In order to maintain a comfortable ambient temperature, an air conditioner has become an indispensable equipment in human life. In recent years, although air conditioner technology has been developed to a very mature level, there are still some areas where improvements are needed in the existing air conditioners. For example, the operation mode and the target operation temperature of the existing air conditioner are directly input by a user, and the user often sets the operation mode and the target operation temperature of the air conditioner by means of subjective body feeling without referring to other objective data; therefore, the target operation temperature and even the operation mode input by the user at will often cannot form the optimal heat exchange mode, that is, the setting mode easily causes unnecessary energy loss, and the air conditioner cannot enable the user to experience comfortable sensible temperature when exchanging heat according to the heat exchange mode. Especially for commercial air conditioners, the arrangement mode is easy to cause great energy waste, and meanwhile, a user cannot experience comfortable body sensing temperature, and further the user experience is sharply reduced.
Accordingly, there is a need in the art for a new control method for an air conditioner to solve the above-mentioned problems.

As can be understood by those skilled in the art, in the technical solution of the present invention, the control method of the present invention includes the following steps: acquiring indoor temperature; setting an operation mode of the air conditioner according to the indoor temperature; selectively setting a target operating temperature of the air conditioner according to an operating mode of the air conditioner. It can be understood that when the indoor temperatures are different, the operation modes that the air conditioner needs to execute are obviously different, and the invention can automatically set the operation modes of the air conditioner according to the indoor temperatures so as to ensure that the operation modes of the air conditioner can be matched with the indoor temperatures; meanwhile, the target operation temperature of the air conditioner can be selectively set according to the operation mode of the air conditioner, when the indoor temperature is in the proper temperature range, the air conditioner does not need to exchange heat with indoor air, only the function of circulating the indoor air needs to be realized, and under the condition, the comfortable experience of a user can be ensured without setting the target operation temperature of the air conditioner; and when the indoor temperature is not in the proper temperature range, the air conditioner needs to exchange heat with the indoor air, and under the condition, the control method can also set the target operation temperature of the air conditioner, so that the air conditioner can automatically set the most proper operation mode and the target operation temperature according to the actual use requirement, a user can experience comfortable sensible temperature, and the energy consumption of the air conditioner can be reduced to the maximum extent.
Further, in a preferred embodiment of the present invention, if the operation mode of the air conditioner is set to a heating mode or a cooling mode, it indicates that the air conditioner needs to exchange heat with indoor air, that is, a target operation temperature of the air conditioner needs to be set; in this case, the present invention can set a target operating temperature of the air conditioner according to an operating mode of the air conditioner in conjunction with the outdoor temperature. It can be understood that the difference between the outdoor temperature and the indoor temperature often directly affects the sensible temperature of the user, and therefore, the target operation temperature is set according to the outdoor temperature and the operation mode, so that the energy consumption of the air conditioner can be effectively reduced while the user can be effectively ensured to experience comfortable sensible temperature, and the heat exchange efficiency of the air conditioner is effectively improved.
Further, in a preferred embodiment of the present invention, when the operation mode of the air conditioner is a cooling mode, it indicates that the indoor temperature is high, and the user has a cooling requirement, i.e. the user needs to obtain a cool feeling. In this case, if the outdoor temperature is less than or equal to the first preset temperature, it indicates that the outdoor temperature is relatively low, and thus, it is necessary to set the target operating temperature to a first lower temperature in order to obtain a cool feeling for the user; if the outdoor temperature is greater than the first preset temperature and less than the second preset temperature, the outdoor temperature is in a relatively high range, and in the temperature range, a user is sensitive to temperature change, so that the third temperature is set to be equal to a first coefficient multiplied by the outdoor temperature plus a first constant, so that the target operation temperature can be changed along with the change of the outdoor temperature, and the user can be guaranteed to obtain a cool feeling all the time; if the outdoor temperature is greater than or equal to the second preset temperature, the outdoor temperature is very high, and therefore, a user can obtain a cool feeling only by setting the target operation temperature to be the second higher temperature, the setting mode not only can effectively reduce the energy consumption of the air conditioner, but also can prevent the problem that the body of the user is uncomfortable due to the fact that the temperature difference between the inside and the outside is too large, and further improves the user experience to the greatest extent.
