Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention mainly discloses a method for continuously operating an air conditioner at low power, which continuously operates the air conditioner for more than one day, two days, more days, even one month, one quarter or one year and the like under specific conditions, and even operates all the time. During the continuous operation of the air conditioner, the total output power of the air conditioner is between 100W and 1500W, and even when the air conditioner has the highest power output, the total output power of the air conditioner is lower than that of the air conditioner in the normal state. Because the air conditioner runs for a long time, wall bodies, furniture and the like in a room are kept in a range close to the temperature required by a user, when a new temperature requirement of the user is detected, and the temperature is adjusted again, the amplitude required to be adjusted is very small, meanwhile, because the temperature of articles in the room is smaller in difference with the required temperature, the room temperature can be adjusted and controlled by very little cold energy or heat energy, the requirement of the user can be met in a short time, and further the energy loss caused by the high-power work of the air conditioner is avoided. The control method of the air conditioner can be used in various occasions, such as a cooler area, a lower environment temperature, such as-6-16 ℃, and low-power consumption continuous heating. The required temperature of the room is set to be 18 ℃, the air conditioner is very comfortable after a user enters the room, and if the user adjusts a new target temperature, the air conditioner can adjust the temperature to the target temperature in a very short time, so that the energy is saved, and the comfort level of the user is greatly improved; because the room is kept at the temperature of about 18 ℃, the user can experience a comfortable state whenever entering the room, the long-time waiting of the user is avoided, and the phenomenon that the user forgets to turn on the air conditioner before returning home is also avoided. In the low-power continuous working mode, the temperature in a room is closer to the temperature required by a user, when the user enters the room, in order to reduce the influence of noise generated by the air conditioner on the user, the air conditioner enters a noise reduction mode, in the mode, the rotating speed of the wind wheel is reduced, meanwhile, the operating frequency of the compressor is increased, and the energy output is increased, so that the requirement of the user on the room temperature is met, and the noise reduction and the temperature regulation are highly uniform. The mode is carried out in the low-power continuous working mode of the air conditioner, so that the noise reduction and the temperature regulation can achieve good effects. In a similar way, after the user goes out from the room, when the user does not exist in the room, the air conditioner reduces the frequency of the compressor and improves the rotating speed of the wind wheel, so that the energy is fully and quickly input into the room, the purpose of keeping the temperature of the room is achieved, the frequency of the compressor is reduced to achieve the purpose of saving energy, and the air conditioner is highly unified with energy conservation after heat preservation and energy conservation are achieved, so that the user can use the air conditioner more comfortably, low in noise and energy-saving.
The preset power for the air conditioner to operate in the low power continuous operation mode is 100W to 1200W, for example, 500W. After entering the low power continuous operation state, the air conditioner will continuously operate in a low power consumption state unless a special condition such as a control instruction of a user is received.
For a power comparison of high power short run and low power continuous run, see the experimental data in the following table:
according to experimental data, under the conditions that the environment temperature is the same, the testing time is the same, the room area is the same, and the indoor temperature is maintained to be the same, the energy consumption of the conventional mode is larger than that of the low-power-consumption continuous working mode. Therefore, the low power continuous operation mode of the air conditioner saves energy compared with the conventional operation mode.
Referring to fig. 1 and 2, the present invention provides a control method of an air conditioner, including the steps of:
s100, detecting the number of people in the room in the low-power continuous operation mode of the air conditioner, and setting the number as a first number
The air conditioner is controlled to operate between 100W and 1500W, and is controlled to operate for a long time (more than 24 hours). In this mode, there are various ways to detect the number of people in the room, such as detecting by an infrared detection device, or capturing an image by an image capturing apparatus (such as a camera), and then detecting the number of people by analyzing the result of the image capturing. The number of people detected for the first time is counted as the first number of people.
