[0029] The following combines Figures 1 - 3 to describe the heat pump unit and control method of the present invention.

[0030] An embodiment of the first aspect of the present invention provides a heat pump unit, such as Figure 1 shown, the heat pump unit includes a heating system 10, a hot water tank 20, and a heat pump system 30. The heat pump system 30 includes a plurality of heat pump hosts, and each heat pump host is respectively connected to the heating system 10 and the hot water tank 20 through a control valve.

[0031] The control valve has a first working position and a second working position. In the first working position, the heat pump host is connected to the heating system 10 through the control valve. In the second working position, the heat pump host is connected to the hot water tank 20 through the control valve.

[0032] It can be understood that the control valve has two working positions, namely the first working position and the second working position; when the control valve is in the first working position, the heat pump host is connected to the heating system 10 through the control valve, and the water of the heat pump host enters the heating system 10 through the control valve to realize the heating function. After the heating or cooling is realized in the heating system 10, it then flows back to the heat pump host; when the control valve is in the second working position, the heat pump host is connected to the hot water tank 20 through the control valve, the heat pump host turns on the heating mode, and the hot water of the heat pump host enters the hot water tank 20 through the control valve to realize the hot water heating function; thus, by switching the control valve between the first working position and the second working position, the switching between the heating function and the hot water heating function can be realized.

[0033] Specifically, the heat pump system 30 includes a plurality of heat pump hosts, each heat pump host is connected with a control valve, and each control valve is respectively connected to the heating system 10 and the hot water tank 20. Then, the plurality of heat pump hosts correspond to a plurality of control valves. Some control valves are in the first working position, and the rest of the control valves are in the second working position. Then, the heat pump hosts connected to the control valves in the first working position are connected to the heating system 10 to realize the heating function, and the heat pump hosts connected to the control valves in the second working position are connected to the hot water tank 20 to realize the hot water heating function. Thus, the heating function and the hot water heating function can be realized simultaneously through a plurality of heat pump hosts.

[0034] For the heat pump unit provided by the embodiment of the present invention, the heat pump host is respectively connected to the heating system 10 and the hot water tank 20 through the control valve. When the control valve is in the first working position, the heat pump host is connected to the heating system 10 through the control valve to realize the heating function; when the control valve is in the second working position, the heat pump host is connected to the hot water tank 20 through the control valve to realize the hot water heating function. Thus, by switching the control valve between the first working position and the second working position, the switching between the heating function and the hot water heating function can be realized; and the heating function and the hot water heating function can be realized simultaneously through a plurality of heat pump hosts, thereby meeting the requirements of multiple working modes, improving the energy utilization efficiency and the user experience.

[0035] In some embodiments, such as Figure 1As shown, the heating system 10 includes a buffer water tank 11, a heating pipeline 12 and a heat exchange component. The buffer water tank 11 is connected to a control valve; the inlet and outlet of the heating pipeline 12 are connected to the buffer water tank 11; the heat exchange component is arranged on the heating pipeline 12.

[0036] Specifically, the inlet of the heating pipeline 12 is connected to the upper part of the buffer water tank 11, a heating water pump 15 is arranged on the water inlet side of the heating pipeline 12, the outlet of the heating pipeline 12 is connected to the lower part of the buffer water tank 11, and the heat exchange component is arranged on the heating pipeline 12.

[0037] The heating function includes heating and cooling. When the heating function is realized, the control valve is in the first working position, the heat pump host connected to the control valve in the first working position starts the heating mode, the hot water of the heat pump host enters the buffer water tank 11 through the control valve. After the heating water pump 15 is started, the water enters the heat exchange component to meet the heating demand. After heat exchange through the heat exchange component, it then flows back to the buffer water tank 11 and then back to the heat pump host; when the cooling function is realized, the control valve is in the first working position, the heat pump host connected to the control valve in the first working position starts the cooling mode, the cold water of the heat pump host enters the buffer water tank 11 through the control valve. After the heating water pump 15 is started, the water enters the heat exchange component to meet the cooling demand. After heat exchange through the heat exchange component, it then flows back to the heat pump host.

[0038] Furthermore, the heating system 10 includes multiple heat exchange components, and the multiple heat exchange components can enable the system to more flexibly respond to different environmental conditions and user requirements. For example, at different outdoor temperatures, the working states of the respective heat exchange components can be adjusted to optimize energy utilization and maintain efficient heating performance; and the multiple heat exchange components can reasonably distribute the heat exchange load, reduce the burden on a single heat exchange component, and reduce wear caused by overuse, thereby extending the service life of the system.

