ABSTRACT This invention relates to a highly efficient refrigeration system and process, driven by low-grade heat and operated at pressures substantially below at- mospheric, which provides cooling at temperatures gen- erally within the range from about -12°C to about +15°C. Solutions of normally liquid, mutually soluble compounds, having substantially different boiling points, are em- ployed as refrigerant and absorbent. Typically, the ab- sorbent comprises a distillation bottoms fraction con- taining from about 65 to about 95 mol. % of the higher- boiling compound and the refrigerant comprises a distil- lation overhead fraction containing from about 93 to about 99 mol. % of the lower-boiling compound. Multi-effect modes may be employed. This invention also relates to the use of the aforesaid novel refrigeration system is a modified refrigeration system and process, employing two absorption refrigeration cycles in series operation, the first cycle comprising an ammonia-aqueous ammonia system and the second cycle comprising the aforesaid novel ab- sorption system and process. Heat pumped up in the first ammonia cycle is absorbed in the second cycle by refriger- ant at the coolant temperature achieved therein.
