[0002] Unlike traditional fuel vehicles that use waste heat from the engine to heat the passenger compartment, new energy vehicles need to consume electricity to heat the passenger compartment. If the same amount of heating is required, the heat pump heating mode of the heat pump system is more efficient and consumes less energy than the heating methods of air PTC (Positive Temperature Coefficient) heaters or water PTC heaters. Therefore, in recent years, heat pump systems have been widely used in pure electric vehicles. For example, when the passenger compartment needs to be heated, the efficient and energy-saving heat pump heating mode is preferred.

[0054] 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.

[0055] In the description of the embodiments of the present application, the technical terms "first", "second", "third", etc. are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0056] Compared with traditional fuel vehicles, electric vehicles need to consume electricity to heat the passenger compartment, which is different from traditional fuel vehicles that use waste heat generated by the engine to heat the passenger compartment. Heat pump systems have been widely used in pure electric vehicles. When there is a heating demand in the passenger compartment, the efficient and energy-saving heat pump heating mode will be given priority as much as possible. When there is a heating demand in the passenger compartment, in theory, the heat pump heating-related mode should be selected, and when there is a cooling and heating demand in the passenger compartment at the same time, the heat pump dehumidification mode is relatively energy-efficient. However, the traditional method does not consider the safety and stability of the operation of the heat pump system when there is a heating demand or a cooling and heating demand at the same time. Therefore, optimizing the operation of the heat pump system and improving the stability of the heat pump system are technical issues that need to be solved urgently.

[0057] In order to solve this technical problem, a heat pump mode control method is proposed. When there is a temperature control demand, the temperature control demand parameter associated with the heat pump system is obtained, and it is judged whether the temperature control demand parameter meets the preset judgment condition. If it meets the condition, the target heat pump mode corresponding to the temperature control instruction is disabled. Otherwise, the heat pump system is controlled to operate in the target heat pump mode corresponding to the temperature control instruction. Under the premise of ensuring system safety and stable temperature control, the energy-efficient target heat pump mode is used as much as possible.

[0058] The heat pump mode control method disclosed in the embodiment of the present application can be used in vehicles, ships or aircraft, etc., but is not limited to the use. The heat pump mode control method provided in the embodiment of the present application can be applied to Figure 1 In the application system shown, Figure 1The application system shown includes a schematic diagram of the structure of a vehicle-mounted heat pump system and a coolant circulation system. The heat pump system includes a compressor 101, an air conditioner 102, an external condenser 103, a blower 104, an evaporator 105, an internal condenser 106, an electronic expansion valve 304, a solenoid valve 305, and a one-way stop valve 301. The coolant circulation system includes a warm air circuit pump 201, a water heating PTC 202, a warm air core 203, a chiller 204, a battery module 205, a motor module 206, a battery circuit pump 207, a motor circuit pump 208, a radiator 209, a three-way water valve 302, and a four-way water valve 303. In the coolant circulation system, the motor module 206, the four-way water valve 303, the radiator 209, and the motor circuit pump 208 form a motor circuit.

[0059] The refrigeration circuit includes two types of circuits: compressor-internal condenser-external condenser-compressor, and compressor-internal condenser-(external condenser and evaporator in parallel)-compressor. Figure 1 Some electronic expansion valves, solenoid valves and one-way stop valves are identified in the figure. The control methods and functions of the electronic expansion valves, solenoid valves and one-way stop valves can be realized by existing methods. Figure 1 The marked solenoid valve 305 and the one-way stop valve 301 indicate that the solenoid valve 305 can be used to control the air temperature at the outlet side of the evaporator 105 so that the temperature reaches the target air temperature. A one-way stop valve 301 is installed at the output end of the internal condenser 106 to prevent the refrigerant from flowing back.

[0060] The blower 104 draws in the air in the vehicle and blows it toward the evaporator 105. The water vapor in the air condenses and precipitates when it is cooled, thereby achieving the purpose of dehumidification. The external condenser 103 can absorb heat from the environment outside the vehicle by evaporating the refrigerant, and then the internal condenser 106 supplements the heat to the cooled air in the air conditioning box 102 to raise the temperature. In this cycle, the purpose of dehumidification in the vehicle is achieved.

