Résumé

CO2 cooling is gaining interest as a cooling method for scientific equipment such as particle detectors. The merit of using CO2 cooling is a high heat transfer capability resulting in small and efficient cooling channels. To support the many CO2 research projects at CERN and its cooperating institutes, a multipurpose CO2 cooling system named TRACI (Transportable Refrigeration Apparatus for CO2 Investigation) is under development. TRACI is optimized for reduced costs and easy operation while keeping maximal flexibility. A new concept named I-2PACL (Integrated 2 Phase Accumulator Controlled Loop) is developed to minimize the piping and control, while maximizing the operational range for use. Several prototypes have been developed. The first results show that the I-2PACL method works well. An operational range of -35°C to +22°C was measured and a cooling capacity up to 250 watt was reached depending on the cooling temperature. A stable operation was observed with minimum control. Two prototypes have been handed over to clients and the operation of the system turned out to be easy and understandable by the non-expert users. This paper describes the design and test results of the current prototypes and will discuss the plans for the future.
