(54) A method for temperature control of CO2 as well as metering and filling of CO2 systems


(57) The invention relates to a method for temperature control of CO2 as well as metering and filling of CO2 systems by means of a system having a process unit and a filling unit, wherein CO2 is continuously pumped through a hose (8) from the process unit (1) at a temperature below 31.1 °C and comprising a container (2), a pump (3) and a meter (4), through a circulation valve (6) in the filling unit (5), which comprises a circulation valve (6) and a filling valve (7), and back to the process unit again for cooling, following which the circulation valve (6) is closed and the filling valve (7) is opened, whereby CO2 is metered by the passage through the meter (4) and is filled into the CO2 system through the filling valve (7).
An alternative method, wherein the process unit (1) additionally comprises a circulation valve (6) and a parallel valve (9), wherein the circulation valve (6) is closed, the parallel valve (9) and the filling valve (7) are opened, and CO2 is metered and filled into the CO2 system.
Formation of gas is avoided hereby, so that the amount of CO2 may be metered correctly.
