Description
Technical Field
The application relates to the technical field of intelligent air conditioners, in particular to a method and a device for controlling the constant temperature of an air conditioner and the air conditioner.
Background
At present, the air conditioner has been widely used as the smart machine of a common regulation indoor environment humiture, and the air conditioner not only has the function of adjusting temperature such as refrigeration heating, but also has new trend constant temperature function, and new trend constant temperature function includes: when the fresh air function of the air conditioner is independently started, in order to avoid the discomfort of a user caused by the temperature change brought to a room by the fresh air introduced from the outside, the indoor temperature compensation function can be realized through the refrigeration and heating of the air conditioner. For example: when the indoor temperature Tr is more than or equal to 18 ℃ and less than or equal to 28 ℃, the air conditioner is shut down and temperature compensation is not carried out; when Tr is less than 18 ℃, the air conditioner automatically starts a heating mode; and when Tr is more than 28 ℃, the air conditioner automatically enters a refrigeration mode. Of course, when Tr reaches the corresponding comfort temperature, the compressor stops operating, and then continues to periodically check the indoor temperature Tr, and continues to control the constant temperature operation of the air conditioner according to the indoor temperature Tr.
However, outdoor new trend directly gets into and blows indoor ring temperature sensor on, causes the indoor temperature Tr that the air conditioner detected inaccurate to make the constant temperature function open in advance, if: when the indoor actual temperature is 22 ℃ and the outdoor temperature is 0 ℃, fresh air at 0 ℃ directly enters after the fresh air function is started, so that the temperature of the room temperature sensor is sharply reduced, namely the detected indoor temperature Tr is sharply reduced. However, in practice, the room space is large, the fresh air volume is small, and the actual indoor temperature drop is not as large as that of the room temperature sensor, so that when the constant temperature function of the air conditioner is started, the actual indoor temperature may still be above 18 ℃, which causes resource waste when the air conditioner is started, and also causes large room temperature fluctuation. Or, when the actual temperature of the room reaches the corresponding comfortable temperature of 22 ℃, however, the ambient temperature sensor may detect that Tr is still maintained at a state less than 22 ℃ under the influence of fresh air, so that the air conditioner cannot exit the heating operation, thereby saving energy.

In the embodiment of the disclosure, according to the principle of heat gain and loss balance of the room where the air conditioner is located, the average temperature in the room corresponding to the introduced fresh air of the air conditioner can be determined, and the constant temperature operation of the air conditioner is controlled according to the average temperature, so that the on-off of devices such as an air conditioner compressor and the like is controlled according to the actual temperature of the room after the introduced fresh air of the air conditioner, the probability of the condition that the constant temperature function of the air conditioner is started in advance or is not quitted late is reduced, the resources are saved, the probability of temperature fluctuation in the room is also reduced, and the stability of the constant temperature function is improved.
Fig. 1 is a schematic flow chart of a method for controlling the constant temperature of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process for air conditioner thermostat control includes:
step 101: and acquiring the current air quantity of the introduced fresh air of the fresh air function starting air conditioner and the detected current first temperature.
In the embodiment of the disclosure, after the air conditioner is started and operated, the temperature of the room where the air conditioner is located can be measured at regular time or in real time by configuring the environment temperature detection device. Therefore, before the air conditioner can acquire the fresh air function and start, the detected temperature of the room, namely the second temperature, is detected. The fresh air function can be controlled to be started according to a remote control instruction of a user or an instruction issued by background equipment. At this moment, the air conditioner still can measure the temperature of the room where the air conditioner is located by configuring the environment temperature detection device, and can also detect the air speed of the air conditioner fan, the air speed detected at the current time is the current air speed, and the detected temperature is the current first temperature. Namely, the current first temperature and the current wind speed after the fresh air function starts the air conditioner to introduce fresh air are obtained.
In some embodiments, after the current wind speed of the air conditioner at the start of the fresh air function is obtained, the current air volume corresponding to the current wind speed is determined according to the stored corresponding relationship between the wind speed and the air volume. Thus, the fresh air work can be obtainedThe current air quantity of the fresh air introduced by the air conditioner can be started. In the stored corresponding relation between the wind speed and the wind volume, the corresponding fresh wind volume M (unit M) at different wind speeds3H) are different, and thus, the current air volume Mm corresponding to the current wind speed can be determined3/h。
Step 102: and determining the average temperature in the room after the fresh air function is started according to the current air volume, the current first temperature and the heat of the room where the air conditioner is located before the fresh air function is started.
