DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] According to an embodiment of the utility model, a photovoltaic air conditioning system is provided, such as Figure 1The system structure diagram of an embodiment of the photovoltaic air conditioning system of the utility model is shown. The photovoltaic air conditioning system may include: a water storage tank 7, a photovoltaic module, an air source heat pump unit and a thermoacoustic heat pump unit; the water storage tank 7 is used to provide domestic hot water for users. The photovoltaic modules are respectively connected to the air source heat pump unit and the thermoacoustic heat pump unit; specifically, the photovoltaic modules are respectively connected to the compressor 5 in the air source heat pump unit and the thermoacoustic engine 24 in the thermoacoustic heat pump unit. The photovoltaic module is used to convert light energy into electrical energy and then supply power to the compressor 5, and provide the heat energy converted from the light energy that has not been successfully converted in the process of converting light energy into electrical energy to the thermoacoustic engine 24 for the thermoacoustic heat pump unit to exchange heat with the water storage tank 7 to produce hot water.

[0022] The refrigerant circuit of the air source heat pump unit is provided with a compressor 5, a first heat exchanger 8, a first throttle valve 13, and a second heat exchanger 12. The first heat exchanger 8 has a first heat exchange pipeline; the first heat exchange pipeline of the first heat exchanger 8 is connected to the water storage tank 7 for heat exchange; the first heat exchanger 8 can exchange heat with the water in the water storage tank 7, and the second heat exchanger 12 is an outdoor heat exchanger. The pipeline on the exhaust port side of the compressor 5 passes through the second heat exchange pipeline of the first heat exchanger 8, the first throttle valve 13, and the second heat exchanger 12 in sequence, and is connected to the air intake port of the compressor 5.

[0023] When the first stop valve 9 is opened, the high-temperature and high-pressure refrigerant discharged from the compressor 5 passes through the first stop valve 9 and condenses in the first heat exchanger 8 to release heat. The heat released by the condensation can heat the water in the water storage tank 7 to produce hot water. After that, the refrigerant passes through the first throttle valve 13 and evaporates in the second heat exchanger 12 to absorb heat and flow back to the compressor 5. By using the first heat exchanger 8 to exchange heat and cool down the high-temperature and high-pressure refrigerant, the generated heat can be supplied to the water storage tank 7, so that the water in the water storage tank 7 begins to heat up.

[0024] The thermoacoustic heat pump unit has a thermoacoustic refrigerator 25, and the thermoacoustic refrigerator 25 has a refrigerator thermoacoustic radiator 19; the water storage tank 7 is also connected to the refrigerator thermoacoustic radiator 19 in the thermoacoustic refrigerator 25 for heat exchange through a heat exchange circuit, so that the refrigerator thermoacoustic radiator 19 can transfer the generated heat to the water storage tank 7 through the heat exchange circuit.

[0025] The thermoacoustic heat pump unit also has a thermoacoustic engine 24, which can provide acoustic energy to the thermoacoustic refrigerator 25, so that the heat generated by the thermoacoustic refrigerator 25 heats the water in the water storage tank 7. The thermoacoustic engine 24 includes: an engine thermoacoustic regenerator 22 and an engine high-temperature thermoacoustic absorber 23. The engine high-temperature thermoacoustic absorber 23 is used to absorb the thermal energy provided by the photovoltaic power generation module; the engine thermoacoustic regenerator 22 is used to convert the thermal energy absorbed by the engine high-temperature thermoacoustic absorber 23 into acoustic energy. Figure 1In the embodiment, after the switch 27 is closed, the heat energy generated by the photovoltaic power generation module can be transferred to the engine high temperature thermoacoustic heat absorber 23. The engine thermoacoustic engine 21 can release the heat generated when the thermoacoustic engine 24 is running.

[0026] The thermoacoustic refrigerator 25 further includes: a refrigerator low-temperature thermoacoustic heat absorber 17 and a refrigerator thermoacoustic heat regenerator 18 .

