Description
As first results with customized commercial CO2 cooling unit have been promising,
we started further test runs with a changed test setup to investigate operational behavior in detail.
We inserted capillary heaters to achieve a two phase CO2 cooling environment more similar to the Belle II PXD and upgraded the control structure.
We focused on temperature stability, response to load changes, and stability with 'active subcooling'.
Results of these test runs will be reported and possible applications of such commercial chillers will be discussed.
