In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, a mechanical connection or an electrical connection, a communication between two elements, a direct connection, or an indirect connection via an intermediate medium, and the specific meaning of the terms may be understood by those skilled in the art according to specific situations.
The present invention discloses a method for controlling a temperature-sensitive air conditioner based on gender compensation, which is described in detail below with reference to the accompanying drawings. The control method disclosed in the present embodiment is directed to the summer operation of the air conditioner, and the air conditioner operates in a cooling mode. After the air conditioner is turned on, the control algorithm as disclosed in the background art is preferably executed.
An infrared sensor which can collect the absolute temperature and thermal image of the heat source is arranged on the air conditioner. The method for determining the subjective temperature and cold feeling of a heat source in an air-conditioning room through the detection value of an infrared sensor specifically comprises the following steps:
step S102, sampling the body surface temperature T of a heat source in an air-conditioning room and the environment temperature T of the air-conditioning room0Dressing index of heat source in air-conditioned room Iclo。
The heat source in the air-conditioned room is a person in the air-conditioned room. After detecting the heat source for at least two minutes, the infrared sensor starts to sample the body surface temperature T of the heat source so as to overcome the error of the outdoor environment to the body surface temperature T. The body surface temperature of the heat source is preferably forehead temperature. And a return air temperature sensor is arranged on a return air inlet of the air conditioner, and the ambient temperature of the air-conditioned room is sampled by the return air temperature sensor. Dressing index I of heat source in air conditioner roomcloMay be obtained by analysis of thermal images generated by infrared sensors. But more preferably, the dressing index I is sampledcloThe method is that the air conditioner and the server are communicated, and the server calls real-time recommended dressing information from a weather bureau database. The air conditioner stores dressing information and dressing index I in advancecloOne-to-one correspondence of (A), dressing index IcloIs a dimensionless constant.
The following selectable dressing information and dressing index IcloList relationships between.
| Dressing information | Dressing index Iclo |
| Short-sleeved shirt, trousers, shorts and shoes | 0.5 |
| Stocking, short-sleeved shirt and skirt | 0.55 |
| Shirt, trousers and socks | 0.6 |
| Shirt, dress, sock and shoe | 0.7 |
Step S103, the body surface temperature T and the environment temperature T of the air conditioner are measured0And dressing index I of heat source in air-conditioned roomcloSubstituting the following formula, and calculating the heat dissipation X of the body surface; x = (h/(1 +0.18h I)clo））（T- T0) Wherein h = hr+hc， hrFor radiative heat conductivity, hcFor convective thermal conductivity, h is preferably chosen to be 8.35W/square meter.
And step S104, judging the gender of the user represented by the heat source, wherein the subjective temperature and coldness feeling has a great relationship with the gender, and if the gender of the user is not judged, a certain degree of deviation exists in a judgment result. Therefore, firstly, the gender of the user represented by the heat source is judged by utilizing a camera arranged on the air conditioner and combining an algorithm for judging the gender by image processing in the prior art.
In step S1051, if the user is male, the body surface heat dissipation X is substituted into the following formula to calculate the gender compensation Ts：Ts=k1X+Q1(ii) a In step S1052, if the user is female, the body surface heat dissipation X is substituted into the following formula, and the gender compensation T is calculateds：Ts= Q2-k2And (4) X. Wherein k is1＜ k2，Q1＜Q2，Preferably, k is1=0.005，k2，=0.026；Q1=0.3，Q2= 0.7. I.e. if the user is male, the gender compensation Ts=0.005X +0.3, gender compensation T if the user is females=0.7-0.026And X, under the condition of the same body surface heat dissipation capacity, if the body surface heat dissipation capacity is 30, the subjective temperature and cold feeling of the male is positively corrected according to the gender, and the subjective temperature and cold feeling of the female is negatively corrected.
Step S106, calculating subjective temperature and coldness sensation Y by using the body surface heat dissipation capacity and the gender compensation, wherein Y = Y = -KsX+M+TsOf which preferred, Ks=-0.167，M=5.6。
Wherein k is1、k2、Q1、Q2、KsAnd the preferred values of M are obtained by a large number of simulation experiments.
Preferably, the subjective temperature-cold feeling grade is very cold when the subjective temperature-cold feeling Y belongs to (-4, -2.5), the subjective temperature-cold feeling grade is cold when the subjective temperature-cold feeling Y belongs to (-2.5, -1.5), the subjective temperature-cold feeling grade is comfortable when the subjective temperature-cold feeling Y belongs to (-1.5, 1.5), the subjective temperature-cold feeling grade is hot when the subjective temperature-cold feeling Y belongs to (1.5, 2.5), and the subjective temperature-cold feeling grade is very hot when the subjective temperature-cold feeling Y belongs to (2.5, 4).
By the subjective temperature and cold detection and calculation method disclosed by the embodiment of the invention, the influence of gender on the subjective temperature and cold detection result is fully considered, so that the subjective temperature and cold detection value is more accurate, and an accurate data basis is provided for subsequent control.
Fig. 2 is a flow chart showing a specific preferred embodiment of the method for calculating the subjective feeling of temperature and cold to control the operation of the air conditioner according to the method disclosed in fig. 1.
In step S201, the subjective level of coolness is determined.
In step S202, if the subjective thermal sensation level is not lower than the thermal level, it indicates that the person feels hot, and the following control strategy is executed.
Step S203, detecting a distance between the heat source and the air conditioner in real time. The distance detection is also obtained by an infrared sensor in combination with existing algorithms.
In order to make the user feel the temperature at every moment comfortably, and simultaneously play a role of cooling, the control method disclosed in this embodiment further includes the following steps:
and S204, determining the wind speed corresponding to the distance according to the corresponding relation between the distance and the wind speed, and taking the wind speed as the real-time wind speed. The phenomenon that the subjective temperature and cold feeling grade of a user jumps from a hot grade to a cold grade or below in a short time due to stimulation caused by a large amount of air outlet with too low temperature in the process of refrigerating operation is avoided. In a refrigeration environment, once an overshoot phenomenon from heat to cold occurs, it is difficult to automatically adjust to return to a comfortable state.
In the present embodiment, it is preferable to set three distance setting sections according to the area of the air-conditioned room, according to the common activity area of the person in the air-conditioned room.
Specifically, if the distance between the heat source, namely the user, and the air conditioner belongs to a first distance setting interval, determining a first set wind speed according to the relation between the distance and the wind speed, determining the first set wind speed as a real-time wind speed, and controlling the operation of the fan of the indoor unit of the air conditioner. And if the heat source, namely the distance between the user and the air conditioner belongs to a second distance setting interval, determining a second set wind speed according to the relation between the distance and the wind speed, determining the second set wind speed as a real-time wind speed, and controlling the operation of the fan of the indoor unit of the air conditioner. And if the heat source, namely the distance between the user and the air conditioner belongs to a third distance setting interval, determining a third set wind speed according to the relation between the distance and the wind speed, determining the third set wind speed as a real-time wind speed, and controlling the operation of the fan of the indoor unit of the air conditioner. Considering the relation between the air outlet temperature and the body surface temperature, the upper limit threshold values of the first distance interval, the second distance interval and the third distance interval are sequentially increased in an increasing manner, and the first set air speed, the second set air speed and the third set air speed are sequentially increased in an increasing manner. The area of a common air-conditioning room is less than or equal to 30 square meters, therefore, preferably, the first distance setting interval is set to (0, 1 m), the second distance setting interval is set to (1, 2 m), the third distance setting interval is set to (2, 3 m), the first set wind speed corresponds to a low wind gear or a breeze gear, the second set wind speed corresponds to a medium wind gear, and the third set wind speed corresponds to a high wind gear, so that a large amount of cold wind is prevented from being blown to the body surface of a user in a short distance.
Step S205, further considering the influence of the air-out temperature on the environment temperature and the human body surface temperature, considering the requirement of the refrigeration effect, detecting the air-return temperature of the air-conditioner air-return inlet and the air-out temperature of the air outlet in real time, and calculating the temperature difference between the air-return temperature and the air-out temperature as the real-time air-supply temperature difference.
And step S206, judging whether the real-time air supply temperature difference is larger than or equal to the temperature difference set value. The temperature difference set value is a temperature point obtained by a large number of air conditioner operation simulation experiments under the theoretical guidance of research personnel, and the ideal frequency corresponding to the temperature point is calculated at the same time. The return air temperature at the return air inlet of the air conditioner can be equal to the indoor ambient temperature. When the real-time air supply temperature difference is larger than or equal to the temperature difference set value, the indoor environment temperature is higher or the air supply temperature is lower.
