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.
Example 1
As shown in fig. 1-2, the invention provides a fresh air comfort level adjusting method for a fresh air conditioner, which comprises the following steps:
s1: judging whether a fresh air mode is started or not;
s2: if yes, go to step S3; if not, returning to the step S1;
s3: judging whether the operating environment at the moment of starting the fresh air mode meets a first trigger condition or not;
s4: if yes, go to step S5; if not, the fresh air conditioner keeps the current operation mode;
s5: the fresh air conditioner operates according to a first operation mode;
wherein the first trigger condition is used to characterize: the user fresh air experience is based on the critical condition of the operation environment of the fresh air mode at the starting time; the first operation mode is used for always guaranteeing the fresh air experience of the user.
Specifically, the first trigger condition may be a default factory setting for universality performed by a manufacturer, or may be a user-defined setting for a constituent element of the first trigger condition according to factors such as a geographical climate characteristic, and of course, the user may change a critical value of a relevant constituent element according to factors such as a personal perception difference and a habit preference. The invention does not need to be particularly limited to the components of the first trigger condition and the critical values thereof, and they are only used to characterize: the user's new trend is experienced and is opened its operational environment's critical condition under the moment based on the new trend mode, promptly when the operational environment under the moment is opened to the new trend mode satisfies this critical condition, if the user does not take further precaution measure voluntarily and/or new trend air conditioner self is not automatic, though new trend is taken a breath and can be guaranteed, but the user will perceive the temperature comfort very fast and can obviously worsen a lot, and/or enter into the tolerance latency who sets for comfortable state afterwards and will certainly lengthen a lot, thereby can lead to user's new trend to experience still not very beautiful.
The first operation mode is obviously different from the conventional operation mode of the fresh air conditioner, and is an exclusive operation mode which is tailored for ensuring the fresh air experience of the user all the time on the basis that the conventional operation mode of the fresh air conditioner cannot be enough to ensure the fresh air experience of the user. Of course, the exclusive operation mode may consume more energy than the conventional operation mode (which may correspond to the second operation mode below), and/or may always ensure the user's fresh air experience by properly adjusting the fresh air ventilation, and of course, the proper adjustment degree must be established outside the sensible range of the user to the fresh air experience or within the acceptable range of the ventilation adjustment. Therefore, the specific setting of the first trigger condition can be related to the energy consumption and ventilation preference degree of the user on the fresh air conditioner, namely, the user can comprehensively consider the factors such as the geographical climate characteristic, the personal perception difference and habit preference, the energy consumption and ventilation preference degree, the performance of the fresh air conditioner, the installation environment and the like to perform the specific setting of the first trigger condition.
Therefore, when the operation environment at the moment of starting the fresh air mode does not meet the first trigger condition, even if the fresh air conditioner does not operate according to the first operation mode, the fresh air experience of a user can be ensured; otherwise, the fresh air conditioner operates according to the first operation mode to ensure the fresh air experience of the user all the time. Therefore, after the fresh air mode of the fresh air conditioner is opened, the whole process is realized to ensure the experience of the fresh air of the user all the time on the basis of low energy consumption.
Preferably, when the first trigger condition includes:
a. absolute value of first temperature difference | TOuter cover-TInner part< first preset temperature difference Δ T1；
b. Second absolute value of temperature difference | TInner part-TIs provided with| greater than second predetermined temperature difference Δ T2；
c. Fresh air conditioner running in refrigeration mode and TOuter cover> first preset outdoor temperature T'Outer coverOr the fresh air conditioner runs in a heating mode and TOuter cover< second preset outdoor temperature T "Outer cover；
The first operating mode comprises: the compressor of the fresh air conditioner operates according to a second operation mode;
wherein, TOutside, outside,TInside, is,TIs provided withRespectively representing the outdoor environment temperature, the indoor environment temperature and the user set temperature of the fresh air conditioner at the current operation moment; the second operation mode is used for always guaranteeing the fresh air experience of the user.
Specifically, taking the refrigeration mode of the fresh air conditioner as an example, when T isOuter coverWhen the fresh air mode is started due to overheating, if the fresh air mode is started at the starting momentTInner partNot only far short of TIs provided withHorizontal and also relatively close to TOuter coverAnd at the moment, the fresh air experience of the user cannot be ensured only by a relatively mild means such as properly adjusting and reducing the fresh air ventilation and the like. Because at this point, T is the most urgent of the userInner partThe indoor heat exchanger is in a stage needing rapid cooling, the evaporation effect of the indoor heat exchanger is more obvious due to the operating environment, at the moment, the evaporation effect of the indoor heat exchanger is almost useless for improving by only using a relatively mild means such as properly adjusting and reducing fresh air and exchanging air, and at the moment, the energy consumption of a fresh air conditioner is required to be improved, namely, the operating frequency of a compressor is increased to ensure that the evaporation effect of the indoor heat exchanger is not obviously poor. The second operation mode is obviously different from the conventional operation mode of the compressor, and is an exclusive operation mode tailored for always ensuring the user fresh air experience on the basis that the conventional operation mode of the compressor is not enough to ensure the user fresh air experience and/or comprehensively considering the user energy consumption, the ventilation preference degree, the fresh air conditioning performance (whether the fresh air adjustment and reduction function is supported) and other factors. Wherein, T'Outer cover、ΔT1、ΔT2For example, the temperatures can be set to 35 ℃, 5 ℃ and 8 ℃; and T'Outer coverThe corresponding heating mode has the same logic as the cooling mode, and will not be repeated herein, of course T "Outer coverFor example, it may be set to 0 ℃ or-10 ℃.
