Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below with reference to drawings and Examples, the present invention is described in further detail.
Refer to Fig. 1, this figure is depicted as the main flow chart of wall-hanging air conditioner control method of the present invention first embodiment.
As shown in Figure 1, the flow process of this embodiment to the method that air-conditioner controls comprises the steps:
Step 101: receive airconditioning control instruction.
Step 102: whether the control refrigeration that determining step 101 receives is refrigerated energy-saving comfortable cooling.If NO, step 103 is performed; Otherwise, perform step 104.
User can by the instruction of convertible frequency air-conditioner control panel input airconditioning control, also airconditioning control instruction can be inputted by convertible frequency air-conditioner remote controller, can also by convertible frequency air-conditioner control of intelligent terminal, as being provided with the smart mobile phone input airconditioning control instruction of convertible frequency air-conditioner control APP.No matter adopt which kind of command input device, be provided with the specified button that refrigerated energy-saving comfortable cooling is special all on the input.User presses this button, just can trigger convertible frequency air-conditioner and enter refrigerated energy-saving comfortable running mode, realizes the not only energy-conservation but also refrigeration control that temperature adjustment is comfortable.Thus, user is facilitated whether to perform refrigerated energy-saving comfort mode from main separation.If convertible frequency air-conditioner has received and controlled button and press, and judges it is that button corresponding to refrigerated energy-saving comfortable cooling is pressed, represent that user have input the comfortable instruction of refrigerated energy-saving, then entered the comfortable instruction of refrigerated energy-saving that step 104 starts.
Step 103: if step 102 judges that received airconditioning control instruction is not the comfortable instruction of refrigerated energy-saving, then according to original VFC Schema control convertible frequency air-conditioner.Then, go to step 101, keep and receive airconditioning control instruction and judge.
Original VFC pattern refers to the control model that convertible frequency air-conditioner has before setting up refrigerated energy-saving comfort mode.Original VFC pattern not only comprises the process according to FREQUENCY CONTROL compressor operating, also comprises the aperture running, control according to the degree of superheat electric expansion valve according to user's wind speed setting control room inner blower and outdoor fan, etc.And, preferably adopt Fig. 3 flow process to realize to the process that compressor frequency controls in original VFC pattern, refer to the follow-up description to Fig. 3.
Step 104: if step 102 judges that received airconditioning control instruction is the comfortable instruction of refrigerated energy-saving, enter the comfortable control model of refrigerated energy-saving.First, detect current indoor temperature, make comparisons with setting indoor environment temperature threshold value.
Setting indoor environment temperature threshold value has been written in the memory of air-conditioner controller when convertible frequency air-conditioner dispatches from the factory.General, this setting indoor environment temperature threshold value is not modifiable for user, because user is difficult to implication and the function of knowing this threshold value, if revised arbitrarily by user, can increase energy consumption on the contrary, reduce refrigeration comfortableness.This threshold value can by personnel or other professionals carry out numerical value amendment by operations such as the upgradings to air-conditioner controller after sale.And, this setting indoor environment temperature threshold value be most of human body sense comparatively comfortable, a too hot temperature value can not be felt, be such as set as 28 DEG C.Current indoor temperature refers to a real time temperature of environment space current time residing for convertible frequency air-conditioner, can be detected by the temperature sensor being arranged on air-conditioning air inlet.Enter the comfortable control model of refrigerated energy-saving, detect current indoor temperature, and do comparing of size with setting indoor environment temperature threshold value.
Step 105: judge whether current indoor temperature is less than setting indoor environment temperature threshold value.If so, step 106 is performed; Otherwise, perform step 103.
If current indoor temperature is not less than setting indoor environment temperature threshold value, shows that indoor environment temperature is higher, then perform step 103, according to original VFC Schema control convertible frequency air-conditioner, can decline fast to make indoor temperature.And, in the process according to original VFC Schema control convertible frequency air-conditioner, go to step 104, continue to detect current indoor temperature, and make comparisons with setting indoor environment temperature threshold value.
Step 106: if current indoor environment temperature is less than setting indoor environment temperature threshold value, shows that indoor environment temperature is low, may be close to design temperature.And when close to design temperature, compressor will low-frequency operation.Now, the compressor target frequency gone out according to original VFC mode computation is obtained.
