Résumé

A hybrid cabinet cooler, which has operating modes of vapour compression and natural circulation, is designed for the cooling unit of an outdoor telecommunication system. The performance of the system in the both operating modes was measured by varying refrigerant charge and operating conditions. Since each operating mode shows different optimal charges, it is required to control refrigerant charge amount based on the mode change. The natural circulation cycle yielded approximately 95% of cooling capacity of the vapour compression cycle. The instability of the natural circulation cycle was observed, which should be considered as an important design parameter.
