Description

Technical Field

[0001] This invention relates to the field of heat pump technology, and more specifically, to a control method, control device, computer-readable storage medium, and air source heat pump system for an air source heat pump. Background Technology

[0002] As people's living standards improve, consumers have higher requirements for the cooling / heating speed of air source heat pumps. To improve the heating output and temperature rise rate of air source heat pumps, the industry common practice is to place an electric heating element after the heat exchanger along the direction of ventilation to assist in increasing heat. The drawback of this approach is that in heating mode, the ventilation air has already been heated once after passing through the heat exchanger, and its temperature has risen. When it passes through the electric heating element, the heat from the electric heater is not carried away in time, causing the electric heating element to activate its internal protection mechanism. This results in the electric heating element not performing optimally, thus reducing the overall performance of the unit. Summary of the Invention

[0011] According to another aspect of this application, a control device for an air source heat pump is provided. The air source heat pump includes an air inlet, an electric heater, and a heat exchanger. The electric heater is located between the air inlet and the heat exchanger. The angle between the heating surface of the electric heater and the horizontal direction is adjustable. The heating surface is the surface of the electric heater that heats the air entering through the air inlet. The device includes: a control unit for executing a control step, controlling the air source heat pump to start, causing the electric heater and the heat exchanger to begin operation; an acquisition unit for executing an acquisition step, acquiring an indoor ambient temperature and a heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger; and an adjustment unit for executing an adjustment step, adjusting a target angle according to the indoor ambient temperature and the heat exchanger temperature, such that the target angle is positively correlated with both the indoor ambient temperature and the heat exchanger temperature, wherein the target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°.

[0012] According to another aspect of this application, a computer-readable storage medium is provided, the computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device on which the computer-readable storage medium is located to perform any of the methods described.

[0013] According to another aspect of this application, an air source heat pump system is provided, comprising: an air source heat pump, one or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including methods for performing any one of the methods described.

[0014] Applying the technical solution of this application, in the control method of the air source heat pump described above, firstly, a control step is executed to control the air source heat pump to start, so that the electric heater and the heat exchanger begin to operate; then, an acquisition step is executed to acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger; finally, an adjustment step is executed to adjust the target angle according to the indoor ambient temperature and the heat exchanger temperature, such that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature, wherein the target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°. The electric heater of the air source heat pump is located between the air inlet and the heat exchanger, which reduces the temperature of the incoming air, improves heat dissipation, increases the heat output of the electric heater, and enhances the performance utilization rate of the electric heating device. The angle between the heating surface of the electric heater and the horizontal direction can also be adjusted to regulate the heat dissipation and ventilation volume of the electric heater. Specifically, the heat dissipation of the electric heater is adjusted by the target angle. The lower the indoor ambient temperature, the lower the heat exchanger temperature, and the greater the demand for electric auxiliary heating. Adjusting the target angle to be smaller increases the air resistance, resulting in more heat dissipation from the electric heater and improved heating performance. Conversely, the higher the indoor ambient temperature, the higher the heat exchanger temperature, and the lower the demand for electric auxiliary heating. Adjusting the target angle to be larger reduces the air resistance, resulting in less heat dissipation from the electric heater and lower energy consumption. This allows the heat exchanger's heating performance to be fully utilized, solving the problem of poor heating performance in existing air source heat pump technologies. Attached Figure Description

[0031] This embodiment provides a control method for an air source heat pump operating on a mobile terminal, computer terminal, or similar computing device, wherein, as Figure 2As shown, the air source heat pump includes an air inlet, an electric heater 10, and a heat exchanger 20. The electric heater 10 is located between the air inlet and the heat exchanger 20. The angle between the heating surface of the electric heater 10 and the horizontal direction is adjustable. The heating surface is the surface of the electric heater that heats the air entering through the air inlet. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] Figure 3 This is a flowchart of a control method for an air-source heat pump according to an embodiment of this application. Figure 3 As shown, the method includes the following steps:

[0033] Step S201, control step, control the air source heat pump to start, so that the electric heater and the heat exchanger start to operate;

[0034] Specifically, when the air source heat pump is started, the electric heater and the heat exchanger start operating simultaneously to provide heating, thereby achieving rapid heating and ensuring comfort.

[0035] Step S202, the acquisition step, acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger.

[0036] Specifically, the indoor unit is equipped with an indoor ambient temperature sensor to detect the indoor ambient temperature T in real time. 内环 The heat exchanger temperature sensor monitors the heat exchanger temperature in real time. 内管 .

[0037] Step S203, adjustment step, adjust the target angle according to the indoor ambient temperature and the heat exchanger temperature, so that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature respectively. The target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°.

[0038] Specifically, t 内管 This indicates the heat output capacity of the heat pump system, T. 内环This indicates the degree of heat demand from the ambient temperature. The heat dissipation of the heat exchanger is adjusted by changing the target angle, so that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature. In cooling mode, the electric heater does not need to work. At this time, the electric heating device is parallel to the ventilation direction to reduce wind resistance and maximize ventilation. In heating mode, the ventilation needs to pass through the electric heater first and then through the heat exchanger. At this time, the angle of the electric heating device needs to be adjusted according to the indoor ambient temperature and the heat exchanger temperature to achieve variable ventilation. In addition, the electric input of the electric heater can be adjusted according to the indoor load requirements and the heat output of the air source heat pump itself, and promote the rapid heat generation of the heat pump.

