In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a temperature adjustment time control method for an air conditioner according to an embodiment of the present disclosure is shown, where the method is applied to a controller of the air conditioner, where the air conditioner may be a household air conditioner, a vehicle air conditioner, an industrial air conditioner, or the like.
As shown in fig. 1, the method may include the steps of:
and S110, acquiring the air heat exchange coefficient of the current space.
The present space refers to a room where an air conditioner is installed, a vehicle interior, and the like, and the room is described herein as an example.
The heat exchange coefficient of air is related to the room area, window area, orientation, home furnishings and the like, so that the heat exchange coefficients of air in different rooms are different.
In one embodiment of the present application, the heat exchange coefficient of the air in the room is calculated by using a large amount of historical operating data of the air conditioner in the room according to the fact that the heat exchange amount of the refrigerant is equal to the heat exchange amount of the air in the room.
Wherein, the formula of the heat exchange amount is as follows: q = K Q Δ T, where Q is the heat exchange amount, K is the heat exchange coefficient, Q is the flow rate, Δ T is the temperature difference, and Δ T is the time difference.
According to the energy conservation, the heat exchange quantity of the refrigerant of the air conditioner is equal to the heat exchange quantity of indoor air, Q Air (a) ＝Q Refrigerant I.e. K Refrigerant *q Refrigerant *△T Refrigerant *△t Refrigerant ＝K Air (W) *q Air (a) *△T Air (a) *△t Air (W) Further based on the equation:
in formula 1, K Refrigerant The parameters are inherent parameters of the refrigerant and are obtained according to the record of the system;
△T refrigerant As a refrigerantThe temperature difference between the initial temperature and the set temperature, and the temperature of the refrigerant can be measured by a coil pipe temperature sensor of the liquid inlet pipe and the liquid outlet pipe;
△t refrigerant For the time required by the refrigerant to be reduced from the initial temperature to the set temperature, a timer in the air conditioner can record the time when the temperature of the refrigerant reaches the set temperature;
q refrigerant The frequency of the compressor in the air conditioner is positively correlated, and the frequency can be calculated according to the frequency of the compressor;
△t air (a) ＝△t Refrigerant ；
△T Air (W) The air conditioner temperature sensor can detect the air conditioner temperature;
q air (W) The air volume of the air conditioner is equal to the product of the air outlet air speed and the air outlet area, the air outlet air speed is the air conditioner air speed, and the air outlet area of the air conditioner is fixed for a specific air conditioner, therefore, q is Air (W) Can be obtained by calculation;
the data can be directly acquired or calculated through the directly acquired data, so that the air heat exchange coefficient of the room can be calculated according to the historical operating data of the air conditioner.
In another embodiment of the application, the air heat exchange coefficients of the room at different times are respectively calculated according to historical operating data of the same room at different times, and the average value of the air heat exchange coefficients at different times is further calculated to obtain the final air heat exchange coefficient corresponding to the room.
After the air heat exchange coefficient of the room is obtained, the air heat exchange coefficient of the room can be stored in a memory of the air conditioner, and the controller can directly read the air heat exchange coefficient from the memory every time the cooling time of the air conditioner needs to be controlled.
In addition, the process of obtaining the air heat exchange coefficient can be executed in a standby state, so that the time required by the real-time control of the air conditioner is shortened, and the response speed of the air conditioner is improved.
And S120, acquiring the heat exchange coefficient of a refrigerant of the air conditioner and the current air speed of the air conditioner.
The heat exchange coefficient of the refrigerant of the air conditioner is an inherent parameter, and can be obtained by inquiring in advance according to the refrigerant used by the air conditioner and stored in a controller of the air conditioner.
The current wind speed of the air conditioner refers to the current running wind speed of the air conditioner when the air conditioner is started, and the flow of indoor air can be calculated according to the wind speed of the air conditioner.
In one application scenario, if the user sets the wind speed at startup, the current wind speed is the wind speed set by the user.
In another application scenario, if the user does not set the wind speed, the current wind speed is the default wind speed of the air conditioner, for example, the default wind speed may be the maximum wind speed, or the wind speed operated when the air conditioner is turned off last time, which is not described herein again.
And S130, calculating to obtain the target frequency of the compressor in the air conditioner according to the air heat exchange coefficient, the refrigerant heat exchange coefficient and the current air speed of the air conditioner.
In one embodiment of the present application, as shown in fig. 2, the process of S130 may include the steps of:
and S131, calculating to obtain the air flow of the current space according to the current wind speed of the air conditioner.
The air speed of the air conditioner is positively correlated with the indoor air flow, so that the air flow in the room can be calculated according to the current air speed of the air conditioner.
And S132, calculating the refrigerant flow of the air conditioner according to the air heat exchange coefficient, the air flow and the refrigerant heat exchange coefficient.
