ABSTRACT:
In one aspect, the invention comprises a pneumatic refrigeration system having a compressor for generating a pressure increase in an air flow, a system expander downstream of the compressor for reducing the temperature of the air flow and a recycling conduit downstream of the system expander for conducting at least a part of the air flow toward the compressor. In another aspect, the invention comprises a method for cooling a refrigerant including the steps of compressing the refrigerant in a compressor, expanding a first portion of the refrigerant, exchanging heat between the first portion of the refrigerant and a second portion of the refrigerant; and expanding the second portion of the refrigerant. One object of the invention is to provide an efficient pneumatic refrigeration system which contains the air flow to reduce the likelihood of contamination by the refrigerated air.
