Specifically, the set flow rate can be set according to the heat dissipation capacity of the second heat exchanger required for satisfying the foot warming requirement. The flow of the refrigerant flowing through the first heat exchanger is controlled to be less than or equal to the set flow, so that the flow of the refrigerant flowing through the second heat exchanger for heat dissipation can reach a specific value, the heat dissipation capacity of the second heat exchanger can reach the heat dissipation capacity required by foot warming, and the foot warming effect is improved.
The set flow rate may be specifically set according to the current indoor ambient temperature, the set temperature of the air conditioner, and the like. The larger the temperature difference between the indoor environment temperature and the set temperature is, the larger the foot warming requirement is, the smaller the corresponding settable flow is, and the heat dissipating capacity of the second heat exchanger can effectively ensure the heat dissipating capacity of the lower air outlet required by foot warming.
In order to further improve the heating efficiency of the air outlet corresponding to the second heat exchanger to the lower part of the space and further improve the warm-foot effect, the refrigerant flow regulating module can be controlled to regulate the refrigerant flow flowing through the first heat exchanger to 0, all the refrigerants flow through the second heat exchanger to dissipate heat, so that the heat dissipation capacity of the second heat exchanger is maximized, and the heat exchange efficiency of the lower part of the space is guaranteed to be maximized. Specifically, when refrigerant flow control module and first heat exchanger were established ties, steerable refrigerant flow control module was closed, was not allowed the refrigerant to circulate in the branch road at first heat exchanger place, and all high temperature refrigerants all dispel the heat through the second heat exchanger, realized the increase of the heat dissipation capacity of second heat exchanger, guaranteed that the air-out of the air outlet that the second heat exchanger corresponds can satisfy warm sufficient required heat.
Based on this, when the heat exchange regulation module further includes a first air outlet regulation module disposed corresponding to the first heat exchanger, referring to fig. 5, after step S10, the method further includes:
and when the indoor environment temperature and the first temperature meet the set conditions required by foot warming, executing step S20a, and controlling the first air outlet adjusting module to reduce the air outlet volume of the air outlet corresponding to the first heat exchanger to be less than or equal to the set threshold value.
Specifically, when the first air outlet adjusting module comprises a fan corresponding to the first heat exchanger, the rotating speed of the fan can be controlled to be reduced, so that the air output of the air outlet corresponding to the first heat exchanger is reduced. When the first air outlet adjusting module comprises the air guide part arranged at the air outlet corresponding to the first heat exchanger, the air guide part can be controlled to adjust the air guide position, so that the air outlet area of the air outlet corresponding to the first heat exchanger is reduced, and the air outlet volume of the air outlet is reduced. When the first air outlet adjusting module simultaneously comprises the fan corresponding to the first heat exchanger and the air guide component arranged at the air outlet corresponding to the first heat exchanger, the operation of the first air outlet adjusting module can be simultaneously controlled according to the above mode so as to reduce the air output of the air outlet corresponding to the first heat exchanger to be below the set threshold value.
The sequence of the steps S20a and S21 may not be limited, and may be executed synchronously or sequentially. Specifically, step S20a may be executed after step S21, and step S21 may be executed to obtain a coil temperature of the first heat exchanger, determine a target parameter of the operation of the first air-out adjusting module based on the obtained coil temperature, and adjust the operation of the first air-out adjusting module according to the determined target parameter, so that the air-out adjusting function of the first air-out adjusting module and the heat dissipation function of the first heat exchanger may be matched to achieve the heat dissipation capacity of the first heat exchanger required for heating the indoor environment.
The setting threshold may be specifically set according to the current indoor ambient temperature, the setting temperature of the air conditioner, the above-mentioned setting flow rate, and the like. In order to ensure the heat exchange effect of the air conditioner and prevent the air which does not exchange heat sufficiently from being blown out from the air outlet corresponding to the first heat exchanger, when the refrigerant flow regulating module is controlled to regulate the flow of the refrigerant flowing through the first heat exchanger to 0, the first air outlet regulating module can be controlled to reduce the air outlet amount of the air outlet corresponding to the first heat exchanger to 0 (for example, the air guide component arranged at the air outlet corresponding to the first heat exchanger can be controlled to close the air outlet, and the rotating speed of the fan correspondingly arranged at the first heat exchanger can also be controlled to be 0).