[0039] Optionally, the heat exchange component includes a heat exchanger 13 and a control switch 14. The heat exchanger 13 can adopt a fan coil unit, and the control switch 14 can adopt an electromagnetic valve. Of course, in other embodiments, the heat exchanger 13 can also adopt other forms such as floor heating and radiators.

[0040] In some embodiments, a temperature measuring element is arranged on the hot water tank 20. When the control valve is in the second working position, the heat pump host is connected to the hot water tank 20 through the control valve to realize the function of making hot water. The current temperature of the water in the hot water tank 20 is monitored through the temperature measuring element, and when the current temperature is greater than or equal to the temperature threshold, it indicates that the function of making hot water is completed, and the control valve in the second working position is controlled to switch from the second working position to the first working position.

[0041] In some embodiments, the control valve includes a three-way valve, which includes a first port, a second port, and a third port. The first port is connected to the heat pump main unit, the second port is connected to the heating system 10, and the third port is connected to the hot water tank 20. When the control valve is in the first working position, the first port and the second port are in communication, and the third port and the first port are disconnected. When the control valve is in the second working position, the first port and the third port are in communication, and the first port and the second port are disconnected.

[0042] In an exemplary embodiment, the heat pump unit includes a heating system 10, a hot water tank 20, a heat pump system 30, and two control valves. The heating system 10 includes a buffer water tank 11, a heating pipeline 12, and a heat exchange component. The water inlet and the water outlet of the heating pipeline 12 are connected to the buffer water tank 11. The heat exchange component is arranged in the heating pipeline 12. The heat pump system 30 includes two heat pump main units, namely a first heat pump main unit 31 and a second heat pump main unit 33. The two control valves are a first three-way valve 41 and a second three-way valve 42 respectively. The outlet of the first heat pump main unit 31 is connected to the first port of the first three-way valve 41. A first main pump 32 is arranged at the outlet of the first heat pump main unit 31. The second port of the first three-way valve 41 is connected to the inlet of the buffer water tank 11. The outlet of the buffer water tank 11 is connected to the inlet of the first heat pump main unit 31. The third port of the first three-way valve 41 is connected to the inlet of the hot water tank 20. The outlet of the hot water tank 20 is connected to the inlet of the first heat pump main unit 31. The outlet of the second heat pump main unit 33 is connected to the first port of the second three-way valve 42. A second main pump 34 is arranged at the outlet of the second heat pump main unit 33. The second port of the second three-way valve 42 is connected to the inlet of the buffer water tank 11. The outlet of the buffer water tank 11 is connected to the inlet of the second heat pump main unit 33. The third port of the second three-way valve 42 is connected to the inlet of the hot water tank 20. The outlet of the hot water tank 20 is connected to the inlet of the second heat pump main unit 33.

[0043] The heat pump unit in this embodiment can achieve the following four functions: First, it can achieve the functions of refrigeration and hot water production.

[0044] When the unit receives the instructions for refrigeration and hot water production, the first heat pump main unit 31 starts the refrigeration mode. The first three-way valve 41 is in the first working position. Then, the cold water from the first heat pump main unit 31 directly enters the buffer water tank 11 through the first three-way valve 41. After the heating water pump 15 is started, the water enters the heat exchange component 13, and the refrigeration requirement can be achieved.

[0045] At the same time, the second heat pump main unit 33 starts the heating mode. The second three-way valve 42 is in the second working position. Then, the hot water from the second heat pump main unit 33 directly enters the hot water tank 20 through the second three-way valve 42, and the hot water production requirement can be achieved. Thus, the functions of refrigeration and hot water production can be achieved simultaneously.

[0046] Further, by obtaining the current temperature of the hot water tank 20, where the current temperature represents the water temperature in the hot water tank 20, when the current temperature is greater than or equal to the temperature threshold, the second three-way valve 42 is switched from the second working position to the first working position, and the second heat pump main unit 33 switches to the cooling mode to continue to meet the user's cooling demand.

[0047] Second, to achieve the heating and hot water supply functions.

[0048] When the unit receives the heating and hot water supply instructions, the first heat pump main unit 31 turns on the heating mode. If the first three-way valve 41 is in the first working position, the hot water from the first heat pump main unit 31 directly enters the buffer water tank 11 through the first three-way valve 41. After the heating water pump 15 is turned on, the water enters the heat exchange component 13, and the heating demand can be met.

