借帖子问一下,各位给力的水冷出风口是单独安装在屋顶的,还是和ducked heating 共用管道走地下啊?
我也知 ...
The tubing must be seperate.
My house is 35 sq ~ 330 meter square double story (new house). The cooling vents usually can not be extended to downstairs so you rely on cooler air naturally run down stairs. This may be why they say evapoative cooling is more suitable for single story houses. In my house, evaporative cooling is more than enough to keep below 30 degrees up and down stairs. My stairs are in the middle of the house so maybe different to other house structures. I do have external blinds on north and west facing down stairs windows. Like these. http://www.allviewblinds.com.au/img/external-blinds-1.jpg
In terms of cost, I have DODO so I can track my daily electricity use.
No evapoative cooling - average use 7 Kw
On Tuesday, 24 hr non stop evapoative on high setting (80-100 % maximum isetting n day peak hour, 30% at night) 20 Kw. So about $4 per day for 24 hr non stop.
Then there is the water consumption -hard to find good information any where...
this is the best I can find. http://www.waterrating.gov.au/sy ... ir-conditioners.pdf
Assume it uses 120 Litre per hour - 2880 Litre per day at $2.6 per 1000 Litre
So total running cost is about $10 per day for both electricity and water if running for 24 hours.
