Abstract: A refrigeration system comprising a compressor (24), a four-way valve (25), an indoor units heat exchanger (26), an outdoor units heat exchanger (27), an expansion valve (29) and characterized in that it comprises a first two-way valve (30) or other shut-off devices, a second two-way valve (31) or other shut-off devices, an expanded addboiler-cooler of liquid and gaseous media (28) containing a housing (1) with cover (2), the liquid circuits inlet orifice (3) and illiquid circuits inlet collector (4), from which a vertical row of a plurality of spiral tubular elements (5) emerges and twisted in a spiral in the direction from a wall of a housing (1 ) to the center and enters by vertical row into the liquid circuits outlet collector (6) having liquid circuits outlet pipe (7), that exits the housing (1) with cover (2) through the liquid circuits outlet orifice (8), wherein the liquid circuits outlet collector (6) has the form of flask through the center of which the gas circuits outlet pipe (12) passes vertically, in which the gaseous media enters through the inlet opening of gas circuits outlet pipe (13) located inside the housing (1) with cover (2) and comes out through the gas circuits outlet pipe (12) and gas circuits outlet orifice (14), wherein the gaseous medium enters the housing (1) with cover (2) through the gas circuits inlet pipe (10), which enters the cover (2) through the gas circuits inlet orifice (9), and then enters between vertically arranged rows of liquid circuits spiral tubular elements (5) through the openings of gas circuits inlet pipe (11) and moves in a spiral relatively parallel between located through one or more rows of liquid circuits spiral tubular elements (5) membranes (17) with liquid taps (18), through which the liquid phase of refrigerant passes in the direction to the lower part of the housing (1) and gaseous phase of refrigerant passes in the direction of the upper part of the housing (1) with cover (2), wherein the rising gaseous medium flows moving direction supported by the upper flow guide rings (19) located in upper cover (2) part, and descending liquid medium flows direction supported by the lower flow guide rings (20) located in the lower housing (1) part, and a part of gas emissions when a liquid media enters the liquid circuits outlet collector (6) are removed inside the housing (1) with cover (2) through the capillary gas pipe (16) located in the upper point of the liquid circuits outlet collector (6), wherein when operation in heat supply mode the refrigerant passes the system elements in the order compressor (24) - four-way valve (25) - indoor units heat exchanger (26) - first two-way valve (30) - expanded addboiler-cooler of liquid and gaseous media (28) - expansion valve (29) - second two-way valve (31) - outdoor units heat exchanger (27) - four-way valve (25) - expanded addboiler-cooler of liquid and gaseous media (28) - compressor (24), and when operation in cold supply mode in the order compressor (24) - four-way valve (25) - outdoor units heat exchanger (27) - second two-way valve (31) - expanded addboiler-cooler of liquid and gaseous media (28) - expansion valve (29) - first two-way valve (30) - indoor units heat exchanger (26) - four-way valve (25) - expanded addboiler-cooler of liquid and gaseous media (28) - compressor (24).