[0039] In the above-mentioned control method for the air source heat pump, firstly, a control step is executed to start the air source heat pump, causing the electric heater and the heat exchanger to start operating; then, an acquisition step is executed to acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger; finally, an adjustment step is executed to adjust the target angle according to the indoor ambient temperature and the heat exchanger temperature, such that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature, wherein the target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°. The electric heater of the air source heat pump is located between the air inlet and the heat exchanger, which reduces the temperature of the incoming air, improves heat dissipation, increases the heat output of the electric heater, and enhances the performance utilization rate of the electric heating device. The angle between the heating surface of the electric heater and the horizontal direction can also be adjusted to regulate the heat dissipation and ventilation volume of the electric heater. Specifically, the heat dissipation of the electric heater is adjusted by the target angle. The lower the indoor ambient temperature, the lower the heat exchanger temperature, and the greater the demand for electric auxiliary heating. Adjusting the target angle to be smaller increases the air resistance, resulting in more heat dissipation from the electric heater and improved heating performance. Conversely, the higher the indoor ambient temperature, the higher the heat exchanger temperature, and the lower the demand for electric auxiliary heating. Adjusting the target angle to be larger reduces the air resistance, resulting in less heat dissipation from the electric heater and lower energy consumption. This allows the heat exchanger's heating performance to be fully utilized, solving the problem of poor heating performance in existing air source heat pump technologies.

[0040] Furthermore, after the airflow passes through the electric heating device, its temperature rises. When it passes through the heat exchanger, compared to traditional methods, the inlet air temperature is higher, which promotes a rise in the high pressure of the air source heat pump system, increasing the outlet air temperature. This also indirectly leads to an increase in the system's low operating pressure and a higher refrigerant evaporation temperature, indirectly reducing frost buildup on the outdoor heat exchanger, extending the unit's effective heating time, and improving its overall heating performance. The heating capacity of the air source heat pump system changes with increasing inlet air temperature at the same air volume as shown below. Figure 4 As shown.

[0041] The aforementioned electric heater can be a PTC (Positive Temperature Coefficient) thermistor. PTC heating elements are ceramic thermistors with a positive temperature coefficient, and can be manufactured in various shapes to suit different applications. With the continuous upgrading of the air conditioning market, ceramic PTCs, with their unique performance advantages, have replaced tubular electric heaters as the mainstream heating element for air conditioners. Figure 5 As shown, its characteristic is that when the ambient temperature T decreases, the power of the PTC electric heater increases, and the surface temperature also increases accordingly; conversely, when the ambient temperature T increases, its power decreases, and the surface temperature also decreases accordingly. Its heat generation can be automatically adjusted according to changes in ambient temperature. Based on this principle, in the design, the heat dissipation can be increased by reducing the temperature of the ventilation airflow or increasing the air velocity, thereby reducing the surface temperature of the heating element and increasing the power and heat generation.

[0042] To improve heating performance, in one optional embodiment, step S203 includes at least:

[0043] Step S2031: When the indoor ambient temperature meets the first condition, control the air source heat pump to adjust the target angle to the first angle range. The first condition is that the indoor ambient temperature is less than or equal to the first temperature threshold.

[0044] Step S2032: When the indoor ambient temperature meets the second condition, control the air source heat pump to adjust the target angle to the second angle range. The minimum value of the second angle range is greater than the maximum value of the first angle range. The second condition is that the indoor ambient temperature is greater than the first temperature threshold and less than the second temperature threshold.

[0045] Step S2033: When the indoor ambient temperature meets the third condition, control the air source heat pump to adjust the target angle to the third angle range. The minimum value of the third angle range is greater than the maximum value of the second angle range. The third condition is that the indoor ambient temperature is greater than or equal to the second temperature threshold.

[0046] Specifically, the indoor ambient temperature is divided into three zones: a low-temperature zone, a medium-temperature zone, and a high-temperature zone. The boundary thresholds are the first temperature threshold T1 and the second temperature threshold T2. The indoor ambient temperature is located in the low-temperature zone, i.e., the aforementioned indoor ambient temperature T... 内环 If the indoor temperature is less than or equal to the first temperature threshold T1, the indoor temperature is low and the heating demand is high. The target angle is adjusted to the first angle range to increase wind resistance, increase the ventilation volume through which the electric heating energy is generated, increase the heat dissipation of the electric heating energy, and increase the output power of the electric heater. The indoor ambient temperature is then in the medium temperature range, i.e., the aforementioned indoor ambient temperature T1. 内环If the indoor temperature is greater than the first temperature threshold T1 and less than the second temperature threshold T2, the indoor temperature is generally moderate and the heating demand is not high. Adjusting the target angle to the second angle range reduces wind resistance, decreases heat dissipation from the electric heater, and reduces the output power of the electric heater, thus saving energy. The indoor ambient temperature is now in the high-temperature zone, i.e., the aforementioned indoor ambient temperature T... 内环 If the temperature is greater than or equal to the second temperature threshold T2 mentioned above, the indoor temperature is high and the heating demand is low. Adjusting the target angle to the third angle range will greatly reduce wind resistance, greatly reduce the heat dissipation of electric heating, greatly reduce the output power of electric heater, and even stop electric auxiliary heating. Increasing the ventilation of the heat exchanger will allow the heat exchanger to perform its heating function and meet the demand.

