Description
Two phase CO2 cooling is used in several HEP experiments. One
application is for cooling the vertex detector of Belle II, using a 3 kW
chiller unit (IBBelle).
Recently commercial CO2 chiller with this cooling power became
available, aimed to be used in supermarkets. These units are compact and
available for a fraction of the costs (purchase and service) for
in-house assembled units like IBBelle.
Operating a single circuit these units are directly connected to load
without intermediate CO2 circuit.
We purchased such a unit, customized it, operated and tested it in an
environment similar to the Belle II VXD.
Results of these first tests will be reported and possibilities and
limitations of such commercial chillers will be discussed.
