ᐅ Heat exchanger for recording studio – Need advice

Hello everyone!

I am about to build my own recording studio. It’s not for commercial use, just for fun, so I can’t afford professional companies to design and build it for me... However, I have a friend who knows a bit about ventilation systems and will help me with the construction.

I am considering installing a cross-flow heat exchanger with silencers and a heating coil that will warm the air a few degrees after heat recovery.

A few questions:

- Rooms 1 and 2 should be acoustically as independent as possible, meaning minimal sound transmission. The ventilation openings in the wall are disadvantageous from a building acoustics point of view, but cannot be avoided. Therefore, I’m thinking about installing the ventilation unit in a separate room (e.g., 1m x 1m (3.3 ft x 3.3 ft)). This way, the spots in the wall where pipes go through are separately built-in. Does this make sense? Should I also encase the entire supply air duct (green, on the left) in this case?

- Where should the supply and exhaust air openings be placed in Room 1 for best performance?

- Air exchange rate: the room has 100 cubic meters (3,530 cubic feet) of volume. For office use, a 6 times air exchange rate is specified. Since I will mostly be alone in the room, would a lower rate suffice? Also, 20-30% of the volume will be occupied by absorbers, meaning porous material wrapped in fabric that allows little to no air circulation. Can I subtract that from the total volume? Would a central heat exchanger unit with 300 cubic meters per hour (177 cubic feet per minute) then be sufficient?

- Can you recommend a particular heat exchanger? It must be especially quiet!

- Such devices always specify a range of cubic meters per hour. Which value should I use? Again, quiet operation is the top priority here.

Thanks so much already, your help means a lot!

That’s a relief for me… also financially 🙂

What kind of device would be suitable for that?
I also read that I should run pipes with the largest possible cross-section into a sound studio, because the resulting lower flow velocity reduces noise…

That makes it much easier... especially financially 🙂

Do you have any tips for a device that is placed outdoors? A decentralized system is possible, great idea!
I only find living room units up to 150 cubic meters (5300 cubic feet) and then industrial units starting at 300 cubic meters (10600 cubic feet) for several thousand dollars...
