To optimize the running status of air-conditioning.
Fig. 1 is the indicative flowchart of control method according to an embodiment of the invention.Referring to Fig. 1, control method bag
Include：
Step S100, air conditioner start operation.
Step S102, detection interior whether there is user；If so, step S104 is then performed, if it is not, then performing step
S112。
Step S104, obtain user position and judge whether the distance of user and air conditioner is less than the first distance；If
It is then to perform step S106, if it is not, then performing step S108.
Step S106, the operating air velocity of blower fan keep constant.
Step S108, judges whether the distance of user and air conditioner is less than second distance；If so, step S110 is then performed,
If it is not, then perform step S112.
Step S110, the operating air velocity of blower fan heighten one grade.
Step S112, the operating air velocity of blower fan are adjusted to highest wind velocity.
It that is to say, when air conditioner, which is under running status, detects that user is not present in interior, air conditioner enters unmanned mould
Formula.The control method that air conditioner enters after unmanned pattern includes the air-out wind speed of adjustment air conditioner to highest wind velocity.In step
In S112, if the current operating air velocity of blower fan has reached highest wind velocity, blower fan is set to be maintained at highest wind velocity.This control method
By the existence according to indoor user, wind speed can be automatically adjusted in the case of nobody indoors, makes indoor environment temperature fast
Speed reaches design temperature, and does not interfere with the usage comfort of user.
In some embodiments of the invention, control method also includes detecting interior when air conditioner is under running status
When user be present, the distance between the targeted customer nearest apart from air conditioner and air conditioner are obtained, and according to targeted customer and sky
Adjust the distance adjustment air-out wind speed of device.It is most obvious due to being influenceed with the closest user of air conditioner by air conditioner air-supply, will
Closest user's identification is targeted customer, and can ensure room according to the distance between targeted customer and air conditioner regulation wind speed
Interior all users are respectively provided with preferable comfort level.
Further, the second distance in step S108 is distal to the first distance in step S104.As targeted customer and sky
Adjust the distance between device be less than first apart from when, keep the current air-out wind speed of air conditioner.When between targeted customer and air conditioner
Distance when being more than or equal to second distance, adjustment air-out wind speed to highest wind velocity.As the distance between targeted customer and air conditioner
When between the first distance and second distance (including equal to first distance), air-out wind speed is heightened one grade, if current goes out
Wind wind speed is then constant for highest wind velocity.
Thus, this control method may be such that, (be less than when user is located at the nearer position of relative air conditioner at a distance of air conditioner
First distance), air conditioner does not automatically adjust wind speed, to avoid producing noise, influences the comfort of user.When user is positioned at relative
(it is less than second distance during the slightly remote position of air conditioner at a distance of air conditioner but reaches the first distance or farther), air conditioner is suitably adjusted
Wind speed, increase one grade of operating air velocity.Now, due to having the cushion space of certain distance between air conditioner and user, only suitably
Wind speed is heightened on ground will not make air conditioner produce obvious noise or stronger air-out wind sense, and user can be avoided to realize that air conditioner blows
Deliver to the conversion of the heat exchange air-flow of surrounding air.At the same time, due to the lifting of wind speed so that blown in the unit interval from air-conditioning
Go out to the cold increase of interior, avoid cold from being gathered in the heat exchanger of air conditioner, lift its refrigerating efficiency.When user distance air-conditioning
Device farther out when (be more than or equal to second distance at a distance of air conditioner), now interior, which can be considered, is equal to nobody, air conditioner blowout change
Thermal current, without directly contacting, is only embodied, thus air conditioner can lead to user by changes such as the temperature of surrounding air and/or humidity
Cross improve wind velocity increase heat exchange air-flow amount so that indoor realization exchanges heat rapidly.
In some embodiments of the invention, the first distance and second distance can enter according to a number or exchange capability of heat for air-conditioning
The specific setting of row.First distance can be the arbitrary value between 1 meter to 2 meters, such as can be 1 meter, 1.5 meters or 2 meters etc..Second
Distance can be the arbitrary value between 2 meters to 4 meters, such as can be 2 meters, 3 meters or 4 meters etc..Preferably, the first distance and second
Distance can have 1 meter to 2 meters of difference, such as the first distance is preferably 1.5 meters, and now second distance is preferably 3
Rice.
