Fresh air comfort adjustment method, device, fresh air conditioner, computer storage medium

technical field

The present invention relates to the technical field of air conditioning, in particular, to a fresh air comfort adjustment method, a device, a fresh air conditioner, and a computer storage medium.

Background technique

As people pay more and more attention to indoor air quality, fresh air air conditioners are becoming more and more popular because they can provide fresh air ventilation functions in closed rooms. In the prior art, when the fresh air mode of the fresh air conditioner is running at the same time as the cooling or heating mode, in order to avoid causing uneven indoor temperature and humidity and thus affecting the fresh air experience of the user, the fresh air duct of the fresh air conditioner is usually connected to the circulating air of the internal unit. This leads to the fact that when the outdoor fresh air enters the room, its transmission path must first pass through the indoor heat exchanger, thus:

In the cooling mode, if the outdoor temperature is high at this time, when the fresh air mode is turned on, the outdoor fresh air will affect the original heat exchange of the indoor unit when it passes through the indoor heat exchanger, resulting in poor evaporation effect, and the indoor air outlet temperature will be higher than that when the fresh air mode is turned on. The front rise will affect the cooling effect in the room. Conversely, in the heating mode, if the outdoor temperature is low at this time, when the fresh air mode is turned on, the condensation effect of the indoor heat exchanger will also be deteriorated, and the indoor outlet air temperature will be lower than before the fresh air mode is turned on, which will affect the indoor temperature. Heating effect.

The above two situations will seriously affect the user's fresh air experience. This poor fresh air experience is at least reflected in: 1) The temperature comfort caused by the fresh air mode is turned on will be worse in stages, or at least the same. It will be much worse than not turning on the fresh air mode; 2) The user usually has to wait for a longer time before entering a comfortable state that meets the user's settings.

Contents of the invention

In view of this, the technical problems to be solved by the present invention are as follows: the first aspect is to propose a fresh air comfort adjustment method, so that after the fresh air mode of the fresh air conditioner is turned on, the fresh air experience of the user is always guaranteed on the basis of low energy consumption as much as possible.

In order to solve the above-mentioned technical problem in the first aspect, the present invention proposes a fresh air comfort adjustment method for fresh air air conditioners, which includes the following steps:

S1: Determine whether the fresh air mode is turned on;

S2: If yes, execute step S3; if no, return to step S1;

S3: Determine whether the operating environment at the moment when the fresh air mode is turned on meets the first trigger condition;

S4: If yes, execute step S5; if no, keep the fresh air conditioner in the current operating mode;

S5: The fresh air conditioner operates according to the first operation mode;

Wherein, the first trigger condition is used to characterize: the user's fresh air experience is based on the critical condition of the operating environment when the fresh air mode is turned on; the first operating mode is used to always ensure the user's fresh air experience.

When the operating environment at the moment when the fresh air mode is turned on does not meet the first trigger condition, even if the fresh air conditioner does not operate according to the first operating mode, it can still guarantee the user's fresh air experience; Fresh air experience. As a result, after the fresh air mode of the fresh air conditioner is turned on, the whole process can be realized to "always ensure the user's fresh air experience on the basis of low energy consumption as much as possible".

Preferably, when the first trigger condition includes:

a. The absolute value of the first temperature difference | T _outside - T _inside | < the first preset temperature difference ΔT ₁ ;

b. The absolute value of the second temperature difference | _Tinner - _Tset |>the second preset temperature difference ΔT ₂ ;

c. The fresh air air conditioner operates in cooling mode and T _OUT > the first preset outdoor temperature T' _OUT , or the fresh air air conditioner operates in heating mode and T _OUT < the second preset outdoor temperature T"_OUT;

Then the first operation mode includes: the compressor of the fresh air conditioner operates according to the second operation mode;

Wherein, _{Toutside, Tinside, and Tset} respectively represent the outdoor ambient temperature, indoor ambient temperature, and user-set temperature of the fresh air conditioner at the current operating moment; the second operating mode is used to ensure the fresh air experience of the user all the time.

By further refining the first trigger condition and the first operation mode, the first operation mode of the fresh air conditioner can be further evolved into the second operation mode of the compressor, so that when the fresh air mode is turned on, even if the T is _in demand In the stage of rapid cooling or heating, the operating frequency of the compressor can also be increased to ensure that the evaporation effect or condensation effect of the indoor heat exchanger will not be significantly deteriorated.

Preferably, ΔT ₁ =5°C, ΔT ₂ =8°C.

Regardless of cooling mode or heating mode, ΔT ₁ = 5°C and ΔT ₂ = 8°C can be used as a universal reference, which is applicable to most fresh air conditioners and households.

