Goals was to install a central refrigeration system. For these purposes, one refrigeration unit is used: a multi-compressor based on reciprocating semi-hermetic compressors with a condenser / air-cooled gas cooler. The system has three suction lines for different boiling points
(-39 ° C, -27 ° C and -8 ° C).
R744 (carbon dioxide, CO2) is used as a refrigerant. The transfer of cold to the consumer is carried out by air coolers with direct boiling of the refrigerant, located in the cooled rooms. Maintenance of the set temperatures in chambers is carried out automatically by means of devices and fittings which are mounted on pipelines. The total required installed capacity of refrigeration equipment is 80.17 kW.
