A solar air conditioner comprises a solar photovoltaic panel, a storage battery charged by the solar photovoltaic panel, a frequency conversion compressor and an air conditioner controller. The control method includes the steps that residual electric quantity of the storage battery is detected; the actual frequency of the frequency conversion compressor is adjusted according to the residual electric quantity. According to the solar air conditioner control method, when the storage battery supplies power to the frequency conversion compressor, the actual frequency of the frequency conversion compressor is adjusted according to the residual electric quantity of the storage battery, as with reducing of the residual electric quantity of the storage battery, the actual frequency of the frequency conversion compressor is adjusted to be reduced, so that electricity consumption is reduced, and service life of the storage battery is prolonged. Moreover, as with gradual reducing of the residual electric quantity of the storage battery, the actual frequency of the frequency conversion compressor is not reduced without limitation, the actual frequency can be reduced to 70% of the target frequency at most, and thus greater influences on the cooling effect or the heating effect of the solar air conditioner are avoided.

Fig. 2 is the flow chart of an embodiment of the control method of solar airconditioning proposed by the invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below with reference to drawings and Examples, the present invention is described in further detail.
The control method of the solar airconditioning of embodiment mono-, the present embodiment, described solar airconditioning mainly by solar energy photovoltaic panel, battery, frequency-changeable compressor and the air-conditioner controller etc. that are charged by solar energy photovoltaic panel form, described control method comprises:
Detect the dump energy of battery.
Regulate the actual frequency of frequency-changeable compressor according to dump energy.
In the time that the dump energy of battery reduces, reduce the actual frequency of frequency-changeable compressor, thereby extend the service time of battery.
When the frequency-changeable compressor of described solar airconditioning can be by storage battery power supply, also can be by mains-supplied time, before detecting the dump energy of battery, also need to detect civil power and whether exist.Specifically tell about the control method of described solar airconditioning below.
Described solar airconditioning also comprises controller for solar, inverter, civil power incoming end etc., shown in Figure 1, solar energy photovoltaic panel is connected with battery by controller for solar, battery is connected with frequency-changeable compressor and air-conditioner controller respectively by inverter, air-conditioner controller is connected with civil power incoming end, air-conditioner controller is connected with controller for solar, and solar energy photovoltaic panel is connected with inverter.
Shown in Figure 2, the concrete steps of the control method of described solar airconditioning are as follows:
Step 01: power-on of air conditioner.
Step 02: air-conditioner controller detects the existence of civil power.
Step 03: if civil power exists, enter step 04;
If civil power does not exist, enter step 05.
Step 04: air-conditioner controller control civil power is frequency-changeable compressor power supply, and returns to step 02.
Civil power transfers to air-conditioner controller by civil power incoming end, and air-conditioner controller control civil power is frequency-changeable compressor power supply.Air-conditioner controller regulates the target frequency that the actual frequency of frequency-changeable compressor is frequency-changeable compressor.
In the time that civil power exists, air-conditioner controller sends charging signals to controller for solar, and controller for solar receives after charging signals, and control solar energy photovoltaic panel is charge in batteries.Controller for solar detects the electric weight of battery, after detecting that accumulator electric-quantity is full of, controller for solar control solar energy photovoltaic panel stops to charge in batteries, then, controller for solar control solar energy photovoltaic panel is air-conditioner controller power supply by inverter, and now, air-conditioner controller is powered by civil power and solar energy photovoltaic panel simultaneously, thereby reduce commercial power supply, reached the object of energy saving.In air-conditioner controller, be provided with rectification circuit, the alternating current of input can be converted to direct current, use for air-conditioner controller.
Step 05: controller for solar control battery is frequency-changeable compressor power supply, and controller for solar detects the dump energy of battery, and is transferred to air-conditioner controller, enters step 06.
In the time that civil power does not exist, do not have civil power to transfer to air-conditioner controller, air-conditioner controller sends discharge signal to controller for solar, controller for solar receives after discharge signal, controlling battery discharges to inverter, the direct current of battery output is converted to alternating current by inverter, and offer frequency-changeable compressor use.
Controller for solar detects the dump energy of battery in real time, and is transferred to air-conditioner controller.
Step 06: air-conditioner controller regulates the actual frequency of frequency-changeable compressor according to the dump energy of battery, and returns to step 02.
