Phase Change Assembly Line Produces V2000B Single Stage
11.19.07 - 03:24pm
This unit is a story of many delays as it was my first V2000 build. Now that I’m done with it and satisfied I must say I’m rather pleased with how it turned out and will most likely be making myself one but I don’t know if I’ll build another V2000 for a customer as it took a lot of custom fabbing and work. Quite the fun build but with it spanning nearly 3 months(roughly 5 times my average build length..) was mind-racking. Glad it’s done, it was a beautiful build to create but I’ll stick with my bread and butter single-stages unless someone really wants another.
Stats
This is just another one of my standard NF11FX builds but it’s crammed into a Lian Li V2000B case. Must admit it was rather difficult working with the limited confines of the case, especially considering how I designed the unit to be completely removable from the case. This particular unit handles 300w like a breeze, the Cryostar evaproator really seems to help with the load-handling characteristics.
- Compressor: Danfoss NF11FX
- Condenser: Chilly1 Little Blue
- Suction: 24″ of flexible stainless steel
- Evaporator: Cryostar
- Controller: Freeze Pack with MeanWell 12v PSU
- Case: Lian Li V2000B with drilled out faceplate
- Charge: R507
Performance
The Cryostar is a rather effective evaporator and required a slightly different tune in the end compared to my typical spiral evaporators. I could achieve the same load handling characteristics with proper superheat values but with slightly lighter charges with lower pressures. The final charge to hold 275w ended up being 7psi suction and 260psi discharge with an evaporator face temperature of -18C, loadtester core of -10C, and an evaporator backside temperature of -33C(as read by the controller). Total power drawn from the wall at 275w load was 411w and includes the entire unit and two 80mm exhaust fans. Floodback occurs at roughly 90w which wasn’t too bad and was a little lower than my spiral builds. Compressor and exhaust fan noise was quiet but once again that 110v condenser fan is a jet engine, may need to start replacing that fan with a nice Panaflo.

That’s it, the queue is empty and now I have a chance to finish up a prototype of mine. Have my Thanksgiving break coming up, looking forward to having no deadlines to meet and getting to break in some Ruby on Rails books along with a good fiction novel or two.
