[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] According to an embodiment of the present invention, a heat dissipation structure is provided, including: a battery compartment 1, in which an energy storage battery 11 is arranged; a compression compartment 2, in which a compressor structure 21 is arranged; a heat dissipation compartment 3, in which a heat dissipation component 31 is arranged; the heat dissipation compartment 3 is connected to the battery compartment 1; a photovoltaic component 4, which is located outside the battery compartment 1, the compression compartment 2 and the heat dissipation compartment 3; a control module, which controls the compression compartment 2 to exchange heat with the battery compartment 1 according to the working state of the energy storage battery 11; the control module controls the heat dissipation compartment 3 to exchange heat with the battery compartment 1 according to the working state of the energy storage battery 11.

[0022] Specifically, in some embodiments, the photovoltaic assembly 4 is located above the casing where the battery compartment 1 , the compression compartment 2 , and the heat dissipation compartment 3 are located, or is connected to the outside of the casing.

[0023] In some embodiments, the photovoltaic assembly 4 is used to absorb solar energy to charge a battery or feed the converted electric energy into a grid.

[0024] Specifically, after the photovoltaic module 4 absorbs external energy, it stores the energy in the energy storage battery 11. The battery compartment containing the energy storage battery 11 is connected to the heat dissipation compartment 3 and the compression compartment. The heat dissipation compartment 3 is provided with a heat dissipation component 31 for heat dissipation, and the compression compartment 2 is provided with a compressor structure, which generates heat when working. According to the working state of the energy storage battery 11, the battery compartment 1 is connected with the above two compartments to achieve the effect of heat dissipation or heating of the energy storage battery.

[0025] By adopting the above-mentioned settings, the role of each component compartment can be fully utilized and coordinated control can be achieved, which can not only solve the operation and startup problems of the energy storage batteries inside the equipment, but also make the heat distribution inside the entire equipment uniform, improve the reliability of the product, and solve the technical problem in the related technology that the performance of the battery of the solar storage air conditioner is affected by temperature.

[0026] See also Figure 2 In the heat dissipation structure of this embodiment, the heat dissipation component 31 is a fan arranged in the heat dissipation bin 3, and the heat dissipation structure also includes: a first channel (10), the first channel (10) connects the heat dissipation bin 3 with the compression bin 2; and an air valve 6, the air valve 6 is used to open or close the first channel (10).

[0027] With the above arrangement, the fan blows air into the battery compartment 1 to dissipate heat for the energy storage battery 11, thereby achieving the effect of cooling the energy storage battery 11. By setting the air valve, the heat exchange process of the energy storage battery 11 can be conveniently started or terminated.

[0028] See also Figure 1 In the heat dissipation structure of the present embodiment, the heat dissipation structure further includes: a second channel (20), the second channel (20) connecting the compression chamber 2 and the battery chamber 1; and / or a heat collecting component 7, the heat collecting component 7 is used to absorb the heat in the compression chamber 2 to transfer the heat in the compression chamber 2 to the battery chamber 1.

[0029] With the above arrangement, the energy storage battery 11 is heated by blowing the hot air flow in the compression chamber 2 into the battery chamber 1. The heating rate of the energy storage battery 11 can be increased by providing the heat collecting component 7.

[0030] See also Figure 1 In the heat dissipation structure of this embodiment, the heat dissipation structure further includes: a ventilation channel 12 provided on the battery compartment 1, and the ventilation channel 12 connects the battery compartment 1 to the outside of the battery compartment 1. In this way, the airflow inside the heat dissipation structure is blown to the outside, thereby achieving overall heat dissipation and ensuring normal operation of the system.

[0031] In the heat dissipation structure of this embodiment, see Figure 1 , Figure 2 The compression chamber 2 is located on one side of the heat dissipation chamber 3, and the battery chamber 1 is located on the side of the compression chamber 2 away from the heat dissipation chamber 3. In this way, when the fan blows airflow, all the heat in the battery chamber 1 and the compression chamber 2 can be blown away, thereby achieving overall heat dissipation and ensuring normal operation of the system.

[0032] See also Figure 1 , Figure 2 In the heat dissipation structure of this embodiment, the heat dissipation structure also includes a controller compartment 8, and the controller compartment 8 is located on one side of the heat dissipation compartment 3, and the controller compartment 8 is located above the compression compartment 2 and the battery compartment 1.

[0033] With the above arrangement, a control panel is provided on the controller compartment 8, thereby facilitating operation by the staff.

[0034] In the heat dissipation structure of this embodiment, see Figure 2 The photovoltaic assembly 4 includes: a photovoltaic panel 41, which is located above the heat dissipation compartment 3 and the controller compartment 8; a bracket 42, one end of the bracket 42 is connected to the heat dissipation compartment 3 and / or the controller compartment 8, and the other end of the bracket 42 is connected to the photovoltaic panel 41.

[0035] In this way, the warehouse body will not block the photovoltaic components 4, ensuring the normal operation of each module.

[0036] The air conditioner of this embodiment includes a heat dissipation structure, and the heat dissipation structure is the heat dissipation structure mentioned above.

[0037] In the air conditioner of this embodiment, the heat dissipation compartment 3, the compression compartment 2, and the battery compartment 1 are jointly controlled to form an active heat dissipation system. Different heat dissipation modes and air ducts are switched according to the cooling and heating modes of the light storage air conditioner. The air conditioner of this embodiment gives full play to the role of each component compartment and coordinates the control, which can not only solve the operation and startup problems of the energy storage battery inside the equipment, but also make the heat distribution inside the entire equipment uniform, improve the reliability of the product, and extend the service life.

