Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling a multi-split air conditioner, which may include the steps of:
s1, acquiring the identification of the target indoor unit and the operation information corresponding to each target indoor unit, wherein the target indoor unit is an indoor unit in an operation state;
s2, calculating the capacity requirement value of the indoor unit in the multi-split air conditioner according to the operation information corresponding to each target indoor unit;
s3, determining the working frequency required by the compressor in the outdoor unit when all target indoor units are driven to operate according to the corresponding operation information according to the capacity requirement value;
s4, determining whether the multi-split air conditioner needs energy-saving adjustment or not according to the working frequency, and executing the step S5 if the multi-split air conditioner needs energy-saving adjustment;
s5, adjusting the operation information of the target indoor unit according to a set rule;
and S6, controlling the target indoor unit corresponding to the adjusted operation information to operate according to the adjusted operation information.
In the embodiment of the invention, whether the multi-split air conditioner needs energy-saving regulation or not is determined according to the working frequency of the compressor, if the multi-split air conditioner needs energy-saving regulation, the operation information of the target indoor unit is regulated according to a set rule, and the target indoor unit corresponding to the regulated operation information is controlled to operate according to the regulated operation information. The operation information of the target indoor unit is adjusted according to the set rule, and the target indoor unit corresponding to the adjusted operation information is controlled to operate according to the adjusted operation information, so that the energy-saving adjustment of the multi-split air conditioner can be realized.
In an embodiment of the present invention, determining whether the multi-split air conditioner needs to perform energy saving adjustment according to the current operating frequency of the compressor specifically includes: when the current working frequency is greater than the set frequency, determining that energy-saving adjustment is needed, otherwise, determining that energy-saving adjustment is not needed; wherein the set frequency is positively correlated with the number of the target indoor units.
In this embodiment, the set frequency is positively correlated with the number of target indoor units, may be linearly or non-linearly, and is not particularly limited herein. In addition, the set frequency is not only related to the number of target indoor units, but also related to the temperature difference of the set temperature of different target indoor units. When the number of the target indoor units and the temperature difference of the set temperatures of different target indoor units are taken into consideration as the setting factor of the set frequency, the set frequency can be set more accurately, and therefore the adjustment of the multi-split air conditioner to the energy-saving state is facilitated.
Of course, before step S4, a control command for sending the energy saving operation to the outdoor unit by means of human control may be included.
In an embodiment of the invention, when it is determined that the multi-split air conditioner needs energy-saving adjustment according to the current working frequency of the compressor, the operation information of the target indoor unit can be adjusted according to the set rule, and the target indoor unit corresponding to the adjusted operation information is controlled to operate according to the adjusted operation information, so that the energy-saving adjustment of the multi-split air conditioner can be realized. And otherwise, when the multi-split air conditioner is determined not to need energy-saving adjustment, the multi-split air conditioner is proved to be in an energy-saving state at present.
It should be noted that the energy saving regulation does not necessarily represent the ability of the multi-split air conditioner to operate in an energy saving state after the energy saving regulation; however, when the energy-saving regulation is not needed, the multi-split air conditioner is always in the energy-saving state, and for the specific explanation, refer to the following.
In an embodiment of the present invention, in the method for adjusting the operation information of the target indoor unit according to the set rule shown in fig. 1, the operation information of the target indoor unit can be adjusted at least in one of the following manners. Specifically, the method may comprise the steps of:
when each piece of operation information corresponds to a heating mode, the following steps are executed:
s51, adjusting the maximum set temperature in each current operation information to a set temperature adjacent to the maximum set temperature, executing steps S2-S4, and if it is still determined in step S4 that energy saving adjustment is necessary, continuing to execute step S51 until it is determined in step S4 that energy saving adjustment is not necessary, or until the set temperatures in each current operation information are equal.
In this embodiment, when the target indoor unit operates in the heating mode, the setting rule is to adjust the highest set temperature in each current operation information to the set temperature adjacent to the highest set temperature, so that the operating frequency of the compressor can be reduced, and thus the energy-saving adjustment of the multi-split air conditioner can be realized.
In an embodiment of the present invention, in the method for adjusting the operation information of the target indoor unit according to the set rule shown in fig. 1, the operation information of the target indoor unit can be adjusted at least in one of the following manners. Specifically, the method may comprise the steps of:
when each piece of operation information corresponds to a refrigeration mode, the following steps are executed:
s52, adjusting the lowest set temperature in each current operation information to a set temperature adjacent to the lowest set temperature, executing steps S2-S4, and if it is still determined in step S4 that energy saving adjustment is necessary, continuing to execute step S52 until it is determined in step S4 that energy saving adjustment is unnecessary, or until the set temperatures in each current operation information are equal.
