That is the experience I've had with the UPS we ran at the computer club. More than once the UPS was to blame for downtime. (I suppose that a failing cooling system with fluctuating temperatures was not good for the batteries... but still)

Yeah, I took a hole in the door and screwed a grille on it which that helped a little, but it seems more drastic measures are required. Plan B is to drill a hole in the panels above the door and install another vent, with the hope that convection could cause some kind of air movement. There's a tiny vent connected to the building air ducts near the ceiling, but it doesn't seem to do anything at all. (Plan A rested on the presumption that given a "cold" air intake, air pressure would not be reduced by any movement out through the vent and causing the flow to stop.) If B doesn't work, plan C is to add a fan to suck the air back out into the apartment. D involves a heavy-duty air movement device.

Fortunately the alpha seems to be running OK now, and that gives me a little time to think up a solution.

I lived in a house built in the twenties - lath and plaster, Spanish tile roof, built-in ironing board, all that stuff. The pantry had a vegetable cooler that worked great : it was like a very tall closet where the shelves were parallel wooden slats, maybe 50-50 wood and air space. At the very bottom there was a big vent to the outdoors and same at the top. Things like apples and potatoes that a refrigerator is too cold for kept much longer in this thing. And they tasted better, too - didn't get soggy. My grandmother had a name for it but that's long lost to history. She had a Murphy bed, too, but I remember the name for that one.

Don't know if it would work for your HP but it was great for fruits and vegetables.

Sounds like the principle I'm trying to employ; I doubt my electronics would enjoy the humidity of the big blue (white today) room though. :-)

I'm thinking about buying one of those portable room air conditioners, with 5 computers on in the computer room the whole house air conditioner just can't handle the watts. I don't know what the story is in Jakobstad, do you ever need an air conditioner there? All my ancsestors came from above the arctic circle in Norway and they all assured me that no one ever uses air condtioning there... 8-)

Back before they air conditioned the Hubert H. Humphrey Metrodome it used to get brutally hot during the height of summer, and the beer vendors would be yelling "beer, get your beer here, air conditioning in a cup!" :twisted:

My server room has an LG portable A/C. It vents under one of the turbine vents on the roof so I didn't have to run it out the window. It pulls about 1.2kW when active and is good for 11,000 BTU, and can keep the room under 80 F even in the summer. In the winter, with Energy Save on, it barely turns on the fan now and then to blow over the condenser coils.

I keep the door closed when the central heat or A/C are on, and I've blocked the vent in that room, so it's basically on its own environmental circuit. The G4 server has a USB thermometer to log the current temperature so I can monitor it remotely.

It used to be pretty rare, but the last couple of years I have started to notice the boxes on the sides of people's houses, but it might be what is known as a "heat pump"? I don't know anything about such things...

The temperature around here typically ranges from +25 to -25 C, occasionally going past 30 at either end. I actually have a portable AC unit for my apartment (they wouldn't let me drill a hole in the wall to install a proper one even as I own the apartment) because it's south-facing (receiving sunlight all day) and this concrete building seems to retain the heat. It's loud and not very powerful, but just the dehumidifying effect is nice in summer. Why do people think that a south-facing apartment is a good selling argument?

No, the biggest problem is that my closet is tiny, I just need to get the hot air out. Alternatively, I could move to a bigger apartment so the machines can have a room of their own, but I kind of like not being in debt :-)

Current temperature: 0C with prospects of going to -2 tonight. Unusually warm for January.

I was all set to buy one but then made the mistake of reading the user reviews of the various portable room air conditioners that they sell at Home Despot which put the stop to that effort in short order. But if you like yours Classic I'm sure it will be more than good enough for me, what version is it?

Duck, heat pump do you mean swamp cooler? Those are awesome in arid environments but don't work for crap in humidity.

Current temp here is -4 degrees C on its way down to -11 later tonight, better take the dog for her walk before it gets too cold.

No, I think it merely indicates that it can do both heating and cooling. In any event, I don't know so best not guess :-)

I think those reviews are based on unreasonable expectations. For the same power usage, a portable A/C will almost always be less efficient than a window-mounted unit, let alone a central system. If you're trying to use a portable A/C to cool a large uncontained space, it will use a lot of power and do a relatively lousy job. Plus, people don't do smart things like wrap the exhaust ducting, or they try tricks like lengthening the hose beyond the rated capacity (I, uh, may or may not have done this and may or may not have found out this was a bad idea), or they expect that a portable unit with a separate intake hose will work without it (they won't, because most portable A/Cs cause negative pressure in the room they operate).

After all that I didn't post the model. It's an LG LP1111WXR. The related LG LP1311BXR is mechanically identical.
