Description

Technical Field

[0001] This invention relates to the field of heat pump system control technology, specifically to an adaptive control method, device, and medium for the chassis heating element of a heat pump system. Background Technology

[0002] With the widespread application of heat pump systems, their reliable operation in extreme environments such as low temperature and high humidity has received increasing attention. In cold environments, condensate often accumulates on the heat pump chassis. When the ambient temperature drops below freezing, this condensate may freeze rapidly, causing the chassis to be covered with an ice layer. This ice layer not only affects the smooth drainage of the heat pump but can also increase the load on the compressor and other critical components, potentially causing equipment damage and shortening the system's lifespan. Therefore, in the design of heat pump systems, chassis heating elements are typically used to protect the chassis from ice.

[0003] However, existing chassis heating belt control technologies primarily rely on single factors such as ambient temperature or compressor status to determine the heating belt's start and stop. This strategy fails to comprehensively consider other important factors such as humidity, easily leading to over-protection or under-protection, increasing energy consumption or reducing reliability. Furthermore, most systems do not adequately consider the risk of condensate freezing when the compressor shuts down, lack intelligent emergency response in case of temperature sensor failure, and have inadequate heating belt operation strategies after defrosting. These problems all affect the effectiveness and energy efficiency of heat pump systems and urgently require improvement. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide an adaptive control method, device and medium for chassis heating belt of a heat pump system.

[0005] The first aspect of this invention provides an adaptive control method for the chassis heating belt of a heat pump system, comprising the following steps:

[0006] Upon receiving the enable signal, the current state of the heat pump system is determined and designated as the first state.

[0007] The chassis heating element is activated based on the first state.

[0008] Once the chassis heating belt is activated, calculate the minimum operating time of the chassis heating belt;

[0009] Once the chassis heating belt reaches the minimum operating time, the current state of the heat pump system is determined as the second state.

[0010] The chassis heating belt is turned off according to the second state control.

[0011] Further, the first state specifically includes a defrosting state, a running state, and a shutdown state; the step of controlling the chassis heating belt to start according to the first state specifically includes the following steps:

[0012] When the first state is defrosting, the chassis heating belt will automatically start;

[0013] When the first state is the running state, the chassis heating belt is activated when the chassis temperature of the heat pump system is not greater than the first temperature or the ambient temperature is not greater than the second temperature.

[0014] When the first state is the shutdown state, the chassis heating belt is activated when the ambient humidity is not less than the first humidity and the chassis temperature of the heat pump system is not greater than the third temperature or the ambient temperature is not greater than the fourth temperature.

[0015] Furthermore, the chassis temperature of the heat pump system is collected by a chassis temperature sensor; the ambient temperature is collected by an ambient temperature sensor; and the ambient humidity is collected by an ambient humidity sensor and / or cloud-based humidity data.

[0016] Furthermore, when neither the chassis temperature nor the ambient temperature of the heat pump system can be obtained, the step of controlling the chassis heating belt to start according to the first state further includes the following steps:

[0017] Obtain the ambient humidity of the heat pump system;

[0018] When the ambient humidity is not less than the first humidity, the chassis heating belt starts running for a first preset time and then starts intermittently every second preset time.

[0019] When the ambient humidity is not less than the second humidity and less than the first humidity, the chassis heating belt starts running for a first preset time and then starts intermittently every third preset time.

[0020] When the ambient humidity is less than the second humidity, the chassis heating belt starts running for a first preset time, and then starts intermittently every fourth preset time.

[0021] The first preset duration is not less than the minimum running time; the second preset duration is less than the third preset duration; and the third preset duration is less than the fourth preset duration.

[0022] Furthermore, the minimum operating time of the chassis heating belt is calculated using the following formula:

[0023] T = max(T) min ,k×T defrost +bc×T env) ;

[0024] In the formula, T min T represents the preset minimum runtime threshold. defrost T represents the interval between the time the heat pump system is in defrost mode and the current time. envdenoted by , where is the ambient temperature, k is the influence coefficient of the defrosting time of the heat pump system, b is the compensation time for the preheating of the chassis heating belt, and c is the correction coefficient for the ambient temperature.

