Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling a zone temperature, including:
step S110, comparing target temperatures in the temperature control command, determining a target peak value, defining a region corresponding to the target peak value as a master region, and defining other regions as slave regions, wherein the target peak value is the lowest cooling temperature or the highest heating temperature;
step S120, operating according to the temperature control instruction corresponding to the main area, and controlling the air valve in each area to rotate to a fully open state;
step S130, acquiring the current temperatures of a plurality of areas in real time, and judging whether the areas reach the corresponding target temperatures according to the current temperature and the target temperature of each area;
step S140, when the master area does not reach the corresponding target temperature of the master area and the slave area reaches the corresponding target temperature of the slave area, adjusting the opening degree of an air valve of the slave area according to the running frequency of a compressor and the environmental parameters corresponding to the slave area so as to keep the temperature of the slave area at the corresponding target temperature, and returning to the step of acquiring the current temperatures of the plurality of areas in real time;
and S150, when the main area reaches the corresponding target temperature, adjusting the operating frequency of the compressor according to the maximum temperature difference of the target temperatures of the plurality of areas, and adjusting the opening of the air valve according to the adjusted operating frequency of the compressor and the environmental parameters of each area so as to keep the temperature of the slave area at the corresponding target temperature.
In this embodiment, a user selects an opening area and obtains a target temperature set in the opening area through the area temperature control device, and when the opening area is selected, the air valve corresponding to the area is powered on, and the air valve rotates to a fully open state. Specifically, the temperature control device may be an air valve controller, and the air valve controller is used to implement each step of the zone temperature control method. The temperature control instruction is generated through a control terminal, and the control terminal is used for realizing a human-computer interaction function and specifically can be a touch display screen and the like.
When the system is set to cooling mode: the current target temperature minimum value is set as a target peak value, the corresponding area is set as a main area, other areas are set as slave areas, and the control system executes a cooling instruction according to the target temperature set by the main area. When the system is set to the heating mode: the maximum value of the current target temperature is set as a target peak value, the corresponding area is set as a main area, other areas are set as slave areas, and the control system executes a heating instruction according to the target temperature set by the main area. When the air valve is selected to be opened, the air valve is rotated to a full-open state, and when the main area does not reach the target fixed temperature and the rest of any area reaches the target temperature, the opening degree of the air valve in the area reaching the target temperature is reduced to the opening degree of the air valve matched with the current target temperature. And after the main area reaches the target temperature, adjusting the target operating frequency F of the compressor according to the maximum difference value delta T between the target temperatures of the areas, and simultaneously reducing the opening of each air valve to the opening of the air valve matched with the air valve opening matching coefficient calculated by the system according to the current latest compressor frequency and the environmental parameters so as to keep the room temperature at the target temperature.
Specifically, when the system operates in the cooling mode, the target temperature of the main area is the lowest, and generally, the time required for reaching the target temperature is longer, so that the cooling instruction is executed at the target temperature set by the main area, and it can be ensured that all the areas can reach the target temperature. And when the main area reaches the corresponding target temperature, the operation frequency of the compressor is adjusted according to the maximum temperature difference value of the target temperatures of the plurality of areas, and the opening degree of the air valve is adjusted according to the adjusted operation frequency of the compressor and the environmental parameters of each area so as to keep the temperature of the auxiliary area at the corresponding target temperature, thereby realizing accurate control of the temperature and effectively solving the problem that the target temperature cannot be reached due to the large temperature difference when the targets of the areas are inconsistent because the same air pipe is shared.
In one embodiment, the zone temperature control method further includes:
acquiring a changed temperature control instruction, wherein the changed temperature control instruction comprises a changed target temperature corresponding to an area reaching the target temperature and the area identification information;
judging whether the changed target temperature is larger than the current target peak value;
if so, operating according to the changed temperature instruction, taking the corresponding area as a changed main area, and returning to the step of acquiring the current temperatures of the areas in real time;
otherwise, changing the air valve opening degree of the area so as to enable the temperature of the area to reach and maintain the changed target temperature.
