Claim 7:
8. The control method of the multi-connected heat recovery air conditioning system according to claim 1, characterized in that during the operation in the heating mode, heat recovery mode, or hot water production mode, the blade speed of the outdoor heat exchanger is adjusted according to the low pressure value P1, wherein in response to the low pressure value P1>1.0 MPa, the blade speed is reduced; in response to 0.6 MPa≤the low pressure value P1≤1.0 MPa, the blade speed is maintained at the rated speed; in response to the low pressure value P1<0.6 MPa, the blade speed is increased.
