[0039] In order to make the objects, technical solutions and advantages of the application clearer, the technical solutions of the application will be described clearly and completely below in combination with specific embodiments of the application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0040] According to an embodiment of the present application, a control method of a photovoltaic air conditioner is provided, as shown in Figure 1 The flowchart of an embodiment of the method of the present application is shown. The power supply of the photovoltaic air conditioner includes a photovoltaic power generation system having a photovoltaic panel; the photovoltaic air conditioner includes a fresh air pipe and an exhaust air pipe, an activated carbon adsorption device arranged at the exhaust air pipe, an ozone generator arranged at the outdoor side of the photovoltaic air conditioner, and an ultraviolet light generator arranged at the indoor side of the photovoltaic air conditioner; the activated carbon adsorption device can adsorb ozone; the ozone generator can electrolyze oxygen in outdoor air to generate ozone under the power supply of the photovoltaic power generation system, and the ozone can enter the indoor unit of the photovoltaic air conditioner through the fresh air pipe or purify the indoor air of the room where the photovoltaic air conditioner is located, and then be discharged to the outdoor through the exhaust air pipe; the ultraviolet light generator can decompose ozone in the room where the photovoltaic air conditioner is located into oxygen. In the scheme of the present application, as shown in Figure 1 The control method of the photovoltaic air conditioner includes steps S110 to S140.

[0041] At step S110, after the photovoltaic air conditioner is started, if the air purification function of the photovoltaic air conditioner is turned on, the output voltage of the photovoltaic panel is obtained, the activity of the user in the room where the photovoltaic air conditioner is located is obtained, and the ozone concentration in the room where the photovoltaic air conditioner is located is obtained.

[0042] At step S120, if it is necessary to generate ozone by using the ozone generator, the power supply mode of the photovoltaic power generation system is controlled and the rate of ozone generation of the ozone generator is controlled according to the output voltage of the photovoltaic panel, so as to generate ozone by using the ozone generator. In some embodiments, the power supply mode of the photovoltaic power generation system is controlled and the rate of ozone generation of the ozone generator is controlled according to the output voltage of the photovoltaic panel in step S120, including at least one of the following, i.e., at least one of the following control cases:

[0043] The first control case: if the output voltage of the photovoltaic panel is greater than a preset first voltage threshold and less than a preset second voltage threshold, the power supply mode of the photovoltaic power generation system is controlled to be the power supply mode of the photovoltaic panel, and the current power of the ozone generator is controlled to be a set power to make the current generation rate of the ozone generator be a preset generation rate; wherein the output voltage of the photovoltaic panel is the power supply voltage UDC of the photovoltaic panel, the preset first voltage threshold is U 过低保护 , and the preset second voltage threshold is U 高压 .

[0044] The second control scenario: if the output voltage of the photovoltaic panel is greater than or equal to the preset second voltage threshold and less than the preset third voltage threshold, the power supply mode of the photovoltaic power generation system is controlled to be the power supply mode of the photovoltaic panel, and the current power of the ozone generator is controlled to be greater than the set power so that the current generation rate of the ozone generator is higher than the preset generation rate; wherein the preset third voltage threshold is U 过高保护 The preset third voltage threshold is generally determined by the maximum input voltage of the household photovoltaic inverter. The maximum input voltage of a common household photovoltaic inverter is 600VDC, so the overvoltage protection range is 110% to 130%, that is, the voltage range of 660VDC-780VDC can be used as the range of the preset third voltage threshold.

[0045] A third control scenario: The photovoltaic power generation system also includes a battery. If the output voltage of the photovoltaic panel is greater than or equal to a preset third voltage threshold, the compressor of the photovoltaic air conditioner is shut down for protection until the output voltage of the photovoltaic power generation system decreases below the preset third voltage threshold, at which point the compressor is restarted. The photovoltaic power generation system is powered by the photovoltaic panel and charges the battery. Furthermore, the current power of the ozone generator is controlled to be greater than a set power so that the current ozone generation rate exceeds a preset rate. Initially, because the photovoltaic panel's power is directly supplied to the system without being diverted to the battery, the voltage relationship is UDC = Usystem. Therefore, the output voltage of the photovoltaic panel is equal to the input voltage of the system. Excessive voltage triggers overvoltage protection, protecting the system's compressor. A threshold is set as the condition for diverting voltage to the battery, meaning that the excess voltage is used to charge the battery. The voltage relationship should be UDC = Usystem + Ubattery.

[0046] Fourth control scenario: The photovoltaic power generation system also includes a battery. If the output voltage of the photovoltaic panel is less than or equal to a preset first voltage threshold, the compressor of the photovoltaic air conditioner is controlled to shut down for protection until the output voltage of the photovoltaic power generation system increases to a value greater than the preset first voltage threshold, at which point the compressor is restarted. The photovoltaic power generation system is powered by the battery, and the current power of the ozone generator is controlled to be less than a set power so that the current generation rate of the ozone generator is lower than a preset generation rate. Due to insufficient power from the photovoltaic panel, the battery is connected for shared power supply, and the voltage relationship at this time is Usystem = UDC + Ubattery, which is greater than the preset first voltage threshold.

[0047] The scheme of the present application is provided with an exhaust pipe and a fresh air pipe for a photovoltaic air conditioner, and the indoor air is updated by the way of air exchange, and the air conditioner itself can realize the function without adding new equipment, saving space, and the object is the indoor air. The bidirectional air exchange pipeline is assembled with the indoor unit of the photovoltaic air conditioner. Figure 13 It is a schematic diagram of the assembly structure between the bidirectional air exchange pipeline and the indoor unit of the photovoltaic air conditioner. As shown in Figure 13 The exhaust pipe 7 is installed in the air conditioner shell 11 through the exhaust pipe interface 14, the fresh air pipe 8 is installed in the air conditioner shell 11 through the fresh air pipe interface 9, the air exchange fan 10, the activated carbon module 12 and the piston motor 13 are all installed in the air conditioner shell 11. Figure 7 It is a schematic diagram of the control logic of the photovoltaic air conditioner for executing the air purification function. As shown in Figure 7 The control logic of the photovoltaic air conditioner for executing the air purification function includes:

[0048] Step 1, the photovoltaic air conditioner starts, and then step 2 is executed, that is, the air purification function is executed.

[0049] Step 2, the photovoltaic air conditioner executes the air purification function, and then step 3 is executed, that is, the ozone removal function is executed.

[0050] In step 2, the photovoltaic air conditioner executes the air purification function, which includes step 21 and step 22.

[0051] Step 21, in the ozone generator outside, the photovoltaic power supply system provides photovoltaic power to electrolyze the oxygen in the outdoor air to generate ozone, and the generation rate of ozone is affected and controlled by the voltage of the photovoltaic power supply. In step 21, the specific process of controlling the generation rate of ozone according to the voltage of the photovoltaic power supply includes: obtaining the supply voltage UDC of the photovoltaic panel in the photovoltaic power generation system at this time in real time, and comparing the supply voltage UDC of the photovoltaic panel with different set values, and determining the working state of the battery in the photovoltaic power generation system according to the comparison result, and determining the power supply source of the control system of the photovoltaic air conditioner. For details, please refer to the related descriptions of steps 211, 212, 213 and 214.

[0052] Step 211, the voltage value of the supply voltage UDC of the photovoltaic panel at this time is detected to obtain the UDC voltage, if U 过低保护 <UDC voltage<U 高压 The supply voltage UDC of the photovoltaic panel at this time is in the normal range, which indicates that the weather condition is good, the photovoltaic panel can supply power normally, and the ozone generation rate is the normal rate set, that is, the ozone is generated at the normal rate set. Among them, U 过低保护 such as 120VDC, U 高压 can be taken to 100%-105%, that is, 600VDC-630VDC.

[0053] Step 212, when U 高压 ≤ UDC voltage < U 过高保护 , it indicates that the photovoltaic panel power supply voltage is large at this time, which can provide sufficient energy for the photovoltaic air conditioner control system, at this time, the power of the outdoor ozone generator is increased, the ozone generation rate is increased, the ozone concentration is increased, the indoor air purification effect is better, and the purification time is less. Among them, the way to increase the power of the outdoor ozone generator can be to increase the voltage of the outdoor ozone generator, that is, the input voltage, mainly to increase the amplitude of the voltage.

[0054] Step 213, when U 过高保护 ≤ UDC voltage, it indicates that the photovoltaic panel power supply voltage exceeds the demand of the photovoltaic air conditioner control system, at this time, the compressor of the photovoltaic air conditioner will enter the shutdown protection to prevent damage and ensure the reliability of the photovoltaic air conditioner control system, and the Maximum Power Point Tracking (MPPT) controller in the photovoltaic power generation system will guide the voltage exceeding the demand of the photovoltaic air conditioner to the outdoor ozone generator and the battery, and the battery will switch to the charging state. At the same time, the ozone generation rate generates ozone according to the generation rate in step 212 to achieve a better indoor purification effect. After matching the power supply voltage to the demand voltage of the photovoltaic air conditioner control system, the compressor of the photovoltaic air conditioner is restarted.

