Description

Air conditioner and control method thereof

technical field

The invention relates to the technical field of air treatment, in particular to an air conditioner and a control method thereof.

Background technique

In current air conditioners, the temperature detection value near the indoor unit of the air conditioner is generally used as the reference ambient temperature for the adjustment of the operating state of the air conditioner. For another example, when the temperature detection value reaches the user-set temperature, the compressor of the air conditioner is turned off. When cooling, when the temperature detection value is greater than the preset opening temperature, the compressor is turned on. When it is hot, when the temperature detection value is lower than the preset opening temperature, the compressor is turned on.

However, since the temperature detection value near the indoor unit cannot accurately reflect the ambient temperature near the user, it may happen that the temperature around the user does not reach the set temperature, and the air conditioner is shut down, which affects the user experience.

At present, there are solutions that use the temperature of other areas near the indoor unit as the reference ambient temperature. For example, the remote control is generally located in a position that is easily accessible by the user, and the temperature of the area where the remote control is located is relatively close to the temperature of the area where the user is located. The temperature of the area where you are located or the temperature of other areas close to the user, etc., is used as the reference value of the ambient temperature when the air conditioner is running. However, if the temperature detected by the temperature sensor of the indoor unit and the temperature detected by the temperature sensor of the remote control have a large deviation, the frequency may change greatly, resulting in a shutdown. When the temperature is fixed, if the temperature detected by the temperature sensor of the remote control is directly used to calculate the frequency of the compressor, the indoor unit may start and stop frequently and the room temperature changes greatly.

Detailed ways

This embodiment first provides an air conditioner 100 and a control method thereof. The following will specifically describe the control method of the air conditioner 100 and the air conditioner 100 in this embodiment with reference to FIGS. 1 to 3 .

The control method of the air conditioner 100 in this embodiment includes the following steps:

S102: Acquire the current first ambient temperature of any other area in the indoor environment where the indoor unit is located except the area where the indoor unit is located, and acquire the current reference ambient temperature on which the current operating state of the air conditioner 100 is based, and the other arbitrary areas are The area closer to the user than the area where the indoor unit is located;

Any other area that is closer to the user than the area where the indoor unit is located may be the area where the remote control of the air conditioner 100 is located, or, by distributing multiple temperature sensors in different areas of the room, combined with infrared identification technology, to determine the closest user The temperature of the area where the temperature sensor is located, and the temperature of the area where the remote control is located can be detected by the temperature sensor built into the remote control.

There may be a special button on the remote control. When the user presses the special button on the remote control, the remote control receives the trigger signal and sends the temperature detected by the temperature sensor in the remote control to the air conditioner 100 as the first ambient temperature at this 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 to say, before step S102, the control method of this embodiment may further include receiving a trigger signal, and then obtaining the location where the indoor unit is located. The second ambient temperature of the area at this time, the second ambient temperature is used as the first reference ambient temperature on which the first operating state of the air conditioner 100 is based. It can also be understood that after the remote controller receives the trigger signal, the air conditioner 100 starts to execute According to the control method of the embodiment, the second ambient temperature of the area where the indoor unit is located at this time provides an initial reference ambient temperature for the operating state of the air conditioner 100 . Based on the reference ambient temperature at this time and the first ambient temperature at this time, the following steps S104 to S106 are used to provide the reference ambient temperature for the adjustment of the next operating state of the air conditioner 100 .

The adjustment of the operating state of the air conditioner 100 may include adjustment of the frequency of the compressor, adjustment of the wind speed of the fan of the indoor unit, and the like.

As known to those skilled in the art, after the operating state of the air conditioner 100 is adjusted, it takes a certain time for the temperature in the room to change. Therefore, after the remote controller receives the trigger signal, it does not send the first environment to the air conditioner 100 in real time. Instead, the first ambient temperature is sent to the air conditioner 100 once within a certain period of time. For example, the temperature sensor detects the temperature of the aforementioned other arbitrary areas for a preset number of minutes within the first preset number of minutes, and sends the detected preset temperature to the air conditioner 100. The mean value of the temperature is taken as the current first ambient temperature. That is to say, the first ambient temperature is sent to the air conditioner 100 at intervals of the first preset minutes, and the first ambient temperature may be an average value detected by the temperature sensor m times within the first preset minutes. For example, the first preset number is 3, and m is 30 times, that is, the temperature sensor samples 30 times within 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 ambient temperature and the current reference ambient temperature into the current second multiple preset temperature value and the current third multiple according to the preset temperature value. a preset temperature fraction value, wherein the preset temperature fraction value of the first preset multiple is 1°C, and the first preset multiple is greater than 1;

In this embodiment, a preset temperature fraction value (for example, referred to as AD) is specially set, and both the first ambient temperature and the reference ambient temperature are converted based on the preset temperature fraction value. The first preset multiple is 1°C, for example, if the first preset multiple is 8, then 8 AD values represent 1 degree, so the temperature value is subdivided and converted to increase the accuracy of the temperature value.