[0049] Meanwhile, the second heat pump main unit 33 turns on the heating mode. If the second three-way valve 42 is in the second working position, the hot water from the second heat pump main unit 33 directly enters the hot water tank 20 through the second three-way valve 42, and the hot water supply demand can be met, thus achieving the heating and hot water supply functions.

[0050] It should be noted that when the current temperature of the hot water tank 20 is greater than or equal to the temperature threshold, the second three-way valve 42 is switched from the second working position to the first working position, and the hot water from the second heat pump main unit 33 enters the buffer water tank 11 to continue to meet the user's heating demand.

[0051] Third, to achieve the rapid heating function.

[0052] When the unit receives the rapid heating instruction, taking the rapid cooling instruction as an example, both the first heat pump main unit 31 and the second heat pump main unit 33 turn on the cooling mode. If the first three-way valve 41 and the second three-way valve 42 are both in the first working position, the cold water from the first heat pump main unit 31 and the second heat pump main unit 33 simultaneously enter the buffer water tank 11. After the heating water pump 15 is turned on, the water enters the heat exchange component 13, and the rapid cooling demand can be met; when receiving the rapid heating instruction, both the first heat pump main unit 31 and the second heat pump main unit 33 turn on the heating mode, and the working process is the same as that of the rapid cooling instruction, and the rapid heating function can be achieved.

[0053] Fourth, to achieve the rapid hot water supply function.

[0054] When the unit receives the rapid hot water supply instruction, the first heat pump main unit 31 and the second heat pump main unit 33 turn on the heating mode. If the first three-way valve 41 and the second three-way valve 42 are both in the second working position, the cold water from the first heat pump main unit 31 and the second heat pump main unit 33 simultaneously enter the domestic hot water tank 20, and the rapid hot water supply function can be achieved.

[0055] It should be noted that the number of heat pump hosts can be three, four, etc., and can be reasonably designed according to needs; the number of control valves is the same as that of the heat pump hosts and is connected in one-to-one correspondence.

[0056] Based on the heat pump unit provided in any of the above embodiments, an embodiment of the present invention provides a control method for a heat pump unit, as Figure 2 shown, the control method includes the following steps: Step 100, obtain a work instruction.

[0057] Step 200, based on the work instruction, control the control valve to act so that the heat pump unit is in the operating mode corresponding to the work instruction.

[0058] It can be understood that obtaining the work instruction of the heat pump unit, the work instruction can include a heating and hot water production instruction, a heating instruction, and a hot water production instruction; and based on the work instruction, control the action of the control valve. The control valve has a first working position and a second working position. When the control valve is in the first working position, the heat pump host is connected to the heating system 10 through the control valve, and the water of the heat pump host enters the heating system 10 through the control valve to achieve the heating function; when the control valve is in the second working position, the heat pump host is connected to the hot water tank 20 through the control valve, the heat pump host turns on the heating mode, and the hot water of the heat pump host enters the hot water tank 20 through the control valve to achieve the hot water production function; thus, by switching the control valve between the first working position and the second working position, the switching between the heating function and the hot water production function can be realized.

[0059] The heat pump system 30 includes multiple heat pump hosts, and multiple heat pump hosts correspond to multiple control valves. Some control valves are in the first working position, and the rest of the control valves are in the second working position. Then, the heat pump hosts connected to the control valves in the first working position are connected to the heating system 10 to achieve the heating function, and the heat pump hosts connected to the control valves in the second working position are connected to the hot water tank 20 to achieve the hot water production function. Thus, the heating function and the hot water production function can be realized simultaneously by multiple heat pump hosts.

[0060] Optionally, when the work instruction is a heating and hot water production instruction, step 200, based on the work instruction, control the control valve to act, specifically including the following content: Based on the heating and hot water production instruction, control at least one control valve to be in the first working position and the rest of the control valves to be in the second working position.

[0061] It can be understood that, based on the heating and hot water production instruction, at least one control valve is controlled to be in the first working position, and the remaining control valves are in the second working position. The control valve in the first working position is denoted as control valve A, and the heat pump main unit connected to control valve A is denoted as heat pump main unit A; the control valve in the second working position is denoted as control valve B, and the heat pump main unit connected to control valve B is denoted as heat pump main unit B. Then, heat pump main unit A is turned on to realize the heating function, and heat pump main unit B is turned on to realize the hot water production function, so as to simultaneously realize the refrigeration and hot water production functions.