In this embodiment, when the target indoor unit operates in the cooling mode, the setting rule is to adjust the lowest set temperature in each current operation information to the set temperature adjacent to the lowest set temperature, so that the operating frequency of the compressor can be reduced, and thus the energy-saving adjustment of the multi-split air conditioner can be realized.
As shown in fig. 2, another embodiment of the present invention further provides a method for controlling a multi-split air conditioner.
The control method comprises the following steps:
101. acquiring an identifier of a target indoor unit and operation information corresponding to each target indoor unit;
in this embodiment, the identifier of the target indoor unit is a unique identifier of the indoor unit, and may be, for example, an identity Identification (ID) of the target indoor unit, so that not only the indoor unit in the running state but also the number of the indoor units in the running state may be determined by obtaining the identifier of the target indoor unit. In this embodiment, the operation information corresponding to each target indoor unit may include at least one or more of an operation mode (such as a cooling mode, a heating mode, etc.), a set temperature, and a current ambient temperature.
102. Calculating the capacity demand value of the indoor unit in the multi-split air conditioner according to the operation information corresponding to each target indoor unit;
the working frequency of the outdoor unit is related to the capacity demand value of the indoor unit, and the larger the capacity demand value is, the larger the working frequency required by the outdoor unit is, so that the capacity demand value of the indoor unit needs to be calculated in order to know the working frequency required by the outdoor unit. In this embodiment, calculating the capacity requirement value of the indoor unit in the multi-split air conditioner according to the operation information corresponding to each target indoor unit specifically includes: and calculating the capacity requirement value of the indoor unit in the multi-split air conditioner according to the operation mode (such as a cooling mode, a heating mode and the like) of each target indoor unit and the number of the target indoor units. The operation mode of the indoor unit can be obtained by an external control device, and the external control device can be a wire controller or a remote controller and the like; and the number of the target indoor units is determined by the acquired identification of the target indoor units.
In order to ensure that the capacity demand value of the indoor unit is calculated more accurately, the capacity demand value of the indoor unit can be further calculated according to the temperature difference between the set temperature of the target indoor unit and the current indoor environment temperature. The current indoor ambient temperature can be obtained by a temperature sensor arranged in the indoor unit, and the set temperature can be obtained by an external control device, wherein the external control device can be a wire controller or a remote controller and the like.
In order to further ensure that the capacity demand value of the indoor unit is calculated more accurately, the capacity demand value of the indoor unit can be further calculated according to the current outdoor environment temperature, wherein the current outdoor environment temperature can be obtained by a temperature sensor arranged in the outdoor unit.
103. Calculating the capacity demand value of the indoor unit in the multi-split air conditioner according to the operation information corresponding to each target indoor unit;
in this embodiment, according to the calculated capacity requirement value, the operating frequency required by the compressor in the outdoor unit when all the target indoor units are driven to operate according to the corresponding operation information is determined. It should be noted that, when the indoor unit starts to operate, the temperature difference between the set temperature of the indoor unit and the current indoor environment temperature is relatively large, and as the operating time of the multi-split air conditioner is prolonged, the temperature difference between the set temperature of the indoor unit and the current indoor environment temperature is gradually reduced, and the operating frequency of the compressor tends to be stable gradually.
104. Judging whether the current working frequency is greater than a set frequency; if yes, go to step 1051 or 1052; if not, go to step 1053;
on the one hand, the set frequency is positively correlated with the number of target indoor units. For example, when the number of target indoor units is one, the set frequency may be 30 Hz; when the number of the target indoor units is two, the set frequency can be 60 Hz; when the number of target indoor units is three, the set frequency may be 80 Hz. Generally, the operation frequency of the compressor is 80-100Hz, which can be considered as a high frequency state, the operation frequency is 60-80Hz, which can be considered as a medium frequency state, and the operation frequency is 30-60Hz, which can be considered as a low frequency state.
On the other hand, the set frequency is not only in positive correlation with the number of target indoor units, but also in correlation with the temperature difference between the set temperatures of different target indoor units. For example, taking the indoor unit in the heating mode as an example, there are three target indoor units, namely a first indoor unit, a second indoor unit and a third indoor unit, wherein the set temperature of the first indoor unit is 20 ℃, the set temperature of the second indoor unit is 25 ℃ and the set temperature of the third indoor unit is 30 ℃, and the total temperature difference of the three target indoor units is 10 ℃ (the total temperature difference can be considered as the difference between the highest set temperature and the lowest set temperature), the following rules are provided: when the total temperature difference of the three target indoor units is 10 ℃ or more, the set frequency of the compressor can be set to be 85 Hz; when the total temperature difference phase difference of the three target indoor units is 5-10 ℃, the set frequency of the compressor can be set to be 80 Hz; when the total temperature difference of the three target indoor units is 0-5 ℃, the set frequency of the compressor can be set to be 75 Hz. 1051. When each piece of operation information corresponds to a heating mode, adjusting the highest set temperature in each piece of current operation information to a set temperature adjacent to the highest set temperature, and executing step 102 and step 104, if it is still determined in step 104 that energy-saving adjustment is needed, continuing to execute step 1051 until it is determined in step 104 that energy-saving adjustment is not needed, or until the set temperatures in each piece of current operation information are equal;
for example, there are three target indoor units, i.e., a first indoor unit, a second indoor unit, and a third indoor unit, wherein the set temperature of the first indoor unit is 20 ℃, the set temperature of the second indoor unit is 25 ℃, the set temperature of the third indoor unit is 30 ℃, the total temperature difference of the three target indoor units is 10 ℃, and the set frequency of the compressor can be set to be 85 Hz. Assuming that the current operating frequency of the compressor is 90Hz at this time, the steps are executed according to step S51, the set temperature of the first indoor unit is 20 ℃, the set temperature of the second indoor unit is 25 ℃ and the set temperature of the third indoor unit is 25 ℃, the total temperature difference of the three target indoor units is 5 ℃, and at this time, the current operating frequency of the compressor is calculated to be 85 Hz. At this time, the execution is continued according to step S51, the set temperature of the first indoor unit after the execution is 20 ℃, the set temperature of the second indoor unit is 20 ℃, and the set temperature of the third indoor unit is 20 ℃, at this time, the current operating frequency of the compressor is calculated to be 80Hz, and the value is less than the set frequency of the compressor 85Hz before the adjustment is started, so that the multi-split air conditioner is in the energy-saving state operation at this time. Meanwhile, the set temperatures of the three target indoor units are also equal. Of course, if the multi-split air conditioner is in the energy-saving state after the first adjustment, and the set temperatures of the three target indoor units are not all equal, the set temperature of the target indoor unit does not need to be adjusted.
1052. When each piece of operation information corresponds to the refrigeration mode, adjusting the lowest set temperature in each piece of current operation information to the set temperature adjacent to the lowest set temperature, and executing step 102 and step 104, if it is still determined in step 104 that energy-saving adjustment is needed, continuing to execute step 1051 until it is determined in step 104 that energy-saving adjustment is not needed, or until the set temperatures in each piece of current operation information are equal;
for example, there are three target indoor units, i.e., a first indoor unit, a second indoor unit, and a third indoor unit, wherein the set temperature of the first indoor unit is 16 ℃, the set temperature of the second indoor unit is 20 ℃, the set temperature of the third indoor unit is 25 ℃, the total temperature difference of the three target indoor units is 9 ℃, and the set frequency of the compressor can be set to 80 Hz. Assuming that the current operating frequency of the compressor is 85Hz at this time, the steps are executed according to step S51, the set temperature of the first indoor unit is 20 ℃, the set temperature of the second indoor unit is 20 ℃ and the set temperature of the third indoor unit is 25 ℃, the total temperature difference of the three target indoor units is 5 ℃, and at this time, the current operating frequency of the compressor is calculated to obtain 80 Hz. At this time, the execution is continued according to step S51, the set temperature of the first indoor unit after the execution is 25 ℃, the set temperature of the second indoor unit is 25 ℃, and the set temperature of the third indoor unit is 25 ℃, at this time, the current operating frequency of the compressor is calculated to be 75Hz, and the value is less than the set frequency of the compressor 80Hz before the adjustment is started, so that the multi-split air conditioner is in the energy-saving state operation at this time. Meanwhile, the set temperatures of the three target indoor units are also equal. Of course, if the multi-split air conditioner is in the energy-saving state after the first adjustment, and the set temperatures of the three target indoor units are not all equal, the set temperature of the target indoor unit does not need to be adjusted.
However, there is a counter example after the energy saving adjustment process in the above two modes (i.e., the heating mode and the cooling mode), that is, even if the set temperatures of all the target indoor units are adjusted to be the same, the multi-split air conditioner may not be operated in the energy saving state at this time. However, if the target indoor unit is adjusted in temperature setting, it is considered to be energy saving adjustment, that is, the operating frequency of the compressor after energy saving adjustment is necessarily reduced. That is, when the set temperatures of all the target indoor units are adjusted to be consistent, the operating frequency of the compressor is necessarily lower than the operating frequency of the compressor under the condition that at least two different set temperatures of the target indoor units exist, that is, the energy-saving adjustment of the multi-split air conditioner can be realized by adjusting the set temperatures of the target indoor units.
1053. Energy-saving adjustment is not needed;
106. and controlling the target indoor unit corresponding to the adjusted operation information to operate according to the adjusted operation information.
