C02 extractor design

12L/minute is a great flow rate. You are going to need a multi ton chiller and several hundred thousand BTU's of heat to deal with the thermal load and.

I came up with 30k btu's cooling and 30k for heat. 12L/min flow.

I figured 120F to 20F so a 100 degree drop. Online calculator says 150k btus for water but c02 has a specific heat of around .2 at those temps. I could be way wrong though.

I will be building the chillers. One direct with a plate exchanger and one recirc for keeping the c02 accumulator cool.

Looking like 120+ amps to run all this.