[0047] To further improve heating performance, in one optional embodiment, step S2031 includes:

[0048] Step S20311: When the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fourth condition, control the air source heat pump to adjust the target angle to the first angle. The first angle is within the first angle range. The fourth condition is that the heat exchanger temperature is less than or equal to the third temperature threshold.

[0049] Step S20312: When the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fifth condition, control the air source heat pump to adjust the target angle to the second angle. The second angle is within the range of the first angle and is greater than the first angle. The fifth condition is that the heat exchanger temperature is greater than the third temperature threshold and less than the fourth temperature threshold.

[0050] Step S20313: When the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the sixth condition, control the air source heat pump to adjust the target angle to a third angle. The third angle is within the first angle range and is greater than the second angle. The sixth condition is that the heat exchanger temperature is greater than or equal to the fourth temperature threshold.

[0051] Specifically, when the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fourth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管 Less than or equal to the third temperature threshold t1, i.e., T 内环 ≤T1 and t 内管When ≤t1, the target angle is adjusted to the first angle β1. The indoor temperature is low, the heat pump system builds up high pressure slowly, the heat exchanger temperature is also low, and the heat output is severely insufficient. At this time, the electric heater needs to have the maximum output power. Under the condition that the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fifth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管 The temperature is greater than the third temperature threshold t1 and less than the fourth temperature threshold t2, i.e., T 内环 ≤T1 and t1<t 内管 When the temperature is less than t2, the target angle is adjusted to the second angle β2. The indoor temperature is low, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output some heat. At this time, the ventilation volume through electric heating can be reduced, the power of the electric heater can be reduced, and low-efficiency energy consumption can be reduced. When the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the sixth condition, the indoor ambient temperature T is reduced. 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管 Greater than or equal to the fourth temperature threshold t2, i.e., T 内环 ≤T1 and t 内管 When ≥t2, the target angle is adjusted to the second angle β3. The indoor temperature is low, but the heat pump heat exchanger has reached a high temperature. At this time, the angle needs to be increased to reduce the wind resistance formed by the electric heater and release the heat of the heat pump system first. Only a small amount of electric heating is needed to supplement or the electric heating can be turned off to meet the comfort requirements.

[0052] To further improve heating performance, in one optional embodiment, step S2032 includes:

[0053] Step S20321: When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fourth condition, control the air source heat pump to adjust the target angle to the fourth angle. The fourth angle is within the second angle range. The fourth condition is that the heat exchanger temperature is less than or equal to the third temperature threshold.

[0054] Step S20322: When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fifth condition, control the air source heat pump to adjust the target angle to the fifth angle. The fifth angle is within the second angle range and is greater than the fourth angle. The fifth condition is that the heat exchanger temperature is greater than the third temperature threshold and less than the fourth temperature threshold.

[0055] Step S20323: When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the sixth condition, control the air source heat pump to adjust the target angle to the sixth angle. The sixth angle is within the second angle range and is greater than the fifth angle. The sixth condition is that the heat exchanger temperature is greater than or equal to the fourth temperature threshold.

[0056] Specifically, when the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fourth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 Less than or equal to the third temperature threshold t1, i.e., T1 < T 内环 <T2 and t 内管 When ≤t1, the target angle is adjusted to the fourth angle β4. The indoor temperature is generally normal. The heat pump system needs a certain amount of time to establish high pressure and increase the outlet air temperature. At this time, electric heating is needed to supplement heat and assist the heat pump system in establishing high pressure as soon as possible. When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fifth condition, the indoor ambient temperature T is made to meet the second condition. 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 The temperature is greater than the third temperature threshold t1 and less than the fourth temperature threshold t2, i.e., T1 < T 内环 <T2 and t1<t 内管 When <t2, the target angle is adjusted to the fifth angle β5. The indoor temperature is generally normal, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output a significant amount of heat and provide a comfortable outlet air temperature. At this point, the ventilation volume through electric heating can be reduced, the power of the electric heater can be decreased, and low-efficiency energy consumption can be reduced. When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the sixth condition, the indoor ambient temperature T... 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 Greater than or equal to the fourth temperature threshold t2, i.e., T1 < T 内环 <T2 and t 内管 When ≥t2, the above target angle is adjusted to the sixth angle β6. The indoor temperature is generally normal, but the heat pump heat exchanger has already reached a high temperature. At this time, it is necessary to increase the angle to reduce the wind resistance formed by the electric heater and prioritize the release of heat from the heat pump system. Only a small amount of electric heating is needed to supplement or the electric heating can be turned off to meet the comfort requirements.

[0057] To further improve heating performance, in one optional embodiment, step S2033 includes:

[0058] Step S20331: When the indoor ambient temperature meets the third condition, control the air source heat pump to adjust the target angle to the seventh angle and control the electric heater to turn off. The seventh angle is located within the third angle range.

