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 the pipe wall temperature of a refrigerant pipe of an indoor heat exchanger of an air conditioner;
in this embodiment, there are various ways to obtain the wall temperature of the refrigerant pipe, for example, directly detect the wall temperature through a temperature sensor, or call the wall temperature from a main control module of the air conditioner (the main control module obtains the wall temperature and maintains the obtained wall temperature). The wall temperature represents the temperature of the refrigerant in the refrigerant tube, and corresponds to the operating mode (cooling or heating) of the air conditioner and the power frequency of the compressor. The higher or lower the temperature of the pipe wall is, the higher or lower the temperature of the refrigerant is, the compressor is in a high-frequency working state, the air conditioner is in a high energy consumption state, and meanwhile, the difference between the current indoor temperature and the target temperature required by a user is larger.
S300, acquiring a temperature compensation value according to the temperature of the pipe wall
And establishing a mapping table between the pipe wall temperature and the temperature compensation value, wherein different pipe wall temperatures correspond to different temperature compensation values, and when the pipe wall temperature is obtained, the temperature compensation value is directly obtained from the mapping table. The higher the temperature of the pipe wall (heating mode) or the lower the temperature of the pipe wall (cooling mode), the larger the absolute value of the temperature compensation value (the temperature compensation value is positive during heating and negative during cooling); the lower the temperature of the pipe wall (heating mode) or the higher the temperature (cooling mode), the smaller the absolute value of the temperature compensation value (positive temperature compensation value during heating and negative temperature compensation value during cooling).
Of course, in some embodiments, the temperature compensation value and the wall temperature may also conform to a piecewise function, that is, the temperature compensation value is the same when the wall temperature is within a predetermined range, and the temperature compensation value increases with the increase of the wall temperature in the heating mode as an example.
S400, compensating the temperature compensation value to the running temperature of the air conditioner
And supplementing the temperature compensation value obtained according to the temperature of the pipe wall to the operating temperature of the air conditioner. In this embodiment, there are two compensation methods, one is to compensate the detected temperature of the air conditioner, that is, to add a temperature compensation value on the basis of the detected indoor ambient temperature, taking heating as an example, the detected current ambient temperature is 16 ℃, the obtained temperature compensation value is 1 ℃, and at this time, the indoor ambient temperature is considered to be 15 ℃.
In another way, the temperature compensation value is directly added to the target temperature, taking heating as an example, the obtained target temperature required by the user is 20 ℃, the temperature compensation value is 1 ℃, at this time, the target temperature of the user is considered to be 21 ℃, and the air conditioner is operated according to the target temperature of 21 ℃.
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 acquiring the pipe wall temperature of a refrigerant pipe of the indoor heat exchanger of the air conditioner; then, acquiring a temperature compensation value according to the temperature of the pipe wall, and compensating the temperature compensation value to the operating temperature of the air conditioner; 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, when the new temperature requirement of the user is detected and the temperature is adjusted, the amplitude required to be adjusted is very small, the temperature compensation value required by temperature adjustment is small, and the corresponding temperature compensation value can be accurately obtained only by considering the temperature of the pipe wall; when the traditional air conditioner works, the calculation of the temperature compensation value is complex due to the short running time of the air conditioner, and the air conditioner is not suitable for the air conditioner which runs continuously at low power; therefore, the technical scheme of the invention can improve the accuracy of the temperature compensation value, and the temperature compensation value is not too high due to the very accurate calculation of the temperature compensation value, so that the energy loss is reduced, and the purpose of energy conservation is achieved;
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 the following, how the pipe temperature corresponds to the compensation value is described in detail, and the heating mode is described, it is understood that the cooling mode corresponds to the heating mode.
