Abstract (en)
[origin: EP2051030A2] The invention relates to a method for temperature control of CO 2 as well as metering and filling of CO 2 systems by means of a system having a process unit and a filling unit, wherein CO 2 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 CO 2 is metered by the passage through the meter (4) and is filled into the CO 2 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 CO 2 is metered and filled into the CO 2 system. Formation of gas is avoided hereby, so that the amount of CO 2 may be metered correctly.
