Aceasta unitate phase change a fost planificata a fi construita la finele lui 2014 , insa abandonata din motive personale a persoanei ce a solicitat aceasta constructie.

Este vorba de cineva foarte cunoscut si popular de pe acest forum precum si mult timp in topuri pe hwbot cu raciri conventionale , personal imi face o deosebita onoare ca in viitoarele lui submisii( sigur multe WR-uri) este folosit un cooler proiectat , calculat si executat de mine ...

Lasand vorbaria ( trebuie sa recunosc ca nu este punctul meu forte ) o sa explic despre ce este vorba si ce componente vor fi introduse in acest build.

Practic unitatea de fata este un fost proiect care nu-i mai gasesc intrebuintare, evident va suporta modificariile de rigoare , vor fi folosite doar :baseplate-ul , condensorul si evident compresorul .
discharge , liquid si suction line precum si schimbatoruld e caldura ( evaporatorul -HX) vor fi intoduse corespunzator targetului initial calculat.

Compresorul este capabil de ~ 4700W cooling power la o temperatura de 7.2*C ( evaporating TEMP)testele sunt facute de catre producatorul SCI ( siam compresor industry)

application -hight temp
ambient temp :35*C
return gas temp: 35*C
condensing temp : 54,4*C
subcooling temp : 46.1*C
evaporating temp : 7,2*C

teoretic pentru o sarcina de ~ 2 KW ( 4 way cross fire /SLI cu gpu-uri actuale) ar trebui sa avem HX-ul la temperaturi negative de aprox -25*C , pentru 1kw ( single gpu ( ex : hawai , maxwell)voltat astronomic) -35*C , pentru sarcini inferioare -40 -45*C HX temp!!

specificatii:

rotary vertical compressor SCI RE277VHSMT

capacity BTU/h -16036
cilinder displacement 27,7cm/rev
cooling power 4700W
input power 1520W
motor typ PSC
40uF run capacitor
internal overload protector
oil typ POE MEL56
weight 15,1kg

condensor ECO 3,3kw , AXIAL PAPST motor 300mm fan Blade

HX: HARLE B3-12A-30 brazed plate heat exchanger -30 plate

TEV( thermostatic expansion valve) Danfoss TES2 ( external equalizer) with MOP
Best Air Hoses
liquid line:
- 6mm cooper pipe
- 1x schrader valve
- ALCO 50g filter dryer
- ALCO Sight glass



discharge line:
-8mm cooper pipe
- Hight pressure cut off saefty device Ranco DWK 77-10
- hight pressure oil charge manifold/manometer gauge -FISCHER 80mm Klass 1

suction line:
-12mm cooper pipe
-1x schrader valve
-1x PT100 sensor ( monitoring HX temp)
-suction accumulator -included by compressor arhitecture!

others:
- digital temperature panel meters TPM-900
- 2x plug power for bench rig
- 1x 25A Wipp power switch
- 4m power cord 3G1,5
- base plate 53,5cm x 48,5cm multiplex
- 4 x 30mm gumy legs
-refrigerant R507


water loop va fi configurat de catre utilizator...
