Detailed Description
Technical solutions in some embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings, however, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by one of ordinary skill in the art based on the embodiments provided by the present disclosure are within the scope of the present disclosure.
As described above, the heat load conditions of each room are obviously different due to obvious differences of the house structure, the size, the direction, the resident personnel and the like, and when the air conditioner is actually installed, if the air conditioner is subjected to temperature adjustment according to the fixed temperature compensation set by a factory, the air conditioner cannot be matched with the temperature change caused by the difference of the actual rooms of users.
To this end, some embodiments of the present disclosure provide a control method of an air conditioner, as shown in fig. 1, including steps 11 to 19.
And 11, acquiring a user set temperature, a first indoor environment temperature and a first temperature compensation value.
In some embodiments, the operation of obtaining the first temperature compensation value includes determining the first temperature compensation value based on a room load and/or a user attribute in which the air conditioner is located.
For example, when the air conditioner is actually installed, an installer of the air conditioner may determine a room load according to the size of the room volume of the user, and then obtain a recommended first temperature compensation value according to the room load and the user attribute after the air conditioner is installed. After the first temperature compensation value is obtained, an air conditioner installer sets the first temperature compensation value of the air conditioner through a remote controller of the air conditioner so as to meet the room temperature control requirement after the air conditioner is installed, and therefore the requirement of user comfort can be better met.
When the air conditioner is installed, an installer can measure the length, width and height of an installation room, calculate the room volume according to the length, width and height, and set a first temperature compensation value according to the room volumes recommended by different cooling capacity sections in the specification of the air conditioner.
For example, the recommended room volume is about 36m 3 to 45m 3 (inclusive) when the rated cooling nominal of the air conditioner is 3500W. If the calculated actual room volume is less than 36m 3, or the volume is moderate (i.e., room volume is about 36m 3 to 45m 3) but the room is closed without a window, the load is considered to be small. If the calculated actual room volume is greater than 45m 3, or the volume is moderate but the room is multi-window or the volume is moderate but in the western sun direction, the load is considered to be larger.
Or for example, the recommended room volume is about 24m 3-30m 3 (inclusive) when the rated cooling of the air conditioner is nominally 2600W. If the calculated actual volume of the room is smaller than 24m 3 or the volume is moderate but the room is closed and has no window, the load is considered to be smaller. If the calculated actual volume of the room is larger than 45m 3, or the volume is moderate but the room is multi-window or the volume is moderate but the room is located in the western sun direction, the load is considered to be larger. Therefore, the recommended room volumes of the air conditioners with different refrigerating capacity models can be described in detail in the specification, and the installer can conveniently confirm the room load condition according to the actual condition.
User attributes include cold afraid, neutral, and heat afraid. Cold-feeling people refer to people who feel cold more easily at the same temperature, such as the elderly or children. The people afraid of heat refer to people who are more likely to feel heat at the same temperature, such as teenagers. Neutral population refers to a population that feels a suitable temperature at the same temperature, such as a middle aged population.
Illustratively, in the cooling mode, the first temperature compensation value is in the range of-2 ℃ to 2 ℃. For example, the first temperature compensation value in the cooling mode may be-2 ℃, -1.5 ℃, -1 ℃, -0.5 ℃,1 ℃,1.5 ℃,2 ℃, etc.
In the heating mode, the value range of the first temperature compensation value is 0 ℃ to 5 ℃. For example, the first temperature compensation value in the heating mode may be 0 ℃,0.5 ℃,1 ℃,1.5 ℃,2 ℃,2.5 ℃,3 ℃,3.5 ℃,4 ℃,4.5 ℃,5 ℃, or the like.
In some embodiments, the control method of the air conditioner further includes, before performing the operation of obtaining the first temperature compensation value, establishing a first temperature compensation table based on a room load and/or a user attribute in which the air conditioner is located. On this basis, the operation of obtaining the first temperature compensation value includes: and searching the first temperature compensation table, and determining the first temperature compensation value according to the room load and/or the user attribute of the air conditioner.
