I thought DAIKEN were good but then found out that they dont rate that well in the energey efficiency department. By they way, I am building a two storey house and am thinking of having two separate units, one for the ground floor and the other one for the first floor. What does everyone think of this? Is it a good idea? Re: Choosing the right air conditioning 2Apr 10, 2007 8:04 pm We decided to go for the Brivis refrigerated add-on for our new house.
(I can hear the environmentalists screaming already) I have had no cooling, evaporative cooling and a split system and the split/refrigerated floats my boat.... Sure they cost more to run, but to have a cool house on a hot day is worth every cent in my opinion. Matt airconditioning 4Apr 11, 2007 5:28 pm From few offers I was recommended DAIKIN.
The person that recomended it was an engineer who runs the installation of an industrial systems mostly. I have a double, 386m2 house and we bought single phase ducted daikin super inverter. My expectation were: efficiency and noise. Why single phase? It is already as efficient as 3 phase but the electric cable costs less. This guy told me that none of the house aircons is able to operate more than 220m2 and that's why you zone your house. After 5 months I can say it is quiet and effective. By zoning I am reducing the power usage. I have it installed on both floors. As an extra for a very hot day with a family dinner for 10 I made a provision for future split system in the rumpus downstairs. I can see a lot of builders are installing ducted upstairs and split downstairs. I personally don't like the cold air blowing on me so I prefered to invest in ducted. the electric wiring is in case we will have 8 kids and this aircon will not handle that cheers kate Re: Choosing the right air conditioning 5Apr 11, 2007 7:00 pm Quote: I can hear the environmentalists screaming already Yes - and the next generation who will be left with the mess we've created. We need to start building passive solar homes that don't rely on air-conditioning. We really can't afford it any more. Re: Choosing the right air conditioning 6Apr 11, 2007 8:05 pm I will add these greenhouse gasses with the ones that come out of my wifes toorak tractor and my "Petrol Drinking V8"
I don't apologise for my choices. My kids can apologise for me if they feel the need in 50 years time. Until then ...... Matt Re: Choosing the right air conditioning 8Apr 11, 2007 9:00 pm Oh YSSIM,
Pokin' the bear is fun!! However i digress. The heating unit is the Brivis ME35i and the cooling unit is CDU18a-9. I have no idea about the efficiency of these units. I needed to have these units to meet the dimensions of the house for cooling and heating. Matt Re: Choosing the right air conditioning 10Apr 11, 2007 9:35 pm We are also zoning.
I am putting in the network controller downstairs and the slave unit upstairs. Zone 1 is downstairs and obviously Zone 2 will be upstairs. Based on the design of the house I figure most of the time I will heat the bottom of the house and let it rise and cool the top of the house and let it fall. I have the zoning as a backup for the really hot days and really cold days. Matt Re: Choosing the right air conditioning 11Apr 11, 2007 10:10 pm An aircon installer/repairer I asked was very definite in his opinion when I asked about brands: Mitsubishi Skip the aircon 12Apr 11, 2007 10:14 pm At a time when we all need to be cutting back on our energy use, it's very easy to build your house so that you don't need air conditioning! How? Check out http://www.greenhouse.gov.au/yourhome/t ... /index.htm for heaps of information on passive design (ways of cooling your house that don't need engines). You'll also save a packet in the long run. Re: Choosing the right air conditioning 13Apr 12, 2007 6:19 am Ah yeah, nice ideas there but even they're not suggesting that in very hot or cold climates you don't need any mechanical assiatnce. My guess is that you live in a very temperate zone, not far north Queensland, NT or Tasmania Re: Choosing the right air conditioning 14Apr 12, 2007 8:31 am Quote: But I don't think it's something we should discuss here. Why not? Oh - hang on. I'm starting to see why we're in this mess. You quickly dismiss suggestions like Elizabeth's. Call it 'pokin' the bear'. Make it entertainment. Perhaps it's denial? We live in interesting times. Re: Choosing the right air conditioning 16Apr 12, 2007 9:00 am I see the good professor was talking to the Australasian Institute of Mining and Metallurgy. I just watched a DVD called 'Thank you for smoking'. In the movie the tobacco industry had a scientist that could prove anything. It was a good satire on lobbying and how a few will try to hang on to their fortunes and power, no matter what damage they do.
I also notice that the professor Quote: conceded the politics of greenhouse gas emissions meant that attention was being given to energy efficiency, which he supported. And that link to enery efficient home design - it covers all Australia - here's remote Queensland. http://www.greenhouse.gov.au/yourhome/t ... /fs74a.htm Re: Choosing the right air conditioning 17Apr 12, 2007 9:10 am Oops.