Step 107: whether the compressor target frequency that determining step 106 obtains is less than the first setting compressor frequency.If so, step 108 is performed; If not, show that user's design temperature is lower, current indoor temperature, still higher than user's design temperature, needs to lower the temperature further, thus, goes to step 103, according to original VFC Schema control convertible frequency air-conditioner, can decline fast to make indoor temperature.And, in the process according to original VFC Schema control convertible frequency air-conditioner, go to step 104, continue to detect current indoor temperature, and make comparisons with setting indoor environment temperature threshold value.
Step 108: if the compressor target frequency that step 106 obtains is less than the first setting compressor frequency, controls compressor and runs with the first setting compressor frequency, meanwhile, control outdoor fan and run with setting speed.
When the compressor target frequency that Practical Calculation goes out is less than the first setting compressor frequency, controls compressor and carry out low frequency limit frequently, make its compressor low-limit frequency be the first setting compressor frequency, instead of run according to the compressor target frequency that Practical Calculation goes out.
Wherein, first setting compressor frequency is that to dispatch from the factory at convertible frequency air-conditioner be the fixed frequency be written in the memory of air-conditioner controller, and this frequency is the value obtained through theoretical research and a large amount of comprehensive experiment by research staff, it is the reasonable frequency value can taking into account low energy consumption and refrigeration comfortableness.Such as, this first setting compressor frequency is 15Hz.When the compressor target frequency gone out according to original VFC mode computation is lower than 15Hz, show that real-time indoor environment temperature is close to user's design temperature, without the need to more refrigerating capacity.But run according to this frequency lower than 15Hz if control compressor, due to underfrequency, its refrigerating capacity is extremely weak, even can not play any refrigeration.Now, although compressor is low-frequency operation, still consume certain electricity, and its refrigerating capacity is extremely weak, thus causes compressor running to be now almost a pure power consumption and do not have the process of refrigeration, from Energy Efficiency Ratio angle, power consumption is large.Moreover, because compressor output is extremely weak, can not maintain the stable of indoor temperature, make fluctuations in indoor temperature large, temperature affects comfortableness after rising.And temperature rise after, need control compressor again high frequency running lower the temperature, therefore, from whole process of refrigerastion, power consumption is large.
And in this embodiment, when the compressor target frequency that Practical Calculation goes out is less than the first setting compressor frequency, controls compressor and carry out low frequency limit frequently.Compressor runs under this first setting compressor frequency, can produce and maintain the stable refrigerating capacity of indoor temperature, make indoor temperature be stabilized in user's design temperature, improve comfortableness.And because indoor temperature is stablized, compressor again high frequency fortune lengthens cycle turnover.Thus, Energy Efficiency Ratio, in whole process of refrigerastion, compressor power consumption is little, thus reduces the energy consumption of air conditioner refrigerating.
And, in this limit frequently running, control outdoor fan and run with fixing setting speed, instead of according to original VFC mode operation, the balance of whole refrigeration system can be kept when compressor limit frequency, stablize indoor temperature further, improve the comfortableness of indoor temperature.Same, setting speed is that to dispatch from the factory at convertible frequency air-conditioner be the fixed value be written in the memory of air-conditioner controller, and this value is the value obtained through theoretical research and a large amount of comprehensive experiment by research staff.
In the process performing step 108, still continue the detection and the decision process that perform step 104.
In a word, in refrigerating of convertible frequency air conditioner running, the detection of continuous execution step 101, step 102, step 104, step 105 and step 107 and decision process, meeting the control which condition is which condition just enter, just exiting corresponding control when not meeting certain condition.
Refer to Fig. 2, this figure is depicted as the flow chart of wall-hanging air conditioner control method of the present invention second embodiment.In this embodiment, the compressor of air-conditioner is the compressor of changeable frequency, and the electric expansion valve that to be aperture controlled of the throttle part in the refrigerating of convertible frequency air conditioner circulatory system.
As shown in Figure 2, the flow process of this embodiment to the method that air-conditioner controls comprises the steps:
Step 201: receive airconditioning control instruction.
Step 202: whether the control refrigeration that determining step 201 receives is refrigerated energy-saving comfortable cooling.If NO, step 203 is performed; Otherwise, perform step 204.
