Abstract
In a heat transfer system and a method for operating a heat transfer system, a heat transfer fluid having a phase change material (PCM) circulates in a cooling circuit. A combined state of phase value of the heat transfer fluid is determined based on information obtained from a sensor system including a temperature sensor and an electrical resistance sensor realized as two separate sensors or as one combined temperature-and-electrical-resistance sensor. The system and method can securely and effectively prevent a possible blocking of the channels of an indoor heat exchanger of the system by solidified PCM and an unwanted deposition of solid PCM (crystals) on heat transfer surfaces of the indoor heat exchanger.
