[0052] see figure 1 , is the air conditioning system in the present invention, including an inverter air conditioner 200 , a new energy power supply unit 140 , a battery 110 with a power detection unit 150 , a commercial power supply unit 130 that can switch power supply with the battery 110 , and a control device 120 . The main electrical loads of the inverter air conditioner 200 include the indoor fan 210 , the outdoor fan 220 , the compressor 230 , and the circuit and display mechanism 240 .
[0053] The inverter air conditioner 200 is an air conditioner in which the frequency of the compressor 230 can be changed; or, the inverter air conditioner 200 is an air conditioner in which the frequency of the compressor 230 , the internal fan 210 and the external fan 220 can all be changed.
[0054] The new energy power supply unit 140 is powered by solar energy in this embodiment, and may also be other forms of natural energy, such as wind energy, hydropower energy, biogas energy ...

[0066] see image 3 , The difference between this embodiment and the first embodiment is that step d in the first embodiment is divided into two steps: step d11 and step d12.
[0067] According to the size of the temperature difference and the available power of the storage battery, when the energy-saving mode is selected to run, specifically step d11: according to Table 1 of the storage power-temperature difference relationship, the operating frequency of the compressor is determined.
[0068] Table I,
[0069]
[0070] Among them, Qmax represents the maximum power consumption that the battery can provide for the air conditioner, which refers to the maximum power consumption that the battery can provide for the air conditioner without affecting the service life of the battery and meeting the drive power output;
[0071] Q1 means that the power that the battery can provide for the air conditioner is 0-20% of Qmax;
[0072] Q5 means that the battery that the battery can pr...

[0096] see Figure 4 The main difference between this embodiment and the second embodiment is that the influence of the outdoor air temperature on the outdoor heat exchanger is taken into account, and the power consumption of the outdoor fan is further reduced. When the outdoor unit is running and the outdoor air temperature is lower than the design condition of the air conditioning system, since the heat exchange area of the condenser remains unchanged, the same condensation effect can be achieved by reducing a certain amount of air volume.
[0097] The step d in the second embodiment may also include the following steps, that is, in the above step d12, after the operating speed of the external fan is determined, then step d23 is executed.
[0098] Step d23: Detect the temperature in the middle of the outdoor heat exchanger, determine the correction coefficient K value according to the correction coefficient table 3, and then run step d24;