Further, in a preferred embodiment of the present invention, when the operation mode of the air conditioner is a heating mode, it indicates that the indoor temperature is low, and the user has a heating requirement, that is, the user needs to obtain a warm feeling. In this case, if the outdoor temperature is less than or equal to the third preset temperature, it indicates that the outdoor temperature is low, and therefore, the user can obtain a warm feeling only by setting the target operating temperature to the fourth temperature, which not only can effectively reduce the energy consumption of the air conditioner, but also can prevent the user from easily causing physical discomfort due to excessive temperature difference between the inside and the outside, thereby improving the user experience to the maximum extent; meanwhile, if the outdoor temperature is greater than the third preset temperature and less than the fourth preset temperature, it indicates that the outdoor temperature is in a relatively low range, and in this temperature range, the user is sensitive to the change of the temperature, so the sixth temperature is set to be equal to a second coefficient multiplied by the outdoor temperature plus a second constant, so that the target operating temperature can be changed along with the change of the outdoor temperature, and the user can be guaranteed to obtain a warm feeling all the time; if the outdoor temperature is greater than or equal to the fourth preset temperature, it indicates that the outdoor temperature is still relatively high, and therefore, the target operating temperature needs to be set to a fifth temperature that is higher in order to enable the user to obtain a warm feeling, so as to ensure a good user experience.
Further, in a preferred embodiment of the present invention, if the indoor temperature is less than the preset low temperature threshold, it indicates that the indoor temperature is low, that is, the user feels cold, and at this time, the operation mode of the air conditioner is set to a heating mode, that is, the air conditioner inputs hot air into the room, so that the user can obtain a warm feeling; meanwhile, if the indoor temperature is greater than or equal to the preset low-temperature threshold and less than or equal to the preset high-temperature threshold, it is indicated that the indoor temperature is within a proper temperature range, and a user already has comfortable sensible temperature, and at this time, only the operation mode of the air conditioner needs to be set to be an air supply mode, so that the air conditioner can realize the function of circulating indoor air, and therefore, in this case, the target operation temperature of the air conditioner does not need to be set, and the air conditioner only needs to exchange air; in addition, if the indoor temperature is greater than the preset high temperature threshold, which means that the indoor temperature is high, that is, the user feels heat, at this time, the operation mode of the air conditioner is set to a cooling mode, that is, the air conditioner inputs cool air into the room, so that the user can feel cool.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the steps of the method of the present invention are described herein in a particular order, these orders are not limiting, and one skilled in the art may perform the steps in a different order without departing from the underlying principles of the invention. Furthermore, the terms "first," "second," "third," "fourth," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
First, it should be noted that the preferred embodiment will be described with reference to the case where the air conditioner is a commercial air conditioner used in a market as an example, but it is obvious that the control method of the present invention can also be used for other air conditioners; for example, a household air conditioner or a commercial air conditioner used in an office building. Such variations are not to be regarded as a departure from the basic principles of the invention and are intended to be within the scope of the invention. In the present preferred embodiment, the air conditioner includes an indoor temperature sensor capable of detecting an indoor temperature and an outdoor temperature sensor capable of detecting an outdoor temperature; of course, the invention does not limit the specific installation position and the specific type of the indoor temperature sensor and the outdoor temperature sensor, and technicians can select the temperature sensors according to actual use requirements. Meanwhile, the air conditioner further includes a controller capable of acquiring measurement data of the indoor temperature sensor and the outdoor temperature sensor, and the controller is also capable of controlling the operation of the air conditioner. In addition, it can be understood by those skilled in the art that the present invention does not limit the specific structure and model of the controller, and the controller may be an existing controller of the air conditioner or a controller separately provided to perform the control method of the present invention.
Referring next to fig. 1, a flow chart of the main steps of the control method of the present invention is shown. As shown in fig. 1, based on the air conditioner described in the above embodiment, the control method of the present invention mainly includes the following steps:
s1: acquiring indoor temperature;
s2: setting an operation mode of the air conditioner according to the indoor temperature;
s3: the target operating temperature of the air conditioner is selectively set according to an operating mode of the air conditioner.
