I dont mine ETH. So, the power consumption is low. 48 GPUs eats only 4200W
The income isnt important. This is my hobby. I want to see everything well running, clean and tidy.

The AC system is the inverter one. The power consumption is 400W-2200W. It changes all the time.
Static will be problem ? or any other problem ?

My rigs are running on the same room with the AC for a few days. There is no any problem so far.
The AC doesnt blow the air to the rigs directly. The room is enough cold.
I set autofan option in HiveOS. The temparatures of the GPUs are 59c-66c.
I dont want GPUs are so cold. 59c-66c is enough for me. In this way, the AC system eats lower WATT.
The important thing is the GPUs has no dust, no overheating.

My Mitsubishi commercial AC also has the benefits of a variable speed inverter scroll compression which means:

Conventional compressors typically only run at one speed and can only cycle
between on and off – not an effective method for delivering cooling in a
server room. The P-Series is equipped with Mitsubishi Electric’s quality-made,
durable variable speed inverter scroll compressor that can adjust its speed to
provide precise cooling as needed. This means:
• a consistent, precise temperature is maintained at all times;
• increased energy efficiencies, resulting in cost savings;
• when a server room expands, the P-Series can adapt to the increasing heat
load without requiring the installation of additional equipment.

My AC cost me around 3,50 CAD per day (2% of my average daily revenue) for continuous sensible heat load of my minage room. I will soon add more GPUs and will capitalize even more on my AC daily cost even though I spent many hours to set my node validator on RocketPool for the upcoming ETH merge.

the data sheet you posted stated it is twin rotary and not scroll compression.

a non inverter will be having the same performance as an inverter at maxed out capacity.

the only good thing about an inverter is this

• when a server room expands, the P-Series can adapt to the increasing heat

because it is better in adjusting than a typical thermostat which is an on-off switch.

but i'll have a different strategy if i were you, i'll use a non inverter windows type 12,000 btu first 50% setup of the rigs, as the mining expands i'll add another 12,000 btu. the benefits are..
- non inverter AC are cheaper.
- if an AC has a problem you can run your farm at 50% (backup model)
- window type are just square boxes, 12000 btu AC is still small enough for a single person to remove and install, so if you are a one man army like me, you can DIY (change capacitor, clean, install etc.), no need to call anybody and waste time. non inverter AC are lighter than inverter AC BTW.

have a spare AC so you can continue mining while an AC is in maintenance.

have an air filter sheet that you can place over the evaporator intake, this will reduce you maintenance times for cleaning the evaporator.
