Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner and a building control system capable of realizing the control method.
Background
The conventional air conditioning system has a plurality of energy-saving control modes, but generally requires manual operation to select a corresponding energy-saving control mode, and the main way to realize the energy-saving control mode is to limit the maximum output of the outdoor unit.
Therefore, the energy-saving control mode of the air conditioning system in the prior art has two problems, namely, the setting needs to be manually operated, the energy-saving control mode cannot be automatically recovered after the setting is carried out, and the operation needs to be manually operated again to recover the original operation mode. Secondly, the energy-saving control mode at present only achieves the purpose of saving energy by limiting the maximum output of the outdoor unit, and the use experience of users is sacrificed by the control method.
In addition, the total output demand of the central air conditioners in a certain building, a certain cell and other areas changes along with time, taking an office building as an example, the daily working hours are usually the peak hours of the output demand of the air conditioners in the office building, and the output demand is relatively low at other times. The relationship between the output demand of the air conditioner of the apartment building and the time period is opposite to that of the air conditioner of the apartment building. Because there are many factors affecting the output requirement of the air conditioner, it is troublesome to manually set the output that varies with time, but there is no accurate method for evaluating the output requirement at present.
In summary, it is an object of the prior art to provide an air conditioner control method capable of more accurately evaluating the time-varying output demand of an air conditioner in an area such as a building or a cell, so as to intelligently control the air conditioner to enter or exit an energy-saving control mode.
Disclosure of Invention
In view of the above problems, the present invention provides an air conditioner control method capable of more accurately evaluating the output demand of an air conditioner in an area such as a building, a community, etc. which changes with time, thereby intelligently controlling the air conditioner to enter or exit an energy saving control mode, including: a detection step S1 of acquiring the total number of the illumination lamps located in the area as first number information, and acquiring the number of the illumination lamps located in the area in an off state as second number information; a calculating step S2, calculating the closing rate of the illuminating lamps in the area according to the first quantity information and the second quantity information; the control step S3 is to generate a control command to control the output of the air conditioners located in the area according to the lighting lamp turn-off rate.
In the process of creating the present invention, the inventor finds that there is a high correlation between the lighting lamp turn-off rate in areas such as buildings, districts and the like (especially office buildings) and the output requirement of the air conditioner, and the output requirement of the air conditioner is low when the lighting lamp turn-off rate is high, and the output requirement of the air conditioner is high when the lighting lamp turn-off rate is low. Therefore, the control system of the air conditioner can control the output of the air conditioner more intelligently by providing a communication connection with the lighting lamp system and an output control method based on the turn-off rate of the lighting lamp.
According to the technical scheme provided by the invention, the total number of the illuminating lamps in the area is recorded as first quantity information, the first quantity information is a fixed value in a long period of time, the number of the illuminating lamps in the off state in the area is recorded as second quantity information, and the second quantity information is a variable value due to the influence of personnel activities in the area. Further, the second amount of information is continuously recorded during the day, and the second amount of information shows a gradually rising trend and/or a gradually falling trend with the passage of time.
Wherein a ratio of the second quantity information representing the number of the illumination lamps in the off state in the area to the first quantity information representing the total number of the illumination lamps in the area is an illumination lamp off rate in the area. The closing rate of the illuminating lamp can accurately reflect the output requirement degree of the air conditioner in the area, and accordingly, the control instruction is automatically generated to control the output of the air conditioner in the area, so that the output of the air conditioner is intelligently controlled according to the actual requirement of a user.
Examples of the method for controlling the output of the air conditioner include: controlling the output power or output current of the outdoor units, controlling the number of the outdoor units in operation, controlling the number of the indoor units in operation, controlling the target temperature of the indoor units, and the like.
In a preferred embodiment of the present invention, the controlling step S3 includes: in the first control step S31, when the lighting lamp turn-off rate is greater than the first threshold, an energy saving control command is generated to reduce the output of the air conditioners located in the area.
According to the better technical scheme, when the number of the illuminating lamps in the off state in the area shows a gradually rising trend, especially when the number of the illuminating lamps in the off state accounts for a certain proportion of the total number of the illuminating lamps, namely the off rate of the illuminating lamps is greater than a first threshold value, the energy-saving control instruction is automatically generated. Since it is known from the increasing rate of lamp turn-off that the demand for air conditioning in the area is decreasing, a higher lamp turn-off rate indicates that only a lower air conditioning output is required to meet the demand of personnel in the area. At the moment, the output of the air conditioner in the area can be reduced, so that the energy-saving effect can be achieved, and the use experience of the user cannot be influenced.
In a preferred embodiment of the present invention, the controlling step S3 further includes: and a timing step S32, after the air conditioner executes the energy-saving control instruction, monitoring the energy-saving control time t.
According to the better technical scheme, the output is reduced after the air conditioner receives the energy-saving control instruction, but the use experience of a user can be influenced if the energy-saving control time t is too long, and if the energy-saving control time t is too short, the energy-saving effect is difficult to play, and the operation burden of the air conditioner can be additionally increased by adjusting the output of the air conditioner for multiple times in a short time. Therefore, according to the preferred technical scheme, a limit is set for the energy-saving control time t by monitoring the energy-saving control time t, so that the aim of saving energy is fulfilled, and meanwhile, the change of the demands of personnel in the area can be considered.
In a preferred embodiment of the present invention, the controlling step S3 further includes: in the second control step S33, when the energy saving control time t reaches the predetermined time, the current lighting lamp turn-off rate is obtained again, and the turn-off control command or the recovery control command is selectively generated according to the current lighting lamp turn-off rate.
According to the preferred technical scheme, the energy-saving control time t reaches the specified time, which indicates that the air conditioner has been operated at a lower output for a period of time, and the output size of the air conditioner is adjusted again according to the demands of the people in the area, so that the output of the air conditioner is matched with the demands of the people in the area. The current lighting lamp turn-off rate refers to a lighting lamp turn-off rate in the area after the air conditioner executes the energy saving control command for a predetermined time period, and the relation between the lighting lamp turn-off rate in the first control step S31 is as follows: and in the same area, the turn-off rate of the illuminating lamps at different time points. The lamp turn-off rate in the first control step S31 is used to determine whether to generate an energy-saving control command, and the current lamp turn-off rate in the second control step S33 is used to determine whether to generate a turn-off control command or a recovery control command after executing the energy-saving control command for a prescribed period of time.
In a preferred embodiment of the present invention, the second control step S33 further includes: when the current turn-off rate of the illuminating lamps is greater than a first threshold value, a turn-off control instruction is generated so as to turn off the output of the air conditioners located in the area; and when the current closing rate of the illuminating lamp is smaller than a second threshold value, generating a recovery control instruction so as to recover the output of the air conditioner in the area.
According to this preferred solution, the current rate of lamp switching off being greater than the first threshold value indicates that the degree of use of the area by the personnel is low and that such a condition has persisted for a longer period of time. The output of the air conditioner in the area can be closed according to the judgment, so that the intelligent control of the air conditioner is realized. Similarly, the current turn-off rate of the lighting lamp is smaller than the second threshold value, which indicates that the use degree of the area by the personnel is increased, the output demand of the air conditioner is increased, and the output under the energy-saving control instruction is difficult to meet the demand of the personnel in the area, so that the recovery control instruction needs to be generated. The resume control command is a command for resuming the output of the air conditioner to a state before the execution of the energy saving control command, which corresponds to the completion of the execution of the energy saving control command. By adopting the recovery control instruction, the user personalized requirements can be considered while the automatic entering or exiting of the energy-saving control is realized.
And when the illumination turn-off rate is smaller than the first threshold and larger than the second threshold, the air conditioner keeps outputting currently, namely keeps executing the energy-saving control instruction.
In a preferred technical scheme of the present invention, the energy saving control command is: and adjusting the target value of the indoor unit refrigerating and evaporating temperature from a first value to a second value, wherein the second value is larger than the first value, or/and adjusting the target value of the indoor unit heating and condensing temperature from a third value to a fourth value, wherein the fourth value is smaller than the third value. Further, the closing control command is: turning off air conditioners located in the area; the recovery control command is: and adjusting the target value of the indoor unit refrigeration evaporation temperature from a second value to a first value, or/and adjusting the target value of the indoor unit heating condensation temperature from a fourth value to a third value.
According to the better technical scheme, the target value of the refrigeration evaporation temperature of the indoor unit or/and the target value of the heating condensation temperature of the indoor unit is/are adjusted, so that the energy-saving control instruction only aims at the indoor unit in the area with the illumination turn-off rate larger than the first threshold value, and the use experience of users in other areas is not influenced.
The invention also provides a computer readable storage medium, which stores a computer program, and when the computer program is read and run by a processor, the control method of the air conditioner in any technical scheme is realized.
The invention also provides a building control system, comprising:
a lighting module including a plurality of lighting lamps;
the detection module is used for acquiring the total number information of the illuminating lamps in the building and the number information of the illuminating lamps in the off state in the building;
the control module receives the total number information and the quantity information, calculates to obtain the turn-off rate of the illuminating lamps, and generates a control instruction according to the turn-off rate of the illuminating lamps;
and the air conditioner module is used for controlling the output of the air conditioner positioned in the building according to the control instruction.
According to the technical scheme provided by the invention, the air conditioner module can be adjusted according to the lighting turn-off rate of the lighting module through the detection module and the control module, so that the air conditioner can be intelligently controlled to enter or exit the energy-saving control mode according to the use condition of a user. The detection module can transmit the total number information of the illuminating lamps and the number information of the illuminating lamps in the off state to the control module through wired or wireless communication.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be modified as needed by those skilled in the art to suit particular applications. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
In the embodiment of the present invention, the term "area" is not limited according to the size of a space or whether the spaces are connected in a physical sense, but is generally an area using a unified air conditioning control system and lighting control system, which may be a community, a building in the community, a floor in the building, or one or more rooms.
Referring to fig. 1, the present embodiment provides an air conditioner control method capable of more accurately evaluating the time-varying output demand of an air conditioner in an area such as a building, a cell, etc., thereby intelligently controlling an air conditioning system to enter or exit an energy saving control mode, including: a detection step S1 of acquiring the total number of the illumination lamps located in the area as first number information, and acquiring the number of the illumination lamps located in the area in an off state as second number information; a calculating step S2, calculating the closing rate of the illuminating lamps in the area according to the first quantity information and the second quantity information; the control step S3 is to generate a control command to control the output of the air conditioners located in the area according to the lighting lamp turn-off rate.
According to the present embodiment, the total number of lights located in an area is recorded as first quantity information that is constant for a long period of time, for example, ten lights in a building. And recording the number of the illuminating lamps in the off state in the area as second quantity information, wherein the second quantity information is a change value due to the influence of the activities of the personnel in the area. Further, the second amount of information is continuously recorded during the day, and the second amount of information may show a gradually rising trend and/or a gradually falling trend with the passage of time. For example, in the morning, when people start to enter the first building of the A building, the illuminating lamps in the first building are gradually turned on, and the number of the illuminating lamps in the first building of the A building in the turned-off state tends to decrease; during the noon break, part of people leave the first building A, part of the illuminating lamps are gradually turned off, and the number of the illuminating lamps in the first building A in the turned-off state tends to increase in the period.
The ratio of the second quantity information representing the number of illumination lamps in the off state within the area to the first quantity information representing the total number of illumination lamps within the area is the illumination lamp off rate within the area. The closing rate of the illuminating lamp can accurately reflect the output requirement degree of the air conditioner in the area, and accordingly, the control instruction is automatically generated to control the output of the air conditioner in the area, and the output of the air conditioner can be intelligently controlled according to the actual requirement of a user.
It can be understood that as long as the output of the air conditioner in the area is controlled according to the turn-off rate of the illuminating lamps in the area, the air conditioner can be intelligently controlled to enter or exit the energy-saving control mode according to the use condition of the user.
The air conditioner can be a multi-split air conditioner (a plurality of indoor units correspond to one outdoor unit), a ducted air conditioner (one indoor unit corresponds to one outdoor unit) or any other structure which can be called as an air conditioner; a zone may refer to a room or office, a portion of a floor, an entire floor, or an entire building; the number of the illuminating lamps in the area is not limited, at least one illuminating lamp in one room can be used, and at most hundreds of illuminating lamps in the whole building can be used; examples of ways to control the output of the air conditioner are: controlling the output power or output current of the outdoor units, controlling the number of the outdoor units in operation, controlling the number of the indoor units in operation, controlling the target temperature of the indoor units, and the like.
Preferably, the air conditioner in the present embodiment is a multi-split air conditioning system in an office building, and it is understood that the office building is different from a home building, and outdoor lighting cannot provide illumination to the office building even in the daytime, so that an illumination lamp is required to be turned on in the used area of the office building from the morning to the evening. In other words, the turn-off rate of the illuminating lamps can reflect the activity of people in the area. Of course, it can be understood by those skilled in the art that although the office building is taken as an example, the solutions provided in some embodiments can be applied to the areas such as apartment buildings and residential areas, and the solutions are not limited to only using the turn-off rate of the illumination lamps as a reference, and the output of the multi-split air conditioning system can be comprehensively set based on multiple factors such as external light intensity and time.
