Detailed Description
Embodiments of the present application will be described in detail below, by way of example with reference to the accompanying drawings.
An air conditioner 10 according to an embodiment of the present application is described below with reference to fig. 1 to 4, including: indoor unit 100, remote controller 200, and controller. It is understood that the air conditioner 10 mentioned in the present application includes, but is not limited to, a wall-mounted air conditioner 10 and a cabinet air conditioner 10, which is mainly a variable frequency air conditioner 10.
Specifically, the indoor unit 100 is provided with a first temperature sensor; a second temperature sensor is arranged in the remote controller 200, and the remote controller 200 is in communication connection with the indoor unit 100; and, the controller is configured to: acquiring a set temperature, and acquiring a set temperature T1, a temperature T1 and a temperature T2, wherein the temperature T1 is a temperature value detected by a first temperature sensor, and the temperature T2 is a temperature value detected by a second temperature sensor when the remote controller 200 is at a first position; calculating a temperature delta T of the comfortable temperature position according to the position of the indoor unit 100, the first position of the remote controller 200, the selected comfortable temperature position, the temperature T1 and the temperature T2; according to the formula: t=t1- Δt, giving an indoor ambient temperature T; according to the difference between the set temperature and the indoor environment temperature T, the frequency of the compressor of the air conditioner 10 is adjusted in an adapting mode until the difference meets the preset range.
It will be appreciated that, as shown in fig. 2, in the application process of the air conditioner 10 of the present application, the indoor unit 100 is often hung on a wall of a room and is located on top of the wall, and the remote controller 200 may be placed in a place away from the indoor unit 100 in the indoor space, and the temperature of the place where the remote controller 200 is located may be detected. The set temperature is a temperature that is desired to be achieved in the indoor environment by adjusting the air conditioner, and may be a temperature set by a user through a remote controller or may be a temperature automatically set by the air conditioner.
Specifically, a first temperature sensor is disposed in the air conditioner 10, a second temperature sensor is disposed in the remote controller 200, the first temperature sensor disposed in the air conditioner 10 and the second temperature sensor disposed in the remote controller 200 can detect temperature at the same time point and transmit the detection result to the controller, and the controller is adapted to calculate the temperature of the current comfortable temperature position and compare with the comfortable temperature value disposed in the controller, so as to adjust the service performance of the air conditioner 10 according to the comparison result.
For example, in the heating mode, the use performance of the air conditioner 10 should be improved when the current indoor environment temperature is less than the comfort temperature, and the use performance of the air conditioner 10 should be reduced when the current indoor environment temperature is greater than the comfort temperature; in the cooling mode, the use performance of the air conditioner 10 should be reduced when the current indoor environment temperature is less than the comfort temperature, and the use performance of the air conditioner 10 should be improved when the current indoor environment temperature is greater than the comfort temperature.
Therefore, the accuracy of the indoor temperature estimated from the temperature detected by the first temperature sensor and the temperature detected by the second temperature sensor is directly related to the comfort of the air conditioner 10 in use in the indoor environment. The temperature of the comfortable position calculated by the first temperature sensor and the second temperature sensor is more accurate, so that the air conditioner 10 can be more fit with the comfort required by the user to adjust the use performance of the air conditioner 10, and the comfort felt by the user using the air conditioner 10 is improved.
That is, the first temperature sensor is used to calculate the detected temperature value T1 and the temperature value T2 detected by the second temperature sensor to obtain the indoor environment temperature T, and compare the indoor environment temperature T with the preset set temperature, and then the frequency of the compressor of the air conditioner is adjusted according to the comparison result until the difference between the set temperature and the indoor environment temperature T meets the preset range, that is, the use requirement of the user is met, and the use feeling of the user is more comfortable.
According to the air conditioner 10 of the embodiment of the application, the first temperature sensor is arranged in the indoor unit 100, the second temperature sensor is arranged in the remote controller 200, the first temperature sensor and the second temperature sensor are used for detecting the indoor temperature to obtain the temperature T1 and the temperature T2, the temperature of the current comfortable temperature position is obtained, and the running condition of the air conditioner is adjusted according to the difference value between the temperature and the set temperature, so that the service performance of the air conditioner 10 meets the requirements of users, and the use feeling of the users is improved.
