Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
When the air conditioner is used, a user can set the temperature through the remote controller or the intelligent terminal, the air conditioner runs, the air conditioner can acquire the temperature of the air return inlet and the temperature set by the user, difference comparison is carried out between the air return inlet and the temperature set by the user, the absolute value of the difference is smaller than the temperature compensation value, the set temperature is considered to be reached, and the compressor is subjected to frequency reduction or shutdown.
However, in practical applications, due to the influence of factors such as the actual installation environment of the air conditioner, a certain deviation exists between the temperature of the air outlet and the temperature sensed by the user, which may cause the control strategy of the compressor to be inaccurate and affect the actual comfort of the user. For example, in the case of a wall-mounted air conditioner, since the installation position is high, cold air sinks during cooling, and the temperature of an air return opening is often higher than that of an indoor user activity area; when heating, the hot air floats upwards, and the temperature at the air return opening is generally higher than that of the active area of a user. Even if the deviation between the two is reduced through temperature compensation, the difference between the return air inlet temperature and the temperature required by a user cannot be really reflected due to the difference of the actual installation environment of the air conditioner because the temperature compensation value is fixed.
In order to solve the above problem, an embodiment of a first aspect of the present invention provides a method for controlling an air conditioner, where the method may dynamically adjust a temperature compensation value, meet a requirement of a user on an actual sensible temperature, and is suitable for an actual installation environment of the air conditioner, so as to improve comfort.
An air conditioner control method according to an embodiment of the present invention is described below with reference to fig. 1.
As shown in fig. 1, which is a flowchart of an air conditioner control method according to an embodiment of the present invention, the air conditioner control method of an embodiment of the present invention includes at least the following steps S1-S5, as shown in fig. 1. The execution sequence of the following steps is not limited by the step symbols, and can be adjusted according to the actual situation if necessary.
And S1, receiving the actual body feeling temperature demand information of the user.
The user actual somatosensory temperature demand information can include that the user's heat demand is lower or the user's cold demand is higher in current somatosensory under the current indoor environment, and when the user needs, the user can express the actual somatosensory temperature demand through adjusting the set temperature or other modes, so that the user actual somatosensory temperature demand information is generated.
In some embodiments, the air conditioner receives an instruction for adjusting the set temperature, and determines the temperature increase demand or the temperature decrease demand of the user according to the instruction. For example, when the sensible temperature of the user is low, the set temperature can be increased through the remote controller or the intelligent terminal, or when the sensible temperature of the user is high, the set temperature can be decreased through the remote controller or the intelligent terminal, and then the set temperature is sent to the air conditioner, namely the air conditioner receives the actual sensible temperature demand information of the user.
In other embodiments, the air conditioner receives multimedia information of cold and hot feelings of a user, and determines the heating requirement or the cooling requirement of the user according to the multimedia information. For example, a voice recognition module is arranged on the air conditioner, and receives voice information of cold and hot feelings fed back by a user through the voice recognition module, or an image recognition module is arranged to determine actions of the cold and hot feelings of the user through image recognition, namely, the information of the actual temperature sensing requirement of the user is acquired.
And S2, acquiring the temperature of the return air inlet, the original temperature compensation value and the original set temperature.
Wherein, can set up temperature sensor in the return air inlet department of air conditioner and detect the return air inlet temperature. The original set temperature can be an initial set temperature set by a user through a remote controller or an intelligent terminal, and can also be a set temperature of a previous period in a control strategy operation period. Likewise, the original temperature compensation value may be an initially set temperature compensation value or a temperature compensation value determined in a previous cycle within the control strategy operation cycle.
And S3, obtaining the original target temperature according to the original set temperature and the original temperature compensation value.
Specifically, in the cooling mode, because the cold air sinks, and the temperature of the return air inlet is higher than the temperature of the indoor personnel activity area, the original target temperature can be the sum of the original set temperature and the original temperature compensation value, and the temperature of the return air inlet is less than or equal to the sum, namely the air conditioner is considered to reach the target temperature; in the heating mode, because the hot air rises, the temperature of the return air inlet is also higher than the temperature of the indoor personnel activity area, therefore, the original target temperature can be the sum of the original set temperature and the original temperature compensation value, and the temperature of the return air inlet is greater than or equal to the difference, namely the air conditioner is considered to reach the target temperature.
And S4, obtaining a target temperature compensation value according to the current operation mode of the air conditioner, the actual body feeling temperature demand information of the user, the return air inlet temperature and the original target temperature.
And S5, controlling the running frequency of the compressor according to the target temperature compensation value.