Further, in step S1, the controller may acquire the indoor temperature through the indoor temperature sensor; it should be noted that, the present invention does not limit the manner in which the controller acquires the indoor temperature, and the controller may acquire the indoor temperature by using a temperature sensor provided in the air conditioner itself, or may acquire the indoor temperature by using detection data transmitted by another system, that is, the controller may acquire the data of the indoor temperature. Next, in step S2, the controller may set an operation mode of the air conditioner according to the indoor temperature. It should be noted that, the present invention does not limit any specific corresponding relationship between the indoor temperature and the operation mode, and a technician can set the specific corresponding relationship between the indoor temperature and the operation mode according to actual use requirements and specific conditions of the air conditioner. Specifically, such a correspondence relationship is generally related to the operation mode of the air conditioner and the temperature variation range of the place where the air conditioner is used, for example, some air conditioners have only a cooling mode, a heating mode, and an air blowing mode, and other air conditioners have modes other than the cooling mode, the heating mode, and the air blowing mode, and the temperature variation ranges of the places where different air conditioners are used are also different; therefore, in general, a technician needs to divide different temperature zones according to the temperature variation range of the air conditioner use site, and then correspond the operation mode of the air conditioner to the different temperature zones; of course, this setting manner is not limited, and a technician may set the corresponding relationship between the indoor temperature and the operation mode according to actual use requirements.
Further, in step S3, the controller may be capable of selectively setting a target operating temperature of the air conditioner according to an operating mode of the air conditioner. Taking the air conditioner with only three modes of a cooling mode, a heating mode and an air supply mode as an example, if the operation mode of the air conditioner is set to the cooling mode or the heating mode, the target operation temperature needs to be set; and the target operation temperature is not required to be set if the operation mode of the air conditioner is set to the blowing mode. Of course, the air conditioner may have other modes, such as a defrosting mode, a cleaning mode, an anti-freezing mode, etc., and a technician may set whether the target operating temperature needs to be set when the air conditioner operates in each operating mode according to the actual situation of the air conditioner. The solution adjusted according to the specific situation of the air conditioner does not depart from the basic principle of the present invention, and belongs to the protection scope of the present invention. In addition, it should be noted that, the present invention does not set any limit to the specific way of setting the target operating temperature of the air conditioner, and a technician can set the specific way of setting the target operating temperature by himself or herself according to the actual use requirement; for example, the target operating temperature may be set according to an operating mode of the air conditioner and the indoor temperature; specifically, the operation mode of the air conditioner and the indoor temperature may be in a one-to-one correspondence relationship with the target operation temperature, that is, a unique target operation temperature may be determined according to the operation mode of the air conditioner and the indoor temperature; alternatively, the controller may calculate the target operating temperature by using one or more operation formulas and combining the operating mode of the air conditioner and the indoor temperature; of course, the target operating temperature may also be set according to other parameters, such as outdoor temperature, etc. The description of these setting modes is obviously not restrictive, and the skilled person can set the specific setting mode of the target operating temperature according to the actual situation.
Referring now to fig. 2, a flowchart illustrating the steps of a preferred embodiment of the control method of the present invention is shown. As shown in fig. 2, based on the air conditioner described in the above embodiment, the preferred embodiment of the present invention specifically includes the following steps:
s101: acquiring indoor temperature;
s102: judging whether the indoor temperature is smaller than a preset low-temperature threshold or larger than a preset high-temperature threshold; if not, executing step S103; if yes, executing step S104;
s103: setting the operation mode of the air conditioner to be an air supply mode, and not setting the target operation temperature of the air conditioner;
s104: acquiring outdoor temperature;
s105: if the indoor temperature is less than the preset low-temperature threshold value, setting the operation mode of the air conditioner as a heating mode;
s106: if the indoor temperature is larger than the preset high-temperature threshold value, setting the operation mode of the air conditioner as a refrigeration mode;
s107: if the outdoor temperature is less than or equal to the third preset temperature, setting the target operation temperature of the air conditioner as a fourth temperature;
s108: if the third preset temperature is less than the outdoor temperature and less than the fourth preset temperature, setting the target operation temperature of the air conditioner as a sixth temperature;
s109: if the outdoor temperature is greater than or equal to the fourth preset temperature, setting the target operation temperature of the air conditioner as a fifth temperature;
s110: if the outdoor temperature is less than or equal to a first preset temperature, setting the target operation temperature of the air conditioner as the first temperature;
s111: if the first preset temperature is larger than the outdoor temperature and smaller than the second preset temperature, setting the target operation temperature of the air conditioner as a third temperature;
s112: and if the outdoor temperature is more than or equal to the second preset temperature, setting the target operation temperature of the air conditioner as the second temperature.
