The user can select automatic power-saving control or normal operation control according to the requirement.

And when the setting operation of the user is acquired, determining to perform automatic power-saving control or normal operation control according to the setting operation. And when determining to perform automatic power-saving control according to the setting operation, starting the power-saving control of the air conditioner, wherein the automatic power-saving control comprises full-time power-saving control, and the full-time power-saving control is AI intelligent full-time power-saving control: 24 hours a day, non-scene power saving control, realizes the automatic power saving control of the air conditioner in the whole time.

In the full-time power-saving control process, the target environmental parameters are adjusted, so that the energy consumption corresponding to the air conditioner reaching the target environmental parameters is less than the energy consumption corresponding to the air conditioner reaching the current environmental parameters, and the energy-saving control is realized on the premise of not influencing the comfort of a user. Specifically, after the air conditioner starts the power-saving control, current environmental parameters and a comfortable PMV interval are obtained; judging whether the PMV value corresponding to the current environmental parameter is in the comfortable PMV interval, if so, determining a target PMV value in the comfortable PMV interval according to the PMV value, determining a target environmental parameter according to the target PMV value, and controlling the air conditioner to run by the target environmental parameter, wherein the energy consumption corresponding to the target environmental parameter when the air conditioner runs is less than the energy consumption reaching the current environmental parameter pair.

Specifically, there are various ways of determining the target PMV value in the comfortable PMV interval according to the PMV value, and the relationship between the PMV value and the target PMV value may be set according to the user requirement, for example, if the user sets the difference between the target PMV value and the PMV value as a preset difference, and when the current PMV value is 0.1, the preset difference is adjusted upward from 0.1 in the cooling mode, and the preset difference is adjusted downward in the heating mode. Or setting the target PMV value as the boundary value of the comfortable PMV interval, and performing power saving control by adopting the boundary value of the comfortable PMV interval, so that the power saving effect is good.

The mode of determining the corresponding target environment parameter according to the target PMV value may at least include one of the following two: if the corresponding relation between the preset PMV value and the environmental parameter is formed, a relation list is formed, and the environmental parameter corresponding to the target PMV is found out from the preset relation list and is used as the target environmental parameter; for another example, a PMV value calculation formula is preset, the PMV value calculation formula is related to the environmental parameter, and after the target PMV value is determined, the target environmental parameter is calculated by formula back-stepping. Further, in order to make the calculation result of the target environment parameter closer to the current environment condition of the air conditioner and make the power saving adjustment effect better, the PMV value calculation formula is also related to the current environment parameter, that is, the target environment parameter is determined by the PMV value and the current environment parameter.

The environmental parameters described in this embodiment include one or more of temperature, humidity, wind speed, and the like.

Because the price of electricity of valley power consumption period is lower, when increasing the refrigerating capacity of air conditioner promptly, can save the charges of electricity when the air conditioner moves, and the operating parameter of air conditioner is in comfortable operating parameter interval, can guarantee user's comfort level.

And when the current electricity utilization period is the peak electricity utilization period, adjusting the operation parameters of the air conditioner to the operation parameters with the lowest energy consumption in the comfortable operation parameter interval so as to reduce the refrigerating capacity of the air conditioner.

and step S120, controlling the air conditioner to operate according to the user historical habit environmental parameters.

In this embodiment, the sleep mode adopts adaptive ECO power saving control, when the user is in a sleep state, the body temperature is lowered, and the temperature requirement on the environment is not so high, and at this time, in order to save electric energy, the sleep energy saving mode is started after the user is detected to sleep, and if the target environment parameter is adjusted up, the energy consumption for the air conditioner to operate to reach the target environment parameter is less than the energy consumption for reaching the current environment parameter.

