Ok, i've been saving up, possibly for a SS. For me, is it worth it? Remember, i'm a senior in hs, so i still have 5 or so years of not paying the electric bill.
Also, sdumper said he tunes his for -40*C @ 300w. I have always wondered something about this. If i put a lesser load on it, say 150w, will the temp be lower (ex. -70*C), or does it only go to -40*C, but it can stay there up to 300w?
I'm just thinking, because my dice place is far away, and with phase i could be up and benching immediately. I would think this would be nice for me especially now during the school year, because i have alot less time to bench.
Basically you will only see -40c.
The real problem is that if a system is tuned for 300watts and you only load at 100watts , you my have refrigerant flood-back to the compressor(Liquid Slugging).
That is Very, Very bad, and can destroy a compressor quickly, as liquids are Non Condensible.
I know Sdumper is a good builder,and uses suction accumulators which help against floodback.
But if you dont tell him your intended usage he can't compensate for a lower thermal load.
If he knows before hand its a simple fix.
All that's necessary is to lengthen the cap-tube(or go with a smaller I.D.) for a lower load, and this in turn can yield lower temperatures.
Capacity and temperature are interrelated, lower temps yield a lower capacity/ higher temps yield a higher capacity (heat-load)
If you have any more refrigeration questions feel free to P.M me
