Detailed ways

In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The air conditioner energy-saving control method, control device and air conditioner of the present application will be described below with reference to FIGS. 1-3 .

Referring to FIG. 1 , the present embodiment provides an air conditioner energy-saving control method, the air-conditioner energy-saving control method includes: acquiring the current season; and controlling the input current of the air conditioner according to the current season. At present, the air conditioner has energy-saving control, but there is no special method for how to deal with seasonal energy-saving. This embodiment formulates different energy-saving measures according to the temperature of each season, so as to better realize energy-saving and reduce energy consumption of the air-conditioner.

Specifically, this embodiment considers that the outdoor ambient temperature is different in different seasons, and the demand for cooling capacity or heating capacity of the air conditioner is different under different outdoor ambient temperatures; it is further proposed to distinguish between different seasons, Seasonal energy saving can be realized by regulating the input current of the air conditioner in seasons when the demand for cooling capacity or heating capacity of the air conditioner is not too great.

For example, compared with spring and autumn when the outdoor ambient temperature is relatively suitable in summer when the outdoor ambient temperature is relatively high, the demand for the cooling capacity of the air conditioner is greater in summer than in spring and autumn. The input current of the air conditioner can be adjusted in spring and autumn to achieve spring The energy-saving control of the air conditioner in autumn, and because the cooling capacity of the air conditioner is not too large in spring and autumn, the current regulation will not have a great impact on the temperature control comfort of the air conditioner, and it is also conducive to ensuring user comfort.

Specifically, the input current of the air conditioner may be reduced in seasons when the cooling capacity or heating capacity of the air conditioner is less required. By reducing the input current of the air conditioner, the operating power of each component of the air conditioner, mainly including the compressor, can be reduced, thereby achieving the effects of reducing power consumption and saving energy.

The air conditioner energy-saving control method provided in this embodiment proposes to distinguish between different seasons, and realize seasonal energy saving by adjusting the input current of the air conditioner in seasons when the demand for cooling capacity or heating capacity of the air conditioner is not too large; The embodiment conducts energy-saving control of air conditioners from the perspective of seasons, and formulates different energy-saving measures for different temperatures in different seasons, which not only takes into account the user's temperature comfort, but also performs energy-saving control, which is conducive to reducing the energy consumption of air conditioners. Save electricity.

Further, controlling the input current of the air conditioner specifically includes: controlling the input current at the main power line of the air conditioner. The main power cord of the air conditioner is used to be plugged and connected to an external socket, that is, this embodiment proposes to regulate the total input current of the air conditioner. Since the control circuit of the air conditioner includes a power transmission control circuit, the input current can be regulated directly through the controller of the air conditioner itself by controlling the power transmission control circuit, which is simple and easy to operate.

On the basis of the above embodiments, further, according to the season of the current time, controlling the input current of the air conditioner specifically includes: reducing the input current of the air conditioner when the current time is in spring or autumn. The outdoor ambient temperature in spring and autumn is more suitable than that in summer and winter, which makes the demand for cooling or heating capacity of the air conditioner smaller. In spring or autumn, the input current of the air conditioner can be correspondingly reduced to reduce the operation of the air conditioner. Power, reduce the energy consumption of the air conditioner.

On the basis of the above embodiments, further reducing the input current of the air conditioner specifically includes: acquiring a theoretical current when the air conditioner operates according to set conditions; reducing the input current of the air conditioner so that the input current is smaller than the theoretical current. The setting conditions of the air conditioner specifically include operating conditions set by a user when turning on the air conditioner, such as a set target temperature and a set wind speed of the air conditioner. When the air conditioner is in normal operation, it operates according to the corresponding theoretical current under the set conditions. In this embodiment, the input current of the air conditioner is reduced on the basis of the theoretical current, so that the actual input current of the air conditioner is smaller than the theoretical current.