For example, the first temperature compensation table includes tables 1, 2 and 3 described below.
Table 1 comparison table of room load and first temperature compensation value (cooling mode and heating mode)
TABLE 2 comparison of user Properties with first temperature Compensation values (refrigeration and heating modes)
For example, as shown in table 1, after the air conditioner installer determines the room load according to the structure, the volume, the direction, etc. of the user room, the air conditioner installer searches the temperature compensation table established based on the room load of the room in which the air conditioner is located and the operation mode of the air conditioner for the first temperature compensation value corresponding to the air conditioner in the cooling mode or the heating mode.
For another example, as shown in table 2, when the air conditioner installer determines the main user attribute of the installation room through inquiry, the first temperature compensation value of the air conditioner in the cooling mode or the heating mode is searched for in the temperature compensation table established based on the user attribute and the operation mode of the air conditioner.
TABLE 3 user Properties, comparison of room load with first temperature Compensation values (Cooling and heating modes)
For another example, as shown in table 3, after the air conditioner installer determines the main user attribute of the installation room through inquiry, the first temperature compensation value of the air conditioner corresponding to the cooling mode or the heating mode is searched in the temperature compensation table established based on the room load and the user attribute of the room where the air conditioner is located.
In some embodiments, in step 11, the first indoor ambient temperature is obtained by a temperature sensor. The temperature sensor may be a temperature sensor integrated in the air conditioner, or may be a temperature sensor provided outside the air conditioner but capable of communicating with the air conditioner to transmit data or signals.
And step 12, determining a first indoor environment calculation temperature and a first temperature difference according to the user set temperature, the first indoor environment temperature and the first temperature compensation value.
For example, when the air conditioner operates in the cooling mode, the first indoor environment calculation temperature and the first temperature difference are determined according to the following formula:
T CE1＝T E1-T C1,T D1＝T CE1-T S。
When the air conditioner operates in a heating mode, a first indoor environment calculation temperature and a first temperature difference are determined according to the following formula:
T CE1＝T E1+T C1,T D1＝T S-T CE1。
In the above two formulas, T CE1 is the first indoor environment calculated temperature, T E1 is the first indoor environment temperature, T C1 is the first temperature compensation value, T D1 is the first temperature difference, and T S is the user set temperature.
The detected first indoor environment temperature can be effectively corrected through the first temperature compensation value, the temperature difference between the first indoor environment temperature and the indoor actual temperature is reduced, so that the first indoor environment calculated temperature is close to the indoor actual temperature, the temperature difference between the indoor actual temperature and the user set temperature can be more accurately calculated, the running state of the air conditioner is conveniently adjusted according to the first temperature difference, the indoor temperature difference is reduced, the uniformity of the indoor temperature is guaranteed, and the comfort level of the user is improved.
And step 13, judging whether the first temperature difference is smaller than or equal to a preset temperature difference threshold value. If so, step 14 is performed. If not, step 18 is performed.
When the first temperature difference is smaller than or equal to the preset temperature difference threshold value, the fact that the temperature difference between the indoor actual temperature and the user set temperature is smaller is indicated, and at the moment, if the operation frequency of the compressor is adjusted according to the first indoor environment calculated temperature and the first temperature difference, the indoor actual temperature can be reduced too much, and accurate control of the indoor actual temperature is not facilitated. Therefore, step 14 is also performed to obtain a more accurate basis for adjusting the air conditioner.
When the first temperature difference is larger than the preset temperature threshold, the temperature difference between the indoor actual temperature and the user set temperature is larger, and the output capacity of the air conditioner is adjusted by adjusting the operation frequency of the compressor, so that the indoor temperature can be quickly reduced or increased, and the user requirements can be better met.
Illustratively, when the air conditioner is operating in the cooling mode, the preset temperature threshold has a value ranging from 0 ℃ to 4 ℃. For example, the preset temperature threshold in the cooling mode may be 0 ℃,0.5 ℃,1 ℃,1.5 ℃,2 ℃,2.5 ℃,3 ℃,3.5 ℃,4 ℃, or the like.
When the air conditioner operates in a heating mode, the preset temperature threshold value ranges from 0 ℃ to 5 ℃. For example, the preset temperature threshold in the heating mode may be 0 ℃,0.5 ℃,1 ℃,1.5 ℃, -2 ℃,2.5 ℃,3 ℃,3.5 ℃,4 ℃,4.5 ℃, or 5 ℃, etc.
And 14, acquiring the gear of the indoor fan of the air conditioner and/or the opening angle of the air deflector.
And 15, determining a second temperature compensation value according to the gear of the indoor fan of the air conditioner and/or the opening angle of the air deflector.
Illustratively, the operation of determining the second temperature compensation value according to the gear of the indoor fan of the air conditioner and/or the opening angle of the air deflector includes: and determining a second temperature compensation value according to the gear of the indoor fan of the air conditioner.
In the refrigeration mode, according to the gear of the indoor fan of the air conditioner, the value range of the second temperature compensation value is determined to be-2 ℃ to 2 ℃. For example, the second temperature compensation value in the cooling mode may be-2 ℃, -1.5 ℃, -1 ℃, -0.5 ℃,1 ℃,1.5 ℃,2 ℃, etc.
In some embodiments, in the cooling mode, when the air damper of the air conditioner is a super strong air damper, the second temperature compensation value ranges from 0 ℃ to 1 ℃. For example, the second temperature compensation value may be 0.5 ℃ or 1 ℃ or the like.
In the refrigeration mode, when the air damper of the air conditioner is a high air damper or a medium air damper, the value range of the second temperature compensation value is-1 ℃ to 0 ℃. For example, the second temperature compensation value may be-1 ℃, -0.5 ℃ or 0 ℃ or the like.
In the refrigeration mode, when the air level of the air conditioner is low or mute, the value range of the second temperature compensation value is-2 ℃ to 0 ℃. For example, the second temperature compensation value may be-2 ℃, -1.5 ℃, -1 ℃ or-0.5 ℃ or the like.
When the air conditioner is operated in the cooling mode, the lower the gear of the air conditioner (i.e., the lower the rotational speed of the blower), the slower the rate at which the indoor temperature is lowered. The second temperature compensation value can be gradually adjusted from a negative value to a positive value along with the increase of the gear of the air conditioner, so that the corrected first indoor environment temperature is closer to the indoor actual temperature, and the comfort level of a user is ensured.
In some embodiments, the control method of the air conditioner further includes establishing a second temperature compensation table based on a gear of the indoor fan of the air conditioner before performing the operation of determining the second temperature compensation value according to the gear of the indoor fan of the air conditioner. On the basis, the operation of determining the second temperature compensation value according to the gear of the indoor fan of the air conditioner comprises the following steps: and searching the second temperature compensation table, and determining the second temperature compensation value according to the gear of the indoor fan of the air conditioner.
For example, the second temperature compensation value table determined according to the gear of the indoor fan of the air conditioner includes tables 4 and 5 described below.
As shown in table 4, from gear mute to gear super-strong, such as from gear mute to gear low wind, gear stroke, gear high wind, gear super-strong, the rotational speed of the fan may be gradually increased. The super strength can represent the maximum rotation speed of the fan, and the air conditioner has higher heat exchange efficiency and can quickly reduce the indoor temperature. The silence can indicate the minimum rotational speed of fan, and the air conditioner has less heat exchange efficiency this moment, can avoid indoor temperature too low.