[0059] Specifically, when the aforementioned indoor ambient temperature meets the third condition, the aforementioned indoor ambient temperature T is made to... 内环 Greater than or equal to the second temperature threshold T2 mentioned above, i.e., T 内环 When T2 is greater than or equal to β, the aforementioned target angle is adjusted to β. max If the indoor temperature is slightly high, a normal heat pump system can quickly establish high pressure and provide sufficient heat. At this time, electric heating is not required, and the aforementioned electric heater should be turned off.

[0060] Of course, this applies when the indoor ambient temperature meets the third condition mentioned above, i.e., the indoor ambient temperature T. 内环 The third angle range can also be selected as three angles β7, β8, and β9, which are greater than or equal to the second temperature threshold T2 mentioned above. These angles correspond to the three temperature ranges of the heat exchanger in the heating room: low temperature, medium temperature, and high temperature. Among them, β7 < β8 < β9, that is, t 内管 When t1 ≤ t2, the included angle of the above target is adjusted to the eighth angle β7, and when t1 < t2. 内管 When <t2, the aforementioned target angle is adjusted to the ninth angle β8, t 内管 When ≥t2, the target angle is adjusted to the tenth angle β9, and the heat dissipation of the electric heater is gradually reduced, which can meet the needs of comfort.

[0061] To further improve heating performance, in an optional embodiment, after step S203, the method further includes:

[0062] Step S301: Repeat the above acquisition step and the above adjustment step at least once until the air source heat pump stops.

[0063] Specifically, indoor ambient temperature T 内环 and heat exchanger temperature t 内管 It changes in real time; the indoor unit is equipped with an indoor ambient temperature sensor to detect the indoor ambient temperature (T) in real time. 内环 The heat exchanger temperature sensor monitors the heat exchanger temperature in real time. 内管 Indoor ambient temperature T at different times 内环 and heat exchanger temperature t 内管 The indoor ambient temperature T may be in different temperature ranges, therefore, each time the indoor ambient temperature T is measured...内环 and heat exchanger temperature t 内管 Repeat the above adjustment steps once. For example, in the low-temperature zone of the indoor environment, when the motor angle is β2, the airflow of the heat exchanger increases due to the reduced wind resistance, which will cause the heat exchanger temperature to drop. If t 内管 When the temperature drops below t1, the motor angle returns to β1. As the indoor temperature rises, T... 环 When the range changes, the motor angle moves synchronously to the new range until the air source heat pump stops.

[0064] To achieve precise adjustment of the target angle, one optional implementation method is as follows: Figure 2 As shown, the air source heat pump also includes a rotary motor 30, which is connected to the electric heater 10. The rotary motor 30 is used to drive the electric heater 10 to rotate. Step S20331 includes:

[0065] Step S203311: Control the rotary motor to rotate to a predetermined angle corresponding to the seventh angle, so that the electric heater rotates to a predetermined position, the predetermined position being the position of the electric heater when the target included angle is the seventh angle.

[0066] Specifically, the aforementioned rotary motor drives the aforementioned electric heater to rotate, and the rotation angle of the aforementioned rotary motor corresponds one-to-one with the rotation angle of the aforementioned electric heater. By controlling the aforementioned rotary motor to rotate to the predetermined angle corresponding to the aforementioned seventh angle, the aforementioned target included angle can be adjusted to the seventh angle, and the aforementioned electric heater can rotate to the predetermined position. The same applies to other angles.

[0067] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the air source heat pump control method of this application will be described in detail below with reference to specific embodiments.

[0068] This embodiment relates to a specific control method for an air source heat pump, such as... Figure 6 As shown, it includes the following steps:

[0069] Step S1: Set the indoor unit to use an indoor ambient temperature sensor to monitor the indoor ambient temperature T in real time. 环 The heat exchanger temperature sensor monitors the heat exchanger temperature in real time. 内管 The electric heating device is controlled by a rotating motor to adjust its angle.

[0070] Step S2: The electric heater drive motor adjusts its angle based on the current actual indoor ambient temperature and heat exchanger temperature, combined with relevant preset thresholds in the program. In the preset control program parameters, the indoor ambient temperature is divided into three zones: low temperature, medium temperature, and high temperature, with threshold values ​​T1 and T2, where T1 < T2; the indoor heat exchanger temperature is also divided into three zones: low temperature, medium temperature, and high temperature, with threshold values ​​t1 and t2, where t1 < t2; the rotation angles of the electric heating element are β1, β2, ... β... max And they increase sequentially. The program's control method is as follows: when the unit receives a non-heating mode start-up command, the rotary motor directly runs to the maximum angle βmax;

[0071] Step S3: If a heating mode start command is received, first check the current indoor ambient temperature T. 环 Heat exchanger temperature t 内管 Then, the execution logic is as follows: [Low-temperature zone in indoor environment]

[0072] T 内环 ≤T1, and t 内管 When ≤t1, the target angle is adjusted to angle β1. Explanation: When the indoor temperature is low, the heat pump system builds up high pressure slowly, the heat exchanger temperature is also low, and the heat output is seriously insufficient. At this time, the electric heater needs to output maximum power.

[0073] T 内环 ≤T1, and t1<t 内管 When the temperature is less than t2, the target angle is adjusted to angle β2. Explanation: The indoor temperature is low, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output some heat. At this point, the ventilation volume through electric heating can be reduced, the power of the electric heater can be decreased, and low-efficiency energy consumption can be reduced.

