Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention Specific embodiment be described in detail.
Obviously, embodiment described is a part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention In embodiment, the every other embodiment that those skilled in the art obtain without making creative work, all Belong to the scope of protection of the invention.
In order to make it easy to understand, in the present invention, need to wherein the technical issues of be described in detail.
Frequency unit is determined due to that can not adjust compressor operating frequency in fixed frequency air conditioner at present, when refrigerating operaton, works as interior When environment temperature is equal to or less than target set temperature, it is assumed that meeting up to warm halt condition, air-conditioning system is directly shut down;In During shutdown, since indoor environment temperature is lower than outdoor environment temperature, indoor environment temperature can gradually go up, if going back up to refrigeration Temperature threshold, then air-conditioning system can directly be switched on, and carry out refrigerating operaton;Indoor environment temperature can thus be controlled in target Between set temperature and cryogenic temperature threshold value.
But air-conditioning generally freezes during the broiling summer, indoor environment temperature and outdoor environment temperature difference at this time It is very big;In this way, after air-conditioning system is shut down up to temperature, since outdoor environment temperature is much higher than indoor environment temperature at this time, indoor and outdoor Heat exchange is rapid, and indoor environment temperature can be made to go back up to cryogenic temperature threshold value rapidly;Air-conditioning system is directly switched at this time, carries out Indoor environment temperature is dropped rapidly to target set temperature by refrigerating operaton, and then air-conditioning system is shut down up to temperature;Hereafter indoor ring Border temperature is going back up to rapidly cryogenic temperature threshold value.In this way, indoor environment temperature constantly rises rapidly, following of declining rapidly Ring, the rapidly variation of this indoor environment temperature, will lead to user experience and becomes very poor.
In addition, it is necessary to which explanation, in order to protect compressor, can be provided with the compressor shutdown time in general air-conditioning system Protection and the protection of compressor available machine time.In above situation, if indoor environment temperature gos up during air-conditioning system is shut down up to temperature Excessive velocities, it may appear that in the case where compressor shutdown guardtime not yet releases, indoor environment temperature has gone back up to refrigeration Temperature threshold, air-conditioning system will continue to carry out compressor shutdown guardtime at this time, until the protection releases;Such case Under, after protection releases, indoor environment temperature has exceeded cryogenic temperature threshold value.The fluctuation range that this allows for indoor environment temperature is super The limitation of cryogenic temperature threshold value out, the big situation of this temperature fluctuation can further result in user experience variation.
It should also be noted that, for fixed frequency air conditioner, in the situation that the operating status of outer blower and compressor is constant Under, the wind speed of inner blower is faster (wind file is higher), and the heat exchange of air conditioner indoor unit and indoor environment is faster, indoor environment temperature Decline also faster;Conversely, the wind speed of inner blower is slower, the decline of indoor environment temperature is also slower;In special circumstances, if The wind speed of inner blower is very slow, then the heat that indoor unit is taken away from indoor environment is also fewer, if outdoor environment is passed to room at this time The heat of interior environment is equal with the heat that indoor unit is taken away from indoor environment, then indoor environment temperature can reach equilibrium state, no Change again.
The embodiment of the present disclosure provides a kind of fixed frequency air conditioner control method, this method can by fixed frequency air conditioner control device Lai It executes, which can integrate in the electronic equipments such as air-conditioning.As shown in Figure 1, it is according to of the invention real Apply the flow chart of the fixed frequency air conditioner control method of example;Wherein, the fixed frequency air conditioner control method, comprising:
Step 10, after power-on of air conditioner, target set temperature and real-time indoor environment temperature are obtained;
Wherein, the target set temperature can be pre-set in air conditioner, is also possible to user and passes through remote controler The settings such as mobile phone;The storage of the target set temperature and reading manner can be adjusted, herein no longer according to actual needs It repeats.
Wherein, the indoor environment temperature can be is obtained by the temperature sensor measurement in air conditioner, is also possible to It is obtained after carrying out temperature-compensating to measured value after measurement;It can also such as calculate and obtain by other means.It should be noted that Indoor environment temperature described herein is real time temperature.
Step 20, according to the indoor environment temperature and the target set temperature, judge the indoor environment temperature and Whether the differential temperature of the target set temperature is greater than first threshold;
In this step, the setting of first threshold is to distinguish whether the indoor environment temperature has been approached the target Set temperature.
Wherein, the differential temperature of the indoor environment temperature and the target set temperature refers to the indoor environment temperature Degree subtracts the value of the target set temperature, described when the indoor environment temperature is less than the target set temperature Differential temperature is negative value.
Optionally, the first threshold is 2 DEG C.
Step 30, if more than the first threshold, then the compressor and the outer blower is opened, the inner blower is controlled With the operation of high wind file;
The differential temperature is greater than the first threshold, it is meant that the indoor environment temperature is reduced to the goal-setting There are also a distances for temperature, herein with the operation of high wind file, can increase the cooling rate of indoor environment temperature, in order to the room Interior environment temperature is quickly reduced near the target set temperature.
