Description
Technical Field
The invention relates to the technical field of air treatment, in particular to an air conditioner and a control method thereof.
Background
The existing air conditioner generally utilizes a temperature detection value near an indoor unit of the air conditioner as a reference environment temperature for adjusting the running state of the air conditioner, for example, when the temperature detection value is close to a temperature set by a user, the wind speed of a fan of the indoor unit is reduced, and the frequency of a compressor of the air conditioner is reduced, so as to save energy; for another example, when the temperature detection value reaches the temperature set by the user, the compressor of the air conditioner is turned off, when the temperature detection value is greater than the preset starting temperature during cooling, the compressor is turned on, and when the temperature detection value is less than the preset starting temperature during heating, the compressor is turned on.
However, since the temperature detection value near the indoor unit cannot accurately reflect the ambient temperature near the user, the temperature near the user may not reach the set temperature, and the air conditioner may be shut down, which affects the user experience.
At present, there is a scheme of using the temperature of other areas near the indoor unit as the reference ambient temperature, for example, the remote controller is generally located at a position easily accessible by the user, the temperature of the area where the remote controller is located is relatively close to the temperature of the area where the user is located, and the temperature of the area where the remote controller is located or the temperature of other areas close to the user is used as the reference ambient temperature value when the air conditioner operates. However, if the temperature detected by the temperature sensor of the indoor unit and the temperature detected by the temperature sensor of the remote controller have large deviation, the situation of shutdown caused by large frequency change may occur; even if the deviation between the indoor temperature and the outdoor temperature is not large, when the room temperature quickly reaches the set temperature of the remote controller, if the temperature detected by the temperature sensor of the remote controller is directly used for calculating the frequency of the compressor, the indoor unit can be started and stopped frequently, and the room temperature changes greatly.

Detailed Description
First, the present embodiment provides an air conditioner 100 and a control method thereof, and the following describes the control method of the air conditioner 100 and the air conditioner 100 in detail with reference to fig. 1 to 3.
The control method of the air conditioner 100 of the present embodiment includes the steps of:
s102, acquiring a current first ambient temperature of any other area except the area where the indoor unit is located in the indoor environment where the indoor unit is located, and acquiring a current reference ambient temperature according to the current running state of the air conditioner 100, wherein the other any area is an area closer to a user than the area where the indoor unit is located;
other arbitrary areas closer to the user than the area where the indoor unit is located may be the area where the remote controller of the air conditioner 100 is located, or the area where the temperature sensor closest to the area where the user is located may be determined by distributively arranging a plurality of temperature sensors in different areas in the room in combination with an infrared identification technique, and the temperature of the area where the remote controller is located may be detected by the temperature sensor built in the remote controller.
The remote controller may have a special key, and when the user presses the special key on the remote controller, the remote controller receives the trigger signal, and transmits the temperature detected by the temperature sensor in the remote controller to the air conditioner 100 as the first ambient temperature at that time, the reference ambient temperature at this time may be based on the second ambient temperature detected by the temperature sensor of the indoor unit, that is, before step S102, the control method of this embodiment may further include receiving the trigger signal, obtaining a second ambient temperature of the area where the indoor unit is located, and using the second ambient temperature as a first reference ambient temperature according to the first operating state of the air conditioner 100, where it is also understood that, after the remote controller receives the trigger signal, the air conditioner 100 starts to execute the control method of this embodiment, and the second ambient temperature at the time of the area where the indoor unit is located provides the initial reference ambient temperature for the operation state of the air conditioner 100. And provides the reference ambient temperature for the next adjustment of the operation state of the air conditioner 100 according to the following steps S104 to S106 with the reference ambient temperature at this time and the first ambient temperature at this time.
The operation state adjustment of the air conditioner 100 may include frequency adjustment of a compressor, air speed adjustment of an indoor unit fan, and the like.
As is well known to those skilled in the art, after the operation state of the air conditioner 100 is adjusted, a certain time is required for the temperature change in the room, and therefore, after receiving the trigger signal, the remote controller does not send the first ambient temperature to the air conditioner 100 in real time, but sends the first ambient temperature to the air conditioner 100 once for a certain time period, for example, the temperature sensor detects the temperatures of any other area mentioned above for a preset number of times within a first preset number of minutes, and takes the average value of the detected temperatures for the preset number of times as the current first ambient temperature. That is, the first ambient temperature is transmitted to the air conditioner 100 once every first preset number of minutes, and the first ambient temperature may be an average value of m times of detection of the temperature sensor within the first preset number of minutes. For example, the first preset number is 3, and m is 30 times, that is, the temperature sensor samples 30 times in 3 minutes, and the average value is sent to the air conditioner 100 as the current first ambient temperature.
