Abstract

A refrigeration system using air as the refrigerant comprises a compressor which compresses air to 84 bar g. The compressed air is cooled first by cooling water and then by returning air in a plate-fin heat exchanger before being expanded to 59 bar g in an expander. The expanded air at -61.degree. C. is passed through indirect cooling coils in a cold store which it leaves at -45.degree. C. This air is then passed through the plate-fin heat exchanger before being recycled to the compressor. The refrigeration delivered is about 1.05 kw refrigeration/kw power input.