[0038] The control method of this embodiment is applicable to the above-mentioned heat dissipation structure, and the control method includes: judging whether the energy storage battery 11 in the battery compartment 1 needs to be heated up or cooled down; when the energy storage battery 11 needs to be heated up, the compression compartment 2 exchanges heat with the battery compartment 1; when the energy storage battery 11 needs to be cooled down, the heat dissipation compartment 3 exchanges heat with the battery compartment 1.

[0039] By adopting the above method, the heat dissipation chamber 3, the compression chamber 2, and the battery chamber 1 are jointly controlled to form an active heat dissipation system. Different heat dissipation modes and air ducts are switched according to the cooling and heating modes of the light storage air conditioner. The air conditioner of this embodiment gives full play to the role of each component chamber and coordinates the control, which can not only solve the operation and startup problems of the energy storage battery inside the equipment, but also make the heat distribution inside the entire equipment uniform, improve the reliability of the product, and extend the service life.

[0040] In the control method of this embodiment, see Figures 3 to 6 The method for determining whether the energy storage battery 11 in the battery compartment 1 needs to be heated up or cooled down includes: when the air conditioner needs to be heated, determining that the energy storage battery 11 needs to be heated up; when the air conditioner needs to be cooled, determining that the energy storage battery 11 needs to be cooled down.

[0041] Specifically, the air conditioner operates for heating in winter, and the low temperature in winter will cause the energy storage battery to not work normally. The energy storage battery can be heated by utilizing the waste heat from the operation of the compressor so that it can operate normally.

[0042] The air conditioner runs for cooling in the summer, and the temperature is high in the summer. The energy storage battery will also generate heat when working. Therefore, in order to prevent the inside of the product from overheating, it is usually necessary to dissipate heat for the energy storage battery.

[0043] See also Figures 3 to 6 In the control method of this embodiment, the method for exchanging heat between the compression chamber 2 and the battery chamber 1 includes: connecting the compression chamber 2 with the battery chamber 1 so that the fluid in the compression chamber 2 enters the battery chamber 1.

[0044] Specifically, by closing the ventilation passages of the heat dissipation chamber 3 and the compression chamber 2, the waste heat generated by the operation of the compressor does not escape from the air dissipation chamber 3, and the waste heat is used to heat the energy storage battery 11. Thus, the temperature of the energy storage battery 11 is quickly increased.

[0045] In the control method of this embodiment, the method for exchanging heat between the heat dissipation compartment 3 and the battery compartment 1 includes: connecting the heat dissipation compartment 3 with the battery compartment 1 so that the fluid in the heat dissipation compartment 3 enters the battery compartment 1 .

[0046] Embodiment 1: In the heat dissipation structure of this embodiment, the schematic diagram of the photovoltaic storage air conditioning device after the photovoltaic module, air conditioning and energy storage are integrated is shown in Figure 2 The equipment is provided with a heat dissipation compartment 3, a controller compartment 8, a battery compartment 1, a compression compartment 2, a top plate, a front panel, an interface panel, and a photovoltaic module 4. Figure 2 This is a schematic diagram of the active heat dissipation system of the integrated solar-storage air conditioning equipment. An air valve 6 is added to the shell connecting the heat dissipation chamber 3 and the compression chamber 2. The air valve 6 can be opened to allow air to circulate between the heat dissipation chamber 3 and the compression chamber 2. The size of the air circulation channel can be controlled by adjusting the degree of opening of the valve leaf of the air valve 6; a ventilation channel is opened on the shell connecting the compression chamber 2 and the battery chamber 1; and a ventilation channel can also be opened on the outer shell of the battery chamber 1.

[0047] Embodiment 2: See also Figure 2 , is a schematic diagram of the heat dissipation structure of this embodiment. The difference of this embodiment is that a heat collecting plate is added to the shell connecting the compression chamber 2 and the battery chamber 1 to make the heat more concentrated.

[0048] The control method of this embodiment is specifically as follows.

[0049] Embodiment three: In the control method of this embodiment, when the air conditioner main control recognizes that the air conditioner is in heating operation, the air conditioner main control controls the air valve 6 to close, so that the air in the heat dissipation chamber 3 and the compression chamber 2 do not circulate. The control method of this embodiment uses the residual heat of the compressor in the compression chamber 2 to heat the energy storage battery 11 through the ventilation channel.

[0050] Embodiment 4: In the control method of this embodiment, the heat is concentrated by the heat collecting component 7 and then heated to the energy storage battery through the ventilation channel, so as to maintain the temperature at which the energy storage battery can work normally.

[0051] When the air conditioner main control recognizes that the air conditioner is in cooling operation: the air conditioner main control controls the air valve 6 to open, so that the air in the heat dissipation compartment 3 and the compression compartment 2 can circulate, and then an air circulation channel can be formed among the heat dissipation compartment 3, the compression compartment 2, and the battery compartment 1, and finally the heat is dissipated through the fan.

[0052] In the control method of this embodiment, the heat dissipation compartment 3, the compression compartment 2, and the battery compartment 1 are jointly controlled to form an active heat dissipation system. Different heat dissipation methods and air ducts are switched according to the cooling and heating modes of the photovoltaic air conditioner. The active heat dissipation system of the integrated household photovoltaic air conditioner equipment proposed in this proposal gives full play to the role of each component compartment and coordinates the control, which can not only solve the operation and startup problems of the energy storage battery inside the equipment, but also make the heat distribution inside the entire equipment uniform, improve the reliability of the product, and extend the service life.