Step 203: if step 202 judges that received airconditioning control instruction is not the comfortable instruction of refrigerated energy-saving, then according to original VFC Schema control convertible frequency air-conditioner.Then, go to step 201, keep and receive airconditioning control instruction and judge.
Step 204: if step 202 judges that received airconditioning control instruction is the comfortable instruction of refrigerated energy-saving, enter the comfortable control model of refrigerated energy-saving.First, detect current indoor temperature, make comparisons with setting indoor environment temperature threshold value.
Step 205: judge whether current indoor environment temperature is less than setting indoor environment temperature threshold value.If so, step 206 is performed; Otherwise, perform step 203.
Step 206: if current indoor environment temperature is less than setting indoor environment temperature threshold value, obtain the compressor target frequency gone out according to original VFC mode computation.
Step 207: whether the compressor target frequency that determining step 206 obtains is less than the first setting compressor frequency.If so, step 209 is performed; Otherwise, perform step 208.
Step 208: if step 206 judges that compressor target frequency is not less than the first setting compressor frequency, then judge whether compressor target frequency is less than the second setting compressor frequency.If so, step 210 is performed; Otherwise, go to step 203, still continue the detection and the decision process that perform step 204.
Step 209: if the compressor target frequency that step 206 obtains is less than the first setting compressor frequency, controls compressor and runs with the first setting compressor frequency, meanwhile, control outdoor fan and run with setting speed.Then, step 210 is performed.
The specific implementation process of above-mentioned steps 201 to step 207 and step 209, principle and object are similar with the corresponding step of Fig. 1 embodiment, and no longer specifically set forth, details can with reference to the description of figure 1.
By step 209, add step 208 with Fig. 1 embodiment unlike, this Fig. 2 embodiment and compressor target frequency and second are set the process that compressor frequency makes comparisons.Wherein, the second setting compressor frequency is larger than the first setting compressor frequency, and such as, the first setting compressor frequency is 15Hz, then the second setting compressor frequency is 20Hz.And, to set compressor frequency similar with first, this the second setting compressor frequency is also that to dispatch from the factory at convertible frequency air-conditioner be the fixed frequency be written in the memory of air-conditioner controller, and this frequency is the value obtained through theoretical research and a large amount of comprehensive experiment by research staff, it is the reasonable frequency value can taking into account low energy consumption and refrigeration comfortableness.
Step 210: this step is transferred by step 208 and step 209, also be, as long as step 206 is less than the second setting compressor frequency according to the compressor target frequency that original VFC mode computation goes out, then control the aperture of the electric expansion valve of convertible frequency air-conditioner for setting aperture.
Wherein, setting aperture is that to dispatch from the factory at convertible frequency air-conditioner be the fixed value be written in the memory of air-conditioner controller, and this value is the value obtained through theoretical research and a large amount of comprehensive experiment by research staff.Such as, first setting compressor frequency be 15Hz, second setting compressor frequency be 20Hz time, setting aperture be 100 steps.When the compressor target frequency gone out according to original VFC mode computation is less than the second setting compressor frequency, no longer control according to the aperture of original VFC pattern to electric expansion valve, but the aperture controlling electric expansion valve is fixed.And, when compressor frequency is less than the second setting compressor frequency, this setting aperture is less than the aperture calculated according to original VFC pattern, because original control mode is the degree of superheat adjust valve, more desirably can not realize refrigeration by control valve aperture at low frequency.And this embodiment controls electric expansion valve for fixing aperture when compressor low-frequency operation, suitable refrigerating capacity can be obtained and make air conditioning exhausting proper temperature.
Step 211: judge compressor runs whether arrive the first setting-up time with the actual motion frequency being less than the second setting compressor frequency.If so, step 212 is performed; Otherwise, continue timing, until arrive the first setting-up time.
Step 212: if compressor runs arrival first setting-up time with the actual motion frequency being less than the second setting compressor frequency, the actual motion frequency controlling compressor rises to the 3rd setting compressor frequency, and continuous service second setting-up time.
Step 213: when compressor runs arrival the second setting-up time according to the 3rd setting compressor frequency, then return to the operation of the reason frequency before rising.
