Drawings
The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a schematic diagram of an energy saving control method according to an embodiment of the present invention.
Fig. 2 is a schematic diagram of an energy saving control method according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
When the air conditioner is started in a cooling or heating mode, in order to protect the compressor and prolong the service life of the compressor, the compressor is started or stopped to meet a time condition of preset time (such as 3 minutes) besides a temperature condition, namely the temperature condition is judged to control the starting and stopping of the compressor at least after the compressor is started or stopped for the preset time.
However, when the air conditioner is timed and the shutdown time is reached, the compressor must be stopped immediately. When the existing air conditioner is in a sleep shutdown mode or a timing shutdown mode, the compressor is normally controlled according to a related mode before the set time of the air conditioner reaches shutdown, and special control is not performed for a certain time in advance for the sleep shutdown mode or the timing shutdown mode, so that the compressor may be still in an on state when the shutdown time of the air conditioner reaches, so that the air conditioner has a lot of cold or heat which is not released to cause energy waste, the optimal matching of energy conservation and comfort is not achieved, and meanwhile, the compressor may be forcibly shut down when the preset time is not fully opened, and the service life of the compressor is influenced.
Based on this, in sleep shutdown and timing shutdown modes, the embodiment of the invention reverses a period of time before shutdown, and sets a new control rule for the compressor in the period of time, so that the start/stop of the compressor is not controlled by the conventional temperature control rule, but runs according to an increased energy-saving control mode.
An energy saving control method of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1.
The energy-saving control method of the air conditioner according to the embodiment of the first aspect of the invention comprises the following steps:
and S1, judging whether to enter a sleep shutdown mode or a timing shutdown mode.
And S2, if yes, entering an energy-saving control mode when the set shutdown time is the first time a, and meeting the requirement that the starting time and the shutdown time of the whole compressor are more than or equal to the preset time. That is, as long as the mobile terminal is in the sleep-off mode or in the timed-off mode, the mobile terminal can enter the energy-saving control mode when the distance between the mobile terminal and the set off time is the first time a. The term "full range" refers to that the energy-saving control mode is performed from a time a after shutdown to shutdown in the energy-saving control mode.
The energy saving control mode includes:
and S3, adjusting the on-off state of the compressor when the distance setting shutdown time is in the range of [ the first time a and the second time b ], so that the compressor is in the shutdown state when the distance setting shutdown time is in the second time b.
S4, the distance setting shutdown time is in the range of [ second time b, third time c ], S41, and whether the temperature difference t is larger than the first temperature difference value e1 or not is judged. The temperature difference is defined using the following manner: in the heating mode, the temperature difference T is equal to the set temperature T1 — the indoor temperature T2, and in the cooling mode, the temperature difference T is equal to the indoor temperature T2 — the set temperature T1. S42, if the temperature difference t is larger than e1, the compressor is started. S43, if the temperature difference t is less than or equal to e1, the compressor keeps a shutdown state, temperature judgment is continuously carried out, and the compressor is started until the temperature difference t is more than e 1. If the temperature difference t is always equal to or less than e1, the compressor remains in the shutdown state for this period of time.
S5, if the distance setting shutdown time is in the range of [ third time c, 0], the compressor is kept or switched to a shutdown state until the whole air conditioner is shut down; or the compressor is kept or switched to the running state to run, and finally the compressor is stopped and kept until the whole air conditioner is closed, wherein a is more than b and more than c.
Therefore, the energy-saving control mode is entered when the compressor is in the first time from shutdown, the on-off of the compressor is not performed according to the conventional temperature control mode, but the first time period is divided into 3 time periods, and the working state of the compressor is adjusted in the first time period [ a, b ] so that the compressor is adjusted to be in the shutdown state when the time period is over; then in a second time period [ b, c ], taking the temperature difference between the set temperature and the indoor temperature as a consideration factor, and adjusting the on and off of the compressor to preliminarily release the cold/heat of the air conditioner; and in the last time period [ c, 0], the opening and closing state of the compressor is adjusted again, the compressor is stopped for enough time before the complete machine is stopped, and the cold quantity/heat quantity is fully released again. Therefore, the operation logic is reasonably adjusted, the air conditioner is comfortable and energy-saving to the maximum extent, and the related start-stop protection of various loads can be carried out, so that the service life of the air conditioner is prolonged.