[0074] T 内环 ≤T1, and t 内管 When ≥t2, the target angle is adjusted to angle β3. Explanation: The indoor temperature is low, but the heat pump heat exchanger has already reached a high temperature. At this time, it is necessary to increase the angle to reduce the wind resistance formed by the electric heater, and prioritize the release of heat from the heat pump system. Only a small amount of electric heating is needed to supplement or the electric heating can be turned off to meet the comfort requirements.

[0075] [Indoor ambient temperature in the medium temperature range]

[0076] T1 < T 内环 <T2, and t 内管 When ≤t1, the target angle is adjusted to β4. Note: The indoor temperature is generally normal. The heat pump system needs time to establish high pressure and raise the outlet air temperature. During this time, electric heating is required to supplement heat and assist the heat pump system in establishing high pressure as quickly as possible.

[0077] T1 < T 内环 <T2, t1<t 内管 When <t2, the target angle is adjusted to β5. Explanation: The indoor temperature is generally normal, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output a significant amount of heat and provide a comfortable outlet air temperature. At this point, the ventilation volume through electric heating can be reduced, the power of the electric heater can be decreased, and low-efficiency energy consumption can be reduced.

[0078] T1 < T 内环 <T2, and t 内管 When ≥t2, the target angle is adjusted to β6. Explanation: The indoor temperature is generally low, but the heat pump heat exchanger has already reached a high temperature. At this time, it is necessary to increase the angle to reduce the wind resistance formed by the electric heater, prioritize the release of heat from the heat pump system, and only require a small amount of electric heating to supplement or turn off the electric heating to meet the comfort requirements.

[0079] [High-temperature zone in indoor environment]

[0080] T 内环 When T2 is greater than or equal to β, the target angle is adjusted to β. max Note: When the indoor temperature is slightly high, a normal heat pump system can quickly establish high pressure and provide sufficient heat, at which point electric heating is not required.

[0081] Step S4: Repeat step S3 until the air source heat pump stops.

[0082] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0083] This application also provides a control device for an air source heat pump. It should be noted that the control device for the air source heat pump in this application can be used to execute the control method for the air source heat pump provided in this application. For example... Figure 2 As shown, the air source heat pump includes an air inlet, an electric heater 10, and a heat exchanger 20. The electric heater 10 is located between the air inlet and the heat exchanger 20. The angle between the heating surface of the electric heater 10 and the horizontal direction is adjustable. The heating surface is the surface of the electric heater that heats the air entering through the air inlet. This device is used to implement the above embodiments and preferred embodiments, and details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0084] The control device for the air source heat pump provided in the embodiments of this application is described below.

[0085] Figure 7 This is a structural block diagram of the control device for an air source heat pump according to an embodiment of this application. Figure 7 As shown, the device includes:

[0086] The control unit 100 is used to execute control steps to control the air source heat pump to start, so that the electric heater and the heat exchanger start to operate.

[0087] Specifically, when the air source heat pump is started, the electric heater and the heat exchanger start operating simultaneously to provide heating, thereby achieving rapid heating and ensuring comfort.

[0088] The acquisition unit 200 is used to perform the acquisition step to acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger.

[0089] Specifically, the indoor unit is equipped with an indoor ambient temperature sensor to detect the indoor ambient temperature T in real time. 内环 The heat exchanger temperature sensor monitors the heat exchanger temperature in real time. 内管 .

[0090] The adjustment unit 300 is used to perform the adjustment steps, adjusting the target angle according to the indoor ambient temperature and the heat exchanger temperature, so that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature, respectively. The target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°.

[0091] Specifically, t 内管 This indicates the heat output capacity of the heat pump system, T. 内环 This indicates the degree of heat demand from the ambient temperature. The heat dissipation of the heat exchanger is adjusted by changing the target angle, so that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature. In cooling mode, the electric heater does not need to work. At this time, the electric heating device is parallel to the ventilation direction to reduce wind resistance and maximize ventilation. In heating mode, the ventilation needs to pass through the electric heater first and then through the heat exchanger. At this time, the angle of the electric heating device needs to be adjusted according to the indoor ambient temperature and the heat exchanger temperature to achieve variable ventilation. In addition, the electric input of the electric heater can be adjusted according to the indoor load requirements and the heat output of the air source heat pump itself, and promote the rapid heat generation of the heat pump.

[0092] In the control device of the aforementioned air source heat pump, the control unit executes a control step to start the air source heat pump, causing the electric heater and the heat exchanger to start operating; the acquisition unit executes an acquisition step to acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger; the adjustment unit executes an adjustment step to adjust the target angle according to the indoor ambient temperature and the heat exchanger temperature, such that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature, wherein the target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°. The electric heater of the air source heat pump is located between the air inlet and the heat exchanger, which reduces the temperature of the incoming air, improves heat dissipation, increases the heat output of the electric heater, and enhances the performance utilization rate of the electric heating device. The angle between the heating surface of the electric heater and the horizontal direction can also be adjusted to regulate the heat dissipation and ventilation volume of the electric heater. Specifically, the heat dissipation of the electric heater is adjusted by the target angle. The lower the indoor ambient temperature, the lower the heat exchanger temperature, and the greater the demand for electric auxiliary heating. Adjusting the target angle to be smaller increases the air resistance, resulting in more heat dissipation from the electric heater and improved heating performance. Conversely, the higher the indoor ambient temperature, the higher the heat exchanger temperature, and the lower the demand for electric auxiliary heating. Adjusting the target angle to be larger reduces the air resistance, resulting in less heat dissipation from the electric heater and lower energy consumption. This allows the heat exchanger's heating performance to be fully utilized, solving the problem of poor heating performance in existing air source heat pump technologies.