The object performing above-mentioned steps 211 to step 213 is to carry out protecting control to the running of compressor low frequency and continuous, avoiding the long-time low-frequency operation of compressor and damage compressor.Wherein, first setting-up time, the second setting-up time and the 3rd setting compressor frequency are all that to dispatch from the factory at convertible frequency air-conditioner be the fixed value be written in the memory of air-conditioner controller, and this value is the value obtained through theoretical research and a large amount of comprehensive experiment by research staff.Such as, the first setting-up time is 30min, and the second setting-up time is 10s, and the 3rd setting compressor frequency is 30Hz.After compressor is with the 30min that operates continuously lower than the actual motion frequency of the second setting compressor frequency 20Hz, the running frequency of enforce compression machine rises to 30Hz, and continuous service 10s.Then return to the original frequency before rising then.
In the process performing above-mentioned compressor limit frequency and low-frequency operation protection, still continue the detection and the decision process that perform step 204.
Certainly, in refrigerating of convertible frequency air conditioner running, still constantly can perform detection and the decision process of step 201, step 202, step 204, step 205, step 207 and step 208, meeting the control which condition is which condition just enter, just exiting corresponding control when not meeting certain condition.
No matter be Fig. 1 embodiment or Fig. 2 embodiment, when entering the comfortable control procedure of refrigerated energy-saving, control similar with existing convertible frequency air-conditioner, need to pre-set airconditioning control parameter, as user's design temperature, wind speed setting, air supply direction etc., the comfortable control procedure of refrigerated energy-saving will control according to these airconditioning control Parameters on Compressive machine, indoor fan, outdoor fan, wind deflector etc., meet consumers' demand.As an optimal control process, for a concrete convertible frequency air-conditioner, there is mating of a best controling parameters and control performance in the comfortable control of refrigerated energy-saving.In order to provide Optimal Control performance, before air-conditioning dispatches from the factory, the optimization control parameter realizing optimum control performance of this air-conditioning is prefixed in it stores, this optimization control parameter is airconditioning control parameter by default, at user's using air-condition and when have selected the comfortable control model of refrigerated energy-saving, Air-Conditioning Control Panel or air cnoditioner remote controller display screen demonstrate acquiescence airconditioning control parameter, understands best controling parameters for user and control benchmark.
But for meeting the individual demand of user, acquiescence airconditioning control parameter is not modifiable, and user using the default control parameters of display as with reference to benchmark, can reset controling parameters according to self-demand.
Now, after receiving airconditioning control refrigeration and be refrigerated energy-saving comfortable cooling and showing acquiescence airconditioning control parameter, if the airconditioning control parameter reset detected in setting setup times, then perform the comfortable control procedure of refrigerated energy-saving according to the airconditioning control parameter reset.And if in setting setup times, the airconditioning control parameter reset do not detected, then will perform refrigerated energy-saving comfortable control procedure according to airconditioning control parameter of submerging.
Refer to Fig. 3, this figure is depicted as original VFC pattern particular flow sheet in Fig. 1 and Fig. 2.
First, briefly explain the technical thought of original VFC pattern: for wall-hanging air conditioner, installation site is relatively high in room, be generally all arranged on the position on distance about 2 meters, ground.Indoor temperature transmitter air-conditioning being used for detect indoor temperature is generally positioned on air-conditioner air inlet or evaporimeter, and thus, the air themperature that indoor temperature transmitter detects is the temperature of the air of about the 2 meters At The Heights in distance ground.And in room, user's main activities Spatial General 6 R is the area of space from ground to distance about 1.35 meters, ground.According to the theory of molecular motion, cold air moves downward.So, when air-conditioner running refrigerating pattern, because cold air sinks, the temperature of upper air is also than the temperature drift of lower air.Thus the temperature drift that indoor temperature transmitter detects is in the temperature in user's main activities space.This embodiment is based on this phenomenon, and this angle of temperature itself is set out indoor, proposes a kind of air-conditioner control technology scheme taking into account the low-power consumption energy saving of thermoregulator comfortableness and air-conditioner in air conditioner chamber, and is applied in original VFC pattern.Specifically, in original VFC pattern, the method flow of the embodiment that air-conditioner controls is comprised the steps:
Step 301: air-conditioning is started shooting, controls compressor operating.