[0062] It should be noted that if the heating is in the heating mode, then heat pump main unit A is in the heating mode; if the heating is in the cooling mode, then heat pump main unit A is in the cooling mode.

[0063] Exemplarily, the heating and hot water production instruction includes a heating instruction and a hot water production instruction, and the heating instruction includes a heating instruction and a cooling instruction; taking the cooling instruction as an example, after receiving the cooling instruction, heat pump main unit A turns on the cooling mode; after receiving the hot water production instruction, heat pump main unit B turns on the heating mode, and heat pump main unit B quickly increases the frequency to meet the user's hot water demand, so as to simultaneously realize the refrigeration and hot water production functions.

[0064] It should be noted that when the heating is in the heating mode, the heating and hot water production instruction is a heating and hot water production instruction; when the heating is in the cooling mode, the heating and hot water production instruction is a cooling and hot water production instruction.

[0065] Optionally, when the working instruction is a heating instruction, step 200, based on the working instruction, controls the control valve to act, which specifically includes the following content: Based on the heating instruction, control all control valves to be in the first working position.

[0066] It can be understood that when the unit receives a rapid heating instruction, taking the rapid cooling instruction as an example, both the first heat pump main unit 31 and the second heat pump main unit 33 turn on the cooling mode, and both the first three-way valve 41 and the second three-way valve 42 are in the first working position. Then, the cold water of the first heat pump main unit 31 and the second heat pump main unit 33 simultaneously enters the buffer water tank 11. After the heating water pump 15 is turned on, the water enters the heat exchange element 13, and the rapid cooling demand can be realized.

[0067] Optionally, when the working instruction is a hot water production instruction, step 200, based on the working instruction, controls the control valve to act, which specifically includes the following content: Based on the hot water production instruction, control all control valves to be in the second working position.

[0068] It can be understood that when the unit receives a fast hot water production instruction, the first heat pump main unit 31 and the second heat pump main unit 33 are turned on to the heating mode, and both the first three-way valve 41 and the second three-way valve 42 are in the second working position. Then, the cold water of the first heat pump main unit 31 and the second heat pump main unit 33 simultaneously enters the domestic hot water tank 20, and the function of fast hot water production can be achieved.

[0069] Further, as Figure 3 shown, the control method of this embodiment further includes the steps: Step 300, obtain the current temperature of the hot water tank 20.

[0070] Step 400, when the current temperature is greater than or equal to the temperature threshold, control the control valve in the second working position to switch from the second working position to the first working position.

[0071] It can be understood that when the working instruction is a heating and hot water production instruction or a hot water production instruction, by obtaining the current temperature of the hot water tank 20, the current temperature represents the water temperature in the hot water tank 20. When the current temperature is greater than or equal to the temperature threshold, the control valve B is switched from the second working position to the first working position, and the heat pump main unit B corresponding to the control valve B is connected to the buffer water tank 11 through the control valve B to provide heating requirements for users.

[0072] Next, the control device of the heat pump unit provided by the present invention will be described. The control device of the heat pump unit described below can be mutually referred to the control method of the heat pump unit described above.

[0073] An embodiment of the present invention further provides a control device of a heat pump unit. As Figure 4 shown, the control device includes a first acquisition module 410 and a first control module 420; wherein: The first acquisition module 410 is used to acquire a working instruction, and the working instruction includes a heating and hot water production instruction, a heating instruction, and a hot water production instruction; The first control module 420 is used to control the action of the control valve based on the working instruction so that the heat pump unit is in the operating mode corresponding to the working instruction.

[0074] In some embodiments, the control device further includes a second acquisition module and a second control module; wherein: The second acquisition module is used to acquire the current temperature of the hot water tank.

[0075] The second control module is used to control the control valve in the second working position to switch from the second working position to the first working position when the current temperature is greater than or equal to the temperature threshold.

[0076] Figure 5 An example of a schematic physical structure diagram of an electronic device is shown in Figure 5As shown in the figure, the electronic device may include: a processor 510, a communications interface 520, a memory 530, and a communication bus 540. Among them, the processor 510, the communications interface 520, and the memory 530 communicate with each other through the communication bus 540. The processor 510 can call the logical instructions in the memory 530 to execute the control method of the heat pump unit.
