[0063] SUMMARY

[0064] With the transformation of global energy structure, renewable energy has become an important development direction of household appliances. Photovoltaic air conditioner is a new energy utilization system combining photovoltaic power generation technology and air conditioning system. Its core is to convert solar energy directly into electricity through photovoltaic modules to provide clean energy for air conditioning equipment. In its development process, different series of operation modes have been derived to cope with complex application scenarios. Among them, the pure photovoltaic air conditioner directly uses photovoltaic power generation to provide power for the air conditioner without equipping with battery and other energy storage devices. The characteristics of this system are immediate use, that is, only when the light is sufficient and the photovoltaic module generates electricity, the air conditioner can run; while in cloudy, night or insufficient light conditions, the air conditioner cannot work normally. During the operation of the photovoltaic air conditioner, due to the change of weather factors (such as light intensity), the air conditioning equipment is prone to run in a non-rated power state, and even the phenomenon of frequent start-stop occurs, which leads to the increase of equipment failure rate. Therefore, the present application proposes a control method for the current pure photovoltaic mode running air conditioning equipment, aiming to reduce the phenomenon of frequent start-stop, reduce the equipment failure rate, and improve the stability and user comfort of the system.

[0065] Therefore, it is necessary to provide a photovoltaic air conditioning system and a control method thereof to solve the above problems.

[0066] Based on the above inventive concept, the photovoltaic air conditioning system and the control method thereof provided by the embodiments of the present specification will be described exemplarily.

[0067] Exemplary methods

[0068] The embodiments of the present specification provide a photovoltaic air conditioning system, as shown in Figure 1 The system comprises:

[0069] The photovoltaic module 101, the air conditioner module 102, the signal acquisition module 103 and the air conditioner control module 104, the photovoltaic module 101 is used for converting light energy into electric energy, and the air conditioner module; the air conditioner module 102 is used for temperature regulation according to the electric energy provided by the photovoltaic module; the signal acquisition module 103 is used for acquiring the working parameters of the photovoltaic module and transmitting to the air conditioner control module 104, the signal acquisition module 103 can also acquire the working parameters of the air conditioner module; the air conditioner control module 104 is used for determining the operation strategy of the air conditioner module according to the working parameters of the photovoltaic module, and controlling the air conditioner module 102 to carry out temperature regulation based on the operation strategy, the system can also include power adjustment module, for correcting the power of the output electric energy of the photovoltaic module 101, the power adjustment module can be a capacitor, also can be a battery, can temporarily store electric energy when the output electric energy of the photovoltaic module is higher than the demand, and appropriately supplement the electric energy when the output electric energy is insufficient, the direct current conversion module, i.e. DC module, can be included in the photovoltaic module 101, the module can convert the unstable direct current output by the photovoltaic module into the stable voltage level (such as 220V) required by the air conditioner module, to ensure the power demand of the start and operation of the air conditioner module. According to the maximum power point tracking method (Maximum Power Point Tracking, MPPT), the output state of the photovoltaic module can be optimized to make it suitable for the voltage level of the air conditioner module, and also make it always work at the maximum power point, so as to improve the energy conversion efficiency.

[0070] The embodiment of the present specification provides a control method of a photovoltaic air conditioner system, as shown in Figure 2 The embodiment of the present specification provides a control method of a photovoltaic air conditioner system, as shown in

[0071] S201, acquiring the working parameters of the photovoltaic module.

[0072] In specific implementation, the working parameters of the photovoltaic module are acquired, that is, the power generation conditions of the photovoltaic module are acquired, so as to make subsequent strategy decision, specifically, the working parameters include the output voltage of the photovoltaic module and the output power of the photovoltaic module.

[0073] Before acquiring the working parameters, the photovoltaic power generation factor information such as the light intensity information and other factors can be acquired first, the photovoltaic module is started when the photovoltaic power generation factor information meets the preset condition, if the photovoltaic power generation factor information does not meet the preset condition, that is, it is considered that the photovoltaic module cannot continuously generate stable photoelectric current, then the air conditioner module is in a starting state, and the electric energy generated by the photovoltaic module is first transmitted to the power adjustment module.

[0074] S202, determining the operation strategy of the current air conditioner module based on the working parameters.

[0075] In a specific implementation, the operation strategy of the air conditioning module is determined according to the working parameters obtained in the above steps. Specifically, the operation strategy can include an air conditioning energy-saving strategy and an air conditioning operation strategy. Specifically, when the output voltage is not higher than the starting voltage of the air conditioning module or the output power is less than the starting power of the air conditioning module, the operation strategy is determined to be the air conditioning energy-saving strategy. In the energy-saving strategy, the air conditioning module only consumes a small amount of power to fine-tune the temperature. When the output voltage is higher than the starting voltage of the air conditioning module and the output power is not less than the starting power of the air conditioning module, the operation strategy is determined to be the air conditioning operation strategy. In the operation strategy, the air conditioning module normally performs refrigeration or heating.