In some embodiments of the invention, the operating air velocity of air conditioner is by the rotational speed regulation of the blower fan set in it, fortune
Sector-style speed often heightens one grade, and blower fan can heighten rotating speed 100r/min to any tachometer value between 200r/min.
In some embodiments of the invention, when in refrigeration mode or heating mode, its air outlet goes out air conditioner
Wind direction and air outlet aperture also can correspondingly controlled adjustments.
Specifically, when air conditioner works in refrigeration mode and is in unmanned pattern, the air-out direction for making air conditioner is water
It is flat upward, and the aperture of its air outlet is reached maximum opening.When air conditioner works in heating mode and is in unmanned pattern,
Make the air-out direction of air conditioner to be horizontal downward, and the aperture of its air outlet is reached maximum opening.Air-out direction and air outlet
Aperture can be controlled by the open angle of the air outlet wind deflector of air conditioner.Thus, heating air is blowed downwards or will freezed
Air is blown up to promote the relatively low cold air of indoor original temperature or the higher hot-air of temperature and the air-flow that exchanges heat rapid
Circulate, speed the heat exchange rate of heat exchange air-flow and room air, indoor temperature is rapidly reached design temperature, so as to reduce
The energy loss of air conditioner, strengthen the heat transfer effect of air conditioner.
In some embodiments of the invention, air conditioner has the compressor of changeable frequency, and control method also includes working as
When wind wind speed is highest wind velocity and air-out is maximum opening, the running frequency of compressor is reduced by one grade, to reduce compressor fortune
Capable energy expenditure.
Fig. 2 is the indicative flowchart of control method in accordance with another embodiment of the present invention.Specifically, referring to Fig. 2, control
Method processed also includes：
Step S114, the running frequency of compressor reduce by one grade.
Step S116, persistently detects the design temperature of indoor environment temperature and air conditioner, and judges that indoor environment temperature is
It is no to reach design temperature within the default very first time；If so, step S120 is then performed, if it is not, then performing step S118.
Step S118, compressor keep reducing the running frequency after one grade, and blower fan air-supply is until indoor environment temperature reaches
Design temperature.
Its running frequency is reduced a default regulating frequency by step S120, compressor at interval of a regulating cycle, directly
Restriction frequency is down to its running frequency, or until indoor environment temperature is unable to maintain that in design temperature.
Step S122, when indoor environment temperature continues without departing from design temperature within the second time, compressor stops fortune
OK, heat exchanger and blower fan are also out of service immediately, and the air-out direction and aperture of air outlet recover to the preset value of user.
Step S124, when indoor environment temperature persistently deviates design temperature within the 3rd time, compressor restarting,
And continued to run with its running frequency before out of service.
It that is to say, it is higher to go out wind velocity and the air outlet of larger opening and increase the air output of air conditioner, so as to
Increase the cold or heat that air conditioner is indoor offer.Thus, when air conditioner is transducer air conditioning, because heat exchange amount can expire
The demand of the indoor heat exchange of foot, the running frequency of air conditioner can be reduced suitably, to reduce the energy loss of air conditioner operation.
In step S114, running frequency and the thereon difference of one grade or next grade running frequency can be 0.5 hertz to 5 hertz
Arbitrary value between hereby.
In step S116, the numerical value of the very first time can be determined by the design temperature of indoor environment temperature and air conditioner.Specifically
Ground, the calculation formula of the very first time are：
t1=(Tr-Ts) * (log (Tr) -1) * 10；
Wherein, t1For the very first time, Tr is indoor environment temperature, and Ts is the design temperature of air conditioner.Specifically, t1For with
Minute be the numerical value of unit, Tr and Ts be by degree Celsius in units of numerical value.Thus, the concrete numerical value of the very first time can be according to sky
The current running status of device and indoor environment temperature is adjusted to enter Mobile state adjustment, so that the air-out wind speed of air conditioner and air-out
The regulation of the operational factors such as amount is much sooner and accurately.
