You say “Theoretically Sydney should be a suitable climate as well, however they have not as yet been accepted there. Part of the reason, I believe is due to lack of knowledge of how to get the best out of an evaporative cooler.”
I have a new flat roof 45sqm room, that I’ve gone to a lot of trouble to insulate *all* around (R6 in the ceiling etc), double glazed, low-e glass timber framed windows blah blah etc.
I understand that Sydney is generally more humid than Adelaide etc but I’m also aware of chewing energy.
Can you give me “knowledge of how to get the best out of an evaporative cooler”?
I am pleased to see you have gone all out to minimise energy waste in your house. Hopefully the rest of Australia will eventually follow your leed with double glazing etc.
Re evaporative cooling, the biggest issue is one of expectations. With evaporative cooling in Sydney, there will be at least 150 hours per year where the cooler only provides relief, rather than comfort. There will also be several days per year where there is a strong possibility of condensation occuring on concrete floors and sometimes masonry walls. During these times it is necessary to switch the pump off and just use the cooler as a ventilator. I originally wrote those words about 8 years ago, and I think that peoples expectations have increased further since then, so now I don’t think evaporative cooling would be accepted in the area except where there was no alternative, (eg large factories, people on remote area solar power or similar). One possibility in Sydney would be to use an evaporative cooler for those times when it is able to provide comfort and to switch over to refrigerative when it is too humid.