[0055] Step 214, when UDC voltage ≤ U 过低保护 , it indicates that the weather condition is poor at this time, and the photovoltaic panel power supply is less. At this time, the compressor of the photovoltaic air conditioner enters the shutdown protection to prevent damage and ensure the reliability of the photovoltaic air conditioner control system, and the battery switches to the working state to meet the demand of the photovoltaic air conditioner control system working voltage. At the same time, the outdoor ozone generator will run in a low-power state, the ozone generation rate will slow down, and the purification time will be extended to ensure that the battery has enough power to supply the photovoltaic air conditioner for all-weather operation. After the photovoltaic power generation system switches from photovoltaic power supply to battery power supply, the compressor of the photovoltaic air conditioner is started. Among them, the ozone generator mainly decomposes oxygen into oxygen atoms through a high-voltage electric field, and these oxygen atoms combine with undecomposed oxygen to form ozone. When the photovoltaic power supply voltage is low, the input voltage of the ozone generator is also reduced, so the amplitude of the voltage is reduced, the electric field strength is weakened, the decomposition rate of oxygen atoms is slowed down, and the ozone generation rate is slowed down.

[0056] In the scheme of the present application, the power source of the control system of the photovoltaic air conditioner is derived from the outdoor photovoltaic power generation system, the photovoltaic power generation system is self-consumed, the photovoltaic power generation system electrolyzes oxygen to generate ozone which is sent into the room for air purification, according to the different power supply voltage, the power supply source is adjusted, the ozone generation rate is adjusted, the indoor comfort and energy saving requirements are ensured, and the reliability of the control system of the photovoltaic air conditioner is ensured.

[0057] At step S130, in the case that the ozone generator has generated ozone, according to the user activity situation of the room where the photovoltaic air conditioner is located, the opening and closing of the fresh air pipe and the exhaust pipe are controlled, and the way in which the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner or the room where the photovoltaic air conditioner is located is controlled, so as to purify the indoor air of the photovoltaic air conditioner by using the ozone generated by the ozone generator, specifically, by using the ozone generated by the ozone generator to enter through the fresh air pipe to purify the indoor air of the photovoltaic air conditioner. In some embodiments, the user activity situation of the room where the photovoltaic air conditioner is located includes the case that the room where the photovoltaic air conditioner is located has a user, or the case that the room where the photovoltaic air conditioner is located has no user. In step S130, according to the user activity situation of the room where the photovoltaic air conditioner is located, the opening and closing of the fresh air pipe and the exhaust pipe are controlled, and the way in which the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner or the room where the photovoltaic air conditioner is located is controlled, including at least one of the following, that is, including at least one control situation in any of the following control situations:

[0058] The first control situation: if the room where the photovoltaic air conditioner is located has a user, the fresh air pipe and the exhaust pipe are both opened, so that the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner through the fresh air pipe, and then is discharged from the exhaust pipe without directly entering the room where the photovoltaic air conditioner is located.

[0059] The second control situation: if the room where the photovoltaic air conditioner is located has no user, the fresh air pipe is opened and the exhaust pipe is closed, so that the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner through the fresh air pipe, and then directly enters the room where the photovoltaic air conditioner is located. After a period of time, the exhaust pipe is opened, so that the ozone and its reactants in the room where the air conditioner is located are discharged outdoors.

[0060] Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner for performing the air purification function further includes: step 22, after generating ozone outdoors, sending the ozone generated outdoors into the room for air purification, and performing classified control according to the human activity situation in the room.

[0061] In step 22, in the case of people in the room, the fresh air pipeline and the exhaust pipeline of the photovoltaic air conditioner are opened, so that the ozone generated outdoors enters through the fresh air pipeline and is discharged through the exhaust pipeline, so that the ozone does not enter the room, and the indoor air is updated through the double air exchange of the fresh air pipeline and the exhaust pipeline.

[0062] In step 22, in the case of no people in the room, the ozone is sent into the room, and after the ozone purifies the indoor air, the fresh air pipeline and the exhaust pipeline are opened, the ozone and the related reactants are discharged from the room, and the fresh air is sent into the room, so that a better purification effect is achieved.

[0063] In step 22, in the case of no people in the room, the ozone is sent into the room, and after the ozone purifies the indoor air, the fresh air pipeline and the exhaust pipeline are opened, the ozone and the related reactants are discharged from the room, and the fresh air is sent into the room, so that a better purification effect is achieved.

[0064] In the case of people, ozone is not introduced into the room, and indoor air is replaced by double air exchange, that is, fresh air is sent into the room, and indoor dirty air is discharged from the room through the exhaust pipe, and the two processes are carried out simultaneously. Figure 12 At this time, valves 1, 3, 4 and 6 are closed, and valves 5 and 2 are opened, which can also achieve the replacement of indoor air and the cleaning of indoor air quality. The flow rate of the fresh air introduced should be slightly larger than the flow rate of the air discharged, so that the indoor pressure is slightly positive, which can be achieved by adjusting the opening degree of the valve. The larger the opening degree, the larger the flow rate, and the smaller the opening degree, the smaller the flow rate. The significance of the slight positive pressure is to prevent unfiltered pollutants or harmful gases in the outdoor air from entering the room, which helps to maintain stable air quality and comfort in the room.

[0065] In the case of no people, ozone is introduced, and in combination with Figure 12 Valves 1, 2, 3 and 5 are closed, and valves 4 and 6 are opened, ozone is introduced to purify the air, after a period of time, valves 4 and 6 are closed, valves 1, 2 and 5 are opened, fresh air is introduced, and indoor dirty air is discharged through the exhaust pipe. The unreacted ozone is recovered into the ozone storage device. The flow rate of the fresh air introduced should be slightly larger than the flow rate of the air discharged, so that the indoor pressure is slightly positive, which can be achieved by adjusting the opening degree of the valve. The larger the opening degree, the larger the flow rate, and the smaller the opening degree, the smaller the flow rate.

[0066] The scheme of the present application proposes a control scheme of a photovoltaic air conditioner, which purifies the air by using ozone, increases the system structure of the fresh air pipeline and the exhaust pipeline, adjusts the air conditioner function operation logic, improves the indoor air quality, and fills the shortcoming of the air conditioner in the related scheme.

[0067] At step S140, after the indoor air of the photovoltaic air conditioner has been purified by the ozone generated by the ozone generator, the opening and closing of the fresh air duct and the exhaust duct are controlled in combination with the ozone concentration in the room where the photovoltaic air conditioner is located and the user activities in the room where the photovoltaic air conditioner is located, and at least one of the wind speed of the indoor fan of the photovoltaic air conditioner, the air outlet mode of the indoor unit of the photovoltaic air conditioner, the opening and closing of the ultraviolet generator, and the opening and closing of the activated carbon adsorption device are controlled to discharge the ozone in the room where the photovoltaic air conditioner is located, specifically to discharge the indoor ozone of the photovoltaic air conditioner to the outside through the exhaust duct.

[0068] The present invention proposes a photovoltaic air conditioner that utilizes a photovoltaic power generation system to electrolyze outdoor oxygen to produce ozone. This ozone is then transported indoors to purify the air, achieving efficient energy utilization while also regulating indoor air quality. The photovoltaic power generation system also self-consumes energy, achieving efficient energy utilization. Self-consumption means that the electricity generated by the system's photovoltaic power generation is entirely used for its own internal power consumption, achieving self-production and self-sales. Furthermore, the present invention controls the ozone generation rate based on the voltage of the photovoltaic power supply, regulating indoor ozone concentration and improving indoor air quality, addressing the lack of indoor ozone control in air conditioners in related solutions. The system also coordinates the oxygen concentration and temperature in indoor environments with long-term air conditioning use, achieving multi-dimensional air quality control and improving comfort. The ozone purification and ozone removal functions are both performed by the air conditioning system. When these functional modules are operating, the air conditioner's temperature control function is also in operation, affecting the indoor ambient temperature.

[0069] In some embodiments, the user activity status of the room where the photovoltaic air conditioner is located includes: whether the room where the photovoltaic air conditioner is located is occupied, or whether the room where the photovoltaic air conditioner is located is not occupied. The specific process of controlling the opening and closing of the fresh air duct and the exhaust duct, and controlling at least one of the wind speed of the indoor fan of the photovoltaic air conditioner, the air outlet pattern of the indoor unit of the photovoltaic air conditioner, the opening and closing of the ultraviolet generator, and the opening and closing of the activated carbon adsorption device in step S140 based on the ozone concentration in the room where the photovoltaic air conditioner is located and the user activity status in the room where the photovoltaic air conditioner is located, is described in the following exemplary embodiments.

[0070] The following combination Figure 2An embodiment flowchart of the method of the present application is shown, which further illustrates the specific process of controlling at least one of the opening and closing of the fresh air pipe and the exhaust air pipe, the air speed of the indoor fan, the air outlet mode of the indoor unit, the opening and closing of the ultraviolet generator, and the opening and closing of the activated carbon adsorption device in step S140. The specific process includes steps S210 to S250.

[0071] In step S210, if the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set first concentration threshold, the ozone removal function of the photovoltaic air conditioner is started. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner performing the air purification function also includes steps 3 and 4.

