Qv = (P / (h_gaz - h_bub)) * Ug (*3.6 to get m³/h)Originally Posted by godmod
I did not calculate it myself, but I trust the calculation:
4th stage 315 W at -160°C
compressor size 20 ccm / 3,48 m³/h
Max. motor power ~ 585 W
Max condensor power ~ 900 W
COP ~ 0,54
sorry, I don't know more e.g. superheat or something...
In few weeks we will see how it works out
For -160°C captube end, -145°C out, 20°C suction temperatue you get
Qv = (315 / (705-165))*1.32*3.6 = 2.8 m³/h
Which is in fact achievable with his last compressor I think