[0027] The refrigerator thermoacoustic regenerator 18 can receive and consume the acoustic energy generated by the engine thermoacoustic regenerator 22, so that the refrigerator low-temperature thermoacoustic heat absorber 17 absorbs heat to cool the room, and at the same time, the refrigerator thermoacoustic heat emitter 19 releases heat to heat the water in the water tank. The thermoacoustic refrigerator can be set indoors. That is, the thermoacoustic engine 24 can drive the thermoacoustic refrigerator 25 to operate, and the thermoacoustic refrigerator 25 can generate cold and heat during operation. The cold can be used for indoor cooling, and the heat can be used to make hot water. Figure 2 As shown, in cooling mode alone, hot water production mode alone, cooling + hot water production mode, heating + hot water production mode, the thermoacoustic heat pump unit can operate to achieve the corresponding mode, thereby improving the efficiency of hot water production and indoor cooling efficiency and improving user experience.

[0028] The photovoltaic module is used to convert solar energy into electrical energy and supply power to the air source heat pump unit; the photovoltaic module is also used to convert solar energy into thermal energy and provide thermal energy to the thermoacoustic engine 24 of the thermoacoustic heat pump unit. In the process of photovoltaic power generation, not all solar energy can be converted into electrical energy. Therefore, in order to efficiently utilize energy, this part of solar energy that cannot be converted into electrical energy is converted into thermal energy and provided to the thermoacoustic heat pump unit, which drives the thermoacoustic heat pump unit to produce hot water for users, which not only improves the efficiency of energy utilization, but also shortens the time used to produce hot water, improving the user experience.

[0029] The air source heat pump unit and the thermoacoustic heat pump unit can heat the water in the water tank to produce hot water. Among them, the hot water can be produced by the air source heat pump unit alone, the thermoacoustic heat pump unit alone, or the air source heat pump unit and the thermoacoustic heat pump unit together.

[0030] Figure 1 This is the system structure diagram of the photovoltaic air conditioning system. Figure 2 The photovoltaic air conditioning system can realize the operation modes of indoor cooling, indoor heating, indoor heating and water extraction, indoor cooling and hot water production, and indoor heating and hot water production.

[0031] In some embodiments, the first heat exchanger 8 also has a second heat exchange pipeline; a first stop valve 9, a third heat exchanger 14, a four-way valve 11, a second throttle valve 15, and a second stop valve 10 are also provided in the refrigerant circuit of the air source heat pump unit; wherein the third heat exchanger 14 is an indoor heat exchanger. The first stop valve 9 is arranged on the pipeline on the inlet side of the second heat exchange pipeline of the first heat exchanger 8; wherein, for the second heat exchange pipeline of the first heat exchanger 8, the side located at the compressor 5 is the inlet side, and the side located at the first throttle valve 13 is the outlet side; the pipeline on the exhaust port side of the compressor 5 is connected to the first valve port of the four-way valve 11 after passing through the second stop valve 10; the pipeline on the outlet side of the second heat exchange pipeline of the first heat exchanger 8 is connected to the second valve port of the four-way valve 11 after passing through the first throttle valve 13 and the second heat exchanger 12 in sequence; the air intake of the compressor 5 is connected to the third valve port of the four-way valve 11; the pipeline on the outlet side of the second heat exchange pipeline of the first heat exchanger 8 is also connected to the fourth valve port of the four-way valve 11 after passing through the second throttle valve 15 and the third heat exchanger 14 in sequence. Figure 1 As shown, in the first heat exchanger 8, the side close to the first stop valve 9 is the refrigerant inlet side, and the side close to the one-way valve 16 is the refrigerant outlet side.

[0032] When the first valve port a of the four-way valve 11 is connected to the second valve port b, the third valve port c is connected to the fourth valve port d, the first stop valve 9 is opened, and the second stop valve 10 is closed, the high-temperature and high-pressure refrigerant discharged from the compressor 5 passes through the first stop valve 9 and condenses and releases heat in the first heat exchanger 8. The released heat can heat the water in the water storage tank 7 to produce hot water. After that, the refrigerant passes through the second throttle valve 15 and evaporates and absorbs heat in the third heat exchanger 14. The cold released by evaporation can be used for indoor cooling, and then the refrigerant flows back to the compressor 5. In this process, the first throttle valve 13 is in a closed state, and the second throttle valve 15 is used for throttling. At this time, the system realizes the cooling + hot water production mode, and the air source heat pump unit can not only cool the room, but also produce hot water.

