Detailed Description
In order to make the above objects, technical solutions and advantages of the present invention more comprehensible, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments of the present invention described herein are only some of the embodiments constituting the present invention, which are intended to be illustrative of the present invention and not limiting of the present invention, and the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
For convenience of description, the invention is to realize the fresh air control of the fresh air conditioner by setting three fresh air gears of low, medium and high so as to realize the matching of the fresh air volume of the fresh air conditioner with the fresh air gear at the current moment by adjusting and setting different gears. It should also be understood that the above-described settings are intended only to better explain the present invention to those skilled in the art, and should not be construed 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 also not set the fresh air gears, but directly meets the fresh air regulation needs through stepless speed regulation.
In the invention, the fresh air motor rotation speed S (hereinafter referred to as a fresh air rotation speed S) can also have an stepless speed regulating function besides meeting the fresh air gear setting, or in other words, the fresh air rotation speed S corresponding to each fresh air gear can also have a certain dynamic speed regulating interval. For example, if rated rotational speeds of the fresh air motor corresponding to the three fresh air gears of low, medium and high are 700r,1200r and 1700r, respectively, dynamic speed regulation intervals of the fresh air rotational speed S in the high wind gear can be set to (1200 r and 1700 r), and dynamic speed regulation intervals of the fresh air rotational speed S in the medium wind gear can be set to (700 r and 1200 r), respectively. Wherein, corresponding to the rated rotation speed of the fresh air motor, the fresh air quantity M corresponding to the three fresh air gears of low, medium and high is respectively 10M 3 /h、30m 3 /h、60m 3 And/h, the fresh air quantity M is increased and reduced along with the increase and the decrease of the fresh air rotating speed S.
All embodiments of the invention are mainly set with three fresh air gears of low, medium and high around a fresh air conditioner for specific development and explanation.
Example 1
As shown in fig. 1-3, the invention provides a fresh air control method, which comprises the following steps:
s1: receiving a fresh air starting signal in a refrigerating or heating mode;
s2: according to the temperature T of the outdoor environment Outer ring Is used for determining the upper limit F of the new wind gear Upper limit of ；
S3: according to the upper limit F of the new wind gear Upper limit of Setting a gear F for fresh air Is provided with Correcting to determine the fresh air starting gear F Opening and closing ；
S4: air conditioner starts gear F according to new trend Opening and closing And starting a fresh air fan.
Specifically, a fresh air setting gear F Is provided with The setting time can be set by the user at the beginning of the opening of the fresh air function or during the running of the fresh air functionThe change setting (corresponding to the fresh air switching signal in step S6 below) is made by the user. Of course, if the user does not perform the process of F at the beginning of the opening of the fresh air function Is provided with The air conditioner can also automatically default the latest fresh air running gear F to the current fresh air setting gear F Is provided with Or continue to use the last F Is provided with The invention does not set a gear F for fresh air Is provided with Any particular limitation is imposed on the special treatment of (c).
Taking a refrigeration mode as an example, since the refrigerating performance of the air conditioner is along with T Outer ring Is decreased with the increase of T, and the fresh air load Q is decreased with T Outer ring And increases with increasing numbers of (c). In the whole running process of the air conditioner, when a fresh air function is started, in order to avoid the influence of overlarge fresh air load Q on the refrigerating performance of the air conditioner, the fresh air quantity M can be properly regulated and reduced according to a fresh air load formula Q=M (h 1-h 2)/Vn, so that the fresh air load Q is properly reduced to ensure the refrigerating performance of the air conditioner. Taking the background technology as an example, under the same scene, if the fresh air quantity M is reduced to 20M 3 At/h, the fresh air load Q can be halved, thereby ensuring that the air conditioning refrigeration performance can follow the outdoor environment temperature T when necessary Outer ring Is maintained or even lifted.