[0072] In step S220, under the ozone removal function of the photovoltaic air conditioner, if there is a user in the room where the photovoltaic air conditioner is located, the fresh air pipe and the exhaust air pipe are both opened, and the air speed of the indoor fan is controlled to be the preset maximum air speed. In addition, the area in the room where the photovoltaic air conditioner is located where the ozone concentration exceeds the set first concentration threshold is determined as the ozone area, and the air sweeping angle of the air sweeping device of the indoor unit is controlled to sweep the air towards the ozone area. The air sweeping device of the indoor unit includes the air deflector and the air sweeping blade, etc. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner performing the air purification function also includes the specific logic and implementation of the ozone removal function in step 3, which is as follows: step 31, when it is detected that the indoor ozone concentration exceeds the set first threshold, the air conditioner starts the ozone removal function. For example, an optical ozone sensor can be set, which can calculate the ozone concentration in the area by using the principle that ozone has an absorption effect on light of a specific wavelength. 0.5 PPM-1 PPM is the set first threshold, 1 PPM-1.3 PPM is the set second threshold, and 1.3 PPM and above is the set third threshold.

[0073] Step 32 includes steps 321 and 322.

[0074] In step 321, it is detected whether there is anyone in the room. When the presence of a human body is detected in the room, the air conditioner is switched to a strong wind block, the internal fan is at the maximum speed, and the fresh air duct and the exhaust duct are opened to make the indoor air flow quickly; at the same time, the photovoltaic air conditioner turns on the wind sweeping function, divides the room into multiple areas, and the ozone concentration in each area is different. The area with the highest ozone concentration is processed first, and the wind sweeping angle is aimed at the area with the highest ozone concentration so that the ozone detected in the area is carried by the air to the ventilation port, and the ozone is expelled to the outside.

[0075] In some embodiments, in step S220, the area where the ozone concentration in the room where the photovoltaic air conditioner is located exceeds the set first concentration threshold is determined as the ozone area, and the specific process of controlling the sweeping angle of the sweeping device of the indoor unit to sweep the air towards the ozone area is described in the following exemplary embodiment. Figure 3 The flowchart of an embodiment of the method of the present invention for controlling the sweeping angle of the sweeping device of the indoor unit to sweep the air toward the area where the ozone is located further illustrates the specific process of controlling the sweeping angle of the sweeping device of the indoor unit to sweep the air toward the area where the ozone is located in step S220, including: steps S310 to S320.

[0076] Step S310, based on the preset partitions in the room where the photovoltaic air conditioner is located, for the area where the ozone is located, determining the area with the maximum ozone concentration in the area where the ozone is located, and controlling the sweeping angle of the sweeping device of the indoor unit to sweep air towards the area with the maximum ozone concentration.

[0077] Step S320, after the first preset sweeping time corresponding to the area with the maximum ozone concentration, when it is determined that the ozone concentration in the area with the maximum ozone concentration is lower than the preset regional concentration threshold of the area with the maximum ozone concentration, it is determined that the sweeping of the area with the maximum ozone concentration is completed, and then the new area with the maximum ozone concentration in the area with the ozone is determined again for the area where the ozone is located, and the sweeping angle of the sweeping device of the indoor unit is controlled to sweep towards the new area with the maximum ozone concentration, and so on, until all areas in the area where the ozone is located are swept and the ozone concentration of each area in the area where the ozone is located is lower than the preset regional concentration threshold of each area; wherein the preset regional concentration threshold of each area is lower than the set first concentration threshold. Specifically, as Figure 7 As shown, the control logic of the photovoltaic air conditioner to perform the air purification function also includes:

[0078] In step 321, the room area is divided into multiple grid areas, and the ozone concentrations in these grid areas are detected. The ozone concentrations are further refined into multiple intervals. According to the different concentrations, the wind guide angle is positioned to the grid area with the highest concentration. The wind is continuously positioned to enhance the air flow in the area. The ozone will be carried by the air to other areas and ventilation ports, which will dilute the ozone concentration in the area. When a grid area completes the action, it is positioned to the next area and the action is repeated, so that the ozone in the room is ventilated outside, achieving the effect of removing indoor ozone. According to the relationship between the ozone concentrations in the area, the wind sweeping time will increase. The higher the regional concentration, the longer the positioning wind sweeping time is to ensure that the ozone in the area can be fully removed. After each action, some of the ozone in the room will be ventilated outside. The ozone concentration in the room is gradually decreasing, so the wind sweeping time is also gradually reduced. Figure 11 It is a schematic diagram of the structure of the indoor top view. Figure 11 The indoor bird's-eye view shown divides the room into multiple small grids. The grid with the highest concentration is determined, and the air conditioner will be positioned in this area for a certain period of time to speed up the indoor air flow and reduce the ozone concentration. Under the influence of the indoor air flow, some ozone will be pushed to the ventilation port, reducing the ozone concentration in the room.

[0079] In the solution of the present invention, the purpose of refining the threshold interval is to match the demand. If the ozone concentration in a certain area falls within a certain threshold range, then the duration of the sweeping air will reduce the ozone concentration in that area to zero. It will not be too long or too short, resulting in unreasonable ozone removal time, thereby achieving rational allocation of power resources and saving electricity. In step 321, the specific steps of refining the threshold interval include:

[0080] Step 3211: Set a plurality of refined threshold intervals Y1, Y2, Y3, .... Yn (n∈N, 0<n≤15) between the set first threshold and the set second threshold, where N is a positive integer.

[0081] Step 3212: When the ozone concentration in a certain area of ​​the room is detected to be within the first refined threshold interval Y1, the sweep angle is positioned at the area, and the sweep duration is 1 minute. When the ozone concentration in a certain area of ​​the room is detected to be within the second refined threshold interval Y2, the sweep angle is positioned at the area, and the sweep duration is 3 minutes. Similarly, when the ozone concentration in a certain area of ​​the room is detected to be within the refined threshold interval Yn, the sweep angle is positioned at the area, and the sweep duration is S. n The relationship with the number of refinement threshold intervals n is as follows:

[0082]

[0083] Step 3213: After completing the above steps, the wind deflector and blades are reset, and the wind speed and speed of the photovoltaic air conditioner are reset to the set wind speed and speed. After 30 seconds, the logic judgment and action instructions are re-entered. After completing the ozone removal action, the system is reset to the user-set wind speed and speed, and periodically monitors the ozone concentration to achieve closed-loop control. The speed and wind speed are consistent. Closed-loop control refers to periodically executing corresponding control actions based on changes in ozone concentration to achieve control of ozone concentration.

[0084] In the solution of the present invention, ozone is removed after air purification is completed, and the indoor ozone concentration is detected by a sensor and fed back to the processor to control the control system where the photovoltaic air conditioner is located, adjust the indoor air quality, and form a closed-loop control.

[0085] Step S230: Under the ozone removal function of the photovoltaic air conditioner, if there is no user in the room where the photovoltaic air conditioner is located, the area in the room where the photovoltaic air conditioner is located where the ozone concentration exceeds the set first concentration threshold is determined as the ozone area, the ultraviolet generator is controlled to turn on and sweep towards the ozone area to decompose the ozone into oxygen, the sweeping angle of the sweeping device of the indoor unit and the wind speed of the indoor fan are adjusted according to the ozone concentration in the room where the photovoltaic air conditioner is located, and the fresh air duct is controlled to be closed and the exhaust duct is controlled to be open. Specifically, Figure 7 As shown, the control logic of the photovoltaic air conditioner to perform the air purification function also includes: in step 3, the specific logic and implementation method of the ozone removal function are also as follows:

[0086] In step 322, when it is detected that there is no one in the room, an ultraviolet generator (such as a UV lamp) is used to sweep the area where ozone is detected to decompose the ozone into oxygen. At the same time, the windshield and speed R of the indoor unit of the photovoltaic air conditioner are adjusted according to the different ozone concentrations in the area, and the wind sweep is turned on to enhance the ventilation in the room, so that the undecomposed ozone is carried by the air to the ventilation port and discharged from the room.

[0087] In step 322, when no one is in the room, the UV lamp is activated to decompose indoor ozone, converting it into oxygen. Simultaneously, the air conditioner's speed and targeted sweeping assist in removing undecomposed ozone, effectively removing indoor ozone and increasing the ventilation rate for improved indoor air quality. Similarly, in areas with high ozone concentrations, the sweeping time and speed are increased to ensure rapid removal. The ozone concentration is divided into different concentration ranges to reduce power consumption and unnecessary energy consumption while still ensuring effective ozone removal.

[0088] In some embodiments, the specific process of adjusting the air sweeping angle of the air sweeping device of the indoor unit and the air speed of the indoor fan according to the ozone concentration of the room where the photovoltaic air conditioner is located in step S230 is described below.

