Document Type and Number:
WIPO Patent Application WO/2020/084725
Kind Code:
A1
Abstract:
In order to provide an air-refrigerant type refrigeration system having an increased system thermal efficiency (COP), this air-refrigerant type refrigeration system, which uses air as a working fluid and generates the necessary coldness through an adiabatic expansion process, uses an expansion turbine compressor unit 1 and is provided with a cold storage tank 5 enabling the operation of a refrigeration unit 9 such that the temperature thereof is in a prescribed temperature range, the cold storage tank 5 being provided to a heat exchange part between the refrigeration unit 9 and the adiabatic expansion process outlet-side of an expansion turbine 2.