In some specific embodiments, the controller is further configured to: the default first position is a position of the remote controller 200 on the floor of the indoor unit 100 facing the wall. In this way, the position detected by the remote controller 200 can be defaulted to be the first position, and the first position is located on one side, close to the ground, of the wall opposite to the indoor unit 100, so that the remote controller 200 and the air conditioner 10 are located at two opposite angles in the same horizontal plane in the indoor environment, when the indoor environment temperature is calculated, the indoor environment temperature can be calculated more accurately, the calculated indoor environment temperature is more accurate, the difference between the indoor environment temperature and the set temperature is more fit with the actual situation, and therefore, the adjustment of the use performance of the air conditioner 10 is more fit with the user requirement, so as to improve the use comfort of the air conditioner 10.
In some specific embodiments, as shown in fig. 1-3, the controller is further configured to: according to the Pythagorean theorem, the temperature DeltaT of the comfortable temperature position is calculated:
l is the length of the room, H is the installation height of the indoor unit 100, and H is the height corresponding to the selected comfort temperature position.
That is, in the use process of the air conditioner 10, it is necessary to perform advanced entry of the length of the indoor room, the installation height of the air conditioner 10, the height of the position where the comfort temperature is located, and the like, calculate the temperature Δt of the current comfort temperature position according to the temperature T1 measured by the first temperature sensor and the temperature T2 measured by the second temperature sensor, obtain the difference between the indoor environment temperature T and the set temperature according to the temperature Δt, and adjust the use performance of the air conditioner 10 according to the difference, so as to improve the use feeling of the user.
In some embodiments, the controller is further configured to:
h＝H/2。
it will be appreciated that the current indoor environment may default to a space approximating a cuboid, the indoor unit 100 and the remote controller 200 are respectively located in the cuboid space, and the temperature of the current comfortable temperature position may be considered as the midpoint of the connecting line of the positions of the indoor unit 100 and the remote controller 200 at the two opposite ends of the diagonal, which is also the midpoint in the length direction, that is, the position mentioned in the above formula, when viewed from the direction of the length section.
In some embodiments, as shown in fig. 1-3, the controller is further configured to: acquiring a temperature T3, wherein the temperature T3 is a temperature value detected by a second temperature sensor when the remote controller is at a second position; according to the position of the indoor unit 100, the selected comfortable temperature position, the temperature T1 and the temperature T3, the transverse temperature change temperature K is calculated:
K＝∣T1-T3∣*(a-a1)
a≥A/2
a is the lateral distance between the first position and the second position, a1 is the lateral distance from the selected comfort temperature position to the second position, and A is the width of the room;
in the cooling mode, according to the formula: t=t1- Δt+k, giving an indoor ambient temperature T; and/or
In the heating mode, according to the formula: t=t1- Δt-K, resulting in an indoor ambient temperature T.
It will be appreciated that the calculated position is the ideal position, i.e., the air conditioner 10 and the remote controller 200 are both located in the middle of the room. In the actual production and use process, the air conditioner 10 and the remote controller 200 cannot be completely located in the middle due to the house type structure problem or other situations, so that the calculated temperature can be corrected for the lateral temperature change, that is, the calculated lateral temperature change temperature K is calculated and is supplemented to the heating mode or the cooling mode for adjustment. In this way, in the temperature calculating process of the comfort position, the lateral temperature change temperature K is introduced, so that the temperature of the comfort position is calculated more accurately, and the controller can adjust the service performance of the air conditioner 10 more accurately through the difference between the indoor environment temperature T and the set temperature, so that the use feeling of a user is more comfortable.
