Compression system e.g. centrifugal compressor, preferably heat pump, containing or using heat transfer fluid, useful for heat transferring to increase the medium temperature, comprises methyltetrahydrofuran and nonafluorobutyl alkyl ether

摘要

Compression system containing or using a heat transfer fluid, comprises methyltetrahydrofuran and nonafluorobutyl alkyl ether (I). Compression system containing or using a heat transfer fluid, comprises methyltetrahydrofuran and nonafluorobutyl alkyl ether of formula (C 4F 9OR) (I). R : saturated 1-4C alkyl chain. An independent claim is included for a process for heat transferring to increase the medium temperature, where the temperature increased by compression is less than 50[deg] C, using the compression system.