[0093] Furthermore, after the airflow passes through the electric heating device, its temperature rises. When it passes through the heat exchanger, compared to traditional methods, the inlet air temperature is higher, which promotes a rise in the high pressure of the air source heat pump system, increasing the outlet air temperature. This also indirectly leads to an increase in the system's low operating pressure and a higher refrigerant evaporation temperature, indirectly reducing frost buildup on the outdoor heat exchanger, extending the unit's effective heating time, and improving its overall heating performance. The heating capacity of the air source heat pump system changes with increasing inlet air temperature at the same air volume as shown below. Figure 4 As shown.

[0094] The aforementioned electric heater can be a PTC (Positive Temperature Coefficient) thermistor. PTC heating elements are ceramic thermistors with a positive temperature coefficient, and can be manufactured in various shapes to suit different applications. With the continuous upgrading of the air conditioning market, ceramic PTCs, with their unique performance advantages, have replaced tubular electric heaters as the mainstream heating element for air conditioners. Figure 5As shown, its characteristic is that when the ambient temperature T decreases, the power of the PTC electric heater increases, and the surface temperature also increases accordingly; conversely, when the ambient temperature T increases, its power decreases, and the surface temperature also decreases accordingly. Its heat generation can be automatically adjusted according to changes in ambient temperature. Based on this principle, in the design, the heat dissipation can be increased by reducing the temperature of the ventilation airflow or increasing the air velocity, thereby reducing the surface temperature of the heating element and increasing the power and heat generation.

[0095] To improve heating performance, in one optional embodiment, the adjustment unit includes at least:

[0096] The first control module is used to control the air source heat pump to adjust the target angle to a first angle range when the indoor ambient temperature meets the first condition. The first condition is that the indoor ambient temperature is less than or equal to a first temperature threshold.

[0097] The second control module is used to control the air source heat pump to adjust the target angle to a second angle range when the indoor ambient temperature meets the second condition. The minimum value of the second angle range is greater than the maximum value of the first angle range. The second condition is that the indoor ambient temperature is greater than the first temperature threshold and less than the second temperature threshold.

[0098] The third control module is used to control the air source heat pump to adjust the target angle to a third angle range when the indoor ambient temperature meets the third condition. The minimum value of the third angle range is greater than the maximum value of the second angle range. The third condition is that the indoor ambient temperature is greater than or equal to the second temperature threshold.

[0099] Specifically, the indoor ambient temperature is divided into three zones: a low-temperature zone, a medium-temperature zone, and a high-temperature zone. The boundary thresholds are the first temperature threshold T1 and the second temperature threshold T2. The indoor ambient temperature is located in the low-temperature zone, i.e., the aforementioned indoor ambient temperature T... 内环 If the indoor temperature is less than or equal to the first temperature threshold T1, the indoor temperature is low and the heating demand is high. The target angle is adjusted to the first angle range to increase wind resistance, increase the ventilation volume through which the electric heating energy is generated, increase the heat dissipation of the electric heating energy, and increase the output power of the electric heater. The indoor ambient temperature is then in the medium temperature range, i.e., the aforementioned indoor ambient temperature T1. 内环 If the indoor temperature is greater than the first temperature threshold T1 and less than the second temperature threshold T2, the indoor temperature is generally moderate and the heating demand is not high. Adjusting the target angle to the second angle range reduces wind resistance, decreases heat dissipation from the electric heater, and reduces the output power of the electric heater, thus saving energy. The indoor ambient temperature is now in the high-temperature zone, i.e., the aforementioned indoor ambient temperature T... 内环If the temperature is greater than or equal to the second temperature threshold T2 mentioned above, the indoor temperature is high and the heating demand is low. Adjusting the target angle to the third angle range will greatly reduce wind resistance, greatly reduce the heat dissipation of electric heating, greatly reduce the output power of electric heater, and even stop electric auxiliary heating. Increasing the ventilation of the heat exchanger will allow the heat exchanger to perform its heating function and meet the demand.

[0100] To further improve heating performance, in one optional implementation, the first control module includes:

[0101] The first control submodule is used to control the air source heat pump to adjust the target angle to a first angle when the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fourth condition. The first angle is located within the first angle range, and the fourth condition is that the heat exchanger temperature is less than or equal to a third temperature threshold.

[0102] The second control submodule is used to control the air source heat pump to adjust the target angle to a second angle when the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fifth condition. The second angle is located within the first angle range and is greater than the first angle. The fifth condition is that the heat exchanger temperature is greater than the third temperature threshold and less than the fourth temperature threshold.

[0103] The third control submodule is used to control the air source heat pump to adjust the target angle to a third angle when the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the sixth condition. The third angle is located within the first angle range and is greater than the second angle. The sixth condition is that the heat exchanger temperature is greater than or equal to the fourth temperature threshold.