[0033] When the system is in cooling mode, Figure 1 and Figure 2 As shown, the first valve port a of the four-way valve 11 is connected to the second valve port b, the third valve port c is connected to the fourth valve port d, the stop valve 10 is opened, the throttle valve 13 is opened, the throttle valve 15 is opened, the switch 2 is closed, and the stop valve 9 is closed. The high-temperature and high-pressure refrigerant discharged from the compressor passes through the second heat exchanger 12 to condense and release heat, and then passes through the throttle valve 13 and the throttle valve 15 to enter the third heat exchanger 14 to evaporate and absorb heat, providing cooling for the room, and then the refrigerant flows back to the compressor 5.

[0034] When the first valve port a of the four-way valve 11 is connected to the fourth valve port d, the second valve port b is connected to the third valve port c, the first stop valve 9 is opened, and the second stop valve 10 is opened, a part of the high-temperature and high-pressure refrigerant discharged from the compressor 5 passes through the first stop valve 9 and condenses and releases heat in the first heat exchanger 8. The heat released by condensation can heat the water in the water storage tank 7 to produce hot water. Then, the refrigerant passes through the first throttle valve 13 and evaporates and absorbs heat in the second heat exchanger 12, and flows back to the compressor 5; another part of the high-temperature and high-pressure refrigerant discharged from the compressor 5 passes through the stop valve 10 and condenses and releases heat in the third heat exchanger 14. The released heat can heat the room. Then, the refrigerant passes through the second throttle valve 15 and the first throttle valve 13 and evaporates and absorbs heat in the second heat exchanger 12, and flows back to the compressor 5. In this process, the system realizes the heating + hot water production mode. The air source heat pump unit can not only heat the room, but also produce hot water.

[0035] When the system is in heating mode, Figure 1 and Figure 2 As shown, the first valve port a of the four-way valve 11 is connected to the fourth valve port d, the second valve port b is connected to the third valve port c, the stop valve 10 is opened, the throttle valve 13 is opened, the throttle valve 15 is opened, the switch 2 is closed, and the stop valve 9 is closed. The high-temperature and high-pressure refrigerant discharged from the compressor passes through the third heat exchanger 14 to condense and release heat to provide heat for the room. After that, the refrigerant passes through the throttle valve 13 and the throttle valve 15 and enters the second heat exchanger 12 to evaporate, absorb heat and flow back to the compressor 5.

[0036] This solution realizes multiple functional modes by producing hot water while cooling or heating, expanding the use scenarios of air conditioners and improving the user experience. At the same time, photovoltaic power generation is used to power the air source heat pump unit, further reducing the energy consumption of the air conditioner and improving energy utilization efficiency.

[0037] In some embodiments, a one-way valve 16 is provided at the outlet of the second heat exchange pipeline of the first heat exchanger 8, the inlet of the one-way valve 16 is connected to the second heat exchange pipeline of the first heat exchanger 8, and the outlet of the one-way valve 16 is connected to the first throttle valve 13 and the second throttle valve 15 respectively. The one-way valve 16 is used to prevent the refrigerant from flowing into the first heat exchanger 8 from the outlet of the first heat exchanger 8. In this system, the flow direction of the refrigerant in the first heat exchanger 8 is as follows: Figure 1 As shown, the refrigerant always flows from one side of the first stop valve 9 to one side of the one-way valve 16. The refrigerant flowing out of the second heat exchanger 12 or the third heat exchanger 14 may be at a lower temperature, so the one-way valve 16 can be added to prevent the low-temperature refrigerant from flowing into the first heat exchanger 8 and affecting the water temperature in the water storage tank.

[0038] In some embodiments, the heat exchange circuit includes: a first heat exchange component, a second heat exchange component, a third stop valve 26 and a pump body 6; the first heat exchange component is connected to the second heat exchange component to form a circuit; the third stop valve 26 and the pump body 6 are also provided on the circuit. The circuit contains refrigerant; the third stop valve 26 is used to control the on and off of the circuit; the pump body 6 is used to provide power for the flow of the refrigerant when the circuit is connected. The first heat exchange component can exchange heat with the thermoacoustic radiator 19 of the refrigerator, and the second heat exchange component can exchange heat with the water storage tank 7. When the third stop valve 26 is turned on and the pump body 6 is turned on, the first heat exchange component absorbs the heat released by the thermoacoustic radiator 19 of the refrigerator to form a high-temperature refrigerant, and then the high-temperature refrigerant releases heat in the second heat exchange component to heat the water in the water storage tank 7. By using the refrigerant to transfer the heat generated by the thermoacoustic heat pump unit to the water storage tank, the efficiency of heat use can be improved and energy waste can be avoided. At the same time, there is no need to set the thermoacoustic refrigerator near the water storage tank, which improves the flexibility of system implementation.