It can be understood that after the cooling or heating mode is started, the preliminarily set target temperature may not meet the somatosensory requirement, and the target temperature needs to be reset. For example, when the current system is operating in a cooling mode, the target temperature of the main area is 25 ℃, and the target temperature of other areas is higher than 25 ℃; if the current temperature in the slave area is maintained at 27 ℃ as the target temperature, but the exercise time is reached, the temperature of the slave area needs to be reduced in order to avoid a large amount of sweating, so that the target temperature of the slave area is changed to 23 ℃ through the control terminal. At this time, the target temperature after the change from the zone is lower than the current target temperature, and if the system still performs cooling according to the current target temperature, the zone whose target temperature is set to 23 ℃ does not reach the target temperature. At this time, it is necessary to set 23 ℃ as the target peak value, set the current master region corresponding to the target temperature of 25 ℃ as the slave region, and set the slave region having the target temperature of 23 ℃ as the master region, so that the system executes the cooling command according to the changed target temperature of the master region, and dynamically adjust the air valves of the other regions, thereby realizing accurate control of the temperature.
In addition, if the target temperature after the change of the slave area is 26 ℃, the target temperature is still higher than the current target temperature of the master area and is higher than the temperature of the cold air sent out from the air pipe, so that the temperature of the slave area can be reduced to 26 ℃ from the original 27 ℃ only by increasing the opening degree of the air valve and increasing the input amount of the cold air at the moment.
In one embodiment, the adjusting the operating frequency of the compressor according to the maximum temperature difference of the target temperatures of the plurality of zones includes:
calculating the maximum temperature difference of the target temperatures of the plurality of areas according to a plurality of target temperatures;
according to the maximum temperature difference value, determining a target operation frequency by searching a comparison table of the operation frequency of the compressor and the temperature difference;
adjusting the frequency of the compressor to the target operating frequency.
TABLE 1 comparison table of compressor running frequency and temperature difference
| ΔT≥6℃ | F＝F1-(F1-F2)/2 |
| 6℃＞ΔT＞3℃ | F＝F1-(F1-F2)/4 |
| 3℃≥ΔT≥1℃ | F＝F1 |
In this embodiment, adjusting the operating frequency of the compressor according to the maximum temperature difference of the target temperatures of the plurality of zones specifically includes: and calculating the maximum temperature difference value according to the maximum target temperature value and the minimum target area value, namely, the maximum temperature difference value is delta T-Tmax, Tmax is the maximum target temperature value, and Tmin is the minimum target temperature value. Then, by looking up a comparison table of the operating frequency of the compressor and the temperature difference, as shown in the above table 1, a target operating frequency of the compressor is determined, and then the operating frequency F of the compressor is modulated according to the target operating frequency.
In one embodiment, adjusting the opening degree of the damper according to the operating frequency of the compressor and the environmental parameter includes:
calculating a formula air valve opening matching coefficient according to the running frequency of the compressor, the environmental parameter and a preset air valve opening matching coefficient;
determining the opening degree of the air valve according to the matching coefficient of the opening degree of the air valve;
and adjusting the air valve of the slave area according to the determined air valve opening.
In this embodiment, a user opens any room air valve through the control terminal, and sets the room air conditioning mode and temperature. The information storage module in the zone temperature control device stores the environmental parameters corresponding to each zone, including the room area, the room orientation and the number of the standing people. Analyzing the room environment parameters input by the user, comprising: the method comprises the steps of calculating air valve opening degree matching coefficients of all air valve areas capable of maintaining set temperature according to room area, room orientation, the number of people living in the room, current time and outdoor temperature and current compressor operation frequency, and storing an initial matching coefficient table corresponding to the air valve opening degree in an air valve controller in advance. When an indoor air conditioner is opened, an air valve of a certain room is fully opened, after the temperature of the room is detected to reach a set temperature, an air valve controller reduces the opening degree of the air valve of the room to the opening degree of the air valve corresponding to a matching coefficient capable of maintaining the set temperature, meanwhile, the current temperature data of the room is collected in real time, an angle sensor installed on the air valve is connected with the air valve controller, the current temperature change of the room collected at the moment is responded, a closed loop feedback system is formed, and the air valve can reach the accurate opening degree capable of maintaining the set temperature. The range of the opening degree of the air valve is 0-90 degrees, 0 degree is in a fully closed state, and 90 degrees is in a fully open state.
In one embodiment, in the cooling mode, the calculation formula of the matching coefficient of the opening degree of the air valve is as follows:
s＝f1(δN+δS+δT+δM-δF)
wherein S is an air valve opening matching coefficient, δ N is a human number influence factor, δ S is a house face sub-influence factor, δ M room orientation and an influence factor generated at the current moment, δ F is a current compressor frequency influence factor, δ T is an outdoor temperature influence factor, and F1 is a calculation function in a refrigeration mode.
It can be understood that the house environment parameters comprise fixed influence factors and variable influence factors, and the influence proportion of each influence factor is different. The fixed influence factors comprise a personnel number influence factor delta N and a house area influence factor delta S, the change influence factors comprise an outdoor temperature influence factor delta T and a current compressor frequency influence factor delta F, and the room orientation and the influence factor delta M generated at the current moment. The influence factors M of the house orientation and the current moment and the influence factors M of the outdoor temperature are in direct proportion to the opening of the air valve, and the influence factors of the compressor frequency and the opening of the air valve are in inverse proportion. The influence factors generated by the house orientation and the current time are different according to the difference between the house orientation and the current time, such as: if the house faces east, the influence factor of the morning time is larger than the influence factor of the afternoon time, and if the house faces west, the influence factor of the morning time is smaller than the influence factor of the afternoon time.
In one embodiment, in the heating mode, the calculation formula of the matching coefficient of the opening degree of the air valve is as follows:
s＝f2(δN+δS-δT-δM-δF)
wherein S is an air valve opening matching coefficient, δ N is a human number influence factor, δ S is a house face sub-influence factor, δ M room orientation and an influence factor generated at the current moment, δ F is a current compressor frequency influence factor, δ T is an outdoor temperature influence factor, and F2 is a calculation function in a heating mode.
According to a calculation formula of the air valve opening matching coefficient in the heating mode, the personnel number influence factor, the house area influence factor and the compressor frequency influence factor are in direct proportion to the air valve opening, and the house orientation and the influence factor generated at the current moment, the compressor frequency influence factor and the outdoor temperature influence factor are in inverse proportion to the air valve opening. The influence factor M generated by the house orientation and the current time is different according to two rules, such as: if the house faces east, the morning impact factor is smaller than the afternoon impact factor, and if the house faces west, the morning impact factor is larger than the afternoon impact factor.
In one embodiment, the determining the air valve opening according to the air valve opening matching coefficient includes:
and finding out the air valve opening corresponding to the air valve opening matching coefficient from a preset mapping relation table.
It can be understood that the corresponding relationship of the air valve opening corresponding to the air valve opening matching coefficient is calculated in advance to form a mapping relationship table and stored in the database, as shown in table 2, so that the corresponding air valve opening can be directly and quickly found in the control process according to the mapping relationship and the known air valve opening matching coefficient, and the control response is improved. Further, the damper opening degree may also be calculated by modeling. In this embodiment, when the system is running, it is calculated that the matching coefficient s of the opening of the air valve belongs to a certain coefficient section in the initial matching table, and when the temperature of the room reaches the set temperature, the opening of the air valve is reduced to the size of the opening of the air valve corresponding to the matching coefficient s of the opening of the air valve
TABLE 2 air valve opening degree and air valve opening degree matching coefficient mapping table
| Matching coefficient | Opening degree of air valve |
| [s1,s2) | θ1＝5° |
| [s2,s3) | θ2＝10° |
| [s3,s4) | θ3＝15° |
| … | … |
| [s15,s16) | θ16＝80° |
| [s16,s17) | θ17＝85° |

In one embodiment, the zone temperature control method further includes:
before the temperature control instructions of a plurality of zones are obtained, the environmental parameters corresponding to each zone are obtained and stored, wherein the environmental parameters comprise the room area size, the room orientation and the number of the standing persons in the room. In addition, the environmental parameter is the current time and the outdoor temperature.
