Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a method capable of accurately judging the indoor environment temperature, which can detect the body temperature and the change rate of an indoor human body through infrared detection equipment arranged on an air conditioner and judge the change condition of the indoor environment temperature according to the body temperature and the change rate, thereby controlling the running frequency of a compressor and improving the use comfort of a user. The parameter selection of the infrared detection device needs to adapt to the normal temperature range of the human body, and the influence of other heat sources is eliminated as much as possible, namely, the interference of the other heat sources on the human body temperature detection is avoided.
Fig. 1 is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, the method including:
s102, detecting the temperature of at least one heat source in the room.
For example, the temperature of the indoor heat source may be measured by an infrared detection device provided on the air conditioner panel, and the infrared device may also count the number of the indoor heat sources, thereby determining the number of people in the room. The embodiment is suitable for the case of one heat source or a plurality of heat sources in the room.
And S104, controlling the running frequency of the compressor according to the comparison result of the first quantity and the second quantity corresponding to the heat source.
After the air conditioner is started, the compressor is firstly operated at a certain preset frequency f.
The first number is the number of heat sources with the temperature greater than a preset temperature threshold, and the second number is the number of heat sources with the temperature less than or equal to the preset temperature threshold. Alternatively, the preset temperature threshold may be determined by a body surface temperature range when the human body feels comfortable, for example, 36 ℃ is a comfortable body temperature of the human body, and is used as the preset temperature threshold.
And if the first number corresponding to the heat source is larger than the second number, controlling the compressor to increase the first frequency to operate. The value range of the first frequency is 5-10 Hz. That is, the temperature of the indoor environment is determined by the body temperatures of most indoor heat sources, if the heat source temperature is higher than the threshold value by a larger amount, the indoor environment temperature can be preliminarily determined to be higher, and the refrigerating capacity of the air conditioner needs to be improved, and if the heat source temperature is lower than the threshold value by a larger amount, the indoor environment temperature can be preliminarily determined to be more appropriate, and the current refrigerating capacity is maintained. For example, the number n of persons with a body temperature of more than 36 ℃T＞36The number of people with the body temperature higher than or equal to 36 ℃ is nT≤36This means that the surface temperature of most people in the room is high, the body feeling is hot, and the compressor frequency can be increased from f to f + f1，f1The value range of (1) is 5-10 Hz, so that the refrigerating capacity of the air conditioner is improved, and the use comfort of a user is improved.
And if the first number corresponding to the heat source is less than or equal to the second number, controlling the compressor to continuously operate at the current frequency. For example, the number n of persons with a body temperature of more than 36 ℃T＞36N number of people with body temperature less than or equal to 36 DEG CT≤36This indicates that the body surface temperature of most indoor people is normal or low, and the body feeling is comfortable or cool, and the current compressor frequency f operation can be maintained, thereby ensuring the stable operation of the compressor and reducing the power consumption.
And S106, acquiring the temperature change rate of the heat source after the first time period of operation.
After the operation frequency of the compressor is adjusted or not adjusted in the steps, the compressor is stably operated for a first time period at the operation frequency, and then the temperature change rate of the heat source is obtained. The temperature change rate represents the absolute value of the body temperature change per minute, i.e., the body temperature change rate. Specifically, the human body temperature detected in S102 is used as an initial value, the human body temperature detected when the first time period ends is used as an end value, and the difference between the initial value and the end value is divided by the number of minutes corresponding to the first time period, so as to obtain the temperature change rate. Alternatively, the first time period may be 5 min.
And S108, controlling the running frequency of the compressor according to the temperature change rate.
Under the condition that the first number is larger than the second number, if the temperature change rate is larger than a first change rate threshold value, controlling the compressor to continuously run at the current frequency; and if the temperature change rate is less than or equal to the first change rate threshold value, controlling the compressor to increase the second frequency to operate. As mentioned above, in case the first number is greater than the second number, the first frequency operation has been increased, the cooling capacity is increased, if the temperature change rate is higher than the threshold Δ t1If the temperature of the human body is lower than the preset temperature, the human body temperature is quickly reduced, the running frequency of the compressor is not required to be continuously increased, and the current frequency can be kept to continuously run. If the temperature change rate is lower than the threshold value, the human body temperature is relatively slowly reduced, and at the moment, the operation frequency of the compressor needs to be further increased to f + f2To continue to increase the cooling capacity.
The first rate of change threshold Δ t1The value range of (a) is 0.01-0.05 ℃/min, and the second frequency f2The value range of (A) is 3-5 Hz.
Under the condition that the first number is smaller than or equal to the second number, if the temperature change rate is larger than a second change rate threshold value, controlling the compressor to reduce the third frequency to operate; and if the temperature change rate is less than or equal to the second change rate threshold value, controlling the compressor to continuously run at the current frequency. As previously mentioned, in the case where the first number is less than or equal to the second number, the operating frequency of the compressor is maintained constant if the rate of temperature change is higher than the threshold Δ t2If the temperature of the human body drops quickly, the running frequency of the compressor needs to be properly reduced to reduce the refrigerating capacity and prevent indoor users from feeling low temperature and cold. If the temperature change rate is lower than the threshold value, the body temperature of the human body is relatively slowly reduced, and the current frequency can be kept to continue running because the human body is originally in a more comfortable condition without increasing or reducing the running frequency of the compressor.
