TWO-CONTROL JET ENTHALPY-INCREASING OUTDOOR UNIT AND MULTI-SPLIT AIR CONDITIONING SYSTEM

摘要

A two-control jet enthalpy-increasing outdoor unit and a multi-split air conditioning system, the two-control jet enthalpy-increasing outdoor unit comprising: an outdoor heat exchanger (10), a jet enthalpy-increasing compressor (16), a reversing assembly (18), a supercooling device (20), a throttle assembly (22), and a first pipeline (24). A first end and a second end of the reversing assembly (18) are respectively connected to a gas outlet (162) and a gas return port (164), a main heat exchange flow path respectively being connected to a first interface (12) and a second interface (14), a secondary heat exchange flow path being connected to a jet opening (166), the two ends of the throttle assembly (22) respectively being connected to an outlet of the main heat exchange flow path and an inlet of the outdoor heat exchanger (10), one end of the first pipeline (24) being connected to an outlet of the outdoor heat exchanger (10), and the other end being positioned between the throttle assembly (22) and the main heat exchange flow path.