Further, obtaining the theoretical current when the air conditioner operates according to the set conditions specifically includes: first controlling the air conditioner to operate normally according to the set conditions, and then monitoring Obtain the theoretical current when the air conditioner operates according to the set conditions; then control and reduce the input current of the air conditioner so that the input current is less than the theoretical current. Alternatively, the theoretical current when the air conditioner operates according to the set conditions can be obtained through theoretical calculation, and then the input current of the air conditioner can be reduced based on the theoretical current.

Further, controlling the input current of the air conditioner according to the season of the current time further includes: when the current time is summer or winter, controlling the input current of the air conditioner to operate according to a theoretical current. That is, in summer or winter, the input current of the air conditioner can be operated at the theoretical current without reducing the input current of the air conditioner, so as to ensure the comfort of users in summer or winter. Because the temperature is high in summer, the user has a greater demand for the cooling capacity of the air conditioner, and the temperature is lower in winter. If the user uses the air conditioner for heating, the demand for the heating capacity of the air conditioner is also greater. The current will affect the cooling or heating efficiency of the air conditioner, thereby affecting the comfort of the user. Therefore, in summer or winter, in order to ensure user comfort, the input current of the air conditioner may not be reduced.

On the basis of the above embodiments, further, referring to FIG. 2 , reducing the input current of the air conditioner so that the input current is less than the theoretical current specifically includes: when the current time is in spring, reducing the input current of the air conditioner so that the input current is the theoretical current 55%-65% of the current; when the current time is in autumn, reduce the input current of the air conditioner so that the input current is 70%-80% of the theoretical current.

This embodiment describes the specific reduction degree of the input current. Specifically, this embodiment is mainly aimed at cooling working conditions, that is, when the current time is in spring and the air conditioner is in the cooling working condition, reduce the input current of the air conditioner so that the input current is 55%-65% of the theoretical current; In autumn and when the air conditioner is in cooling mode, reduce the input current of the air conditioner so that the input current is 70%-80% of the theoretical current.

In this embodiment, considering that the outdoor air temperature in spring is relatively lower than that in autumn, the demand for the cooling capacity of the air conditioner in spring is correspondingly lower than that in autumn. Therefore, the input current of the air conditioner in spring can be reduced. It is greater than the reduction degree of the input current of the air conditioner in autumn.

And in spring, the input current is 55%-65% of the theoretical current. The reduction of the input current is suitable for the temperature environment in spring. It can not only reduce the input current to achieve the effect of energy saving in spring, but the reduction of the input current is not too much. Large, it is also conducive to ensuring the comfort of the air conditioner and ensuring the user experience. In autumn, the input current is 70%-80% of the theoretical current. The reduction of the input current is suitable for the temperature environment in autumn. It can save energy in spring by reducing the input current, and the reduction of the input current is not too large. , It is also beneficial to ensure the comfort of the air conditioner and the user experience.

On the basis of the above embodiments, further, acquiring the season at the current time specifically includes: preset date parameters of each season; and acquiring the season at the current time according to the date parameters at the current time. The start date of each season can be preset first, and then the season of the current time can be judged according to the date of the current time.

Specifically, in this embodiment, the date parameters of each season can be preset according to common knowledge of dates. That is, according to common sense, March, April and May can be regarded as spring, June, July and August as summer, September, October and November as autumn, and December and January as autumn. and February as winter.

Alternatively, the date parameters of each season may be preset according to specific local air temperature parameters, so that the average outdoor temperature in winter<the average outdoor temperature in spring<the average outdoor temperature in autumn<the average outdoor temperature in summer. That is to say, the period of time when the average outdoor temperature is the lowest and the cooling mode will not be turned on (for example, the average outdoor temperature is less than or equal to 15°C) is divided into winter, and the operation of the air conditioner is controlled according to the control logic in winter; the average outdoor temperature is the highest and the cooling demand is large (For example, the average outdoor temperature is greater than or equal to 35°C) is divided into summer, and the air conditioner is controlled according to the control logic in summer; the time between winter and summer is divided into spring and autumn.

