Being the manner which operates the closed circuit steam compressed type refrigeration system which includes

摘要

This invention regards the operational method of the closed circuit steam compressed type refrigeration system. As for this system, as it can operate by super critical pressure in high-tension side, the heat sink where 1 compressors (1), 1 radiators (2), 2 are connected at least at least at least in parallel (4), at least the variable expansion expedient 1 where each heat sink (4) is provided on high-level side the sensor of (3), and 1 sets (9 ' and 15) it was connected, to control variable expansion expedient in order (3) the control unit 1 (8 ) it possesses at least. Variable expansion expedient (3) passes by each flow of the refrigerant where control unit (8It is controlled) by. Control unit (8 ), in order to maintain control parameter in the setting range variable expansion expedient the flow of the refrigerant where (3) passes by each cooperation it fiddles. The result of control excessive filling up which it occurs is eased on low-tension side of the system. Furthermore, it is expressed concerning the refrigeration system which is based on the steam compressed circuit which closes.
