It is understood that the higher the indoor ambient temperature is, the greater the pressure value of the air conditioning system is, with the same outdoor ambient temperature. After the air conditioner starts to operate, through the running current value, the indoor ambient temperature who acquire the air conditioner, can be according to the accurate operational load and the pressure value of confirming current air conditioning system of the size relation of indoor ambient temperature and indoor ambient temperature threshold value to can be according to the accurate operational current value of adjusting the air conditioner of the operational load and the pressure value of current air conditioning system, and then realize the accurate detection and the control to air conditioning system's pressure value.

It will be understood that if T Inner ring ＜T 1 The pressure of the current air conditioning system is illustratedThe value is not high, the service life and the operation reliability of the compressor cannot be influenced, the system pressure value is not required to be reduced by adjusting the operation current value, and the operation current value is controlled according to a conventional mode. If T is 1 ≤T Inner ring Lasting for a preset time, then showing that current air conditioning system is in the high load state for a long time, there is the risk of the long-time high-pressure operation of compressor, so further acquire outdoor coil temperature, can monitor air conditioning system's pressure value more accurately according to the size relation of outdoor coil temperature and outdoor coil temperature threshold value.
Further, the indoor ambient temperature threshold further comprises a second indoor ambient temperature threshold, the first indoor ambient temperature threshold is smaller than the second indoor ambient temperature threshold, and when T is greater than the first indoor ambient temperature threshold 1 ≤T Inner ring ＜T 2 The preset time length is a first preset time length; when T is 2 ≤T Inner ring The preset time is a second preset time; the second preset time length is less than or equal to the first preset time length; t is 2 Is a second indoor ambient temperature.
It is understood that the higher the indoor ambient temperature is, the higher the operation load of the air conditioning system is, the more likely the risk of high-pressure operation of the compressor occurs, and thus the second preset time period is set to be equal to or less than the first preset time period.
Further, the controlling the operation current value according to the magnitude relation between the outdoor coil temperature and the outdoor coil temperature threshold value includes: if T is Outer plate ＜T Outer plate 1 Controlling the running current value according to a conventional mode; if T Outer plate 1 ≤T Outer plate Controlling the running current value according to the outdoor environment temperature and the exhaust temperature; wherein, T Outer plate Is the outdoor coil temperature; t is a unit of Outer plate 1 Is a first outdoor coil temperature threshold.
It is understood that if T Outer plate ＜T Outer plate 1 If the current outdoor coil temperature is not high, the outdoor environment temperature and the exhaust temperature are lower, so that the outdoor environment temperature and the exhaust temperature do not need to be further detected, and the operation current value can be directly controlled in a conventional mode.

In order to avoid that the normal operation of the compressor can not be maintained when the operation current is too low, the lower limit value of the operation current is set to be negatively correlated with the indoor environment temperature, and the lower limit value of the operation current is negatively correlated with the outdoor coil temperature.
