Due to their numerous advantages, including safety and energy efficiency, air source heat pump heaters have been widely accepted and have become an essential basic facility in northern China.
[0003] However, current air source heat pump heating systems suffer from low air energy utilization and poor energy-saving performance. Summary of the Invention

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0035] Please see Figure 1 This application provides an air source heating system 10, which is used to heat a place that needs to be heated by using air energy.
[0036] In some embodiments, the air heating system 10 includes an air source heat pump 11, a terminal device 12, a main heat storage device 13, and a standby heat storage device 14. The main heat storage device 13 and the standby heat storage device 14 are connected in parallel between the air source heat pump 11 and the terminal device 12. A heat exchange medium flows through the air source heating system 10. The heat exchange medium absorbs air energy at the air source heat pump 11. After absorbing air energy, the heat exchange medium can be selectively introduced into the main heat storage device 13 or the standby heat storage device 14. The main heat storage device 13 and the standby heat storage device 14 achieve heat storage by storing the heat exchange medium that has absorbed air energy. When heating is required in the area to be heated, the heat exchange medium in the main heat storage device 13 and the standby heat storage device 14 can be introduced into the terminal device 12 to release heat and heat the area to be heated. The heat exchange medium that has released heat in the terminal device 12 can flow back to the air source heat pump 11 to absorb air energy again. Thus, the heat exchange medium circulates within the air source heating system 10 from the air source heat pump 11 to the main heat storage device 13 or the standby heat storage device 14, then to the terminal device 12, and finally back to the air source heat pump 11. During this circulation, heat is absorbed at the air source heat pump 11, stored at the main heat storage device 13 and the standby heat storage device 14, and released at the terminal device 12, thereby achieving heating using air energy.
[0037] In some embodiments, the heat exchange medium may be water, but it may also be other heat exchange media in the related art, and this application is not limited thereto.
[0038] The air source heat pump 11 is used to store air energy in the heat exchange medium. The specific structure and configuration of the air source heat pump 11 can be found in related technologies, and will not be described in detail here.
[0039] Terminal device 12 is used to install in the area to be heated to provide heating. Terminal device 12 can be underfloor heating, air conditioning, radiators, water heaters, etc. It is understood that terminal device 12 can automatically turn on when the indoor temperature of the area to be heated is lower than a threshold, or can be turned on by the user as needed.
[0040] The main heat storage device 13 is used to connect the air source heat pump 11 and the terminal device 12, and to disconnect from the air source heat pump 11 and the terminal device 12 after the terminal device 12 reaches the temperature and stops.
[0041] It is understandable that when the main heat storage device 13 is connected to the air source heat pump 11 and the terminal device 12, the heat exchange medium can circulate among the three, thereby realizing heating using air energy.
[0042] For example, the main heat storage device 13 is used to connect the air source heat pump 11 and the terminal device 12 during the high-temperature period of the day.
[0043] For example, the main thermal storage device 13 can be a hot water storage tank. It is understood that the main thermal storage device 13 can also adopt other structures in the related technology, as long as thermal storage can be achieved, and this application is not limited thereto.
[0044] The standby thermal storage device 14 is connected in parallel with the main thermal storage device 13 between the air source heat pump 11 and the terminal device 12. The standby thermal storage device 14 is used to connect with the air source heat pump 11 for thermal storage after the terminal device 12 reaches the temperature and stops, and to connect the air source heat pump 11 and the terminal device 12 after the thermal storage is completed.
[0045] It is understood that when the standby heat storage device 14 is connected to the air source heat pump 11, the heat exchange medium can flow between the air source heat pump 11 and the standby heat storage device 14, so that the heat exchange medium after absorbing heat at the air source heat pump 11 can flow to the standby heat storage device 14 to achieve heat storage; when the standby heat storage device 14 is full of heat exchange medium, the heat exchange medium can circulate between the air source heat pump 11 and the standby heat storage device 14, thereby ensuring that the heat exchange medium in the standby heat storage device always stores a high amount of heat, which helps to ensure the heating effect of using the standby heat storage device 14 during low temperature periods.
[0046] It is understandable that the specific details of the shutdown process at Dawen can be found in relevant technologies, and this application will not elaborate on them.
[0047] For example, the standby heat storage device 14 is used to connect with the air source heat pump 11 for heat storage after the terminal device 12 reaches its temperature and shuts down during the high-temperature period of the day, and to connect the air source heat pump 11 with the terminal device 12 during the low-temperature period of the day. The ambient temperature during the low-temperature period is lower than the ambient temperature during the high-temperature period.
