Wip : Ss
 
Hi folks,
After my single stage practise unit i thought it was time to make something worthy to use :D With some luck i found a free and useable coolgroup. It had some nice components in it and all they needed was some refurb loving :D

Here are some pics to start with

The victim


Trading old for new

Made proces, paintjob


The compressor is a pretty strong Uniti hermetique CAE9460T.
I wil update this now and then while more has been done

*edit*
A bit more work has been done :D

Overall look without fanhouse


New vibrationpads underneath the compressor, the old ones were really grannystyle


Any comments on the de-superheater coil?
The suction lenght?
I'm going to take 2.4M cappilair

hehe my prototype reached -32c, the one with the 1/8HP compressor and supersmall condensor.

This unit wil be complicated, i have a R22-502 compressor, so i'm forced to put an alternative gas on it wich is R417A or if possible to change oil R402a.
And i have no idea how that will work out, my best gas laying around is R410A. But i can't use that one cause it would kill the oil and compressor .

I'm hoping to reach at least -50c idle :D

Yesterday first test of the system .

Learned allot :D

it seems that evap design is really important , while gassing the system and starting it, temps were dropping very very fast to -40, once the system was filled temps dropped back to a loazy -25c within secs...i was scratching my head, how could this be possible???

-->evap
I made a custom test evap at work , but it has no canals and the capilair lays next to the suction line, in other words , it goes in and gets sucked away before it even makes change to evaporate lol.

Anyhow, a decent evap wil be made so we can test again.

System was filled with R417A