S200, detecting the number of people in the room after the preset time is up, and setting the number of people as a second number of people;
and after the preset time, detecting the number of people in the room again, and recording the number of people in the room detected again as a second number of people. The predetermined time period may be several seconds, such as 3 seconds, several minutes, such as 3 minutes, more than ten minutes, or twenty minutes. The preset time is actually the period of detecting the number of people, if the first number of people is zero, the detection is carried out again after the time period, and when the number of people is still zero, the operation of the air conditioner is unchanged; when the number of people detected after the time period is not zero, the air conditioner adjusts according to the requirement, for example, the rotating speed of the wind wheel is reduced, so that the indoor noise is reduced.
S300, comparing the first number of people with the second number of people, and adjusting the working frequency of the compressor and the rotating speed of the wind wheel according to the comparison result to save energy or reduce noise
According to the comparison result of the first number of people and the second number of people, the number of specific people is combined, and according to different purposes, many different controls can be made. As a simple example, when a person is changed from no person to a person in a room, that is, when a user enters the room, the rotation speed of the wind wheel is reduced for noise reduction, and the compression frequency is increased for improving the air conditioning capability of the air conditioner (increasing the output of cold energy or heat energy); when all users go out of the room, namely the first number of people is larger than zero and the second number of people is equal to zero, in order to save energy and reduce the frequency of a compressor, and in order to keep the indoor temperature, the rotating speed of a wind wheel is increased so as to output cold energy or heat energy on a heat exchanger from an air conditioner quickly; when the number of people in the room reaches a certain number, for example, 5 people or more, the increase of the compression frequency can be reduced appropriately for saving energy, and the rotating speed of the wind wheel can be reduced appropriately for satisfying the output of cold energy or heat energy.
In this embodiment, in the low power continuous operation mode of the air conditioner, the number of people in the room is first detected and set as the first number of people; detecting the number of people in the room after the preset time length, and setting the number as a second number; then, comparing the first number of people with the second number of people, and adjusting the working frequency of the compressor and the rotating speed of the wind wheel according to the comparison result to save energy or reduce noise; the air conditioner runs for a long time, so that walls, furniture and the like in a room are kept in a range close to the temperature required by a user, when a new temperature requirement of the user is detected and the temperature is adjusted, the amplitude required to be adjusted is very small, meanwhile, because the temperature of articles in the room is slightly different from the required temperature, the room temperature can be adjusted and controlled by very little cold energy or heat energy, the requirement of the user can be met in a short time, and further, the energy loss caused by high-power work of the air conditioner is avoided; because the temperature in the room is maintained to be close to the temperature required by the user, the user can feel very comfortable immediately after entering the room, and the scheme saves energy and greatly improves the comfort level of the user; meanwhile, the user can experience a comfortable state whenever entering a room, the phenomenon that the user can feel comfortable after waiting for a long time is avoided, the phenomenon that the user forgets to turn on the air conditioner before returning home is also avoided, the convenience of using the air conditioner by the user is improved, and the use of the air conditioner is more humanized;
just because the amplitude of the temperature to be regulated is very small, the air conditioner can meet the output requirements of increasing cold energy and heat energy of a user, and simultaneously reduces the rotating speed of the wind wheel to realize noise reduction, namely, the high unification of noise reduction and capacity increasing output (temperature regulation) is realized, so that when the user enters a room, the comfortable temperature can be enjoyed, and simultaneously, the interference of noise is avoided; when a user leaves a room, the rotating speed of the wind wheel is increased, the working frequency of the compressor is reduced, the temperature in the room can be maintained, energy can be saved, and high unification of energy conservation and capacity output (heat preservation) is realized; the whole scheme realizes high unification of noise reduction, energy saving and capacity output of the air conditioner, and is beneficial to quieter, energy saving and comfortable use of the air conditioner by a user.
When getting into the room for the user, obtain the low noise, the suitable environment of temperature, satisfy energy output when reducing indoor noise, compare first number and second number, adjust compressor operating frequency and wind wheel rotational speed according to the comparison result and specifically include with energy-conservation or the step of making an uproar that falls:
when the first number of people is zero and the second number of people is more than or equal to 1, the rotating speed of the wind wheel is reduced and the working frequency of the compressor is improved.