The adjustment range of the target environment parameters can be specifically set by a user, if the set temperature is increased by 1-2 ℃, the current environment temperature is obtained after the air conditioner enters a sleep mode, and the current environment temperature is increased by 1-2 ℃ on the basis of the current environment temperature so as to operate at the constant temperature after adjustment, and the energy consumption of the air conditioner is reduced.

step S150, determining an energy-saving temperature according to the environment temperature change curve and the comfortable PMV interval;

and step S160, controlling the air conditioner to run at constant temperature after the ambient temperature reaches the energy-saving temperature.

This embodiment is applicable to current operating environment and satisfies the condition of start mode, adopts the energy-conserving intelligent start function energy-conserving start of start mode the air conditioner, wherein, comfortable PMV interval includes that the user is comfortable between the temperature range, and this embodiment is based on energy-conserving start-up, only need acquire the comfortable temperature range of user can. The energy-saving starting is that a critical temperature value with the highest marginal value is analyzed based on PMV comfort and the cooling rate of the air conditioner, the energy-saving temperature is output, and meanwhile, the air conditioner is started in advance when a user goes home based on an electronic fence technology, so that the energy-saving starting is realized.

The set temperature is the temperature required by a user, and when the air conditioner receives the set temperature, the air conditioner normally operates according to the set temperature, so that the indoor environment temperature reaches the set temperature. The set temperature can be a set temperature input by a user through a remote controller or a mobile terminal, for example, when the user triggers a setting operation through the remote controller or the mobile terminal, the terminal receives the setting operation and then acquires the corresponding set temperature from the setting operation. Or, the set temperature is a preset fixed starting temperature, and if the terminal detects that the air conditioner is started, the preset set temperature is directly obtained. Or, the set temperature may be a user historical set temperature, and if the air conditioner is detected to be started, the corresponding set temperature in the user historical behavior data is acquired.

In order to enable the ambient temperature of an acting space of the air conditioner to quickly reach a set temperature and further run at the set temperature at a constant temperature, in the normal use process, after the air conditioner is started, a compressor runs at the maximum running frequency, and a fan rotates at the maximum rotating speed, so that the change rate of an ambient temperature change curve is larger in the process of starting the air conditioner, and due to the marginal value principle, when the ambient temperature is close to the set temperature, the change rate of the ambient temperature is smaller and smaller, the temperature reaching time of the environment is longer, and therefore in the actual application process, when the air conditioner runs at the set temperature, the indoor ambient temperature can reach the set temperature possibly after the air conditioner runs at a high frequency for a long time; it is also possible that the indoor ambient temperature never reaches the set temperature. If the indoor environment temperature reaches the set temperature, the air conditioner can run for a long time at high frequency under the two conditions, and electric energy is wasted. This embodiment is through obtaining after setting for the temperature, according to set for the temperature and acquire the ambient temperature variation curve of air conditioner in the actual operation process, with energy-conserving temperature is confirmed to ambient temperature variation curve and the comfortable temperature interval of user, reaches in the environment of being in behind the energy-conserving temperature, the air conditioner constant temperature operation when guaranteeing that ambient temperature reaches the comfortable temperature of user's demand, avoids the long-time high frequency operation of air conditioner, the energy saving.

The environment temperature change curve can be a preset environment temperature change curve, each set temperature experiment is adopted to detect the environment temperature change curve of an action space where the air conditioner is actually located, a mapping relation between each set temperature and each environment temperature change curve is formed, after the set temperature is obtained, the environment temperature change curve of the air conditioner is obtained according to the mapping relation between the set temperature and the environment temperature change curve, then the energy-saving temperature is determined according to the environment temperature change curve and a user comfortable temperature interval, and the user comfortable temperature interval is a temperature interval corresponding to the comfortable PMV interval. The environmental temperature change curve can also be recorded in historical use data, for example, in the historical operation process of the air conditioner, the set temperature and the actual environmental temperature change curve are recorded to form the mapping relation between each set temperature and the corresponding environmental temperature change curve, after the set temperature is obtained, the corresponding environmental temperature change curve is obtained from the historical set temperature, and then the energy-saving temperature is determined according to the environmental temperature change curve and the comfortable temperature interval of the user. It is understood that the relationship between the ambient temperature variation curve and the set temperature includes, but is not limited to, the above relationship, which is only an example of two embodiments.

