That is, the temporal operation model may be established by historical data collected during operation. Specifically, the operation parameters of the air conditioning system can be collected in the operation process of the air conditioning system, and the time operation model can be determined according to the collected historical operation parameters. For example, the aforementioned operating parameter T may be collected each time the target temperature is adjustedoutdoor、Tindoor,0、n、TsatAnd m and r, and recording the time required by the indoor environment temperature to reach the target temperature, so that the numerical values of constant coefficients A, a, b, c, d, e and f can be determined through the collected multiple groups of historical data, and a time operation model is further established.
The initial time calculation model, that is, the initial values of the constant coefficients a, b, c, d, e, and f may be set in advance at the time of shipment of the air conditioning system. Of course, the time calculation model may be established directly according to the operation parameters of the air conditioning system during the operation of the air conditioner without being preset.

That is, the user may set the target operation time after setting the target temperature, and then the air conditioning system adjusts the operation parameters of the air conditioning system according to the target temperature and the target operation time set by the user and the time operation model, so that the indoor ambient temperature reaches the target temperature in the target operation time.
Specifically, a target temperature T input by a user is acquiredsetAnd target time τsetThen, the target temperature T is setsetAnd target time τsetSubstituting the time operation model, and adjusting the operation parameters of the air conditioning system to make the equation tauset＝f(Tset,Toutdoor,Tindoor,0,n,TsatM, r, …) is established within a certain error range, so that the indoor ambient temperature can reach the target temperature within the target operation time by controlling the air conditioning system according to the acquired operation parameters.
More specifically, the rotation speed n of the indoor fan, the mass m of the refrigerant in the indoor unit, the operation frequency r of the compressor and the saturation temperature T corresponding to the evaporation or condensation pressure of the indoor heat exchanger in the operation parameters of the air conditioning system can be adjustedsatFor example, the saturation temperature T corresponding to the indoor fan speed n, the refrigerant mass m in the indoor unit, the compressor operating frequency r and the evaporation or condensation pressure of the indoor heat exchangersatThe indoor fan speed n can be adjusted first, if the equation can be established after the indoor fan speed n is adjusted, other parameters are not adjusted, and if the equation cannot be established after the indoor fan speed n is adjusted, the next parameter is continuously adjusted until the equation is established, that is, the target operation time tau can be obtained at the target operation time tausetMake the indoor temperature reach the target temperature Tset。
According to an embodiment of the present invention, as shown in fig. 3, a control method of an air conditioning system includes:
