The embodiment of the invention provides an operation control method of a heat pump unit, and referring to fig. 2, fig. 2 is a flow chart of a first embodiment of the operation control method of the heat pump unit.
In this embodiment, the operation control method of the heat pump unit includes the following steps:
Step S10: and when the target energy requirement of the heat pump unit is larger than a preset energy requirement threshold, acquiring the succession of the heat pump unit for Wen Tingji times.
It should be noted that, the execution body of the method of this embodiment may be a device having a data acquisition or data processing function, for example: the control device of the heat pump unit may be other devices that can implement the same or similar functions, for example: the control device of the heat pump unit will be described in this embodiment and the following embodiments, with no particular limitation on this embodiment.
In this embodiment, the heat pump unit includes: the heat exchanger comprises a compressor 1, a water side heat exchanger 2, a four-way reversing valve 3, a throttling component 4, a heat source side heat exchanger 5 and a radiation end connected with the water side heat exchanger 2, wherein in the embodiment, referring to fig. 3, at least one radiation end is arranged on the heat exchange component of each action area, the heat exchange component can be a floor heating coil pipe, a radiation plate, a wind disc or a radiating fin and other equipment capable of realizing heat exchange with a heat pump cold and hot water unit, wherein the compressor 1 is used for controlling the temperature of a refrigerant in a pipeline of the heat pump unit, controlling the temperature of each heat exchanger, and further carrying out heat exchange with the outside to realize temperature rise or temperature reduction; the water side heat exchanger 2 is used for exchanging heat with water in an external water tank so as to control the external water temperature; the four-way reversing valve 3 is used for adjusting the flow direction of a refrigerant in the heat pump unit, and the valve position and the communication port of the four-way reversing valve 3 are different according to different operation modes of the heat pump unit; the throttle part 4 is used for controlling the flow speed of the refrigerant of the heat pump unit so as to control the speed of heat exchange with the external connection, the larger the opening of the throttle part 4 is, the faster the heat exchange is, the smaller the opening is, the slower the heat exchange is, and the throttle part is also used for releasing the pressure of the refrigerant so as to facilitate the form conversion of the refrigerant; the heat source side heat exchanger 5 is used to function as an evaporator or a condenser in different modes, and this embodiment is not particularly limited.
In a specific implementation, referring to fig. 4, fig. 4 is a structural block diagram of a heat pump unit proposed in this embodiment, where an output end of a compressor 1 is connected to a first communication port D of a four-way reversing valve 3, a second communication port C of the four-way reversing valve 3 is connected to a first end of a water side heat exchanger 2, a third communication port S of the four-way reversing valve 3 is connected to a second end of the compressor 1, a fourth communication port E of the four-way reversing valve 3 is connected to a first end of a heat source side heat exchanger 5, a second communication port of the water side heat exchanger 2 is connected to a second end of a throttling component 4, and a second end of the heat source side heat exchanger 5 is connected to a first end of the throttling component 4.
When the heat pump unit operates in a heating mode, referring to the solid line refrigerant flow direction in fig. 4, the compressor 1 operates to compress the refrigerant to obtain a high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is transmitted to the water side heat exchanger through the four-way reversing valve 3 under the pressure effect, at this time, the water side heat exchanger 2 serves as a condenser, after heat exchange with the water body in the water side heat exchanger 2, the water inlet temperature is lower than the water outlet temperature, thereby improving the temperature of the external water body, the refrigerant flows through the throttling part 4 in a high-pressure and medium-temperature state after passing through the water side heat exchanger 2, the refrigerant obtains a low-pressure and medium-temperature refrigerant through the throttling part 4 and flows through the heat source side heat exchanger 5, at this time, the heat source side heat exchanger 5 serves as an evaporator to obtain a low-temperature and low-pressure refrigerant, and finally, the refrigerant flows back to the compressor 1 through the four-way reversing valve 3 to complete the heating process, wherein in the heating process, the first communication port D and the second communication port C of the four-way reversing valve 3 are conducted to realize the refrigerant transportation to the water side heat exchanger 2 to condense, the refrigerant, the third communication port S and the fourth communication port E of the four-way reversing valve 3 are conducted, the refrigerant is used for recycling the refrigerant to the compressor 1 for compression at a time.
When the heat pump unit operates in a refrigeration mode, referring to the flow direction of a broken-line refrigerant in fig. 3, the compressor 1 operates to compress the internal refrigerant into a high-temperature and high-pressure refrigerant, the refrigerant is transported to the heat source side heat exchanger 5 through the four-way reversing valve 3, at this time, the heat source side heat exchanger 5 serves as a condenser to condense the refrigerant to obtain a medium-temperature and high-pressure refrigerant, the pressure is reduced by the throttling part 4 to obtain a low-pressure medium-temperature refrigerant, the refrigerant flows through the water side heat exchanger 2 to exchange heat, at this time, the hydrothermal heat exchanger 2 serves as an evaporator to absorb the heat of a water body, and then water body refrigeration is realized, and finally the four-way reversing valve 3 flows back to the compressor 1 to complete the refrigeration process, wherein in the refrigeration process, the first communication port D and the fourth communication port E of the four-way reversing valve 3 are conducted to realize the transportation of the refrigerant to the heat source side heat exchanger 5 for condensation, and the second communication port C and the third communication port S of the four-way reversing valve 3 are conducted for recycling the refrigerant to the compressor 1, and the next refrigerant compression is facilitated.
It can be understood that in the conventional technology, taking the refrigeration mode as an example, when the heat pump unit meets the target temperature reaching shutdown condition in the refrigeration mode, the preset starting platform number, the running frequency, the frequency raising speed, the platform stay running time, the energy requirement and other parameters are not changed, so that the refrigeration mode needs to be started again when the external temperature of the heat pump unit is raised, and the temperature is ensured to meet the refrigeration requirement of a user.
At this time, all parameters before stopping are unchanged, at this time, the restarting can lead to the air conditioner to refrigerate according to the parameters before stopping, however, in the prior art, the temperature difference between the temperature of the heat pump unit when the temperature reaching stopping is met and the temperature when restarting is not great, so that after restarting for a period of time, the heat pump system can stop because the temperature reaching stopping condition is met, and then the compressor is stopped, the repeated stopping restarting can lead to the shortening of the service life of the compressor, and the unstable indoor temperature control can also be caused, and a large amount of electric energy is wasted.
In order to solve the problems, the method of the embodiment realizes the control of the operation frequency of the compressor by adjusting the energy requirement when the heat pump system is restarted, prolongs the time when the temperature meets the temperature reaching stop condition, further avoids the repeated restarting of the compressor in a short time, prolongs the service life and enhances the stability and the reliability of the heat pump unit.
It should be understood that the target energy requirement may refer to a target load of the heat pump unit, and the preset energy requirement threshold may be 0, that is, when the target energy requirement of the heat pump unit is greater than 0, the heat pump unit is obtained for Wen Tingji times continuously, so as to correct the target energy requirement of the heat pump unit when the heat pump unit meets the restart condition.
Further, in order to accurately obtain the continuous reaching Wen Tingji times of the heat pump unit, the continuous operation duration of the heat pump unit can be obtained when the heat pump system meets the target reaching temperature stop condition; when the continuous operation time length is smaller than the preset time length, counting by a counter until Wen Tingji, and obtaining the count value of the counter; and determining the succession of the heat pump unit for Wen Tingji times according to the count value.
It should be noted that, the target temperature reaching shutdown condition relates to an operation mode of the heat pump unit, and generally, the temperature and the shutdown time are taken as determination conditions, for example: in the cooling mode, the temperature set by the user is 23 ℃, so that the heat pump unit can meet the target temperature-reaching shutdown condition when the room temperature is reduced to 23 ℃ within 10 minutes due to heat dissipation and other reasons, and the embodiment does not limit the temperature specifically.
It is easy to understand that the continuous operation duration refers to the operation duration of the heat pump unit when the heat pump unit starts to reach a temperature and stops, and after each stop, the continuous operation duration is cleared, for example: and starting the heat pump unit at 8:00, and stopping the heat pump unit at 8:10 until the temperature is reached, wherein the continuous operation time is 10 minutes.
In a specific implementation, the preset duration is used for judging whether the heat pump unit is a time basis for repeatedly restarting in a short time, for example: the preset time length is set to be 15 minutes, the continuous operation time length of the heat pump unit is 10 minutes, and the shutdown is judged to be the time condition of repeated start and stop in a short time.
In a specific implementation, the timer is cleared when the compressor starts to operate so as to facilitate subsequent continuous operation time counting, in this embodiment, the counter adds 1 to the accounting number when the continuous operation time is less than 15 minutes, and the timer is cleared so as to prepare for subsequent re-counting, but the counter is not cleared, and the counter is cleared when the continuous operation time is not less than 15 minutes.
It should be noted that, the step of determining the number of times of continuous temperature shutdown is determined according to the count value of the counter, and the larger the count value is, the larger the subsequent correction is, and the more correction is needed, the user's use requirement cannot be met, and the user experience is affected, so that the correction is performed according to the allowable maximum needed after the number of times of continuous shutdown reaches a certain number.
Further, in order to avoid the influence of excessive correction energy on the operation state of the heat pump unit, when the count value is not smaller than a second preset shutdown threshold value, the continuous temperature reaching shutdown frequency of the heat pump unit can be corrected to the second preset threshold value; and when the count value is smaller than a second preset shutdown threshold value, determining continuous temperature reaching shutdown times according to the difference value of the count value and a preset constant.
It should be noted that, in this embodiment, the second preset shutdown threshold may be set to 4 or 5 times, and for example, when the count value is greater than 4, the count value is corrected to 4, so as to avoid the problem of insufficient energy requirement caused by excessive correction, which is not limited in this embodiment.
The preset constant may be set to 1, that is, when the count value is less than 4, subtracting 1 from the count value is performed as a succession of Wen Tingji times, for example: the second preset shutdown threshold may be set to 4 as an example, when the count value of the counter is 5, the number of times of continuous up to Wen Tingji is corrected to 4, and when the count value of the counter is 3, the number of times of continuous up to temperature shutdown is corrected to 2.
Further, before the heat pump system meets the target temperature reaching shutdown condition and the continuous operation duration of the heat pump unit is obtained, the method further includes:
Acquiring a current operation mode of the heat pump unit;
determining the operating frequency of the compressor according to the target energy;
And controlling the running state of the compressor according to the running frequency and the current running mode until the heat pump unit meets the temperature reaching stop condition in the current running mode.
It should be noted that, because the temperature reaching stop conditions in different operation modes are different, in judging whether the heat pump unit meets the temperature reaching stop condition in the target current operation mode, the target temperature set by the user in the action area of the heat pump unit can be considered, where the action area of the heat pump unit refers to the space where the radiation end is located.
Further, the controlling the operation state of the compressor according to the operation frequency and the current operation mode until the heat pump unit meets the temperature reaching stop condition in the current operation mode includes:
Acquiring the current ambient temperature of an action area of the heat pump system;
when the current operation mode is a refrigeration mode, controlling the operation state of the compressor according to the operation frequency until the current environment temperature is less than or equal to a first preset temperature threshold; and
And when the current operation mode is a heating mode, controlling the operation state of the compressor according to the operation frequency until the current environment temperature is greater than or equal to a second preset temperature threshold.
It may be appreciated that there is no determined magnitude relation between the first preset temperature threshold and the second preset temperature threshold, where the first preset temperature threshold in the cooling mode may be 26 ℃ and the second preset temperature threshold in the heating mode may be 18 ℃, which is not particularly limited in this embodiment.
In addition, if there are multiple acting areas of the same heat pump unit, the selection of the temperature threshold in the cooling mode or heating mode may be comprehensively determined according to the temperatures set by the user in each acting area, for example: in the cooling mode, the setting of the first preset temperature threshold may be a minimum value of the user-set temperature of each action area, and in the heating mode, the setting of the second preset temperature threshold may be a maximum value of the user-set temperature of each action area, which is not particularly limited in this embodiment.
Step S20: and when the continuous temperature-reaching shutdown times are not smaller than a first preset shutdown threshold, updating the target energy requirement according to the continuous temperature-reaching shutdown times.
It will be appreciated that in this embodiment, the first preset shutdown threshold may be set to 2, or may be other times, which is not specifically limited in this embodiment.
In the specific implementation, when the continuous temperature-reaching shutdown frequency of the heat pump unit is more than 2, the situation of repeated restarting is judged, and the energy needs to be updated, so that equipment is prevented from being damaged.
It should be noted that, the process of updating the target energy requirement of the heat pump unit according to the continuous reaching temperature shutdown times may be determined according to the energy requirement correction policy corresponding to the current operation mode, and the energy requirement correction policy may be determined by referring to a correction formula of qwc=qn (1-c×e), where Qwc is the target energy requirement after correction, C is the reaching temperature shutdown times in the refrigeration mode, E is a correction coefficient, and Qn is the target energy requirement.
Step S30: and determining the operation frequency of the compressor in the heat pump unit according to the updated target energy.
In this embodiment, the greater the updated target energy is, the greater the corresponding compressor operating frequency; the smaller the updated target energy is required, the smaller the corresponding compressor operating frequency.
Step S40: and controlling the operation state of the heat pump unit based on the compressor operation frequency.
In specific implementation, referring to fig. 5 and 6, fig. 5 and 6 are schematic diagrams of control logic capable of correcting and adjusting an operation state of the heat pump unit under a heating operation and a cooling operation of the heat pump unit, where C is a cooling reaching temperature stop frequency, H is a heating reaching temperature stop frequency, n is a cooling forced starting platform number, m is a heating forced starting platform number, C is a cooling count value, H is a heating count value, timec is a cooling operation duration, timeh is a heating operation duration, qwc is a cooling energy requirement, and Qwh is a heating energy requirement.
According to the embodiment, by acquiring the continuous reaching Wen Tingji times of the heat pump unit, when the continuous reaching temperature stopping times are larger than the first preset stopping threshold, the target energy requirement of the heat pump unit is updated according to the continuous reaching temperature stopping times, so that the problem that when the heat pump unit is restarted when reaching temperature stopping, the heat pump unit is rapidly stopped again due to overlarge target energy requirement, the operation effect of the heat pump unit is influenced, the operation frequency of a compressor in the heat pump unit is required to be controlled by the updated target energy, the operation influence of the overlarge energy requirement on a heat pump system is reduced, the technical problems that the compressor is frequently restarted due to unsuitable operation parameters when reaching temperature stopping and restarting of the heat pump unit in the prior art are solved, and the reliability and stability of the heat pump unit are improved.
Referring to fig. 7, fig. 7 is a schematic flow chart of a second embodiment of an operation control method of a heat pump unit according to the present invention.
Based on the first embodiment, in this embodiment, the step S20 includes:
step S201: and acquiring the operation mode and the target energy requirement of the heat pump unit.
It should be noted that, the operation mode of the heat pump unit may be a cooling mode or a heating mode, and the target energy may be a target load amount that needs to be carried by the heat pump unit, for example: for the central air conditioner, the target energy requirement can be determined according to the number of rooms and the number of devices for starting the air conditioner, the more the rooms for starting the air conditioner are, the larger the target energy requirement is, the fewer the rooms for starting the air conditioner are, and the smaller the target energy requirement is, so that the embodiment is not particularly limited.
Step S202: and determining parameters which can be corrected according to the operation mode.
In this embodiment, the correction coefficient is used to combine with the number of consecutive temperature-up and down times when the energy demand correction is performed later, so as to determine the energy demand value that needs to be reduced.
The correction parameters may be set to different parameters according to different operation modes, and the value ranges of the correction parameters are 0-100%, so that for convenience of explanation, in the embodiment, the correction coefficients required in the refrigeration mode and the heating mode are 20%, and the embodiment is not limited specifically.
Step S203: and updating the target energy requirement of the heat pump unit according to the continuous temperature reaching stop times and the energy requirement correction parameters.
In a specific implementation, when the heat pump unit operates in the refrigeration mode, a formula for updating the target energy requirement of the heat pump unit according to the continuous temperature reaching shutdown times and the energy requirement correction parameters is as follows:
Qwc＝Qn(1-C*E)
Wherein Qwc is the target energy demand after correction, C is the number of times of temperature reaching and stopping in the cooling mode, E is the correction coefficient in the cooling mode, and Qn is the target energy demand in the cooling mode.
When the heat pump unit operates in a heating mode, updating a formula of target energy requirement of the heat pump unit according to the continuous reaching temperature stop times and the energy requirement correction parameters, wherein the formula comprises the following steps:
Qwh＝Qn(1-H*F)
Wherein Qwh is the target energy demand after correction, H is the number of times of temperature reaching and stopping in the heating mode, F is the correction coefficient in the heating mode, and Qn is the target energy demand in the heating mode.
The embodiment discloses obtaining an operation mode and target energy requirements of the heat pump unit; determining parameters which can be corrected according to the operation mode; according to the continuous temperature reaching and stopping times and the energy demand correction parameters, the target energy demand of the heat pump unit is updated, and the energy demand correction coefficients in all operation modes are determined according to the operation modes of the heat pump unit, so that the target energy demand of the heat pump system is updated according to different operation modes and corresponding energy demand correction coefficients, further, the target energy demand of the heat pump unit when the heat pump unit is restarted again after the temperature reaching and stopping is reduced, the occurrence of the situation of repeated restarting in a short time is avoided, and the reliability and the stability of the heat pump unit are enhanced.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium is stored with an operation control program of the heat pump unit, and the operation control program of the heat pump unit realizes the steps of the operation control method of the heat pump unit when being executed by a processor.
Because the storage medium adopts all the technical schemes of all the embodiments, the storage medium has at least all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted here.
Referring to fig. 8, fig. 8 is a block diagram showing the construction of a first embodiment of an operation control device of a heat pump unit according to the present invention.
As shown in fig. 8, an operation control device of a heat pump unit according to an embodiment of the present invention includes:
And the acquisition module 10 is used for acquiring the succession of Wen Tingji times of the heat pump unit when the target energy requirement of the heat pump unit is larger than a preset energy requirement threshold.
In this embodiment, the heat pump unit includes: the heat pump unit comprises a compressor 1, a water side heat exchanger 2, a four-way reversing valve 3, a throttling component 4 and a heat source side heat exchanger 5, wherein the compressor 1 is used for controlling the temperature of a refrigerant in a pipeline of the heat pump unit, controlling the temperature of each heat exchanger, and further carrying out heat exchange with the outside to realize temperature rise or temperature reduction; the water side heat exchanger 2 is used for exchanging heat with water in an external water tank so as to control the external water temperature; the four-way reversing valve 3 is used for adjusting the flow direction of a refrigerant in the heat pump unit, and the valve position and the communication port of the four-way reversing valve 3 are different according to different operation modes of the heat pump unit; the throttle part 4 is used for controlling the flow speed of the refrigerant of the heat pump unit so as to control the speed of heat exchange with the external connection, the larger the opening of the throttle part 4 is, the faster the heat exchange is, the smaller the opening is, the slower the heat exchange is, and the throttle part is also used for releasing the pressure of the refrigerant so as to facilitate the form conversion of the refrigerant; the heat source side heat exchanger 5 is used to function as an evaporator or a condenser in different modes, and this embodiment is not particularly limited.
In a specific implementation, referring to fig. 3, fig. 3 is a structural block diagram of a heat pump unit proposed in this embodiment, where an output end of a compressor 1 is connected to a first communication port D of a four-way reversing valve 3, a second communication port C of the four-way reversing valve 3 is connected to a first end of a water side heat exchanger 2, a third communication port S of the four-way reversing valve 3 is connected to a second end of the compressor 1, a fourth communication port E of the four-way reversing valve 3 is connected to a first end of a heat source side heat exchanger 5, a second communication port of the water side heat exchanger 2 is connected to a second end of a throttling part 4, and a second end of the heat source side heat exchanger 5 is connected to a first end of the throttling part 4.
When the heat pump unit operates in a heating mode, referring to the solid line refrigerant flow direction in fig. 3, the compressor 1 operates to compress the refrigerant to obtain a high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is transmitted to the water side heat exchanger through the four-way reversing valve 3 under the pressure effect, at this time, the water side heat exchanger 2 serves as a condenser, after heat exchange with the water body in the water side heat exchanger 2, the water inlet temperature is lower than the water outlet temperature, thereby improving the temperature of the external water body, the refrigerant flows through the throttling part 4 in a high-pressure and medium-temperature state after passing through the water side heat exchanger 2, the refrigerant obtains a low-pressure and medium-temperature refrigerant through the throttling part 4 and flows through the heat source side heat exchanger 5, at this time, the heat source side heat exchanger 5 serves as an evaporator to obtain a low-temperature and low-pressure refrigerant, and finally, the refrigerant flows back to the compressor 1 through the four-way reversing valve 3 to complete the heating process, wherein in the heating process, the first communication port D and the second communication port C of the four-way reversing valve 3 are conducted to realize the refrigerant transportation to the water side heat exchanger 2 to condense, the refrigerant, the third communication port S and the fourth communication port E of the refrigerant are conducted for recycling the refrigerant to the compressor 1, and the refrigerant is convenient for the compression.
When the heat pump unit operates in a refrigeration mode, referring to the flow direction of a broken-line refrigerant in fig. 3, the compressor 1 operates to compress the internal refrigerant into a high-temperature and high-pressure refrigerant, the refrigerant is transported to the heat source side heat exchanger 5 through the four-way reversing valve 3, at this time, the heat source side heat exchanger 5 serves as a condenser to condense the refrigerant to obtain a medium-temperature and high-pressure refrigerant, the pressure is reduced by the throttling part 4 to obtain a low-pressure medium-temperature refrigerant, the refrigerant flows through the water side heat exchanger 2 to exchange heat, at this time, the hydrothermal heat exchanger 2 serves as an evaporator to absorb the heat of a water body, and then water body refrigeration is realized, and finally the four-way reversing valve 3 flows back to the compressor 1 to complete the refrigeration process, wherein in the refrigeration process, the first communication port D and the fourth communication port E of the four-way reversing valve 3 are conducted to realize the transportation of the refrigerant to the heat source side heat exchanger 5 for condensation, and the second communication port C and the third communication port S of the four-way reversing valve 3 are conducted for recycling the refrigerant to the compressor 1, and the next refrigerant compression is facilitated.
It can be understood that in the conventional technology, taking the refrigeration mode as an example, when the heat pump unit meets the target temperature reaching shutdown condition in the refrigeration mode, the preset starting platform number, the running frequency, the frequency raising speed, the platform stay running time, the energy requirement and other parameters are not changed, so that the refrigeration mode needs to be started again when the external temperature of the heat pump unit is raised, and the temperature is ensured to meet the refrigeration requirement of a user.