The user comfortable temperature interval can be a preset user comfortable temperature interval, such as an ambient temperature which is comfortable according to actual experience of most people. The comfortable temperature interval of the user can also be determined according to the PMV (comfortable sensation value) of the user, the comfortable temperature interval of the user is determined, the comfortable temperature interval of the user is stored in a memory, the comfortable PMV interval is obtained in the energy-saving starting process, and the comfortable temperature interval of the user is determined according to the comfortable PMV interval. The comfortable PMV interval and the moderate temperature interval of the user can be associated through a mapping relation, or the comfortable temperature interval is calculated through a PMV calculation formula.

The comfort interval can be obtained through a preset and fixed comfortable PMV interval, and if the comfort PMV interval is-0.5, the comfort PMV interval is directly obtained by-0.5. The comfortable PMV interval also can be determined according to the historical comfortable PMV interval of the user, wherein the comfortable PMV interval is recorded in history when the user uses the air conditioner. In order to improve the experience of each user, the comfortable PMV intervals corresponding to different users are different, so that the energy-saving temperature is determined by acquiring user information, further acquiring the comfortable PMV interval corresponding to the user information according to the user information, further determining the energy-saving temperature according to the comfortable PMV interval corresponding to the user information and an environment temperature change curve, and aiming at the different energy-saving temperatures corresponding to the different users, the energy-saving starting effect is improved.

The energy-saving temperature is in an overlapping area of the environment temperature change curve and the user comfort temperature interval, namely the energy-saving temperature is any temperature of the environment temperature change curve in the user comfort temperature interval or the temperature meeting specific conditions.

In this embodiment, the energy-saving temperature may be an energy-saving temperature that meets the most comfortable requirement of the user when the air conditioner is operating, or may be an energy-saving temperature that meets the most comfortable requirement of the user when the air conditioner is operating. Therefore, the energy-saving temperature acquisition mode comprises at least one of the following modes:

1. and taking the boundary temperature of the environment temperature change curve in the user comfortable temperature interval as the energy-saving temperature.

Under the mode of refrigeration, ambient temperature change curve gets into the comfortable temperature interval of user gradually by high temperature low temperature, works as ambient temperature change curve gets into during the comfortable temperature interval of user, confirm current ambient temperature for the general comfortable ambient temperature of user, in order to practice thrift the electric energy, can select this moment the highest boundary temperature in the comfortable temperature interval is regarded as energy-conserving temperature, with energy-conserving temperature constant temperature operation adjusts the air conditioner in advance and falls the frequency operation, realizes satisfying the general comfortable of user, but the most energy-conserving operation.

Under the heating mode, ambient temperature change curve becomes high temperature by low temperature, gets into the comfortable temperature interval of user gradually, works as ambient temperature change curve gets into during the comfortable temperature interval of user, confirm current ambient temperature for the general comfortable ambient temperature of user, in order to practice thrift the electric energy, can select this moment the highest boundary temperature in the comfortable temperature interval is regarded as energy-conserving temperature, with energy-conserving temperature constant temperature operation adjusts the air conditioner in advance and moves that falls the frequency, realizes satisfying the general comfortable of user, but the most energy-conserving operation.

2. And when the air conditioner is used for refrigerating, taking the temperature with the maximum slope of the ambient temperature change curve in a user comfortable temperature interval as the energy-saving temperature.