In this embodiment, when the temperature of indoor ambient temperature and second heat exchanger satisfied warm sufficient required settlement condition, not only reduce the refrigerant flow of flowing through first heat exchanger through refrigerant flow control module, realize the increase of the radiating refrigerant flow of second heat exchanger of flowing through, but also reduce the air output of the air outlet that first heat exchanger corresponds through first air-out control module in step, thereby realize reducing the heat dissipation capacity of the air outlet that first heat exchanger corresponds, guarantee when full play air conditioner's heat exchange efficiency that the air of not fully exchanging heat can not blow off from the air outlet that first heat exchanger corresponds, maintain indoor whole travelling comfort when guaranteeing warm sufficient effect promotion.
Further, based on the above embodiments, another embodiment of the air conditioner control method of the present application is provided. In this embodiment, referring to fig. 6, when the indoor ambient temperature and the first temperature satisfy the setting condition required for warming feet, before step S21, the method further includes:
step S201, determining the temperature difference between the indoor environment temperature and the set temperature;
the set temperature refers to a target temperature required to be reached by the indoor environment, and can be obtained by acquiring the setting parameters of the air conditioner of the user. The temperature difference here specifically refers to an absolute value of a difference between the indoor ambient temperature and the set temperature.
Step S202, judging whether the temperature difference is larger than or equal to a set threshold value;
when the temperature difference is greater than or equal to a set threshold, performing step S21; and executing step S203 and step S204 when the temperature difference is smaller than the set threshold.
The set threshold value can be specifically set based on actual conditions such as the size of the warm foot comfort temperature and the basic requirement of the user for heating the indoor environment. The temperature difference is greater than or equal to the set threshold, which can indicate that the foot warming requirement of the user is large; a temperature difference less than the set threshold may indicate that the foot warming requirement of the user is relatively small.
Step S203, determining the refrigerant adjusting quantity of the refrigerant flow adjusting module according to the temperature difference;
the refrigerant adjustment amounts corresponding to different temperature differences are different, specifically, the larger the temperature difference is, the larger the foot warming requirement is, the larger the corresponding refrigerant adjustment amount can be, so that the increase amount of the refrigerant for heat dissipation of the second heat exchanger is increased. The relationship (which may be a mapping relationship, a calculation formula, etc.) between the temperature difference and the refrigerant adjustment amount is established in advance. Based on the relationship, the refrigerant adjustment amount corresponding to the current temperature difference is determined. Specifically, the temperature difference may be divided into a plurality of value intervals, and each value interval corresponds to a set refrigerant adjustment amount. And determining the section of the current temperature difference, and taking the set refrigerant adjustment quantity corresponding to the section as the refrigerant adjustment quantity of the refrigerant flow adjusting module. In addition, the temperature difference can also be directly substituted into a preset formula, and the current refrigerant adjustment quantity of the refrigerant flow adjusting module is obtained through calculation.
Step S204, controlling the refrigerant flow regulating module to reduce the flow of the refrigerant flowing through the first heat exchanger according to the refrigerant regulating quantity so as to increase the flow of the refrigerant flowing through the second heat exchanger for heat dissipation.
Specifically, the opening degree of the refrigerant flow regulating module is controlled according to the refrigerant regulating quantity, so that the reduction range of the refrigerant flow flowing through the first heat exchanger is the obtained refrigerant regulating quantity, and the increase range of the flow of the refrigerant radiated by the second heat exchanger is the obtained refrigerant regulating quantity.