In one embodiment, the zone temperature control method further includes:
before acquiring temperature control instructions of a plurality of areas, judging whether the number of the opened areas is equal to 1;
if the number of the areas is equal to 1, acquiring a temperature control instruction of the areas and executing;
and acquiring the current temperature of the area in real time, and adjusting the opening degree of an air valve of the area according to the operating frequency of the compressor and the environmental parameters corresponding to the area when the current temperature of the area reaches the target temperature of the area so as to keep the temperature of the area at the corresponding target temperature.
It is understood that when only one zone is turned on to cool/heat, the cooling/heating command of the zone may be directly executed. Specifically, when the number X of the open areas is 1, the current open area is set as the main area by the system, the control system opens the cooling/heating mode according to the current set target temperature instruction, and when the room temperature fed back by the temperature sensor in the room temperature controller reaches a set value, the air valve controller decreases the air valve opening corresponding to the matching coefficient calculated by the system to maintain the set temperature of the room, so as to maintain the room temperature at the set temperature.
In one embodiment, the zone temperature control method further comprises recording the current environmental parameters, the target temperature and the opening degree of the air valve capable of maintaining the constant temperature, and storing the current environmental parameters, the target temperature and the opening degree of the air valve as a calculation reference of the system to the opening degree of the air valve controller.
Based on the same inventive concept, the embodiment of the present invention further provides a zone temperature control apparatus 10, please refer to fig. 2, where the zone temperature control apparatus 10 includes an obtaining module 110, a comparing module 120, and an executing module 130.
The obtaining module 110 is configured to obtain temperature control instructions of a plurality of zones, and obtain current temperatures of the plurality of zones in real time.
The comparison module 120 is configured to compare target temperatures in the temperature control instruction, determine a target peak value, define a region corresponding to the target peak value as a master region, and define other regions as slave regions, where the target peak value is a minimum cooling temperature or a maximum heating temperature; and judging whether the area reaches the corresponding target temperature or not according to the current temperature and the target temperature of each area.
The execution module 130 is configured to, when the master area does not reach the target temperature corresponding to the master area and the slave area reaches the target temperature corresponding to the slave area, adjust an opening degree of an air valve of the slave area according to an operating frequency of the compressor and an environmental parameter corresponding to the slave area to maintain the temperature of the slave area at the target temperature corresponding to the slave area, and return to the step of acquiring the current temperatures of the plurality of areas in real time; and when the main area reaches the corresponding target temperature of the main area, adjusting the operating frequency of the compressor according to the maximum temperature difference of the target temperatures of the plurality of areas, and adjusting the opening of the air valve according to the adjusted operating frequency of the compressor and the environmental parameters of each area so as to keep the temperature of the slave area at the corresponding target temperature.
