Résumé

The new organic working pair, 2,2,2-trifluoroethanol (TFE)-N-methylpirolidone (NMP), has some advantages compared with water-lithium bromide and ammonia-water (wide working range as a result of the absence of crystallization, low working pressure, low freezing temperature of the refrigerant and good thermal stability of the mixtures at high temperatures). Meanwhile, it has some negative features (lower boiling temperature difference between TFE and NMP, so a rectifier is needed). Because TFE-NMP has a wide working range and does not cause crystallization, it can be used as the working pair in the self regenerated absorption heat transformer (SRAHT) cycle, which is the generator-absorber heat exchanger (GAX) cycle applied in a heat transformer cycle. In the paper, the SRAHT cycle and its flow diagram are shown and the computing models of the SRAHT cycle are presented.