[0048] The air source heating system provided in this application sets up a backup heat storage device 14 connected in parallel with the main heat storage device 13. The backup heat storage device 14 starts storing heat after the terminal device 12 reaches the temperature and stops. After the heat storage is completed, the air source heat pump 11 and the terminal device 12 are connected to provide heating. In this way, the utilization rate of air energy can be improved and energy saving can be achieved without affecting the normal heating.
[0049] In some embodiments, the heat storage capacity of the backup heat storage device 14 is greater than that of the main heat storage device 13. By setting the heat output capacity of the backup heat storage device 14 to be greater than that of the main heat storage device 13, it helps to store as much air energy as possible during high-temperature periods, thereby ensuring the heating effect during low-temperature periods.
[0050] For example, the capacity of the standby heat storage device 14 is greater than that of the main heat storage device 13. Thus, compared with the main heat storage device 13, the standby heat storage device 14 can store more heat exchange medium that has absorbed heat at the air source heat pump 11 and then flows to the air source heat pump 11.
[0051] In some embodiments, during the operation of the air source heating system, the main heat storage device 13 is also used to connect the air source heat pump 11 and the terminal device 12 during the normal temperature period of the day. The ambient temperature during the normal temperature period is higher than the ambient temperature during the low temperature period, but lower than the ambient temperature during the high temperature period.
[0052] In one embodiment, the sum of the high-temperature period, the normal-temperature period, and the low-temperature period constitutes a complete day. By making the sum of the high-temperature period, the normal-temperature period, and the low-temperature period constitute a complete day, the control logic of the air source heating system can be simplified, which helps to avoid the problem of system malfunction due to the inability to determine the current time period. At the same time, it also helps to improve the utilization rate of air energy.
[0053] It should be noted that the high-temperature period, normal-temperature period, and low-temperature period can be set according to actual needs.
[0054] In some embodiments, for different dates within the same season, periods of day when the outdoor temperature is higher than a first preset temperature can be classified as high-temperature periods, periods of day when the outdoor temperature is lower than a second preset temperature can be classified as low-temperature periods, and periods when the outdoor temperature is between the second preset temperature and the first preset temperature can be classified as normal-temperature periods. For the same season, the first preset temperature and the second preset temperature are constant values.
[0055] In some embodiments, for different dates within the same season, the high-temperature period, normal-temperature period, and low-temperature period can be divided according to the temperature range of the region where the system is located on that specific date. For example, the temperature value at one-third of the temperature range can be used as the boundary between the normal-temperature period and the low-temperature period, and the temperature value at two-thirds of the temperature range can be used as the boundary between the normal-temperature period and the high-temperature period. For instance, on December 17, 2022, the temperature range of the location of the air source heating system 10 is 5℃ to 20℃. Therefore, the temperature value of 10℃ at one-third of the temperature range can be used as the boundary between the normal-temperature period and the low-temperature period; that is, the period with a temperature value greater than 5℃ and less than or equal to 10℃ is classified as the low-temperature period. Similarly, the temperature value of 15℃ at two-thirds of the temperature range can be used as the boundary between the normal-temperature period and the high-temperature period; that is, the period with a temperature value greater than 10℃ and less than or equal to 15℃ is classified as the normal-temperature period, and the period with a temperature value greater than 15℃ and less than or equal to 20℃ is classified as the high-temperature period. This is merely an example and is not intended to limit the scope of this application.
[0056] In some embodiments, the air source heating system 10 may further include a pump body 15. The pump body 15 is connected between the main heat storage device 13 and the terminal device 12, and between the standby heat storage device 14 and the terminal device 12. The pump body is used to pump the heat exchange medium from the main heat storage device 13 or the standby heat storage device 14 to the terminal device 12. By connecting the pump body 15 between the main heat storage device 13 and the terminal device 12, and between the standby heat storage device 14 and the terminal device 12, it helps to ensure smoother flow of the heat exchange medium within the system.
[0057] In some embodiments, the air source heating system 10 may also include a controller (not shown). The controller is used to control the on / off connection between the air source heat pump 11, the main heat storage device 13, the standby heat storage device 14, and the terminal device 12. By including a controller in the air source heating system 10, it helps to ensure the automated operation of the system.
[0058] In some embodiments, the air source heating system 10 also includes a piping structure. The piping structure connects the air source heat pump 11, the main heat storage device 13, the standby heat storage device 14, and the terminal device 12, and is used to selectively connect / disconnect the heat exchange pathways between the air source heat pump 11 and the main heat storage device 13, between the air source heat pump 11 and the standby heat storage device 14, between the main heat storage device 13 and the terminal device 12, between the standby heat storage device 14 and the terminal device 12, and / or between the terminal device 12 and the air source heat pump 11 at different operating stages of the air source heating system 10.
