After the structure of the air conditioner on-hook is known, the control method of the air conditioner on-hook comprises the following steps:

specifically, in this embodiment, there are various ways to obtain the indoor ambient temperature, and the indoor ambient temperature can be detected directly by the temperature sensor; the temperature sensor can also be connected with other indoor devices with temperature detection functions through a wireless or wired network, and then the current indoor environment temperature is acquired from the devices.
S20, calculating a temperature difference between the indoor temperature and a preset temperature;
the preset temperature is a target temperature set by a user, or the preset temperature is a temperature set according to habits of the user, namely the target temperature of the current operation of the on-hook air conditioner. Since the temperature has positive and negative values, the temperature difference in the present embodiment is taken as an absolute value of the temperature difference for convenience of description. For example, a difference of 2 ℃ between-3 ℃ and-5 ℃ and a difference of 2 ℃ between 3 ℃ and 5 ℃.
S30, when the absolute value of the temperature difference is less than or equal to the preset temperature difference, closing the first control valve 710 to close the corresponding first heat exchange unit 211; and/or closing second control valve 720 to close the corresponding second heat exchange unit 221.
In this embodiment, when the absolute value of the temperature difference is smaller than or equal to the preset temperature difference, it indicates that the difference between the current indoor temperature and the target temperature is already very small. At this time, it is considered to reduce the output load of the on-hook air conditioner, and slow down or stop the continuous temperature rise or decrease so as to maintain the current indoor temperature. In the process, the working frequency of the compressor can be reduced, and the working efficiency of the first heat exchanger and the second heat exchanger can be reduced, or one of the heat exchangers, part of the first heat exchange unit 211 or the second heat exchange unit 221 can be directly closed. In this embodiment, the first control valve 710 is closed to block a portion of the refrigerant flowing in the first heat exchange unit 211 and/or the second heat exchange unit 221, so as to close a portion of the first heat exchange unit 211 and/or the second heat exchange unit 221, and only a portion of the first heat exchange unit 211 and/or the second heat exchange unit 221 is allowed to operate.
In the embodiment, the technical scheme of the invention includes that the indoor temperature is obtained firstly; then, calculating a temperature difference between the indoor temperature and the preset temperature, and when the absolute value of the temperature difference is less than or equal to the preset temperature difference, closing the first control valve 710 to close the corresponding first heat exchange unit 211; and/or closing the second control valve 720 to close the corresponding second heat exchange unit 221; when part of the first heat exchange units 211 and/or the second heat exchange units 221 are closed, all the refrigerant compressed by the compressor passes through the conducted first heat exchange units 211 and/or second heat exchange units 221, and under the condition that the working frequency of the compressor is certain, the temperature of the conducted first heat exchange units 211 and/or second heat exchange units 221 is higher (in a heating mode) or lower (in a cooling mode) than the temperature of all the heat exchange units when the conducted first heat exchange units 211 and/or second heat exchange units 221 are completely conducted, so that the heat exchange efficiency of the conducted first heat exchange units 211 and/or second heat exchange units 221 is improved; particularly, when the difference between the current indoor temperature and the preset temperature is small, the frequency of the compressor is reduced, only part of the first heat exchange unit 211 and/or the second heat exchange unit 221 is used, the temperature of the conducted first heat exchange unit 211 and/or the conducted second heat exchange unit 221 is not too high or too low, and the heat exchange efficiency of the conducted first heat exchange unit 211 and/or the conducted second heat exchange unit 221 is further improved, so that the air temperature can be quickly adjusted by the on-hook air conditioner.
In order to better control the heat exchange of the first heat exchanger, when the absolute value of the temperature difference is less than or equal to the preset temperature difference, the first control valve 710 is closed to close the corresponding first heat exchange unit 211; and/or the step of closing the second control valve 720 to close the corresponding second heat exchange unit 221 specifically comprises:
when the absolute value of the temperature difference value is less than or equal to the first preset temperature difference and greater than the second preset temperature difference, closing the first number of first control valves 710 and/or the second number of second control valves 720;
when the absolute value of the temperature difference value is less than or equal to a second preset temperature difference, a second number of the first control valve 710 and/or the second control valve 720 is/are closed, wherein the second number is greater than the first number.
Specifically, in the embodiment, the first predetermined temperature difference is, for example, 3 to 5 ℃, and the second predetermined temperature difference is, for example, 1 to 3 ℃. The plurality of first control valves 710 are respectively disposed on the refrigerant pipeline where the first heat exchange unit 211 is located, for example, the first control valves 710 correspond to the heat exchange units one by one. The plurality of second control valves 720 are respectively disposed on the refrigerant pipelines where the second heat exchange units 221 are located, for example, the second control valves 720 and the second heat exchange units 221 are in one-to-one correspondence.
When the absolute value of the temperature difference value is larger than the first preset temperature difference, the indoor temperature is larger than the target temperature, and the compressor and the heat exchanger need to work at high power; when the absolute value of the temperature difference value is less than or equal to the first preset temperature difference and greater than the second preset temperature difference, which indicates that the difference between the indoor temperature and the target temperature is not large, the first control valve 710 and/or the second control valve 720 in the first quantity can be closed first, and the working frequency of the compressor is reduced, so that the output of energy is reduced, and the temperature change speed is slowed down; when the absolute value of the temperature difference value is less than or equal to the second preset temperature difference, which indicates that the indoor temperature is very close to the target temperature, more of the first control valve 710 and/or the second control valve 720 may be closed, i.e., a second number of the first control valve 710 and/or the second control valve 720 may be closed. Therefore, the energy consumption of the air conditioner is gradually reduced, the target temperature is gradually reached, and the temperature of the air conditioner is more accurately controlled.
