Example 1
The present embodiment provides an air supply control method, which is applied to an air conditioner, fig. 1 is a schematic structural diagram of an air conditioner to which the present invention is applied, as shown in fig. 1, the air conditioner includes an internal unit and an external unit, the internal unit of the air conditioner is communicated with a plurality of indoor spaces 10 through an air supply pipeline 20 and an air port with different lengths, a valve 201 is disposed on the air supply pipeline 20 for controlling an air supply amount, fig. 2 is a flowchart of an air supply control method according to an embodiment of the present invention, as shown in fig. 2, the method includes:
s101, obtaining the temperature changing time required for the air conditioner internal unit pipeline to reach the target temperature when each air supply pipeline is independently conducted; the target temperature is the temperature of the indoor space communicated with the currently conducted pipeline, and the target temperature is different when the temperature change time is detected each time.
The length of the air supply pipeline is the distance that air flows from an air inlet arranged in the indoor space to the indoor unit pipeline, and if the air speed is constant, the time that the indoor air flows from the indoor to the position of the temperature sensing bulb is in direct proportion to the length of the air supply pipeline, so that the length of the air supply pipeline can be reflected by the length of the time that the indoor air flows from the indoor to the position of the temperature sensing bulb.
S102, determining the length of each air supply pipeline according to the acquired temperature change time of each air supply pipeline; wherein the length is proportional to the temperature change time.
Under the condition of a certain wind speed, the time for indoor air to flow from the indoor to the position of the thermal bulb is in direct proportion to the length of the air supply pipeline, so that the length of the air supply pipeline can be reflected by determining the time for the indoor air to flow from the indoor to the position of the thermal bulb, and it needs to be noted that under the condition of a known wind speed, the length of the air supply pipeline can be an actual length calculated according to the wind speed and the temperature change time, or a relative length calculated according to the ratio of the temperature change time of each air supply pipeline, namely, the length of one air supply pipeline is assumed to be 1, and the relative lengths of other air supply pipelines are determined according to the proportional relation.
According to the air supply control method, when each air supply pipeline is independently conducted, the length of the air supply pipeline is determined by obtaining the temperature change time required for the air conditioner internal unit pipeline to reach the same temperature as the indoor space communicated with the currently conducted pipeline, the length of the air supply pipeline can be accurately measured, the air supply parameters can be adjusted adaptively, and the comfort is improved.
Example 2
In this embodiment, another air supply control method is provided, where before determining the length of the pipeline according to the temperature change time, the temperature change time is obtained first, and in order to sequentially obtain the temperature change time of each air supply pipeline, step S101 includes: controlling the air conditioner to run for a first preset time and then closing the air conditioner to enable the pipeline of the air conditioner indoor unit to generate temperature difference with each indoor space; for example, a refrigeration mode can be started, so that the temperature of the indoor unit pipeline and the air supply pipeline is reduced to be lower than the temperature of each indoor space by a certain value, and after a second preset time, the fan of the air conditioner is controlled to rotate reversely, so that indoor hot air flows back to the indoor unit pipeline; then, the valves on the air supply pipelines are sequentially controlled to be opened independently, so that the air supply pipelines are conducted independently, the temperature change time required by the air conditioner indoor unit pipeline based on the same initial temperature change as the target temperature is obtained, similarly, the heating mode can also be started, the temperature of the indoor unit pipeline and the air supply pipeline is increased to be higher than the temperature of each indoor space by a certain value, and the scheme is realized.
Specifically, controlling each blast pipe in turn to independently conduct to obtain the temperature change time required by the air conditioner internal unit pipeline based on the same initial temperature change as the target temperature includes: triggering any one air supply pipeline to be conducted, acquiring the temperature change time of the air conditioner indoor unit pipeline to the target temperature based on the initial temperature change, and recording the initial temperature; the initial temperature is the temperature of the pipeline of the air conditioner indoor unit when the triggering air pipeline is conducted; in order to eliminate the influence of different initial temperatures on the temperature changing time, after the temperature changing time of each pipeline is obtained, the air conditioner is controlled to operate for a third preset time, so that the pipelines of the air conditioner internal unit return to the initial temperature; and after the initial temperature is returned, continuously and sequentially obtaining the temperature changing time of the rest air supply pipelines until the temperature changing time of all the air supply pipelines is obtained.
