As shown in fig. 1, an embodiment of the present disclosure provides a method for determining a temperature compensation value, including:
s01, the air conditioner measures a temperature change rate in the room.
And S02, estimating the actual indoor area by the air conditioner according to the indoor temperature change rate.
And S03, the air conditioner determines a temperature compensation value according to the estimated actual area.
And S04, the air conditioner stores the temperature compensation value for being called when the air conditioner runs.
By adopting the method for determining the temperature compensation value provided by the embodiment of the disclosure, the indoor actual area can be estimated according to the indoor temperature change rate, the temperature compensation value is determined according to the indoor actual area, and the obtained temperature compensation value is stored for calling. The temperature compensation value obtained by calculation is adaptive to the actual application scene, the value is more accurate, the temperature compensation value does not need to be calculated in each calculation process, and the calculation process is simplified. Therefore, the process of determining the temperature compensation value is simplified, and the accuracy of the temperature compensation value is ensured.
As shown in fig. 2, optionally, the air conditioner measuring a temperature change rate in the room at S01 includes:
and S011, the air conditioner measures the temperature change amplitude delta T in the time interval T.
S012, calculating v by air conditionerPractice of＝ΔT/t。
In this way, the air conditioner can calculate the temperature change rate in actual operation.
Referring to fig. 3, optionally, estimating the actual area of the chamber based on the rate of change of the temperature in the chamber at S02 includes:
s021, the air conditioner obtains the temperature change rate v under the standard areaStandard of merit。
S022, the air conditioner calculates k ═ vPractice of-vStandard of merit)/vStandard of merit。
S023, if k < -x, the air conditioner estimates that the actual indoor area is smaller than the standard area.
And S024, if k is more than or equal to x, the air conditioner estimates that the actual indoor area is approximate to the standard area.
And S025, if k is larger than x, estimating that the actual indoor area of the air conditioner is larger than the standard area.
Wherein x is a set threshold value.
Thus, the size information of the room area can be obtained according to the actual indoor temperature change rate.
Optionally, the range of the standard area is [13m2,17m2]. More specifically, the standard area may be 15m2. Thus, the value of the standard area is reasonable.
Optionally, the value range of x is [ 15%, 25% ]. More specifically, x may take on values of 18%, 20%, 22%. In this way, an appropriate range can be divided, and the difference between the room area in the range and the standard room area is small.
Specifically, when k < -a4, the air conditioner estimates the room area to be S10.
When-a 4 ≦ k < -a3, the air conditioner estimates the room area as S9.
When-a 3 ≦ k < -a2, the air conditioner estimates the room area as S8.
When-a 2 ≦ k < -a1, the air conditioner estimates the room area as S7.
When-a 1 ≦ k < -x, the air conditioner estimates the room area as S6.
When-x ≦ k ≦ x, the air conditioner estimates the room area as S0.
When a1< k ≦ -x, the air conditioner estimates the room area as S5.
When a2< k ≦ a1, the air conditioner estimates the room area as S4.
When a2< k ≦ a3, the air conditioner estimates the room area as S3
When a3< k ≦ a4, the air conditioner estimates the room area as S2.
When k > a4, the air conditioner estimates the room area to be S1.
Wherein x < a1< a2< a3< a4, S10< S9< S8< S7< S6< S0< S5< S4< S3< S2< S1.
S0 is standard area, and S0 is in the value range of [13m2，17m2]. More specifically, S0 may be 15m2。
Therefore, the size of the room area is further refined, so that the adjustment of the temperature compensation value is more accurate.
According to fig. 4, optionally, the air conditioner determining the temperature compensation value according to the estimated actual area S03 includes:
s031, the air conditioner determines that a is 0 when the actual area in the room is similar to the standard area.
And S032, determining A by the air conditioner according to the operation mode of the air conditioner when the actual indoor area is larger than or smaller than the standard area.
S033, calculating temperature compensation value T of air conditionerCompensation＝M+A。
Wherein, M is a factory-set temperature compensation value, and A is a correction value of the temperature compensation value.
Therefore, the temperature compensation value is adjusted when the difference between the actual area and the standard area of the room is larger, so that the adjusted temperature compensation value is more in line with the actual requirement.
Optionally, M is in the range of [1 ℃, 3 ℃). More specifically, M ═ 1 ℃, 2 ℃, or 3 ℃. In this way, temperature compensation under standard room area can be satisfied.
Optionally, in the case that the actual area of the room is larger than the standard area, the air conditioner determines a according to the operation mode of the air conditioner, including:
in the case where the air conditioner operates in the cooling mode, the air conditioner determines that a < 0.
In the case where the air conditioner is operated in the heating mode, the air conditioner determines that a > 0.
Wherein the temperature compensation value is set to compensate for a target temperature set by a user.
Therefore, due to the fact that the area of the room is too large, when the air conditioner is in the cooling mode, the actual temperature in the room is often higher than the detection temperature of the air conditioner, the temperature compensation value of the target temperature is reduced, and the indoor temperature adjusted by the air conditioner is closer to the target temperature set by a user. When the air conditioner is in the heating mode, the actual temperature in the room is often lower than the detection temperature of the air conditioner, and the temperature compensation value for the target temperature is increased, so that the actual indoor temperature adjusted by the air conditioner is closer to the target temperature set by the user.
