Position feature parameter specifically includes range information and/or angle information, and range information is target user and air conditioner The distance between, angle information is that target user deviates the positive angle of air conditioner.Wherein, face where defining air conditioner wind outlet Vertical plane is benchmark face, and a datum mark, target user are chosen in the part that datum level intersects with face where air conditioner wind outlet The line of position and datum mark is benchmark line, and the angle between reference line and datum level is defined as target user and deviates air-conditioning The positive angle of device, reference line are defined as the distance between target user and air conditioner.
Specifically, step S10 can include:
Step S11 obtains the distance between target user and air conditioner, obtains air conditioner current leaving air temp and outlet air Wind speed;
The distance between target user and air conditioner can pass through positioning device (such as radio frequency positioning dress on air conditioner Set, infrared positioning apparatus etc.) it is detected, preset coordinate system can also be established in air conditioner action space, be chosen on air conditioner Reference coordinate of one datum mark (midpoint of such as air conditioner) as air conditioner, the settable positioning dress in target user position The current measuring point coordinate of determining target user is set, above-mentioned target user and air-conditioning are calculated by reference coordinate and measuring point coordinate The distance between device.
Step S12, according to leaving air temp and apart from the measuring point temperature determined in human comfort relevant parameter;According to outlet air Wind speed and the measuring point wind speed in determining human comfort relevant parameter.
Previously according to the first quantity of leaving air temp established with distance change rule between leaving air temp and measuring point temperature Relationship can be calculated where target user according to the first quantitative relation, above-mentioned distance and current leaving air temp of foundation The measuring point temperature of position.
Since the outlet air of air conditioner is the air-flow formation in blower disturbance air duct, the running speed and air-conditioning of blower There is certain corresponding relationship between the wind speed of device.The running speed of blower is bigger, then the wind speed of air conditioner is bigger.Cause This, can determine corresponding air conditioner air-out wind speed according to the current running speed of blower.Previously according to wind speed with distance Changing rule establishes the second quantitative relation between wind speed and measuring point wind speed, according to the second quantitative relation of foundation, above-mentioned The measuring point wind speed of target user position can be calculated in distance and current wind speed.
Step S20 determines that target user institute is in place according to default human thermal comfort inductance value and human comfort relevant parameter The target measuring point temperature and target measuring point wind speed set;
Default human thermal comfort inductance value is the estimated average hotness formulated according to the thermal comfort demand of target user The setting value of index can be used as the standard value for judging whether target user is currently in comfort conditions.It is equal in current pmv value Or when in the pre-set interval where default human thermal comfort inductance value, it is believed that target user is in comfort conditions.
Wherein, after obtaining human comfort relevant parameter, current PMV can be by by human comfort relevant parameter (measuring point Temperature, relative humidity, measuring point wind speed, radiation temperature, human activity amount and clothing situation etc.) it substitutes into preset comfort sense formula and falls into a trap It obtains.Preset comfort sense formula can be specifically arranged according to specific comfort demand, current environment feature etc..
Specifically, step S20 includes: to count according to human thermal comfort inductance value, measuring point wind speed and preset comfort sense formula is preset Calculate target measuring point temperature;According to default human thermal comfort value, measuring point temperature and preset comfort sense formula, target measuring point wind is calculated Speed.
When determining target measuring point temperature, using the measuring point temperature in preset comfort sense formula as unknown quantity, human body is relaxed The other parameters such as measuring point wind speed of the appropriate relevant parameter other than measuring point temperature are as known quantity, by default human thermal comfort sense Value is used as estimated average hotness index, forms the equation for containing only that measuring point temperature is unknown quantity, finds out the solution conduct of the equation The target value of measuring point temperature is defined as target measuring point temperature by the target value of target measuring point temperature.
When determining target measuring point wind speed, using the measuring point wind speed in preset comfort sense formula as unknown quantity, human body is relaxed The other parameters such as measuring point temperature of the appropriate relevant parameter other than measuring point wind speed are as known quantity, by default human thermal comfort sense Value is used as estimated average hotness index, forms the equation for containing only that measuring point wind speed is unknown quantity, finds out the solution conduct of the equation The target value of measuring point wind speed is defined as target measuring point wind speed by the target value of measuring point wind speed.