The first rate of change threshold Δ t2The value range of (a) is 0.03-0.06 ℃/min, and the third frequency f3The value range of (A) is 3-5 Hz. Optionally, the third frequency f3And a second frequency f2The values of (a) may be the same.
Alternatively, if there are a plurality of heat sources, the temperature change rate in the above step is the minimum temperature change rate corresponding to all the heat sources. The embodiment provides a step for executing the subsequent judgment of the running frequency of the compressor based on the data with the minimum body temperature change rate under the condition of a plurality of persons. Aiming at the refrigeration operation mode, the body temperature of an indoor human body is gradually reduced, the human body with the minimum body temperature change rate is the slowest human body to be cooled, the body temperature change rate of the human body is taken as the basis, if the body temperature change rate is also larger than the threshold value, the current refrigeration capacity is high, the interference of individual human body temperature abnormity on the frequency adjustment of the compressor is avoided, the operation frequency of the compressor is correspondingly controlled to be unchanged or reduced by combining the size relation between the number of indoor high-temperature human bodies and the number of indoor low-temperature human bodies, the room temperature cooling speed and the human body feeling can be balanced, and the use comfort is improved.
According to the air conditioner control method provided by the embodiment, the relative high or low of the indoor environment temperature is judged according to the comparison result of the high temperature quantity and the low temperature quantity of the indoor heat source and the temperature change rate of the heat source after the compressor runs for a certain period of time, so that the cold and warm perception of a user can be reflected more truly, the running frequency of the compressor is adjusted based on the indoor environment temperature, the running efficiency and the room temperature adjustment accuracy can be considered, and the use comfort of the user is improved.
Considering that the body temperature of the human body in the room changes with the reasons of sports, clothing, ventilation and the like, the embodiment also provides a mechanism for circularly executing temperature detection and judgment. Based on this, after controlling the operating frequency of the compressor according to the temperature change rate, the method further includes: and after the second time period of operation, continuing to perform the step of detecting the temperature of at least one heat source in the chamber. Therefore, in the running process of the air conditioner, the temperature and the change condition of the indoor heat source can be detected and judged in real time, so that the running frequency of the compressor is adjusted in real time, and the use comfort of a user is improved.
In the above-mentioned adjustment process of the compressor operation frequency, the operation frequency must not exceed the maximum operation frequency f of the compressormaxNor below the minimum operating frequency fmin。

S202, judging whether the number n of people with the body temperature of more than 36 ℃ is metT＞36The number of people with the body temperature higher than or equal to 36 ℃ is nT≤36. If yes, go to S203; if not, go to S207.
Wherein T represents the body temperature of a human body, 36 ℃ is taken as the comfortable body temperature of the human body, and if the body temperature is higher than 36 ℃, the number n of peopleT＞36The number of people with the body temperature higher than or equal to 36 ℃ is nT≤36This means that the room is largeMost people are hot, so the compressor frequency is increased from f to f + f1，f1The range of (A) is 5 to 10 Hz.
S203, raising the frequency of the compressor from f to f + f1。
S204, after running for 5min, judging whether the minimum body temperature change rate meets delta T or notmin＞△t1. If yes, go to S205; if not, go to S206.
Delta T represents the absolute value of body temperature change per minute, namely the body temperature change rate, and delta TminRepresents the body temperature change rate of the person with the smallest body temperature change rate among the n persons. After the compressor operates for 5min in a frequency increasing mode, if the minimum body temperature change rate delta Tmin＞△t1The compressor frequency remains constant, Δ t1The value range of (A) is 0.01 ℃/min-0.05 ℃/min, and the change rate delta T if the body temperature is minimummin≤△t1Compressor frequency increase f2，f2The value range of (1) is 3-5 Hz, and the temperature of the indoor human body can be judged again after 5 min.
And S205, keeping the frequency of the compressor unchanged.

When the body temperature is higher than 36 deg.CT＞36The number n of people who are not more than the body temperature and less than or equal to 36 DEG CT≤36The compressor operating frequency f remains unchanged. After 5min, the maximum rate of change of body temperature Δ tmaxGreater than Δ t2，△t2The value range of (a) is 0.03-0.06 ℃/min, the frequency of the compressor is reduced by f2Maximum rate of change of body temperature Δ tmaxNot greater than Δ t2If the temperature of the indoor human body is judged, the frequency of the compressor is kept unchanged, and the temperature of the indoor human body is judged again after the compressor runs for 5 min.
S209, reducing the frequency of the compressor from f to f-f2。
And S210, keeping the frequency of the compressor unchanged.
And S210, operating the compressor for 5 min.
Compared with the method of reflecting the change of the room temperature by the value of the temperature sensor arranged at the air inlet in the market at present, the embodiment reflects the more real cold and warm perception of the user by the indoor human body temperature and the human body temperature change rate, and the frequency control of the compressor is related to the human body temperature, the human body temperature change rate and the number of people distributed in the indoor human body temperature, so that the change of the indoor temperature can be better controlled.