Referring to fig. 2, in a preferred embodiment, when the turn-off rate of the lighting lamps in the area is greater than a first threshold, the air conditioner will execute an energy saving control command to implement automatic entering of energy saving control. After the air conditioner enters the energy-saving mode and reaches the set time, the control mode before the air conditioner is turned off, keeps the energy-saving control or is recovered is determined according to the current lighting lamp turn-off rate. Specifically, the control step S3 includes: in the first control step S31, when the lighting lamp turn-off rate is greater than the first threshold value, an energy saving control command is generated to reduce the output of the air conditioners located in the zone. And a timing step S32, after the air conditioner executes the energy-saving control instruction, monitoring the energy-saving control time t. In the second control step S33, when the energy saving control time t reaches the predetermined time, the current lighting lamp turn-off rate is obtained again, and the turn-off control command or the recovery control command is selectively generated according to the current lighting lamp turn-off rate.
According to the preferred embodiment, a gradually increasing rate of lamp turn-off generally indicates that demand for air conditioners in the area is gradually decreasing, and a higher rate of lamp turn-off indicates that only a lower air conditioner output is required to meet the demand of personnel in the area. At the moment, the output of the air conditioner in the area is reduced, so that the energy-saving effect can be achieved, and the use experience of the user cannot be influenced. However, the use experience of the user may be affected by the too long energy-saving control time t, and if the energy-saving control time t is too short, the energy-saving effect is difficult to be achieved, and the operation burden of the air conditioner is additionally increased by adjusting the output of the air conditioner for many times in a short time. Thus, according to a preferred embodiment, by monitoring the energy saving control time t, a limit is set for the energy saving control time t to ensure that the ever changing needs of the personnel in the area are met while the energy saving objective is achieved. When the energy-saving control time t reaches the specified time, the air conditioner works for a period of time at a lower output, and the output size of the air conditioner is adjusted again according to the requirements of personnel in the area, so that the output of the air conditioner is matched with the requirements of the personnel in the area, and the changing requirements of users are met.
Further, when the current lighting lamp turn-off rate is greater than a first threshold value, a turn-off control instruction is generated to turn off the output of the air conditioners located in the area; and when the current closing rate of the illuminating lamp is smaller than a second threshold value, generating a recovery control instruction so as to recover the output of the air conditioner in the area.
As an example, when the people in building a enter noon at 11 pm, all or part of the people leave building a and turn off the lighting lamps, the lighting off rate in building a will therefore exceed a first threshold (preferably 65% -80%), and an energy saving control command is generated to reduce the output of the air conditioner located in building a. And after the air conditioner executes the energy-saving control instruction, monitoring the energy-saving control time t, and when the energy-saving control time t reaches a specified time (preferably, the specified time is 120 minutes), reacquiring the current turn-off rate of the illuminating lamp. At the moment, the noon break time is over, the illuminating lamps in the first building of the building A are turned on, the current closing rate of the illuminating lamps is reduced to be smaller than a second threshold value (preferably, the second threshold value is 35% -45%), and a recovery control instruction is generated at the moment, so that the automatic exit of the energy-saving control is realized.
As another example, when a person in building a arrives at the next hour at 17 pm, all or part of the persons leave building a and turn off the illumination lamps, the illumination turn-off rate in building a will thus exceed a first threshold, and an energy saving control command is generated to reduce the output of the air conditioners located in building a. And after the air conditioner executes the energy-saving control instruction, monitoring the energy-saving control time t, and when the energy-saving control time t reaches the specified time, acquiring the current turn-off rate of the illuminating lamp again. At this time, the time is about 19 pm, compared with 17 pm, the number of the illuminating lamps in the off state in the first building of the building a is increased, the current closing rate of the illuminating lamps still exceeds the first threshold value, and at this time, a closing control instruction is generated, so that the air conditioner is automatically closed.
In other words, when the closing rates of the two acquired illuminating lamps are both greater than the first threshold, the area is judged to be in the off-duty time at the moment, the demand of the area on the air conditioner is zero, and a closing control instruction is generated and executed. And when the closing rate of the lighting lamp acquired for the first time is greater than a first threshold value and the closing rate of the lighting lamp acquired for the second time is less than a second threshold value, judging that the area is in normal working time after noon break, increasing the demand of the area on the air conditioner, and generating and executing a recovery control instruction.