Preferably, after step S5, the method further includes the following steps:

S6: judging whether the operating environment satisfies the second trigger condition in real time or periodically;

S7: If yes, execute step S8; if no, return to step S5;

S8: The fresh air conditioner returns to the operating mode before the fresh air mode is turned on;

Wherein, at least one of the second trigger condition and the first trigger condition is a failure condition.

When the operating environment has met the second trigger condition, that is, the trigger factors corresponding to the first trigger condition are no longer fully satisfied. At this time, even if the fresh air conditioner returns to the operating mode before the fresh air mode is turned on again, it is enough to fully guarantee the user’s fresh air experience, thereby It is beneficial to reduce the energy consumption of the fresh air conditioner and/or relatively improve the ventilation function of the fresh air.

Preferably, the second trigger condition is T _within = T _set .

No matter in the cooling mode or in the heating mode, when _Tin = _Tset , it means that the fresh air conditioner has entered a comfortable state that meets the user's setting at least at the current moment. At this time, _Tin has not only fully reached _the Tset level and relatively far away _{from outside} T, that is to say, the two trigger factors related to _inside T in the first trigger condition are no longer satisfied. There is no need to worry about affecting the user's fresh air experience, which is conducive to further strengthening the user's fresh air experience guarantee.

Preferably, the second operating mode includes the following specific operating steps:

S51: Real-time or regular monitoring of the indoor heat exchanger coil temperature T _plate ;

S52: Determine whether the third absolute value of the temperature difference|T _plate -T' _plate |≥the third preset temperature difference _ΔT3 is established, wherein, the T' _plate is the coil temperature of the indoor heat exchanger at the moment when the fresh air mode is turned on;

S53: If yes, execute step S54; if no, execute step S6;

S54: After the operating frequency of the compressor increases by the first preset frequency value F, and keeps running for the first preset duration X, return to step S52.

When T is _in the stage of rapid cooling or heating, ensure that the indoor air outlet temperature does not fluctuate too much compared with before the fresh air mode is turned on, and is basically at a comparable level. Among them, the operating frequency of the compressor adopts the incremental method of retesting. First, the impact of the opening of the fresh air mode on the user's fresh air experience itself gradually appears and gradually weakens after a certain period of time. On the premise of ensuring the user's fresh air experience, it is conducive to the proper energy saving and consumption reduction of the fresh air air conditioner; second, on the premise of ensuring the smooth operation of the compressor, it can gradually ensure the adaptability of the compressor's operating frequency to its current operating conditions.

Preferably, before step S1, the method further includes the following steps:

ST1: Receive the open signal of the fresh air mode;

ST2: Determine whether the operating environment at the moment of receiving the signal satisfies the third trigger condition;

ST3: If yes, execute step ST4; if not, return to step ST2;

ST4: The fresh air mode is turned on;

Wherein, the first trigger condition constitutes a necessary condition of the third trigger condition.

In some more extreme working conditions, the _{inside of} the T may be in a more urgent cooling or heating stage, but the fresh air ventilation may not be too urgent. At this time, even if the open signal of the fresh air mode is received , the opening of the fresh air mode may also be properly delayed until the operating environment at the current moment no longer satisfies the third trigger condition as the fresh air conditioner continues to operate.

The technical problem to be solved by the present invention is that: the second aspect provides a fresh air comfort adjustment device, and/or the third aspect provides a fresh air air conditioner, and/or the fourth aspect provides a computer-readable storage medium, so that After the fresh air mode of the fresh air conditioner is turned on, it will always ensure the user's fresh air experience on the basis of low energy consumption.

Detailed ways

In order to make the above objectives, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described in the present invention are only part of the embodiments of the present invention, which are only used to explain the present invention and do not constitute a limitation to the present invention. The embodiments and the features in the embodiments can be combined with each other.

Example 1

As shown in Figure 1-2, the present invention proposes a fresh air comfort adjustment method for fresh air air conditioners, including the following steps:

S1: Determine whether the fresh air mode is turned on;

S2: If yes, execute step S3; if no, return to step S1;

S3: Determine whether the operating environment at the moment when the fresh air mode is turned on meets the first trigger condition;

S4: If yes, execute step S5; if no, keep the fresh air conditioner in the current operating mode;

S5: The fresh air conditioner operates according to the first operation mode;

Wherein, the first trigger condition is used to characterize: the user's fresh air experience is based on the critical condition of the operating environment when the fresh air mode is turned on; the first operating mode is used to always ensure the user's fresh air experience.

