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-consumption continuous operation mode, because the temperature of indoor furniture, walls and the like is equivalent to the temperature of indoor air after long-time operation, the temperature from the ceiling to the floor of a room is equivalent, and no temperature stratification exists, the temperature to be compensated is very small, and when the operation time reaches a certain time, the temperature compensation value can even be set to zero; in the use process of the existing air conditioner, the difference between the temperature of the wall and furniture in a room and the temperature of air is large due to the limited starting time, the air temperature between a ceiling and a floor is obviously layered, and at the moment, the temperature difference in the room is large, so that the temperature compensation value required by the operation of the air conditioner is large; according to the analysis, the temperature compensation is analyzed and controlled aiming at the air conditioner with low power consumption and continuous operation, so that the temperature compensation value of the air conditioner can be accurate in a new temperature compensation mode, and the precision of the air temperature regulation of the air conditioner is improved.
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 traditional 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 traditional operation mode.
Referring to fig. 1 and 2, the present invention provides a control method of an air conditioner, including the steps of:
s100, controlling the running power of the air conditioner to be 100-1500W so as to enable the air conditioner to run in a low-power continuous running mode;
specifically, in this embodiment, the operation power of the air conditioner is controlled to be 100W to 1500W, so that the air conditioner operates in the low power continuous operation mode. The air conditioner continuously operates for 24 hours or more at preset power, and the preset power is 100W-1200W. In some embodiments, the actual output power of the air conditioner is the preset power plus a compensation value, the compensation value is related to the environment temperature, the target temperature and the machine type, and the total output power is 100W-1500W.
S200, acquiring a target temperature and a current temperature, and maintaining the target temperature for t, wherein t is greater than or equal to 24 hours;
the target temperature can be obtained in various ways, and the target temperature sent by the user can be directly received or obtained from a main control module of the air conditioner. The current temperature can be directly detected by a temperature sensor, or can be obtained by searching weather forecast through the Internet. In the low-power continuous operation mode, the temperature in the room is maintained after a certain time period, i.e. the air conditioner needs to be operated after the time period t, so that the temperature in the room can be really maintained at the target temperature.
S300, comparing the target temperature with the current temperature; and when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference delta T, increasing the frequency of the compressor and/or increasing the rotating speed of the indoor fan so as to enable the temperature difference between the target temperature and the current temperature to be less than or equal to the preset temperature difference delta T.
When the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference Δ T, it indicates that the current indoor temperature is lower than the preset holding temperature, and if the user enters the room at this time, the user cannot feel the best comfort. At this moment, the frequency of the compressor needs to be increased and/or the rotating speed of the indoor fan needs to be increased so as to quickly adjust the indoor temperature, so that the temperature difference between the target temperature and the current temperature is smaller than or equal to the preset temperature difference delta T, and a user can feel comfortable when entering the room.
Wherein, the delta T is 4-10 ℃, for example 5 ℃, and the target temperature is 18-25 ℃, for example 20 ℃.
In this embodiment, firstly, the operation power of the air conditioner is controlled to be 100W-1500W, so that the air conditioner operates in the low-power continuous operation mode; then obtaining the target temperature and the current temperature, wherein the time for maintaining the target temperature is t, and t is greater than or equal to 24 hours; then, comparing the target temperature with the current temperature, and when the temperature difference between the target temperature and the current temperature is greater than a preset temperature difference delta T, increasing the frequency of a compressor and/or increasing the rotating speed of an indoor fan so as to enable the temperature difference between the target temperature and the current temperature to be less than or equal to the preset temperature difference delta T; after the low-power continuous operation air conditioner is continuously operated for the working time t, the indoor temperature is maintained at the target temperature, and when the difference between the indoor temperature and the target temperature is large, the power of a compressor and the rotating speed of an air wheel are timely adjusted to rapidly adjust the room temperature;
because the air conditioner runs for a long time, walls, furniture and the like in a room are kept in a range close to the temperature required by a user, and when the new temperature requirement of the user is detected and the temperature is adjusted, the adjustment range is very small; meanwhile, as the difference between the temperature of the articles in the room and the required temperature is small, the room temperature can be regulated and controlled by very little cold energy or heat energy, and the requirement of a user can be met in a short time, so that the energy loss caused by the 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 the user for using the air conditioner is improved, and the air conditioner is more humanized to use.
In order to take energy saving and maintain indoor temperature into consideration, when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference Δ T, the step of increasing the frequency of the compressor and/or increasing the rotating speed of the indoor fan so that the temperature difference between the target temperature and the current temperature is less than or equal to the preset temperature difference Δ T includes:
detecting the number of people in the room;
there are many ways to detect whether there is a person in a room, for example, detecting by an infrared sensor, or collecting images by a camera device, and then analyzing the collected images to finally determine the number of people in the room.