Air-conditioning start after, by set according to user or acquiescence operational mode and operational factor, according to predetermined control program control compressor operating.
Step 302: judge whether air-conditioning enters room temperature PID and control.If so, step 304 is performed; If not, step 303 is performed.
In airconditioning control process, by according to whether entering room temperature PID to the control of compressor control to perform different control, specifically, whether room temperature PID is entered to compressor and controls to be the necessary condition determining whether to compensate indoor temperature.
Wherein, room temperature PID to control to refer to according to the temperature difference of current indoor temperature and indoor objects temperature as control objectives, performs a kind of control procedure that PID controls.And, after air-conditioning start, and non-immediate enters room temperature PID control, generally just enter PID after the certain value that has a narrow range of temperature between current indoor temperature and indoor objects temperature to control, therefore, can judge whether air-conditioner enters room temperature PID and control according to whether the temperature difference between current indoor temperature and indoor objects temperature is little to certain value.In addition, other can also to be adopted in prior art to judge, and whether air-conditioner enters the method that room temperature PID controls and judges.
Step 303: if step 302 judges that air-conditioner does not also enter room temperature PID and controls, conveniently control method controls compressor.
Also namely, control if air-conditioner does not also enter room temperature PID, then do not perform the process that indoor temperature compensates, but conveniently control method controls compressor.Wherein, conventional control methods refers to the control method of existing transducer air conditioning.Such as, the control method of existing air-conditioner is: the temperature difference between indoor temperature and indoor objects temperature is greater than when setting the temperature difference, controls compressor high frequency and runs, until the temperature difference of indoor temperature and indoor objects temperature is not more than the setting temperature difference.So, when compressor operating time does not also reach setting running time, if compressor wants high frequency to run in conventional control methods, then maintenance high frequency running status, make indoor temperature can approach indoor objects temperature fast, rapidly for user provides an indoor environment be comparatively suitable for.
Conveniently control method controls in compressor operating process, still constantly performs and judges whether air-conditioner enters the process of room temperature PID control.
Step 304: if step 302 judges that air-conditioner enters room temperature PID and controls, will compensate indoor temperature, then, utilizes the indoor temperature after compensating to calculate the compressor frequency of room temperature PID control.
Specifically, when judging that air-conditioner enters room temperature PID control, obtaining the current indoor temperature that indoor temperature transmitter detects, as the first indoor temperature, calculating the difference of the first indoor temperature and setting compensation temperature, as the second indoor temperature.
Wherein, setting compensation temperature is the temperature value prestoring, can call at any time, is also obtained by special experiment condition and the test of special test means and be written to the numerical value in accumulator for air conditioner before air-conditioning dispatches from the factory, by air-conditioning research staff.When reaching setting running time when the compressor is operating, meet condition indoor temperature being compensated to control, then obtain current indoor temperature detected by indoor temperature transmitter, using this current indoor temperature as the first indoor temperature.Then, obtain setting compensation temperature, calculate the difference of the first indoor temperature and setting compensation temperature, using this difference as the second indoor temperature.Then, step 105 is performed.
Step 305: the temperature difference calculating the second indoor temperature and indoor objects temperature, obtains the indoor temperature difference, carries out room temperature PID computing according to the indoor temperature difference, obtains compressor first object frequency.
Wherein, carry out room temperature PID computing according to the indoor temperature difference, obtain and can adopt prior art to realize to the concrete grammar of the target frequency that compressor controls.But unlike the prior art, the indoor temperature calculating the indoor temperature difference is not the temperature that indoor temperature transmitter detects, but the second indoor temperature obtained after temperature-compensating has been carried out to the temperature detected.
Step 306: whether the second indoor temperature that determining step 304 obtains is less than comfort temperature.If so, the dual PID performing step 308 and subsequent step controls; Otherwise the room temperature PID performing step 307 controls.
This step 306 can be carried out with step 304 and step 305 simultaneously, is divided into that to describe sequentially be only control procedure in order to clearly state this embodiment at this.After step 304 obtains the second indoor temperature, the comfort temperature of the second indoor temperature and setting is made comparisons, and judge whether the second indoor temperature is less than comfort temperature.Wherein, comfort temperature can be a default setting temperature of air-conditioning when dispatching from the factory, and also can be selected voluntarily by user and arrange design temperature.If by user's sets itself, air-conditioning can provide a reference temperature value, for reference.Such as, advise this comfort temperature to be set as 27 DEG C.