[0089] The specific process of adjusting the air sweeping angle of the air sweeping device of the indoor unit and the air speed of the indoor fan according to the ozone concentration of the room where the photovoltaic air conditioner is located in step S230 is further described below in combination with Figure 4 The specific process of adjusting the air sweeping angle of the air sweeping device of the indoor unit and the air speed of the indoor fan according to the ozone concentration of the room where the photovoltaic air conditioner is located in step S230 is further described below in combination with

[0090] In step S410, based on the preset subzone in the room where the photovoltaic air conditioner is located, for the ozone area, if the ozone concentration threshold of any area in the ozone area is in the preset area concentration interval of the area, the air sweeping angle of the air sweeping device of the indoor unit is controlled to be aligned with the air sweeping of the area, and the air speed of the indoor fan is controlled to be the air speed corresponding to the preset area concentration interval of the area.

[0091] In step S420, after the second preset air sweeping time corresponding to the preset area concentration interval of the area, if the ozone concentration of the area is lower than the lower limit of the preset area concentration interval of the area, it is determined that the air sweeping of the area is completed, and then the air sweeping angle of the air sweeping device of the indoor unit is controlled to be aligned with the air sweeping of any area in the remaining area in the ozone area, and the air speed of the indoor fan is controlled to be the air speed corresponding to the preset area concentration interval of the area. The above process is repeated until all areas in the ozone area are swept and the ozone concentration of each area in the ozone area is lower than the lower limit of the preset area concentration interval of each area. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner for performing the air purification function further includes the following specific steps of refining the threshold interval in step 322.

[0092] In step 3221, a plurality of refined threshold intervals Y1, Y2, Y3... Yn (n∈N, 0

[0093] Step 3222: When it is detected that the ozone concentration in a certain area of ​​the room is in the first refined threshold interval Y1, the wind sweeping angle is positioned to the area, the speed R of the indoor fan is set to 850r / min, and the wind sweeping time is 1 minute. When it is detected that the ozone concentration in a certain area of ​​the room is in the second refined threshold interval Y2, the wind sweeping angle is positioned to the area, the speed R of the indoor fan is set to 875r / min, and the wind sweeping time is 3 minutes. Similarly, when it is detected that the ozone concentration in a certain area of ​​the room is in the refined threshold interval Yn, the wind sweeping angle is positioned to the area, and the wind sweeping time is S. n Relationship with the number of refined threshold intervals n, the speed of the indoor fan R n The relationship with the number of refinement threshold intervals n is as follows:

[0095] R n =850+25n n∈N, n≤15.

[0096] Figure 8 is the speed R of the indoor fan and the sweeping time S n The relationship table of the number of preset threshold intervals n of regional ozone concentration is Table 1, and the sweeping time S n Relationship with the number of refined threshold intervals n, the speed of the indoor fan R n The specific relationship with the number of refined threshold intervals n can be found in Figure 8 Examples are shown in Table 1.

[0097] Step 3223: When the ozone concentration in the room falls below the first preset threshold, after executing the above actions, the UV generator is turned off. One minute later, the wind deflector and blades of the photovoltaic air conditioner are reset, and the wind speed and speed of the photovoltaic air conditioner are reset to the set wind speed and set speed, fully discharging the indoor ozone and simultaneously updating the indoor air quality. After 30 seconds, the logic judgment is re-entered to execute the action command, and closed-loop control is also entered.

[0098] In the solution of the present invention, the ultraviolet lamp is a way to assist in air purification, not the main and only way, but the effect achieved by using this tool will be better; the ultraviolet lamp is used to photolyze indoor ozone, and its function is to remove the residual ozone sent into the room when purifying the air, thereby ensuring the safety of indoor air quality.

[0099] Step S240, after starting the ozone removal function of the photovoltaic air conditioner, if the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set second concentration threshold, the activated carbon adsorption device is controlled to be turned on, and the activated carbon adsorption device is controlled to be turned off after the ozone concentration in the room where the photovoltaic air conditioner is located is lower than the set second concentration threshold; wherein, if the adsorption capacity of the activated carbon adsorption device is lower than the set adsorption capacity, a reminder message is issued that the adsorption capacity of the activated carbon adsorption device is lower than the set adsorption capacity; the set second concentration threshold is greater than the set first concentration threshold. Specifically, if Figure 7 As shown, the control logic for the photovoltaic air conditioner to perform the air purification function also includes: Step 4, when it is detected that the indoor ozone concentration exceeds a set second threshold, the activated carbon adsorption device is activated, and then step 5 is performed. The set second threshold is greater than the set first threshold. Figure 9 This is a structural diagram of the activated carbon adsorption device sinking and moving out of the exhaust duct when the ozone concentration is lower than the set second threshold value. Figure 10 This is a schematic diagram of the structure in which the activated carbon adsorption device is pushed into the exhaust duct when the ozone concentration is higher than the set second threshold. Figure 9 and Figure 10 In the example shown, when ultraviolet rays cannot reduce ozone to a safe level indoors, an activated carbon adsorption device will be activated to assist in absorbing excess ozone. The activated carbon adsorption device is placed in the exhaust duct. When the indoor ozone concentration exceeds the set second threshold, the electric door in the exhaust duct opens, the lower piston is pushed out, and the activated carbon adsorption device is pushed into the exhaust duct. When the indoor ozone concentration falls below the set second threshold, the piston is retracted, the activated carbon adsorption device sinks and moves out of the exhaust duct, and the electric door closes. For details, please visit Figure 13 In the example shown, an activated carbon module is installed at the exhaust duct connection. It is screwed in by a piston motor for adsorption. When the activated carbon module is no longer needed, the motor rotates it out. When the activated carbon module reaches saturation, the photovoltaic air conditioner uses flashing lights and sound effects to alert the user that the activated carbon has reached saturation and that the module needs to be replaced or heated to release the adsorbed gas.

[0100] Step S250, after starting the activated carbon adsorption device, if the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set third concentration threshold, a reminder message is issued that the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set third concentration threshold; the set third concentration threshold is greater than the set second concentration threshold. Specifically, Figure 7As shown, the control logic for the photovoltaic air conditioner to perform the air purification function also includes the following steps: Step 5: When the indoor ozone concentration is detected to exceed a set third threshold, it is considered that the indoor ozone concentration is too high and poses a safety hazard. The photovoltaic air conditioner reminds the user to leave the room by issuing a warning signal, sound effects, flashing lights, transmitting a signal to a mobile phone app, etc. The set third threshold is greater than the set second threshold.

[0101] The solution of the present invention controls the opening and closing of the fresh air duct and the exhaust duct in combination with the ozone concentration in the room where the photovoltaic air conditioner is located and the user activities in the room where the photovoltaic air conditioner is located, and controls at least one of the wind speed of the indoor fan of the photovoltaic air conditioner, the air outlet mode of the indoor unit of the photovoltaic air conditioner, the opening and closing of the ultraviolet generator, and the opening and closing of the activated carbon adsorption device, thereby regulating the indoor ozone concentration, improving the indoor air quality, and enhancing comfort.

[0102] In some embodiments, the photovoltaic air conditioner further includes: an ozone storage, a purified air generator, a first switch, a second switch, a third switch, a fourth switch, a fifth switch and a sixth switch, the first switch being such as valve 1, the second switch being such as valve 2, the third switch being such as valve 3, the fourth switch being such as valve 4, the fifth switch being such as valve 5, and the sixth switch being such as valve 6; the second switch being arranged on the pipe between the exhaust duct and the room where the photovoltaic air conditioner is located; the first switch being arranged on the branch from the pipe between the second switch and the room where the photovoltaic air conditioner is located to the ozone storage; the third switch being arranged on the branch between the ozone storage and the purified air generator; the fourth switch being arranged on the pipe between the purified air generator and the fresh air duct; the fifth switch being arranged on the pipe from the pipe between the fourth switch and the fresh air duct to the room where the photovoltaic air conditioner is located; the sixth switch being arranged on the pipe between the purified air generator and the room where the photovoltaic air conditioner is located; wherein the first switch, the third switch, the fourth switch and the sixth switch are all normally closed switches, and the second switch and the fifth switch are both normally open switches. Accordingly, the control method of the photovoltaic air conditioner further includes: a control process for recycling ozone in the exhaust pipe. Figure 5 The flowchart of an embodiment of the control of recycling ozone in the exhaust pipe in the method of the present invention further illustrates the specific process of controlling recycling ozone in the exhaust pipe, including: step S510 to step S530.

[0103] Step S510, when it is necessary to discharge the ozone in the room where the photovoltaic air conditioner is located, control the first switch to be turned on, control the second switch to be turned off, and control the third switch, the fourth switch, the fifth switch and the sixth switch to maintain the current state, so as to store the ozone in the exhaust pipe in the ozone storage device.

[0104] Step S520: When the ozone concentration in the ozone storage is greater than the set storage ozone concentration threshold, the first switch, the third switch, and the fourth switch are all controlled to be turned on, and the opening degree of the first switch is controlled to be greater than the opening degree of the third switch, and the second switch, the fifth switch, and the sixth switch are all controlled to be closed, so that the ozone stored in the ozone storage is purified by the purified air generator.

