Detailed Description
The embodiment of the invention provides an air conditioner control method, an air conditioner system and an air conditioner, and solves the technical problem that the linkage of air conditioner partition and overall machine control in the prior art is poor.
In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As shown in fig. 1, the air conditioner of this embodiment includes an indoor unit, a line controller, a plurality of temperature controllers, an outdoor unit connected to the indoor unit, and a plurality of temperature control pipelines connected to the indoor unit; the plurality of temperature controllers are in communication connection with the line controller, the line controller is in communication connection with the indoor unit, and the plurality of temperature control pipelines and the plurality of temperature controllers are correspondingly arranged in the plurality of subareas one by one; each temperature control pipeline is provided with an air valve.
As shown in fig. 2, the air conditioner control method of the present embodiment includes:
step S1, acquiring the temperature difference between the environment temperature of each subarea and the set temperature of the subarea;
and step S2, controlling the temperature control parameters of the indoor unit and/or the outdoor unit according to the temperature difference of the plurality of subareas.
In step S1, the set temperature of each zone is the temperature set by the user in the temperature controller corresponding to the zone. The temperature difference is a relative value, which can be understood as: in the refrigeration mode, the default temperature set by a user is lower than the ambient temperature, and the temperature difference is the value obtained by subtracting the set temperature from the ambient temperature; in the heating mode, the default temperature set by the user is higher than the ambient temperature, and the temperature difference is the value obtained by subtracting the ambient temperature from the set temperature.
In step S2, the temperature control parameter is a parameter that affects the temperature control effect of the air conditioner, and the temperature control parameter may be any one or more of the air volume of the indoor unit, the compressor frequency of the outdoor unit, and the opening degree of the expansion valve, and in this embodiment, the temperature control parameter includes one or two of the air volume of the indoor unit and the compressor frequency of the outdoor unit. Step S2 may be to control the temperature control parameters of the indoor unit individually according to the temperature differences of the multiple zones, where the temperature control parameters may include the air volume of the indoor unit; the temperature control parameters of the outdoor unit can be independently controlled according to the temperature difference of the plurality of subareas, and the temperature control parameters can comprise the frequency of a compressor of the outdoor unit; and simultaneously controlling temperature control parameters of the indoor unit and the outdoor unit according to the temperature difference of the plurality of subareas, wherein the temperature control parameters comprise the air volume of the indoor unit and the compressor frequency of the outdoor unit.
As can be seen from the above, in the present embodiment, the temperature control parameters of the indoor unit and/or the outdoor unit are controlled according to the temperature differences of the plurality of zones, which is equivalent to controlling the operation of the whole unit through the temperature differences of the plurality of zones, thereby realizing the linkage of the control of the zones and the whole unit, and improving the temperature control effect of the air conditioner.
In step S2, the temperature control parameters of the indoor unit and/or the outdoor unit may be controlled according to the temperature differences of the multiple partitions in multiple ways, for example, the temperature control parameters of the indoor unit and/or the outdoor unit may be controlled according to the weighted sum or the sum of squares of the temperature differences of the multiple partitions. The present embodiment provides another simpler way, that is, step S2 includes:
and controlling the temperature control parameters of the indoor unit and/or the outdoor unit according to the sum of the temperature differences of the plurality of subareas.
The sum of the temperature differences of the multiple zones represents the total demand of the multiple zones for cooling or heating, and it can be understood that the greater the total demand of the multiple zones for cooling or heating, the greater the temperature control parameter should be; the smaller the total demand of the plurality of partitions for cooling or heating, the smaller the temperature control parameter should be, so that the better the temperature control effect of the air conditioner is. In view of the above principle, the present embodiment provides two ideas to control the temperature control parameters of the indoor unit and/or the outdoor unit according to the sum of the temperature differences of the plurality of zones. The temperature control parameters including the air volume of the indoor unit and the compressor frequency of the outdoor unit will be described as an example.
In a first concept, controlling temperature control parameters of an indoor unit and/or an outdoor unit includes: the control temperature control parameter is positively correlated with the sum of the temperature differences of the plurality of zones. Specifically, the temperature control parameter is continuously changed according to the sum of the temperature differences of the plurality of zones, and the larger the sum of the temperature differences of the plurality of zones is, the larger the air volume of the indoor unit and the frequency of the compressor of the outdoor unit are. However, the requirement on the control function of the air conditioner is high and unnecessary when the temperature control parameter continuously changes along with the sum of the temperature differences of the plurality of zones, and in order to reduce the difficulty of controlling the temperature control parameter by the air conditioner, the second idea is preferably selected in the embodiment.
In a second idea, controlling temperature control parameters of the indoor unit and/or the outdoor unit according to a sum of temperature differences of the multiple zones includes: determining a temperature interval in which the sum of the temperature differences of the plurality of zones is located; the control temperature parameter is a target parameter corresponding to a temperature interval in which the sum is located, and the larger the average temperature value in the temperature interval is, the larger the corresponding target parameter is. The temperature control parameters comprise the air volume of the indoor unit and the compressor frequency of the outdoor unit, and the target parameters comprise the target air volume and the target frequency.
Specifically, a plurality of temperature intervals and target parameters corresponding to each temperature interval may be preset, for example, if the total of the temperature differences of the plurality of temperature intervals is t, 0< t <3 corresponds to a target air volume of 1 (representing a low air volume), a target frequency of 1 (representing a low frequency), 3< t <6 corresponds to a target air volume of 2 (representing a medium air volume), a target frequency of 2 (representing a medium frequency), 6 < t <9 corresponds to a target air volume of 3 (representing a next-high air volume), a target frequency of 3 (representing a second-high frequency), 9 < t <12 corresponds to a target air volume of 4 (representing a high air volume), a target frequency of 4 (representing a high frequency), 12 < t corresponds to a target air volume of 5 (representing a strong air volume), and a target frequency of 5 (representing an ultrahigh frequency) may be set. When the temperature interval in which the sum of the temperature differences of the plurality of subareas is located is 3-6, controlling the air volume of the indoor unit to be medium air volume and the frequency of the compressor of the outdoor unit to be medium frequency; and when the temperature interval in which the sum of the temperature differences of the plurality of subareas is located is 9-12, controlling the air volume of the indoor unit to be high and the frequency of the compressor of the outdoor unit to be high frequency. Of course, other temperature interval classifications are also possible.
In the foregoing, mainly for the linkage strategy of the partition and the overall control, the embodiment further provides a control strategy of a single partition, that is, after step S1, the air conditioner control method further includes: and controlling the opening degree of an air valve of the temperature control pipeline corresponding to each subarea according to the temperature difference corresponding to each subarea.
The temperature difference of each partition represents the requirement of each partition for cooling or heating, and it can be understood that the larger the requirement of a partition for cooling or heating is, the larger the opening degree of the air valve corresponding to the partition should be; the smaller the requirement of a certain subarea for cooling or heating, the smaller the opening degree of the air valve corresponding to the subarea is, so that the better the temperature control effect of the subarea is. Based on the principle, the method is similar to the linkage of the subareas and the whole machine, and the embodiment also provides two ideas for controlling the opening degree of the air valve of the temperature control pipeline corresponding to the subarea according to the temperature difference corresponding to the subareas.
In the first kind of thinking, the blast gate aperture of the temperature control pipeline that this subregion corresponds of control includes: and controlling the positive correlation between the opening degree of the air valve of the temperature control pipeline corresponding to the partition and the temperature difference. And will not be described in detail herein.
In the second kind of thinking, according to the temperature difference that every subregion corresponds, the blast gate aperture of the temperature control pipeline that this subregion corresponds includes: determining a temperature interval in which the temperature difference is located; the opening degree of the control air valve is a target opening degree corresponding to a temperature interval where the temperature difference is located, and the larger the average temperature value in the temperature interval is, the larger the corresponding target opening degree is.
Specifically, a plurality of temperature intervals and a target opening degree corresponding to each temperature interval may be preset, and if the temperature difference of a certain partition is T, a target opening degree corresponding to 0< T <1 may be set to 30 °, a target opening degree corresponding to 1< T < 2 may be set to 45 °, a target opening degree corresponding to 2< T <3 may be set to 60 °, a target opening degree corresponding to 3< T < 4 may be set to 75 °, and a target opening degree corresponding to 4< T may be set to 90 °. Thus, when the temperature interval of the temperature difference of a certain subarea is 1-2, the opening degree of the air valve of the subarea is controlled to be 45 degrees; and when the temperature interval of the temperature difference of a certain subarea is 2-3, controlling the opening degree of the air valve of the subarea to be 60 degrees. Of course, other temperature interval classifications are also possible.
In addition, the embodiment also provides an air conditioning system, which comprises an indoor unit, a wire controller, a plurality of temperature controllers, an outdoor unit connected with the indoor unit, and a plurality of temperature control pipelines connected with the indoor unit; the plurality of temperature controllers are in communication connection with the wire controllers, the wire controllers are in communication connection with the indoor unit, the plurality of temperature control pipelines are correspondingly arranged in a plurality of subareas one by one, and the plurality of temperature controllers are correspondingly arranged in the plurality of subareas one by one; the temperature controller is used for detecting the ambient temperature of the corresponding subarea; the wire controller is used for acquiring the temperature difference between the environment temperature of each subarea and the set temperature of the subarea; and controlling the temperature control parameters of the indoor unit and/or the outdoor unit according to the temperature difference of the plurality of subareas.
In the air conditioning system, the set temperature of a partition is the temperature set by a user in the temperature controller corresponding to the partition. The temperature difference is a relative value, which can be understood as: in the refrigeration mode, the default temperature set by a user is lower than the ambient temperature, and the temperature difference is the value obtained by subtracting the set temperature from the ambient temperature; in the heating mode, the default temperature set by the user is higher than the ambient temperature, and the temperature difference is the value obtained by subtracting the ambient temperature from the set temperature.
The temperature control parameter is a parameter that affects the temperature control effect of the air conditioner, and may be any one or more of the air volume of the indoor unit, the compressor frequency of the outdoor unit, the opening degree of the expansion valve, and the like. The wire controller can independently control the temperature control parameters of the indoor unit according to the temperature difference of the plurality of subareas, and the temperature control parameters can comprise the air volume of the indoor unit; the temperature control parameters of the outdoor unit can be independently controlled according to the temperature difference of the plurality of subareas, and the temperature control parameters can comprise the frequency of a compressor of the outdoor unit; and simultaneously controlling temperature control parameters of the indoor unit and the outdoor unit according to the temperature difference of the plurality of subareas, wherein the temperature control parameters comprise the air volume of the indoor unit and the compressor frequency of the outdoor unit.
As can be seen from the above, the air conditioning system of this embodiment controls the temperature control parameters of the indoor unit and/or the outdoor unit according to the temperature differences of the plurality of zones, which is equivalent to controlling the operation of the whole air conditioning system through the temperature differences of the plurality of zones, thereby realizing the linkage of the control of the zones and the whole air conditioning system and improving the temperature control effect of the air conditioning system.
The line controller can control the temperature control parameters of the indoor unit and/or the outdoor unit according to the temperature differences of the multiple zones in multiple ways, for example, the temperature control parameters of the indoor unit and/or the outdoor unit can be controlled according to the weighted sum or the sum of squares of the temperature differences of the multiple zones. This embodiment provides another simpler way, namely the drive-by-wire is also used to:
and controlling the temperature control parameters of the indoor unit and/or the outdoor unit according to the sum of the temperature differences of the plurality of subareas.
The sum of the temperature differences of the multiple zones represents the total demand of the multiple zones for cooling or heating, and it can be understood that the larger the total demand of the multiple zones for cooling or heating, the larger the temperature control parameter should be; the smaller the total demand of the plurality of partitions for cooling or heating, the smaller the temperature control parameter should be, so that the better the temperature control effect of the air conditioner is. In view of the above principle, the present embodiment provides two ideas to control the temperature control parameters of the indoor unit and/or the outdoor unit according to the sum of the temperature differences of the plurality of zones. The temperature control parameters including the air volume of the indoor unit and the compressor frequency of the outdoor unit will be described as an example.
In a first concept, the wire controller controls temperature control parameters of the indoor unit and/or the outdoor unit, including: the control temperature control parameter is positively correlated with the sum of the temperature differences of the plurality of zones. Specifically, the temperature control parameter is continuously changed according to the sum of the temperature differences of the plurality of zones, and the larger the sum of the temperature differences of the plurality of zones is, the larger the air volume of the indoor unit and the frequency of the compressor of the outdoor unit are. However, the requirement on the control function of the air conditioner is high and unnecessary when the temperature control parameter continuously changes along with the sum of the temperature differences of the plurality of zones, and in order to reduce the difficulty of controlling the temperature control parameter by the air conditioner, the second idea is preferably selected in the embodiment.
In a second concept, the controlling device controls the temperature controlling parameters of the indoor unit and/or the outdoor unit according to the sum of the temperature differences of the plurality of partitions, including: determining a temperature interval in which the sum of the temperature differences of the plurality of zones is located; the control temperature parameter is a target parameter corresponding to a temperature interval in which the sum is located, and the larger the average temperature value in the temperature interval is, the larger the corresponding target parameter is. The temperature control parameters comprise the air volume of the indoor unit and the compressor frequency of the outdoor unit, and the target parameters comprise the target air volume and the target frequency.
