MULTI-COMPARTMENT TRANSPORT REFRIGERATING SYSTEM WITH ECONOMISER Russian patent published in 2020 - IPC F25B5/02 F25B49/02 

FIELD: refrigerating equipment.

SUBSTANCE: multi-compartment transport refrigerating system comprises a compressor having a suction hole, an exhaust opening and an intermediate inlet opening; heat removal heat exchanger. Through the economiser heat exchanger the first refrigerant flow path and the second refrigerant flow path pass. System also includes first evaporator expansion device; first evaporator, having an inlet connected to the first evaporator expansion device, and an outlet, connected to compressor inlet, second expansion device of evaporator; a second evaporator having an inlet connected to the second expansion device of the evaporator, second evaporator is intended for cooling of second chamber of container; and an economiser expansion device connected to the first refrigerant flow path. First evaporator is intended for cooling of the first chamber of the container. Economizer expansion device directs the coolant from the first refrigerant flow path to the coolant flow second path, and coolant flow second path is connected to intermediate inlet opening.

EFFECT: technical result is possibility of compliance with various requirements for operation of refrigeration system with provision of efficiency of refrigeration cycle without violation of power from rapid increase of suction pressure at compressor.