[0105] In step S530, after the ozone stored in the ozone storage is purified by the purified air generator, the sixth switch is controlled to be turned on to deliver fresh air purified by the purified air generator into the room where the photovoltaic air conditioner is located. In the solution of the present invention, ozone can be recycled and reused to clean the fresh air. Figure 12 FIG. 1 is a schematic diagram of the structure of an embodiment of an ozone recovery system. Figure 12 As shown, the ozone discharged through the exhaust port of the exhaust duct can be collected in a sealed container (such as an ozone storage). When the ozone concentration in the ozone storage is greater than a certain concentration, the outdoor fresh air reacts with the ozone in the ozone storage in the purified air generator, and is then sent into the fresh air duct after purification. A valve 2 is provided on the pipe between the exhaust port of the exhaust duct and the room, a valve 1 is provided on the branch from the valve 2 and the room to the ozone storage, a valve 3 is provided on the branch between the ozone storage and the purified air generator, a valve 4 is provided on the pipe between the purified air generator and the fresh air duct, a valve 5 is provided on the pipe from the valve 4 and the fresh air duct to the room, and a valve 6 is provided on the pipe from the purified air generator away from the fresh air duct to the room.

[0106] Specifically, combined Figure 12The exhaust pipe is connected to a tee, and behind the tee are two stop valves 1 and 2 to control the direction of the exhaust air flow, one leading to the outside and the other to a sealed container. A pipeline is connected between the sealed container (i.e., the ozone storage) and the purified air generator to transport ozone to the generator to purify the fresh air. A one-way valve 3 is provided on the pipeline, which is normally closed; a valve 5 is provided on the pipeline between the valve 4 and the fresh air duct leading to the room, and a valve 6 is provided on the pipeline leading to the room on the side of the purified air generator away from the fresh air duct. A valve 5 is provided on the connecting pipeline between the fresh air duct and the indoor room, and a valve 6 is provided on the connecting pipeline between the purified air generator and the indoor room. Among them, valves 1, 3, 4, and 6 are normally closed. Normally, fresh air and exhaust air are replaced in the room through valves 2 and 5. When the room is discharging ozone, valve 1 opens and valve 2 closes, and the ozone is collected in the ozone storage. When ozone concentration exceeds a certain level, valves 1, 3, and 4 open, while valves 2, 5, and 6 close. Valve 1 opens wider than valve 3, reducing the ozone emission rate to a lower rate than the ozone collection rate. Fresh air from outside enters the purified air generator, reacting with ozone. After purification, valve 6 opens, sending the purified air into the room. This not only recycles ozone but also improves the air purification effect.

[0107] In the solution of the present invention, indoor air purification for photovoltaic air conditioners is achieved through ozone purification generated by an ozone generator and two-way ventilation to refresh the indoor air. Ozone is generated through photovoltaic electrolysis of oxygen, and the air supply speed and sweep time are controlled according to the ozone concentration. Ozone is generated by electrolysis of outdoor oxygen, and its safety is controlled to ensure air purification while protecting human health. The subsequent ozone removal control method can recycle the discharged ozone.

[0109] According to the embodiment of the present application, a control device of a photovoltaic air conditioner corresponding to the control method of the photovoltaic air conditioner is also provided. Referring to Figure 6 The power supply of the photovoltaic air conditioner includes a photovoltaic power supply system, and the photovoltaic power supply system has a photovoltaic panel; the photovoltaic air conditioner includes a fresh air pipe and an exhaust air pipe, an activated carbon adsorption device arranged at the exhaust air pipe, an ozone generator arranged at the outdoor side of the photovoltaic air conditioner, and an ultraviolet generator arranged at the indoor side of the photovoltaic air conditioner; the activated carbon adsorption device can adsorb ozone; the ozone generator can generate ozone by electrolyzing the oxygen in the outdoor air under the power supply of the photovoltaic power supply system, and then the ozone enters the indoor unit of the photovoltaic air conditioner or the room where the photovoltaic air conditioner is located to purify the indoor air of the photovoltaic air conditioner, and then is discharged to the outdoor from the exhaust air pipe; and the ultraviolet generator can decompose the ozone in the room where the photovoltaic air conditioner is located into oxygen. In the scheme of the present application, as shown in Figure 6 The control device of the photovoltaic air conditioner includes an acquisition unit 102 and a control unit 104.

[0110] The acquisition unit 102 is configured to acquire the output voltage of the photovoltaic panel, acquire the user activity in the room where the photovoltaic air conditioner is located, and acquire the ozone concentration in the room where the photovoltaic air conditioner is located when the air purification function of the photovoltaic air conditioner is turned on after the photovoltaic air conditioner is started. The specific functions and processes of the acquisition unit 102 are described in step S110.

[0111] The control unit 104 is configured to control the power supply mode of the photovoltaic power generation system and the rate at which the ozone generator generates ozone according to the output voltage of the photovoltaic panel when the ozone generator needs to be used to generate ozone, so as to use the ozone generator to generate ozone. The specific functions and processing of the control unit 104 are shown in step S120. In some embodiments, the control unit 104 controls the power supply mode of the photovoltaic power generation system and the rate at which the ozone generator generates ozone according to the output voltage of the photovoltaic panel, including at least one of the following control situations:

[0112] The first control scenario: the control unit 104 is further configured to control the power supply mode of the photovoltaic power generation system to the power supply mode of the photovoltaic panel if the output voltage of the photovoltaic panel is greater than a preset first voltage threshold and less than a preset second voltage threshold, and control the current power of the ozone generator to operate at a set power so that the current generation rate of the ozone generator is a preset generation rate. The output voltage of the photovoltaic panel is such as the power supply voltage UDC of the photovoltaic panel, and the preset first voltage threshold is such as U 过低保护 , the preset second voltage threshold is U 高压 .

[0113] The second control scenario: the control unit 104 is further configured to control the power supply mode of the photovoltaic power generation system to the power supply mode of the photovoltaic panel if the output voltage of the photovoltaic panel is greater than or equal to the preset second voltage threshold and less than the preset third voltage threshold, and control the current power of the ozone generator to be greater than the set power so that the current generation rate of the ozone generator is higher than the preset generation rate; wherein the preset third voltage threshold is U 过高 Protect.

[0114] The third control scenario: the control unit 104 is specifically further configured so that the photovoltaic power generation system also has a battery; if the output voltage of the photovoltaic panel is greater than or equal to a preset third voltage threshold, the compressor of the photovoltaic air conditioner is controlled to shut down for protection until the output voltage of the photovoltaic power generation system decreases to less than the preset third voltage threshold and then the compressor is restarted; the power supply mode of the photovoltaic power generation system is controlled to be a power supply mode in which the photovoltaic panel supplies power and the photovoltaic panel charges the battery, and the current power of the ozone generator is controlled to be greater than the set power so that the current generation rate of the ozone generator is higher than the preset generation rate.

[0115] The fourth control scenario: the control unit 104 is specifically further configured so that the photovoltaic power generation system also has a battery; if the output voltage of the photovoltaic panel is less than or equal to a preset first voltage threshold, the compressor of the photovoltaic air conditioner is controlled to shut down for protection until the output voltage of the photovoltaic power generation system increases to be greater than the preset first voltage threshold and then the compressor is restarted; the power supply mode of the photovoltaic power generation system is controlled to be the battery-powered power supply mode, and the current power of the ozone generator is controlled to be less than the set power so that the current generation rate of the ozone generator is lower than the preset generation rate.

[0116] The solution of the present invention is to set exhaust ducts and fresh air ducts for photovoltaic air conditioners, so as to update the quality of indoor air by ventilation. No new equipment is required and only the air conditioner itself can be used to achieve this, thus saving space and the object of action is indoor air. Figure 7 The control logic diagram for the photovoltaic air conditioner to perform air purification function. Figure 7 As shown in Figure 1, the control logic of the photovoltaic air conditioner to perform the air purification function includes:

[0117] Step 1: Start the photovoltaic air conditioner, and then proceed to step 2 to perform the air purification function.

[0118] Step 2: The photovoltaic air conditioner performs the air purification function, and then performs step 3, i.e., the ozone extraction function.

[0119] In step 2, the photovoltaic air conditioner performs the air purification function including: step 21 and step 22.

[0120] In step 21, in an outdoor ozone generator, the photovoltaic power provided by the photovoltaic power generation system electrolyzes oxygen in the outdoor air to produce ozone. The ozone generation rate is affected and controlled by the voltage of the photovoltaic power supply of the photovoltaic power generation system. In step 21, the specific process of controlling the ozone generation rate based on the voltage of the photovoltaic power supply includes: obtaining the current power supply voltage UDC of the photovoltaic panels in the photovoltaic power generation system in real time, comparing the power supply voltage UDC of the photovoltaic panels with different set values, determining the operating status of the batteries in the photovoltaic power generation system based on the comparison results, and determining the power supply source of the control system of the photovoltaic air conditioner. For details, please refer to the relevant descriptions of steps 211, 212, 213, and 214.

[0121] Step 211: Detect the voltage value of the photovoltaic panel's power supply voltage UDC to obtain the UDC voltage. 过低保护 <UDC voltage<U 高压 At this time, the power supply voltage UDC of the photovoltaic panel is within the normal range, indicating that the weather conditions are good, the photovoltaic panel can supply power normally, and the ozone generation rate is the set normal rate, that is, ozone is generated at the set normal rate.