Specifically, a plurality of temperature intervals and target parameters corresponding to each temperature interval may be preset, for example, if the total of the temperature differences of the plurality of temperature intervals is t, 0< t <3 corresponds to a target air volume of 1 (representing a low air volume), a target frequency of 1 (representing a low frequency), 3< t <6 corresponds to a target air volume of 2 (representing a medium air volume), a target frequency of 2 (representing a medium frequency), 6 < t <9 corresponds to a target air volume of 3 (representing a next-high air volume), a target frequency of 3 (representing a second-high frequency), 9 < t <12 corresponds to a target air volume of 4 (representing a high air volume), a target frequency of 4 (representing a high frequency), 12 < t corresponds to a target air volume of 5 (representing a strong air volume), and a target frequency of 5 (representing an ultrahigh frequency) may be set. When the temperature interval in which the sum of the temperature differences of the plurality of subareas is located is 3-6, controlling the air volume of the indoor unit to be medium air volume and the frequency of the compressor of the outdoor unit to be medium frequency; and when the temperature interval where the sum of the temperature differences of the plurality of subareas is 9-12, controlling the air volume of the indoor unit to be high and the frequency of the compressor of the outdoor unit to be high frequency. Of course, other temperature interval classifications are also possible.
The air conditioning system of the present embodiment further provides a control strategy for a single partition, that is, after the line controller obtains a temperature difference between an ambient temperature of each partition and a set temperature of the partition, the line controller is further configured to: and controlling the opening degree of an air valve of the temperature control pipeline corresponding to each subarea according to the temperature difference corresponding to each subarea.
The temperature difference of each partition represents the requirement of each partition for cooling or heating, and it can be understood that the larger the requirement of a partition for cooling or heating is, the larger the opening degree of the air valve corresponding to the partition should be; the smaller the requirement of a certain subarea for cooling or heating, the smaller the opening degree of the air valve corresponding to the subarea is, so that the better the temperature control effect of the subarea is. Based on the principle, the method is similar to the linkage of the subareas and the whole machine, and the embodiment also provides two ideas for controlling the opening degree of the air valve of the temperature control pipeline corresponding to the subarea according to the temperature difference corresponding to the subareas.
In the first kind of thinking, the blast gate aperture of the temperature control pipeline that this subregion corresponds is controlled, includes: and controlling the opening degree of an air valve of the temperature control pipeline corresponding to the partition to be positively correlated with the temperature difference. And will not be described in detail herein.
In the second kind of thinking, according to the temperature difference that every subregion corresponds, the blast gate aperture of the temperature control pipeline that this subregion corresponds is controlled, includes: determining a temperature interval in which the temperature difference is located; the opening degree of the control air valve is a target opening degree corresponding to a temperature interval in which the temperature difference is located, and the larger the average temperature value in the temperature interval is, the larger the corresponding target opening degree is.
Specifically, a plurality of temperature intervals and a target opening degree corresponding to each temperature interval may be preset, and if a temperature difference of a certain partition is set to T, a target opening degree corresponding to 0< T <1 may be set to 30 °, a target opening degree corresponding to 1< T < 2 may be set to 45 °, a target opening degree corresponding to 2< T <3 may be set to 60 °, a target opening degree corresponding to 3< T < 4 may be set to 75 °, and a target opening degree corresponding to 4< T may be set to 90 °. Thus, when the temperature interval of the temperature difference of a certain subarea is 1-2, the opening degree of the air valve of the subarea is controlled to be 45 degrees; and when the temperature interval of the temperature difference of a certain subarea is 2-3, controlling the opening degree of the air valve of the subarea to be 60 degrees. Of course, other temperature interval classifications are also possible.
In addition, the embodiment also provides an air conditioner, which comprises a controller, wherein the controller is used for controlling the operation of the air conditioner according to any one of the air conditioner control methods. The air conditioner of the embodiment controls the temperature control parameters of the indoor unit and/or the outdoor unit according to the temperature difference of the plurality of subareas, which is equivalent to controlling the operation of the whole machine through the temperature difference of the plurality of subareas, thereby realizing the linkage of subareas and the control of the whole machine and improving the temperature control effect of the air conditioner.