Specifically, the first trigger condition can be set by the manufacturer as a universal default factory setting, or the user can customize the components of the first trigger condition according to factors such as geoclimatic characteristics. Factors such as habitual preferences change the critical values of the relevant components. The present invention does not need to make special limitations on the constituent elements of the first trigger condition and their critical values, which are only used to represent: the user's fresh air experience is based on the critical conditions of the operating environment when the fresh air mode is turned on, that is, when the fresh air mode is turned on. When the operating environment meets the critical condition, if the user does not take the initiative and/or the fresh air conditioner itself does not automatically take further preventive measures, although fresh air ventilation can be guaranteed, the user will soon feel that the temperature comfort will be significantly worse A lot, and/or the waiting time to endure and/or enter the set comfortable state will inevitably be much longer, which will cause the user's fresh air experience to remain unsatisfactory.

The first operating mode will be obviously different from the regular operating mode of the fresh air conditioner. It is an exclusive operating mode tailored to always ensure the user's fresh air experience on the basis that the regular operating mode of the fresh air conditioner cannot guarantee the user's fresh air experience. . Of course, this exclusive operation mode may consume more energy than the conventional operation mode (corresponding to the second operation mode below), and/or it will always ensure the user's fresh air experience by appropriately reducing the fresh air exchange. Of course, this is appropriate The degree of reduction must be established outside the user's perceivable range of fresh air experience, or within the acceptable range of reduction in ventilation. Therefore, the specific setting of the first trigger condition can also be related to the user's energy consumption and ventilation preference for the fresh air conditioner, that is, the user can comprehensively consider geoclimate characteristics, personal perception differences and habit preferences, energy consumption and ventilation preference, The performance of the fresh air conditioner, the installation environment and other factors are used to specifically set the first trigger condition.

Therefore, when the operating environment at the moment when the fresh air mode is turned on does not meet the first trigger condition, even if the fresh air conditioner does not operate according to the first operating mode, the fresh air experience of the user can be guaranteed; otherwise, the fresh air conditioner operates according to the first operating mode. Always guarantee the user's fresh air experience. As a result, after the fresh air mode of the fresh air conditioner is turned on, the whole process can be realized to "always ensure the user's fresh air experience on the basis of low energy consumption as much as possible".

Preferably, when the first trigger condition includes:

a. The absolute value of the first temperature difference | T _outside - T _inside | < the first preset temperature difference ΔT ₁ ;

b. The absolute value of the second temperature difference | _Tinner - _Tset |>the second preset temperature difference ΔT ₂ ;

c. The fresh air air conditioner operates in cooling mode and T _OUT > the first preset outdoor temperature T' _OUT , or the fresh air air conditioner operates in heating mode and T _OUT < the second preset outdoor temperature T"_OUT;

Then the first operation mode includes: the compressor of the fresh air conditioner operates according to the second operation mode;

Wherein, _Toutside, Tinside _{, and Tset} respectively represent the outdoor ambient temperature, indoor ambient temperature, and user-set temperature of the fresh air conditioner at the current operating moment; the second operating mode is used to ensure the fresh air experience of the user all the time.

Specifically, taking the cooling mode of the fresh air conditioner as an example, when _{the outside of} T is overheated and the fresh air mode is turned on, if _{the inside of} T is not only far from _{the set} level of T but also relatively close to _{the outside of} T at this opening moment, then only the appropriate Relatively mild measures such as reducing fresh air ventilation cannot guarantee the user's fresh air experience. Because at this moment, according to the user's urgent wishes, the _{interior of} the T is in the stage of rapid cooling, and the evaporation effect of the indoor heat exchanger will become worse due to the operating environment. Relatively mild methods such as fresh air ventilation are obviously of little help to improve the evaporation effect of the indoor heat exchanger. At this time, the energy consumption of the fresh air conditioner must be increased, that is, the operating frequency of the compressor must be increased to ensure the indoor heat exchanger. The evaporation effect will not be significantly worse. The second operation mode will be obviously different from the normal operation mode of the compressor, which is when the normal operation mode of the compressor is not enough to ensure the user's fresh air experience, and/or when the user's energy consumption and ventilation preference, fresh air Based on factors such as air-conditioning performance (whether it supports the fresh air reduction function), an exclusive operating mode tailored to ensure the user's fresh air experience at all times. Among them, T', ΔT ₁ , and ΔT ₂ can be set to 35°C, 5°C, and 8°C, respectively, for example; and the logic of _the heating mode corresponding to T" _outside is the same as that of the cooling mode, and will not be repeated here. Of course, T" can be set to 0°C or -10°C, _for example.