[0039] In some embodiments, the thermoacoustic heat pump unit further includes: a phase adjustment mechanism 20, a conversion component 28, and a battery 3; the phase adjustment mechanism 20 is arranged between the thermoacoustic engine 24 and the thermoacoustic refrigerator 25; the phase adjustment mechanism 20 is used to adjust the acoustic impedance between the thermoacoustic engine 24 and the thermoacoustic refrigerator 25, so that the thermoacoustic engine 24 and the thermoacoustic refrigerator 25 operate under a preset sound field. Since the thermoacoustic engine transmits acoustic energy to the thermoacoustic refrigerator, and the acoustic energy generated by the thermoacoustic engine may not match the acoustic energy required by the thermoacoustic refrigerator, energy transfer is lost and the operating efficiency is reduced. Therefore, by setting a phase adjustment mechanism to adjust the acoustic impedance, it is made to operate under a preset sound field, thereby improving the operating efficiency of the whole machine.

[0040] The conversion component 28 is connected to the battery 3. The conversion component 28 can convert the acoustic energy generated by the thermoacoustic engine 24 into electrical energy and store it in the battery 3. When the thermoacoustic heat pump unit is not needed to produce hot water or indoor cooling, the energy generated by the thermoacoustic engine can be converted into electrical energy and stored, and then supplied to the air source heat pump system, thereby further improving energy utilization efficiency.

[0041] In some embodiments, a baffle is provided in the phase adjustment mechanism 20. The baffle is used to control the propagation path of the acoustic energy generated by the thermoacoustic engine 24. When the water temperature in the water storage tank 7 is lower than the preset temperature, the baffle is in an open state, so that the acoustic energy generated by the thermoacoustic engine 24 is transmitted to the thermoacoustic refrigerator 25, so that the thermoacoustic radiator 19 releases heat to heat the water in the water storage tank; when the water temperature in the water storage tank 7 is higher than the preset temperature, the baffle is in a closed state, so that the acoustic energy generated by the thermoacoustic engine 24 is transmitted to the conversion component 28, so that the storage battery 3 starts to charge.

[0042] The transfer path of the sound energy generated by the thermoacoustic engine is controlled by setting a baffle, and it is controlled according to the water temperature of the water tank, thereby avoiding energy waste. When the thermoacoustic heat pump unit is not needed to produce hot water or indoor cooling, the energy generated by it is stored, thereby improving energy utilization efficiency.

[0043] In some embodiments, the photovoltaic module includes a photovoltaic panel 1 and a controller 4; the controller 4 is connected to the photovoltaic panel 1 and the battery 3 respectively. The photovoltaic panel 1 is used to absorb solar energy and convert it into electrical energy; the controller 4 is used to convert the electrical energy generated by the photovoltaic panel 1 or the electrical energy in the battery 3 into AC power that can be used by the air source heat pump unit and supply power to the air source heat pump unit. Figure 1 As shown, when the switch 2 is closed, the battery 3 can transfer electric energy to the controller 4. By setting the controller to convert the electric energy, the electric energy generated by photovoltaic power and the electric energy stored in the battery can be used by the air source heat pump unit.

[0044] By adopting the technical solution of this embodiment, the photovoltaic power generation module is used to supply energy to the air source heat pump unit and the thermoacoustic heat pump unit, so that the air source heat pump unit and the thermoacoustic heat pump unit heat the water in the water storage tank to produce hot water. This not only reduces the energy consumption of the air conditioning system and improves the efficiency of producing hot water, but also makes fuller use of the energy generated by the photovoltaic power generation module, thereby improving energy utilization efficiency.

[0045] According to an embodiment of the utility model, an air conditioner corresponding to the photovoltaic air conditioning system is also provided. The air conditioner may include: the photovoltaic air conditioning system described above.