Further, in step S101, the controller can acquire the indoor temperature through the indoor temperature sensor; it should be noted that, the present invention does not limit the manner in which the controller acquires the indoor temperature, and the controller may acquire the indoor temperature by using a temperature sensor provided in the air conditioner itself, or may acquire the indoor temperature by using detection data transmitted by another system, that is, the controller may acquire the data of the indoor temperature.
Further, in step S102, the controller may determine whether the indoor temperature is less than the preset low temperature threshold or greater than the preset high temperature threshold, so as to set an operation mode of the air conditioner. In the preferred embodiment, if the controller determines that the indoor temperature is greater than or equal to the preset low temperature threshold and less than or equal to the preset high temperature threshold, it indicates that the indoor temperature is within the suitable temperature range, and at this time, step S103 is executed, that is, the operation mode of the air conditioner is set to the air supply mode, and the target operation temperature of the air conditioner does not need to be set. Meanwhile, if the controller judges that the indoor temperature is smaller than the preset low-temperature threshold or the indoor temperature is larger than the preset high-temperature threshold, it indicates that the indoor temperature is not within the proper temperature range, and at this time, the outdoor temperature needs to be continuously acquired to set the target operating temperature of the air conditioner. As can be understood by those skilled in the art, the specific values of the preset low-temperature threshold and the preset high-temperature threshold can be set by the skilled person according to actual use requirements; preferably, the preset low temperature threshold is 20 ℃ and the preset high temperature threshold is 26 ℃. In addition, it should be noted that, although the air conditioner described in the preferred embodiment has only a cooling mode, a heating mode, and an air blowing mode; however, the air conditioner may have other modes, and a technician may adjust the corresponding relationship between the indoor temperature and the operation mode according to the actual situation of the air conditioner.
Further, when the indoor temperature is less than the preset low temperature threshold or the indoor temperature is greater than the preset high temperature threshold, step S104 is executed, that is, the controller can obtain the outdoor temperature through the outdoor temperature sensor; it should be noted that, the present invention does not limit the manner in which the controller obtains the outdoor temperature, and the controller may obtain the outdoor temperature through a temperature sensor provided in the air conditioner itself, or may obtain the outdoor temperature through cloud data, that is, as long as the controller can obtain the data of the outdoor temperature. It can be understood by those skilled in the art that although the target operating temperature is set by the operating mode and the outdoor temperature in the preferred embodiment; however, it is obvious to the skilled person that the setting mode of the target operating temperature can be set according to other parameters. It should be noted that the execution timing of step S104 may be changed, and it may be moved forward or backward, as long as step S104 can be executed before steps S107 to S112.
Further, in step S105, if the controller determines that the indoor temperature is less than the preset low temperature threshold, the operation mode of the air conditioner is set to a heating mode; at this time, the controller needs to compare the outdoor temperature with the third preset temperature and the fourth preset temperature so as to set the target operating temperature according to the outdoor temperature. It should be noted that, the present invention does not limit any way of determining the target operating temperature according to the outdoor temperature, for example, the outdoor temperature and the target operating temperature may be in a one-to-one correspondence relationship, that is, each outdoor temperature corresponds to one target operating temperature; the outdoor temperature may be substituted into the relational expression to calculate the only target operating temperature, and of course, these setting manners are not restrictive, and a technician may set the setting manner of the target operating temperature according to actual use requirements. As can be understood by those skilled in the art, the specific values of the third preset temperature and the fourth preset temperature can be set by the skilled person according to the actual use requirement; preferably, the third preset temperature is 5 ℃ and the fourth preset temperature is 15 ℃.

In addition, it can be understood by those skilled in the art that the fourth temperature can be determined by other methods, for example, calculation by a relational expression, etc., and those skilled in the art can set the setting method of the fourth temperature according to actual use requirements.