[0122] Step 212: When U 高压 ≤UDC voltage<U 过高保护 When , it means that the photovoltaic panel has a larger power supply voltage at this time, which can provide sufficient energy for the control system of the photovoltaic air conditioner. At this time, the power of the outdoor ozone generator is increased, the ozone generation rate is accelerated, the supply ozone concentration is increased, and the effect of purifying the air indoors is better, and the time to complete the purification is less.

[0123] Step 213: When U 过高保护 If the voltage is less than or equal to the UDC voltage, the PV panel's supply voltage exceeds the requirements of the PV air conditioner's control system. The PV air conditioner's compressor will enter shutdown protection to prevent damage and ensure the reliability of the control system. Simultaneously, the maximum power point tracking (MPPT) controller in the photovoltaic power generation system directs the excess voltage to the outdoor ozone generator and battery, switching the battery to a charging state. Meanwhile, ozone generation continues at the rate set in step 212 to achieve optimal indoor purification. After the supply voltage is matched to the required voltage of the PV air conditioner's control system, the PV air conditioner's compressor restarts.

[0124] Step 214: When UDC voltage ≤ U 过低保护 When the temperature drops, it indicates poor weather conditions and a low photovoltaic panel supply. The PV air conditioner's compressor enters shutdown mode to prevent damage and ensure the reliability of the control system. Simultaneously, the battery switches to operation to meet the operating voltage requirements of the control system. The outdoor ozone generator also operates at low power, slowing ozone production and extending the time it takes to complete purification, ensuring sufficient battery power for all-weather operation. After the PV power generation system switches from photovoltaic power to battery power, the PV air conditioner's compressor starts.

[0125] In the solution of the present invention, the power of the control system where the photovoltaic air conditioner is located comes from an outdoor photovoltaic power generation system, which consumes the power by itself. The photovoltaic power generation system electrolyzes oxygen to produce ozone, which is sent indoors for air purification. According to the different power supply voltages, the power supply source is adjusted and the ozone generation rate is adjusted to ensure indoor comfort and energy saving requirements while ensuring the reliability of the control system where the photovoltaic air conditioner is located.

[0126] The control unit 104 is further configured to, in the case that the ozone generator has generated ozone, control the opening and closing of the fresh air pipe and the exhaust air pipe according to the user activity in the room where the photovoltaic air conditioner is located, and control the way in which the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner or the room where the photovoltaic air conditioner is located, so as to purify the indoor air of the photovoltaic air conditioner by using the ozone generated by the ozone generator, specifically, by using the ozone generated by the ozone generator to enter through the fresh air pipe to purify the indoor air of the photovoltaic air conditioner. The specific functions and processes of the control unit 104 are also described in step S130. In some embodiments, the user activity in the room where the photovoltaic air conditioner is located includes the case that the room where the photovoltaic air conditioner is located has a user, or the case that the room where the photovoltaic air conditioner is located has no user. The control unit 104 controls the opening and closing of the fresh air pipe and the exhaust air pipe according to the user activity in the room where the photovoltaic air conditioner is located, and controls the way in which the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner or the room where the photovoltaic air conditioner is located, including at least one of the following, that is, at least one control case in any of the following control cases:

[0127] The first control case: the control unit 104 is specifically further configured to, if the room where the photovoltaic air conditioner is located has a user, control the fresh air pipe and the exhaust air pipe to be both opened, so that the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner through the fresh air pipe and is then discharged from the exhaust air pipe without directly entering the room where the photovoltaic air conditioner is located.

[0128] The second control case: the control unit 104 is specifically further configured to, if the room where the photovoltaic air conditioner is located has no user, control the fresh air pipe to be opened and the exhaust air pipe to be closed, so that the ozone generated by the ozone generator enters the indoor unit of the photovoltaic air conditioner through the fresh air pipe and then directly enters the room where the photovoltaic air conditioner is located, and after a period of time, the exhaust air pipe is controlled to be opened, so that the ozone and its reactants in the room where the air conditioner is located are discharged outdoors. Specifically, as shown in FIG. 22, the control logic of the photovoltaic air conditioner for performing the air purification function further includes: step 22, after generating ozone outdoors, sending the ozone generated outdoors into the room for air purification, and performing classified control according to the human activity in the room. Figure 7

[0129] In step 22, in the case that there is a person in the room, the fresh air pipe and the exhaust air pipe of the photovoltaic air conditioner are opened, so that the ozone generated outdoors enters through the fresh air pipe and is then discharged through the exhaust air pipe. In this way, the ozone does not enter the room, and the indoor air is updated by the bidirectional ventilation of the fresh air pipe and the exhaust air pipe.

[0130] ​In step 22, in the case that there is no one in the room, ozone is sent into the room, after the ozone purifies the indoor air, the fresh air pipeline and the exhaust pipeline are opened, the ozone and related reactants are discharged from the room, and fresh air is sent into the room, so that better purification effect is achieved.

[0131] The scheme of the present application provides a control scheme of a photovoltaic air conditioner, ozone is used to purify air, a fresh air pipeline and an exhaust pipeline and other system structures are added, and air conditioner function operation logic is adjusted, so that indoor air quality is improved, and the shortage of air conditioner ozone adjustment function in related schemes is filled.

[0132] The control unit 104 is further configured to, after the indoor air of the photovoltaic air conditioner has been purified by using the ozone generated by the ozone generator, control at least one of opening and closing of the fresh air pipe and the exhaust pipe, and controlling at least one of a wind speed of an indoor fan of the photovoltaic air conditioner, an air outlet mode of an indoor unit of the photovoltaic air conditioner, opening and closing of the ultraviolet generator, and opening and closing of the activated carbon adsorption device, according to the ozone concentration of the room where the photovoltaic air conditioner is located and the user activity situation of the room where the photovoltaic air conditioner is located, so as to discharge ozone from the room where the photovoltaic air conditioner is located, specifically to discharge indoor ozone of the photovoltaic air conditioner to the outside through the exhaust pipe. The specific functions and processes of the control unit 104 are also described in step S140.

[0133] The scheme of the present application provides a photovoltaic air conditioner, which uses a photovoltaic power generation system to electrolyze outdoor oxygen to generate ozone, and uses part of the ozone to purify indoor air, so as to realize efficient use of energy and adjust indoor air quality; the photovoltaic power generation system is self-consumed, so as to realize efficient use of energy. In the scheme of the present application, the generation rate of ozone is controlled according to the voltage of photovoltaic power supply, so as to control indoor ozone concentration and improve indoor air quality, thereby solving the problem of lack of indoor ozone control in related schemes; the oxygen concentration and temperature of the indoor environment of the room where the air conditioner is used for a long time are cooperatively adjusted, so as to realize multi-dimensional air quality adjustment and improve comfort.

[0134] In some embodiments, the user activity situation of the room where the photovoltaic air conditioner is located includes a case that there is a user in the room where the photovoltaic air conditioner is located, or a case that there is no user in the room where the photovoltaic air conditioner is located. The control unit 104 controls at least one of opening and closing of the fresh air pipe and the exhaust pipe, and controls at least one of the wind speed of the indoor fan of the photovoltaic air conditioner, the air outlet mode of the indoor unit of the photovoltaic air conditioner, the opening and closing of the ultraviolet generator, and the opening and closing of the activated carbon adsorption device, according to the ozone concentration of the room where the photovoltaic air conditioner is located and the user activity situation of the room where the photovoltaic air conditioner is located, including:

[0135] The control unit 104 is specifically further configured to start the ozone removal function of the photovoltaic air conditioner when the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set first concentration threshold. The specific functions and processes of the control unit 104 are also described in step S210. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner for executing the air purification function further includes steps 3 and 4.

[0136] The control unit 104 is specifically further configured to, under the ozone removal function of the photovoltaic air conditioner, if there is a user in the room where the photovoltaic air conditioner is located, control the fresh air pipe and the exhaust air pipe to be opened, control the wind speed of the indoor fan to be the preset maximum wind speed, determine the area in the room where the photovoltaic air conditioner is located where the ozone concentration exceeds the set first concentration threshold as the ozone area, and control the sweeping angle of the sweeping device of the indoor unit to be aligned with the ozone area for sweeping. The sweeping device of the indoor unit includes the deflector and the sweeping blade, etc. The specific functions and processes of the control unit 104 are also described in step S220. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner for executing the air purification function further includes steps 3 and 4.

[0137] Step 32 includes steps 321 and 322.

[0138] In step 321, it is detected whether there is a human body in the room. When it is detected that there is a human body in the room, the air conditioner is switched to the strong wind resistance, the maximum rotating speed of the indoor fan, the fresh air pipe and the exhaust air pipe are opened, so that the indoor air flows rapidly. At the same time, the photovoltaic air conditioner opens the sweeping function, divides the room into multiple areas, the ozone concentrations in the areas are different, the area with the largest ozone concentration is preferentially processed, the sweeping angle is aligned with the area with the largest ozone concentration, so that the ozone detected in the area is carried by the air to the air outlet, and the ozone is driven to the outdoor.