After the length of the air supply pipeline is determined according to the temperature changing time, in order to adjust the air supply parameters of each air supply pipeline according to the different lengths of the air supply pipeline, after step S102 is executed, the method further includes: adjusting the air supply parameters of each air supply pipeline according to the length of each air supply pipeline; the air supply parameters comprise air supply quantity and air supply speed, and the air supply parameters are positively correlated with the length of the air supply pipeline, namely the longer the length of the air supply pipeline is, the larger the air supply parameters are. This is because the longer the length of the air supply duct is, the smaller the pressure in the duct is, the weaker the wind force is, the shorter the length of the air supply duct is, the larger the pressure in the duct is, and the stronger the wind force is, and therefore, different air supply parameters should be set for the longer duct and the shorter air supply duct, and the longer the duct is, the larger the air supply parameter should be.
When at least two air supply pipelines need to be switched on, the adjusted air supply parameters are the air supply quantity of each air supply pipeline, the air supply quantity of each air supply pipeline can be adjusted through adjusting the opening degree of a valve on the air supply pipeline, specifically, if at least two air supply pipelines need to be switched on, then according to the length of each air supply pipeline, the valve opening degree of each air supply pipeline is controlled, the air supply quantity is adjusted, wherein, the valve opening degree of each air supply pipeline is positively correlated with the length of each air supply pipeline, namely, the longer the air supply pipeline is, the larger the valve opening degree is, when the air supply pipeline is specifically implemented, the length of each air supply pipeline and the interval divided into different intervals can be realized, each interval corresponds to one and presets the opening value, after the length of each air supply pipeline falls into the corresponding interval, the control valve opens the corresponding preset opening value.
When only need switch on a blast pipe way, the air supply parameter of regulation specifically is the air supply wind speed of blast pipe way, specifically, if need switch on a blast pipe way, then according to the length adjustment air supply wind speed of the pipeline that switches on, wherein, the longer the length of the pipeline that switches on, the air supply wind speed is big more, when concrete implementation, can with the length of blast pipe way with divide into different intervals, every interval corresponds one and predetermines the wind speed value, after the length of blast pipe way falls into corresponding interval, with the wind speed regulation for the corresponding predetermined wind speed value, specifically, can adjust the wind speed through adjusting fan rotational speed. Through the scheme, when one or more than two air supply pipelines are communicated, air supply parameters are adjusted according to the length of the air supply pipelines, and uniform air supply is realized.
Example 3
The present embodiment provides another air supply control method, and the air supply control method of the present embodiment is applied to an air conditioner having a plurality of air supply ducts controlled by air valves, which supply air to different indoor space regions. The air conditioner comprises an inner unit, an outer unit, a control device, a storage device, an air valve device and the like.
Fig. 3 is a flowchart of an air supply control method according to another embodiment of the present invention, as shown in fig. 3, the method including:
and S1, starting the cooling mode for a first preset time.
During the concrete implementation, when inputing air conditioner mounted position detection instruction, the air conditioner opens, can all open each blast gate of air conditioner, and the aperture is opened to the biggest, opens the refrigeration mode for a period of time, for example 5min, and the purpose of this step is in order to let air conditioner entire system, including air conditioner internal unit pipeline and blast pipe line temperature reduction, all produce the difference in temperature with every indoor space region.
And S2, turning off the air supply of the air conditioner and continuing for a second preset time.
After the cooling mode is started for a period of time, the air supply of the air conditioner is closed, all air valves are closed, the cooling mode of the air conditioner is closed after a period of time is continued, the temperature of an air conditioner internal unit pipeline and an air supply pipeline is reduced, a temperature difference is generated between the temperature of each indoor space region and the temperature of each air supply pipeline, and then the air conditioner is stopped to run for a period of time, such as 1 min. The purpose of this step is to keep the room temperature in equilibrium in order to return the temperature near the tuyere in each room space to room temperature.
And S3, starting a fan reverse rotation mode.
The hot air in the room is guided to the pipeline of the air conditioner indoor unit through the air supply pipeline by reversing the motor.
And S4, sequentially and independently opening each air supply pipeline, detecting the temperature change of the pipe temperature sensing bulb, and obtaining the temperature change time required for the space where the pipeline of the air conditioner indoor unit is communicated with the currently communicated pipeline to reach the same temperature.
The temperature sensing bags are arranged in the pipelines of the air conditioner indoor unit, timing is started after a valve of one air supply pipeline is opened, temperature change of the pipe temperature sensing bags is detected, when the numerical value of the pipe temperature sensing bags is equal to the temperature value of the temperature controller in the indoor space region communicated with the opened air supply pipeline, timing is stopped, time from the opening of the valve to the target temperature is obtained, and the target temperature is the temperature value in the indoor space region communicated with the opened air supply pipeline. In order to avoid inaccurate detection results caused by the fact that the temperature of the last indoor space area is detected when a certain air supply pipeline is opened and the temperatures of the two indoor space areas are the same or close to each other, after the temperature change time of one air supply pipeline is detected each time, the refrigeration mode is started for a period of time, the pipeline of the indoor unit of the air conditioner returns to the initial temperature when the last detection is started, and in the process of detection, the last opened valve is closed, and only the valve on the detected air supply pipeline is opened alone.
And S5, judging whether the temperature changing time of all the air supply pipelines is obtained, if so, executing the step S6, and if not, repeatedly executing the step S4 until the temperature changing time of all the air supply pipelines is obtained.
And S6, determining the length of the air supply pipeline according to the temperature change time of each air supply pipeline.
The length of the air supply pipeline is the distance that air flows from an air inlet of an indoor space to a temperature sensing bulb of an indoor machine pipeline, if the air speed is constant, the time that the indoor air flows from the indoor to the position of the temperature sensing bulb is in direct proportion to the length of the air supply pipeline, therefore, the length of the air supply pipeline can be reflected by determining the time that the indoor air flows from the indoor to the position of the temperature sensing bulb, the air speed needs to be controlled to be low when the time that the indoor air flows from the indoor to the position of the temperature sensing bulb is detected, and the air speed needs to be kept unchanged when different air supply pipelines are opened, so that the temperature change time, namely the time that the indoor air flows from the indoor to the position of the temperature sensing bulb, is detected, and the length or the relative length of each air supply pipeline, namely the length ratio between each air supply pipeline, is calculated according to the temperature change time and the air speed.
S7, judging that several air supply pipelines need to be opened, if at least two air supply pipelines need to be opened, executing step S8, and if 1 air supply pipeline needs to be opened, executing step S9.
And S8, determining the opening degree of the valve on each air supply pipeline according to the length or the relative length of each air supply pipeline so as to realize air supply amount control.
Specifically, for a longer air supply pipeline, the opening degree of a valve of the air supply pipeline is increased, and the air supply quantity of an indoor space region communicated with the pipeline is increased; for a shorter air supply pipeline, the opening degree of a valve of the air supply pipeline is reduced, the air supply quantity of an indoor space region communicated with the pipeline is reduced, and the aim of balanced air supply is fulfilled. When the length difference between one air supply pipeline and other air supply pipelines is too large, so that the valve opening degree on the pipelines reaches the maximum, the valve opening degrees of the other air supply pipelines can be reduced, the pipelines with longer wind power concentration are ensured, the air quantity balance in the whole area is ensured, and the air speed is increased if the requirement of a user cannot be met.
And S9, determining the wind speed according to the length of the opened wind supply pipeline.
The embodiment is directed to a method for controlling air supply amount when at least two air supply pipelines are simultaneously opened, when only one air supply pipeline needs to be opened, if a pipeline with a shorter length is opened, a smaller air speed can be kept, and if a pipeline with a longer length is opened, the air speed needs to be increased.
According to the air supply control method, the actual length or the relative length of the air supply pipeline is determined by obtaining the temperature change time required for the space communicated by the air conditioner indoor unit pipeline and the currently communicated pipeline to reach the same temperature, the valve opening degree of the air supply pipeline is controlled according to the actual length or the relative length of the air supply pipeline, the air speed is further controlled, when spaces with different lengths need to be refrigerated or heated, the valve opening degree of the air supply pipeline with the longer length is controlled to be larger, the valve opening degree of the air supply pipeline with the shorter length is controlled to be smaller, and uniform air supply is achieved. When only one space needs to be cooled or heated, if a pipeline with a longer length is opened, the wind speed is increased compared with the case of opening a short pipeline, the temperature value suitable for a user can be reached in the space as soon as possible, and the comfort of the user is improved.