Step 40, the runing time of the compressor is recorded, and judges the differential temperature;
In the application, the indoor environment temperature obtains in real time, and in other words the differential temperature is to calculate in real time Out.
Wherein, the runing time of compressor since compressor operation after timing, when compressor shutdown until;Compressor After shutdown, runing time is reset, the reclocking again after booting next time.
It step 50, will be described when the differential temperature is more than or equal to the third threshold value and is less than or equal to second threshold Inner blower is switched to low wind file, and the second threshold is less than the first threshold;
The setting of first threshold is to distinguish whether the indoor environment temperature has been approached the target set temperature; The second threshold is less than the first threshold, then the second threshold can be used for further discriminating between the indoor environment temperature Whether degree has been approached the target set temperature;The differential temperature is less than or equal to the second threshold, it is meant that the interior The inner blower is switched to low wind file at this time very close to the target set temperature by environment temperature, can reduce indoor ring The cooling rate of border temperature avoids the rapid decrease of indoor environment temperature.
Optionally, the second threshold is 1 DEG C.
Step 60, it is less than the third threshold value in the differential temperature and the runing time is greater than the first preset time Afterwards, the compressor, the outer fan parking are controlled.
Wherein, first preset time be compressor the power-on protection time, also as compressor booting after need through Crossing after the first preset time can just shut down, and cause to damage to compressor to avoid frequent shutdown.
Optionally, first preset time is 3~8min.
The third threshold value, if the differential temperature is less than the third threshold value, to show described up to warm shutdown threshold Air-conditioning has reached shutdown temperature, therefore controls the compressor and the outer fan parking.
Optionally, the third threshold value is negative value.In this way, the lower limit of indoor environment temperature variation is increased, so that Indoor environment temperature fluctuates near target set temperature, increases the comfort of temperature and the experience sense of client.
Optionally, the third threshold value is -1 DEG C.In addition, the second threshold is 1 DEG C., indoor ring can be kept in this way Border temperature and target set temperature change within the scope of 1 degree, avoid the big ups and downs of indoor environment temperature.
Pass through step 10-60, after the indoor environment temperature is reduced to target set temperature attachment, inner blower low wind file Operation, to delay the cooling rate of indoor environment temperature, avoids the rapid decrease of indoor environment temperature;In addition, then with For indoor environment temperature towards the close of target set temperature, the heat that outdoor environment is penetrated to indoor environment is also getting faster (temperature Difference is higher, and heat transmission is faster), in this way, if the indoor and outdoor surroundings temperature difference is higher, the inner blower of low wind file operation, so that indoor After environment temperature is reduced to certain temperature (temperature is not yet triggered shuts down up to temperature), can indoor unit be taken away from indoor environment The heat that heat and outdoor environment are passed to indoor environment no longer declines so that indoor environment temperature reaches equilibrium state, if indoor The external environment temperature difference is lower, then can finally trigger shutting down up to temperature for air-conditioning system, but during shutting down at this time, indoor environment temperature Go up slower;In this way, the higher situation of the indoor and outdoor surroundings temperature difference can be limited and (be screened out), avoid triggering up to temperature It shuts down, so that indoor environment temperature recovery is slow after shutting down up to temperature;This way it is possible to avoid it is continuous indoor environment temperature occur The case where ground rises rapidly and declines circulation, promotes the experience sense of user, and the rise of indoor environment temperature is slow, can also keep away Exempt from the compressor shutdown guard period shut down up to temperature, indoor environment temperature is gone back up on cryogenic temperature threshold value, thus by indoor The fluctuation range of environment temperature is limited under cryogenic temperature threshold value, prevents the big situation of temperature fluctuation, is further promoted User experience.
Optionally, as shown in Fig. 2, after the step 40, comprising:
It step 70, will be described when the differential temperature is greater than the second threshold and is less than or equal to the first threshold Inner blower is switched to middle wind file.
In this way, three value intervals are arranged, indoor environment temperature more leans on by first threshold, second threshold, third threshold value Close-target set temperature, differential temperature are smaller;With the reduction of differential temperature, the corresponding inner blower wind file of three value intervals It gradually becomes smaller, that is to say that the wind speed of inner blower is smaller, the decrease speed of indoor environment temperature is also smaller and smaller, thus according to the temperature difference Size actively adjusts inner blower revolving speed, forms the smooth adjustment to indoor environment temperature.
In addition, by indoor environment temperature and the differential temperature of target set temperature with inner blower wind speed corresponding, differential temperature It is bigger, it is more to illustrate that needs are adjusted, to need inner blower wind speed to run with high wind file, to reduce differential temperature as far as possible;When When differential temperature is met certain condition, inner blower wind file is gradually reduced, to reduce control of the indoor fan to indoor environment temperature, It prevents from adjusting and overshoot.
Optionally, the low wind file include the inner blower lowest gear and the gear adjacent with the lowest gear, Or the lowest gear including the inner blower.
Optionally, the high wind file includes the highest gear and/or the shelves adjacent with the highest gear of the inner blower Position, or the highest gear including the inner blower.