In this embodiment, a user selects an opening area and obtains a target temperature set by the opening area through the control terminal, and when the opening area is selected, the air valve corresponding to the area is powered on, and the air valve rotates to a fully open state. Specifically, the temperature control device may be a damper controller, and the obtaining module 110, the comparing module 120 and the executing module 130 are integrated in the damper controller. The temperature control instruction is generated through a control terminal, and the control terminal realizes a human-computer interaction function and can be a touch display screen and the like
When the system is set to cooling mode: the current target temperature minimum value is set as a target peak value, the corresponding area is set as a main area, other areas are set as slave areas, and the control system executes a cooling instruction according to the target temperature set by the main area. When the system is set to the heating mode: the maximum value of the current target temperature is set as a target peak value, the corresponding area is set as a main area, other areas are set as slave areas, and the control system executes a heating instruction according to the target temperature set by the main area. When the air valve is selected to be opened, the air valve is rotated to a full-open state, and when the main area does not reach the target fixed temperature and the rest of any area reaches the target temperature, the opening degree of the air valve in the area reaching the target temperature is reduced to the opening degree of the air valve matched with the current target temperature. And after the main area reaches the target temperature, adjusting the target operating frequency F of the compressor according to the maximum difference value delta T between the target temperatures of the areas, and simultaneously reducing the opening of each air valve to the opening of the air valve matched with the air valve opening matching coefficient calculated by the system according to the current latest compressor frequency and the environmental parameters so as to keep the room temperature at the target temperature.
Specifically, when the system operates in the cooling mode, the target temperature of the main area is the lowest, and generally, the time required for reaching the target temperature is longer, so that the cooling instruction is executed at the target temperature set by the main area, and it can be ensured that all the areas can reach the target temperature. And when the main area reaches the corresponding target temperature, the operation frequency of the compressor is adjusted according to the maximum temperature difference value of the target temperatures of the plurality of areas, and the opening degree of the air valve is adjusted according to the adjusted operation frequency of the compressor and the environmental parameters of each area so as to keep the temperature of the auxiliary area at the corresponding target temperature, thereby realizing accurate control of the temperature and effectively solving the problem that the target temperature cannot be reached due to the large temperature difference when the targets of the areas are inconsistent because the same air pipe is shared.
In one embodiment, the obtaining module 110 is further configured to obtain a modified temperature control command, where the modified temperature control command includes a modified target temperature corresponding to an area where the target temperature has been reached and the area identification information.
The comparing module 120 is further configured to determine whether the modified target temperature is greater than the current target peak value.
The execution module 130 is further configured to operate according to the changed temperature instruction when the changed target temperature is greater than the current target peak value, take the corresponding region as a changed main region, and return to the step of acquiring the current temperatures of the plurality of regions in real time; and changing the air valve opening degree of the area when the changed target temperature is less than or equal to the current target peak value so that the temperature of the area reaches and is maintained at the changed target temperature.
It can be understood that after the cooling or heating mode is started, the preliminarily set target temperature may not meet the somatosensory requirement, and the target temperature needs to be reset. For example, when the current system is operating in a cooling mode, the target temperature of the main area is 25 ℃, and the target temperature of other areas is higher than 25 ℃; if the current temperature in the slave area is maintained at 27 ℃ as the target temperature, but the exercise time is reached, the temperature of the slave area needs to be reduced to avoid a large amount of sweating, so that the target temperature of the slave area is changed to 23 ℃ through the control terminal, and a changed temperature control command is generated. At this time, the target temperature after the change from the zone is lower than the current target temperature, and if the system still performs cooling according to the current target temperature, the zone whose target temperature is set to 23 ℃ does not reach the target temperature. At this time, it is necessary to set 23 ℃ as the target peak value, set the current master region corresponding to the target temperature of 25 ℃ as the slave region, and set the slave region having the target temperature of 23 ℃ as the master region, so that the system executes the cooling command according to the changed target temperature of the master region, and dynamically adjust the air valves of the other regions, thereby realizing accurate control of the temperature.
In addition, if the target temperature after the change of the slave area is 26 ℃, the target temperature is still higher than the current target temperature of the master area and is higher than the temperature of the cold air sent out from the air pipe, so that the temperature of the slave area can be reduced to 26 ℃ from the original 27 ℃ only by increasing the opening degree of the air valve and increasing the input amount of the cold air at the moment.