[0059] Specifically, the piping structure includes a first pipe 1011, a second pipe 1012, a third pipe 1013, a fourth pipe 1014, a fifth pipe 1015, and a sixth pipe 1016. The first pipe 1011 connects the terminal device 12 to the air source heat pump 11. The second pipe 1012 connects the air source heat pump 11 to the main heat storage device 13. The third pipe 1013 connects the main heat storage device 13 to the terminal device 12. The fourth pipe 1014 connects the air source heat pump 11 to the standby heat storage device 14. The fifth pipe 1015 connects the standby heat storage device 14 to the terminal device 12. The sixth pipe 1016 connects the standby heat storage device 14 to the first pipe 1011.
[0060] For example, during the high-temperature period of the day, after the terminal device 12 is turned on, the first pipeline 1011 connects the air source heat pump 11 and the terminal device 12, the second pipeline 1012 connects the main heat storage device 13 and the air source heat pump 11, and the third pipeline 1013 connects the main heat storage device 14 and the terminal device 12. Thus, a loop is formed between the air source heat pump 11, the main heat storage device 13 and the terminal device 12. After the heat exchange medium absorbs heat at the air source heat pump 11, it is introduced into the main heat storage device 13 for heat storage, and then flows through the main heat storage device 13 to the terminal device 12 for heating. After releasing heat in the terminal device 12, it flows back to the air source heat pump 11.
[0061] When the terminal device 12 reaches its temperature and shuts down, the first pipe 1011 disconnects the passage between the air source heat pump 11 and the terminal device 12, the second pipe 1012 disconnects the passage between the air source heat pump 11 and the main heat storage device 13, the third pipe 1013 disconnects the passage between the main heat storage device 13 and the terminal device 12, then the fourth pipe 1014 connects the air source heat pump 11 and the standby heat storage device 14, the fifth pipe 1015 disconnects the passage between the standby heat storage device 14 and the terminal device 12, and the sixth pipe 1016 connects the standby heat storage device 14 and the first pipe 1011, thereby connecting the standby heat storage device 14 and the air source heat pump 11. Thus, a loop is formed between the air source heat pump 11 and the standby heat storage device 14. After the heat exchange medium absorbs heat at the air source heat pump 11, it is introduced into the standby heat storage device 14, thereby realizing the heat storage using the standby heat storage device 14.
[0062] During the normal temperature period of the day, after the terminal device 12 is turned on, the first pipeline 1011 connects the air source heat pump 11 and the terminal device 12, the second pipeline 1012 connects the main heat storage device 13 and the air source heat pump 11, and the third pipeline 1013 connects the main heat storage device 14 and the terminal device 12. Thus, a loop is formed between the air source heat pump 11, the main heat storage device 13 and the terminal device 12. After the heat exchange medium absorbs heat at the air source heat pump 11, it is introduced into the main heat storage device 13 for heat storage, and then flows through the main heat storage device 13 to the terminal device 12 for heating. After releasing heat in the terminal device 12, it flows back to the air source heat pump 11.
[0063] During the low-temperature period of the day, the first pipe 1011 connects the air source heat pump 11 to the terminal device 12, the second pipe 1012 disconnects the passage between the air source heat pump 11 and the main heat storage device 13, the third pipe 1013 disconnects the passage between the main heat storage device 13 and the terminal device 12, the fourth pipe 1014 connects the air source heat pump 11 to the standby heat storage device 14, the fifth pipe 1015 connects the standby heat storage device 14 to the terminal device 12, and the sixth pipe 1016 disconnects the standby heat storage device 14 from the first pipe 1011. Thus, a loop is formed between the air source heat pump 11, the standby heat storage device 14, and the terminal device 12. By introducing the heat exchange medium that stores heat in the standby heat storage device 14 during the high-temperature period into the terminal device 12 for heating, the utilization rate of air energy can be improved, which helps to achieve energy saving.