High wind 0
Stroke 0
Low wind -0.5
Mute -0.5
In the heating mode, according to the gear of the indoor fan of the air conditioner, the value range of the second temperature compensation value is determined to be 0-3 ℃. For example, the second temperature compensation value in the heating mode may be 0 ℃,0.5 ℃,1 ℃,1.5 ℃,2 ℃,2.5 ℃,3 ℃, or the like.
In some embodiments, in the heating mode, when the air damper of the air conditioner is a super strong air damper, the second temperature compensation value ranges from 0 ℃ to 0.5 ℃. For example, the second temperature compensation value may be 0 ℃,0.3 ℃, 0.5 ℃, or the like.
In the heating mode, when the air damper of the air conditioner is a high air damper or a medium air damper, the value range of the second temperature compensation value is 0-1 ℃. For example, the second temperature compensation value may be 0.5 ℃,0.7 ℃,1 ℃, or the like.
In the heating mode, when the air damper of the air conditioner is a low air damper or a mute air damper, the value range of the second temperature compensation value is 0-2 ℃. For example, the second temperature compensation value may be 0.5 ℃,1 ℃,1.5 ℃,2 ℃, or the like.
When the air conditioner operates in the heating mode, the smaller the gear of the air conditioner is, the slower the rate of rise of the indoor temperature is, and the third temperature compensation value can be gradually adjusted to zero from a positive value along with the increase of the gear of the air conditioner, so that the corrected first indoor environment temperature is closer to the indoor actual temperature, and the comfort level of a user is ensured.
As shown in table 5, from gear mute to gear super power, the rotational speed of the fan may be gradually increased. The super strength can represent the maximum rotation speed of the fan, and the air conditioner has higher heat exchange efficiency and can quickly raise the indoor temperature. The silence can indicate the minimum rotational speed of fan, and the air conditioner has less heat exchange efficiency this moment, can avoid indoor temperature too high.

For example, the second temperature compensation value in the cooling mode may be-2 ℃, -1.5 ℃, -1 ℃, -0.5 ℃,1 ℃,1.5 ℃,2 ℃, etc.
In some embodiments, the control method of the air conditioner further includes creating a second temperature compensation table based on the opening angle of the air deflector of the air conditioner before performing the operation of determining the second temperature compensation value according to the opening angle of the air deflector of the air conditioner. On the basis, the operation of determining the second temperature compensation value according to the opening angle of the air deflector of the air conditioner comprises the following steps: and searching the second temperature compensation table, and determining the second temperature compensation value according to the opening angle of the air deflector of the air conditioner.

Angle 1 0.5
Angle 2 0.5

As shown in table 6, in the cooling mode, the second temperature compensation value may take different values according to the opening angle of the air deflector, so as to ensure that the indoor actual temperature is closer to the user set temperature. The opening angle of the deflector may be gradually reduced from angle 1 to angle 6. The angle 1 can be the maximum opening angle of the air deflector, and the air conditioner has higher heat exchange efficiency and can quickly reduce the indoor temperature. The angle 6 can be the minimum opening angle of the air deflector, and the air conditioner has smaller heat exchange efficiency at the moment, so that the indoor temperature can be prevented from being too low.
In the heating mode, according to the opening angle of the air deflector of the air conditioner, the value range of the second temperature compensation value is determined to be 0-2 ℃. For example, the second temperature compensation value in the heating mode may be 0 ℃,0.5 ℃,1 ℃,1.5 ℃,2 ℃, or the like.

As shown in table 7, the second temperature compensation value may take different values according to the opening angle of the air deflector, so as to ensure that the indoor actual temperature is closer to the user-set temperature. The opening angle of the deflector may be gradually reduced from angle 1 to angle 6. The angle 1 can be the maximum opening angle of the air deflector, and the air conditioner has higher heat exchange efficiency and can quickly raise the indoor temperature. The angle 6 can be the minimum opening angle of the air deflector, and the air conditioner has smaller heat exchange efficiency at the moment, so that the indoor temperature can be prevented from being too high.