In step S120, regulating cycle can be 8min to the arbitrary value between 12min, and regulating frequency can be for 0.3 hereby
Arbitrary value between 0.7 hertz.It that is to say, air conditioner, can be at interval of 10min by the fortune of compressor when performing step S120
Line frequency reduces by 0.5 hertz, to make compressor while air conditioner heat exchange efficiency is ensured in the minimum operation frequency being likely to be breached
Rate works, so as to reduce the energy expenditure of operation of air conditioner.
In step S122, the second time can be 8min to the arbitrary value between 12min.For example, can be 8min,
The numerical value such as 9min, 10min, 11min or 12min.In some embodiments of the invention, the second time was preferably 10min.
It is persistently to meet design temperature when indoor environment temperature is interior in 10min, air conditioner enters standby mode, compressor immediately
Out of service with blower fan, wind deflector recovers to user preset state, so that air-out direction and air outlet aperture recover pre- to user
If value, consequently facilitating air conditioner can blow in next startup optimization according to the default value parameter of user.
In step S124, the 3rd time can be 4min to the arbitrary value between 6min.
Further, after the running frequency of compressor reduces by one grade, if the indoor environment temperature within the default very first time
Degree reaches design temperature, then compressor reduces a default regulating frequency at interval of a default regulating time, until operation frequency
Rate is down to default restriction frequency or indoor environment temperature fails to reach design temperature in the regulating time.It that is to say, work as sky
When tune device can not meet the heat exchange demand of interior because compressor operating frequency is too low, compressor can be in time by its running frequency
Recall to disclosure satisfy that the minimum running frequency of heat exchange demand before this, and keep the running frequency.Thus, the operation of air conditioner
Frequency can dynamic regulation is optimal to heat transfer effect and energy consumption is minimum running frequency.
In some embodiments of the invention, judge that the condition that indoor environment temperature reaches design temperature can be indoor ring
Border temperature is in up and down between 1 DEG C to 3 DEG C of design temperature, such as can be above or below 1 DEG C of design temperature, 2
DEG C or 3 DEG C etc..When the temperature range is arranged to 2 DEG C up and down of design temperature, if indoor environment temperature is both not higher than setting temperature
2 DEG C of degree, also not less than 2 DEG C of design temperature, then judges that now environment temperature reaches (satisfaction) design temperature.Correspondingly, now room
The decision condition of interior environment temperature departure design temperature can be big for the difference (absolute value) of indoor environment temperature and design temperature
In equal to 2 DEG C.
In some embodiments of the invention, it is the minimum running frequency that compressor allows operation to limit frequency.Limit
It can be that compressor sucks the working frequency when degree of superheat is the first temperature at it to determine frequency.Specifically, the restriction frequency can be with
The compressor during temperature value of (being the span of the first temperature) between the suction degree of superheat for compressor is 2 DEG C to 5 DEG C
Running frequency, it is possible thereby to make air conditioner obtain higher operating efficiency.
Further, to avoid the running frequency of air conditioner from influenceing heat transfer effect after reducing, in the running frequency of compressor
After reducing by one grade first, if indoor environment temperature is not up to design temperature within the default very first time, compressor keeps mesh
Preceding running frequency, until indoor environment temperature reaches design temperature, meet indoor heat exchange demand.
Yet further, when indoor environment temperature persistently maintains design temperature, compressor within default second time
Shut down, the aperture of air-out wind speed and air outlet is recovered to the preset value of user.After compressor shutdown, when indoor environment temperature is held
The continuous design temperature that deviates reaches default 3rd time, and air conditioner restarts operation with the running frequency before compressor shutdown.
It that is to say, when air conditioner completes the system to interior under the adjustment control of this control method with relatively low running frequency
After cold/heating, compressor can enter the state shut down, and the control module such as master control borad of air conditioner can stop compressor in entrance
Running frequency before machine state is obtained and recorded, with environment temperature indoors deviate design temperature after, directly with shut down/it is standby before
Running frequency restarting operation, readjusted without extra time, so as to ensure the heat exchange efficiency of air conditioner and low energy
Consumption.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
Example property embodiment, still, still can be direct according to present disclosure without departing from the spirit and scope of the present invention
It is determined that or derive many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognized
It is set to and covers other all these variations or modifications.