In a preferred embodiment, the output of the air conditioner is controlled by controlling a target temperature of the indoor unit. Specifically, the energy-saving control instruction is as follows: and adjusting the target value of the indoor unit refrigeration evaporation temperature from a first value to a second value, wherein the second value is larger than the first value, or/and adjusting the target value of the indoor unit heating condensation temperature from a third value to a fourth value, wherein the fourth value is smaller than the third value. Further, the closing control command is: turning off air conditioners located in the area; the recovery control command is: and adjusting the target value of the indoor unit refrigeration evaporation temperature from a second value to a first value, or/and adjusting the target value of the indoor unit heating condensation temperature from a fourth value to a third value.
According to the better technical scheme, the target value of the refrigeration evaporation temperature of the indoor unit or/and the target value of the heating condensation temperature of the indoor unit is/are adjusted, so that the energy-saving control instruction only aims at the indoor unit in the area with the illumination turn-off rate larger than the first threshold value, and the use experience of users in other areas is not influenced. For example, indoor units in a first building and a second building of the A building are connected with the same outdoor unit, people in the first building of the A building enter the noon break at 11 noon, part of people leave the first building of the A building, the lighting off rate in the first building of the A building exceeds a first threshold value, and the target value of the refrigeration evaporation temperature of the indoor units in the first building of the A building is adjusted from 25 ℃ to 28 ℃. Meanwhile, the noon break time of the people in the second building of the building A is 12, and at this time, if the outdoor unit is adjusted to perform energy-saving control, the use experience of the people in the second building of the building A is influenced.
The execution of the return control command corresponds to returning the output of the air conditioner to the state before the execution of the energy saving control command. By adopting the recovery control instruction, the user personalized requirements can be considered while the automatic entering or exiting of the energy-saving control is realized. For example, people in the first building of the building A are used to adjust the target value of the refrigeration evaporation temperature to 25 ℃, when a part of people leave the first building of the building A in the afternoon, and the lighting off rate in the first building of the building A exceeds a first threshold value, the air conditioner executes an energy-saving control instruction to adjust the target value of the refrigeration evaporation temperature to 28 ℃ so as to achieve the purpose of energy saving. And after the noon break, when the current lighting off rate in the first building of the A building is at a second threshold value, the air conditioner executes a recovery control instruction, and the target value of the refrigeration evaporation temperature is recovered to 25 ℃ so as to meet the habit of personnel in the first building of the A building.
The present embodiment also provides a computer-readable storage medium storing a computer program, which is read by a processor and executed to implement the method for controlling an air conditioner in the present embodiment.
Referring to fig. 3, the present embodiment also provides a building control system 10 including:
a lighting module 1 including a plurality of lighting lamps;
the detection module 2 is used for acquiring the total number information of the illuminating lamps in the building and the number information of the illuminating lamps in the off state in the building;
the control module 3 receives the total number information and the quantity information, calculates to obtain the turn-off rate of the illuminating lamps, and generates a control instruction according to the turn-off rate of the illuminating lamps;
and the air conditioner module 4 is used for controlling the output of the air conditioner in the building according to the control instruction.
According to the technical scheme provided by the embodiment, the lighting module 1 and the air conditioner module 4 are linked through the detection module 2 capable of detecting the total number of the lighting lamps and the on-off state of the lighting lamps and the control module 3 capable of controlling the output of the air conditioner, so that the air conditioner can be intelligently controlled to enter or exit the energy-saving control mode according to the use condition of a user. The detection module 2 may transmit the total number information of the lighting lamps and the number information of the lighting lamps in the off state to the control module 3 through wired or wireless communication.
The illuminating lamp can be controlled to be turned on or off by a mechanical switch, and preferably, the illuminating lamp is automatically controlled to be turned on or off according to infrared detection. In this way, when a person in the area leaves, the infrared detection device on the illuminating lamp automatically turns off after detecting that no person exists in the area, and the turn-off rate of the illuminating lamp in the area is increased, so that a control instruction for controlling the air conditioner module 4 is generated. Due to the infrared detection device on the illuminating lamp, the situation that the control module 3 sends out an instruction which is not in accordance with the actual situation because the lamp is forgotten to be turned off is avoided.
As an example, a plurality of illuminating lamps and air conditioners are arranged in a conference room, when a meeting is finished, people leave the conference room, infrared detection devices on the illuminating lamps detect that no people exist in the conference room, and all illuminating lamps in the conference room are turned off after one minute. The turn-off rate of the lighting lamps in the conference room is 100%, and the control module 3 generates a control instruction according to the turn-off rate to control the output of the air conditioner, specifically, the air conditioner can be turned off or the air conditioner can enter energy-saving control.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed.