[0061] After the compressor 101 compresses the gaseous refrigerant, it is input into the internal condenser 106 to release heat and condense; at this time, the blower 104 blows the air in the passenger compartment to the internal condenser 106 to heat it, and then blows it back to the passenger compartment from the air outlet to achieve heating of the passenger compartment. The condensed refrigerant enters the evaporator 105 to absorb heat and evaporate, and finally the refrigerant returns to the compressor 101.

[0062] The coolant circulation system includes a warm air circuit and a battery circuit, wherein the warm air circuit starts from the warm air circuit pump 201, passes through the water heating PTC 202, the warm air core 203, and then returns to the warm air circuit pump 201 through the three-way water valve 302. The battery circuit passes through the three-way water valve 302, passes through the battery circuit pump 207 and the battery module 205, and returns to the warm air circuit pump 201. After receiving the connection command, the four-way water valve 303 connects the battery circuit with the motor circuit.

[0063] It should be noted that the above Figure 1 The application system shown is only an example, and the heat pump mode control method of the present application can also be applied to various systems that can implement the heat pump mode control method.

[0064] In an exemplary embodiment, Figure 2 As shown, a heat pump mode control method is provided, which is applied to Figure 1 The application environment is taken as an example to illustrate, including the following steps 202 to 204.

[0065] in:

[0066] Step 202, receiving a temperature control instruction for the passenger compartment, and obtaining a temperature control demand parameter associated with the heat pump system.

[0067] The generation of the temperature control command may be triggered by the passenger compartment or initiated by the cloud. The generation of the temperature control command may be triggered by the passenger compartment, including but not limited to triggering the temperature control button on the control panel, triggering the temperature control control, and the vehicle controller automatically generating any one of the temperature control commands when detecting that the temperature of the passenger compartment is not within the preset temperature range. The generation of the temperature control command may be initiated by the cloud, but not limited to obtaining the temperature control command from the cloud. The temperature control command includes the temperature control command for heating and the temperature control command for simultaneous cooling and heating. Simultaneous heating and cooling can be understood as the air conditioning system in the vehicle providing cooling and heating effects at the same time to control the air temperature in the vehicle according to the needs of passengers and drivers.

[0068] The temperature control requirement parameters include, but are not limited to, one or more of the ambient temperature, the air volume of the heater core, the target air outlet temperature, the evaporator air outlet temperature, the heating requirement of the passenger compartment, the number of compressor starts and stops within a preset cycle, the internal circulation ratio, and the fogging risk level. The temperature control requirement parameters can be acquired and collected by sensors that match the temperature control requirement parameter type, such as temperature sensors and humidity sensors. Here, there is no limitation on the method of acquiring the temperature control requirement parameters.

[0069] Exemplarily, a request signal for passenger compartment temperature control is input, that is, a temperature control instruction for the passenger compartment is received, and a temperature control demand parameter for determining the operating condition of the heat pump system is obtained.

[0070] Step 204 : When the temperature control demand parameter satisfies a preset determination condition, the heat pump system is controlled to disable the target heat pump mode corresponding to the temperature control instruction.

[0071] Among them, different temperature control instructions correspond to different target heat pump modes. The target heat pump mode corresponding to the temperature control instruction that requires heating is the heat pump heating mode, and the target heat pump mode corresponding to the temperature control instruction for both cooling and heating is the heat pump dehumidification mode. The dehumidification principle of the heat pump dehumidification mode is that water vapor condenses into water droplets when it is cooled.

[0072] It is understandable that the operation of the heat pump system may involve risks such as noise, risk of fogging in the passenger compartment, unstable temperature control and system instability. Therefore, when a temperature control command for the passenger compartment is received, all temperature control demand parameters associated with the heat pump system are obtained to determine whether all temperature control demand parameters meet the preset judgment mode. If any of the preset judgment conditions is met, the heat pump system is controlled to disable the target heat pump mode corresponding to the temperature control command.

[0073] The preset judgment conditions include the judgment conditions for the compressor to operate beyond the boundary, the judgment conditions for the heating demand being less than the preset value resulting in the frequent start and stop of the compressor, the judgment conditions for the frequent start and stop of the compressor, the judgment conditions for preventing fogging in the passenger compartment, and the judgment conditions for exceeding the normal operation boundary of the heat pump system. It should be noted that disabling can be understood as directly disabling the corresponding target heat pump mode, and does not involve mode switching; switching involves a transition in the process, exiting the current mode and then enabling the target mode, that is, there is a difference between disabling and switching. Although, switching to the target mode usually means disabling the current mode and enabling a new mode. However, whether it involves disabling the current mode depends on the specific design and control logic of the system. Some systems may allow multiple modes to run simultaneously.

[0074] Furthermore, during the switching process, the transition between modes will be unstable and cause system instability. In addition, the control logic involved in the switching process may include detecting conditions, executing switching commands, monitoring the status of the new mode, etc., which may cause system instability during the switching process. This approach is inconsistent with the requirements of this solution, which is to use efficient and energy-saving heat pump related modes as much as possible under the premise of ensuring system safety, no system noise, no risk of fogging in the passenger compartment, and stable temperature control. In other words, "switching to the target mode" and "prohibiting the use of heat pump related modes" look similar on the surface, but they represent different response strategies to the same situation, but the selection of these strategies depends on the specific design and operation logic of the system, and the design of different logical strategies also requires creative labor.

[0075] In the above heat pump mode control method, when the heat pump mode of the passenger compartment is controlled, when the temperature control instruction of the passenger compartment is received, the temperature control demand parameter of the heat pump system is obtained; according to the obtained temperature control demand parameter, it is judged whether the target heat pump mode corresponding to the temperature control instruction can be executed at present, and when the temperature control demand parameter meets the preset judgment condition, the heat pump system is controlled to disable the target heat pump mode corresponding to the temperature control instruction. That is, when there is a temperature control demand, it is pre-judged according to the temperature control demand parameter whether the heat pump system can execute the target heat pump mode, determine the working conditions under which the heat pump system can operate normally, optimize the operation of the heat pump system, and improve the stability of the heat pump system.

[0076] It is understandable that when the passenger cabin needs to be cooled and heated at the same time, selecting the heat pump dehumidification mode may result in insufficient cooling and dehumidification, fogging of the passenger cabin, and damage to the compressor due to frequent start and stop of the compressor. When the passenger cabin needs to be heated, selecting the heat pump heating mode may result in damage to components, noise, and unstable control. Therefore, in an exemplary embodiment, if Figure 3 As shown, step 204 includes steps 302 to 304. Among them:

[0077] Step 302, determining the type of the temperature control instruction.

[0078] The temperature control instruction may be transmitted as a switch signal or an analog signal. For example, 1 represents that the temperature control instruction is the first temperature control instruction requiring both cooling and heating, and 0 represents that the temperature control instruction is the second temperature control instruction requiring heating.

[0079] Step 304 , when the temperature control instruction is a first temperature control instruction requiring simultaneous cooling and heating, and when the temperature control demand parameter meets a preset determination condition, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0080] Step 306 , when the temperature control instruction is the second temperature control instruction requiring heating, and when the temperature control demand parameter meets a preset determination condition, the heat pump system is controlled to disable the heat pump heating mode.

[0081] In the above embodiment, for different types of temperature control instructions, when the temperature control demand parameters meet the preset judgment conditions, the heat pump system is controlled to disable the target heat pump mode corresponding to each temperature control instruction, that is, under different temperature control requirements, the heat pump system is controlled in a targeted manner. Under the premise of ensuring the safety and thermal stability of the heat pump system, the energy-efficient target heat pump mode is used as much as possible, thereby improving energy utilization.

[0082] When determining whether to disable the target heat pump mode corresponding to each temperature control instruction according to different types of temperature control instructions, the preset determination conditions corresponding to different types of temperature control instructions are different. Figure 4 As shown, a heat pump mode control method is provided, including steps 402 to 404, wherein:

[0083] Step 402: When the temperature control instruction is a first temperature control instruction requiring simultaneous cooling and heating, a matching first target determination condition is determined from preset determination conditions according to the first temperature control instruction.

[0084] Step 404: When the temperature control demand parameter meets the first target determination condition, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0085] Among them, the first target judgment condition includes but is not limited to at least one of the judgment condition of compressor over-boundary operation, the judgment condition that the heating demand is less than the preset value resulting in frequent compressor start-stop, the judgment condition of frequent compressor start-stop, the judgment condition of preventing passenger compartment fogging, and the judgment condition of the normal operation boundary of the super heat pump system. The temperature control demand parameters include at least one of the ambient temperature, the air volume of the heater core, the target air outlet temperature, the evaporator air outlet temperature, the heating demand of the passenger compartment, the number of compressor starts and stops within a preset cycle, the internal circulation ratio, and the fogging risk level. The fogging risk level can be determined by comparing the temperature difference between the in-vehicle temperature and the ambient temperature, and can also be determined by collecting images of the passenger compartment through a visual sensor, and determining the fogging risk level of the passenger compartment by identifying the collected images.

[0086] In the above embodiment, when it is determined that the temperature control instruction is the first temperature control instruction that requires simultaneous cooling and heating, the corresponding disabling heat pump mode determination condition is matched according to the first temperature control instruction, and it is not necessary to execute all the disabling heat pump mode determination conditions, thereby reducing the amount of data processing.

[0087] Further, when the temperature control demand parameter meets the first target determination condition, controlling the heat pump system to disable the heat pump dehumidification mode includes the following situations:

[0088] Case 1: When the first target judgment condition is the judgment condition for the compressor to operate beyond the boundary, when the ambient temperature is greater than or equal to the first ambient temperature threshold, the warm air core air volume is less than or equal to the first air volume threshold, and the target air outlet temperature is greater than or equal to the first air outlet temperature threshold, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0089] Exemplarily, when the ambient temperature ≥ the first ambient temperature threshold T1 (℃), the air volume through the warm air core ≤ the first air volume threshold V (kg / h), and the target air outlet temperature ≥ the first air outlet temperature threshold T2 (℃) are met at the same time, it can be understood that the judgment condition of the compressor's over-boundary operation is met. Under this operating condition, it is easy to cause the compressor to run over-boundary. Controlling the heat pump system to disable the heat pump dehumidification mode can avoid damage to the compressor and prevent the noise problem caused by the compressor running over-boundary. Among them, the first ambient temperature threshold T1, the first air volume threshold V, and the first air outlet temperature threshold T2 can be determined according to actual needs. For example, in an exemplary embodiment, the first ambient temperature threshold T1 can be 5℃, the first air volume threshold V can be 120kg / h, and the first air outlet temperature threshold T2 is 55℃. When the ambient temperature ≥5℃, the air volume through the warm air core ≤120kg / h, and the target air outlet temperature ≥55℃ are met at the same time, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0090] Case 2: When the first target judgment condition is that the heating demand is less than the preset value, resulting in frequent start and stop of the compressor, when the heating demand is less than or equal to the heating demand threshold and lasts for a first preset time, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0091] The heating demand can be determined by the heater core air volume*(target air outlet temperature-evaporator outlet side air temperature).

[0092] Exemplarily, if the heating demand threshold M is less than the heating demand through the warm air core air volume * (target outlet air temperature - evaporator outlet air temperature) and lasts for a period of time Ts1, that is, the first preset time, the heat pump related mode is prohibited, that is, the judgment condition that the heating demand is less than the preset value and the compressor is frequently started and stopped is met. Under this working condition, the use of the heat pump dehumidification mode may cause the compressor to be damaged by frequent start and stop, and the risk of the compressor starting and stopping causing the outlet air temperature to fluctuate and affect comfort. Disabling the heat pump related mode can avoid the problems caused by the frequent start and stop of the compressor. Among them, the heating demand threshold M and the first preset time Ts1 can be determined according to actual needs. For example, in an exemplary embodiment, the heating demand threshold M is 1800 and the first preset time Ts1 is 300s. If the heating demand * (target outlet air temperature - evaporator outlet air temperature) is less than 1800 and lasts for a period of time 300s, the heat pump dehumidification mode is prohibited.

[0093] Case 3: When the first target judgment condition is the judgment condition of frequent start and stop of the compressor, when the number of start and stop times of the compressor is greater than the number threshold, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0094] Exemplarily, if under the heat pump related mode operation condition, within the time period Ts3, the number of compressor starts and stops ≥ the number threshold N, that is, the judgment condition of frequent compressor starts and stops, then the heat pump system is controlled to disable the heat pump dehumidification mode. Further, after disabling the heat pump dehumidification mode, the heat pump related mode is not allowed to be used within the preset time Ts4. Controlling the heat pump system to disable the heat pump dehumidification mode can avoid the risk of frequent compressor starts and stops causing damage to the compressor, and the risk of the compressor start and stop causing the outlet temperature to fluctuate and affect comfort. Among them, the time period Ts3, the number threshold N and the preset time Ts4 can be determined according to actual needs. For example, in an exemplary embodiment, taking the time period Ts3 as 500s, the number threshold N as 3, and the preset time Ts4 as 900s as an example, if under the heat pump related mode operation condition, within the time period 500s, the number of compressor starts and stops ≥ 3, then the use of the disabled heat pump dehumidification mode is prohibited. And once it is determined that the heat pump dehumidification mode is disabled, the disabled heat pump dehumidification mode is not allowed to be used within a period of 900s.

[0095] Case 4: When the first target judgment condition is the judgment condition for preventing fogging of the passenger compartment, when the ambient temperature is greater than or equal to the second ambient temperature threshold, the internal circulation ratio is greater than the internal circulation ratio threshold and continues for a second preset time or the fogging risk level is greater than the preset level, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0096] Exemplarily, when (a) the ambient temperature ≥ the second ambient temperature threshold T2 (℃), (b) (the internal circulation ratio ≥ the internal circulation ratio threshold Z and lasts for a period of time Ts5, that is, the internal circulation ratio ≥ the internal circulation ratio threshold Z and lasts for a second preset time Ts5) or the passenger compartment fogging risk level is greater than the preset level, that is, when conditions (a) and (b) are met at the same time, it is determined that the judgment condition for preventing the passenger compartment from fogging is met, and the heat pump system is controlled to disable the heat pump dehumidification mode. This working condition can prevent the passenger compartment from fogging. Among them, the second ambient temperature threshold T2, the internal circulation ratio threshold Z and the duration Ts5 can be determined according to actual needs. In an exemplary embodiment, the second ambient temperature threshold T2 can be 3℃, the internal circulation ratio threshold Z can be 90% and the duration Ts5 can be 300s. When (a) the ambient temperature ≥ 3℃; (b) (the internal circulation ratio ≥ 90% and lasts for a period of time 300s, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0097] Case 5: When the first target judgment condition is the judgment condition for preventing fogging of the passenger compartment, when the evaporator outlet air temperature is less than or equal to the second outlet air temperature threshold or the fogging risk level is greater than the preset level, and the evaporator outlet air temperature is greater than or equal to the third outlet air temperature threshold and lasts for a third preset time period, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0098] Exemplarily, when (a) the evaporator outlet air temperature ≤ the second outlet air temperature threshold T3 (°C) or the passenger compartment fogging risk level is greater than the preset level, (b) the evaporator outlet air temperature ≥ the third outlet air temperature threshold T4 (°C), and lasts for the third preset time Ts6, and when (a) and (b) are satisfied at the same time, the heat pump system is controlled to disable the heat pump dehumidification mode. This operating condition can prevent the passenger compartment from fogging. Further, the heat pump dehumidification mode is not used within the preset time (for example, 900 seconds). Among them, the second outlet air temperature threshold T3, the third outlet air temperature threshold T4, and the third preset time Ts6 can be determined according to actual needs. In an exemplary embodiment, the second outlet air temperature threshold T3 can be 4°C, the third outlet air temperature threshold T4 can be 10°C, and the third preset time Ts6 can be 300s. When (a) the evaporator air outlet temperature is ≤4°C or the passenger compartment fogging risk level is greater than the preset level, and (b) the evaporator air outlet temperature is ≥10°C and lasts for 300s, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0099] Case six: When the first target judgment condition is the judgment condition of the normal operating boundary of the super heat pump system, when the ambient temperature is not within the preset ambient temperature range for the refrigerant to maintain a normal operating state, or the evaporator air outlet temperature is greater than or equal to the fourth air outlet temperature threshold, the heat pump system is controlled to disable the heat pump dehumidification mode.

[0100] It is understandable that when the ambient temperature is less than a certain value or greater than a certain value, the target heat pump mode cannot be operated. The ambient temperature is not within the preset ambient temperature range for the refrigerant to maintain a normal working state, which can be the ambient temperature ≤ the third ambient temperature threshold T5 (℃) or the ambient temperature ≥ the fourth ambient temperature threshold T6 (℃). For example, if the 134a model refrigerant is used to operate the heat pump related mode, when the ambient temperature is ≤-15℃, the low pressure of the refrigerant will be too low; when the ambient temperature is ≥20℃, the high pressure of the refrigerant will be too high.

[0101] Exemplarily, when the ambient temperature is ≤ the third ambient temperature threshold T5 (°C) or the ambient temperature is ≥ the fourth ambient temperature threshold T6 (°C), or the evaporator outlet air temperature is greater than or equal to the fourth outlet air temperature threshold T7 (°C), the heat pump system is controlled to disable the heat pump dehumidification mode. Under this condition, it is easy to exceed the normal operating boundary of the system using the target heat pump mode. Disabling the target heat pump mode can prevent damage to system components and prevent the compressor from starting and stopping to trigger the refrigerant pressure protection. Among them, the third ambient temperature threshold T5, the fourth ambient temperature threshold T6 and the fourth outlet air temperature threshold T7 can be determined according to actual needs. In an exemplary embodiment, the third ambient temperature threshold T5 can be -15°C, the fourth ambient temperature threshold T6 can be 15°C and the fourth outlet air temperature threshold T7 can be 35°C, the ambient temperature is ≤-15°C or the ambient temperature is ≥15°C, or the evaporator outlet air temperature is greater than or equal to 35°C, and the heat pump system is controlled to disable the heat pump dehumidification mode.

[0102] Optionally, in an exemplary embodiment, when the temperature control instruction is a first temperature control instruction requiring simultaneous cooling and heating, if the refrigerant side system fails, the heat pump dehumidification mode is prohibited. It is understandable that a system failure may cause the heat pump related functions to fail, and prohibiting the use of the heat pump dehumidification mode can ensure safety and energy saving.

[0103] In an exemplary embodiment, Figure 5 As shown, a heat pump mode control method is provided, including steps 502 to 504, wherein:

[0104] Step 502: When the temperature control instruction is a second temperature control instruction requiring heating, a matching second target determination condition is determined from preset determination conditions according to the first temperature control instruction.

[0105] Step 504: When the temperature control demand parameter meets the second target determination condition, the heat pump system is controlled to disable the heat pump heating mode.

[0106] The second target determination condition includes but is not limited to at least one of the following: the determination condition of compressor over-boundary operation, the determination condition of frequent compressor start-stop due to heating demand being less than a preset value, the determination condition of frequent compressor start-stop, and the determination condition of the normal operation boundary of the super heat pump system. The temperature control demand parameter includes at least one of ambient temperature, heater core air volume, target outlet air temperature, evaporator outlet air temperature, passenger compartment heating demand, compressor start-stop times within a preset period, internal circulation ratio, and fogging risk level.

[0107] In the above embodiment, when it is determined that the temperature control instruction is the second temperature control instruction requiring simultaneous cooling and heating, the corresponding disabling heat pump mode determination condition is matched according to the second temperature control instruction, and it is not necessary to execute all the disabling heat pump mode determination conditions, thereby reducing the amount of data processing.

[0108] Furthermore, when the temperature control demand parameter meets the second target determination condition, controlling the heat pump system to disable the heat pump heating mode includes the following situations:

[0109] Case 1: When the second target judgment condition is the judgment condition for the compressor to operate beyond the boundary, when the ambient temperature is greater than or equal to the first ambient temperature threshold, the heater core air volume is less than or equal to the first air volume threshold, and the target air outlet temperature is greater than or equal to the first air outlet temperature threshold, the heat pump system is controlled to disable the heat pump heating mode.

[0110] Exemplarily, when the ambient temperature ≥ the first ambient temperature threshold T1 (℃), the air volume passing through the warm air core ≤ the first air volume threshold V (kg / h), and the target air outlet temperature ≥ the first air outlet temperature threshold T2 (℃) are met at the same time, it can be understood that the judgment condition for the compressor to run beyond the boundary is met. Under this working condition, it is easy to cause the compressor to run beyond the boundary. Controlling the heat pump system to disable the heat pump heating mode can avoid damage to the compressor and prevent noise problems caused by the compressor running beyond the boundary. Among them, the first ambient temperature threshold T1, the first air volume threshold V, and the first air outlet temperature threshold T2 can be determined according to actual needs. For example, in an exemplary embodiment, the first ambient temperature threshold T1 can be 5℃, and the first air volume threshold V can be 120kg / h.

[0111] Case 2: When the second target judgment condition is that the heating demand is less than the preset value, resulting in frequent start and stop of the compressor, when the heating demand is less than or equal to the heating demand threshold and lasts for a first preset time, the heat pump system is controlled to disable the heat pump heating mode.

[0112] The heating demand can be determined by the heater core air volume*(target air outlet temperature-evaporator outlet side air temperature).

[0113] Exemplarily, if the air volume of the warm air core * (target outlet air temperature - evaporator outlet side air temperature) ≤ the heating demand threshold M, and lasts for a period of time Ts1, and Ts1 is within the preset demand duration, then the heat pump related modes are prohibited, that is, the judgment condition that the heating demand is less than the preset value, resulting in frequent start and stop of the compressor, is met. Under this working condition, the use of the heat pump dehumidification mode may cause the compressor to be damaged by frequent start and stop, and the risk of outlet temperature fluctuations affecting comfort due to the start and stop of the compressor. Disabling the heat pump heating mode can avoid problems caused by frequent start and stop of the compressor. Among them, the heating demand threshold M and the first preset duration Ts1 can be determined according to actual needs. For example, in an exemplary embodiment, the heating demand threshold M is 1800 and the first preset duration Ts1 is 300s.

[0114] Case 3: when the second target determination condition is the determination condition of frequent compressor starts and stops, when the number of compressor starts and stops is greater than the number threshold, the heat pump system is controlled to disable the heat pump heating mode.

[0115] Exemplarily, if in the heat pump related mode operating condition, within the time period Ts3, the number of compressor starts and stops ≥ the number threshold N, the heat pump system is controlled to disable the heat pump heating mode. Further, after disabling the heat pump heating mode, the heat pump related mode is not allowed to be used within the preset time Ts4. Among them, the time period Ts3, the number threshold N and the preset time Ts4 can be determined according to actual needs. For example, in an exemplary embodiment, the time period Ts3 is 500s, the number threshold N is 3, and the preset time Ts4 is 900s.

[0116] When the temperature control instruction is a second temperature control instruction requiring heating, controlling the heat pump system to disable the heat pump heating mode can avoid the risk of frequent starting and stopping of the compressor, which may cause the compressor to be damaged by using the heat pump heating mode, and the risk of air outlet temperature fluctuations affecting comfort due to frequent starting and stopping of the compressor.

[0117] Case 4: When the second target judgment condition is the judgment condition of the normal operating boundary of the super heat pump system, when the ambient temperature is not within the preset ambient temperature range for the refrigerant to maintain a normal operating state, or the evaporator air outlet temperature is greater than or equal to the fourth air outlet temperature threshold, the heat pump system is controlled to disable the heat pump heating mode.

[0118] Exemplarily, when the ambient temperature is less than or equal to the third ambient temperature threshold T5 (°C) or the ambient temperature is greater than or equal to the fourth ambient temperature threshold T6 (°C), or the evaporator outlet air temperature is greater than or equal to the fourth outlet air temperature threshold T7 (°C), the heat pump system is controlled to disable the heat pump dehumidification mode. It is understandable that under this condition, the use of the target heat pump mode can easily exceed the normal operating boundary of the system. Disabling the target heat pump mode can prevent damage to system components and prevent the compressor from starting and stopping to trigger the refrigerant pressure protection. Among them, the third ambient temperature threshold T5, the fourth ambient temperature threshold T6 and the fourth outlet air temperature threshold T7 can be determined according to actual needs. In an exemplary embodiment, the third ambient temperature threshold T5 can be -15°C, the fourth ambient temperature threshold T6 can be 15°C and the fourth outlet air temperature threshold T7 can be 35°C. Optionally, in an exemplary embodiment, when the temperature control instruction is a second temperature control instruction requiring heating, if the refrigerant side system fails, the heat pump heating mode is prohibited. It is understandable that system failure will cause the failure of heat pump related functions, and prohibiting the use of heat pump heating mode can ensure safety and energy saving.

[0119] In an exemplary embodiment, when a temperature control instruction to the passenger compartment initiated by the air-conditioning side is detected, the type of the temperature control instruction is determined. When the temperature control instruction is a first temperature control instruction requiring both cooling and heating, a matching first target determination condition is determined from preset determination conditions according to the first temperature control instruction; when the temperature control requirement parameter satisfies the first target determination condition, the heat pump system is controlled to disable the heat pump dehumidification mode. When the temperature control instruction is a second temperature control instruction requiring heating, a matching second target determination condition is determined from preset determination conditions according to the second temperature control instruction; when the temperature control requirement parameter satisfies the second target determination condition, the heat pump system is controlled to disable the heat pump heating mode.

[0120] It is understandable that the temperature control instruction is a first temperature control instruction that requires both cooling and heating or a second temperature control instruction that requires heating, and the corresponding judgment conditions can be achieved in the above manner, which will not be elaborated here. By judging and identifying each working condition, under the premise of ensuring system safety, no system noise, no risk of fogging in the passenger compartment and stable temperature control, the high-efficiency and energy-saving target heat pump mode is used to ensure the safety and stability of the heat pump system.

[0121] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0122] Based on the same inventive concept, the embodiment of the present application also provides a heat pump mode control device for implementing the heat pump mode control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more heat pump mode control device embodiments provided below can refer to the limitations of the heat pump mode control method above, and will not be repeated here.

[0124] The data acquisition module 602 is used to receive temperature control instructions for the passenger compartment and obtain temperature control demand parameters of the heat pump system.

[0125] The heat pump mode control module 604 is used to control the heat pump system to disable the target heat pump mode corresponding to the temperature control instruction when the temperature control demand parameter meets the preset judgment condition.

That is, when there is a temperature control requirement, it determines whether the heat pump system can execute the target heat pump mode according to the temperature control requirement parameters, determines the working conditions under which the heat pump system can operate normally, optimizes the operation of the heat pump system, and improves the stability and safety of the heat pump system.