[0139] In some embodiments, the control unit 104 determines the area in the room where the photovoltaic air conditioner is located where the ozone concentration exceeds the set first concentration threshold as the ozone area, and controls the sweeping angle of the sweeping device of the indoor unit to be aligned with the ozone area for sweeping, including:

[0140] The control unit 104 is further configured to determine, based on the preset partitions within the room where the photovoltaic air conditioner is located, the area with the highest ozone concentration within the ozone area, and control the air sweeping device of the indoor unit to sweep air at an angle directed toward the area with the highest ozone concentration. The specific functions and processing of the control unit 104 are further described in step S310.

[0141] The control unit 104 is further configured to, after a first preset sweeping time corresponding to the area with the maximum ozone concentration, determine that the sweeping of the area with the maximum ozone concentration is complete if it is determined that the ozone concentration in the area with the maximum ozone concentration is lower than a preset regional concentration threshold for the area with the maximum ozone concentration, then re-determine a new area with the maximum ozone concentration in the area with the ozone, and control the sweeping angle of the sweeping device of the indoor unit to sweep the area with the new maximum ozone concentration, and so on, until all areas in the area with the ozone concentration are swept and the ozone concentration in each area in the area with the ozone concentration is lower than the preset regional concentration threshold for each area; wherein the preset regional concentration threshold for each area is lower than the set first concentration threshold. The specific functions and processing of the control unit 104 are further described in step S320.

[0142] Specifically, if Figure 7 As shown, the control logic of the photovoltaic air conditioner to perform the air purification function also includes:

[0143] In step 321, the room area is divided into multiple grid areas, and the ozone concentrations in these grid areas are detected. The ozone concentrations are further refined into multiple intervals. According to the different concentrations, the wind guide angle is positioned to the grid area with the highest concentration. The wind is continuously positioned to enhance the air flow in the area. The ozone will be carried by the air to other areas and ventilation ports, which will dilute the ozone concentration in the area. When a grid area completes the action, it is positioned to the next area and the action is repeated, so that the ozone in the room is ventilated outside, achieving the effect of removing indoor ozone. According to the relationship between the ozone concentrations in the area, the wind sweeping time will increase. The higher the regional concentration, the longer the positioning wind sweeping time is to ensure that the ozone in the area can be fully removed. After each action, some of the ozone in the room will be ventilated outside. The ozone concentration in the room is gradually decreasing, so the wind sweeping time is also gradually reduced.

[0144] Figure 11 It is a schematic diagram of the structure of the indoor top view. Figure 11The indoor overhead view shown divides the room into multiple small grids, determines the grid with the maximum concentration, and positions the air conditioning air sweeping to the area, blows for a certain time, accelerates the indoor air flow, and reduces the ozone concentration. Affected by the indoor air flow, part of the ozone will be pushed to the air outlet, reducing the ozone concentration in the room. In the scheme of the application, the purpose of refining the threshold interval is to match the needs. The ozone concentration in a certain area is located in which threshold range, and then the blowing time of the air sweeping can reduce the ozone concentration in the area to 0. It will not be too long or too short to cause unreasonable removal of ozone time, thereby realizing the rational allocation of power resources and saving power. In step 321, the specific steps of refining the threshold interval include:

[0145] Step 3211, a plurality of refined threshold intervals Y1, Y2, Y3... Yn (n∈N, 0

[0146] Step 3212, when detecting that the ozone concentration in a certain area of the room is in the first refined threshold interval Y1, the air sweeping angle is positioned to the area, and the air sweeping time is 1 minute. When detecting that the ozone concentration in a certain area of the room is in the second refined threshold interval Y2, the air sweeping angle is positioned to the area, and the air sweeping time is 3 minutes. In this way, when detecting that the ozone concentration in a certain area of the room is in the refined threshold interval Yn, the air sweeping angle is positioned to the area, and the air sweeping time is S n The relationship with the number n of refined threshold intervals is as follows:

[0147]

[0148] Step 3213, after the above actions are performed, the deflector and the deflector blade are reset, the air baffle and the rotation speed of the photovoltaic air conditioner are reset to the set air baffle and the set rotation speed, and after 30s, the logic judgment execution action instruction is re-entered. After the ozone removal action is performed, it is reset to the user set air baffle and set rotation speed for operation, periodic detection of ozone concentration is performed, and closed loop control is realized.

[0149] In the scheme of the application, after air purification is completed, ozone is removed, the indoor ozone concentration is detected by the sensor, and the control system of the photovoltaic air conditioner is controlled after feedback to the processor, the indoor air quality is adjusted, and closed loop control is formed.

[0150] The control unit 104 is also specifically configured to, under the ozone removal function of the photovoltaic air conditioner, if there is no user in the room where the photovoltaic air conditioner is located, determine the area in the room where the photovoltaic air conditioner is located where the ozone concentration exceeds the set first concentration threshold as the ozone area, control the ultraviolet generator to turn on and sweep towards the ozone area to decompose the ozone into oxygen, adjust the sweeping angle of the sweeping device of the indoor unit and the wind speed of the indoor fan according to the ozone concentration in the room where the photovoltaic air conditioner is located, and control the fresh air duct to be closed and the exhaust duct to be opened. The specific functions and processing of the control unit 104 can also be found in step S230. Specifically, if Figure 7 As shown, the control logic of the photovoltaic air conditioner to perform the air purification function also includes: in step 3, the specific logic and implementation method of the ozone removal function are also as follows:

[0151] In step 322, when it is detected that there is no one in the room, an ultraviolet generator (such as a UV lamp) is used to sweep the area where ozone is detected to decompose the ozone into oxygen. At the same time, the windshield and speed R of the indoor unit of the photovoltaic air conditioner are adjusted according to the different ozone concentrations in the area, and the wind sweep is turned on to enhance the ventilation in the room, so that the undecomposed ozone is carried by the air to the ventilation port and discharged from the room.

[0152] In step 322, when no one is in the room, the UV lamp is activated to decompose indoor ozone, converting it into oxygen. Simultaneously, the air conditioner's speed and targeted sweeping assist in removing undecomposed ozone, effectively removing indoor ozone and increasing the ventilation rate for improved indoor air quality. Similarly, in areas with high ozone concentrations, the sweeping time and speed are increased to ensure rapid removal. The ozone concentration is divided into different concentration ranges to reduce power consumption and unnecessary energy consumption while still ensuring effective ozone removal.

[0153] In some embodiments, the control unit 104 adjusts the sweeping angle of the sweeping device of the indoor unit and the wind speed of the indoor fan according to the ozone concentration in the room where the photovoltaic air conditioner is located, including:

[0154] The control unit 104 is further configured to, based on the preset partitions within the room where the photovoltaic air conditioner is located, determine, for the ozone location area, that the ozone concentration threshold of any area within the ozone location area is within the preset regional concentration range for that area, control the sweeping angle of the sweeping device of the indoor unit to sweep air toward the area, and control the wind speed of the indoor fan to a wind speed corresponding to the preset regional concentration range for that area. The specific functions and processing of the control unit 104 are further described in step S410.

[0155] The control unit 104 is also specifically configured to determine that the sweeping of any area is completed after the second preset sweeping time corresponding to the preset regional concentration interval of any area, when it is determined that the ozone concentration in any area is lower than the lower limit of the preset regional concentration interval of any area, and then redetermine that the ozone concentration threshold of any area in the remaining area of ​​the ozone area is within the preset regional concentration interval of any area of ​​the remaining area, control the sweeping angle of the sweeping device of the indoor unit to sweep the air to any area of ​​the remaining area, and control the wind speed of the indoor fan to be the wind speed corresponding to the preset regional concentration interval of any area of ​​the remaining area, and so on, until all areas in the ozone area are swept and the ozone concentration of each area in the ozone area is lower than the lower limit of the preset regional concentration interval of each area; wherein the lower limit of the preset regional concentration interval of each area is lower than the set first concentration threshold. The specific functions and processing of the control unit 104 can also be found in step S420. Specifically, if Figure 7 As shown, the control logic of the photovoltaic air conditioner performing the air purification function further includes: in step 322, the specific steps of refining the threshold interval include:

[0156] Step 3221: Set a plurality of refined threshold intervals Y1, Y2, Y3, .... Yn (n∈N, 0<n≤15) between the set first threshold and the set second threshold, where N is a positive integer.

[0157] Step 3222: When it is detected that the ozone concentration in a certain area of ​​the room is in the first refined threshold interval Y1, the wind sweeping angle is positioned to the area, the speed R of the indoor fan is set to 850r / min, and the wind sweeping time is 1 minute. When it is detected that the ozone concentration in a certain area of ​​the room is in the second refined threshold interval Y2, the wind sweeping angle is positioned to the area, the speed R of the indoor fan is set to 875r / min, and the wind sweeping time is 3 minutes. Similarly, when it is detected that the ozone concentration in a certain area of ​​the room is in the refined threshold interval Yn, the wind sweeping angle is positioned to the area, and the wind sweeping time is S. n Relationship with the number of refined threshold intervals n, the speed of the indoor fan R n The relationship with the number of refinement threshold intervals n is as follows:

[0158]

[0159] R n =850+25n n∈N, n≤15.