According to the fresh air control method, the fresh air control device and the fresh air control method, the fresh air control device are based on the outdoor environment temperature T Outer ring For the upper limit F of fresh air gear Upper limit of Dividing setting is carried out, and then a fresh air starting gear F is carried out Opening and closing Will be represented by F Upper limit of 、F Is provided with The two values can be determined after the comprehensive judgment. Therefore, when the air conditioner is in refrigerating or heating operation, the opening of the fresh air fan not only fully considers the fresh air requirement under the subjective intention of a user, but also considers the outdoor environment temperature T Outer ring The influence of the maximum fresh air quantity on the refrigerating or heating performance of the air conditioner is improved, and compared with the prior art, the minimum comfort guarantee of the air conditioner on temperature regulation is improved, so that the comfort experience in the whole-course and multi-azimuth operation process of the air conditioner is guaranteed. Based on the above-mentioned inventive concept, the heating mode and the cooling mode are substantially the same as each other for the logic of the present invention, and the present invention is not described herein in detail.
As a preferred embodiment 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 at the starting moment of a refrigerating or heating mode;
s13: if yes, executing step S2; if not, the air conditioner sets a gear F according to fresh air Is provided with And starting a fresh air fan.
Specifically, taking the cooling mode as an example, when the cooling mode is started, the air conditioner needs to enter a rapid cooling stage, at this time, the requirement of a user on the cooling performance of the air conditioner is higher, and the cooling mode and the fresh air function are started simultaneously, so that the air conditioner needs to be improved in the cooling performance of the air conditioner, and load crowding to a larger extent is generated. The steps S11-S13 may be optimally set according to specific needs, for example, when the maximum running 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, so that relatively obvious load occupation is formed on the air cooling performance, and the steps S11-S13 are preferably set at this time; in contrast, the relatively significant load crowding may not be limited to the rapid cooling stage of the air conditioner, and steps S11 to S13 are not required. Therefore, the air conditioner is used for adjusting and controlling the comfort, the influence on the performance of the air conditioner and the installation and use environment of the air conditioner is fully considered, and the comfort experience of the air conditioner in the whole-course operation process is better.
In addition, with respect to the expression "simultaneously" in step S12, it will be understood by those skilled in the art that it may refer to: the fresh air opening signal is received within a shorter interval time under the opening time of the cooling or heating mode, and the shorter interval time can be any one of 1 minute, 5 minutes and 10 minutes.
Preferably, after step S4, the method further comprises the steps of:
s6: the setting gear F for the fresh air is received in the running process of the fresh air fan Is provided with And/or the outdoor ambient temperature T Outer ring Fresh air of (2)A switching signal;
s7: returning to step S2.
Specifically, as described above, the fresh air setting gear F Is provided with The fresh air function can be changed and set by a user in the running process of the fresh air function, for example, a wind gear is changed into a high wind gear, so that the fresh air requirement under the subjective intention of the user is more timely and fully reflected. In fact, whether based on the outdoor ambient temperature T Outer ring Is also based on the real-time change of the fresh air to set the gear F Is provided with The fresh air operation mode is possible to be switched, but the fresh air operation mode is required to have a certain variation amplitude compared with the fresh air operation mode, otherwise, the fresh air switching signal is difficult to trigger.
When the invention also comprises steps S6-S7, the gear F is started for fresh air Opening and closing Firstly, the latest expectation of a user on fresh air demand can be more timely matched, and secondly, the upper limit F of the fresh air gear can be more timely reflected Upper limit of Based on the outdoor ambient temperature T Outer ring The latest change of the air conditioner is further improved in the comfort experience of the air conditioner in the whole-course operation process on the basis of conforming to the use habit of a user for the regulation of the fresh air operation mode.
Preferably, step S2 comprises the following specific operating steps:
s21: in the refrigeration mode, the outdoor environment temperature T is judged Outer ring Whether or not it is greater than or equal to a first preset temperature T 1 The method comprises the steps of carrying out a first treatment on the surface of the Or in the heating mode, judging the outdoor environment temperature T Outer ring Whether or not it is equal to or less than a second preset temperature T 2 ；
S22: if yes, go to step S23; if not, executing step S24;
s23: determining a new wind gear upper limit F Upper limit of Is a middle wind shield;
s24: determining a new wind gear upper limit F Upper limit of Is a high wind gear.
Specifically, still taking the cooling mode as an example, when the outdoor ambient temperature T Outer ring Has reached a first preset temperature T 1 In this case, the refrigerating performance of the air conditioner is remarkably reduced, and the fresh air load Q is increasedMore obviously, at this time, for example, the fresh air sets a gear F Is provided with For a high wind gear, the running of the fresh air function is likely to not ensure that the fresh air function does not generate obvious load occupation on the air conditioning cold performance, and further the minimum comfort guarantee of the air conditioning on temperature adjustment is also not ensured, at this time, although the ensuring can be completed by means of the step S23, the step S23 can properly reduce the fresh air requirement of a user; on the other hand, the minimum comfort of the air conditioner in terms of temperature regulation can be ensured, without the aid of step S23. Therefore, on the basis of improving the minimum comfort guarantee of the air conditioner, the fresh air demand of the user at subjective will is fully considered to the greatest extent.
Preferably, the first preset temperature T 1 43 ℃.
Specifically, for most air conditioners circulating in the market at present, the setting of 43 ℃ has larger universality, and on the basis of improving the minimum comfort guarantee of the air conditioner based on temperature regulation, the air conditioner is favorable for fully considering the fresh air demand of a user at the maximum degree at subjective intention, and further, the comfort experience of the air conditioner in a refrigerating mode is better in whole course and multiple directions. Similarly, a second preset temperature T 2 For example, the temperature may be set to-10 ℃.
Preferably, step S4 includes the following four operation results:
s41: fresh air setting gear F Is provided with When the wind power is in a high wind power range, a fresh air fan is started according to the medium wind power range;
s41': fresh air setting gear F Is provided with When the air is in a high air level, the fresh air fan is started according to the high air level;
s42: fresh air setting gear F Is provided with When the wind is a middle wind gear, a fresh air fan is started according to the middle wind gear;
s43: fresh air setting gear F Is provided with And when the air is in a low air level, starting the fresh air fan according to the low air level.
As one example of the present invention, when setting the upper limit F of the fresh air gear Upper limit of At the lowest stroke stage, step S4 has and can only include the four operating results described above. Wherein the operation result S41 corresponds to step S23, and the operation result S41' corresponds to step S24. While the four operation results can be already obtainedThe minimum comfort guarantee of the air conditioner based on temperature adjustment is improved to a great extent.
Specifically, when the fresh air gear upper limit F Upper limit of At the lowest stroke gear, namely the upper limit F of fresh air gear Upper limit of Only the middle wind gear and the high wind gear can be obtained, namely, the two operation results corresponding to the step S2 and the steps S23 and S24 can be obtained. Because of the difference between the steps S23 and S24, the step S4 is to set the gear F in the fresh air Is provided with Under the same condition of high wind gear, two completely different running results of S41 and S41' are generated; the operation results S42 and S43 are obtained as a general operation result, and are independent of the distinction between the steps S23 and S24.
More specifically, the upper limit F of the fresh air gear Upper limit of Is combined with fresh air to set a gear F Is provided with After the operation of step S3, it can only produce four running results in total, corresponding to step S4. I.e. corresponding to the upper limit F of the fresh air gear Upper limit of The lowest setting of the middle wind level is equivalent to the improvement of the correction threshold of the step S3, namely, no matter the outdoor environment temperature T Outer ring How to change, all avoid setting the gear F for fresh air Is provided with The excessive correction of the air conditioner is performed on the other layer of 'ensuring the minimum fresh air requirement of the user', so that the minimum comfort guarantee of the air conditioner is improved.
Preferably, in the cooling mode, the method further comprises the following specific operating steps, corresponding to the operating results S41' and/or S42:
s51: judging the indoor temperature T A Whether or not to stabilize;
s52: if yes, judging the indoor temperature T A Whether or not to be less than or equal to the user-set temperature T s The method comprises the steps of carrying out a first treatment on the surface of the If not, returning to the step S51;
s53: if yes, go to step S55; if not, judging the indoor temperature T A Whether or not it is less than a third preset temperature T 3 ；
S54: if yes, go to step S55; if not, executing step S56;
s55: fresh air rotating speed S starts gear F according to fresh air Opening and closing Is maintained unchanged;
s56: and the fresh air rotating speed S is reduced according to the first preset speed, and the fresh air rotating speed S stops reducing and keeps the current rotating speed to run after the first preset condition is triggered.
Specifically, as one example of the present invention, step S51 may take the following determination modes: when the indoor temperature T A When the fluctuation range of the temperature sensor is smaller than or equal to a first fluctuation threshold value in a first preset duration, judging the indoor temperature T A Stabilizing; conversely, the indoor temperature T A Unstable, the above determination should be continued. The first preset time period may be set to, for example, 10 minutes, and the first fluctuation threshold may be set to, for example, 0.5 ℃.
In the invention, the upper limit F of the fresh air gear is set Upper limit of On the basis of lowest middle wind gear, wait T A After stabilization, it can pass through T A And T is S Is used to verify whether the correction degree in step S3 can actually achieve the expected effect. In the cooling mode, if T A ≤T S I.e. the comfort of the air conditioner can achieve the expected effect; on the contrary, the intended effect will not be achieved. The reason why the expected effect cannot be achieved is that the maximum operation load of the partial model air conditioner is small compared with the installation and use environment thereof, and/or the user sets the temperature T S Is set too low. At this time, first, the third preset temperature T can be added 3 So long as T A ≤T 3 The comfort of the air conditioner can be considered to achieve the expected effect; secondly, the air conditioner with partial model can also enable the comfort of the air conditioner to achieve the expected effect by properly reducing the fresh air rotating speed S, in particular to the outdoor environment temperature T represented by S41 Outer ring Although not high, the fresh air demand of the user is stronger under subjective intention, at the moment, the comfort of the air conditioner can reach the expected effect by properly reducing the fresh air rotating speed S, and the user does not need to reduce the high wind gear to the middle wind gear.
In the present invention, the third preset temperature T 3 For example, 26 c may be set, since 26 c is the most suitable for human comfort requirements in the normal case. The first preset rate can be performed according to the model parameters of the air conditionerThe specific setting may be, for example, 100r/10min.

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 T A Whether or not to be less than or equal to the user-set temperature T s And a third preset temperature T 3 Any one of the above, and/or judging whether the fresh air rotating speed S is reduced to the rated rotating speed of the first-stage fresh air gear or not;
s563: if yes, stopping the fresh air rotating speed S from falling and keeping the current rotating speed to run; if not, return to step S562.
Specifically, step S562 actually defines three conditions for stopping the decrease of the fresh air rotation speed S, which is a further refinement of the first preset condition, and as long as any one of the conditions is satisfied, the decrease of the fresh air rotation speed S is stopped, and at this time, the fresh air rotation speed S keeps the current rotation speed running, which means that the overall comfort of the air conditioner has reached the effect equivalent to that expected in step S55. Wherein relates to the indoor temperature T A Based on "ensuring that the air-conditioning refrigeration performance can follow the outdoor ambient temperature T when necessary Outer ring To be maintained or even lifted ", i.e. temperature regulation; the other condition of the degree of the decrease of the fresh air rotating speed S is directly related, and the starting point is based on the other layer of ensuring the minimum fresh air requirement of the user, so that the minimum comfort guarantee of the air conditioner is further ensured from the two layers.
Preferably, in the refrigeration mode, the method further comprises the following specific operating steps directly, corresponding to the operating results S41 and/or S43:
s55: fresh air rotating speed S starts gear F according to fresh air Opening and closing Is maintained constant.
Specifically, it corresponds to the operation result S41, which represents the outdoor environment temperature T Outer ring The fresh air demand is higher and the subjective will of the user is stronger, and in the operation of step S3, the fresh air setting gear F Is provided with Face downward correction to obtain a fresh air setting gear F of the ratio Is provided with Fresh air starting gear F lower than previous stage Opening and closing . Or in other words, corresponding to the operating result S41, which has been modified by the first fresh air register in step S3, i.e. the fresh air setting register F Is provided with A fresh air starting gear F although the wind is in a high wind gear Opening and closing But only a mid-range wind gear.
Therefore, based on the other layer of the ' ensuring the minimum fresh air requirement of the user ', compared with the operation results S41' and/or S42, the fresh air rotating speed S corresponds to the operation result S41, and no space is continuously repaired in the subsequent operation steps; similarly, the operation result S43 corresponds to the fresh air rotation speed S itself, and no repair space exists. So the fresh air rotating speed S is directly according to the fresh air starting gear F Opening and closing The rated rotation speed of the air conditioner 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 in the subsequent steps of executing steps S51-S56 and/or directly executing step S55, and only the indoor temperature T in steps S52, S53, S562 is required A Is carried out according to the comparison relation of (2) and adapting to the modification.