Step 307: if the second indoor temperature is not less than comfort temperature, performs room temperature PID and controls, according to first object FREQUENCY CONTROL compressor.
If step 306 judges that the second indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, then perform room temperature PID and control, according to first object FREQUENCY CONTROL compressor, make indoor temperature fast cooling to indoor objects temperature.
Step 308: if the second indoor temperature is less than comfort temperature, performs dual PID and controls.
If step 306 judges that indoor temperature is less than comfort temperature, cause body sense uncomfortable for avoiding the too fast decline of temperature, perform dual PID to control, so that adjustment compressor operating frequency in time, make evaporator coil temperature can be stabilized to coil pipe target temperature, to adjust air conditioning exhausting temperature, reach cool and not cold comfortable air-out effect.The process that concrete dual PID controls is see the description of step 309 and step 310 below.
Step 309: the coil temperature detecting evaporimeter, carries out coiling warm PID arithmetic according to the coil pipe temperature difference, obtains the second target frequency.
The detection of the coil temperature of evaporimeter detects by set temperature sensor on evaporator coil.After detecting coil temperature, calculate the temperature difference between coil temperature and the coil pipe target temperature of setting, using this temperature difference as the coil pipe temperature difference.Wherein, coil pipe target temperature can be a default setting temperature of convertible frequency air-conditioner when dispatching from the factory, and can certainly be selected voluntarily by user and arrange design temperature.If by user's sets itself, because user is not very clear and definite for the concept of coil temperature and the performance indications of representative thereof, preferably provide a reference temperature value by convertible frequency air-conditioner, for reference selected.Such as, advise this coil pipe target temperature to be set as 14 DEG C.Then, carry out coiling warm PID arithmetic according to the coil pipe temperature difference, obtain the target frequency that compressor is controlled, and this target frequency is defined as the second target frequency.Coil warm PID arithmetic and obtain the method that can obtain compressor target frequency to the method for the target frequency that compressor controls with reference to room temperature PID computing of the prior art.Wherein, the original frequency coiling warm PID arithmetic can be the original frequency of a setting.Preferably, the original frequency coiling warm PID arithmetic is that step 306 judges that indoor temperature is less than comfort temperature, performs the current operation frequency of compressor when dual PID controls.And this current operation frequency is at least a running frequency after compressor operating a period of time (as 3min).
Step 310: the smaller value in the second target frequency that the first object frequency calculated according to step 305 and step 309 calculate controls compressor.
When indoor temperature is less than comfort temperature, warm PID arithmetic is coiled in coil pipe target temperature execution according to coil temperature and setting, and according to room temperature PID computing export first object frequency and coil warm PID arithmetic export the second target frequency in smaller value control compressor operating, while refrigeration cool-down, adjust coil temperature, coil temperature can be approached to coil pipe target temperature.
As previously indicated, when air-conditioner running refrigerating pattern, the temperature that indoor temperature transmitter detects is higher than the temperature in user's main activities space.If the temperature still detected according to indoor temperature transmitter participates in PID arithmetic as indoor temperature, indoor temperature difference during PID arithmetic is bigger than normal, the compressor target frequency calculated is higher, controls compressor and runs according to higher target frequency, cause air-conditioner energy consumption bigger than normal.And adopt the method for this embodiment, first the indoor temperature of detection is deducted a compensation temperature, obtain the second indoor temperature being less than the current indoor temperature of detection, and this second indoor temperature reflects the temperature in user's main activities space more realistically.When the second indoor temperature utilizing this less than normal participates in PID arithmetic, can obtain less compressor target frequency, the target frequency utilizing this less controls compressor operating, reduces energy consumption.And, because this second indoor temperature reflects the temperature in user's main activities space more realistically, thus, the indoor temperature after regulating also can be made more close to indoor design temperature, and there will not be the problem of overshoot, while satisfied temperature regulates comfortableness, reduce air-conditioner energy consumption.Meanwhile, by arranging comfort temperature, the second indoor temperature and comfort temperature being made comparisons, when indoor temperature is higher, adopts room temperature PID to control compressor operating, make indoor temperature fast cooling and approach indoor objects temperature.When indoor temperature is less than comfort temperature, adopt room temperature PID to control to control with the dual PID that controls of the warm PID of dish: just to enter coil warm PID control time, coil warm PID to control to play a major role, while cooling, preferentially make coil temperature rise to approach coil pipe target temperature; And when coil temperature is close to coil pipe target temperature, room temperature PID plays a major role, make indoor temperature be stabilized in indoor objects temperature, avoid causing because of room temperature overshoot air-conditioning to shut down the generation of phenomenon.Thus, in whole refrigeration control process, the basis approaching indoor objects temperature making indoor temperature making coil temperature approach coil pipe design temperature, both having met room temperature and having regulated, having realized again the comfortableness of air conditioning exhausting, reach cool and not cold refrigeration.
