First, the inventive concept of the embodiment of the present invention is introduced: fig. 1 is a schematic structural diagram of a conventional air conditioner. Wherein, this air conditioner includes: the air conditioner comprises a compressor 1, an indoor fan 2, an indoor heat exchanger 3, an electronic expansion valve 4, an outdoor heat exchanger 5, a four-way reversing valve 6 and an outdoor fan 7. In the refrigeration mode or the dehumidification mode, the compressor 1 compresses a refrigerant to form a high-temperature liquid refrigerant, the high-temperature liquid refrigerant is output to the outdoor heat exchanger 5 through the four-way reversing valve 7 to release heat to form a low-temperature liquid refrigerant, the low-temperature liquid refrigerant is output to the indoor heat exchanger 3 through the electronic expansion valve 4, the refrigerant evaporates and absorbs heat in the indoor heat exchanger 3 to form a gas or gas-liquid mixed refrigerant, and then the refrigerant returns to the compressor again through the four-way reversing valve 6 to be compressed to complete a cycle. In the heating mode, the refrigerant flows in the opposite direction through the four-way reversing valve 7, so that the heating function is realized.
In the above working process of the air conditioner, the present invention finds that in the existing air conditioner control method, after the indoor environment temperature reaches and exceeds the set temperature of the air conditioner, in order to avoid discomfort of a user caused by continuous change of the indoor environment temperature, the air conditioner compressor is generally controlled to stop. For example, consider the following scenario:
the indoor ambient temperature is 32 c before the air conditioner is turned on in summer, at which time the user turns on the air conditioner to set the target temperature of the air conditioner to 23 c, and then the air conditioner starts cooling and the indoor ambient temperature starts to decrease. If the indoor environment temperature is reduced to 24 ℃, an old man comes in the room at the moment, and the old man feels that the temperature is too low, the target temperature of the air conditioner is set to be 26 ℃. At this time, the indoor ambient temperature (24 ℃ C.) exceeds the target temperature (26 ℃ C.). According to the control method in the prior art, the air conditioner should stop the operation of the compressor until the indoor environment temperature rises to above 26 ℃, and then restart the air conditioner.
However, since the indoor ambient temperature will quickly rise to above 26 ℃ after the air conditioner stops the compressor operation, the compressor will actually only stop operating for a short period of time and then need to be restarted. And due to the consideration of the pressure difference balance of the refrigeration system and the safety of the compressor, the compressor needs to be restarted after being stopped for 3 min. After the air conditioner is stopped, the compressor is restarted to enable the indoor temperature to fluctuate a lot instantly, so that discomfort of people is caused, the energy consumption of the air conditioner is increased, and energy is not saved.
In addition, when the conventional inverter air conditioner is used, the frequency of the compressor is usually calculated according to the difference between the set target temperature and the indoor environment temperature and the actual change speed of the indoor environment temperature. Therefore, in the above case, the target temperature set by human beings is suddenly changed greatly, which causes the calculated frequency of the compressor to be changed greatly, which may cause the compressor to stop working and even affect the service life of the compressor.
In order to solve the above problems, in the embodiment of the present invention, a new air conditioner control method is provided, which can keep the compressor not stopped and running stably when the target temperature set by the user changes greatly and the indoor environment temperature exceeds the target temperature, thereby avoiding the problems of poor user experience, high energy consumption, and the like in the prior art.
The first embodiment is as follows:
based on the above inventive concept, an air conditioner control method provided in an embodiment of the present invention, as shown in fig. 2, includes:
s101, detecting the indoor environment temperature.
And S102, if the indoor environment temperature exceeds the first set temperature, controlling the air conditioner to operate by taking the second set temperature as an actual target temperature.
Specifically, the first set temperature refers to a target temperature set by a user. For example, in the cooling mode, 26 ℃ is usually set as the target temperature, and 26 ℃ is the first set temperature.
In one implementation, the first set temperature further comprises a user comfort temperature that is automatically calculated according to a preset control algorithm. For example, generally, when the air conditioner is used, in addition to the target temperature set by the user, a user comfort temperature may be automatically calculated by the air conditioner according to a preset control algorithm as the first set temperature.
Wherein, indoor ambient temperature surpasss first settlement temperature, specifically includes: the indoor ambient temperature is lower than a first set temperature when the air conditioner is in a cooling mode or a dehumidifying mode. For example, in the cooling mode, the first set temperature is 26 ℃, and if the indoor ambient temperature is 25 ℃, the indoor ambient temperature exceeds the first set temperature. Indoor ambient temperature surpasss first settlement temperature, specifically still includes: the indoor ambient temperature is higher than the first set temperature when the air conditioner is in the heating mode. For example, in the heating mode, the first set temperature is 18 ℃, and if the indoor ambient temperature is 20 ℃, the indoor ambient temperature exceeds the first set temperature.
In the present invention, the actual target temperature is a target temperature for calculating the operating frequency of the compressor. As mentioned above, the frequency variation of the inverter compressor is calculated according to the difference between the set target temperature and the indoor ambient temperature, and the actual variation speed of the indoor ambient temperature. The actual target temperature in the embodiment of the present invention refers to the above target temperature.
In addition, in the embodiment of the present invention, the second set temperature is gradually changed to the first set temperature with the indoor ambient temperature as an initial value.
Specifically, the indoor environment temperature in the embodiment of the present invention may be an air inlet temperature of an air conditioner.
And controlling the operation of the air conditioner by taking the second set temperature as the actual target temperature, which specifically comprises the following steps: and controlling the operation of the air conditioner compressor by taking the second set temperature as the actual target temperature.
For example, in the cooling mode, the first set temperature is 26 ℃, if the indoor ambient temperature is 24 ℃. Firstly, controlling the operation of the air conditioner by taking 24 ℃ as an actual target temperature; then after a certain time, controlling the operation of the air conditioner by taking 24.5 ℃ as an actual target temperature; then after a certain time, controlling the operation of the air conditioner by taking 25 ℃ as an actual target temperature; then after a certain time, controlling the operation of the air conditioner by taking 25.5 ℃ as an actual target temperature; and then after a certain time, controlling the operation of the air conditioner by taking 26 ℃ as an actual target temperature. Therefore, the compressor of the air conditioner can be kept in a stable working state all the time without stopping.
Specifically, in one implementation manner, when the air conditioner is in the cooling mode or the dehumidification mode, the step S102 specifically includes:
if the indoor environment temperature is lower than the first set temperature, the indoor environment temperature is taken as an actual target temperature to control the operation of the air conditioner; and after each time period of operation, increasing the preset temperature on the basis of the actual target temperature of the previous period as the actual target temperature of the next period to control the operation of the air conditioner until the actual target temperature reaches the first set temperature.
For example, in the cooling mode or the heating mode or in the case of calling both the modes, the first set temperature, i.e., the target temperature set by the user, is denoted by Tset hereinafter; the actual target temperature is denoted by Tset'; the indoor ambient temperature is represented by Tin; the time period is denoted by t. And further:
when Tset is less than or equal to Tin, or Tset is more than or equal to Tin +2.5 ℃, Tset ═ Tset is used for controlling the compressor to work according to the existing rule.
When Tin < Tset < Tin +2.5 ℃, Tset' proceeds as follows:
tset ' (1) ═ Tin (1), Tset ' (n +1) ═ Tset ' (n) +0.5 ℃, and n is a natural number not less than 1 until Tset ═ Tset.
In this process, since the compressor is operated at a low frequency, the indoor temperature is slowly increased; meanwhile, the actual target temperature is slowly increased, so that the compressor can be stably kept in a certain frequency interval all the time, and the condition of stopping or greatly changing the frequency cannot occur.