When the number of people in the room is zero, increasing the rotating speed of the indoor fan to a first preset rotating speed;
when no person is in the room, the problem of noise does not need to be considered, and at the moment, the output of cold energy or heat energy can be increased by increasing the rotating speed of the indoor fan. It is worth mentioning that when the rotating speed of the indoor fan is increased, the energy on the indoor heat exchanger can be rapidly dissipated indoors, so that the adjustment of the indoor temperature is accelerated.
Acquiring a current temperature, and comparing the current temperature with a target temperature;
after the rotating speed of the fan is adjusted to the first preset rotating speed, the current temperature and the target temperature are compared, and the energy (cold energy or heat energy) output capacity of the air conditioner is adjusted according to a new comparison result.
And when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference delta T, increasing the frequency of the compressor to a first preset frequency so that the temperature difference between the target temperature and the current temperature is less than or equal to the preset temperature difference delta T. After the rotating speed of the fan of the indoor unit is adjusted to the first preset rotating speed, the requirement of a user cannot be met, and at the moment, the output of energy is improved by improving the power of the compressor and increasing the output of cold energy or heat energy. It is worth mentioning that when the rotating speed of the fan is increased to a certain value and then is increased, the energy consumption is greatly increased, and the energy required by the compressor is reduced when the compressor is increased from a lower frequency to an intermediate frequency, that is, the energy output is increased by increasing the frequency of the compressor, so that the energy-saving effect is better than that of increasing the rotating speed of the fan; on the other hand, when the frequency of the compressor is not changed, and the rotating speed of the fan is raised again after reaching the first preset rotating speed, the effect of increasing the energy output is not great, because the energy which can be exchanged in unit time on the heat exchanger (positively correlated with the frequency of the compressor, the higher the frequency of the compressor, the larger the temperature difference between the indoor heat exchanger and the air) is limited, and at the moment, if the energy which can be exchanged in unit time on the heat exchanger (realized by increasing the frequency of the compressor) is increased, the output of the energy (cold energy or heat energy) can be greatly increased. Therefore, when the indoor fan speed reaches the first preset speed, the energy output is preferentially increased by increasing the compressor frequency.
When the temperature difference between the target temperature and the current temperature is smaller than the preset temperature difference delta T, the frequency of the compressor and the rotating speed of the indoor fan do not need to be adjusted, and the current working parameters of the air conditioner are kept.
Similarly, after the working frequency of the compressor is adjusted to the first preset frequency, when the temperature difference between the current temperature and the target temperature still cannot be controlled within Δ T, the rotating speed of the indoor fan needs to be increased again instead of continuously increasing the frequency of the compressor.
In order to further save energy in the process of maintaining the indoor temperature, when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference Δ T, the step of increasing the frequency of the compressor to the first preset frequency so that the temperature difference between the target temperature and the current temperature is less than or equal to the preset temperature difference Δ T includes:
raising the frequency of the compressor to a first preset frequency;
acquiring a current temperature, and comparing the current temperature with a target temperature;
and when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference delta T, increasing the rotating speed of the indoor fan to a second preset rotating speed, wherein the second preset rotating speed is higher than the first preset rotating speed, so that the temperature difference between the target temperature and the current temperature is less than or equal to the preset temperature difference delta T.
In this embodiment, when the operating frequency of the compressor is adjusted to the first preset frequency and the rotating speed of the indoor fan is adjusted to the first preset rotating speed, if the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference Δ T, the rotating speed of the indoor fan is increased to the second preset rotating speed, so as to further increase the output of energy. At this moment, the rotating speed of the fan is increased, so that the working frequency of the compressor is continuously increased, energy is saved, and meanwhile, the output of energy can be effectively increased.
In order to further improve the accuracy of adjusting the rotating speed of the indoor fan, the step of increasing the rotating speed of the indoor fan to a second preset rotating speed comprises the following steps:
acquiring an outdoor environment temperature T4;
the mode of obtaining the outdoor environment temperature has various modes, and the outdoor environment temperature can be detected through a temperature sensor or directly obtained from a main control module of the air conditioner. The main control module can acquire various modes, and detection is carried out through a sensor or searching is carried out through the Internet.
Calculating a second preset rotating speed N according to the outdoor environment temperature T4, wherein N is equal to the rotating speed N of the outdoor unit fan and is equal to the natural algebra ㏑ (T) of the outdoor environment temperature T and a first proportional coefficient a in the heating mode1The inverse of the product of (a) and then compensated with the first speed (b)1And (4) summing.
The rotating speed rate of the wind wheel of the outdoor unit of the air conditioner meets the following rules:
first scale factor is represented by a1Is shown as a1The size of (1) is 600-660, for example 638; first speed compensation b11950-2000, 1978 for example;
the running rotating speed of the fan of the outdoor unit of the air conditioner meets the following requirements:
N＝-a1*㏑(T)+b1
wherein, N is the target rotation speed of the outdoor unit fan of the air conditioner, T is the outdoor environment temperature, and a1 is the proportionality coefficient.