At this time, all parameters before stopping are unchanged, at this time, the restarting can lead to the air conditioner to refrigerate according to the parameters before stopping, however, in the prior art, the temperature difference between the temperature of the heat pump unit when the temperature reaching stopping is met and the temperature when restarting is not great, so that after restarting for a period of time, the heat pump system can stop because the temperature reaching stopping condition is met, and then the compressor is stopped, the repeated stopping restarting can lead to the shortening of the service life of the compressor, and the unstable indoor temperature control can also be caused, and a large amount of electric energy is wasted.
In order to solve the problems, the method of the embodiment realizes the control of the operation frequency of the compressor by adjusting the energy requirement when the heat pump system is restarted, prolongs the time when the temperature meets the temperature reaching stop condition, further avoids the repeated restarting of the compressor in a short time, prolongs the service life and enhances the stability and the reliability of the heat pump unit.
It should be understood that the target energy requirement may refer to a load of the heat pump unit, and the preset energy requirement threshold may be 0, that is, when the target energy requirement of the heat pump unit is greater than 0, the heat pump unit is obtained for Wen Tingji times continuously, so as to correct the target energy requirement of the heat pump unit when the heat pump unit meets the restart condition.
Further, in order to accurately obtain the continuous reaching Wen Tingji times of the heat pump unit, the continuous operation duration of the heat pump unit can be obtained when the heat pump system meets the target reaching temperature stop condition; when the continuous operation time length is smaller than the preset time length, counting by a counter until Wen Tingji, and obtaining the count value of the counter; and determining the succession of the heat pump unit for Wen Tingji times according to the count value.
It should be noted that, the target temperature reaching shutdown condition relates to an operation mode of the heat pump unit, and generally, the temperature and the shutdown time are taken as determination conditions, for example: in the cooling mode, the temperature set by the user is 23 ℃, so that the heat pump unit can meet the target temperature-reaching shutdown condition when the room temperature is reduced to 23 ℃ within 10 minutes due to heat dissipation and other reasons, and the embodiment does not limit the temperature specifically.
It is easy to understand that the continuous operation duration refers to the operation duration of the heat pump unit when the heat pump unit starts to reach a temperature and stops, and after each stop, the continuous operation duration is cleared, for example: and starting the heat pump unit at 8:00, and stopping the heat pump unit at 8:10 until the temperature is reached, wherein the continuous operation time is 10 minutes.
In a specific implementation, the preset duration is used for judging whether the heat pump unit is a time basis for repeatedly restarting in a short time, for example: the preset time length is set to be 15 minutes, the continuous operation time length of the heat pump unit is 10 minutes, and the shutdown is judged to be a time condition of repeated restarting in a short time.
In a specific implementation, the timer is cleared when the compressor starts to operate so as to facilitate subsequent continuous operation time counting, in this embodiment, the counter adds 1 to the accounting number when the continuous operation time is less than 15 minutes, and the timer is cleared so as to prepare for subsequent re-counting, but the counter is not cleared, and the counter is cleared when the continuous operation time is not less than 15 minutes.
It should be noted that, the step of determining the number of times of continuous temperature shutdown is determined according to the count value of the counter, and the larger the count value is, the larger the subsequent correction is, and the more correction is needed, the user's use requirement cannot be met, and the user experience is affected, so that the correction is performed according to the allowable maximum needed after the number of times of continuous shutdown reaches a certain number.
Further, in order to avoid the influence of excessive correction energy on the operation state of the heat pump unit, when the count value is not smaller than a second preset shutdown threshold value, the continuous temperature reaching shutdown frequency of the heat pump unit can be corrected to the second preset threshold value; and when the count value is smaller than a second preset shutdown threshold value, determining continuous temperature reaching shutdown times according to the difference value of the count value and a preset constant.