[0104] Specifically, when the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fourth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管 Less than or equal to the third temperature threshold t1, i.e., T 内环 ≤T1 and t 内管 When ≤t1, the target angle is adjusted to the first angle β1. The indoor temperature is low, the heat pump system builds up high pressure slowly, the heat exchanger temperature is also low, and the heat output is severely insufficient. At this time, the electric heater needs to have the maximum output power. Under the condition that the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the fifth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管The temperature is greater than the third temperature threshold t1 and less than the fourth temperature threshold t2, i.e., T 内环 ≤T1 and t1<t 内管 When the temperature is less than t2, the target angle is adjusted to the second angle β2. The indoor temperature is low, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output some heat. At this time, the ventilation volume through electric heating can be reduced, the power of the electric heater can be reduced, and low-efficiency energy consumption can be reduced. When the indoor ambient temperature meets the first condition and the heat exchanger temperature meets the sixth condition, the indoor ambient temperature T is reduced. 内环 The heat exchanger temperature t is less than or equal to the first temperature threshold T1. 内管 Greater than or equal to the fourth temperature threshold t2, i.e., T 内环 ≤T1 and t 内管 When ≥t2, the target angle is adjusted to the second angle β3. The indoor temperature is low, but the heat pump heat exchanger has reached a high temperature. At this time, the angle needs to be increased to reduce the wind resistance formed by the electric heater and release the heat of the heat pump system first. Only a small amount of electric heating is needed to supplement or the electric heating can be turned off to meet the comfort requirements.

[0105] To further improve heating performance, in one optional embodiment, the second control module includes:

[0106] The fourth control submodule is used to control the air source heat pump to adjust the target angle to the fourth angle when the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fourth condition. The fourth angle is within the second angle range, and the fourth condition is that the heat exchanger temperature is less than or equal to the third temperature threshold.

[0107] The fifth control submodule is used to control the air source heat pump to adjust the target angle to the fifth angle when the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fifth condition. The fifth angle is located within the second angle range and is greater than the fourth angle. The fifth condition is that the heat exchanger temperature is greater than the third temperature threshold and less than the fourth temperature threshold.

[0108] The sixth control submodule is used to control the air source heat pump to adjust the target angle to the sixth angle when the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the sixth condition. The sixth angle is located within the second angle range and is greater than the fifth angle. The sixth condition is that the heat exchanger temperature is greater than or equal to the fourth temperature threshold.

[0109] Specifically, when the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fourth condition, the indoor ambient temperature T is made to... 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 Less than or equal to the third temperature threshold t1, i.e., T1 < T 内环 <T2 and t 内管 When ≤t1, the target angle is adjusted to the fourth angle β4. The indoor temperature is generally normal. The heat pump system needs a certain amount of time to establish high pressure and increase the outlet air temperature. At this time, electric heating is needed to supplement heat and assist the heat pump system in establishing high pressure as soon as possible. When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the fifth condition, the indoor ambient temperature T is made to meet the second condition. 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 The temperature is greater than the third temperature threshold t1 and less than the fourth temperature threshold t2, i.e., T1 < T 内环 <T2 and t1<t 内管 When <t2, the target angle is adjusted to the fifth angle β5. The indoor temperature is generally normal, but the heat exchanger temperature has reached a certain level, high pressure has been established, and the heat pump itself can output a significant amount of heat and provide a comfortable outlet air temperature. At this point, the ventilation volume through electric heating can be reduced, the power of the electric heater can be decreased, and low-efficiency energy consumption can be reduced. When the indoor ambient temperature meets the second condition and the heat exchanger temperature meets the sixth condition, the indoor ambient temperature T... 内环 The heat exchanger temperature t is greater than the first temperature threshold T1 and less than the second temperature threshold T2. 内管 Greater than or equal to the fourth temperature threshold t2, i.e., T1 < T 内环 <T2 and t 内管 When ≥t2, the above target angle is adjusted to the sixth angle β6. The indoor temperature is generally normal, but the heat pump heat exchanger has already reached a high temperature. At this time, it is necessary to increase the angle to reduce the wind resistance formed by the electric heater and prioritize the release of heat from the heat pump system. Only a small amount of electric heating is needed to supplement or the electric heating can be turned off to meet the comfort requirements.

[0110] To further improve heating performance, in one optional implementation, the third control module includes:

[0111] The seventh control submodule is used to control the air source heat pump to adjust the target angle to the seventh angle and control the electric heater to turn off when the indoor ambient temperature meets the third condition. The seventh angle is located within the third angle range.

[0112] Specifically, when the aforementioned indoor ambient temperature meets the third condition, the aforementioned indoor ambient temperature T is made to... 内环 Greater than or equal to the second temperature threshold T2 mentioned above, i.e., T 内环 When T2 is greater than or equal to β, the aforementioned target angle is adjusted to β. max If the indoor temperature is slightly high, a normal heat pump system can quickly establish high pressure and provide sufficient heat. At this time, electric heating is not required, and the aforementioned electric heater should be turned off.