As shown in steps S207 to S211, after the air conditioner is operated at the ideal frequency as the operation frequency, a sampling period is set. The sampling period begins and the compressor is run at the desired frequency. And generating a wind speed correction value or/and a frequency correction value according to the variation trend of the indoor temperature. And when the sampling period is finished, judging whether the subjective temperature and cold feeling grade is a 'comfortable' grade or not.
If the determination result is still at the "hot" or "very hot" level, the sampling period is started again, and the compressor controls the operation of the compressor and the indoor fan by the sum of the real-time wind speed and the wind speed correction value generated at the previous sampling period and/or the sum of the operation frequency and the frequency correction value, as shown in steps S212 and S214. If it is the "comfort" level, the above control process is exited as by step S213, and the compressor is operated at a low frequency.
As shown in steps S215 to 217, in the sampling period, the corresponding wind speed correction value and/or frequency correction value is also generated according to the distance. And executing a circulating program until the sampling period is finished, judging that the result is a 'comfortable' grade, exiting the control process, and operating the compressor according to the low frequency.
With the control method disclosed in the above embodiment, when the subjective level of the sensation of warmth and coldness of the user in the air-conditioned room is "hot" or "very hot", firstly, the wind speed is limited in a reasonable interval according to the distance between a user and the air conditioner, thereby avoiding that a large amount of cold wind is blown to the user, the temperature and cold feeling of the user is changed from a 'hot' grade to a 'cold' grade to cause overshoot, secondly, when the ambient temperature in the air conditioning room is higher or the outlet air temperature is lower, the running frequency of the compressor is adjusted to the ideal frequency, and in a sampling period or a plurality of continuous sampling periods, the wind speed or the compressor frequency is corrected and suppressed in advance during the control, so that during the temperature drop in the air-conditioned room, the subjective temperature and coldness feeling of the user can change in a gradually stable trend and keep at a 'comfortable' level, so that the user feels comfortable every moment.
When the user is far from the air conditioner, the possibility of an overshoot condition is generally low. When the air conditioner is close to the air conditioner, the possibility of occurrence of overshoot is high. Furthermore, a temperature difference set value corresponding to the distance between the user and the air conditioner is preferably generated according to the distance between the user and the air conditioner, and when the distance and the real-time air supply temperature difference both meet the conditions, a more accurate control strategy is executed.
Specifically, as shown in steps S301 to S304 in fig. 3, if the distance belongs to the first distance setting interval, it is determined whether the real-time air supply temperature difference is greater than or equal to the first temperature difference setting value. And if the real-time air supply temperature difference is larger than or equal to the first temperature difference set value, generating a corresponding frequency correction value in each sampling period, and starting to control the compressor to operate by the sum of the operation frequency and the frequency correction value in the next sampling period.
As shown in steps S401 to S404 in fig. 4, if the distance belongs to a second distance setting interval, it is determined whether the real-time air supply temperature difference is greater than or equal to a second temperature difference setting value, and if the real-time air supply temperature difference is greater than or equal to the second temperature difference setting value, a corresponding air speed correction value is generated in each sampling period, and the indoor fan is controlled to operate by the sum of the second set air speed and the air speed correction value in the next sampling period.
As shown in steps S501 to S504 in fig. 5, if the distance belongs to the third distance setting interval, it is determined whether the real-time air supply temperature difference is greater than or equal to the third temperature difference setting value. And if the real-time air supply temperature difference is larger than or equal to a third temperature difference set value, generating a corresponding frequency correction value and an air speed correction value in each sampling period, starting to control the compressor to operate by the sum of the operating frequency and the frequency correction value in the next sampling period, and controlling the indoor fan to operate by the sum of the third set air speed and the air speed correction value.
Wherein, the first temperature difference set value, the second temperature difference set value and the third temperature difference set value are sequentially increased. At relatively large distances, wind speed and frequency are allowed to adjust to a wide range.
The wind speed correction value in each sampling period is preferably generated by generating the sampling period while simultaneously generating the code ordinal number of the sampling period, and the wind speed correction value in each sampling period is a product of the wind speed correction factor and the code ordinal number of the corresponding sampling period. Preferably, the wind speed correction value is negative.
The frequency correction value in each sampling period is preferably generated by generating the coding ordinal number of the sampling period at the same time as the sampling period, and the frequency correction value in each sampling period is a product of the frequency correction factor and the coding ordinal number of the corresponding sampling period. Preferably, the frequency correction value is negative.
The sampling period is preferably in seconds.
