Air Conditioning for the garage
Minicooper - 11/6/07 at 09:11 AM

Due to global warning and being fat and old, I'm looking to air condition the garage, I'm not kidding, I like mucking about in the garage but with the heat/welding/grinding I'm overheating.

Due to the dust, grinding and welding fumes I would need a proper unit I think, I have a portable unit in the house and it's great but I think it would clog up in no time if I tried to use it in the garage

Cheers
David

What you want is a car radiator and fan, a header tank and a bucket of cold water. The fan will blow air at roughly the temperature of the water, 10° or 15° on a warm day.

10 litres of water has the same specific heat as 42 m3 of air, so 10° water and 30° air will settle out at a nice 20° each.

After that, the air in your garage will heat up again, but at half the rate it would without the water. The advantage of this system is that the water is in a sealed container and so doesn't evaporate, humidifying the air.

Are you not worried about the amount of energy/cost that air con in the house and garage will incur? Surely Hampshire isn't that hot!?

The air conditioning isn't run fulltime, for instance the one in the house I put on for a half an hour just before bed so I can sleep well.
When your welding and grinding with a boilersuit on, the heat for me is so uncomfortable, I would do the same thing in the garage switch it on for half an hour before I went in to work and than maybe switch it on as a top up a couple of times a day

I'm from the North East originally and I find the heat down here too much, remember us northerners wouldn't think anything off walking to the pub with just a teashirt whilst it's snowing I have done many times, and no I'm not bothered about running costs within reason

I have a big fan on a stand, which helps a great deal. Doesn't cool the air down (probably heats it up a fraction of a degree!) but it does keep it moving, which is a big help.

As a southerner who has moved up north(ish) I can see why a northerner moving south would find it a bit hot!

When you're grinding etc the evaporator (indoor unit) will still clog up.

On the wall mounts the filters aren't very fine and the sh*t will still find it's way to the coil. It'll eventually ice up before going into defrost.

Evesham is not up north. The North starts between Yorkshire and Derbyshire and goes through the middle of Cheshire. Even if you draw a line from the wash to the seven, evesham is in the South.

Thanks everyone,
I will start with a stand mounted fan, as a locost option and see how that goes

I live in Derbyshire and am in the North East Midlands. If I just leave the door open it cools down quick enough with the airbrick through draught.

If you look in places like B&Q you will find that they've got some huge floor-standing fans at not too stupid prices.

Some of them could generate a fair old tornado, I reckon!

I always try to keep as quiet as possible, so rarely have the door or windows open, I should at least open them inbetween any grinding or welding that would help
