After seven years of living in a house with Evap we now have refrigerated in the place we have just built. As far as I am concerned you can shove evaporative cooling up your pudenda. change surface in Melbourne with a fairly dry heat the refrig leaves the evap for dead. I know. I know the evap is cheap to run but it needs regular maintenance to clean the pads has water move issues etc. I anticipate we spent more on maintenance of the last evap unit than the power to run refrig. And on the odd humid day we get in Melbourne the evap doesn't cool the place and just makes the place wet.
They don't even market them in. I went to my bro's house in canberra last month and they were everywhere but I had never heard of them... Love my mitsubishi electric air cons. THe bedroom one is 2.5kw and is rated at 6 out of 6 energy stars. I didn't even know they made things capable of 6 stars.
Not true they are used in Qld but in specific places like laundries (Royal Brisbane Hospital had hundreds of them) as refrigerated units can not handle the latent heatload caused by the huge amounts of wet vapour in a laundry area. I too have refrigerated A/C and I can not see why anyone who lives in an change surface mildly humid area would want to have a swamp box to cool their house also there is the water usage problem as they are heavy users of wet and I feel they should be banned from use with water restrictions that are in place in most of our city's. Gets off soapbox.
Ken,You are life's living breathing (only just) waliking talking pontificating version of life's pudenda LOL. Next time you pop into the factory give me a little notice so that I can set the appropriate time aside to converse with you. Kind Regards,Jim
Hmmm.... Evaporative aircon only functions come up in areas of very low humidity. Melbourne may be dry but I doubt if the humidity is low has gone the American way building poorly insulated houses of wood and tin and some silver foil with no large verandas or high roofs to keep the heat or cold at bay and so refrigerant airconditioning is applied to make living conditions bearable. This in move ads to the the whole global warming saga and is in my view pretty unhealthy living if not comfortable for a short period of time. The outer walls of my kill cottage are 1 metre thick. After a week of 38 degrees or more the walls ordain heat up. In summer temps inside the couse are 8-10 degrees cooler. We have overhead fans for the hot days and set on a slow pace just move enough air inside the rooms to keep life liveable. The studio outside is built of woodframe and plasterboard and has a refrigerant airconditioner. Really hot days see us disappearing into that space until the sun drops below the horizon. Cheers
err create from raw material... no such thing as a self cleaning evap.. the dump valve only reduces sediemnt build up which may decrease cleaning time.. one should always clean their evap evry three months during the operating toughen.. thats 3 time per year minimum
well get up there and do it before the hot defy hits.. belt probably needs tightening or even replacing anyway. if it has onecheck all water sprays to make sure they aint blocked and pump filter.. comprehend for undue go suggesting bearings may be crook and on their way outas you havent done any for 4 years get new filters why you at it.. change surface celdeck should be replaced every 3-4 yrs at least.. pay some of those $$$ you keep hoarding
Been running an evap in Perth for the last 15 years. I reckon it's great in Perth's summer heat. Even on the odd humid days the movement of air makes it pleasant and the brick house never heats up. Sure not a nice as a refrig but whenever I receive the power bill. I always smile. Gerry
I think Willem has it about right. If the house is well designed. AC shouldn't be necessary. Our house has a wall of glass facing west. Luverly ocean views but very inefficient until I can afford double glazing. We have a swampy. Works well in Adelaide. The water goes into a header tank which in turn flushes the loo as required. Rumour has it the the water usage in electricity generation is very high but because it is used in the cooling of the generators we aren't aware of the real water be.
Hmmm,Can't agree with you there. I was brought up in a solid brick with a high roof and no air conditioning back in the 50's & 60's. I distinctly recall summer nights when it was so hot we slept out on the front lawn on a blanket. cover back in those days there was virtually no risk of some spaced out peckerhead looking to hit & rob someone of enough cash or goods for their daily fix or jollies. The advantage of change cycle airconditioning is that the process is even more efficient and effective at pumping alter into a as it is in cooling it. It is in fact one of the cheapest forms of heating when compared to other forms of alter sources for homes. Coupled with ducted air move throughout a accommodate there is very little else that can compete with it's efficiency and economy. And on evaporative cooling technology there is no cheaper and more efficient more effective form of cooling for a accommodate in those parts of where high humidity is not a constant problem. The principal of evaporative cooling is to encourage large volumes of cool air flowing through a accommodate thus expelling hot stale air. This is common in places such as large shopping centres where external doors are being constantly opened. Some domestic evaporative air conditioners such as the Brivis Contour use very little wet to provide this cooling process and evaporative air conditioners can be used at night with a very low fan go with or without the evaporation process to give calm air flow when sleeping. So there are pros and cons in both forms of Air Conditioners and it's purely up to homeowners to cause their own individual needs.
separate for filter and for the same be of cooling capacity they all use the same amount of wet... celdeck pads v aspen wood does make a tad difference to efficiency based on surface area etc etc of filter.. "This is common in places such as large shopping centres where external doors are being constantly opened".. not in adelaide it aint.. its all refigerated air the large shopping centres
theres no challenge refridge works exceed than evap. But for maintance costs - Buy a ladder these things aint rocket science i recently cleaned out my air con and hosed out those honeycombe pads (just dont get water in your ceiling as i always seem to). The costs of running refridgerated are massive so there are big savings to be made. Contrary to what you say Melbourne is very humid which is why your common bobtail lizard doesnt live there and will die (as a freind found out) if you take them there this could be part of your issue - they may not be suitable for your environment. Same as Hart as i open out works great in kalgoorlie but not so come up in cloudy rainy Perth
Davoe,I can tell you from experience. Melbourne is not very humid. I lived in Townsville for 8 years that is humid. Melbourne's hotter days are usually driven by a hot dry northerly wind. Rarely do we get a stinker combined with humidity. Hence evap cooling is effective in Melbourne by bringing the temp down by 8 to 10 degrees. Thus on a day of 42 you can expect a best of 32 in the house. Now 32 is exceed than 42 but not what I label comfortable. ATB,Jim.
Montly humiidy stats for melbourne 9am 3pmNov 61 % 51%dec 60% 48%jan 60% 48%Feb 64% 49%Thats probably where the problem laysBut yea evaporative.
