find their way in there and create a nuisance?
But residents don't "have it (the A/C) installed" AFAIK, they're pre-installed as part of the interior installation work before the officetels are even sold, so it's not a case of who gets there first gets the best position.
I'm not sure what I'm seeing in the first photo (what's that long white/grey strip along the right edge of the pic?) and I'm not seeing that pane of glass you suggested the OP should remove.
About having the condensing unit re-located to the exterior of the building... good luck. See if any other tenants have done that. It may not be possible. |

it looks like there is a pane of glass sealing the outside from the vents. Though, the OP said he had already opened the vents. (I guess I need to get some glasses ).
That gray strip; most likely the boiler (heater) for the apartment. |