[0025] Furthermore, it also includes the following steps:

[0026] When T defrost Less than the first time threshold and T env When the first temperature threshold is reached, the minimum running time is set to zero;

[0027] When T env When the second temperature threshold is reached, the minimum running time is set to zero;

[0028] When the calculated minimum running time is greater than the second time threshold, the minimum time threshold is set as the second time threshold.

[0029] Furthermore, the second state specifically includes an operating state and a shutdown state; the step of controlling the chassis heating belt to shut down according to the second state specifically includes the following steps:

[0030] When the second state is the running state, the chassis heating belt is turned off when the chassis temperature of the heat pump system is not lower than the fifth temperature or the ambient temperature is not lower than the sixth temperature.

[0031] When the second state is the shutdown state, the chassis heating belt is turned off when the chassis temperature of the heat pump system is not less than the seventh temperature, or when the ambient temperature is not less than the eighth temperature and the chassis temperature of the heat pump system is greater than the third temperature, or when the ambient humidity is greater than the third humidity.

[0032] Furthermore, it also includes the following steps:

[0033] When no enable signal is received, the chassis heating belt is turned off.

[0034] A second aspect of the present invention provides an electronic device, including a processor and a memory;

[0035] The memory is used to store programs;

[0036] The processor executes the program to implement the adaptive control method for the chassis heating belt of a heat pump system as described in the first aspect.

[0037] A third aspect of the present invention provides a computer-readable storage medium storing a program that is executed by a processor to implement the adaptive control method for the chassis heating element of a heat pump system as described in the first aspect.

[0038] This invention also discloses a computer program product or computer program, which includes computer instructions stored in a computer-readable storage medium. A processor of a computer device can read the computer instructions from the computer-readable storage medium and execute the computer instructions, causing the computer device to perform the aforementioned method.

[0039] The embodiments of the present invention have the following beneficial effects: The adaptive control method, device, and medium for the chassis heating belt of a heat pump system provided by the present invention can control the start and stop of the chassis heating belt based on comprehensive factors such as temperature, humidity, and compressor operating status. Combined with dynamic time control logic and fault emergency strategies, it achieves more intelligent and efficient chassis heating belt control. Through precise sensing and adjustment, the present invention can effectively improve the stability of the heat pump system in extreme environments, reduce the risk of equipment icing, and simultaneously reduce energy consumption, meeting the requirements of modern energy conservation, environmental protection, and intelligent development.

[0046] 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.

[0047] Existing chassis heating belt control technology still has the following defects and shortcomings:

[0048] 1. Lack of multi-factor comprehensive judgment logic:

[0049] In existing technologies, the activation of chassis heating belts is often based on a single ambient temperature or compressor operating status, such as activating the heating belt when the ambient temperature is below a certain set value (e.g., -2°C). However, this control strategy based on a single factor cannot fully reflect the actual risk of chassis icing. For example, when the ambient humidity is high, even if the temperature has not reached the freezing point, condensation may still cause the chassis to freeze; while in a dry environment, a slightly lower temperature may not lead to icing. Therefore, traditional control logic is prone to problems of "over-protection" or "missed protection," increasing unnecessary energy consumption or reducing the reliability of protection.

[0050] 2. The compressor's off state was not adequately considered:

[0051] Most existing systems only activate the chassis heating belt when the compressor is running. However, when the compressor is off or the heat pump is in standby mode, condensate may still freeze if the ambient temperature is low and the humidity is high. In this case, the logic of not activating the heating belt may cause chassis protection to fail, especially when the equipment is shut down for a long time, the icing problem will be more serious, affecting the normal start-up and operation of the equipment.

[0052] 3. Inadequate emergency control in case of failure:

[0053] In actual operation, chassis temperature sensors or ambient temperature sensors may malfunction due to harsh conditions or other reasons. When a temperature sensor fails, current technology typically stops the heating element operation directly or operates with a fixed logic, lacking intelligent countermeasures, which may lead to equipment protection failure or significant energy waste. For example, when a temperature sensor fails, in high humidity and low temperature environments, it is impossible to adjust the heating element's operating status based on humidity and other information, further reducing system reliability.