It should be noted that, in this embodiment, the second preset shutdown threshold may be set to 4 or 5 times, and for example, when the count value is greater than 4, the count value is corrected to 4, so as to avoid the problem of insufficient energy requirement caused by excessive correction, which is not limited in this embodiment.
The preset constant may be set to 1, that is, when the count value is less than 4, subtracting 1 from the count value is performed as a succession of Wen Tingji times, for example: the second preset shutdown threshold may be set to 4 as an example, when the count value of the counter is 5, the number of times of continuous up to Wen Tingji is corrected to 4, and when the count value of the counter is 3, the number of times of continuous up to temperature shutdown is corrected to 2.
Further, before the heat pump system meets the target temperature reaching shutdown condition and the continuous operation duration of the heat pump unit is obtained, the method further includes:
Acquiring a current operation mode of the heat pump unit;
determining the operating frequency of the compressor according to the target energy;
And controlling the running state of the compressor according to the running frequency and the current running mode until the heat pump unit meets the temperature reaching stop condition in the current running mode.
It should be noted that, because the temperature reaching stop conditions in different operation modes are different, it is judged whether the heat pump unit meets the temperature reaching stop conditions in the target current operation mode.
And the correction module 20 is configured to update the target energy requirement according to the continuous temperature-reaching shutdown times when the continuous temperature-reaching shutdown times are not less than a first preset shutdown threshold.
It will be appreciated that in this embodiment, the first preset shutdown threshold may be set to 2, or may be other times, which is not specifically limited in this embodiment.
In the specific implementation, when the continuous temperature-reaching shutdown frequency of the heat pump unit is more than 2, the situation of repeated restarting is judged, and the energy needs to be updated, so that equipment is prevented from being damaged.
It should be noted that, the process of updating the target energy requirement of the heat pump unit according to the continuous reaching temperature shutdown times may be determined according to the energy requirement correction policy corresponding to the current operation mode, and the energy requirement correction policy may be determined by referring to a correction formula of qwc=qn (1-c×e), where Qwc is the target energy requirement after correction, C is the reaching temperature shutdown times in the refrigeration mode, E is a correction coefficient, and Qn is the target energy requirement.
And the control module 30 is used for determining the operation frequency of the compressor in the heat pump unit according to the updated target energy.
In this embodiment, the greater the updated target energy is, the greater the corresponding compressor operating frequency; the smaller the updated target energy is required, the smaller the corresponding compressor operating frequency.
The control module 40 is further configured to control an operation state of the heat pump unit based on the compressor operation frequency.
In specific implementation, referring to fig. 4 and fig. 5, fig. 4 and fig. 5 are schematic diagrams of control logic capable of correcting and adjusting an operation state of the heat pump unit under a heating operation and a cooling operation of the heat pump unit, where C is a cooling reaching temperature stop frequency, H is a heating reaching temperature stop frequency, n is a cooling forced starting platform number, m is a heating forced starting platform number, C is a cooling count value, H is a heating count value, timec is a cooling operation duration, timeh is a heating operation duration, qwc is a cooling energy requirement, and Qwh is a heating energy requirement.
According to the embodiment, by acquiring the continuous reaching Wen Tingji times of the heat pump unit, when the continuous reaching temperature stopping times are larger than the first preset stopping threshold, the target energy requirement of the heat pump unit is updated according to the continuous reaching temperature stopping times, so that the problem that when the heat pump unit is restarted when reaching temperature stopping, the heat pump unit is rapidly stopped again due to overlarge target energy requirement, the operation effect of the heat pump unit is influenced, the operation frequency of a compressor in the heat pump unit is required to be controlled by the updated target energy, the operation influence of the overlarge energy requirement on a heat pump system is reduced, the technical problems that the compressor is frequently restarted due to unsuitable operation parameters when reaching temperature stopping and restarting of the heat pump unit in the prior art are solved, and the reliability and stability of the heat pump unit are improved.