[0064] Furthermore, the piping structure may also include a first valve 1021, a second valve 1022, a third valve 1023, a fourth valve 1024, a fifth valve 1025, a sixth valve 1026, a seventh valve 1027, an eighth valve 1028, and a ninth valve 1029. The first valve 1021 is located on the first pipe 1011 and is positioned close to the air source heat pump 11. The first valve 1021 can be understood as the inlet valve of the air source heat pump 11. The second valve 1022 and the third valve 1023 are located on the second pipe 1012. The second valve 1022 is positioned close to the air source heat pump 11. The second valve 1022 can be understood as the outlet valve of the air source heat pump 11. The third valve 1023 is positioned close to the main heat storage device 13. The third valve 1023 can be understood as the inlet valve of the main heat storage device 13. The fourth valve 1024 and the fifth valve 1025 are located on the third pipe 1013. The fourth valve 1024 is positioned close to the main heat storage device 13. The fourth valve 1024 can be understood as the outlet valve of the main thermal storage device 13. The fifth valve 1025 is located near the terminal device 12. The fifth valve 1025 can be understood as the inlet valve of the terminal device 12. The sixth valve 1026 is located on the fourth pipeline 1014. The sixth valve 1026 can be understood as the inlet valve of the standby thermal storage device. The fourth pipeline 1014 is connected to the second pipeline 1012, and the connection point is located between the second valve 1022 and the third valve 1023. The seventh valve 1027 is located on the fifth pipeline 1015. The seventh valve 1027 can be understood as the outlet valve of the standby thermal storage device 14. The fifth pipeline 1015 is connected to the third pipeline 1013, and the connection point is located between the fourth valve 1024 and the fifth valve 1025. The eighth valve 1028 is located on the sixth pipeline 1016. The eighth valve 1028 can be understood as another outlet valve of the standby thermal storage device 14. The ninth valve 1029 is located on the first pipeline 1011 and close to the terminal device 12. The ninth valve 1029 can be understood as the outlet valve of the terminal device 12. The sixth pipeline 1016 is connected to the first pipeline 1011, and the connection point is located between the first valve 1021 and the ninth valve 1029.
[0065] For example, during the hottest part of the day, after the terminal device 12 is turned on, both the first valve 1021 and the ninth valve 1029 are opened, connecting the first pipeline 1011 to the air source heat pump 11 and the terminal device 12; both the second valve 1022 and the third valve 1023 are opened, connecting the second pipeline 1012 to the main heat storage device 13 and the air source heat pump 11; and both the fourth valve 1024 and the fifth valve 1025 are opened, connecting the third pipeline 1013 to the main heat storage device 14 and the terminal device 12. Thus, a loop is formed between the air source heat pump 11, the main heat storage device 13, and the terminal device 12. The heat exchange medium absorbs heat at the air source heat pump 11, then enters the main heat storage device 13 for heat storage, and then flows through the main heat storage device 13 to the terminal device 12 for heating. After releasing heat in the terminal device 12, it flows back to the air source heat pump 11.
[0066] When the terminal device 12 reaches its operating temperature and shuts down, the ninth valve 1029 closes, disconnecting the passage between the air source heat pump 11 and the terminal device 12 via the first pipeline 1011; the third valve 1023 closes, disconnecting the passage between the air source heat pump 11 and the main heat storage device 13 via the second pipeline 1012; the fourth valve 1024 closes, disconnecting the passage between the main heat storage device 13 and the terminal device 12 via the third pipeline 1013; the second valve 1022 and the sixth valve 1026 open, connecting the air source heat pump 11 and the standby heat storage device 14 via the fourth pipeline 1014; the seventh valve 1027 closes, disconnecting the passage between the standby heat storage device 14 and the terminal device 12 via the fifth pipeline 1015; the eighth valve 1028 opens, connecting the standby heat storage device 14 and the first pipeline 1011 via the sixth pipeline 1016; the first valve 1021 opens, connecting the first pipeline 1011 and the air source heat pump 11, and further connecting the standby heat storage device 14 and the air source heat pump 11. Thus, a circuit is formed between the air source heat pump 11 and the standby heat storage device 14. After the heat exchange medium absorbs heat at the air source heat pump 11, it is introduced into the standby heat storage device 14, thereby realizing the use of the standby heat storage device 14 for heat storage.
[0067] During the normal temperature period of day, after the terminal device 12 is turned on, the first valve 1021 and the ninth valve 1029 open, connecting the first pipeline 1011 to the air source heat pump 11 and the terminal device 12; the second valve 1022 and the third valve 1023 open, connecting the second pipeline 1012 to the main heat storage device 13 and the air source heat pump 11; the fourth valve 1024 and the fifth valve 1025 open, connecting the third pipeline 1013 to the main heat storage device 14 and the terminal device 12. Thus, a loop is formed between the air source heat pump 11, the main heat storage device 13, and the terminal device 12. The heat exchange medium absorbs heat at the air source heat pump 11, then enters the main heat storage device 13 for heat storage, and then flows through the main heat storage device 13 to the terminal device 12 for heating. After releasing heat in the terminal device 12, it flows back to the air source heat pump 11.
