Description

Technical Field

[0001] The invention relates to the technical field of heat pump system control, and in particular to a chassis heating belt adaptive control method, device and medium of a heat pump system. Background Art

[0002] With the widespread application of heat pump systems, their reliable operation in extreme environments such as low temperature and high humidity has attracted more and more attention. In cold environments, condensed water often accumulates on the chassis of heat pumps. When the ambient temperature drops below freezing, this condensed water may freeze quickly, causing the chassis to be covered with ice. The ice layer not only affects the smooth drainage of the heat pump, but may also increase the load on the compressor and other key components. In severe cases, it will cause equipment damage and shorten the service life of the system. Therefore, in the design of heat pump systems, the chassis is usually de-iced and protected by chassis heating belts.

[0003] However, existing chassis heating belt control technology mainly relies on a single factor such as ambient temperature or compressor status to determine the start and stop of the heating belt. This strategy fails to comprehensively consider other important factors such as humidity, which can easily lead to over-protection or under-protection, increase energy consumption or reduce reliability. In addition, most systems do not fully consider the risk of condensate freezing when the compressor is shut down, lack intelligent emergency response when the temperature sensor fails, and the operation strategy of the heating belt after defrosting is imperfect. These problems have affected the effectiveness and energy efficiency of the heat pump system and are in urgent need of improvement. Summary of the invention

[0004] In view of this, an embodiment of the present invention provides a chassis heating zone adaptive control method, device and medium of a heat pump system.

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

[0006] After receiving the enable signal, determining the current state of the heat pump system as a first state;

[0007] Controlling the chassis heating belt to start according to the first state;

[0008] When the chassis heating belt is started, calculate the minimum running time of the chassis heating belt;

[0009] When the operating time of the chassis heating belt reaches the minimum operating time, determining the current state of the heat pump system as the second state;

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

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

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

[0013] When the first state is the running state, the chassis heating belt is started 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;

[0016] Furthermore, when the chassis temperature and the ambient temperature of the heat pump system cannot be obtained, the control of starting the chassis heating belt according to the first state further includes the following steps:

[0017] Get 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 to run 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 to run for a first preset time and then starts intermittently every third preset time;

[0020] When the ambient humidity is lower than the second humidity, the chassis heating belt starts to run for the first preset time and then starts intermittently every fourth preset time;

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

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

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

[0024] Where, T min Indicates the preset minimum running time threshold, T defrost Indicates the interval between the time when the heat pump system is in defrosting state and the current time, T envrepresents the ambient temperature, k represents the influence coefficient of the defrost time of the heat pump system, b represents the compensation time of the chassis heating belt preheating, and c represents the correction coefficient of the ambient temperature.

[0025] Furthermore, the method further comprises the following steps:

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

[0027] When T env When a second temperature threshold is reached, setting the minimum operating time 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 a running state and a shutdown state; and controlling the chassis heating belt to turn off according to the second state specifically includes the following steps:

[0030] When the second state is the operating state, the chassis heating belt is turned off when the chassis temperature of the heat pump system is not less than the fifth temperature or the ambient temperature is not less 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, the method further comprises the following steps:

[0033] When the enable signal is not received, the chassis heating belt is controlled to be 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 chassis heating belt adaptive control method of the heat pump system described in the first aspect.

[0037] A third aspect of the present invention provides a computer-readable storage medium, wherein the storage medium stores a program, and the program is executed by a processor to implement the chassis heating belt adaptive control method of a heat pump system according to the first aspect.

[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The existing chassis heating belt control technology still has the following defects and deficiencies:

[0048] 1. Lack of comprehensive judgment logic of multiple factors:

[0049] In the prior art, the chassis heating belt is mostly turned on based on a single ambient temperature or compressor operating status. For example, the heating belt is turned on when the ambient temperature is lower than a certain set value (such as -2°C). However, this control strategy based on a single factor cannot fully reflect the real risk of chassis icing. For example, when the ambient humidity is high, even if the temperature does not reach the freezing point, the chassis may freeze due to condensation; in a dry environment, a slightly lower temperature may not cause icing. Therefore, traditional control logic is prone to problems of "over-protection" or "missing protection", increasing unnecessary energy consumption or reducing the reliability of protection.

[0050] 2. Not fully considering the compressor shutdown state:

[0051] Most existing systems only turn on the chassis heating belt when the compressor is running, but when the compressor is turned off or the heat pump is in standby mode, if the ambient temperature is low and the humidity is high, the condensed water may still freeze. At this time, the logic of not enabling the heating belt may cause the 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 startup and operation of the equipment.

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

[0053] In actual operation, the chassis temperature sensor or the ambient temperature sensor may fail due to adverse conditions or other reasons. When the temperature sensor fails, the existing technology usually directly stops the operation of the heating belt or operates it with fixed logic, lacking intelligent response measures, which may cause equipment protection failure or serious energy waste. For example, when the temperature sensor fails, in a high humidity and low temperature environment, the working state of the heating belt cannot be adjusted according to other information such as humidity, further reducing the reliability of the system.