[0076] Further, according to different specific working parameters, the air conditioning energy-saving strategy and the air conditioning operation strategy can be further divided into a first air conditioning energy-saving strategy, a second air conditioning energy-saving strategy, and a third air conditioning energy-saving strategy, and a first air conditioning operation strategy and a second air conditioning operation strategy. When the indoor temperature data is less than a first temperature threshold, the operation strategy is determined to be the first air conditioning energy-saving strategy. When the indoor temperature data is greater than or equal to the first temperature threshold and less than or equal to a second temperature threshold, the operation strategy is determined to be the second air conditioning energy-saving strategy. When the indoor temperature data is greater than the second temperature threshold, the operation strategy is determined to be the third air conditioning energy-saving strategy. The first temperature threshold is the lowest temperature that meets the demand, and the second temperature threshold is the highest temperature that meets the demand. The specific values can be set according to actual needs, and the embodiments of the present application do not limit this. Here, for convenience of description, the first temperature threshold is 20 degrees, and the second temperature threshold is 27 degrees. That is, when the room temperature is less than 20℃, the fan and the electric heating function in the air conditioning module are started. When the room temperature is higher than 27℃, only the fan in the air conditioning module is started. If the indoor temperature is between 20℃ and 27℃, the air conditioning module is in standby, the photovoltaic module adjusts the irradiation angle, and the light is abandoned.

[0077] When the operation strategy is the air conditioning operation strategy, the strategy can be further divided according to the working power of the air conditioning. Specifically, the predicted power of the air conditioning module in response to the user's instruction is first obtained, that is, the working power of the air conditioning that meets the user's setting. When the output power is not less than the predicted power, the operation strategy is determined to be the first air conditioning operation strategy. When the output power is less than the predicted power, the operation strategy is determined to be the second air conditioning operation strategy.

[0078] S203, controlling the air conditioning module to perform temperature regulation based on the operation strategy of the air conditioning module.

[0079] In a specific implementation, the air conditioning module is controlled to work according to the operation strategy determined in the above steps. Specifically, when the operation strategy is the air conditioning energy-saving strategy, the air conditioning module is controlled to be in a standby state. When the operation strategy is the air conditioning operation strategy, the air conditioning module is operated.

[0080] Furthermore, when the operating strategy is the first air conditioning energy-saving strategy, the fan function and electric heating function of the air conditioning module are operated; when the operating strategy is the second air conditioning energy-saving strategy, the air conditioning module is controlled to be in a standby state; and when the operating strategy is the third air conditioning energy-saving strategy, the fan function of the air conditioning module is operated. When the operating strategy is the first air conditioning operation strategy, the air conditioning module is operated normally; when the operating strategy is the second air conditioning operation strategy, the air conditioning module is operated using the output power as the operating power.

[0081] In addition, when the output voltage is higher than the starting voltage of the air conditioning module but the output power is lower than the starting power, the output power is continuously monitored until the output power is no lower than the starting power.

[0082] The specific execution steps of the control method of the photovoltaic air conditioning system in this embodiment are as follows: Figure 3 As shown, after the PV AC system starts, it determines whether the current light intensity and other factors of the PV module meet the requirements for continuous and stable operation. If the PV module cannot continuously generate a stable photocurrent, the PV AC unit enters a waiting state. Then, based on the voltage and current constraints of the DC module input, the electrical energy is converted by the DC module to a voltage level (VO) suitable for the AC module. At this point, it is necessary to determine whether the DC module output voltage level meets the AC module's startup voltage (VStart). If the converted voltage by the DC module is insufficient to support or meet the AC module startup requirements (i.e., VO ≤ VStart), the operating strategy is the AC energy-saving strategy.

[0083] Assume that the air conditioning module startup power is Pstart, the real-time power during air conditioning operation is Pempty, and the real-time output power of the DC module is PO. If the voltage converted by the DC module VO > Vstart, and the power PO ≥ Pstart, the operation strategy is the air conditioning working strategy.

[0084] In an example, assuming that the starting voltage and starting power of the photovoltaic module of any photovoltaic air-conditioning system are 20V and 50W respectively, the starting voltage of the air-conditioning module is between 176V and 264V, and the starting power Pstart of the air-conditioning module is 800W.

[0085] At a certain moment, during the operation of the photovoltaic air-conditioning system, the operating power of the air-conditioning module corresponding to the user's command is 2000W, the output voltage of the photovoltaic module is 40V, and the output power is 5000W. After the DC module adjusts the output voltage and maximum output power, the output is 220V and 4000W, which meets the startup conditions of the air-conditioning module. The user-commanded power is less than the output power of the DC module. At this time, the strategy is the first air-conditioning operation strategy, and the photovoltaic air-conditioning system operates according to the user-commanded mode.

[0086] At a certain moment, the working power of the air conditioner module corresponding to the user's instruction is 3000W in the operation process of the photovoltaic air conditioning system, the output voltage of the photovoltaic module is 30V, the output power is 3000W, the photovoltaic module reaches the starting condition, the output of the DC module after adjusting the output voltage and the maximum output power is 220V and 2500W, which meets the starting condition of the air conditioner module, but the user instruction power is greater than the output power of the DC module, at this time the strategy is the second air conditioner working strategy, then the photovoltaic air conditioning system operates according to the user instruction mode with the actual power of 2500W;

[0087] At a certain moment, the indoor temperature is 17℃, the user's instruction power is 1000W in the operation process of the photovoltaic air conditioning system, the output voltage and power of the photovoltaic module are 20V and 1000W, the photovoltaic module reaches the starting condition, the output of the DC module after adjusting the output voltage and the maximum output power is 220V and 700W, which does not meet the starting condition of the air conditioner unit, after charging the super capacitor for several minutes, the output of the DC module after adjusting the output voltage and the maximum output power is 220V and 750W, at this time the strategy is the first air conditioner energy-saving strategy, the fan and the electric auxiliary heating function are started.