In addition, the corresponding pass between target measuring point temperature and target measuring point wind speed can also be pre-established according to comfort demand System, different target measuring point temperature correspond to different target measuring point wind speed, and different default human thermal comfort inductance value corresponds to target Corresponding relationship between measuring point temperature and target measuring point wind speed can be different.After calculating target measuring point temperature through the above way, Target measuring point wind speed corresponding with target measuring point temperature can be determined according to corresponding relationship;Target survey can also be calculated through the above way After point wind speed, target measuring point temperature corresponding with target measuring point wind speed is determined according to corresponding relationship.
Step S30 controls air conditioner operation according to measuring point temperature, target measuring point temperature and return air inlet temperature;
According to the compressor operating frequency of measuring point temperature, target measuring point temperature and return air inlet temperature adjustment air conditioner, and/ Or, adjusting the fan operation revolving speed of air conditioner according to measuring point temperature, target measuring point temperature and return air inlet temperature.
Specifically, referring to Fig. 3, step S30 includes:
Step S31 compares measuring point temperature and target measuring point temperature, obtains the first size relation;Compare target measuring point temperature With return air inlet temperature, the second size relation is obtained;
First size relation includes that measuring point temperature is greater than target measuring point temperature, measuring point temperature is less than target measuring point temperature or survey Point temperature is equal to target measuring point temperature.
Second size relation include target measuring point temperature be less than return air inlet temperature, target measuring point temperature is greater than or draught temperature Or target measuring point temperature is equal to return air inlet temperature.
Step S32, according to the first size relation and the second size relation, adjust air conditioner compressor operating frequency and/ Or fan operation revolving speed.
The combination of different the first size relation Yu the second size relation, can correspond to its adjusting side for having different air conditioners Formula can only adjust compressor operating frequency, can also only adjust fan operation revolving speed, or can adjust compressor operation frequency simultaneously Rate and fan operation revolving speed.
Specifically, step S32 the following steps are included:
Step S321, when the current operating status of air conditioner is heating operation, when return air inlet temperature is less than target measuring point temperature Degree when measuring point temperature is less than target measuring point temperature, improves compressor operating frequency;
Since target measuring point temperature is all larger than measuring point temperature and return air inlet temperature, show the temperature in air conditioner action space It is lower, the leaving air temp of air conditioner can be improved by way of improving compressor operating frequency at this time, to make air conditioner Leaving air temp increase, more heats are distributed to air conditioner action space, to make the temperature of target user position can Reach target measuring point temperature.
Further, fan operation revolving speed can be improved, is that air conditioner is blown after improving compressor running speed preset time Hot wind out can quickly reach the position of target user, so that mesh can be rapidly achieved by making the temperature of target user position Mapping point temperature.
Step S322 is reduced when return air inlet temperature is less than target measuring point temperature, and measuring point temperature is greater than target measuring point temperature Compressor operating frequency simultaneously improves fan operation revolving speed;
When return air inlet temperature is less than target measuring point temperature, and measuring point temperature is greater than target measuring point temperature, compressor can be reduced Running frequency reduces air outlet temperature, the temperature of target user position is avoided to continue to increase, meanwhile, improve fan operation On the one hand revolving speed increases wind speed in air conditioner action space, keep the higher wind of the temperature of target user position negotiable to it The lower position of his temperature exchanges heat, and the wind lower than measuring point temperature on the other hand can be made quickly to be circulated to target user institute in place Absorption heat is set, so that making the temperature of temperature position where target user reduces, to reach target measuring point temperature.
Step S323 is improved when return air inlet temperature is greater than target measuring point temperature, and measuring point temperature is less than target measuring point temperature Fan operation revolving speed;
When return air inlet temperature is greater than target measuring point temperature, and measuring point temperature is less than target measuring point temperature, blower fortune can be improved Row revolving speed, which makes the higher air of temperature quickly be circulated to target user position, improves the temperature of the position, to make target The temperature of user position can reach target measuring point temperature.
In addition, improving blower fortune when the temperature difference of measuring point temperature and target measuring point temperature is greater than or equal to preset threshold Compressor operating frequency is improved while row revolving speed, to improve the leaving air temp of air conditioner, accelerates target user position Temperature reach the speed of target measuring point temperature.
Step S324 is reduced when return air inlet temperature is greater than target measuring point temperature, and measuring point temperature is greater than target measuring point temperature Compressor operating frequency.
When return air inlet temperature and measuring point temperature are all larger than target measuring point temperature, show entire ring in air conditioner action space The temperature in border is all higher, can reduce the leaving air temp of air conditioner by reducing compressor operating frequency at this time, target is avoided to use The temperature of family position continues to rise, and so that the temperature of target user position is reduced to target measuring point by natural heat-exchange Temperature.
