1. A multi-split system with partitioned control, comprising:
a compressor (1), an outdoor heat exchanger (2), two indoor unit sets (3), a first four-way valve (4), a second four-way valve (5), and a third four-way valve (6), wherein each of the indoor unit sets (3) is composed of two or more indoor units (3) arranged in parallel;
an output end of the compressor (1) is respectively in communication with first interfaces (D) of the first four-way valve (4), the second four-way valve (5), and the third four-way valve (6),
a third interface (C) of the first four-way valve (4) is in communication with a first end of the outdoor heat exchanger (2),
a second interface (E) of the second four-way valve (5) is in communication with a first end of one indoor unit set (3) therein,
a third interface (C) of the third four-way valve (6) is in communication with a first end of the other indoor unit set (3), and
a second end of the outdoor heat exchanger (2) is in communication with second ends of the indoor unit sets (3) in a convergence manner;
additional interfaces of the second four-way valve (5) and the third four-way valve (6) are all in communication with a return end of the compressor (1); and
by independently adjusting power on/off actions of the second four-way valve (5) and the third four-way valve (6), a heating mode or a cooling mode of each indoor unit set (3) is controlled correspondingly and independently.