How to achieve low noise and uniformity of capacity output is explained in the following in a heating mode. When a user just enters a room, the temperature is required to be adjusted to the temperature required by the user, and high noise is not expected, at the moment, the rotating speed of the wind wheel is reduced to reduce noise, and the frequency of the compressor is increased to increase the output of heat energy. After the adjustment, although the wind speed is reduced, the heat energy input in unit time is increased, so that the indoor temperature can be effectively improved. It is worth to be noted that, because the rotating speed of the wind wheel is reduced, the wind speed is reduced, which is not beneficial to quickly conveying the air after heat exchange of the heat exchanger to the room, so that the lifting amount and the lifting speed of the room temperature are limited, but because the temperature required to be lifted in the room is not much in the low-power continuous working mode, even if the rotating speed of the wind wheel is reduced, the temperature can be quickly raised to the temperature required by the user by increasing the frequency of the compressor. Namely, the unification of noise reduction and temperature adjustment is realized.
In order to enable the users to completely leave the room, energy output is met while energy saving is achieved, a first number of people is compared with a second number of people, and the steps of adjusting the working frequency of the compressor and the rotating speed of the wind wheel according to the comparison result so as to save energy or reduce noise specifically comprise the following steps:
when the first number of people is larger than or equal to 1 and the second number of people is zero, the working frequency of the compressor is reduced and the rotating speed of the wind wheel is increased.
How to achieve the unification of energy saving and capacity output is explained in the heating mode below. When the user leaves the room completely, the temperature is required to be adjusted to the heat preservation temperature, and the noise is not required to be noticed, at the moment, the rotating speed of the wind wheel is increased to increase the wind speed, so that the air after heat exchange of the heat exchanger is rapidly conveyed to the room, and the frequency of the compressor is reduced to save energy. After the adjustment, although the frequency of the compressor is reduced, the heat energy input in unit time is reduced due to the increase of the wind speed, and the smaller heat energy can still effectively output energy, so that the indoor temperature can be effectively maintained. It is worth saying that the increase of the rotating speed of the wind wheel and the increase of the wind speed are beneficial to rapidly conveying the air after the heat exchange of the heat exchanger to the room, so that a certain heat energy conveying amount can be ensured even if the working frequency of the compressor is reduced, and the indoor temperature can be effectively maintained; therefore, even under the condition that the frequency of the compressor is reduced, the temperature can be effectively kept at the temperature required by a user by increasing the rotating speed of the wind wheel. Namely, the unification of energy conservation and temperature regulation is realized.
In order to realize energy saving and simultaneously meet energy output, the method comprises the following steps of comparing a first number of people with a second number of people, and adjusting the working frequency of a compressor and the rotating speed of a wind wheel according to a comparison result so as to save energy or reduce noise:
comparing the second number of people with a first preset number of people; wherein the second number of people is greater than the first number of people;
when the second number of people is larger than or equal to the first preset number of people, calculating and comparing a first difference value between the second number of people and the first number of people with a first preset difference value;
and when the first difference is larger than or equal to a first preset difference, reducing the working frequency of the compressor and increasing the rotating speed of the wind wheel.
How to achieve the unification of energy saving and capacity output is explained in the heating mode below. When the number of people in the room increases and the increasing range reaches a first preset difference value, the number of people in the room is considered to be enough, and at the moment, the noise generated by the rotation of the wind wheel does not influence the normal life of the user. At the moment, the rotating speed of the fan can be properly increased to increase the conveying of the gas after heat exchange, and meanwhile, the working frequency of the compressor can be reduced for energy conservation, so that the unification of energy conservation and capacity output is realized. The first predetermined number of people is for example 3 to 5, and the first predetermined difference is for example 2 to 4. At least one person originally exists in the room, then two or more persons enter at the same time, and the air conditioner judges that the noise generated by slightly increasing the rotating speed of the wind wheel does not influence the daily activities of the user under the condition.
In order not to influence the temperature adjusting capability of the air conditioner, the method further comprises the following steps after the step of reducing the working frequency of the compressor and increasing the rotating speed of the wind wheel when the first difference is greater than or equal to a first preset difference:
comparing the second number of people with a second preset number of people, wherein the second preset number of people is more than the first preset number of people;
and when the second number of people is more than or equal to a second preset number of people, the frequency of the compressor is increased, and the rotating speed of the wind wheel is maintained or increased.
The following description will be made by taking a heating mode as an example. When the second number of people reaches a certain number, for example, 6 or more, the air conditioner needs to increase the frequency of the compressor to increase the temperature adjusting capability in order to ensure that the indoor temperature meets the user's demand. When the rotating speed of the fan is increased to a certain rotating speed, the energy required for continuously increasing the rotating speed is larger than the energy consumed by increasing the frequency of the compressor from a lower frequency to a required frequency, namely, the output of the energy can be greatly increased by increasing the frequency of the compressor, and meanwhile, compared with the effect of achieving the same energy output, the energy required by increasing the rotating speed of the fan again is increased, and the energy required by increasing the frequency of the compressor is less. When the number of people reaches more, such as more than 10 people, the rotating speed of the fan needs to be increased simultaneously to meet the adjustment of the air temperature.
In order to save energy, reduce noise and temperature control and take into account simultaneously, compare first number of people and second number of people, according to the comparison result adjust compressor operating frequency and wind wheel rotational speed in order to save energy or reduce noise the step specifically includes:
comparing the second number of people with a second preset number of people; wherein the first number is greater than the second number;
when the second number of people is less than or equal to a second preset number of people, calculating a second difference value between the first number of people and the second number of people, and comparing the second difference value with the second preset difference value;
and when the second difference is larger than or equal to a second preset difference, reducing the rotating speed of the wind wheel.
The following description will be made by taking a heating mode as an example. In the heating mode, part of users in the room leave the room, the number of people in the room is reduced, so that the energy requirement in the room is reduced, and at the moment, the working frequency of the compressor or the rotating speed of the wind wheel can be reduced for energy conservation. The rotational speed of the wind wheel may be reduced in order to reduce noise in the room. Therefore, when the number of people in a room is reduced, energy can be saved and noise can be reduced by reducing the rotating speed of the wind wheel. After some users leave the room, the number of people in the room is reduced, so that the number of people remaining in the room is small (smaller than or equal to a second preset number of people). The second predetermined difference is 2-5 persons, and the second predetermined number is 2-4 persons. That is, after some users leave, the daily life of the users in the room is affected by the noise generated by the fan.
In order to save energy, the step of reducing the rotation speed of the wind wheel when the second difference is greater than or equal to a second preset difference is further followed by:
comparing the second number of people with a third preset number of people, wherein the third preset number of people is smaller than the second preset number of people;
and when the second number of people is less than or equal to a third preset number of people, reducing the working frequency of the compressor.
When the number of users in the room is further reduced, the required cold energy or heat energy in the room is reduced again, and in order to save energy and reduce energy consumption, the working frequency of the compressor is reduced. The third predetermined number of people is 1 to 3. When the second number of people is less than or equal to the third preset number of people, the working frequency of the compressor is reduced, so that the comfort (comfortable temperature and low noise) of the user in the whole using process can be ensured, and the reasonable utilization of energy is fully considered.
In order to more reasonably control the operation of the air conditioner so as to improve the utilization rate of energy, the control method of the air conditioner further comprises the following steps:
s400, acquiring outdoor environment temperature
Specifically, in this embodiment, there are various ways to obtain the outdoor ambient temperature, and the outdoor ambient temperature may be detected directly through the temperature sensor, or may be obtained through connecting to the internet to obtain a local weather forecast and obtain the current outdoor ambient temperature from the weather forecast.
S500, acquiring a proportional coefficient corresponding to the current environment temperature according to the current environment temperature;
and establishing a mapping table between the current environment temperature and the proportionality coefficient, wherein different environment temperatures correspond to different proportionality coefficients, and when the current environment temperature is obtained, the proportionality coefficient is directly obtained from the mapping table.
Regarding the magnitude of the proportionality coefficient, in some embodiments, the greater the maximum value of the zone temperature (during cooling), or the smaller the minimum value of the zone temperature (during heating), the greater the proportionality coefficient, and vice versa. The temperature of the preset area is-6-16 ℃, and the ambient temperature is a proportionality coefficient corresponding to-7 ℃ and is smaller than a proportionality coefficient corresponding to-8 ℃; the proportional coefficient corresponding to the environment temperature of 17 ℃ is smaller than the proportional coefficient corresponding to the environment temperature of 18 ℃.
Of course, in some embodiments, by comparing the ambient temperature with the target temperature for use, the scaling factor is larger when the ambient temperature is greater in difference from the target temperature, and the scaling factor is smaller when the ambient temperature is smaller in difference from the target temperature. The area temperature is-6 ℃ to 16 ℃ as an example, the target temperature is 18 ℃ as an example, and the proportionality coefficient corresponding to the environment temperature of 14 ℃ is greater than the proportionality coefficient corresponding to the environment temperature of 17 ℃.
In still other embodiments, the scaling factor is smaller for ambient temperatures closer to the middle of the zone temperature and the scaling factor is larger for values closer to the two ends of the zone temperature.
Of course, in the heating mode, when the ambient temperature is within the zone temperature, the closer to the maximum value, the smaller the proportionality coefficient. The area temperature is taken as an example of-6 ℃ to 16 ℃, and the proportionality coefficient corresponding to the environment temperature of 12 ℃ is greater than the proportionality coefficient corresponding to the environment temperature of 16 ℃.
S600, adjusting the running power of the air conditioner to the product of the preset power and the proportionality coefficient.
And after the proportionality coefficient is obtained, adjusting the running power of the air conditioner to the product of the preset power and the proportionality coefficient. The running power of the air conditioner conforms to the following rules:
the proportionality coefficient is expressed by a, a is larger than zero and less than or equal to 1; the preset power is 100W to 1200W. The running power of the air conditioner at the moment meets the following requirements:
Qoperation of＝a*QPreset of
Wherein Q isOperation ofActual output power, Q, of air conditionerPreset ofA is a proportionality coefficient for the preset power.
The operation power of the air conditioner is adjusted to the product of the preset power and the proportionality coefficient.
In order to make the room temperature meet the requirements of the user more quickly and accurately, the power consumption of the air conditioner needs to be calculated and controlled more accurately, and the step of adjusting the operating power of the air conditioner to the product of the preset power and the proportionality coefficient specifically includes:
acquiring a target maintaining temperature;
the target maintenance temperature is an indoor temperature value set by a user, and the operation of the air conditioner is aimed at maintaining the indoor temperature at the target maintenance temperature (allowing up-down deviation). The user can set according to own needs, also can set according to current ambient temperature, and the user will consider considering comfortable and energy-conserving and select the target to maintain the temperature when setting.
Acquiring first compensation power of preset power according to the target maintenance temperature;
and establishing a mapping table between the target maintaining temperature and the first compensation power, wherein different target maintaining temperatures correspond to different first compensation powers, and after the target maintaining temperature is obtained, directly obtaining the first compensation power from the mapping table. In the heating mode, the higher the target maintaining temperature is, the larger the first compensation power is, otherwise, the smaller the first compensation power is; in the cooling mode, the lower the target maintaining temperature is, the larger the first compensation power is, and vice versa. Of course, in some embodiments, the first compensation power is also related to the ambient temperature, the smaller the difference between the ambient temperature and the target maintenance temperature, the smaller the first compensation power b1, and the larger the difference between the ambient temperature and the target maintenance temperature, the larger the first compensation power b 1. Of course, in some embodiments, the first compensation power b1 may also be associated with a model, and different models correspond to different first compensation values, and the larger the power of the model is, the larger the first compensation value is.