As shown in fig. 3, initially the indoor ambient temperature is 26 ℃, the air conditioner receives a temperature rise signal from the remote controller at time T, and sets the first set temperature to 28 ℃, and then according to the method provided by the embodiment of the present invention, the air conditioner compressor is controlled to operate at 26.5 ℃ with Tset ═ Tin +0.5 ℃, and then the temperature is increased by 0.5 ℃ again in the next period, i.e., Tset ═ Tin +1 ℃, and after a plurality of periods, Tset ═ 28 ℃.
In another implementation manner, when the air conditioner is in the cooling mode or the dehumidification mode, step S102 specifically includes:
if the indoor environment temperature is lower than the first set temperature, the indoor environment temperature is taken as an actual target temperature to control the operation of the air conditioner; and after each time period of operation, increasing the preset temperature on the basis of the indoor environment temperature detected in the previous period as the actual target temperature of the next period to control the operation of the air conditioner until the actual target temperature reaches the first set temperature.
Specifically, initially, the indoor environment temperature is 26 ℃, the air conditioner receives a temperature rise signal of the remote controller at time T, the first set temperature is set to 28 ℃, and then according to the method provided by the embodiment of the present invention, the air conditioner compressor is controlled to operate at 26.5 ℃ by Tset ═ Tin +0.5 ℃, and then the indoor environment temperature is detected again in the next period, and then the air conditioner compressor is stably controlled to operate by the newly detected indoor environment. In this process, since the compressor is operated at a low frequency, the indoor temperature is slowly increased; and the actual target temperature for controlling the compressor also slowly increases along with the increase of the indoor environment temperature, so that the compressor can be stably kept in a certain frequency interval all the time without the condition of shutdown or great frequency change.
In another implementation manner, when the air conditioner is in the heating mode, step S102 specifically includes:
if the indoor environment temperature is higher than the first set temperature, the indoor environment temperature is taken as an actual target temperature to control the operation of the air conditioner; and after each time period of operation, increasing the preset temperature on the basis of the actual target temperature of the previous period as the actual target temperature of the next period to control the operation of the air conditioner until the actual target temperature reaches the first set temperature.
Exemplarily, as in the above example, the first set temperature, i.e., the target temperature set by the user, is denoted by Tset hereinafter; the actual target temperature is denoted by Tset'; the indoor ambient temperature is represented by Tin; the time period is denoted by t. And further under the heating mode:
when Tset is more than or equal to Tin, or Tset is less than or equal to Tin-2.5 ℃, Tset ═ Tset is used for controlling the compressor to work according to the existing rule.
When Tin-2.5 < Tset < Tin, Tset' proceeds as follows:
tset ' (1) ═ Tin (1), Tset ' (n +1) ═ Tset ' (n) -0.5 ℃, n is a natural number not less than 1, until Tset ═ Tset.
In this process, since the compressor operates at a low frequency, the indoor temperature slowly decreases; meanwhile, the actual target temperature is slowly reduced, so that the compressor can be stably kept in a certain frequency interval all the time, and the condition of stopping or greatly changing the frequency cannot occur.
Specifically, as shown in fig. 4, initially the indoor ambient temperature is 28 ℃, the air conditioner receives a cooling signal from the remote controller at time T, and sets the first set temperature to 26 ℃, and then according to the method provided by the embodiment of the present invention, the air conditioner compressor is controlled to operate at 25.5 ℃ with Tset ═ Tin-0.5 ℃, then the indoor ambient temperature is detected again in the next period, and then is reduced by 0.5 ℃ again in the next period, that is, Tset ═ Tin-1 ℃, and after a plurality of periods, Tset ═ 26 ℃.
In another implementation manner, when the air conditioner is in the heating mode, step S102 specifically includes:
if the indoor environment temperature is higher than the first set temperature, the indoor environment temperature is taken as an actual target temperature to control the operation of the air conditioner; and then after operating for a time period, reducing the preset temperature on the basis of the indoor environment temperature detected in the previous period as the actual target temperature of the next period to control the air conditioner to operate until the actual target temperature reaches the first set temperature.