The heat gain and loss of the room where the air conditioner is located are balanced, and after the fresh air function is started, the heat change in the room and the heat change of the introduced fresh air are equal. After the air conditioner introduces fresh air, outdoor fresh air directly enters and blows to the indoor ambient temperature sensor, therefore, the current first temperature detected through the air conditioner is related to the fresh air temperature, and thus, the average temperature in the room after the fresh air function is started can be determined according to the current air volume, the current first temperature and the heat of the room in which the air conditioner is located before the fresh air function is started.
The heat of the room where the air conditioner is located before the fresh air function is started is related to the temperature of the room and the volume of the room, so that the second temperature detected by the air conditioner before the fresh air function is started and the current preset volume of the room can be respectively obtained. Thus, in some embodiments, determining the average temperature in the room after the start of the fresh air function comprises: determining the current time difference delta T between the current time and the fresh air function starting time, and determining the current fresh air volume V according to the current air quantity and the current time difference delta TFresh air(ii) a According to the second temperature detected by the air conditioner before the fresh air function is started, the current preset volume of the room, the current first temperature and the current fresh air volume VFresh airDetermining the average temperature in the room after the fresh air function is started through a formula (1);
Vfresh air*(tAverage-t1)＝VRoom*(t2-tAverage) (1)
Wherein, tAverageIs the average temperature, t1Is the current first temperature, t2Is a second temperature, VRoomFor the current preset bodyAnd (4) accumulating.
If the unit of the current time difference value delta T is second, then VFresh air＝ΔT*M/3600。
In some embodiments, the current preset volume of the room may be determined according to installation environment information of the air conditioner, and the current preset volume of the room is directly determined. For example: and determining the building volume of the room as the current preset volume and storing the building volume.
Alternatively, in some embodiments, the relationship between the room temperature change rate and the preset volume of the room is pre-stored, such that the determination of the current preset volume of the room comprises: acquiring the current temperature change speed of a room in which the air conditioner is positioned after the air conditioner is started and before the fresh air function is started; and determining the current preset volume corresponding to the current temperature change speed according to the relation between the stored room temperature change speed and the preset volume of the room.
Thus, after the current preset volume is determined, the second temperature detected by the air conditioner before the fresh air is introduced is obtained, and therefore the heat V of the room where the air conditioner is located before the fresh air function is started can be obtainedRoom*t2Therefore, the average temperature t in the room after the fresh air function is started can be determined according to the heat gain-loss balance, namely the formula (1)Average。
Step 103: and controlling the air conditioner to run at constant temperature according to the average temperature.
In the embodiment of the present disclosure, the process of controlling the air conditioner constant temperature is similar to that of the related art, but the reference control temperature is different, and here, the start or the stop of the air conditioner constant temperature may be controlled according to the average temperature. In some embodiments, controlling the air conditioner to operate at a constant temperature includes: controlling the heating operation of the air conditioner under the condition that the average temperature is lower than the first set temperature; and controlling the air conditioner to perform cooling operation under the condition that the average temperature is greater than the second set temperature.
For example: if the average temperature tAverageWhen the temperature is less than 18 ℃, the air conditioner starts a heating mode to perform temperature compensation; and if the average temperature tAverageAnd if the temperature is higher than 28 ℃, the air conditioner automatically enters a refrigeration mode to perform temperature compensation. Namely, the temperature compensation is realized through the refrigeration or heating operation of the air conditioner, and the purpose of constant temperature is achieved. Of course, t is more than or equal to 18 DEG CAverageWhen the temperature is less than or equal to 2 ℃ and less than or equal to 28 ℃, temperature compensation is not needed, and the fresh air function is only needed to be kept running.
After the refrigeration or heating operation, the current wind speed, the current time and the current first temperature are still continuously sampled, so that the current wind volume corresponding to the current wind speed and the current fresh wind volume V corresponding to the current time and the current wind volume are continuously determinedFresh airContinuing to determine the volume V of the fresh air according to the formula (1)Fresh airAverage temperature t in the corresponding roomAverage. Thus, according to the average temperature tAverageAnd continuing to perform constant temperature control. In some embodiments, controlling the air conditioner to operate at a constant temperature further comprises: controlling the compressor to stop running under the conditions that the air conditioner is in a fresh air function starting and heating running state and the average temperature is higher than a first comfortable temperature; and controlling the compressor to stop running under the conditions that the air conditioner is in a fresh air function starting and refrigerating running state and the average temperature is lower than the second comfortable temperature.
For example: when the air conditioner is in a fresh air function starting and heating running state, if the determined average temperature tAverageThe temperature is more than or equal to 22 ℃, and the compressor can be controlled to stop running. And if the air conditioner is in a fresh air function starting and refrigerating running state, determining the average temperature tAverageWhen the temperature is less than or equal to 26 ℃, the compressor can also be controlled to stop running.