S321 to step S324 through the above steps, air conditioner heat-production operation when, by according to the first size relation with Various combination between second size relation adapts to Temperature Distribution feature different in air conditioner action space, corresponding adjustment The compressor operating frequency and/or fan operation revolving speed of air conditioner, to make the temperature of target user position can reach mesh Mapping point temperature, to guarantee that different location of the user in air conditioner action space is able to satisfy its thermal comfort requirement.In addition, empty Principles of Regulation when control of the device in refrigerating operaton being adjusted to can also refer to heating operation are configured, and this will not be repeated here.
Step S40, after preset time, when air conditioner action space is unsatisfactory for comfort requirement, according to target measuring point temperature Degree and the operation of target measuring point blast velocity control air conditioner.
The length of preset time can be configured according to actual needs, and control air conditioner maintains the operation of its current state default Time can give full play to the adjustment effect of step S30 and guarantee that air conditioner action space can be at relatively steady state.
After preset time, when air conditioner action space is unsatisfactory for comfort requirement, it can be controlled according to target measuring point temperature The compressor of air conditioner is run, according to the fan operation of target measuring point blast velocity control air conditioner.
Wherein, it referring to Fig. 4, after preset time, when air conditioner action space is unsatisfactory for comfort requirement, is surveyed according to target Point temperature and target measuring point blast velocity control air conditioner operation specifically includes the following steps:
Step S41, according to target measuring point temperature and apart from the target leaving air temp for determining air conditioner, according to target measuring point wind Target wind speed fast and apart from determining air conditioner;
The distance between the first quantitative relation, target user and air conditioner according to above-mentioned foundation and target measuring point temperature The target leaving air temp of air conditioner can be calculated.According to the second quantitative relation, target user and the air conditioner of above-mentioned foundation The distance between and target measuring point wind speed the target wind speed of air conditioner can be calculated.
Step S42 determines the target frequency of the compressor of air conditioner according to target leaving air temp;According to target wind speed Determine the rotating speed of target of the blower of air conditioner;
Different target leaving air temps can be correspondingly arranged on different compressor operating frequencies, can according to target leaving air temp Determine the target frequency of corresponding compressor.Different target wind speed can be correspondingly arranged on different fan operation revolving speeds, It can determine corresponding rotating speed of target according to target wind speed.
Step S43, control compressor are run according to target frequency, and control blower is run according to rotating speed of target.
The compressor of control air conditioner is run according to target frequency, to make currently to go out wind-warm syndrome in air conditioner action space Degree can reach target leaving air temp, and the compressor for controlling air conditioner is run according to rotating speed of target, to make air conditioner action space Interior current wind speed can reach target wind speed.
Since target measuring point temperature and target measuring point wind speed are all to have comprehensively considered the mesh determined after human thermal comfort is felt Scale value has preferable harmony.Target measuring point temperature and target measuring point wind speed consider space to the attenuation of temperature, wind speed, The distance between combining target user and air conditioner determine target leaving air temp and target wind speed, pass through target leaving air temp The operation of air conditioner is controlled with what target wind speed was coordinated, to effectively guarantee that the thermal comfort of target user needs It asks.
In addition, corresponding frequency adjustment can also be determined by the temperature difference before target measuring point temperature and current measuring point temperature Amplitude increases or decreases the running frequency of compressor according to determining frequency adjustment amplitude;Can also by target measuring point wind speed and Wind speed difference between current measuring point wind speed determines corresponding revolving speed adjustment amplitude, improves or drops according to determining frequency adjustment amplitude The running frequency of low compressor.
A kind of air-conditioner control method proposed in the present embodiment, passes through human comfort relevant parameter and default human body Thermal comfort inductance value determines the target measuring point temperature and target measuring point wind speed of target user position, comprehensive measuring point temperature, mesh Mapping point temperature and return air inlet temperature control air conditioner are run, and temperature distribution is non-uniform in avoidable air conditioner action space and shadow Ring the precise control for arriving air conditioner.In addition, after preset time when air conditioner action space is unsatisfactory for comfort requirement, air-conditioning Device is according to target measuring point temperature and target measuring point wind speed coordinated operation, it can be achieved that user's different location in air conditioner action space It is able to satisfy its comfort requirement, more effectively improves the comfort of user in air conditioner action space.
Further, blower includes two axial-flow windwheels, and two axial-flow windwheels are oppositely arranged, true according to target wind speed The step of determining the rotating speed of target of the blower of air conditioner include:
