Detailed Description
In order to make the aforementioned objects, technical solutions and advantages of the present invention more comprehensible, the present invention is described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only some of the embodiments constituting the present invention, and are not intended to limit the present invention, and the embodiments and features of the embodiments may be combined with each other without conflict.
For convenience of description, the invention aims to realize the fresh air control of the fresh air conditioner by setting three fresh air gears, namely a low fresh air gear, a medium fresh air gear and a high fresh air gear, so that the fresh air volume of the fresh air conditioner is matched with the fresh air gear at the current moment by adjusting and setting different gears. It should also be understood that the above-described arrangements are only intended to better explain the present invention to those skilled in the art and should not be taken as limiting the present invention. For example, the fresh air conditioner can also set more fresh air gears according to specific needs, and is not limited to the setting of the three fresh air gears, or the fresh air conditioner can not set the fresh air gears, but directly meets the fresh air adjusting needs through stepless speed regulation.
In the invention, the rotation speed S of the fresh air motor (hereinafter referred to as "fresh air rotation speed S") can satisfy the setting of the fresh air gear and also have a stepless speed regulation function, or in other words, the fresh air rotation speed S corresponding to each fresh air gear can also have a certain dynamic speed regulation interval. For example, if the rated rotation speeds of the fresh air motors corresponding to the low, medium and high fresh air gears are set to 700r, 1200r and 1700r, respectively, the dynamic speed regulation interval of the fresh air rotation speed S in the high wind gear can be set to (1200r and 1700r), and the dynamic speed regulation interval of the fresh air rotation speed S in the medium wind gear can be set to (700r and 1200r), for example. Wherein, corresponding to the rated rotating speed of the fresh air motor, the fresh air volume M corresponding to the low, medium and high fresh air gears is respectively 10M3/h、30m3/h、60m3And h, the fresh air quantity M is increased and decreased along with the increase and decrease of the fresh air rotating speed S.
All the embodiments of the present invention will be specifically explained below mainly by setting three fresh air gears, i.e., low, medium and high, in the fresh air conditioner.
Example 1
As shown in fig. 1 to 3, the present invention provides a fresh air control method, which includes the following steps:
s1: receiving a fresh air starting signal in a refrigerating or heating mode;
s2: according to the outdoor ambient temperature TOuter ringDetermining the upper limit of the new air gear FUpper limit of；
S3: according to the upper limit of the fresh air gear FUpper limit ofSetting a gear F for fresh airIs provided withCorrection is carried out to determine a fresh air starting gear FOpener；
S4: air conditioner starts gear F according to new trendOpenerAnd starting the fresh air fan.
Specifically, the fresh air is set to a gear FIs provided withThe setting timing may be set by the user at the beginning of the opening of the fresh air function, or may be changed by the user during the operation of the fresh air function (corresponding to the fresh air switching signal in step S6 below). Certainly, if the user does not perform the F-pair function at the beginning of the opening of the fresh air function at this timeIs provided withThe air conditioner can automatically set the latest fresh air running gear F as the current fresh air setting gear F by defaultIs provided withOr continue to automatically continue using last FIs provided withIn the invention, the gear F is not set for the fresh airIs provided withThe specific treatment of (3) is not particularly limited.
Taking the cooling mode as an example, the cooling performance of the air conditioner follows TOuter ringIs increased and decreased, and the fresh air load Q is changed along with TOuter ringIs increased. In the whole process of operation of the air conditioner, when the fresh air function is started, in order to avoid that the refrigeration performance of the air conditioner is affected by overlarge fresh air load Q, the fresh air volume M can be properly adjusted and reduced according to a fresh air load formula Q (h1-h2)/Vn, so that the refrigeration performance of the air conditioner is ensured by properly reducing the fresh air load Q. Still taking the background art as an example, in the same scene, if the fresh air volume M is reduced to 20M3At/h, the fresh air load Q can be halved, thereby ensuring that the refrigeration performance of the air conditioner can be matched with the outdoor environment temperature T when necessaryOuter ringIs maintained or even elevated.
By the fresh air control method, the fresh air is controlled according to the outdoor environment temperature TOuter ringTo the upper limit of the new wind gear FUpper limit ofThe setting of the division is carried out, and then the fresh air starting gear FOpenerWill be composed of FUpper limit of、FIs provided withThe two values can be determined only after comprehensive judgment. When the air conditioner operates in a refrigerating or heating mode, the fresh air fan is started, so that the fresh air requirement under the subjective intention of a user is fully considered, and the outdoor environment temperature T is also consideredOuter ringThe influence that also is the biggest fresh air volume to air conditioner refrigeration or heating performance compares in prior art, has promoted the minimum comfortable guarantee of air conditioner on temperature regulation, is favorable to whole journey and diversified travelling comfort that guarantees the air conditioner operation in-process and experiences. Based on the above inventive concept, the logic of the present invention is substantially the same for the heating mode and the cooling mode, and the present invention is not described in detail herein.
As one of the preferred embodiments of the present invention, step S1 includes the following specific operation steps:
s11: receiving a fresh air starting signal in a refrigerating or heating mode;
s12: judging whether a fresh air starting signal is received at the same time when the refrigeration or heating mode is started;
s13: if yes, go to step S2; if not, the air conditioner sets a gear F according to the fresh airIs provided withAnd starting the fresh air fan.
Specifically, still taking the refrigeration mode as an example, when the refrigeration mode is started, the air conditioner needs to enter the rapid cooling stage urgently, at this moment, the user has a high requirement on the refrigeration performance of the air conditioner, and the simultaneous starting of the refrigeration mode and the fresh air function will undoubtedly need to promote the air conditioning performance urgently, resulting in load crowding to a greater extent. The steps S11-S13 may be optimally set according to specific needs, for example, when the maximum operating load of the air conditioner is relatively larger than the installation and use environment of the air conditioner, the opening of the fresh air function may be limited only in the rapid cooling stage of the air conditioner to form relatively obvious load crowding for the air conditioning performance, and at this time, the steps S11-S13 are preferably set; on the contrary, the relatively obvious load occupation may not be limited to the rapid cooling stage of the air conditioner, and in this case, the steps S11-S13 are not required. Therefore, the air conditioner fully considers the influence of the performance of the air conditioner and the installation and use environment on the adjustment and control of the comfort, and the comfort experience of the air conditioner in the whole running process is better.
In addition, regarding the expression of the word "simultaneously" in step S12, it can be understood by those skilled in the art herein that it may refer to: the fresh air opening signal is received within a short interval duration at the time of the opening of the cooling or heating mode, and the short interval duration may be any one of 1 minute, 5 minutes and 10 minutes, for example.
Preferably, after step S4, the method further comprises the steps of:
s6: setting gear F for fresh air received in the operation process of fresh air fanIs provided withAnd/or outdoor ambient temperature TOuter ringThe fresh air switching signal;
s7: return is made to step S2.
Specifically, as described above, the fresh air setting gear FIs provided withOr the setting can be changed by the user in the running process of the fresh air function, for example, the medium wind gear is changed into the high wind gear, so that the fresh air requirement under the user's subjective intention can be more fully embodied in time. In fact, whether based on the outdoor ambient temperature TOuter ringIs also based on the setting of the new air gear FIs provided withThe user initiatively changes, and the new trend operational mode all probably takes place to switch, just compare in the latter, the former must have certain range of variation, otherwise the new trend switching signal is difficult to be triggered.
When the invention further comprises steps S6-S7, the gear F is started for the fresh airOpenerThe re-determination of the new air gear position upper limit F can be more timely reflected by the new air gear position upper limit FUpper limit ofBased on the outdoor ambient temperature TOuter ringThe latest change of (2) and then to the regulation of new trend operational mode, on the basis that accords with user's use custom, the air conditioner is experienced and can be further improved at the travelling comfort of whole operation in-process.
Preferably, step S2 includes the following specific operation steps:
s21: in the cooling mode, the outdoor environment temperature T is judgedOuter ringWhether the temperature is greater than or equal to a first preset temperature T1(ii) a Or in the heating mode, the outdoor environment temperature T is judgedOuter ringWhether or not less than or equal to a second preset temperature T2；
S22: if yes, go to step S23; if not, go to step S24;
s23: determining the upper limit of the new air gear FUpper limit ofA middle wind gear;
s24: determining the upper limit of the new air gear FUpper limit ofIs a high wind gear.
Specifically, still take the cooling mode as an example, when the outdoor environment temperature TOuter ringHas reached a first preset temperature T1In the meantime, the refrigerating performance of the air conditioner is obviously reduced, the fresh air load Q is obviously increased, and at the moment, if the fresh air is set to be in a gear FIs provided withIf the wind level is high, the operation of the fresh air function is likely to fail to ensure that the fresh air function cannot generate obvious load crowding on the air conditioning performance, and further the minimum comfort guarantee of the air conditioner on temperature regulation cannot be ensured, at this time, although the guarantee can be completed by means of the step S23, the step S23 can appropriately reduce the fresh air demand of the user; on the contrary, the minimum comfort guarantee of the air conditioner in the temperature adjustment can be ensured, and the step S23 is not required. Therefore, on the basis of improving the minimum comfortable guarantee of the air conditioner, the fresh air demand under the subjective intention of the user is fully considered to the maximum extent.