[0054] 4. Imperfect operation strategy of heating belt after defrosting:

[0055] After the heat pump has finished defrosting, since condensed water may still remain on the chassis, it is usually necessary to continue running the heating belt for a period of time to prevent the condensed water from freezing. However, the existing technology lacks the logic to dynamically adjust the running time of the heating belt according to the actual defrosting time and environmental conditions. Most of them use fixed-duration operation, which may lead to energy waste or insufficient protection.

[0056] To solve the above problems, the first embodiment of the present invention provides a chassis heating zone adaptive control method of a heat pump system, such as Figure 1 As shown, the following steps are included:

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

[0058] S2. Control the chassis heating belt to start according to the first state;

[0059] S3. After the chassis heating belt is started, the minimum operation time of the chassis heating belt is calculated;

[0060] S4. When the running time of the chassis heating belt reaches the minimum running time, the current state of the heat pump system is determined as the second state;

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

[0062] The chassis heating belt adaptive control method of the heat pump system provided in the embodiment of the present invention can control the chassis heating belt based on comprehensive factors such as temperature, humidity, and the operating status of the heat pump system, and combines dynamic time control logic and fault emergency strategy to achieve smarter and more efficient chassis heating belt control.

[0063] The following specifically describes the implementation process of each step of the present invention:

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

[0065] In the embodiment of the present 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 comprises the following steps:

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

[0068] When the enable signal H01 is at a low level, the chassis heating belt is automatically turned off. Therefore, the heat pump system operator can forcibly turn off the chassis heating belt through the enable signal.

[0069] S2. Control the chassis heating belt to start according to the first state.

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

[0071] Defrosting state: When the heat pump system is in the defrosting state, the heat pump system will use high-temperature and high-pressure refrigerant to melt the frost layer on the evaporator to form condensed water. Therefore, in order to prevent the condensed water from freezing again on the chassis, it is necessary to control the chassis heating belt to be turned on throughout the defrosting process of the heat pump system until the heat pump system exits the defrosting state.

[0072] Running state: When the heat pump system is in the running state, local low-temperature areas may appear near some components (such as the evaporator) in the heat pump system, causing a large amount of condensed water to condense. Therefore, the embodiment of the present invention obtains the chassis temperature and ambient temperature of the heat pump system when the heat pump system is in the running state, and when the chassis temperature is not greater than the first temperature T01, or the ambient temperature is not greater than the second temperature T02, the chassis heating belt is controlled to start. Preferably, in the embodiment of the present invention, the first temperature T01 is set to be greater than the second temperature T02, for example, T01=2°C, T02=-2°C. This is because the chassis temperature can more sensitively reflect the actual risk of freezing, while the direct impact of the ambient temperature on the risk of freezing is smaller. Based on the fact that the chassis temperature is closer to the location of the condensed water, its rise and fall are more affected by the condensed water and the heat of the equipment, so the threshold of the chassis temperature is relatively higher.

[0073] Shutdown state: When the heat pump system is in the shutdown state, since the various components of the heat pump system stop running, although there will be no local low temperature area, the chassis of the heat pump system may still freeze due to the low temperature and high humidity environment. Therefore, the embodiment of the present invention obtains the chassis temperature, ambient temperature and ambient humidity of the heat pump system when the heat pump system is in the 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 controlled to start. Specifically, the ambient humidity is not less than the first humidity T09, which means that the environment in which the heat pump system is located is a high humidity environment, so it is necessary to prevent freezing caused by low temperature. Since the heat pump system will not actively generate a low temperature area in the shutdown state, the third temperature T03 is slightly higher than the first temperature T01 set in the running state, and 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 the embodiment of the present 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 humidity data.

[0075] In some embodiments, the sensor installed on the heat pump system may fail, causing the chassis heating belt to be unable to be controlled and the chassis to freeze. In the embodiment of the present invention, the ambient humidity can be obtained through the cloud, so that the chassis heating belt can be controlled based on the ambient humidity alone, and the fault protection of the heat pump system can be realized.

[0076] Specifically, the chassis heating belt control based on ambient humidity is intermittent control, which is determined according to 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 to run for the first preset time T13, and then starts intermittently every second preset time 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 to run for the first preset time T13, and then starts intermittently every third preset time T15; when the ambient humidity is less than the second humidity T10, the chassis heating belt starts to run for the first preset time T13, and then starts intermittently every fourth preset time T16. In the embodiment of the present invention, the first preset time T13 is set to be not less than the minimum operating time T12; the second preset time T14 is less than the third preset time T15; the third preset time T15 is less than the fourth preset time T16, so that when the ambient humidity is higher, the operating frequency of the heat pump system is also higher, and a better balance is achieved between energy saving and efficiency.