In some embodiments, the distance setting shutdown time is in the range of [ the first time a, the second time b ], and the following step S31 is executed: firstly, judging the opening and closing state of the compressor, and controlling the opening and closing sequence of the compressor according to the current opening and closing state; and then adjusting the starting time and the stopping time of the compressor according to whether the temperature difference t is greater than the second temperature difference e 2.
That is to say, in the first time period, the on-off control of the compressor not only considers the on-off state of the compressor at the first time a from the shutdown, but also considers the temperature difference, and regulates the startup time and the shutdown time by referring to the temperature difference, so that the release time and the release duration of the cold/heat are more reasonable.
Alternatively, at the first time a from the shutdown time, if the compressor is in the running state, step S32 is executed: and judging whether the temperature difference t is larger than e 2.
And S33, if so, stopping the compressor for a fifth time period g after the compressor keeps running for a fourth time period f, and meeting the requirement that f + g is equal to a-b, wherein f is larger than g.
And S34, if not, stopping the compressor for a fifth time length g after the compressor keeps running for a fourth time length f, and meeting the requirement that f + g is equal to a-b, wherein f is less than g.
From this, if the compressor is in the running state when shutting down first time a apart from, then continue letting the compressor operation fourth time length f, later make the compressor shut down until first time slot end, whether through judging the difference in temperature value in predetermineeing the within range, adjust the time that the length was during and shut down when the start was long, control compressor start time is longer when the difference in temperature is great like this, so that indoor temperature is close to the settlement temperature gradually, the body feels more comfortable, control compressor shut down time is longer when the difference in temperature is less, so that cold volume/heat fully release, simultaneously more energy-conservation.
In some embodiments, a is taken from 30 minutes to 40 minutes, b is taken from 20 minutes to 25 minutes, c is taken from 10 minutes to 15 minutes, e1, e2 are taken from 1.5 ℃ to 3 ℃, h is taken from 3 minutes to 5 minutes. That is, the above parameters are each selected from a value within the corresponding range. When the temperature difference t is larger than e2, f is 7, and g is 3; when the temperature difference t is less than or equal to e2, f is 3, and g is 7. Therefore, the cold energy is fully released on the premise of not influencing the general operation of the sleep mode.
For example, in one embodiment, a is 30min, b is 20min, c is 10min, e1 is e2 is 1.5 ℃, and h is 3 min.
Therefore, logic adjustment is carried out to prolong the service life of the compressor, and the start and stop of the compressor in the whole operation period are ensured to meet the 3-minute protection rule.
In some embodiments, at a first time a from the shutdown time, if the compressor is in a shutdown state,
s35, judging whether the temperature difference t is larger than e2,
and S36, if the temperature difference t is larger than e2, stopping for a sixth time period h, starting to operate for a seventh time period k, stopping for an eighth time period m, and meeting the requirement that h + k + m is a-b.
S37, if the temperature difference t is less than or equal to e2, the shutdown is kept until the third time c after the shutdown is carried out when the distance from the set shutdown time is within the range of the first time a and the second time b.
Therefore, when the temperature difference is large, the compressor is stopped for the sixth time, then the compressor is started to reduce the temperature difference to enable the indoor temperature to be more comfortable, and then the compressor is stopped to save energy and enable the load of the compressor to have full rest; when the temperature difference is small, the compressor is directly stopped so as to fully release the heat/cold.
In some embodiments, the distance setting shutdown time is in the range of [ third time c, 0], and the following steps are performed:
and S51, judging the opening and closing state of the compressor.
And S52, when the time is the third time c from the shutdown time, if the current compressor is in the shutdown state, the compressor is started firstly, and after the starting time reaches the preset time p, the compressor is stopped.
And S53, when the time is the third time c from the shutdown time, if the current compressor is in the running state, judging whether the continuous running time meets the preset duration p.
And S54, if yes, stopping the compressor until the whole air conditioner is shut down.
And S55, if the continuous running time does not meet the preset time p, the compressor keeps running state, and the compressor is stopped until the whole air conditioner is closed after the continuous running time meets the preset time p. The continuous operation time here refers to the operation time of the compressor at the last start.
That is, 1) if the temperature difference is not greater than e1 all the time in the second time period, the compressor is stopped all the time in the second time period, after entering the third time period, the compressor is started to operate for the preset time p, and then the compressor is stopped until the air conditioner is stopped.