S106: Calculate the difference between the current preset temperature value of the third multiple and the current preset temperature value of the second multiple to obtain the current deviation multiple preset temperature value, and according to the current The preset temperature fraction value of the deviation multiple of the next time determines the next reference ambient temperature on which the operating state of the air conditioner 100 is adjusted.

As above, in this embodiment, the temperature value is subdivided to increase the precision of the temperature, and the temperature value (the first ambient temperature) of the other area except the area where the indoor unit is located and the current operating state of the air conditioner 100 are based on this The two temperature values of the second reference ambient temperature are used as a reference to determine the next reference ambient temperature on which the operating state of the air conditioner 100 is adjusted, avoiding the direct use of the temperature of the area where the indoor unit is located or directly detected by the remote control in the prior art. The problem of large changes in compressor frequency and large changes in room temperature caused by the temperature being the reference ambient temperature provides a more accurate reference temperature for the adjustment of the operating state of the air conditioner 100, and ensures smooth adjustment of the compressor frequency and room temperature. The gentle rise and fall of the inner temperature improves the user's comfort experience.

As described above, the next reference ambient temperature adjusted by the operating state of the air conditioner 100 is the size of the preset temperature fraction value based on the current deviation multiple. In this embodiment, three types of preset temperature fraction values are specifically based on the deviation multiple. The corresponding next reference ambient temperature is determined respectively according to the situation. specifically:

The aforementioned step of determining the next reference ambient temperature on which the operating state of the air conditioner 100 is adjusted according to the preset temperature fraction value of the current deviation multiple includes:

If the absolute value of the preset temperature value of the current deviation multiple is equal to or greater than the preset temperature value of the second preset multiple, assign the preset temperature value of the current deviation multiple as the second preset multiple. The preset temperature fraction value is set, and the difference between the preset temperature fraction value of the third multiple of the current time and the preset temperature fraction value of the deviation multiple of the current time is used as the reference ambient temperature for the next time; wherein, the second preset multiple greater than the first preset multiple.

The second ambient temperature is denoted as Tnhw, the first ambient temperature is denoted as Tykq, the current reference ambient temperature is denoted as Tnhw-now, the preset temperature value of the deviation multiple is denoted as ΔT, and Tykq is converted into the AD value of the second multiple , Tnhw-now is converted to the AD value of the third multiple. ΔT=Tnhw-now-Tykq, the air conditioner 100 enters the control program for the first time after receiving the trigger signal from the remote control, and uses the second ambient temperature Tnhw as the reference value of the reference ambient temperature, that is, Tnhw-now _initial =Tnhw.

If |ΔT| is equal to or greater than the AD value of the second preset multiple, |ΔT| is forced to the AD value of the second preset multiple, and Tnhw-now _{next time} =Tnhw-now _{current time} —ΔT. For example, the second preset multiple is 16, and the second preset multiple is an adjustable value, which is not specifically limited in this embodiment.

In this embodiment, |ΔT| is larger, indicating that the current reference ambient temperature in which the air conditioner 100 is operating is quite different from the first ambient temperature in the area closer to the user. If the first ambient temperature is directly used as the next reference ambient temperature , it will definitely bring about a jump change of the compressor frequency, resulting in a rapid change of the temperature in the room. To avoid this problem, this embodiment sets an upper limit of the temperature change, that is, |ΔT| is forced to be the AD value of the second preset multiple , and the difference between the current reference ambient temperature and |ΔT| is used as the next reference ambient temperature, so as to narrow the gap between the next reference ambient temperature and the current reference ambient temperature, so that the change of the compressor frequency is relatively smooth, and the room The temperature does not change too fast, and provides a reference ambient temperature as close as possible to the area where the user is located for adjusting the operating state of the air conditioner 100 .