[0160] Figure 8 is the speed R of the indoor fan and the sweeping time S n The relationship table of the number of preset threshold intervals n of regional ozone concentration is Table 1, and the sweeping time S nThe number of refined threshold intervals n is related to the rotation speed R of the indoor fan n The number of refined threshold intervals n is related to the rotation speed R of the indoor fan Figure 8 The example shown in Table 1.

[0161] Step 3223, when the ozone concentration in the room is lower than the first preset threshold, after the above actions are performed, the ultraviolet generator is turned off, and 1 min later the baffle and the blade of the photovoltaic air conditioner are reset, and the damper and the rotation speed of the photovoltaic air conditioner are reset to the set damper and the set rotation speed, so as to fully discharge the indoor ozone and update the indoor air quality. Then 30s later, re-enter the logical judgment execution action instruction, and enter the closed loop control.

[0162] In the scheme of the application, the ultraviolet lamp is an auxiliary way of air purification, and is not the main and only way, but the effect achieved by using this tool will be better; the ultraviolet lamp is used for photolysis of indoor ozone, and the role is to remove the residual ozone sent into the room during air purification, so as to ensure the safety of indoor air quality.

[0163] The control unit 104 is specifically configured to, after starting the ozone removal function of the photovoltaic air conditioner, if the ozone concentration of the room where the photovoltaic air conditioner is located is higher than the set second concentration threshold, control the activated carbon adsorption device to be turned on until the ozone concentration of the room where the photovoltaic air conditioner is located is lower than the set second concentration threshold, and then control the activated carbon adsorption device to be turned off; if the adsorption capacity of the activated carbon adsorption device is lower than the set adsorption capacity, a reminder message that the adsorption capacity of the activated carbon adsorption device is lower than the set adsorption capacity is initiated; the set second concentration threshold is greater than the set first concentration threshold. The specific functions and processing of the control unit 104 also refer to step S240. Specifically, as shown in Figure 7 The control logic of the photovoltaic air conditioner for performing the air purification function also includes: step 4, when it is detected that the indoor ozone concentration exceeds the set second threshold, the activated carbon adsorption device is enabled, and then step 5 is performed. The set second threshold is greater than the set first threshold.

[0164] Figure 9 For the structure diagram of the activated carbon adsorption device sinking out of the exhaust duct when the ozone concentration is lower than the set second threshold, Figure 10 For the structure diagram of the activated carbon adsorption device being pushed into the exhaust duct when the ozone concentration is higher than the set second threshold. Combined with Figure 9 and Figure 10The example shown, when the ultraviolet rays in the room cannot reduce the ozone to a safe level, the activated carbon adsorption device will be activated to assist in adsorbing excess ozone, and the activated carbon adsorption device is placed in the exhaust duct. When the ozone concentration in the room exceeds the set second threshold value, the electric door in the exhaust duct opens, the lower piston pushes out, and the activated carbon adsorption device is pushed into the exhaust duct. When the ozone concentration in the room is lower than the set second threshold value, the piston is retracted, and the activated carbon adsorption device is lowered and moved out of the exhaust duct. The electric door is closed. When it is detected that the activated carbon adsorption device is adsorbed to a saturated state, the photovoltaic air conditioner reminds the user that the activated carbon has reached saturation and needs to replace the activated carbon adsorption device or heat the activated carbon adsorption device to release the adsorbed gas through light flashing, sound effects, etc.

[0165] The control unit 104 is specifically further configured to, after starting the activated carbon adsorption device, if the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set third concentration threshold, initiate a reminder message that the ozone concentration in the room where the photovoltaic air conditioner is located is higher than the set third concentration threshold. The set third concentration threshold is greater than the set second concentration threshold. The specific functions and processes of the control unit 104 also refer to step S250. Specifically, as shown in the figure, the control logic of the photovoltaic air conditioner for executing the air purification function also includes: step 5, when it is detected that the indoor ozone concentration exceeds the set third threshold value, at this time it can be considered that the indoor ozone concentration is too high, and there is a safety hazard. The photovoltaic air conditioner reminds the user to leave the room by sending a warning signal, sound effect, light flashing, signal transmission to the mobile phone APP, etc. Wherein, the set third threshold value is greater than the set second threshold value. Figure 7

[0166] The scheme of the present application combines the ozone concentration in the room where the photovoltaic air conditioner is located and the user activity in the room where the photovoltaic air conditioner is located. The opening and closing of the fresh air pipe and the exhaust pipe are controlled, and at least one of the wind speed of the indoor fan of the photovoltaic air conditioner, the air outlet mode of the indoor unit of the photovoltaic air conditioner, the opening and closing of the ultraviolet ray generator, and the opening and closing of the activated carbon adsorption device is controlled. Regulate the indoor ozone concentration, improve the indoor air quality, and improve the comfort.

[0167] ​In some embodiments, the photovoltaic air conditioner further comprises: an ozone storage device, a purified air generator, a first switch, a second switch, a third switch, a fourth switch, a fifth switch and a sixth switch, the first switch being a valve 1, the second switch being a valve 2, the third switch being a valve 3, the fourth switch being a valve 4, the fifth switch being a valve 5, and the sixth switch being a valve 6; the second switch is arranged on a pipeline between the exhaust pipe and a room where the photovoltaic air conditioner is located; the first switch is arranged on a branch of the pipeline between the second switch and the room where the photovoltaic air conditioner is located, and the branch leads to the ozone storage device; the third switch is arranged on a branch between the ozone storage device and the purified air generator; the fourth switch is arranged on the pipeline between the purified air generator and the fresh air pipe; the fifth switch is arranged on the pipeline between the fourth switch and the fresh air pipe, and the pipeline leads to the room where the photovoltaic air conditioner is located; the sixth switch is arranged on the pipeline between the purified air generator and the room where the photovoltaic air conditioner is located; wherein the first switch, the third switch, the fourth switch and the sixth switch are all normally closed switches, and the second switch and the fifth switch are both normally open switches. Correspondingly, the control method of the photovoltaic air conditioner further comprises: a control process for recycling ozone in the exhaust pipe, which is specifically as follows.

[0168] The control unit 104 is further configured to, in the case that it is necessary to discharge ozone from the room where the photovoltaic air conditioner is located, control the first switch to be opened, control the second switch to be closed, and control the third switch, the fourth switch, the fifth switch and the sixth switch to keep the current state, so as to store the ozone in the exhaust pipe in the ozone storage device. The specific functions and processes of the control unit 104 are also described in step S510.

[0169] The control unit 104 is further configured to, in the case that the ozone concentration in the ozone storage device is greater than a set storage ozone concentration threshold, control the first switch, the third switch and the fourth switch to be opened, control the opening degree of the first switch to be greater than the opening degree of the third switch, and control the second switch, the fifth switch and the sixth switch to be closed, so as to make the ozone stored in the ozone storage device purified by the purified air generator. The specific functions and processes of the control unit 104 are also described in step S520.

[0170] The control unit 104 is further configured to, after the ozone stored in the ozone storage device is purified by the purified air generator, control the sixth switch to be opened, so as to send the fresh air after the purified air generator is purified into the room where the photovoltaic air conditioner is located. The specific functions and processes of the control unit 104 are also described in step S530.

[0171] In the solution of the present invention, ozone can be recycled and used to clean fresh air. Figure 12 FIG. 1 is a schematic diagram of the structure of an embodiment of an ozone recovery system. Figure 12 As shown, the ozone discharged through the exhaust port of the exhaust duct can be collected in a sealed container (such as an ozone storage). When the ozone concentration in the ozone storage is greater than a certain concentration, the outdoor fresh air reacts with the ozone in the ozone storage in the purified air generator, and is then sent into the fresh air duct after purification. A valve 2 is provided on the pipe between the exhaust port of the exhaust duct and the room, a valve 1 is provided on the branch from the valve 2 and the room to the ozone storage, a valve 3 is provided on the branch between the ozone storage and the purified air generator, a valve 4 is provided on the pipe between the purified air generator and the fresh air duct, a valve 5 is provided on the pipe from the valve 4 and the fresh air duct to the room, and a valve 6 is provided on the pipe from the purified air generator away from the fresh air duct to the room.

[0172] Among them, valves 1, 3, 4, and 6 are normally closed. Normally, fresh air and exhaust air are exchanged for air in the room through valves 2 and 5. When ozone is discharged from the room, valve 1 opens and valve 2 closes, collecting the ozone in the ozone storage. When the ozone concentration exceeds a certain level, valves 1, 3, and 4 open, while valves 2, 5, and 6 close. The opening of valve 1 is greater than that of valve 3, so that the ozone emission rate is lower than the ozone collection rate. At this time, the outdoor fresh air will enter the purified air generator and react with the ozone. After purification, valve 6 opens, sending the purified fresh air into the room, which not only recycles the ozone but also improves the room air purification effect.

Ozone is generated through photovoltaic electrolysis of oxygen, and the air supply speed and sweep time are controlled according to the ozone concentration. Ozone is generated by electrolysis of outdoor oxygen, and its safety is controlled to ensure air purification while protecting human health. The subsequent ozone removal control method can recycle the discharged ozone.