Preferably, the first preset temperature T1The temperature was 43 ℃.
Specifically, to most air conditioners that circulate on the market at present, 43 ℃'s settlement has great universality, and it is on the basis of the minimum comfortable guarantee that the promotion air conditioner is based on temperature regulation, is favorable to fully taking into account the new trend demand under the subjective wish of user to the at utmost, and then whole journey and diversified comfort that guarantee the air conditioner under the refrigeration mode experience better. Similarly, the second predetermined temperature T2For example, it may be set to-10 ℃.
Preferably, step S4 includes the following four operation results:
s41: fresh air setting gear FIs provided withWhen the wind gear is high, the fresh air fan is started according to the wind gear;
s41': fresh air setting gear FIs provided withWhen the wind gear is high, the fresh air fan is started according to the high wind gear;
s42: fresh air setting gear FIs provided withWhen the wind gear is the middle wind gear, the fresh air fan is started according to the middle wind gear;
s43: fresh air setting gear FIs provided withAnd when the wind gear is low, the fresh air fan is started according to the low wind gear.
As one example of the present invention, when setting the upper limit of the fresh air gear FUpper limit ofAt the lowest, medium gear, step S4 has and can only include the above four operational results. Here, the operation result S41 corresponds to step S23, and the operation result S41' corresponds to step S24. The four operation results can greatly improve the lowest comfort guarantee of the air conditioner based on temperature regulation.
Specifically, when the new air gear upper limit FUpper limit ofWhen the lowest wind gear is the middle wind gear, namely the upper limit of the fresh air gear FUpper limit ofOnly two results, namely, a middle gear and a high gear, can be obtained, namely, corresponding to the step S2, and only two operation results corresponding to the steps S23 and S24 can be obtained. Because of the difference between steps S23 and S24, step S4 is at "New wind Shift position FIs provided withUnder the same conditions of "high gear", two completely different operation results of S41 and S41' will be produced; the operation results S42 and S43 are both obtained as a general operation result, regardless of whether the steps S23 and S24 are different.
More specifically, the upper limit of the new air gear is FUpper limit ofIn combination with the new air setting of the gear FIs provided withAfter the operation of step S3, corresponding to step S4, the three combinations of (a) and (b) can only generate four operation results in total. I.e. corresponding to the upper limit of the new air gear FUpper limit ofThe minimum medium windshield setting is equivalent to raising the correction threshold of step S3, i.e. regardless of the outdoor ambient temperature TOuter ringHow to change all avoid setting a gear F for the fresh airIs provided withThe excessive correction of the air conditioner is another layer of ensuring the minimum fresh air requirement of the user, and the minimum comfort guarantee of the air conditioner is improved.
Preferably, in the cooling mode, corresponding to the operation result S41' and/or S42, the method further includes the following specific operation steps:
s51: judging the indoor temperature TAWhether it is stable;
s52: if yes, judging the indoor temperature TAWhether less than or equal to user-set temperature Ts(ii) a If not, returning to the step S51;
s53: if yes, go to step S55; if not, judging the indoor temperature TAWhether or not less than or equal to a third preset temperature T3；
S54: if yes, go to step S55; if not, go to step S56;
s55: the fresh air rotating speed S starts a gear F according to the fresh airOpenerThe rated rotating speed of the motor is kept unchanged;
s56: the fresh air rotating speed S is reduced according to a first preset speed, and the fresh air rotating speed S stops reducing and keeps the current rotating speed to operate after a first preset condition is triggered.
Specifically, as one example of the present invention, step S51 may adopt the following determination manner: when indoor temperature TAIs less than or equal to a first fluctuation threshold value within a first preset time length, the indoor temperature T is judgedAStabilizing; on the contrary, the indoor temperature TAIf the measurement is unstable, the above determination is continuously maintained. The first preset time period may be set to 10 minutes, and the first fluctuation threshold may be set to 0.5 ℃.
In the invention, the upper limit F of the fresh air gear is setUpper limit ofWaiting for T on the basis of the lowest wind gearAAfter stabilization, can pass through TAAnd TSTo verify whether the correction degree of step S3 can actually achieve the expected effect. In the cooling mode, if TA≤TSNamely, the comfort of the air conditioner can achieve the expected effect; otherwise, the desired effect will not be achieved. The reason why the desired effect cannot be achieved is that the maximum operation load of the partial type air conditioner is compared with that of the partial type air conditionerThe installation and use environment is small, and/or the temperature T is set by the userSIs set too low. In this case, firstly, the third preset temperature T can be increased3As long as TA≤T3The comfort of the air conditioner can be regarded as reaching the expected effect; secondly, the comfort of the air conditioner can achieve the expected effect by properly reducing the rotating speed S of fresh air for part of air conditioners, particularly the outdoor environment temperature T represented by S41Outer ringAlthough the air conditioner is not high, the fresh air demand of the user under the subjective intention is stronger, at the moment, the comfort of the air conditioner can reach the expected effect in a mode of properly reducing the fresh air rotating speed S, and the high wind gear does not need to be reduced to the medium wind gear at a time.
In the present invention, the third preset temperature T3For example, 26 ℃ can be set, because 26 ℃ is most suitable for the requirement of human body comfort under normal conditions. The first preset rate may be specifically set according to the model parameter of the air conditioner, and may be set to 100r/10min, for example.
For part of air conditioner models and installation and use environments thereof, the process that the fresh air rotating speed S is reduced according to a first preset speed is also a process of stably seeking the best balance with the air conditioner refrigeration comfort, and is equivalent to further fine correction made on the basis of the correction degree of the step S3, so that the defect that the lowest comfort guarantee of the part of air conditioner models based on the installation and use environments is still low is overcome, the lowest comfort guarantee is further improved, the air conditioner models and the installation and use range thereof are widened, and the overall comfort experience of the air conditioner is better.
Preferably, step S56 includes the following specific operation steps:
s561: the fresh air rotating speed S is reduced according to a first preset speed;
s562: judging the indoor temperature TAWhether less than or equal to user-set temperature TsAnd a third predetermined temperature T3And/or judging whether the fresh air rotating speed S is reduced to the rated rotating speed of the lower fresh air gear;
s563: if so, stopping decreasing the fresh air rotating speed S and keeping the current rotating speed to operate; if not, return to step S562.
Specifically, step S562 specifies three conditions that the fresh air rotation speed S stops decreasing, which are further refinements made to the first preset condition, and as long as any one of the conditions is met, the fresh air rotation speed S stops decreasing, and at this time, keeping the current rotation speed of the fresh air rotation speed S running indicates that the comfort of the whole air conditioner has reached the expected effect equivalent to that of step S55. Therein, relating to the indoor temperature TABased on "ensuring air-conditioning refrigeration performance as necessary as a function of outdoor ambient temperature TOuter ringIs maintained or even raised "by the increase of the temperature, i.e. the level of temperature regulation; and the starting point of the air conditioner is based on another layer of ensuring the minimum fresh air requirement of the user, and further the minimum comfortable guarantee of the air conditioner is ensured from the two layers.
Preferably, in the cooling mode, in correspondence with the operating results S41 and/or S43, the method also directly comprises the following specific operating steps:
s55: the fresh air rotating speed S starts a gear F according to the fresh airOpenerThe rated rotational speed of the motor is kept unchanged.
In particular, the outdoor ambient temperature T represented by the operating result S41 corresponds toOuter ringThe fresh air demand is high, and the user' S subjective will is strong, and in the operation of step S3, the fresh air is set to the gear FIs provided withFace downward correction to get a new wind setting gear FIs provided withThe fresh air starting gear F to be lower than the upper levelOpener. Or in other words, corresponding to the operation result S41, it has been down-corrected by the primary fresh air damper, i.e., the fresh air setting gear F, in step S3Is provided withAlthough the wind gear is high, the fresh air starting gear FOpenerBut only a medium wind shield.
Therefore, based on another aspect of "guaranteeing the minimum fresh air demand of the user", the fresh air rotation speed S does not have a space to be repaired in the subsequent operation step, corresponding to the operation result S41, compared to the operation results S41' and/or S42; similarly, it corresponds to the operation result S43 becauseThe fresh air rotating speed S does not have a repair space. Therefore, the fresh air rotating speed S is directly started according to the fresh airOpenerThe rated rotating speed is kept unchanged, and the optimal balance between the refrigeration comfort level and the fresh air comfort level can be directly obtained.
Similarly, in the heating mode, the method is also applicable to the subsequent processes of executing steps S51-S56 and/or directly executing step S55, and only the steps S52, S53 and S562 are required to be executed with respect to the indoor temperature TAThe comparison relationship is modified appropriately.