S104, respectively converting the current first environmental temperature and the current reference environmental temperature into a current second-multiple preset temperature share value and a current third-multiple preset temperature share value according to preset temperature share values, wherein the first preset multiple preset temperature share value is 1 ℃, and the first preset multiple is greater than 1;
in particular, this embodiment sets a predetermined temperature component value (for example, referred to as AD) on the basis of which the first ambient temperature and the reference ambient temperature are converted, wherein the first predetermined multiple of the predetermined temperature component value is 1 ℃, for example, the first predetermined multiple is 8, and then 8 AD values represent 1 degree, so that the temperature value is converted in a subdivided manner, and the accuracy of the temperature value is increased.
And S106, calculating a difference value between a preset temperature share value of the third multiple of the current time and a preset temperature share value of the second multiple of the current time to obtain a preset temperature share value of the deviation multiple of the current time, and determining the next reference environment temperature according to the operation state adjustment of the air conditioner 100 according to the preset temperature share value of the deviation multiple of the current time.
As above, in this embodiment, the temperature values are subdivided to increase the temperature precision, and the next reference ambient temperature according to the adjustment of the operation state of the air conditioner 100 is determined by taking the temperature values (the first ambient temperature) of other areas except the area where the indoor unit is located and the two temperature values of the current reference ambient temperature according to the current operation state of the air conditioner 100 as references, so as to avoid the problems of large frequency change of the compressor and large temperature change in the room caused by directly using the temperature of the area where the indoor unit is located or directly using the temperature detected by the remote controller as the reference ambient temperature in the prior art, provide more accurate reference temperature for the adjustment of the operation state of the air conditioner 100, ensure the smooth adjustment of the frequency of the compressor and the smooth rise and fall of the temperature in the room, and improve the comfort experience of the user.
As described above, the next reference ambient temperature for the operation state adjustment of the air conditioner 100 is determined according to the magnitude of the preset temperature share value of the deviation multiple of the current time, and in this embodiment, the corresponding next reference ambient temperature is determined according to three conditions of the preset temperature share value of the deviation multiple. Specifically, the method comprises the following steps:
the step of determining the next reference ambient temperature according to the adjustment of the operation state of the air conditioner 100 according to the preset temperature share value of the deviation multiple at the current time includes:
if the absolute value of the preset temperature share value of the deviation multiple of the current time is equal to or greater than the preset temperature share value of the second preset multiple, assigning the preset temperature share value of the deviation multiple of the current time to be the preset temperature share value of the second preset multiple, and taking the difference value of the preset temperature share value of the third multiple of the current time and the preset temperature share value of the deviation multiple of the current time as the reference ambient temperature of the next time; the second preset multiple is larger than the first preset multiple.
The second environment temperature is recorded as Tnhw, the first environment temperature is recorded as Tykq, the current reference environment temperature is recorded as Tnhw-now, the preset temperature fraction value of the deviation multiple is recorded as delta T, Tykq is converted into a second multiple of AD value, and Tnhw-now is converted into a third multiple of AD value. Δ T ═ Tnhw-now-Tykq, after receiving the trigger signal of the remote controller, the air conditioner 100 enters the control program for the first time, and takes the second ambient temperature Tnhw as the reference value of the reference ambient temperature, that is, Tnhw-nowInitial＝Tnhw。
If | Δ T | is equal to or greater than the second preset multiple of AD, then | Δ T | is forced to a value of AD of the second preset multiple, and Tnhw-nowThe next time＝Tnhw-nowCurrent time- Δ T. For example, the second predetermined multiple is 16, the second predetermined multipleThe number is an adjustable value, and the embodiment is not particularly limited.
In the present embodiment, | Δ T | is larger, which means that the current reference ambient temperature at which the air conditioner 100 operates is greatly different from the first ambient temperature of the area closer to the user, if the first environmental temperature is directly used as the next reference environmental temperature, the sudden change of the compressor frequency is bound to be brought, which leads to the rapid change of the temperature in the room, in order to avoid the problem, the embodiment sets an upper limit of the temperature change, i.e. forcing | Δ T | to be a second preset multiple of AD value, and using the difference between the current reference ambient temperature and | Δ T | as the next reference ambient temperature, thus, the difference between the next reference environment temperature and the current reference environment temperature is reduced, the frequency change of the compressor is relatively smooth, the temperature change in the room is not too fast, and provides a reference ambient temperature as close as possible to the area where the user is located for the adjustment of the operation state of the air conditioner 100.
