Application of NH₃ / CO₂ refrigerant cooling system in a cold storage project

Abstract

Taking a project’s integrated logistics dry port as an example, the advantages and disadvantages of several commonly used refrigerants and their systems are compared and analyzed from safety, environmental protection and energy saving. The technical principles of the NH3 / CO2 refrigerant cooling system are briefly described, and the introduction is also introduced. The refrigeration system selection, equipment configuration and automatic control system scheme of the project refrigerator were provided, which can provide a reference for the selection of the refrigeration scheme of the cold chain project in the future.