2) And if the initial temperature difference is not greater than e1 in the second time period and the temperature difference is greater than e1 at any time point in (b, c + p), controlling the compressor to be started and run to the end of the second time period, and controlling the compressor to be in a stop state in the third time period until the shutdown time of the air conditioner is up because the running time of the compressor reaches or exceeds the time p by the beginning of the third time period.
3) And if the initial temperature difference is not greater than e1 in the second time period and the temperature difference is detected to be greater than e1 at any time point in (c + p, c), controlling the compressor to be started and run for a time period p, and then controlling the compressor to be stopped until the air conditioner is stopped.
4) And if the initial temperature difference is larger than e1 in the second time period, starting the compressor to operate in the second time period, and stopping the compressor in the third time period until the air conditioner is shut down.
Therefore, the compressor can be in the running state or the shutdown state at the end of the second time period, the last two states of the compressor are required no matter what state the compressor is in, the compressor is started first and then is shut down, the starting time and the shutdown time exceed p, and therefore the cold quantity or the heat quantity of the air conditioner is released continuously through the temperature of the indoor evaporator by utilizing the principle that the difference between the temperature of the indoor evaporator and the temperature of the indoor environment is at least more than 10 ℃ when the compressor is closed, and the purpose of energy saving is achieved.
In one embodiment, a is 30min, b is 20min, c is 10min, e1 is 1.5 ℃, h is 3, k is 4, and m is 3. When the rules are actually applied, all the time can be flexibly adjusted according to different boxes and different sales areas
In some embodiments, the indoor unit fan is controlled to operate at the lowest gear when the compressor is stopped. Specifically, the rotation speed of the lowest fan may vary according to the type of the air conditioner, and for the air conditioner with a breeze gear and a breeze gear, the lowest gear corresponds to the breeze gear, and at this time, the rotation speed of the fan may be 650 and 750 r/min.
Because the indoor wind speed is high, the temperature exchange is relatively fast, and the compressor is in a closed state, no cold or heat is provided, and the comfort is poor. Therefore, in the embodiment of the invention, in the whole energy-saving control mode, as long as the compressor is in a stop state, the indoor fan is forced to run at the lowest gear, so that the indoor temperature can be prevented from changing too fast, and the indoor comfort can be kept to a certain extent.
An energy saving control method according to an embodiment of the present invention is described below with reference to fig. 2. Wherein the compressor may also be referred to as simply a press.
And adjusting the running time sequence of the compressor in the time interval of [30, 20], namely the second time period, so as to ensure that the compressor is satisfied to stop for at least 3 minutes when the compressor is shut down for 20 minutes.
1) If the compressor is in the running state/the starting state 30 minutes before shutdown, judging whether the temperature difference is not more than 1.5 ℃ in the time interval of [30,27], if the temperature difference is not more than 1.5 ℃, stopping the compressor 27 minutes before shutdown and stopping the compressor 7 minutes after running the compressor for 3 minutes; if the temperature is higher than 1.5 ℃, the compressor is operated for 7 minutes, and is forcibly stopped for 3 minutes 23 minutes before shutdown.
2) If the compressor is in a stop state 30 minutes before shutdown, judging whether the temperature difference is not more than 1.5 ℃ or not within 27 minutes before shutdown, and if the temperature difference is not more than 1.5 ℃, stopping the compressor all the time; otherwise, the compressor is started after 3 minutes, namely 27 minutes before shutdown, and is forcibly stopped after running for 3 minutes.
The compressor has been satisfied to stop for a period of at least 3 minutes 20 minutes prior to shutdown. And (3) judging whether the temperature difference t is not more than 1.5 ℃ in the time interval of [20,10 ].
1) And if the temperature difference t is not more than 1.5 ℃, starting the compressor 10 minutes before shutdown, forcibly stopping the compressor 3 minutes after shutdown, and then keeping the shutdown time of the air conditioner.
2) If the temperature difference t is larger than 1.5 ℃, immediately starting the compressor, and forcibly stopping the compressor if the temperature difference t is larger than 3 minutes before the shutdown; if the starting time of the compressor is less than 3 minutes, the compressor is stopped after being started for 3 minutes, and then the air conditioner is kept to be shut down until the time is up.