Therefore, the first trigger condition and the first operation mode are both 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 when the fresh air mode is turned on, even if it is _within T In the stage where rapid cooling or heating is required, the operating frequency of the compressor can also be increased to ensure that the evaporation effect or condensation effect of the indoor heat exchanger will not deteriorate significantly.

Preferably, ΔT ₁ =5°C, ΔT ₂ =8°C.

Specifically, whether it is cooling mode or heating mode, ΔT ₁ =5°C and ΔT ₂ =8°C can be used as a universal reference, which is applicable to most fresh air conditioners and user families.

Preferably, after step S5, the method further includes the following steps:

S6: judging whether the operating environment satisfies the second trigger condition in real time or periodically;

S7: If yes, execute step S8; if no, return to step S5;

S8: The fresh air conditioner returns to the operating mode before the fresh air mode is turned on;

Wherein, at least one of the second trigger condition and the first trigger condition is a failure condition.

Specifically, no matter it is the first operation mode of the fresh air conditioner, or the compressor further adopts the second operation mode based on the first operation mode, either it may relatively reduce the fresh air ventilation, or it will inevitably increase the performance of the fresh air conditioner. consumption. When the operating environment has met the second trigger condition, that is, the trigger factors corresponding to the first trigger condition are no longer fully satisfied. At this time, even if the fresh air conditioner returns to the operating mode before the fresh air mode is turned on again, it is enough to fully guarantee the user’s fresh air experience, thereby It is beneficial to reduce the energy consumption of the fresh air conditioner and/or relatively improve the ventilation function of the fresh air.

Preferably, the second trigger condition is T _within = T _set .

Specifically, no matter in the cooling mode or in the heating mode, when T _{inside =} T _{is set} , it means that the fresh air conditioner has entered a comfortable state that meets the user’s settings at least at the current moment. It reaches _{the set} level of T and is relatively far away _{from the outside of} T, that is, the two trigger factors related to _{the inside of} T in the first trigger condition are no longer satisfied. At this time, the fresh air conditioner can be restored to the operating mode before the fresh air mode is turned on. , and there is no need to worry about affecting the user's fresh air experience, which is conducive to further strengthening the security of the user's fresh air experience.

Preferably, the second operating mode includes the following specific operating steps:

S51: Real-time or regular monitoring of the indoor heat exchanger coil temperature T _plate ;

S52: Determine whether the third absolute value of the temperature difference|T _plate -T' _plate |≥the third preset temperature difference _ΔT3 is established, wherein, the T' _plate is the coil temperature of the indoor heat exchanger at the moment when the fresh air mode is turned on;

S53: If yes, execute step S54; if no, execute step S6;

S54: After the operating frequency of the compressor increases by the first preset frequency value F, and keeps running for the first preset duration X, return to step S52.

Specifically, F can be set to 2Hz, for example, and X can be set to 2 minutes, and then according to the user's urgent wishes, when T is _in the stage of rapid cooling or heating, the indoor temperature can be improved by increasing the operating frequency of the compressor. The evaporation or condensation effect of the heater ensures that the indoor outlet air temperature will not fluctuate too much compared with before the fresh air mode is turned on, and is basically at a comparable level. Among them, the operating frequency of the compressor adopts the incremental method of retesting. First, the impact of the opening of the fresh air mode on the user's fresh air experience itself gradually appears and gradually weakens after a certain period of time. On the premise of ensuring the user's fresh air experience, it is conducive to the proper energy saving and consumption reduction of the fresh air air conditioner; second, on the premise of ensuring the smooth operation of the compressor, it can gradually ensure the adaptability of the compressor's operating frequency to its current operating conditions.

Preferably, before step S1, the method further includes the following steps:

ST1: Receive the open signal of the fresh air mode;

ST2: Determine whether the operating environment at the moment of receiving the signal satisfies the third trigger condition;

ST3: If yes, execute step ST4; if not, return to step ST2;

ST4: The fresh air mode is turned on;

Wherein, the first trigger condition constitutes a necessary condition of the third trigger condition.

Specifically, in some more extreme working conditions, when a signal to turn on the fresh air mode is received, the fresh air mode can also be delayed to start. For example, compared with the critical value of the first trigger condition, according to the urgent wishes of the user, _T may be in a more urgent need for rapid cooling or heating, while fresh air ventilation may not be too urgent. At this time, even if the opening signal of the fresh air mode is received, the opening of the fresh air mode can be appropriately delayed until the operating environment at the current moment no longer satisfies the third trigger condition as the fresh air conditioner continues to operate.