According to the law of conservation of energy, Q Air (W) ＝Q Refrigerant I.e. K Refrigerant *q Refrigerant *△T Refrigerant *△t Refrigerant ＝K Air (W) *q Air (W) *△T Air (W) *△t Air (a) 。
The air conditioner has a working principle that a refrigerant (i.e., a refrigerant) is compressed into high-pressure steam by a compressor and then exchanges heat with indoor air to achieve the purpose of reducing the indoor temperature, and the cooling capacity of the refrigerant is the same as that of the indoor air, namely delta T Refrigerant ＝△T Air (W) 。
To make Δ t Refrigerant ＝△t Air (W) It is necessary to make K Refrigerant *q Refrigerant ＝K Air (W) *q Air (a) At K, in Refrigerant 、K Air (a) And q is Air (W) On the premise of knowing, q can be calculated Refrigerant The target value of (2).
And S133, calculating the target frequency of the compressor according to the relation between the refrigerant flow and the frequency of the compressor in the air conditioner.
q Refrigerant Is positively correlated with the frequency of the compressor, so that q can be calculated from the previous step Refrigerant The target frequency of the compressor is calculated.
And S140, controlling the frequency of a compressor in the air conditioner so that the time required for reducing the temperature of the current space by the target cooling value is equal to the temperature reaching time set by a user.
The frequency of the compressor is controlled to a target frequency so that the time required for the temperature in the room to decrease by the user-set temperature decrease value is equal to the user-set temperature reaching time, for example, the user sets 10min for the room temperature to decrease by 8 ℃.
The method for controlling the adjusting time of the air conditioner provided by this embodiment obtains the air heat exchange coefficient of the space where the air conditioner is located, the refrigerant heat exchange coefficient of the air conditioner, and obtains the current air speed of the air conditioner; and then, controlling the frequency of a compressor in the air conditioner according to the air heat exchange coefficient, the refrigerant heat exchange coefficient and the current air speed of the air conditioner, so that the time required for reducing the temperature of the current space by the target cooling value is equal to the temperature reaching time set by a user. According to the fact that the heat exchange amount of the refrigerant is equal to the heat exchange amount of the air, but the heat exchange coefficient of the refrigerant is different from the heat exchange coefficient of the air, the flow rate of the refrigerant can be adjusted to enable the cooling time of the refrigerant to be the same as the air cooling time, and the fact that the cooling time of the refrigerant for reducing the target cooling value in the air conditioner is equal to the temperature reaching time set by a user is achieved.
In one embodiment of the present application, as shown in fig. 3, the process of calculating the target frequency of the compressor may include the steps of:
and S1331, calculating to obtain a first frequency of the compressor according to the relation between the refrigerant flow and the compressor frequency.
According to the positive correlation between the refrigerant flow and the compressor frequency, a compressor frequency value, namely a first frequency, which enables the refrigerant flow to reach a refrigerant flow target value is calculated.
And S1332, comparing the magnitude between the first frequency and the maximum frequency of the compressor.
The maximum frequency of the compressor is the upper limit of the frequency that the compressor can reach and the operating frequency of the compressor cannot exceed the maximum frequency.
And S1333, when the first frequency is less than the maximum frequency, determining the first frequency as the target frequency.
And if the calculated first frequency is less than the maximum frequency, directly determining the calculated first frequency as the target frequency of the final operation of the compressor. That is, in such a scenario, only the frequency of the compressor needs to be adjusted.
And S1334, when the first frequency is greater than the maximum frequency, increasing the wind speed of the air conditioner, recalculating to obtain a new first frequency according to the adjusted wind speed until the new first frequency is less than the maximum frequency, and determining the latest first frequency as the target frequency.
If the calculated first frequency is greater than the maximum frequency of the compressor, it indicates that the compressor cannot meet the target refrigerant flow rate even if the compressor operates at the maximum frequency, so that the rotating speed of the fan in the air conditioner is increased, that is, the air speed of the air conditioner is increased, so as to reduce the operating frequency of the compressor, and a new first frequency of the compressor is recalculated, until the new first frequency is less than the maximum frequency, the air speed of the air conditioner is not adjusted, and the first frequency at the moment is determined to be the target frequency of the compressor, that is, in such a scenario, the compressor frequency and the rotating speed of the fan in the air conditioner need to be adjusted.
In the process of obtaining the target frequency of the compressor provided in this embodiment, after the frequency at which the compressor should operate is obtained through calculation, the frequency is compared with the upper limit value of the frequency of the compressor, if the frequency at which the compressor should operate is greater than the upper limit value of the frequency, the wind speed of the air conditioner is increased, the frequency at which the compressor should operate is recalculated until the frequency at which the compressor should operate is less than the upper limit value of the frequency, the frequency value is determined as the target frequency, and the compressor is controlled according to the target frequency.