[0054] 4. The operation strategy of the heating belt after defrosting is not perfect:

[0055] After the heat pump completes defrosting, condensate may still remain on the chassis, requiring the heating element to continue running for a period to prevent it from freezing. However, current technologies lack the logic to dynamically adjust the heating element's operating time based on actual defrosting time and environmental conditions, mostly employing fixed-duration operation, which may lead to energy waste or insufficient protection.

[0056] To address the aforementioned problems, the first embodiment of the present invention provides an adaptive control method for the chassis heating element of a heat pump system, such as... Figure 1 As shown, it includes the following steps:

[0057] S1. Upon receiving the enable signal, determine the current state of the heat pump system as the first state;

[0058] S2. The chassis heating belt is activated according to the first state control;

[0059] S3. Calculate the minimum operating time of the chassis heating belt after it is activated;

[0060] S4. Once the chassis heating belt reaches its minimum operating time, determine the current state of the heat pump system as the second state;

[0061] S5. Control the chassis heating belt to turn off according to the second state.

[0062] The adaptive control method for chassis heating belt of heat pump system provided in this embodiment of the invention can control chassis heating belt based on comprehensive factors such as temperature, humidity, and heat pump system operating status. Combined with dynamic time control logic and fault emergency strategy, it achieves more intelligent and efficient chassis heating belt control.

[0063] The implementation process of each step of this invention is described in detail below:

[0064] S1. Upon receiving the enable signal, determine the current state of the heat pump system as the first state.

[0065] In this embodiment of the invention, the enable signal H01 is used to control the start of the chassis heating belt. When the enable signal H01 is at a high level, the chassis heating belt performs subsequent start and stop judgments based on temperature, humidity and system status.

[0066] Preferably, the method further includes the following steps:

[0067] S1-1. When no enable signal is received, control the chassis heating belt to turn off.

[0068] When the enable signal H01 is low, the chassis heating belt is automatically turned off. Therefore, the heat pump system operator can force the chassis heating belt to shut off using the enable signal.

[0069] S2. The chassis heating belt is activated according to the first state.

[0070] The obtained operating state (first state) of the heat pump system may include defrosting state, running state, and shutdown state. In this embodiment of the invention, the start and stop of the chassis heating belt are controlled according to the system state. When the heat pump system is in different operating states, different steps and procedures are applied for control.

[0071] Defrosting mode: When the heat pump system is in defrosting mode, it uses high-temperature, high-pressure refrigerant to melt the frost layer on the evaporator, forming condensate. Therefore, to prevent the condensate from refreezing on the chassis, the chassis heating belt needs to be kept on throughout the defrosting process until the heat pump system exits defrosting mode.

[0072] Operating Status: When the heat pump system is in operation, localized low-temperature zones may appear near some components (such as the evaporator), causing a large amount of condensate to form. Therefore, this embodiment of the invention acquires the chassis temperature and ambient temperature of the heat pump system when it is in operation. When the chassis temperature is not greater than a first temperature T01, or the ambient temperature is not greater than a second temperature T02, the chassis heating element is activated. Preferably, in this embodiment, the first temperature T01 is set to be greater than the second temperature T02, for example, T01 = 2℃ and T02 = -2℃. This is because the chassis temperature can more sensitively reflect the actual risk of icing, while the ambient temperature has a smaller direct impact on the risk of icing. Since the chassis temperature is closer to the condensate, its rise and fall are more affected by the condensate and the heat from the equipment; therefore, the threshold for the chassis temperature is relatively higher.

[0073] Shutdown State: When the heat pump system is in a shutdown state, although there will be no localized low-temperature zones due to the cessation of operation of all components, the chassis of the heat pump system may still freeze due to the low-temperature and high-humidity environment. Therefore, this embodiment of the invention acquires the chassis temperature, ambient temperature, and ambient humidity of the heat pump system when it is in a shutdown state. When the ambient humidity is not less than the first humidity T09, and the chassis temperature is not greater than the third temperature T03 or the ambient temperature is not greater than the fourth temperature T04, the chassis heating belt is activated. Specifically, an ambient humidity not less than the first humidity T09 indicates that the environment in which the heat pump system is located is a high-humidity environment, thus requiring prevention of freezing due to low temperatures. Since the heat pump system does not actively generate low-temperature zones in the shutdown state, the third temperature T03 is slightly higher than the first temperature T01 set in the operating state, while the fourth temperature T04 is not much different from the second temperature T02, achieving a similar chassis anti-freezing effect based on ambient temperature.

