FIELD: refrigerating facilities. SUBSTANCE: refrigerating installation has evaporator, two-stage turbocompressor set, condenser and throttling device, all placed in main line of cooling agent. Condenser is connected also to turbocompressor set cooling system through auxiliary line, cooling system being placed in communication with input of turbocompressor second stage. Installation has auxiliary and main regenerative heat exchangers connected in direction of cooling agent flow to main line after condenser, and additional line with temperature control valve. Auxiliary heat exchanger is connected by cooling medium line to auxiliary line. Additional line is connected to auxiliary line before cooling system and after cooling system before input of auxiliary heat exchanger. Cooling medium line of main heat exchanger is connected to main line after evaporator. Temperature control valve provides control of flow in auxiliary line at output of auxiliary heat exchanger. EFFECT: enlarged operating capabilities. 3 cl, 3 dwg
