HEAT SOURCE UNIT OF COOLING SYSTEM, AND COOLING SYSTEM Russian patent published in 2010 - IPC F25B29/00 

FIELD: heating.

SUBSTANCE: heat source unit of cooling system includes circuit (12) of heat source. Circuit (12) includes the first gas port (31) continuously interconnected with delivery side of compressor (14), the second gas port (32) continuously interconnected with suction side of compressor (14), the third gas port (33) selectively interconnected with one of the first gas line (25) and the second gas line (26), liquid port (34) continuously interconnected with the end of liquid inlet/outlet of heat exchanger (15) of heat source, the first switching mechanism (17) which switches over the state of interconnection of the end of liquid inlet/outlet of heat exchanger (15) of heat source, and the second switching mechanism (18) which switches over the state of interconnection of the third gas line (27). Cooling system includes unit (10) of heat source of system (5) and unit (7) of heat consumption, which has circuit (8) of heat consumption, which includes pressure reducing mechanism (41) and heat consumption heat exchanger (40). Circuit (9) of cooling agent has been created with the connection of the third gas port (33) of circuit (12) of unit (10) of heat source and the gas inlet/outlet end of heat consumption circuit (8) and as the connection of liquid port (34) of circuit (12) and the liquid inlet/outlet end of heat consumption circuit (8).

EFFECT: possibility of using auxiliary heat exchanger both in cooling and heating modes.