Under the refrigeration mode, ambient temperature change curve opens to the constant running in-process from the air conditioner, and ambient temperature change curve gradually tends to the horizon, because ambient temperature change curve is not necessarily regular curve, and the tangent slope of any point on the curve is not the regular change, the more the tangent slope that any temperature on the ambient temperature change curve corresponds is, then ambient temperature change speed is slow, the less the tangent slope that any temperature on the ambient temperature change curve corresponds is, then ambient temperature change is fast. When the change rate of the environmental temperature is slower, the current environmental temperature is closer to the boundary value, and the temperature with the maximum slope of the change curve of the environmental temperature in the comfortable temperature interval of the user is selected as the energy-saving temperature, so that a certain energy-saving effect is achieved, and the environmental comfort is ensured.

3. And when the air conditioner heats, taking the temperature with the minimum slope of the ambient temperature change curve in the comfortable temperature interval of the user as the energy-saving temperature.

Under the heating mode, ambient temperature change curve opens to the constant running in-process from the air conditioner, and ambient temperature change curve gradually tends to the water line, because ambient temperature change curve is not necessarily regular curve, and the tangent slope of any point on the curve is not the regular change, the more the tangent slope that any temperature on the ambient temperature change curve corresponds is, the faster the ambient temperature change speed is, the less the tangent slope that any temperature on the ambient temperature change curve corresponds is, the slower the ambient temperature change is. When the change rate of the environmental temperature is slower, the current environmental temperature is closer to the boundary value, and the temperature with the minimum slope of the change curve of the environmental temperature in the comfortable temperature interval of the user is selected as the energy-saving temperature, so that a certain energy-saving effect is achieved, and the environmental comfort is ensured.

In a further scheme, the energy-saving temperature can be determined by combining the operation time of the air conditioner, for example, the temperature of the environment temperature change curve, which has the temperature reaching time less than the preset time and the maximum slope in the user comfortable temperature interval, is taken as the energy-saving temperature. The temperature with the maximum slope and the temperature reaching time length smaller than the preset time length is selected as the energy-saving temperature, so that the high-frequency operation time of the air conditioner can be reduced, and a certain energy-saving effect is achieved.

4. And taking the temperature of the ambient temperature change curve, which is closest to the current user sensitivity value in the user comfort temperature interval, as the energy-saving temperature.

And acquiring a current user front body sensation value, determining a comfortable temperature value according to the current sensation value, and acquiring the temperature of the environment temperature change curve, which is closest to the comfortable temperature value in a user comfortable temperature interval, as the energy-saving temperature, so that the most comfortable and general energy-saving operation of the user is realized.

It is understood that, in other embodiments, the manner of obtaining the energy saving temperature may also be: and taking the intermediate temperature or the average temperature of the environment temperature change curve in the comfortable temperature interval of the user as an energy-saving temperature, and ensuring that the operation is comfortable and energy-saving at the energy-saving temperature.

The energy-saving starting method of the embodiment can be executed before the air conditioner is started in advance, so that the air conditioner can directly run at the energy-saving temperature when being started. The method can also be executed when the air conditioner is started, the set temperature is obtained when an air conditioner starting instruction is received, the energy-saving temperature is further determined, and the air conditioner runs at the constant energy-saving temperature after the ambient temperature reaches the energy-saving temperature. The method can also be executed after the air conditioner is started, if the air conditioner is started, the user updates the current set temperature, the terminal acquires the updated set temperature, then determines the environment temperature change curve of the updated set temperature according to the updated set temperature, determines the energy-saving temperature according to the environment temperature change curve of the updated set temperature and the comfortable temperature interval of the user, and then updates the energy-saving temperature when the air conditioner is started according to the energy-saving temperature corresponding to the updated set temperature.

To achieve energy-saving operation at each stage.

It can be understood that, in other embodiments, the current operating environment of the air conditioner simultaneously satisfies the conditions of two or more preset scenes, and the energy saving is performed by using the energy saving scene modes corresponding to the two preset scenes. If the scene of pre-starting and energy-saving starting is detected, when the user performs pre-starting control based on the mobile terminal (the air conditioner is controlled to be started in advance), the air conditioner is started in an energy-saving mode after the position of the user meets the pre-starting condition, and the energy-saving control is performed on a plurality of scenes simultaneously.
