Well it's 44+ degress outside and our house has ducted air conditioning which is spilit into 2 zones, 1 for bedrooms and 1 for living areas. Our 2 small children are having their afternoon sleeps and we have put the air-con on for them which means we can't have it on in the main living areas. The only choice is to sit in the bedroom until they wake up - not much chance of getting any thing done then!!

Out of curiosity why can you not have it on in both zones. You should keep the bedroom doors open if you do so that the air recirculates properly into the intake. ??

Ducted aircon IMHO is crap. I've never known anyone who loves it or who thinks it works

Now lets see loads tell me differently

Number one coming right up!!! We have ducted reverse cycle in 6 zones. Each bedroom is separate and the formal area and family area are each zoned. If we have all zones on at once it isn't great but better than not having it. We normally put it on in max 4 zones and it is absolutely fine and gets the temp down from 29 (which is our cut off for putting it on) down to 24 which is our comfortable temperature.

Split system reverse cycle units all the way for us.

If the system has been properly designed and installed, then the air conditioning for the two zones should be entirely separate and the cool air flow in individual rooms should not depend on leaving doors open.

A well designed system will have either a 'return vent' in each room or air grills in the door of each room to enable them to share a common hot air return.

Allowing air from one zone to enter another zone may well 'overload' the cooling capacity of the first zone and could be the cause of your problem.

Please feel free to PM me for further information.

P.S. When was the last time you cleaned the air filters ? .......please don't say "where are the filters ?"




The air

Hino

Stand by to be told differently......

Nothing at all wrong with zone control on A.C. systems. They are both energy saving and cost efficient.... when properly designed, installed and maintained.

sonlymewalter

...told ya

Thing I've noticed is you have to use various zones for it to be effective, if you move any internal walls and change the dynamics of the original set up it often becomes innefective, and if any redirection occurs you can get water leakage

I respect your views mate but for me I give ducted air a big fat tumbs down

Give me reverse air systems every time

sonlymewalter

Now...let me guess. Are you a ducted aircon specialist by any chance

Wherever there is ducted aircon in offices you see cellotape where folks have tried to redirect the air by sticking cardboard over the vents. It's bloody useless IMHO

Sorry mate, been burned with it too many times. I wouldn't have it if you gave it me for free. Much prefer split systems

Hino

Happy to amuse you

"Thing I've noticed is you have to use various zones for it to be effective"


That's why it's known as zone control

"if you move any internal walls and change the dynamics of the original set up it often becomes ineffective"


So you're saying that if you increase the size of the cooled area without increasing the cooling capacity, then the system will become inefficient ?

" if any redirection occurs you can get water leakage"

Not as long as you don't mess with the original installation and you keep your drains clean.

sonlymewalter

Yeh, only thing is the zones you get are never the right ones

I'm saying whenever you change the dynamics of the original internal layout, you lose any efficiencies. Quoting the aircon "specialists" they tell me "the balance is no longer the same"

Exactly - if you change the layout of your internal walls the system is even less effective than it was previously

Sorry mate I know you love it, wish I could say the same. Ce la vie

You didn't answer if you were a ducted aircon specialist?

We have only been renting the house for 6 weeks and it is a brand new built, all the rooms have the ceiling vents which can be screwed up or down to allow in more air. It is very effective in each zone when it is on, it can't be faulted on that score. It has a control panel for temp, fan speed etc, but is also controlled by a switch (like a light switch) for day-time and night-time I assume to make it cost effective, it is just really annoying when the kids need their afternoon naps -this is day 4 of temps in the 40's aswell!

Hino

Hi H.J.,

Now I'm really confused

If the system is working well, then why your original post about not having A/C ?

iamthecreaturefromuranus

Two Daikin R407C Super Inverters... It could be 45c outside but if I put them both on maximum cooling you would need Ugg boots, fur hat and woolly gloves on.

Howard Jenings

The complaint was not about it not working, it was about it being zoned and not allowing the bedrooms and the main living areas to be cooled at the same time, meaning when my kids have their afternoon nap the rest of the house is boiling hot whilst the air-con is on in their bedrooms