Therefore, the first trigger condition and the first operation mode are further refined, and the first operation mode of the fresh air conditioner can be further evolved into the second operation mode of the compressor, so that the fresh air mode is started even if T is the valueInner partUnder the stage of needing rapid temperature reduction or temperature rise, the evaporation effect or the condensation effect of the indoor heat exchanger can not be obviously deteriorated by improving the running frequency of the compressor.
Preferably, Δ T1＝5℃、ΔT2＝8℃。
Specifically, Δ T in either cooling mode or heating mode1＝5℃、ΔT2The temperature of 8 ℃ can be used as a universal reference standard, and the method is suitable for most fresh air conditioners and the families of usersA court is provided.
Preferably, after step S5, the method further comprises the steps of:
s6: judging whether the operating environment meets a second trigger condition in real time or regularly;
s7: if yes, go to step S8; if not, returning to the step S5;
s8: the fresh air conditioner is recovered to the operation mode before the fresh air mode is started;
the second trigger condition is at least mutually invalid with one of the first trigger conditions.
Specifically, no matter be the first mode of operation of fresh air conditioner, still the compressor further adopts the second mode of operation on first mode of operation basis, it is perhaps to adjust down the fresh air and take a breath relatively, or will certainly improve fresh air conditioner energy consumption. After the operating environment has satisfied the second trigger condition, the trigger factor that corresponds first trigger condition is no longer all satisfied promptly, even if the new trend air conditioner resumes to the operating mode before the new trend mode is opened again this moment, also is enough to guarantee completely that the user new trend is experienced to be favorable to reducing new trend air conditioner energy consumption and/or relatively improving new trend function of taking a breath.
Preferably, the second trigger condition is TInner part＝TIs provided with。
Specifically, when T is in either the cooling mode or the heating modeInner part＝TIs provided withThat is, the fresh air conditioner enters a comfortable state according with the user setting at least at the current moment, and T is carried out at the momentInner partNot only has already fully reached TIs provided withHorizontal and also relatively largely away from TOuter coverI.e. with T in the first trigger conditionInner partTwo related trigger factors are not satisfied any more, and the fresh air conditioner can be completely restored to the operation mode before the fresh air mode is started, so that the influence on the fresh air experience of a user is not needed to be worried about, and the further enhancement of the fresh air experience guarantee of the user is facilitated.
Preferably, the second operation mode includes the following specific operation steps:

S52: judging the absolute value | T of the third temperature differenceDish-T'Dish| ≧ third preset temperature difference Δ T3Is not true, wherein T'DishThe temperature of the coil pipe of the indoor heat exchanger at the moment of starting the fresh air mode;
s53: if yes, go to step S54; if not, go to step S6;
s54: and after the compressor operation frequency is increased by the first preset frequency value F and the operation is maintained for the first preset time length X, returning to the step S52.
Specifically, F may be set to 2Hz, for example, and X may be set to 2 minutes, for example, and further T may be set at the user's willInner partWhen the indoor heat exchanger is in a stage needing rapid cooling or heating, the evaporation effect or the condensation effect of the indoor heat exchanger is improved by increasing the running frequency of the compressor, so that the fluctuation of the indoor air outlet temperature is ensured not to be too large compared with that before the fresh air mode is started, and the indoor air outlet temperature is basically at a proper level. Firstly, the influence of the opening of the fresh air mode on the fresh air experience of a user is gradually shown and gradually tends to weaken after being adhered for a certain time, and therefore the fresh air conditioner is favorable for proper energy conservation and consumption reduction on the premise of ensuring the fresh air experience of the user; secondly, on the premise of ensuring the stable operation of the compressor, the adaptation degree of the operation frequency of the compressor to the current operation condition can be gradually ensured.

ST 1: receiving an opening signal of a fresh air mode;
ST 2: judging whether the operating environment at the signal receiving moment meets a third trigger condition or not;
ST 3: if yes, go to step ST 4; if not, return to step ST 2;
ST 4: starting a fresh air mode;
wherein the first trigger condition constitutes a requirement of the third trigger condition.
In particular, under some more extreme conditions, when receivedWhen the opening signal of new trend mode, the new trend mode also can postpone and open. For example, T is compared with the critical value of the first trigger condition according to the user's urgent intentionInner partThe fresh air ventilation system has the advantages that the fresh air ventilation system is possibly in a more urgent stage needing rapid cooling or heating, the fresh air ventilation system is not too urgent, even if the opening signal of the fresh air mode is received, the opening of the fresh air mode can be delayed properly until the running environment at the current moment does not meet the third triggering condition along with the continuous running of the fresh air conditioner.