In this embodiment, a regulation and control mode of the refrigerant flow regulation module is selected based on a difference between an indoor environment temperature and a set temperature, wherein when the temperature difference is greater than or equal to a set threshold value, it indicates that a foot warming requirement is large, and a heat exchange amount of an air outlet corresponding to a second heat exchanger required by the foot warming needs to be preferentially ensured, so that the refrigerant flow regulation module is directly controlled to reduce the refrigerant flow passing through the first heat exchanger to be lower than the set flow, thereby effectively improving the heat exchange efficiency of the air outlet corresponding to the second heat exchanger located at the lower part, and realizing the improvement of the foot warming effect; when the temperature difference is smaller than a set threshold value, the requirement for warming feet is relatively small, the refrigerant flow adjusting module is controlled based on the refrigerant adjusting quantity determined by the temperature difference, so that the first heat exchanger and the second heat exchanger can simultaneously exchange heat to meet the requirements of the whole thermal comfort of the indoor environment and the like, and meanwhile, the heat dissipating quantity of the air outlet corresponding to the second heat exchanger is ensured to realize that the temperature of the lower part of the space can reach the comfort temperature required by feet of a user.
Further, based on any of the above embodiments, a further embodiment of the air conditioner control method of the present application is provided. Specifically, referring to fig. 7, before step S20, the method further includes:
step S11, determining whether the indoor environment temperature is within a set temperature range, and determining whether the first temperature is greater than or equal to a first temperature threshold;
when the indoor environment temperature is in the set temperature interval and the first temperature is greater than or equal to the first temperature threshold, performing step S12; when the indoor environment temperature is outside the set temperature range, or the first temperature is less than the first temperature threshold, step S13 is executed.
The set temperature interval may be divided based on a minimum limit value of the indoor ambient temperature that satisfies the user's foot warming demand. The temperature less than or equal to the minimum limit value is divided into set temperature intervals. Based on this, indoor environment temperature is located the temperature range of setting for, shows that indoor environment can't satisfy user's warm foot demand, can adopt further air conditioner regulation and control to improve the realization of warm foot effect in order to guarantee the space lower part temperature. When the indoor environment temperature is outside the set temperature interval (i.e. when the indoor environment temperature is greater than the minimum limit value), the indoor environment can be considered to meet the foot warming requirement of the user, and foot warming is not needed.
The first temperature threshold may be determined based on a minimum amount of heat dissipation required by the second heat exchanger for foot comfort requirements. The first temperature is greater than or equal to a first temperature threshold value, which indicates that the current heat dissipation capacity of the second heat exchanger can meet the basic requirement of foot warming; the first temperature is lower than the first temperature threshold value, which indicates that the current heat dissipation capacity of the second heat exchanger can not meet the basic requirement of foot warming.
The set temperature interval and the first temperature threshold may be preset fixed parameters. In addition, based on the current indoor environment temperature, the set temperature, the height of the air outlet corresponding to the second heat exchanger from the ground, the air outlet parameters (such as air outlet temperature and/or air outlet direction) of the air outlets corresponding to the first heat exchanger and the second heat exchanger, and the like, the set temperature interval and the first temperature threshold value are selected from more than one preconfigured parameters, so that the set conditions required by foot warming are determined by integrating the influence of the factors on the foot comfort, the accurate judgment of whether the current working condition of the air conditioner meets the set conditions required by foot warming is realized, the air conditioner is further regulated and controlled in time, and the foot comfort requirement of a user can be met by improving the operation of the air conditioner.
Step S12 of determining that the indoor ambient temperature and the first temperature satisfy the setting condition;
step S13, determining that the indoor ambient temperature and the first temperature do not satisfy the setting condition.
In this embodiment, the set temperature interval and the first temperature threshold are respectively used as the reference of whether the indoor ambient temperature and the temperature of the second heat exchanger meet the set conditions required by the warm foot, so that whether the current operation condition of the air conditioner meets the set conditions required by the warm foot is accurately judged.
Further, the step of determining whether the indoor environment temperature is within the set temperature range in step S11 includes: judging whether the indoor environment temperature is smaller than or equal to a second temperature threshold and larger than or equal to a third temperature threshold; wherein the third temperature threshold is less than the second temperature threshold; when the indoor environment temperature is smaller than or equal to the second temperature threshold and larger than or equal to the third temperature threshold, determining that the indoor environment temperature is in the set temperature range; and when the indoor environment temperature is greater than the second temperature threshold value, or the indoor environment temperature is less than the third temperature threshold value, determining that the indoor environment temperature is outside the set temperature interval.