[0074] In this embodiment of the invention, the chassis temperature of the heat pump system is collected by a chassis temperature sensor; the ambient temperature is collected by an ambient temperature sensor; and the ambient humidity is collected by an ambient humidity sensor and / or cloud-based humidity data.

[0075] In some embodiments, the sensors installed on the heat pump system may malfunction, causing the chassis heating element to become uncontrollable and resulting in chassis freezing. In this embodiment of the invention, the ambient humidity can be obtained via the cloud, thus enabling independent control of the chassis heating element based on ambient humidity, achieving fault protection for the heat pump system.

[0076] Specifically, the chassis heating belt control based on ambient humidity is intermittent, determined by the ambient humidity obtained by the heat pump system. When the ambient humidity is not less than the first humidity T09, the chassis heating belt starts operating for a first preset duration T13, and then intermittently starts every second preset duration T14. When the ambient humidity is not less than the second humidity T10 and less than the first humidity T9, the chassis heating belt starts operating for a first preset duration T13, and then intermittently starts every third preset duration T15. When the ambient humidity is less than the second humidity T10, the chassis heating belt starts operating for a first preset duration T13, and then intermittently starts every fourth preset duration T16. In this embodiment of the invention, the first preset duration T13 is set to be not less than the minimum operating time T12; the second preset duration T14 is less than the third preset duration T15; and the third preset duration T15 is less than the fourth preset duration T16. This ensures that the higher the ambient humidity, the higher the operating frequency of the heat pump system, achieving a better balance between energy saving and efficiency.

[0077] When the heat pump system intermittently controls the start and stop of the chassis heating belt, it will also alarm the operator to inform the user of the sensor malfunction and remind the operator to repair it as soon as possible.

[0078] S3. Calculate the minimum running time of the chassis heating belt after it is activated.

[0079] In this embodiment of the invention, the minimum operating time T12 of the chassis heating belt is calculated using the following formula:

[0080] T = max(T) min ,k×T defrost +bc×T env) ;

[0081] In the formula, T min T represents the preset minimum runtime threshold. defrost T represents the interval between the time the heat pump system is in defrost mode and the current time. env denoted by , where is the ambient temperature, k is the influence coefficient of the defrosting time of the heat pump system, b is the compensation time for the preheating of the chassis heating belt, and c is the correction coefficient for the ambient temperature.

[0082] In this embodiment of the invention, the minimum operating time of the chassis heating belt is calculated in the data processing module of the heat pump system. When the heat pump system exits defrost mode, the data processing module automatically calculates the minimum operating time. The formula parameter T... mink, b, and c are preset values. Specific values ​​can be manually optimized based on the actual operating data of the heat pump system to ensure precise and efficient formula control. In this embodiment, Tmin is set to 5 minutes, indicating that the basic operating time of the chassis heating element is no less than 5 minutes, ensuring sufficient time for the system to heat the chassis and prevent freezing even at high ambient temperatures. k = 4, indicating that each minute of defrosting time corresponds to 4 minutes of heating operation. This is because the moisture generated during 1 minute of defrosting requires approximately 4 minutes of extended heating to remove it. The k value can be adjusted based on the power of the electric heating element and the equipment's drainage structure design. b = 10, indicating that the chassis heating element requires 10 minutes of preheating time. The b value can be set based on experimental data and the expected worst-case environmental conditions. c = 0.5, indicating that for every 1°C increase in ambient temperature, the operating time is reduced by 0.5 minutes. When setting the c value, a larger value should be selected if the heating element is sensitive to temperature changes, has high power, and good thermal conductivity; a smaller value should be selected if the heating element heats up slowly or is a low-power device.