And naturally, after the interval is set for a period of time, sampling is continuously carried out, the average temperature is continuously determined, and the air conditioner is continuously controlled to run at a constant temperature according to the average temperature.
Therefore, in the embodiment, according to the principle of heat balance of the room where the air conditioner is located, the average temperature in the room corresponding to the introduced fresh air of the air conditioner can be determined, and the constant-temperature operation of the air conditioner is controlled according to the average temperature, so that the on-off of devices such as an air conditioner compressor and the like is controlled according to the actual temperature of the room after the introduced fresh air of the air conditioner, the probability of the situation that the constant-temperature function of the air conditioner is started in advance or is not quitted in time is reduced, resources are saved, the probability of temperature fluctuation in the room is also reduced, and the stability of the constant-temperature function is improved.
The following operational procedures are integrated into a specific embodiment to illustrate the air conditioner thermostatic control process provided by the embodiment of the invention.
In this embodiment, the air conditioner stores the corresponding relationship between the stored wind speed and the wind volume, and the relationship between the room temperature change speed and the preset room volume.
Fig. 2-1 and 2-2 are schematic flow diagrams of a method for controlling the constant temperature of an air conditioner according to an embodiment of the disclosure. With reference to fig. 2-1 and 2-2, the process for air conditioner thermostat control includes:

In this embodiment, the air conditioner may obtain the detected second temperature through the configured ambient temperature sensor, and may collect the detected second temperature at regular time or in real time, where the temperature collected each time is the corresponding current second temperature.
Step 202: determining the current temperature change speed of the room according to the current second temperature of the room, and determining the current preset volume V corresponding to the current temperature change speed according to the relationship between the stored room temperature change speed and the preset volume of the roomRoom。
Step 203: judge whether the fresh air function is started? If yes, go to step 204, otherwise, go back to step 201.
Step 204: the method comprises the steps of obtaining the current wind speed of the air conditioner started by the fresh air function and the current first temperature detected by the air conditioner.
After the air conditioner introduces fresh air, the outdoor fresh air directly enters and blows to the ambient temperature sensor, and therefore the current first temperature detected through the air conditioner is related to the temperature of the fresh air.
Step 205: and determining the current air volume corresponding to the current air speed according to the stored corresponding relationship between the air speed and the air volume.
Step 206: determining the current time difference delta T between the current time and the fresh air function starting time, and determining the current fresh air volume V according to the current air quantity and the current time difference delta TFresh air。
Step 207: the air conditioner detects the air conditioner before starting according to the fresh air functionThe previous second temperature and the current preset volume of the room, as well as the current first temperature and the current fresh air volume VFresh airAnd determining the average temperature in the room after the fresh air function is started through a formula (1).
Step 208: is the heating function of the air conditioner started? If so, go to step 209, otherwise, go to step 211.
Step 209: judging the average temperature tAverageIs ≥ 22 ℃? If yes, go to step 210, otherwise, go back to step 204.
Step 210: and controlling the compressor to stop running. Returning to step 204.
Step 211: is the cooling function of the air conditioner activated? If so, go to step 212, otherwise, go to step 213.
The air conditioner is neither heating nor cooling, and only with the fresh air function, step 213 may be executed to continue to determine whether temperature compensation is required.
Step 212: judging the average temperature tAverageIs not more than 26 ℃? If yes, go to step 210, otherwise, go back to step 204.
Step 213: judging the average temperature tAverageWhether or not to<Is 18 ℃? If so, go to step 214, otherwise, go to step 215.
Step 214: and controlling the air conditioner to perform heating operation, and returning to the step 204.
Step 215: judging the average temperature tAverageWhether or not to>Is 28 ℃? If yes, go to step 216, otherwise, go back to step 204.
I.e. t is more than or equal to 18 DEG CAverageWhen the temperature is less than or equal to 2 ℃ and less than or equal to 28 ℃, temperature compensation is not needed, and the fresh air function is only needed to be kept running.
Step 216: and controlling the air conditioner to perform cooling operation, and returning to the step 204.
Therefore, in the embodiment, according to the principle of heat balance of the room where the air conditioner is located, the average temperature in the room corresponding to the introduced fresh air of the air conditioner can be determined, and the constant-temperature operation of the air conditioner is controlled according to the average temperature, so that the on-off of devices such as an air conditioner compressor and the like is controlled according to the actual temperature of the room after the introduced fresh air of the air conditioner, the probability of the situation that the constant-temperature function of the air conditioner is started in advance or is not quitted in time is reduced, resources are saved, the probability of temperature fluctuation in the room is also reduced, and the stability of the constant-temperature function is improved.
