    404Power... Yes a blend of R600(a) + R290 + ethane + R23 + R14 + Argon (R740) should work And I think -140C @150 watts just might be achievable with the first compressor you mentioned (don't forget that the line connecting your chiller to the evap will probably account for at least 10 watts of this due to insulation losses).

    One more thing: I also have a Copeland Scroll air-conditioning comp around here! The problem is that this scroll comp has an internal bypass valve which opens @ a HD/ND ratio of 1:10! --> 1bar @ suction / above 10bar @ discharge --> bypass valve opens!
    Is this comp also useful for me? Don't think so! What's your opinion?
    I don't think so either

    Side note: I usually don't respond to PM's or emails regarding the projects that I post in the forums. I feel it's much more fair to all, to answer questions within the forum topics themselves.