If the absolute value of the preset temperature share value of the deviation multiple of the current time is equal to or less than the preset temperature share value of the third preset multiple, taking the preset temperature share value of the second multiple of the current time as the next reference environment temperature; and the third preset multiple is smaller than the second preset multiple. That is to say:
when the absolute delta T is less than or equal to the AD of the third preset multiple, Tnhw-nowThe next time＝TykqCurrent timeFor example, the third preset multiple is 4, and the third preset multiple is an adjustable value, which is not specifically limited in this embodiment. In the embodiment, | Δ T | is smaller, which means that the current reference ambient temperature of the operation of the air conditioner 100 is slightly different from the first ambient temperature of the area closer to the user, and at this time, Tykq is usedCurrent timeAs the next reference ambient temperature, the reference ambient temperature closer to the area where the user is located is provided for the adjustment of the operation state of the air conditioner 100, and the gradual adjustment of the frequency of the compressor is ensured, so that the temperature change in the room is smooth.
As mentioned above, if the absolute value of the preset temperature share value of the current deviation multiple satisfies the two conditions, the air conditioner 100 adjusts the operation state once every first preset number of minutes (as mentioned above, the air conditioner 100 receives the first ambient temperature once every first preset number of minutes).
In the following embodiment, when the absolute value of the preset temperature share value of the current deviation multiple satisfies another condition, the air conditioner 100 calculates the reference ambient temperature once per minute within a first preset number of minutes, so as to adjust the operation state once, and until the first preset number of minutes, the first ambient temperature Tykq is taken as the reference ambient temperature at the first preset number of minutes. Specifically, the method comprises the following steps:
if the absolute value of the preset temperature part value of the current deviation multiple is greater than the preset temperature part value of the third preset multiple and less than the preset temperature part value of the second preset multiple, the absolute value is calculated once per minute according to a preset formula as the reference ambient temperature of the next nth minute so as to adjust the operation state of the air conditioner 100 once per minute next time, where n is 1, 2 … … is a first preset number, and the first preset number is an integer.
In one embodiment, the predetermined formula is: tnhw-nown＝Tnhw-nown-1Int (Δ T/X), Δ T being a preset temperature component value of the deviation multiple of the current time, X being a first preset number, int being an integer, Tnhw-now being the reference ambient temperature (as mentioned above, Tnhw-now)0The second ambient temperature Tnhw is obtained when the trigger signal is received), and when n is equal to X, the preset temperature share value of the second multiple of the current time is taken as Tnhw-nowXThat is, the next adjustment of the operation state of the air conditioner 100 is to calculate the reference ambient temperature once per minute for X minutes, adjust the compressor frequency once per minute, and when X minutes is reached, take the second ambient temperature (Tnhw) acquired X minutes ago as the reference ambient temperature at the X minute. Thus, in the X minute period between the acquisition of the current first ambient temperature and the acquisition of the next first ambient temperature, the reference ambient temperature provided for the air conditioner 100 gradually and smoothly changes, rather than directly jumping to the second ambient temperature, so that the frequency of the compressor is gradually and smoothly adjusted, and the jumping change is avoided.
In an alternative embodiment, the preset formula may be determined according to a PID frequency adjustment formula of the compressor frequency, and a temperature jump change may also be avoided, thereby ensuring a smooth adjustment of the compressor frequency.
In summary, the control method of this embodiment determines different selection conditions of the next reference ambient temperature according to which the operating state of the air conditioner 100 is adjusted according to three different conditions of the preset temperature component value of the current deviation multiple, and avoids the abrupt change of the compressor frequency while ensuring that the determined reference ambient temperature is closer to the temperature of the area where the user is located, so that the compressor frequency is adjusted smoothly, the temperature in the room is raised and lowered smoothly, and the comfort of cooling and heating of the user can be greatly improved.
In the control method of this embodiment, if the first ambient temperature is not acquired for the second preset number of minutes, the current second ambient temperature is used as the next reference ambient temperature, and the temperature detection abnormality of any other area is output. That is, when the air conditioner 100 does not receive the first ambient temperature sent by the remote controller for a long time, the remote controller may have a fault or run out of power, and at this time, the control process should be ended, and the second ambient temperature of the area where the indoor unit is located is used as the reference ambient temperature, and the output temperature detection abnormality is output to remind the user to repair the remote controller or replace the battery, etc. in time. The second preset number is greater than the first preset number. Accordingly, when the air conditioner 100 is turned off or adjusted to the blowing mode, the aforementioned control process is also automatically ended.