Optionally, the middle wind file includes other gears in addition to highest gear and lowest gear of the inner blower.
Optionally, the low wind file, the high wind file, the middle wind file are not intersected.In this way, being not in certain of inner blower A gear belongs to the low wind file, the high wind file, two situations in the middle wind file simultaneously, and inner blower operation is avoided to lose Accidentally.
Wherein, for the ease of understanding low wind file, middle wind file, high wind file, herein respectively with three wind files (from low to high Be followed successively by first grade, second gear, third gear) and five wind files (be followed successively by first grade, second gear, third gear, fourth speed from low to high And fifth speed) for be described in detail.
If inner blower is three wind files, the high wind file includes third gear, and the middle wind file includes second gear, the low wind Shelves include first grade;
If inner blower is five wind files, the high wind file includes fifth speed or simultaneously includes fourth speed, the low wind file It including first grade or simultaneously include second gear, the middle wind file includes third gear or simultaneously includes second gear (in low wind In the case that shelves do not include second gear), or simultaneously include fourth speed (in the case where high wind file does not include fourth speed).
Optionally, the low wind file may be that the current wind file of inner blower is turned down a gear, wherein the current shelves Position is the preset gear of the inner blower.
Optionally, the high wind file may be that a gear is turned up in the current wind file of inner blower, and the current gear is The preset gear of the inner blower.
Optionally, the middle wind file may be the default wind file of inner blower.
Above-mentioned default wind file can pass through the setting such as remote controler, mobile phone for user, or true by actual conditions It is fixed.
In this way, can be adjusted according to wind file of the default wind file to inner blower, flexibility is higher, can more meet user's Use habit improves user experience.
Optionally, as shown in figure 3, after the step 60, further includes:
Step 80, the downtime of the compressor is recorded, and judges the differential temperature;
In the application, the indoor environment temperature obtains in real time, and in other words the differential temperature is to calculate in real time Out.
Wherein, timing the downtime of compressor is after compressor shutdown, until when compressor is switched on;Compressor After booting, downtime is reset, the reclocking again after shutting down next time.
Step 90, it is greater than the second preset time in the downtime and the differential temperature is greater than the second threshold When, the compressor and the outer blower are opened, the inner blower is controlled and is run with middle wind file;And return to the step 40.
Wherein, second preset time be compressor the stoppage protection time, also as needed after compressor shutdown through Crossing after the second preset time can just be switched on, and cause to damage to compressor to avoid frequent booting.
Optionally, second preset time is 4~8min.
In this way, if indoor environment temperature goes back up to second threshold, be switched on after being shut down up to temperature and carry out refrigerating operaton, from And continue smoothly to cool down, until being shut down up to temperature;The circulation up to temperature shutdown and booting refrigeration is so carried out, thus by indoor ring Border temperature limiting is between shutdown temperature and turn-on temperature.
Optionally, as shown in figure 4, after the step 40, further includes:
Step 100, it is greater than the first threshold in the differential temperature and the runing time is greater than the first preset time Afterwards, the inner blower is switched to setting wind file.
Wherein, the setting wind file is user by the setting such as remote controler, is also possible to be arranged according to actual needs, or Person is debugged by engineering to be arranged.
When the differential temperature is greater than the first threshold, inner blower is run with high wind file, is cooled down as early as possible, but After the runing time is greater than the first preset time, differential temperature is still greater than first threshold, shows to run simultaneously by high wind file It has not been able to for indoor environment temperature to be reduced to suitable position (being also likely to be to go up again after reducing), at this point, being further continued for keeping high The effect of wind file has not had too big meaning (mean can not fast cooling), can be dropped instead due to high wind file bring noise etc. The experience sense of low user;Therefore inner blower is switched to setting wind file, to improve the usage experience of client.
Optionally, in inner blower handoff procedure, high wind file is switched to bottom wind file, can directly switch when needing to switch; When low wind file is switched to high wind file, inner blower is needed, more than third preset time, then to switch again in low wind file runing time To high wind file.
In this way, high wind file turns no-delay when low wind file, low wind file turns to need to meet wind file switching minimum operation when high wind file Time (third preset time), it is ensured that indoor fan is not in frequent bounce situation.
In addition, wind speed changes, system operation will affect, when the operation of high wind file, air quantity is big, and indoor energy exchange is larger, When meeting wind speed switching condition, wind speed is not reduced immediately, temperature difference may be directly entered up to temperature and shut down range, and Da Wen is caused to stop Machine, so needing to be immediately switched to low one grade of wind file at this time, minimum can be reduced to low wind file;When needing to run toward high wind file, Need to meet third preset time because low wind file is switched to high wind file, wind speed cannot switch in each wind file without limitation, Ke Yibao Card system is stablized.
Optionally, the third preset time is 1~3min.
Optionally, in the step 100, if the wind file before inner blower switching is lower than the setting wind file, in institute After inner blower is stated with the wind file operation third preset time before switching, the inner blower is switched to the setting wind file. So that it is guaranteed that indoor fan is not in frequent bounce situation.