Comparing the pipe wall temperature with a first preset pipe temperature in order to more accurately obtain a temperature compensation value; the first preset pipe temperature is 23-25 ℃;
there are many ways to compare the calculated or detected wall temperature with the first predetermined wall temperature, for example, by means of a comparison circuit. The first preset pipe temperature is obtained through careful research and deep analysis by the applicant, and is 23-25 ℃, taking 24 ℃ as an example. Of course, in some other embodiments, the first preset tube temperature may be fine-tuned according to actual conditions.
When the temperature of the pipe wall is less than or equal to a first preset pipe temperature, the temperature compensation value is zero;
when the temperature of the pipe wall is less than or equal to the first preset pipe temperature, the working frequency of the compressor is low at the moment, and the air conditioner runs for a sufficient time in the low-power continuous working mode, so that the temperature of furniture, walls and the like in a room is equivalent to the temperature of air, the temperature of the air in the room is not layered, and the temperature difference of the air from the ceiling to the bottom plate is very small and is within an allowable error range; in this range, the human body hardly feels the temperature difference. At this time, the temperature compensation value is set to zero, and the temperature detected by the air conditioner is the real temperature of each position in the room at this time because the temperature difference of air, furniture, walls and the like in the room is very small, so that the output temperature of the air conditioner does not need to be compensated any more.
In this embodiment, when the pipe wall temperature is greater than or equal to the first preset pipe temperature, the temperature compensation value is set to zero, so that the temperature compensation value of the low-power continuous-operation air conditioner is different from that of the conventional air conditioner, and the difference is due to the fact that the operation mode of the air conditioner in the application is different from that of the conventional air conditioner in nature, and the temperature compensation rule is more suitable for the low-power continuous-operation air conditioner of the present invention by adjusting the temperature compensation rule, so that the temperature compensation value of the air conditioner is more accurate, the accuracy of adjusting the temperature of the air conditioner is improved, excessive temperature compensation is avoided, and energy saving is facilitated.

The second preset pipe temperature is obtained through careful research and deep analysis by the applicant, and is 26-30 ℃, taking 28 ℃ as an example. Of course, in some other embodiments, the second preset tube temperature may be fine-tuned according to actual conditions.
And when the pipe wall temperature is less than or equal to a second preset pipe temperature and greater than the first preset pipe temperature, the absolute value of the temperature compensation value is greater than or equal to 0.5 and less than or equal to 1.
When the temperature of the pipe wall is less than or equal to the second preset pipe temperature, the working frequency of the compressor is low at the moment, and the air conditioner runs for a long time in a low-power continuous working mode, so that the temperature difference between the temperature of furniture, walls and the like in a room and the temperature of air is not large, the temperature stratification of the air in the room is not obvious, but the temperature difference of the air from a ceiling to a bottom plate is small and is within an allowable error range; within this range, the human body can feel the temperature difference. At this time, the temperature compensation value is set to [0.5, 1], and the temperature difference between the air in the room, the furniture, the wall and the like is small, so that the difference between the temperature detected by the air conditioner and the real temperature of each position in the room is small, and the compensation value of the output temperature of the air conditioner is also small. When the temperature of the pipe wall is less than or equal to the second preset pipe temperature and greater than the first preset pipe temperature, the air temperature compensation value is adjusted to [0.5, 1], so that the accuracy of temperature adjustment is improved. In the cooling mode, the air compensation value is [ -1, -0.5 ].
In the embodiment, when the temperature of the pipe wall is less than or equal to the second preset pipe temperature, the temperature compensation value is set to [0.5, 1], so that the temperature compensation value of the low-power continuous working air conditioner is different from that of the traditional air conditioner, and the difference is caused by the fact that the operation mode of the air conditioner in the application is different from that of the traditional operation mode essentially, and the temperature compensation rule is more suitable for the low-power continuous working air conditioner provided by the invention through adjusting the temperature compensation rule, so that the temperature compensation value of the air conditioner is more accurate, the accuracy of adjusting the temperature of the air conditioner is improved, excessive temperature compensation is avoided, and energy conservation is facilitated.