Further, in step S108, if the controller determines that the outdoor temperature is greater than the third preset temperature and less than the fourth preset temperature, the target operating temperature of the air conditioner is set to a sixth temperature, and in the preferred embodiment, the sixth temperature is equal to a second coefficient multiplied by the outdoor temperature plus a second constant. Preferably, the second coefficient is 2/5, the second constant is 14; of course, a technician may set specific values of the second coefficient and the second constant according to actual use requirements, as long as the sixth temperature obtained when the outdoor temperature is between the third preset temperature and the fourth preset temperature is between the fourth temperature and the fifth temperature. In addition, it can be understood by those skilled in the art that the sixth temperature can be determined by other manners, for example, the sixth temperature can also be calculated by other relational expressions, which can be an empirical formula or a modeled data, or the sixth temperature can also be a fixed value, that is, a setting manner of the sixth temperature can be set by a skilled person according to actual use requirements.
Further, in step S109, if the controller determines that the outdoor temperature is greater than or equal to the fourth preset temperature, the target operating temperature of the air conditioner is set to a fifth temperature; wherein the fifth temperature is greater than the fourth temperature. Preferably, the fifth temperature is 20 ℃; of course, the technician may set the specific value of the fifth temperature according to the actual use requirement. It can be understood by those skilled in the art that the fifth temperature can be determined by other methods, for example, calculation by a relational expression, etc., and the setting method of the fifth temperature can be set by those skilled in the art according to actual use requirements.
Further, in step S106, if the controller determines that the indoor temperature is greater than the preset high temperature threshold, the operation mode of the air conditioner is set to be a cooling mode; at this time, the controller needs to compare the outdoor temperature with the first preset temperature and the second preset temperature so as to set the target operating temperature according to the outdoor temperature. It should be noted that, the present invention does not limit any way of determining the target operating temperature according to the outdoor temperature, for example, the outdoor temperature and the target operating temperature may be in a one-to-one correspondence relationship, that is, each outdoor temperature corresponds to one target operating temperature; the outdoor temperature may be substituted into the relational expression to calculate the only target operating temperature, and of course, these setting manners are not restrictive, and a technician may set the setting manner of the target operating temperature according to actual use requirements. As can be understood by those skilled in the art, the specific values of the first preset temperature and the second preset temperature can be set by the skilled in the art according to actual use requirements; preferably, the first preset temperature is 28 ℃ and the second preset temperature is 35 ℃.
Further, in step S110, if the controller determines that the outdoor temperature is less than or equal to the first preset temperature, the target operating temperature of the air conditioner is set to a first temperature. Preferably, the first temperature is 26 ℃; of course, the technician can set the specific value of the first temperature according to the actual use requirement. In addition, it can be understood by those skilled in the art that the first temperature can be determined by other methods, for example, calculation by a relational expression, etc., and those skilled in the art can set the setting method of the first temperature according to actual use requirements.
Further, in step S111, if the controller determines that the outdoor temperature is greater than the first preset temperature and less than the second preset temperature, the target operating temperature of the air conditioner is set to a third temperature, and in the preferred embodiment, the third temperature is equal to a first coefficient multiplied by the outdoor temperature plus a first constant. Preferably, the first coefficient is 4/7, the first constant is 10; of course, a technician may set the specific values of the first coefficient and the first constant according to actual use requirements, as long as the third temperature obtained when the outdoor temperature is between the first preset temperature and the second preset temperature is between the first temperature and the second temperature. In addition, it can be understood by those skilled in the art that the third temperature can be determined by other means, for example, the third temperature can be calculated by other relational expressions, which can be an empirical formula or a model data, or the third temperature can be a fixed value, that is, the setting of the third temperature can be set by those skilled in the art according to actual use requirements.
Further, in step S112, if the controller determines that the outdoor temperature is greater than or equal to the second preset temperature, setting the target operating temperature of the air conditioner to be a second temperature; wherein the second temperature is greater than the first temperature. Preferably, the second temperature is 30 ℃; of course, the technician can set the specific value of the second temperature according to the actual use requirement. It can be understood by those skilled in the art that the second temperature can be determined by other methods, for example, calculation by a relational expression, etc., and the setting method of the second temperature can be set by those skilled in the art according to the actual use requirement.
