摘要： A multi-mode water-fluorine multi-split system, comprising refrigerant circulation loops (101) of multiple air conditioning units (100), an outdoor heat exchanger (102) and an indoor heat exchanger (103), and further comprising a first circulation loop (200), a second circulation loop (300) and a primary heat exchanger (3). The first circulation loop (200) and the second circulation loop (300) exchange heat with one another by means of the main heat exchanger (3), a second medium channel (105) is provided in each of the outdoor heat exchanger (102) and the indoor heat exchanger (103), and the first circulation loop (200) and the second circulation loop (300) can, by means of each second medium channel (105), exchange heat with a first medium channel (104) and/or a first air heat exchange channel (107) in each outdoor heat exchanger (102), and with the second medium channel (105) and/or a second air heat exchange channel (106) in each indoor heat exchanger (103). The present system can achieve high-efficiency utilization of natural energy, energy recovery, defrosting, and free dispatch of cold and heat energy among various systems, improving operation efficiency under a small load, and ensuring that an air conditioning system can be stably and efficiently operated throughout the year.