Further, the season in which the current time is located specifically includes at least one of spring, summer, autumn and winter. That is, the division of seasons is not limited to four seasons. In some special areas, it may only be divided into spring and autumn; or only divided into spring, autumn and summer, etc.; it can be divided according to the specific local environmental parameters.

On the basis of the above-mentioned embodiments, further, obtaining the season at the current time further includes: preset temperature parameters of each season; obtaining the actual outdoor temperature at the current time; season. That is, the season at the current time can also be judged according to the actual outdoor temperature at the current time. The temperature range corresponding to each season can be preset first, and the season in which the current time is determined according to the temperature range of the actual outdoor temperature at the current time, and then the corresponding control logic is performed.

Specifically, the outdoor temperature can be set to be less than or equal to 15°C in winter; 15-25°C in spring; 25-35°C in autumn; and greater than or equal to 35°C in summer. The season at the current time is determined according to the actual outdoor temperature at the current time. The seasons divided according to the temperature parameters are divided according to the scheme of reducing the input current of the air conditioner to save energy. That is, when the actual outdoor temperature is less than or equal to 15°C, it is judged as winter, or when the actual outdoor temperature is greater than or equal to 35°C, it is judged as summer, and there is no need to reduce the input current. current to ensure the air-conditioning effect and avoid user discomfort; when it is judged to be spring or autumn, the corresponding control operation of reducing the input current can be performed to realize seasonal energy saving.

The specific division of the temperature of each season is different from the division of the temperature of the four seasons in common sense. This division is based on the idea of reducing the input current to save energy, and starting from the comfort of the user, based on the user's personal experience. In the temperature range of great discomfort, further energy saving based on the existing inverter air conditioner can be achieved by reasonably reducing the input current, and the theoretical current operation of the air conditioner can be maintained in the temperature range that may cause greater discomfort, so as to ensure that the user From the perspective of seasonal energy saving, this scheme further taps the energy-saving potential of air conditioners, which is conducive to saving electric energy and reducing energy consumption of air conditioners.

Further, determining the season of the current time according to the date parameter and determining the season of the current time according to the temperature parameter can also be used in combination. It can first determine the season of the current time according to the date parameter, and then determine whether the actual outdoor temperature at the current time is within the preset temperature range of the season corresponding to the date parameter; if so, control the temperature of the air conditioner according to the season of the current time If the input current is not present, determine the season corresponding to the actual outdoor temperature, and control the input current of the air conditioner according to the corresponding season.

In this embodiment, the season of the current time is judged according to the temperature parameter, which is beneficial to obtain accurate and reasonable input current control logic.

On the basis of the above embodiments, further, an air conditioner energy-saving control method further includes: receiving an input current adjustment instruction sent by a user; and controlling the input current of the air conditioner according to the input current adjustment instruction. That is, during the execution of the input current control logic provided by the above-mentioned embodiments, if the user is not satisfied with the current control effect of the air conditioner, he can manually adjust the input current and send adjustment instructions to the air conditioner, and the air conditioner will adjust The adjustment command adjusts the input current to ensure user experience.

For example, when it is determined that the current time is spring or autumn and the input current of the air conditioner is reduced, if the user feels that the cooling or heating capacity of the air conditioner is insufficient in the current situation, the user can send an input current increase command to the air conditioner to increase Large input current improves cooling or heating efficiency to meet user needs. Or, when it is determined that the current time is summer or winter, and the input current of the air conditioner is controlled to run according to the theoretical current, if the user feels that the cooling capacity or heating capacity of the air conditioner is too large in the current situation, the input current reduction can be sent to the air conditioner. Instructions to reduce input current, reduce cooling or heating efficiency, and meet user needs.

Further, the input current adjustment instruction sent by the user specifically includes: an input current increase instruction, an input current decrease instruction, or an input current gear instruction sent according to a preset input current gear, and the like. The sending method of the input current adjustment instruction includes: the user may send the input current adjustment instruction through a remote control or a control button on the air conditioner or voice input.