It should be noted that, in the process performing dual PID control, still constantly compare the size of the second indoor temperature and comfort temperature.Once indoor temperature is not less than comfort temperature, then exits dual PID control procedure, be transferred to room temperature PID control procedure.
And, in whole control procedure, not compressor runs the compensation just performing indoor temperature at the beginning, but first keep compressor conveniently control strategy operation, ensure that indoor temperature can conveniently control mode, rapidly near indoor objects temperature, the speed of indoor temperature comfort conditioning can not be affected.
As preferred embodiment, when indoor temperature is not less than comfort temperature and the difference of indoor temperature and comfort temperature is greater than the difference of setting, then exit dual PID control procedure, be transferred to room temperature PID control procedure.By the difference that choose reasonable sets, such as, be set as 1 DEG C, can guarantee that coil temperature is not less than coil pipe target temperature, ensure out cool and not cold comfortableness.
And, run in control procedure, if the non-wind speed setting of user at the air conditioner refrigerating of this embodiment, then control air-conditioning draught fan to run according to highest wind velocity, because under same refrigerating capacity, the leaving air temp of high wind speed is higher than the leaving air temp of low wind speed, guarantees that leaving air temp can not be too low further.And if the wind speed that user sets detected, then control blower fan according to setting wind speed run.
In the above-described embodiments, performing how many temperature-compensatings to indoor temperature, is concern the key factor that air-conditioner controls comfortableness and energy saving.Also namely, selecting of setting compensation temperature is key factor wherein.
As preferred embodiment, the setting compensation temperature prestore in air-conditioning, called at any time is a compensation temperature corresponding with indoor objects temperature and outdoor temperature.Determine setting compensation temperature based on indoor objects temperature and outdoor temperature, can realize the Reasonable Regulation And Control of function of temperature compensation control in degree of compensation based on operation of air conditioner load, reach the equilibrium of Thermal comfort adjustment and low energy consumption energy saving.
And what prestore in air-conditioning is indoor objects temperature range, outdoor temperature scope and the multiple compensation temperatures corresponding with indoor objects temperature range and outdoor temperature scope.When performing function of temperature compensation control in operation of air conditioner process, setting compensation temperature is called by following process:
Current indoor target temperature and the indoor objects temperature range prestored are made comparisons, judges the indoor objects temperature range belonging to current indoor target temperature; Current outdoor temperature and the outdoor temperature scope prestored are made comparisons, judges the outdoor temperature scope belonging to current outdoor temperature; According to searching in that prestore, corresponding with indoor objects temperature range and outdoor temperature scope multiple compensation temperatures with the indoor objects temperature range belonging to current indoor target temperature and the corresponding compensation temperature of the outdoor temperature scope belonging to current outdoor temperature as setting compensation temperature, and call.
The above-mentioned mode with temperature range is determined and is called setting compensation temperature, and data processing amount is little, and control procedure is simple, is more conducive to carrying out controlling in time, effectively to air-conditioner, improves the speed that Thermal comfort regulates, and reduces operation energy consumption.
Above embodiment only in order to technical scheme of the present invention to be described, but not is limited; Although with reference to previous embodiment to invention has been detailed description, for the person of ordinary skill of the art, still can modify to the technical scheme described in previous embodiment, or equivalent replacement is carried out to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the present invention's technical scheme required for protection.
