Résumé

When used in traditional pool-boiling type refrigeration cycles, non-azeotropic mixed refrigerants tend to result in a reduced efficiency compared to pure refrigerants. This results from the composition shift effect, which distributes the mixture components: concentrating the more volatile component in the high pressure part of the cycle, and the less volatile component in the low pressure part. The obvious effect of this is to increase the compression ratio relative to a single component. This article investigates a way of manipulating the composition change of a refrigerant mixture, using two components of similar volatility, in order to reduce the compression ratio. Counter-current vapour-liquid contact is used in a "refrigeration column", which is combined with a distillation column. The cycle is able to exploit heat sources below 100 °C as input to the distillation column and the designer is able to optimise the consumption of compressor power and distillation heat input.