Here, the set temperature section is divided based on the second temperature threshold and the third temperature threshold, and each of values between the second temperature threshold and the third temperature threshold may be divided into the set temperature section. When the indoor environment temperature is higher than the second temperature threshold, the indoor environment can meet the foot warming requirement of the user, further foot warming regulation and control are not needed, and the phenomenon that the lower part temperature is too high to influence the comfort of the user and influence the overall heat exchange efficiency of the indoor environment is avoided; when the indoor environment temperature is less than or equal to the second temperature threshold and greater than or equal to the third temperature threshold, the indoor environment can meet the basic heating requirement, meanwhile, the indoor environment can not meet the foot warming requirement of the user, and the temperature of the lower part of the space can be further regulated and controlled by an air conditioner to ensure the realization of the foot warming effect; when the indoor environment temperature is smaller than the third temperature threshold value, the basic heating requirement cannot be guaranteed in the current indoor environment, the thermal comfort of a user is seriously influenced, the heating effect cannot be achieved even if the heat exchange quantity of the second heat exchanger is increased, the current matched heating state of the first heat exchanger and the second heat exchanger is maintained, and the indoor heating requirement is preferentially guaranteed.
Based on this, just increase the heat dissipation capacity of the air outlet that the second heat exchanger corresponds when indoor ambient temperature is located between two temperature threshold values to the realization is warm sufficient. Otherwise, based on indoor environment's actual heat transfer demand, control heat transfer adjusting module realizes that the air outlet that first heat exchanger corresponds and the synchronous air-out of the air outlet that the second heat exchanger corresponds, and first heat exchanger heats the air with the second heat exchanger in step, can guarantee indoor basic heat demand when the temperature is low excessively, realizes the improvement of the whole travelling comfort of indoor environment, can avoid the space lower part temperature to excessively improve when the temperature is too high, avoids excessively dispelling the heat and leads to the reduction of warm sufficient effect.
Further, when the heat exchange adjusting module includes a first heat exchange adjusting module and a second heat exchange adjusting module, the first heat exchange adjusting module corresponds to the first heat exchanger, and the second heat exchange adjusting module corresponds to the second heat exchanger, after step S20, the method further includes:
exiting the first mode when the current temperature of the indoor environment is greater than or equal to a fourth temperature threshold, or the current temperature of the second heat exchanger is less than or equal to a fifth temperature threshold, or a command for exiting the first mode is received; wherein the fourth temperature threshold is greater than the second temperature threshold, and the fifth temperature threshold is less than the first temperature threshold.
The current temperature of the indoor environment is greater than or equal to the fourth temperature threshold value, which indicates that the indoor environment can meet the foot warming requirement of the user, and the air conditioner is not needed to further warm the foot. The current temperature of the second heat exchanger is smaller than or equal to the fifth temperature threshold, which indicates that the heat dissipation capacity of the current second heat exchanger cannot ensure that the heat dissipation capacity of the corresponding air outlet can meet the basic requirement of foot warming. When an instruction to exit the first module is received, it indicates that the user no longer needs to warm the foot. When any one of the three conditions is met, the requirement for comfort of warming the foot can be met or the foot warming effect can not be achieved through further regulation temporarily, so that the first mode can be exited, and the relevant regulation of warming the foot is not executed any more. Specifically, after the first mode is exited, the first heat exchange adjusting module can be controlled to operate according to the current temperature of the first heat exchanger and the indoor environment temperature, and the second heat exchange adjusting module can be controlled to operate according to the current temperature of the second heat exchanger and the indoor environment temperature, so that the overall heat exchange requirement of the indoor environment is met. If none of the three conditions can be met, the method returns to step S10 to continue to perform the related control of foot warming.
Wherein the value range of the first temperature threshold is [20 ℃, 40 ℃; the value range of the second temperature threshold is [20 ℃, 30 ℃; the value range of the third temperature threshold is [10 ℃, 20 ℃; the value range of the fourth temperature threshold is [20 ℃, 30 ℃; the value range of the fifth temperature threshold is [10 ℃, 30 ℃). Specifically, in this embodiment, the first temperature threshold may be specifically 26 ℃, the second temperature threshold may be specifically 25 ℃, the third temperature threshold may be specifically 15 ℃, the fourth temperature threshold may be specifically 26 ℃, and the fifth temperature threshold may be specifically 20 ℃.