[0113] Of course, this applies when the indoor ambient temperature meets the third condition mentioned above, i.e., the indoor ambient temperature T. 内环 The third angle range can also be selected as three angles β7, β8, and β9, which are greater than or equal to the second temperature threshold T2 mentioned above. These angles correspond to the three temperature ranges of the heat exchanger in the heating room: low temperature, medium temperature, and high temperature. Among them, β7 < β8 < β9, that is, t 内管 When t1 ≤ t2, the included angle of the above target is adjusted to the eighth angle β7, and when t1 < t2. 内管 When <t2, the aforementioned target angle is adjusted to the ninth angle β8, t 内管 When ≥t2, the target angle is adjusted to the tenth angle β9, and the heat dissipation of the electric heater is gradually reduced, which can meet the needs of comfort.

[0114] To further improve heating performance, in one optional embodiment, the above-mentioned device further includes:

[0115] The repeating unit is used to repeat the acquisition step and the adjustment step at least once in sequence after adjusting the target angle according to the indoor ambient temperature and the heat exchanger temperature, until the air source heat pump stops.

[0116] Specifically, indoor ambient temperature T 内环 and heat exchanger temperature t 内管 It changes in real time; the indoor unit is equipped with an indoor ambient temperature sensor to detect the indoor ambient temperature (T) in real time. 内环 The heat exchanger temperature sensor monitors the heat exchanger temperature in real time. 内管 Indoor ambient temperature T at different times 内环 and heat exchanger temperature t 内管 The indoor ambient temperature T may be in different temperature ranges, therefore, each time the indoor ambient temperature T is measured... 内环 and heat exchanger temperature t 内管 Repeat the above adjustment steps once. For example, in the low-temperature zone of the indoor environment, when the motor angle is β2, the airflow of the heat exchanger increases due to the reduced wind resistance, which will cause the heat exchanger temperature to drop. If t 内管 When the temperature drops below t1, the motor angle returns to β1. As the indoor temperature rises, T... 环When the range changes, the motor angle moves synchronously to the new range until the air source heat pump stops.

[0117] To achieve precise adjustment of the target angle, one optional implementation method is as follows: Figure 2 As shown, the air source heat pump also includes a rotary motor 30, which is connected to the electric heater 10. The rotary motor 30 drives the electric heater 10 to rotate. The seventh control submodule includes:

[0118] The control subunit is used to control the rotary motor to rotate to a predetermined angle corresponding to the seventh angle, so that the electric heater rotates to a predetermined position, the predetermined position being the position of the electric heater when the target included angle is the seventh angle.

[0119] Specifically, the aforementioned rotary motor drives the aforementioned electric heater to rotate, and the rotation angle of the aforementioned rotary motor corresponds one-to-one with the rotation angle of the aforementioned electric heater. By controlling the aforementioned rotary motor to rotate to the predetermined angle corresponding to the aforementioned seventh angle, the aforementioned target included angle can be adjusted to the seventh angle, and the aforementioned electric heater can rotate to the predetermined position. The same applies to other angles.

[0120] The control device for the aforementioned air source heat pump includes a processor and a memory. The control unit, acquisition unit, and adjustment unit are all stored as program units in the memory, and the processor executes these program units to achieve the corresponding functions. All of the above modules reside in the same processor; alternatively, the modules may be located in different processors in any combination.

[0121] The processor contains a kernel, which retrieves the corresponding program unit from memory. One or more kernels can be configured, and adjusting kernel parameters can address the poor heating performance of existing air-source heat pumps.

[0150] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0151] 1) In the control method of the air source heat pump of this application, firstly, a control step is performed to control the air source heat pump to start, so that the electric heater and the heat exchanger start to operate; then, an acquisition step is performed to acquire the indoor ambient temperature and the heat exchanger temperature, wherein the indoor ambient temperature is the ambient temperature of the indoor space where the air source heat pump is located, and the heat exchanger temperature is the temperature of the heat exchanger; finally, an adjustment step is performed to adjust the target angle according to the indoor ambient temperature and the heat exchanger temperature, so that the target angle is positively correlated with the indoor ambient temperature and the heat exchanger temperature, wherein the target angle is the angle between the heating surface of the electric heater and the horizontal direction, and the target angle is less than or equal to 90°. The electric heater of the air source heat pump is located between the air inlet and the heat exchanger, which reduces the temperature of the incoming air, improves heat dissipation, increases the heat output of the electric heater, and enhances the performance utilization rate of the electric heating device. The angle between the heating surface of the electric heater and the horizontal direction can also be adjusted to regulate the heat dissipation and ventilation volume of the electric heater. Specifically, the heat dissipation of the electric heater is adjusted by the target angle. The lower the indoor ambient temperature, the lower the heat exchanger temperature, and the greater the demand for electric auxiliary heating. Adjusting the target angle to be smaller increases the air resistance, resulting in more heat dissipation from the electric heater and improved heating performance. Conversely, the higher the indoor ambient temperature, the higher the heat exchanger temperature, and the lower the demand for electric auxiliary heating. Adjusting the target angle to be larger reduces the air resistance, resulting in less heat dissipation from the electric heater and lower energy consumption. This allows the heat exchanger's heating performance to be fully utilized, solving the problem of poor heating performance in existing air source heat pump technologies.

The electric heater of the air source heat pump is located between the air inlet and the heat exchanger, which reduces the temperature of the incoming air, improves heat dissipation, increases the heat output of the electric heater, and enhances the performance utilization rate of the electric heating device.