Specifically, the indoor environment temperature is 28 ℃ at first, the air conditioner receives a cooling signal of the remote controller at the time T, the first set temperature is set to 26 ℃, then according to the method provided by the embodiment of the invention, the air conditioner compressor is controlled to operate at 25.5 ℃ with Tset ═ Tin-0.5 ℃, then the indoor environment temperature is detected again in the next period, and then the air conditioner compressor is stably controlled to operate with the newly detected indoor environment. In this process, since the compressor is operated at a low frequency, the indoor temperature is slowly decreased; and the actual target temperature for controlling the compressor is also slowly reduced along with the reduction of the indoor environment temperature, so that the compressor can be stably kept in a certain frequency interval all the time without the condition of shutdown or great frequency change.
In addition, in the above embodiment, in order to avoid that the indoor environment temperature is too low in the cooling and dehumidifying mode or too high in the heating mode, step S102 in the embodiment of the present invention specifically includes: when the air conditioner is in a cooling mode or a dehumidification mode, the indoor environment temperature is lower than a first set temperature, and the difference value between the first set temperature and the indoor environment temperature is smaller than a first threshold value; or when the air conditioner is in the heating mode, the indoor environment temperature is higher than the first set temperature, and the difference value between the indoor environment temperature and the first set temperature is smaller than a second threshold value, and the second set temperature is used as the actual target temperature to control the air conditioner to operate.
For example, in the example shown in FIG. 3, the air conditioner compressor is controlled according to the method provided by the embodiment of the present invention only when Tin < Tset < Tin +2.5 deg.C, and the air conditioner compressor is controlled according to the existing rule when Tset is less than Tin or Tset is greater than or equal to Tin +2.5 deg.C. For another example, in the example shown in FIG. 4, the air conditioner compressor is controlled according to the method provided by the embodiment of the present invention only when Tin-2.5 < Tset < Tin, and the air conditioner compressor is controlled according to the existing rule when Tset ≧ Tin or Tset ≦ Tin-2.5 ℃.
The following describes the effects of the method provided by the embodiments of the present invention with reference to experimental test results:
fig. 5 is a graph showing the operating power and frequency of a conventional inverter air conditioner compressor to which the method of the present invention is not applied. It can be seen that when the air-conditioning return air temperature (which may be taken as the indoor ambient temperature) wanders up and down at 24 ℃, the power and frequency of the air-conditioning compressor also frequently fluctuate in the corresponding region. And the total electricity consumption is 3.196 degrees in the whole test course of 5 hours and 17 minutes.
FIG. 6 is a graph of inverter air conditioner compressor operating power and power using the method provided by the embodiment of the invention. It can be seen that the number of power to frequency fluctuations of the air conditioning compressor is significantly less than in fig. 5 when the air conditioning return air temperature (which may be taken as the indoor ambient temperature) wanders up and down at 24 ℃. And the total electricity consumption is 2.303 degrees in the whole test course of 5 hours and 17 minutes.
According to the air conditioner control method and device provided by the invention, when the indoor environment temperature is detected to exceed the first set temperature, the air conditioner compressor does not need to stop working, and the air conditioner is controlled to operate by taking the second set temperature as the actual target temperature. Since the second set temperature is set to the indoor ambient temperature as the initial value, the air conditioner compressor is not stopped but operated at a low frequency, so that the indoor ambient temperature is slowly recovered. Then, along with the slow recovery of the indoor environment temperature, the actual target temperature also gradually changes to the first set temperature, so that the air conditioner compressor is always kept to work only at a lower frequency without stopping in the process of recovering the indoor environment temperature. Therefore, the problem that the compressor is frequently started and stopped in the air conditioner running process is solved.
