Type of monograph: Guide/Handbook


As a consequence of the EU regulation 517/2014 (F-gas), the future synthetic refrigerants with a low global warming potential will be to a large degree nonazeotropic mixtures with a significant temperature glide (some over 6 K). These refrigerants change temperature during the evaporating and condensing process at constant pressure. Many works comparing the performances of different refrigerants have been published referring to mid-point temperature where no evident correlation between mid-point and pressure can be easily determined. The scope of this guideline is to give an overview of the relation between the dew and mid temperature for non-azeotropic mixtures, highlight the difference in performance and give a recommendation for converting the performance of the compressor regulated by the existing standards to mid-temperature performance. In this case, any misunderstanding and wrong interpretations of the result are avoided.
