A decision has finally been made! After many conversations with my HVAC engineer and HT we decided to go for the following: The control room will have a 3.5kw Fujitsu ducted split system and the live room will have a 4.3kw system. The models for those interested are:
ARYG12LLTB/AOYG12LALL and ARYG14LLTB/AOYG14LALL The decision was based on many factors including consideration for Static pressure, noise levels and size of the air handling units.

A break in the cold weather meant I could make a concrete pad for the condensers and we had the units delivered this week.

I will be mounting the units, running the pipework and cable leaving the testing, final connections and commissioning to Valdas the engineer. As the refridgerant is hazardous to the environment it is important that none escapes and HVAC engineers have the necessary equipment and expertise to ensure this does not happen. It isn't worth the risk to DIY and in addition the advice and feedback from Valdas has been invaluable and it means I get a valid warranty.

I have to increase the number of attenuators and size of duct to ensure there is satisfactory airflow across the inverter coil to prevent any problems! This will be challenging because the baffled type attenuators are very bulky. So I will be making a different type for the live room which will be smaller in cross section as they won't have baffles but will be 2.1m long! The design comes from RA the book, thanks Roger!
Another order of materials required.

I have been doing a few things like boxing in ducting running cables and more layers of plasterboard etc. I'll have a sweep up and post some fresh images a little later.

Looks great, Tony. Is the (grey?) external cladding the vinyl-coated type or plain wood?

Hi,
The external cladding is actually a cement fibre board. It has a wood grain effect moulded to the face. I had to have a cladding that was fireproof as it is 2m away from the boundary. (That was UK building regs). It was a product from Marley. It is pretty good as it doesn't rot. It just takes an acrylic exterior paint for decoration.
Cheers,

Air conditioning compressors in place, isolators wired in and refrigerant lines run between units.
Image
Fan coils in place. I suspended these from brackets attached to the outer shell trusses with neoprene washers to limit any vibration, although these fan coils are rated as quiet anyway.
Image
Meanwhile I am getting on with building the final break out attenuators for the live room which are Rockwool lined boxes 2.1m long with offset inlet and outlet. They will be close coupled to the ceiling and covered with plasterboard all round to the same mass as the ceiling and lined with 50mm Rockwool.
Image
Finally I made a start on boxes for the fresh air fans to cut down on noise. Originally I was going to mount the fans externally but having made a prototype box I am happy I can silence them, so they will go inside. Similarly they will be suspended from the shell and I will make a post in future on the detail.
Cheers,
T

Some updates from the past few weeks.

Refrigerant lines and fan coils in place through the loft space.

That's the air-conditioning complete.

FreshAir Fans
I made a box from MDF
Image
I placed the fan in-between the inlet and outlet and used a fabric tape to prevent a hard connection and then lined the box with Rockwool.
Image
The boxes are suspended using neoprene washers so there is no chance of vibration.
Image
The connections to the attenuators are made with acoustic flex duct.
Image

The fans were very quiet although I could hear air movement noise at the fan outlet connection so I covered the duct with more rock wool which has done the trick.

This thread should be required reading for everyone who comes on the forum asking how to soundproof their spare room / garage etc. :)

Thanks, not sure if it is friendly advice or a stark warning!
I wanted to put four spot lights in the ceiling. I made 4 boxes from 18mm MDF
Image
I then covered them in MDF and plasterboard layers to match the mass of the ceiling. They end up quite big and heavy.
Image
Excuse the pipes, I'll trim them flush with the ceiling when the final layer goes on.

Just me being impressed at the work you're doing and thinking of the occasional posters looking for 'cheap soundproofing'. :)

Take my advice, I'm not using it.

Are you planning to fit diffusers on the supply air ducts? They can make a huge difference to the way the air mixes. You don't want cold air 'dumping' or warm air sticking to the ceiling (depending on the mode of operation of the FCU) rather than mixing in with the room air.

Hi,

The inlets and outlets in the tracking room have been strategically placed so they will be behind the acoustic panels of RW3 mounted to the ceiling. This will help reduce/mask any airflow noise at the outlet and act as a sort of diffuser to mix the air a little on the way in. There wlll be no grilles as I didn’t want any airflow noise.

In the Control room I plan to mount small panels under the outlets made of wrapped RW3 to achieve the same.

I am looking forward to getting to that stage. Have just been told my order of 50mm RW3 won’t be available until 27th March due to a shortage! And MDF has gone up in price again! Nearly 25% increase since September! Hey ho that’s one less mic.
Cheers, T

I'm just afraid there won't be any mixing going on, as all the air behind the diffuser will be at a higher pressure than the room air, so all the air behind the panel will be supply air and won't mix until it reaches the edges. This air will be travelling horizontally, so in winter, buoyant hot air will be encouraged to stick to the ceiling, where it will either get extracted to outside or recirculated through the FCU, which if operating on a return air sensor (as a lot do), will think the space is warmer than it is, so the space stays cooler than the set temperature.

Expanding the duct area at the grill by a conversion piece to a larger round or square section and a grille would reduce the air velocity over the grill (although it has to be within limits to work) and you shouldn't get any extra noise from having a grille.

I hope you don't have any problems and my fears are unfounded, but if you do have problems controlling the temperature in the space, you might have to move some of your clouds away from the supply ducts and retrofit some grilles.

fantastic studio you are building!
I built my own ten years ago, also starting from the foundation.
now happy =)

Cheers, Just had the structural stuff signed off by the BCO so can get on with it. It was a bit of a grey area in terms of whether the local authority would need to be consulted because the studio sits inside the existing structure, which isn't yet itself signed off. As I have a good relationship with the the building control team I ran it by them and had the pre-final inspection and everything was to their satisfaction including fire escape etc.

So hopefully will have a few updates soon.

In terms of the air conditioning it is always a compromise using the same ducts for heating and cooling. If I ever have to make or try to squeeze in another attenuator it will be way too soon! I am hoping that once the room is at the required temperature I will only be concerned with cooling. So when heating the room from cold, I'll blast it (takes about 5 mins to heat up the shell) and then just let the insulation and heat load do it's thing.

The only minor change I may make is to create a room side plenum so I can put filters in because it will be a ball ache to get into the loft space to change them. Also I had to tape up all the fan coil plenums as they were in no way air tight.

I should have listened to the designer who said mini-split!

Cheers,
T