And if the absolute value of the preset temperature value of the current deviation multiple is equal to or smaller than the preset temperature value of the third preset multiple, the preset temperature value of the second multiple of the current time will be used as the reference environment for the next time. temperature; wherein, the third preset multiple is smaller than the second preset multiple. That is to say:

When |ΔT|≤AD of the third preset multiple, Tnhw-now _{next time} =Tykq _{current time} , for example, the third preset multiple is 4, and the third preset multiple is an adjustable value, which is not specified in this embodiment. limited. In this embodiment, |ΔT| is small, indicating that the difference between the current reference ambient temperature in which the air conditioner 100 operates and the first ambient temperature in the area closer to the user is small. In this case, the _current Tykq is used as the next reference ambient temperature , which not only provides a reference ambient temperature closer to the area where the user is located for the adjustment of the operating state of the air conditioner 100, but also ensures the smooth adjustment of the compressor frequency and the smooth temperature change in the room.

As mentioned above, if the absolute value of the preset temperature fraction value of the current deviation multiple satisfies the aforementioned two conditions, the air conditioner 100 adjusts the operating state every first preset several minutes (as mentioned above, the air conditioner The device 100 receives the first ambient temperature every first preset several minutes).

In the following embodiment, when the absolute value of the preset temperature fraction value for the current deviation multiple satisfies another condition, the air conditioner 100 calculates the reference ambient temperature every minute for the first preset number of minutes, so as to The operating state is adjusted once until the first preset number of minutes, and the first ambient temperature Tykq is used as the reference ambient temperature for the first preset number of minutes. specifically:

If the absolute value of the preset temperature fraction value of the current deviation multiple is greater than the preset temperature fraction value of the third preset multiple and smaller than the preset temperature fraction value of the second preset multiple, it will be calculated every minute according to the preset formula As the reference ambient temperature for the nth minute next time, the operation state of the air conditioner 100 is adjusted every minute next time, wherein n=1, 2...the first preset number, and the first preset number is an integer.

In one embodiment, the preset formula is: Tnhw-now _n =Tnhw-now _n-1 -int(ΔT/X), ΔT is the preset temperature fraction value of the current deviation multiple, and X is the first preset temperature Set the number, int is an integer, Tnhw-now is the reference ambient temperature (as mentioned above, Tnhw-now ₀ is the second ambient temperature Tnhw obtained when the trigger signal is received), and when n=X, the The current second multiple of the preset temperature value is taken as Tnhw-now _X , that is, the next adjustment of the operating state of the air conditioner 100 is to calculate the reference ambient temperature every minute within X minutes, and adjust the compressor every minute When the frequency reaches X minutes, the second ambient temperature (Tnhw) obtained before X minutes is used as the reference ambient temperature at the Xth minute. In this way, during the X minutes 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 changes gradually and gently, instead of jumping directly to The second ambient temperature enables the compressor frequency to be adjusted gradually and gently, avoiding jumping changes.

In an alternative embodiment, the preset formula can be determined according to the adjustment formula of the PID frequency of the compressor frequency, which can also avoid jumping changes in temperature and ensure smooth adjustment of the compressor frequency.

To sum up, the control method of this embodiment determines the different selection conditions of the next reference ambient temperature on which the operating state adjustment of the air conditioner 100 is based, respectively, according to three different situations of the preset temperature fraction value of the current deviation multiple, While ensuring that the determined reference ambient temperature is closer to the temperature in the area where the user is located, the jumping change of the compressor frequency is avoided, so that the compressor frequency is adjusted smoothly, and the temperature in the room rises and falls smoothly, which can greatly improve the comfort of cooling and heating for the user. sex.

In the control method of this embodiment, if the first ambient temperature is not obtained for the second preset consecutive minutes, the current second ambient temperature is used as the next reference ambient temperature, and the abnormal temperature detection in any other area is output. . That is to say, when the air conditioner 100 does not receive the first ambient temperature sent by the remote control for a long time, the remote control may be faulty or the battery is exhausted. The second ambient temperature in the area where the machine is located is used as the reference ambient temperature, and the abnormal temperature detection is output to remind the user to repair the remote control or replace the battery in time. , the second preset number is greater than the first preset number. Correspondingly, when the air conditioner 100 is turned off or adjusted to the air supply mode, the aforementioned control process also ends automatically.