[0083] For the limiting case in the formula, the embodiments of the present invention have the following design:

[0084] When T defrost Less than the first time threshold and T env When the first temperature threshold is reached, the minimum running time is set to zero. Within a certain period after the defrost mode ends (set to 2 minutes in this embodiment), if the ambient temperature is higher than a certain temperature threshold (set to -10℃ in this embodiment), the heat pump system chassis is unlikely to experience icing. Therefore, the minimum running time T12 within this time range is designed to be zero.

[0085] When T env When the second temperature threshold is reached, the minimum operating time is set to zero. If the ambient temperature itself is higher than a certain temperature threshold (set to 6°C in this embodiment), the heat pump system chassis is unlikely to freeze, so the minimum operating time T12 within this time range is designed to be zero.

[0086] When the calculated minimum running time is greater than the second time threshold, the minimum time threshold is set to the second time threshold. If the calculated minimum running time is greater than the second time threshold (30 minutes in this embodiment), the chassis heating belt will only be controlled to operate at the second time threshold as the upper limit to prevent energy waste.

[0087] S4. Once the chassis heating belt reaches its minimum operating time, determine the current state of the heat pump system as the second state.

[0088] In this embodiment of the invention, when the chassis heating belt reaches the minimum operating time, the heat pump system will reconfirm the current working status to control whether the chassis heating belt is turned off or continues to operate.

[0089] S5. Control the chassis heating belt to turn off according to the second state.

[0090] In this embodiment of the invention, when the heat pump system is in defrost mode, the chassis heating belt will automatically shut off when exiting defrost mode. For the operating and shutdown modes, control is achieved through the following steps:

[0091] Operating status: When the heat pump system is in operation, the heat pump system will control the chassis heating belt to shut down based on the chassis temperature or ambient temperature. It will shut down when the chassis temperature of the heat pump system is not lower than the fifth temperature T05 or the ambient temperature is not lower than the sixth temperature T06.

[0092] Shutdown status: When the heat pump system is in shutdown status, the heat pump system will control the chassis heating belt to shut down based on chassis temperature, ambient temperature, or ambient humidity; it will shut down when the chassis temperature of the heat pump system is not lower than the seventh temperature T07, or when the ambient temperature is not lower than the eighth temperature T08 and the chassis temperature of the heat pump system is greater than the third temperature T03, or when the ambient humidity is greater than the third humidity T11.

[0093] A schematic diagram of the entire invention in real time is shown below. Figure 2 As shown in the table below, the parameter definitions involved in the embodiments of the present invention are summarized as follows:

[0094]

[0095]

[0096] The embodiments of the present invention have at least the following technical advantages:

[0097] 1. Intelligent control: The running time is dynamically adjusted through formula algorithms to adapt to various complex scenarios.

[0098] 2. Energy saving optimization: Reduce unnecessary operating time and reduce energy consumption while meeting antifreeze requirements.

[0099] 3. Safe and reliable: In the event of sensor failure, it automatically enters protection mode to ensure normal system operation.

[0100] 4. Flexible expansion: The coefficients in the formula can be adjusted according to the actual application scenario to adapt to different working conditions.

[0101] The method described in this invention can dynamically adjust the start and stop of the heating belt based on real-time environmental conditions and humidity changes under various states, including defrosting, compressor operation, compressor shutdown, and temperature sensor failure, to maximize energy efficiency and ensure safe operation of the equipment under low temperature and high humidity conditions. This invention combines dynamic time control logic and fault emergency strategies to achieve more intelligent and efficient chassis heating belt control. Through precise sensing and adjustment, this invention can effectively improve the stability of the heat pump system in extreme environments, reduce the risk of equipment icing, and simultaneously reduce energy consumption, meeting the requirements of modern energy conservation, environmental protection, and intelligent development.

[0102] By implementing this invention, the antifreeze performance of heat pump systems in low-temperature environments can be significantly improved, while reducing energy waste during heating element operation and extending equipment lifespan. It is particularly suitable for low-temperature, high-humidity working environments and can intelligently adjust operating strategies when equipment malfunctions, ensuring safe and efficient operation. This provides a new solution for antifreeze protection of heat pump systems. Compared to traditional fixed-segment logic control, this invention can more accurately adapt to complex and changing environmental conditions and has broad market application value.