Wherein the first slew rate compensation may be associated with one or more of a model, an outdoor ambient temperature, and a target maintenance temperature. Of course, a mapping relationship between the first rotation speed compensation and the above factors may also be stored in the air conditioner, and the corresponding first rotation speed compensation may be obtained according to one or more of the model, the outdoor ambient temperature, and the target maintenance temperature.
Referring to fig. 3, the following table shows the correspondence between the outdoor environment temperature and the outdoor unit fan rotation speed
| Outdoor ambient temperature (. degree. C.) | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 |
| Outdoor fan speed (r/m) | 209 | 250 | 294 | 342 | 393 | 448 | 509 | 576 | 651 |
In the cooling mode, the rotating speed N of the outdoor unit fan is equal to the natural algebra ㏑ (T) and the second proportionality coefficient a of the outdoor environment temperature T2The product of (a) and a second rotational speed compensation b2The difference between them; adjusting the rotating speed of the indoor fan to a second preset rotating speed N;
the rotating speed rate of the wind wheel of the outdoor unit of the air conditioner meets the following rules:
third scale factor is represented by a2Is shown as a2The size of (a) is 1000-1500, take 1344 as an example; third speed compensation b2The size of (A) is 4000-4150, taking 4076 as an example;
the running rotating speed of the fan of the outdoor unit of the air conditioner meets the following requirements:
N＝a2*㏑(T)-b2
wherein, N is the target rotation speed of the outdoor unit fan of the air conditioner, T is the outdoor environment temperature, and a2 is the proportionality coefficient.
Wherein the third speed compensation may be associated with one or more of model, outdoor ambient temperature, and target maintenance temperature. Of course, a mapping relationship between the third rotational speed compensation and the above factors may also be stored in the air conditioner, and the corresponding third rotational speed compensation may be obtained according to one or more of the model, the outdoor environment temperature, and the target maintenance temperature.
Referring to fig. 4, the following table shows the correspondence between the outdoor ambient temperature and the outdoor unit fan rotation speed
| Outdoor ambient temperature (. degree. C.) | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 |
| Outdoor fan speed (r/m) | 164 | 218 | 270 | 321 | 369 | 416 | 461 | 505 | 547 |
In the process of low-power continuous operation of the air conditioner, when a user exists in a room, the problem of noise needs to be considered besides energy conservation, namely when the user exists in the room, the energy output of the air conditioner is adjusted by increasing the frequency of a compressor in priority, and then the energy output of the air conditioner is increased by increasing the rotating speed of a wind wheel in consideration.
When the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference delta T, the step of increasing the frequency of the compressor and/or increasing the rotating speed of the indoor fan to enable the temperature difference between the target temperature and the current temperature to be less than or equal to the preset temperature difference delta T comprises the following steps:
detecting the number of people in the room;
there are various ways to detect the number of people in a 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 image capturing result.
When the number of people in the room is more than or equal to 1 and less than the first preset number of people, the frequency of the compressor is increased to a second preset frequency, so that the temperature difference between the target temperature and the current temperature is less than or equal to a preset temperature difference delta T.
How to achieve low noise and uniformity of capacity output is explained in the following in a heating mode. When a user enters a room or has a user in the room, the temperature needs to be adjusted to the temperature required by the user, and the noise is not expected to be large, the frequency of the compressor is preferentially increased to increase the output of the heat energy. After the adjustment, the heat energy input in unit time is increased, so that the heat energy can be rapidly increased. Since the number of users is less than the first predetermined number (the first predetermined number is 4-6, for example, 5), it is indicated that the number of users is small, and a certain noise is generated by the high rotation speed of the indoor fan.
At the moment, the rotating speed of the wind wheel is kept unchanged or the rotating speed of the wind wheel is reduced to reduce noise, and after the adjustment is carried out, 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.
When the number of people in the room continues to increase and is greater than the first preset number of people, the number of people in the room is more, the daily activities of the user are not influenced by the sound generated by the rotation of the indoor fan, and at the moment, energy conservation and rapid temperature adjustment can be preferentially considered. Namely, the rotating speed of the indoor wind wheel is increased preferentially, and then the frequency of the compressor is increased.
Further comprising, after the step of detecting the number of people in the room:
when the number of people in the room is greater than or equal to a first preset number of people, increasing the rotating speed of the indoor fan to a third preset rotating speed;
acquiring a current temperature, and comparing the current temperature with a target temperature;
and when the temperature difference between the target temperature and the current temperature is greater than the preset temperature difference delta T, increasing the frequency of the compressor to a third preset frequency so that the temperature difference between the target temperature and the current temperature is less than or equal to the preset temperature difference delta T.
In this embodiment, it is preferable to increase the output of energy by increasing the rotational speed of the indoor fan, and it is preferable to increase the output of energy by increasing the operating frequency of the compressor, so that energy saving is preferable because the noise of the high-speed rotation of the fan does not affect the user, that is, not only energy saving but also daily life of the user, when the number of people is greater than or equal to the first preset number of people.