Specifically, in the embodiment of the present invention, the temperature compensation value is no longer fixed, but is automatically adjusted based on the actual operating environment of the air conditioner, i.e., a timely temperature compensation value is obtained.
The actual body sensing temperature demand information of the user can determine the body sensing cold and heat condition of the user, namely the temperature rise or temperature reduction demand, under the current environment temperature. The direction of temperature adjustment can be determined based on the current operation mode and the actual sensible temperature demand information of the user, for example, the user feels hot in the refrigeration mode, and the refrigeration degree needs to be increased, whereas the user feels cold in the refrigeration mode, and the refrigeration degree needs to be decreased. The relationship between the temperature of the return air inlet and the original target temperature can influence the running state of the compressor, thereby influencing the refrigeration or heating effect.
In the embodiment of the invention, the temperature compensation value is adaptively and dynamically adjusted by combining the current operation mode, the actual sensible temperature demand information of the user, the temperature of the air return inlet and the original target temperature, and the dynamic temperature compensation value is adopted to control the operation state of the compressor, such as increasing the operation frequency, reducing the operation frequency or stopping the compressor, so that the method and the device are suitable for the actual installation environment of the air conditioner, the size of a room, the sunshine condition and other actual conditions, the actual sensible temperature demand of the user is met, and the comfort is improved.
The following describes the process of dynamically adjusting the temperature compensation value in different operation modes in the embodiment.
In an embodiment, in step S4, obtaining a target temperature compensation value according to the current operation mode, the user actual sensible temperature demand information, the return air inlet temperature, and the original target temperature, which may include the following several cases.
The method comprises the steps of determining a current operation refrigeration mode, determining that a user has a cold demand according to actual sensible temperature demand information of the user, reducing an original temperature compensation value by a first temperature amplitude value to obtain a target temperature compensation value if the temperature of a return air inlet is smaller than or equal to an original target temperature, and controlling the operation frequency of a compressor according to the target temperature compensation value.
For example, when the air conditioner is operated in a refrigerating mode, cold air sinks, the original target temperature is a sum value of the original set temperature and the original temperature compensation value, when a user reduces the set temperature, the user feels hot, the return air inlet temperature is compared with the original target temperature, the return air inlet temperature is smaller than or equal to the original target temperature, the air conditioner is considered to reach the original set temperature, the user feels hot, the original temperature compensation value is reduced by A, the return air inlet temperature is larger than the original target temperature, namely the air conditioner is considered not to reach the user set temperature, the air conditioner is enabled to continue refrigerating, the refrigerating capacity is improved, the refrigerating speed is accelerated, and the cold requirement of the user is met.
Embodiment 2, a current operation refrigeration mode is determined, it is determined that a user has a cold demand according to information of the actual sensible temperature demand of the user, if the temperature of the air outlet is higher than an original target temperature, an original temperature compensation value is used as a target temperature compensation value, and the operation frequency of the compressor is controlled according to the target temperature compensation value.
For example, during the cooling operation, when the user lowers the set temperature, the user feels hot, the air return temperature is compared with the original target temperature, the air outlet temperature is higher than the original target temperature, namely, the air conditioner does not reach the original set temperature, the air conditioner continues to perform the cooling operation, the original temperature compensation value is kept unchanged, the operation frequency of the compressor is increased, the cooling capacity is increased, the cooling speed is increased, and the cooling requirement of the user is met.
Embodiment 3, determine the current operation refrigeration mode, and, determine that the user has a heat demand according to user's actual sensible temperature demand information, if the return air inlet temperature is greater than the original target temperature, increase the original temperature compensation value by the second temperature amplitude to obtain a target temperature compensation value, and control the operating frequency of the compressor according to the target temperature compensation value.
For example, when the air conditioner is operated in a refrigerating mode, the original target temperature is a value obtained by summing the original set temperature and the original temperature compensation value, when the original set temperature is increased by a user, the user feels cold, the return air inlet temperature is compared with the original target temperature, the return air inlet temperature is higher than the original target temperature, namely, the air conditioner is operated in a refrigerating mode, and the user feels cold, the air conditioner needs to be stopped to refrigerate as soon as possible, so that the original temperature compensation value is increased by A, the air conditioner can reach the original set temperature as soon as possible, the frequency of the compressor is reduced or the air conditioner is stopped, the indoor temperature is increased, the heat requirement of the user is met, and the comfort is improved.
Embodiment 4, confirm the current operation refrigeration mode to and, confirm that the user has the heat demand according to user's actual body feeling temperature demand information, if return air temperature is less than or equal to former target temperature, regard original temperature compensation value as target temperature compensation value, and according to the operating frequency of target temperature compensation value control compressor.
For example, when the air conditioner is in refrigeration operation, a user increases the set temperature to indicate that the user feels cold, the return air temperature is compared with the original target temperature, if the temperature of the return air inlet is less than or equal to the original target temperature, the air conditioner reaches the original set temperature, the current temperature compensation value is maintained, namely the original temperature compensation value is not adjusted, and the frequency of the compressor is reduced or the air conditioner is stopped, so that the purpose of increasing the indoor temperature is achieved, the heat requirement of the user is met, and the comfort is improved.
Embodiment 5, determine the current operation heating mode, and determine that the user has a heat demand according to the information of the user's actual sensible temperature demand, if the return air inlet temperature is less than the original target temperature, use the original temperature compensation value as the target temperature compensation value, and control the operating frequency of the compressor according to the target temperature compensation value.
For example, the air conditioner is in heating operation, hot air rises, the original target temperature is the sum of the original set temperature and the original temperature compensation value, when the set temperature is increased by a user, the user feels that the user feels insufficient heat, the return air inlet temperature and the original target temperature are compared, if the return air inlet temperature is smaller than the original target temperature, namely the air conditioner continues to heat according to the original program, the original temperature compensation value is kept unchanged, meanwhile, the operation frequency of the compressor is increased, the heating speed is increased, the heat requirement of the user is met, and the comfort is improved.
Embodiment 6, determine the current operation heating mode, and determine that the user has a heat demand according to the information of the actual sensible temperature demand of the user, if the temperature of the return air inlet is greater than or equal to the original target temperature, increase the original temperature compensation value by a third temperature amplitude value to serve as a target temperature compensation value, and control the operation frequency of the compressor according to the target temperature compensation value.
For example, the air conditioner operates a heating mode, when a user increases a set temperature, it indicates that the user feels insufficient heat, the return air inlet temperature is compared with an original target temperature, if the return air inlet temperature is greater than or equal to the original target temperature, that is, the air conditioner reaches the original set temperature, in order to meet the heat requirement of the user, the air conditioner needs to continue heating, an original temperature compensation value is increased by B, so that the air conditioner does not meet the condition of reaching the set temperature, thereby continuing to operate and heat, improving the operating frequency of the compressor, increasing the heating speed, meeting the heat requirement of the user, and improving the comfort.
Embodiment 7, determine the current operation heating mode, and determine that the user has a cold demand according to the information of the actual sensible temperature demand of the user, if the temperature of the return air inlet is less than the original target temperature, reduce the original temperature compensation value by the fourth temperature amplitude value to obtain a target temperature compensation value, and control the operation frequency of the compressor according to the target temperature compensation value.
For example, the air conditioner operates in a heating mode, when a user lowers a set temperature, the user feels that the air conditioner is too hot, the return air inlet temperature is compared with an original target temperature, if the return air inlet temperature is smaller than the original target temperature, the air conditioner is considered not to reach the original set temperature, the air conditioner continues to operate in a heating mode according to an original temperature compensation value, in order to meet the cold requirement of the user, the original temperature compensation value is reduced by B, the air conditioner reaches the original set temperature as soon as possible, the operation frequency of a compressor is reduced or the air conditioner is shut down, the indoor temperature is gradually reduced, the cold requirement of the user is met, and the comfort is improved.
Embodiment 8, determine the current operation heating mode, and determine that the user has a cold demand according to the information of the actual sensible temperature demand of the user, if the temperature of the return air inlet is greater than or equal to the original target temperature, take the original temperature compensation value as the target temperature compensation value, and control the operation frequency of the compressor according to the target temperature compensation value.
For example, in the air conditioner operation heating mode, when a user lowers a set temperature, the user feels too hot, the return air inlet temperature is compared with an original target temperature, if the return air inlet temperature is greater than or equal to the original target temperature, the air conditioner reaches the original set temperature, the air conditioner stops heating operation, an original temperature compensation value is kept unchanged, the operation frequency of the compressor is reduced or the air conditioner is stopped, the indoor temperature is gradually reduced, the cold requirement of the user is met, and the comfort is improved.
It should be noted that, the first temperature amplitude, the second temperature amplitude, the third temperature amplitude, and the fourth temperature amplitude mentioned above may be equal or unequal, and may be set according to specific situations, and are not limited specifically herein.
In summary, the air conditioner control method of the embodiment of the invention obtains the actual sensible temperature requirement of the user, and dynamically adjusts the temperature compensation value with the return air inlet temperature and the original target temperature, thereby better determining the temperature and cold feeling of the user, solving the problems that the existing temperature compensation value is fixed, different air conditioner installation environments and different preferences of the user on the temperature can not meet the requirement of the user, and improving the comfort.