In some embodiments, as shown in fig. 2 and 3, the controller is further configured to: the default second position is the corner position of the remote control 200 at the wall furthest from the first position. It will be appreciated that the second location is default to the corner location of the remote controller 200 that is the farthest 2 from the first location, so that the calculated temperature value can be more fit to the actual situation when the temperature of the second location is measured and calculated, thereby facilitating the adjustment of the performance of the air conditioner 10 by the controller.
In some specific embodiments, the controller is further configured to:
a1＝A/2。
thus, since the controller is configured to be located in the above formula, the above position is adapted to the position of the calculated comfort temperature position, and when calculating the comfort position temperature, it is necessary to make an adjustment in the height direction of the comfort position temperature so as to make it more fit to the temperature in the actual environment.
In some specific embodiments, the controller is further configured to: the temperature T3 of the remote controller 200 at the second position is not acquired during the lateral centering of the indoor unit 100 or the predetermined time, and k=0 by default. It will be appreciated that when the indoor unit 100 is in the laterally centered position, the calculated indoor ambient temperature T does not need to incorporate a lateral temperature change temperature, i.e., the calculated temperature is the temperature Δt of the actual temperature position; alternatively, when the second position of the controller is unknown or the temperature detected by the second temperature sensor in the remote controller 200 is not at the second position, k=0 may be defaulted to calculate the temperature Δt of the comfort temperature position.
In some embodiments, as shown in fig. 1-3, an air conditioner 10 includes: an indoor unit 100 and a remote controller 200, wherein the indoor unit 100 is provided with a first temperature sensor, and the remote controller 200 is provided with a second temperature sensor;
as shown in fig. 4, the control method includes:
acquiring temperature T1 and temperature T2, wherein the temperature T1 is a temperature value detected by a first temperature sensor, and the temperature T2 is a temperature value detected by a second temperature sensor when the remote controller is at a first position;
calculating a temperature delta T of the comfortable temperature position according to the position of the indoor unit 100, the first position of the remote controller 200, the selected comfortable temperature position, the temperature T1 and the temperature T2;
according to the formula: t=t1- Δt, giving the indoor ambient temperature T
According to the difference between the set temperature and the indoor environment temperature T, the frequency of the compressor of the air conditioner 10 is adjusted in an adapting mode until the difference meets the preset range.
It can be appreciated that, in the use process of the air conditioner 10, since the first temperature sensor is disposed in the indoor unit 100 and the second temperature sensor is disposed in the remote controller 200, when the indoor unit 100 and the remote controller 200 are respectively disposed in the indoor space, the first temperature sensor and the second temperature sensor are suitable for measuring the temperature in the current environment and calculating the temperature by the above formula to obtain the indoor environment temperature T, and the use performance of the air conditioner 10 is adjusted by the indoor environment temperature T, so that the use performance of the air conditioner 10 is attached to the use requirement of the user, so as to improve the use feeling of the user.
In this way, the first temperature sensor and the second temperature sensor are used for measuring the indoor temperature to obtain the temperature T1 and the temperature T2, and the difference between the indoor environment temperature T and the set temperature is calculated to adjust the frequency of the compressor of the air conditioner 10 so that the difference meets the preset range, so that the usability of the air conditioner 10 perceived by a user is more in accordance with the user requirement, and the comfort of the user using the air conditioner 10 is improved.
In some specific embodiments, in the step of acquiring the temperature T1 of the first temperature sensor and the temperature T2 of the remote controller 200 at the first position, the default first position is a position of the remote controller 200 on the floor under the facing wall of the indoor unit 100.
Thus, in order to enable the performance of the air conditioner 10 to be more effectively applied to the indoor environment when the indoor unit 100 is installed in the indoor environment, the indoor unit 100 is generally disposed at the vertical corner along the center of the indoor space, and in order to enable the remote controller 200 to more reliably feed back the detected temperature into the air conditioner 10, the process of calculating the indoor environment temperature is simplified, and the first position of the remote controller 200 may be disposed at the diagonal corner of the remote controller 200 facing the indoor unit 100.
