DA62 First Ever RAAC Retrofit
Due to operational requirements, very recently, I retrofitted the Diamond RAAC air conditioning unit into my DA62 which was carried out by DAI Weiner Neustadt, Austria.
A truly fabulous neat job which was on time and I am extremely happy with the result.
Also took the opportunity to retrofit the Garmin satcom system.
Great work!!

Re: DA62 First Ever RAAC Retrofit
Does it still only provide a single AC vent for the 2nd row of 3 seats?

Re: DA62 First Ever RAAC Retrofit
“How many vents are provided for each seating row?” is I think what UTMark was asking.

Re: DA62 First Ever RAAC Retrofit
Is the airconditioning worth the money? If read some mixed reviews.

Re: DA62 First Ever RAAC Retrofit
The RACC is underpowered, but does help keep cabin temps bearable until you get to altitude. Combined with Jet Shades, it's *almost* adequate.
In the DA62, the weight of the unit installed in the aft fuselage also helps keep your loaded CG within the forward limit, particularly when you have only two people on board. I.e., really expensive ballast.

Re: DA62 First Ever RAAC Retrofit
It might cool better in US western states with low humidity, but here in eastern mid-Atlantic states (e.g., VA and MD) it doesn't seem to do much more than attempt to de-humidify moist, humid summer air. (It even drips out the air vents.)photoSteveZ wrote: ↑Wed May 04, 2022 8:11 pm The RACC is underpowered, but does help keep cabin temps bearable until you get to altitude.

Re: DA62 First Ever RAAC Retrofit
That’s the one thing about the DA62 that I’m not super excited about here in very humid Houston… but it’s better than nothing for sure.

Re: DA62 First Ever RAAC Retrofit
I think that the misconception of how air conditioning works in general is amplified when applying it to an aircraft with massive canopy plexiglass exposure, and heat soaking.
At best, a residential air conditioner will cool about 3 degrees F per hour in a well shaded environment.
An aircraft with a lot of plexiglass exposed to the sun heats up tremendously when sitting static, so one might expect such an aircraft with a terrific air conditioner to take roughly 7 hours to cool a heat soaked cabin from 95 degrees to a comfortable 74 degrees. Not realistic, yes, and most (including the DA62's RACC) beat that metric by a lot.
I crank the engines and air conditioner within less than 10 minutes of pulling my beast out of the hangar, and have no complaint whatsoever about its ability to cool while taxiing with the doors closed. On the rare occasion I fly low due to winds, the system is more than adequate to keep the cabin comfortable for the entire flight.
My guess is that most complaints about cooling effectiveness come from folks who heat soak their aircraft by parking them with sun exposure and expect miracles from a non-miracle providing system.