In one embodiment, the executing module 130 for adjusting the opening degree of the damper according to the operating frequency of the compressor and the environmental parameter is specifically configured to:
calculating a formula air valve opening matching coefficient according to the running frequency of the compressor, the environmental parameter and a preset air valve opening matching coefficient;
determining the opening degree of the air valve according to the matching coefficient of the opening degree of the air valve;
and adjusting the air valve of the slave area according to the determined air valve opening.
It is understood that the information storage module in the zone temperature control device 10 stores the environmental parameters corresponding to each zone. Analyzing the room environment parameters input by the user, comprising: the method comprises the steps of calculating air valve opening degree matching coefficients of all air valve areas capable of maintaining set temperature according to room area, room orientation, the number of people living in the room, current time and outdoor temperature and current compressor operation frequency, and storing an initial matching coefficient table corresponding to the air valve opening degree in an air valve controller in advance. When an indoor air conditioner is opened, an air valve of a certain room is fully opened, after the temperature of the room is detected to reach a set temperature, an air valve controller reduces the opening degree of the air valve of the room to the opening degree of the air valve corresponding to a matching coefficient capable of maintaining the set temperature, meanwhile, the current temperature data of the room is collected in real time, an angle sensor installed on the air valve is connected with the air valve controller, the current temperature change of the room collected at the moment is responded, a closed loop feedback system is formed, and the air valve can reach the accurate opening degree capable of maintaining the set temperature. The range of the opening degree of the air valve is 0-90 degrees, 0 degree is in a fully closed state, and 90 degrees is in a fully open state. The house environment parameters comprise fixed influence factors and variable influence factors, and influence proportions of the fixed influence factors and the variable influence factors are different. The fixed influence factors comprise a personnel number influence factor delta N and a house area influence factor delta S, the change influence factors comprise an outdoor temperature influence factor delta T and a current compressor frequency influence factor delta F, and the room orientation and the influence factor delta M generated at the current moment. Therefore, in calculating the damper opening degree matching coefficient, the environmental parameter may not be ignored.
In one embodiment, in the cooling mode, the calculation formula of the matching coefficient of the opening degree of the air valve is as follows:
s＝f1(δN+δS+δT+δM-δF)；
in the heating mode, the calculation formula of the air valve opening matching coefficient is as follows:
s＝f2(δN+δS-δT-δM-δF)
wherein S is an air valve opening matching coefficient, δ N is a human number influence factor, δ S is a house face sub-influence factor, δ M room orientation and an influence factor generated at the current moment, δ F is a current compressor frequency influence factor, an outdoor temperature influence factor, F1 is a calculation function in a refrigeration mode, and F2 is a calculation function in a heating mode.
According to a calculation formula of the air valve opening matching coefficient in the refrigeration mode, the influence factor of the number of people, the influence factor of the area of the house, the influence factor M generated by the house orientation and the current moment, the influence factor of the outdoor temperature and the opening of the air valve are in direct proportion, and the influence factor of the frequency of the compressor and the opening of the air valve are in inverse proportion. The influence factors generated by the house orientation and the current time are different according to the difference between the house orientation and the current time, such as: if the house faces east, the influence factor of the morning time is larger than the influence factor of the afternoon time, and if the house faces west, the influence factor of the morning time is smaller than the influence factor of the afternoon time. According to a calculation formula of the air valve opening matching coefficient in the heating mode, the personnel number influence factor, the house area influence factor and the compressor frequency influence factor are in direct proportion to the air valve opening, and the house orientation and the influence factor generated at the current moment, the compressor frequency influence factor and the outdoor temperature influence factor are in inverse proportion to the air valve opening. The influence factor M generated by the house orientation and the current time is different according to two rules, such as: if the house faces east, the morning impact factor is smaller than the afternoon impact factor, and if the house faces west, the morning impact factor is larger than the afternoon impact factor.