In some specific embodiments, the step of calculating the temperature Δt of the comfort temperature location according to the location of the indoor unit 100, the first location of the remote controller 200, the selected comfort temperature location, the temperature T1 and the temperature T2 includes:
according to the Pythagorean theorem, the temperature DeltaT of the comfortable temperature position is calculated:
l is the length of the room, H is the installation height of the indoor unit 100, and H is the height corresponding to the selected comfort temperature position.
It will be appreciated that in calculating the temperature Δt of the comfort temperature position, it is necessary to consider the marginal effect of the temperature value of the position where the comfort temperature is located in the space lying in the approximate cuboid, and calculate the temperature of the comfort temperature position by feedback from the temperatures detected by the first temperature sensor and the second temperature sensor lying in the marginal.
In some embodiments, in the step of calculating the temperature Δt of the comfort temperature position according to the position of the indoor unit 100, the first position of the remote controller 200, the selected comfort temperature position, the temperature T1 and the temperature T2,
h＝H/2。
it will be appreciated that the location of the comfort temperature location is often in the middle of the indoor environment, and that the comfort temperature location may be considered to be at the very center of the indoor environment for ease of calculation when calculating the temperature of the comfort temperature location.
In some specific embodiments, the control method further comprises the steps of: acquiring a temperature T3 of the remote controller 200 when in the second position; according to the position of the indoor unit 100, the selected comfortable temperature position, the temperature T1 and the temperature T3, the transverse temperature change temperature K is calculated:
K＝∣T1-T3∣*(a-a1)
a≥A/2
a is the lateral distance between the first position and the second position, a1 is the lateral distance from the selected comfort temperature position to the second position, and A is the width of the room;
in the cooling mode, according to the formula: t=t1- Δt+k, giving an indoor ambient temperature T;
in the heating mode, according to the formula: t=t1- Δt-K, resulting in an indoor ambient temperature T.
It will be appreciated that when the above formula is used to calculate the comfort temperature position, the lateral temperature change temperature K is usually calculated, that is, the arrangement position of the indoor unit 100 is not necessarily located at the center of the indoor environment, and the longitudinal misalignment of the arrangement position of the indoor unit 100 needs to be considered, so that the calculated comfort temperature is more suitable for the actual temperature, and thus the performance of the air conditioner 10 is adjusted more suitable for the user's requirement, so as to improve the user experience.
In some specific embodiments, in the step of obtaining the temperature T3 of the remote controller 200 when in the second position, the default second position is the corner position of the remote controller 200 at the wall furthest from the first position. In this way, the second position of the remote controller 200 is defaulted to the corner position of the wall farthest from the first position of the remote controller 200, and the calculated temperature value can be more fit with the actual situation when the temperature of the second position is measured and calculated, so that the controller is convenient to adjust the using performance of the air conditioner 10.
In some embodiments, in the step of calculating the lateral temperature variation temperature K according to the position of the indoor unit 100, the selected comfort temperature position, the temperature T1 and the temperature T3,
a1＝A/2。
thus, since the controller is configured to be located in the above formula, the above position is adapted to the position of the calculated comfort temperature position, and when calculating the comfort position temperature, it is necessary to make an adjustment in the height direction of the comfort position temperature so as to make it more fit to the temperature in the actual environment.
In some embodiments, in the step of calculating the lateral temperature change temperature K according to the position of the indoor unit 100, the selected comfort temperature position, the temperature T1 and the temperature T3, the temperature T3 of the remote controller 200 at the second position is not acquired in the lateral centering of the indoor unit 100 or for a predetermined time, and k=0 is defaulted.
It will be appreciated that when the indoor unit 100 is in the laterally centered position, the calculated indoor ambient temperature does not need to incorporate a lateral temperature change temperature, i.e., the calculated temperature is the temperature Δt of the actual temperature position; alternatively, when the second position of the controller is unknown or the temperature detected by the second temperature sensor in the remote controller 200 is not at the second position, k=0 may be defaulted to calculate the temperature Δt of the comfort temperature position.
Other constructions and operations of the air conditioner 10 according to the embodiment of the present application are known to those skilled in the art, and will not be described in detail herein.