[0068] During the low-temperature period of the day, the first valve 1021 and the ninth valve 1029 are opened, connecting the first pipe 1011 to the air source heat pump 11 and the terminal device 12; the third valve 1023 is closed, disconnecting the second pipe 1012 from the air source heat pump 11 and the main heat storage device 13; the fourth valve 1024 is closed, disconnecting the third pipe 1013 from the main heat storage device 13 and the terminal device 12; the second valve 1022 and the sixth valve 1026 are opened, connecting the fourth pipe 1014 to the air source heat pump 11 and the standby heat storage device 14; the seventh valve 1027 and the fifth valve 1025 are opened, connecting the fifth pipe 1015 to the standby heat storage device 14 and the terminal device 12; and the eighth valve 1028 is closed, disconnecting the sixth pipe 1016 from the standby heat storage device 14 and the first pipe 1011. Thus, a loop is formed between the air source heat pump 11, the standby heat storage device 14, and the terminal device 12. By introducing the heat exchange medium that stores heat in the standby heat storage device 14 during high-temperature periods into the terminal device 12 for heating, the utilization rate of air energy can be improved, which helps to achieve energy saving.
[0069] Please see Figure 2 Based on the same inventive concept, this application also provides an air source heating method. This method can be applied to the aforementioned air source heating system 10, or to the control device of the aforementioned air source heating system 10, such as the controller of the aforementioned air source heating system 10, or a third-party electronic device connected to the aforementioned air source heating system 10 via a signal.
[0070] In some embodiments, the method may include the following steps.
[0071] Step S13: After determining that the terminal device has reached the temperature and stopped, disconnect the main heat storage device from the air source heat pump and the terminal device, disconnect the standby heat storage device from the terminal device, and connect the standby heat storage device to the air source heat pump to perform heat storage.
[0072] Step S15: After the heat storage is completed, connect the standby heat storage device, the air source heat pump and the terminal device to provide heating to the terminal device.
[0073] In one embodiment, please refer to Figure 3 Step S13 includes: after determining that the terminal device has reached the temperature and stopped during the high-temperature period of the day, disconnecting the main heat storage device from the air source heat pump and the terminal device, disconnecting the standby heat storage device from the terminal device, and connecting the standby heat storage device to the air source heat pump for heat storage.
[0074] Step S15 includes: during the low-temperature period of the day, connecting the standby thermal storage device, the air source heat pump, and the terminal device to provide heating to the terminal device.
[0075] The air source heating method also includes step S14: during normal temperature periods of the day, connecting the main heat storage device, the air source heat pump and the terminal device.
[0076] In one embodiment, please refer to Figure 4 The air source heating method, in addition to steps S13 to S15, also includes step S12: acquiring temperature data and dividing the day into high-temperature, normal-temperature, and low-temperature periods based on the temperature data. It can be understood that the time point for acquiring the temperature data can be a point in time from the previous day. This time point can correspond to the time when the air source heating system 10 first receives the user's control command to activate the energy-saving mode. For example, if the user first issues the control command to the air source heating system to activate the energy-saving mode at 18:00, then the temperature data for the next day can be acquired at 18:00 every day, and the high-temperature, normal-temperature, and low-temperature periods for the next day can be divided based on the temperature data. This time point can also correspond to the time when the air source heating system previously received the user's control command to activate the energy-saving mode. For example, if the user previously issued the control command to the air source heating system to activate the energy-saving mode at 15:00, then the temperature data for the next day can be acquired at 15:00 every day, and the high-temperature, normal-temperature, and low-temperature periods for the next day can be divided based on the temperature data. Of course, this time point can also be the time when the user sends the control command to the air source heating system to turn on the energy-saving mode. In other words, after receiving the control command to turn on the energy-saving mode from the user, the air source heating system immediately obtains the temperature data of the day, divides it according to the temperature data, and then operates according to the operating mode corresponding to each temperature period.
[0077] It is understandable that users can issue control commands to enter energy-saving mode through a third-party controller or mobile application of the air source heating system 10. The air source heating system 10 has network connectivity and obtains temperature data through the network.
[0078] In one embodiment, please refer to Figure 5 In addition to steps S12 to S15, the air source heating method may also include step S11 before acquiring temperature data: determining that the air source heating system is in energy-saving control mode.
[0079] In one embodiment, the air source heating method further includes: during the high-temperature period of the day, after determining that the terminal device meets the start-up conditions, connecting the main heat storage device, the air source heat pump and the terminal device to provide heating to the terminal device.