In order to further improve the utilization rate of energy, the control method of the on-hook air conditioner further comprises the following steps:
acquiring a shutdown instruction of an air conditioner on-hook;
closing a refrigerant outlet of the compressor;
after a preset period of time, the first control valve 710, the second control valve 720 and the compressor are closed.
When the on-hook air conditioner obtains a shutdown instruction, the refrigerant outlet of the compressor is closed first, and the first control valve 710 and the second control valve 720 are closed after a preset time length, so that the refrigerant with higher temperature (heating mode) or lower temperature (cooling mode) in the heat exchanger flows back into the compressor, the temperature of the refrigerant in the compressor is kept, and when the on-hook air conditioner is started next time, the temperature of the refrigerant in the compressor is higher than (heating mode) or lower than (cooling mode) room temperature, so that the compressor can enter an optimal working state more quickly, and the indoor temperature of the on-hook air conditioner can be adjusted better and more quickly. Of course, after the first and second control valves 710 and 720 are closed, the compressor is also closed. It should be noted that, the closing sequence of the first control valve 710, the second control valve 720 and the compressor may be closed at the same time, or the first control valve 710 and the second control valve 720 may be closed before the compressor is closed. The method for closing the refrigerant port of the compressor comprises the following steps that a control valve is directly additionally arranged at the refrigerant outlet of the compressor, and whether the refrigerant in the compressor can flow out or not is controlled by controlling the opening and closing of the control valve; of course, the outflow of condensation in the compressor can also be controlled directly by the four-way valve of the air conditioner.
For more accurate adjustment of the indoor temperature, when the absolute value of the temperature difference is less than or equal to the preset temperature difference, the first control valve 710 is closed to close the corresponding first heat exchange unit 211; and/or, the step of closing the second control valve 720 to close the corresponding second heat exchange unit 221 comprises:
when the absolute value of the temperature difference value is less than or equal to the third preset temperature difference and greater than the fourth preset temperature difference, the operating frequency of the compressor is reduced, and all the first control valves 710 or the second control valves 720 are closed;
and when the absolute value of the temperature difference value is smaller than or equal to the fourth preset temperature difference, closing the first wind wheel or the second wind wheel.
In this embodiment, the third predetermined temperature difference is 1-3 ℃ for example, and the fourth predetermined temperature difference is 0.2-1 ℃ for example. When the absolute value of the temperature difference value is larger than the third preset temperature difference, the indoor temperature is larger than the target temperature, and the compressor and the heat exchanger need to work at high power; when the absolute value of the temperature difference value is smaller than or equal to the third preset temperature difference and larger than the fourth preset temperature difference, the difference between the indoor temperature and the target temperature is smaller, the first control valve 710 can be closed first, the working frequency of the compressor is reduced, the output of energy is reduced, and the first wind wheel continues to work at the moment, so that the energy on the first heat exchanger is output indoors; when the absolute value of the temperature difference value is smaller than or equal to the fourth preset temperature difference value, the indoor temperature is very close to the target temperature, the energy on the first heat exchanger is basically emitted into the air, and then the first wind wheel is turned off.
Or, when the absolute value of the temperature difference value is less than or equal to the third preset temperature difference and greater than the fourth preset temperature difference, which indicates that the difference between the indoor temperature and the target temperature is small, the second control valve 720 may be closed first, and the operating frequency of the compressor is reduced to reduce the output of energy, and the second wind wheel continues to operate to output the energy of the second heat exchanger to the indoor; when the absolute value of the temperature difference value is smaller than or equal to the fourth preset temperature difference, the indoor temperature is very close to the target temperature, the energy on the second heat exchanger is basically emitted into the air, and then the second wind wheel is turned off.
In the control process, by reducing the working frequency of the compressor and closing the first control valve 710 or the second control valve 720, the energy consumption of the air conditioner on-hook can be greatly reduced under the condition of ensuring that the temperature regulation capacity of the air conditioner on-hook meets the requirement; in the process that the temperature difference is from greater than a fourth preset temperature difference to less than or equal to a third preset temperature difference, the first wind wheel works to fully and quickly dissipate energy (cold energy or heat energy) on the first heat exchanger [ or the second wind wheel works to fully and quickly dissipate energy (cold energy or heat energy) on the second heat exchanger ], the adjusting speed of the indoor temperature is guaranteed, and meanwhile, the first wind wheel or the second wind wheel is turned off when the temperature difference is less than or equal to the fourth preset temperature difference, so that the energy consumption of an air conditioner on-hook is reduced while the indoor temperature is guaranteed.
In order to realize the unification of noise reduction and energy output, the control method of the on-hook air conditioner further comprises the following steps:
detecting the number of people in a room, and setting the number as a first number;
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. The number of people detected for the first time is counted 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;
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 duration 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 on-hook is unchanged; when the number of people detected after the time period is not zero, the on-hook air conditioner is adjusted according to requirements, for example, the rotating speed of the wind wheel is reduced, so that indoor noise is reduced.
Comparing the first number of people with the second number of people;
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.
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. Namely, the unification of noise reduction and temperature adjustment is realized.
In order to uniformly save energy and maintain indoor temperature, the control method of the air conditioner on-hook machine further comprises the following steps:
detecting the number of people in a room, and setting the number as a first number;
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. The number of people detected for the first time is counted 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;
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 duration 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 on-hook is unchanged; when the number of people detected after the time period is not zero, the on-hook air conditioner is adjusted according to requirements, for example, the rotating speed of the wind wheel is reduced, so that indoor noise is reduced.
Comparing the first number of people with the second number of people;
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 reduction of the heat energy input in unit time is smaller due to the increase of the wind speed, 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.