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

[0078] S3. After the chassis heating belt is started, the minimum operating time of the chassis heating belt is calculated.

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

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

[0081] Where, T min Indicates the preset minimum running time threshold, T defrost Indicates the interval between the time when the heat pump system is in defrosting state and the current time, T env represents the ambient temperature, k represents the influence coefficient of the defrost time of the heat pump system, b represents the compensation time of the chassis heating belt preheating, and c represents the correction coefficient of the ambient temperature.

[0082] In the embodiment of the present 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 the defrosting mode, the data processing module will automatically calculate the minimum operating time. min, k, b, and c are preset values. The specific values ​​can be manually optimized according to the actual operating data of the heat pump system to ensure that the formula control is accurate and efficient. In the embodiment of the present invention, Tmin=5 minutes is set, indicating that the basic operating time of the chassis heating belt is not less than 5 minutes, ensuring that when the ambient temperature is high, the system has enough time to heat the chassis to prevent freezing. k=4, indicating that each minute of defrosting time corresponds to 4 minutes of heating operation. This is because the water generated by 1 minute of defrosting requires about 4 minutes of heating and discharge. The k value can be adjusted in combination with the power of electric heating and the design of the drainage structure of the equipment. b=10, indicating that the chassis heating belt preheating requires 10 minutes of running time, and the b value can be set according to experimental data and the expected worst environmental conditions. c=0.5, indicating that the running time is reduced by 0.5min for every 1°C increase in ambient temperature. In the setting of the c value, if the heating belt is sensitive to temperature changes, high power, and good thermal conductivity, a larger value is selected; if the heating belt heats up slowly or is a low-power device, a smaller value is selected.

[0083] For the extreme case in the formula, the embodiment of the present invention has 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 operating time is set to zero. Within a period of time (set to 2 minutes in the embodiment of the present invention) after the defrost mode ends, if the ambient temperature is higher than a certain temperature threshold (set to -10°C in the embodiment of the present invention), the chassis of the heat pump system is unlikely to freeze, so the minimum operating 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 the embodiment of the present invention), the chassis of the heat pump system is unlikely to freeze, so the minimum operating time T12 within this time range is designed to be zero.

[0086] When the calculated minimum operating time is greater than the second time threshold, the minimum time threshold is set to the second time threshold. If the calculated minimum operating time is greater than the second time threshold as the upper limit (30 minutes in the embodiment of the present invention), the embodiment of the present invention will only control the chassis heating belt to operate with the second time threshold as the upper limit to prevent energy waste.

[0087] S4. When the operating time of the chassis heating belt reaches the minimum operating time, the current state of the heat pump system is determined as the second state.

[0088] In the embodiment of the present invention, when the operating time of the chassis heating belt reaches the minimum operating time, the heat pump system will reconfirm the current working status to control the chassis heating belt to shut down or continue to run.

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

[0090] In the embodiment of the present invention, when the heat pump system is in the defrosting state, the chassis heating belt will automatically turn off when exiting the defrosting state, and for the running state and the shutdown state, control is performed through the following steps:

[0091] Running state: When the heat pump system is in the running state, the heat pump system will control the chassis heating belt to be turned off based on the chassis temperature or the ambient temperature, and will be turned off when the chassis temperature of the heat pump system is not less than the fifth temperature T05 or the ambient temperature is not less than the sixth temperature T06.

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

[0093] The overall real-time schematic diagram of the present invention is as follows Figure 2 The parameter definitions involved in the embodiments of the present invention are summarized as shown in the following table:

[0094]

[0095]

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

[0097] 1. Intelligent control: Dynamically adjust the running time through formula algorithms to adapt to a variety of complex scenarios.

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

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

[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 of the embodiment of the present invention can dynamically adjust the start and stop of the heating belt according to real-time environmental conditions and humidity changes under various conditions such as defrosting, compressor operation, compressor shutdown, and temperature sensor failure, so as to maximize energy efficiency and ensure the safe operation of the equipment under low temperature and high humidity conditions. The present invention combines dynamic time control logic and fault emergency strategy to achieve smarter and more efficient chassis heating belt control. Through precise perception 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 reduce energy consumption, meeting the requirements of modern energy conservation, environmental protection and intelligent development.

[0102] Through the implementation of the present invention, the antifreeze performance of the heat pump system in a low-temperature environment can be significantly improved, while reducing the energy consumption waste during the operation of the heating belt, extending the service life of the equipment, and being particularly suitable for low-temperature and high-humidity working environments. It can also intelligently adjust the operation strategy when the equipment fails to ensure that the equipment works safely and efficiently. It provides a new solution for the antifreeze protection of the heat pump system. Compared with the traditional fixed segmented logic control, the present invention can more accurately adapt to complex and changeable environmental conditions and has a wide range of market application value.