Specifically, when the room area is S5, a in the cooling mode is-b 1; in the heating mode, a ═ b 1.
When the room area is S4, the air conditioner determines that a is-b 2 in the cooling mode; in the heating mode, a ═ b 2.
When the room area is S3, the air conditioner determines that a is-b 3 in the cooling mode; in the heating mode, a ═ b 3.
When the room area is S2, the air conditioner determines that a is-b 4 in the cooling mode; in the heating mode, a ═ b 4.
When the room area is S1, the air conditioner determines that a is-b 5 in the cooling mode; in the heating mode, a ═ b 5.
Wherein 0< b1< b2< b3< b4< b 5.
Thus, the temperature compensation value is divided in more detail, so that the temperature compensation value is more accurate.
Optionally, in the case that the actual area of the room is smaller than the standard area, determining a according to the operation mode of the air conditioner includes:
in the case where the air conditioner operates in the cooling mode, the air conditioner determines that a > 0.
In the case where the air conditioner is operated in the heating mode, the air conditioner determines that a < 0.
Wherein the temperature compensation value is set to compensate for a target temperature set by a user.
In this way, the actual indoor temperature after the air conditioner is adjusted is closer to the target temperature set by the user.
Specifically, when the room area is S10, a ═ b5 in the cooling mode; and in the heating mode, A is-b 5.
When the room area is S9, the air conditioner determines that a is b4 in the cooling mode; and in the heating mode, A is-b 4.
When the room area is S8, the air conditioner determines that a is b3 in the cooling mode; and in the heating mode, A is-b 3.
When the room area is S7, the air conditioner determines that a is b2 in the cooling mode; and in the heating mode, A is-b 2.
When the room area is S6, the air conditioner determines that a is b1 in the cooling mode; and in the heating mode, A is-b 1.
Wherein 0< b1< b2< b3< b4< b 5. For example, values may be given as b1 ═ 1 ℃, b2 ═ 2 ℃, b3 ═ 3 ℃, b4 ═ 4 ℃, b5 ═ 5 ℃.
Optionally, in the case that the actual area of the room is larger than the standard area, the air conditioner determines a according to the operation mode of the air conditioner, including:
in the case where the air conditioner operates in the cooling mode, the air conditioner determines that a > 0.
In the case where the air conditioner is operated in the heating mode, the air conditioner determines that a < 0.
Wherein the temperature compensation value is set to compensate for a detected temperature of the air conditioner.
Like this, under the refrigeration mode, because the room area is too big, the temperature in the room often is higher than the temperature that the air conditioner detected, through compensating to the detection temperature for the detection temperature risees, makes the actual indoor temperature after the regulation more closely the target indoor temperature that the user set up. In the heating mode, the actual temperature in the space is often lower than the temperature detected by the air conditioner, and the detected temperature is reduced by performing temperature compensation on the detected temperature, so that the adjusted actual indoor temperature is closer to the target indoor temperature set by the user.
Specifically, when the room area is S5, a ═ b1 in the cooling mode; and in the heating mode, A is-b 1.
When the room area is S4, the air conditioner determines that a is b2 in the cooling mode; and in the heating mode, A is-b 2.
When the room area is S3, the air conditioner determines that a is b3 in the cooling mode; and in the heating mode, A is-b 3.
When the room area is S2, the air conditioner determines that a is b4 in the cooling mode; and in the heating mode, A is-b 4.
When the room area is S1, the air conditioner determines that a is b5 in the cooling mode; and in the heating mode, A is-b 5.
Wherein 0< b1< b2< b3< b4< b 5.
Therefore, the temperature compensation values of rooms with different areas can be further distinguished, so that the obtained temperature compensation values are more accurate and more accord with the actual situation.
Optionally, in the case that the actual area of the room is smaller than the standard area, the air conditioner determines a according to the operation mode of the air conditioner, including:
in the case where the air conditioner operates in the cooling mode, the air conditioner determines that a < 0.
In the case where the air conditioner is operated in the heating mode, the air conditioner determines that a > 0.
Wherein the temperature compensation value is set to compensate for a detected temperature of the air conditioner.
In this way, the adjusted actual indoor temperature can be made closer to the target indoor temperature set by the user.
Specifically, when the room area is S10, a in the cooling mode is-b 5; in the heating mode, a ═ b 5.
When the room area is S9, the air conditioner determines that a is-b 4 in the cooling mode; in the heating mode, a ═ b 4.
When the room area is S8, the air conditioner determines that a is-b 3 in the cooling mode; in the heating mode, a ═ b 3.
When the room area is S7, the air conditioner determines that a is-b 2 in the cooling mode; in the heating mode, a ═ b 2.
When the room area is S6, the air conditioner determines that a is-b 1 in the cooling mode; in the heating mode, a ═ b 1.
Wherein 0< b1< b2< b3< b4< b 5.
Therefore, the temperature compensation values of rooms with different areas can be further distinguished, so that the obtained temperature compensation values are more accurate and more accord with the actual situation.
