FIG. 1 is a flow diagram illustrating a method for pipeline mapping for a multi-split pipeline according to an exemplary embodiment.
As shown in fig. 1, the present invention provides a method for pipeline mapping of a multi-split air conditioner, comprising:
and S101, sending a control signal for enabling the refrigerant pipeline to generate continuous flow on a first signal line of the multi-split air conditioner.
In this embodiment, the multi-split air conditioner is a plurality of on-line indoor units, and signal lines of the indoor units are sorted and marked. Because each indoor unit corresponds to one signal wire, the signal wires of a plurality of indoor units are gathered together, and therefore the indoor units can be sequenced. The control signals are sequentially transmitted in the signal lines. Illustratively, a signal line of the air-conditioning indoor unit is connected to a terminal strip of the host, and control signals are sent in the signal line from left to right and from top to bottom according to the position of the terminal strip.
The signal lines are used for sending signals to the indoor units, so that the flow rate of the corresponding refrigerant pipelines can be changed. The main body of the signal transmission may be a controller, and the controller is provided in the outdoor unit. For example, in a plurality of on-line air conditioning indoor units and one air conditioning outdoor unit, a signal is sent to the air conditioning indoor unit by a controller of the air conditioning outdoor unit, and in response to the signal, an electronic expansion valve of a refrigerant pipe of the air conditioning indoor unit is opened, and a refrigerant passes through the refrigerant pipe, thereby generating a flow rate.
And S102, detecting the flow rate condition of each refrigerant pipeline.
In this embodiment, the flow rate of the refrigerant pipeline is detected by the flow rate detection device. The flow rate detecting device may be a flow rate sensor disposed on the refrigerant pipeline to detect a change in flow rate. Specifically, on the refrigerant conveying pipeline, a flow sensor is arranged at a position close to the electronic expansion valve so as to detect the flow change in time. Specifically, the flow rate in the refrigerant pipeline may be a variation value of the flow rate, for example, two time points are set, and a difference value of the flow rates in the refrigerant pipeline from one time point to another time point is measured; or the trend of the flow rate between two time points, for example, measuring the value of the flow rate changing with time and drawing a corresponding straight line or curve; the flow rate may be an instantaneous value, for example, a preset time is set, and the current flow rate value is measured after the preset time is reached.
And S103, marking the refrigerant pipeline of the indoor unit generating the continuous flow.
In this embodiment, when a signal is transmitted to the indoor unit through the signal line, a flow rate is generated in the refrigerant pipe, and the refrigerant pipe is marked.
S104, establishing a corresponding relation between the marked refrigerant pipeline and the first signal line.
According to the sequence of the marks of the signal lines, the marks of the refrigerant pipelines are corresponding in sequence, and then the corresponding relation between each refrigerant pipeline and the signal line can be determined.
In an alternative embodiment, the duration of the control signal for generating the continuous flow rate in the refrigerant pipeline reaches the preset time.
In an alternative embodiment, the predetermined time is a variable or fixed value.
In the present embodiment, the preset time may be a fixed value, for example, 0.5 minute, 1 minute, 2 minutes, or the like, and the detection time of the N signal lines is N × 0.5, N × 1, N × 2, or the like; the detection time may be changed when the preset time can be shortened or lengthened according to the flow value measured by the previous refrigerant line.
In an alternative embodiment, the predetermined time is:
Ti+1=Ti×(1-α);
wherein, Ti+1For a preset time of the (i + 1) th signal line, TiThe preset time of the ith signal line is α, i is 1, N, and N is the number of the signal lines, wherein the preset time is an adjusting coefficient related to the flow condition of the refrigerant pipeline.
After the preset time of the previous signal line is determined, the preset time of the next signal line is changed based on the flow of the previous refrigerant pipeline. Therefore, the preset time of the next refrigerant pipeline can be adjusted according to the flow detection condition of the previous refrigerant pipeline, and the time for determining the corresponding relation is further shortened. Illustratively, when the flow of a previous refrigerant pipeline can be detected within a preset time, the preset time of a next signal line is shortened, and if the flow of the previous refrigerant pipeline cannot be detected within the preset time, the preset time of the next signal line is prolonged.
In an alternative embodiment, T1The value range of (1) to (2) minutes. Thus, the flow rate in the refrigerant pipeline can be detected.
In an alternative embodiment, α is greater than 0 when the flow rate of the refrigerant line can be detected, and α is less than 0 when the flow rate of the refrigerant line cannot be detected.
When the flow of the previous refrigerant pipeline can be detected, α is larger than 0, the preset time of the next refrigerant pipeline is shortened, and when the flow of the previous refrigerant pipeline cannot be detected, α is smaller than 0, the preset time of the next refrigerant pipeline is prolonged.
Specifically, the value of α is 0.2-0.3 when the flow rate of the refrigerant pipeline can be detected, and the value of α is-0.3-0.2 when the flow rate of the refrigerant pipeline can not be detected.
FIG. 2 is a schematic diagram illustrating an arrangement for pipeline mapping for multiple inline units, according to an exemplary embodiment.
As shown in fig. 2, an apparatus 300 for pipeline mapping of a multi-split air conditioner includes:
a transmitting unit 310, configured to transmit a control signal for enabling a refrigerant pipeline to generate a continuous flow rate on a first signal line of a multi-split air conditioner;

a marking unit 330 for marking the refrigerant pipe of the indoor unit generating the continuous flow rate;
the corresponding unit 340 establishes a corresponding relationship between the marked refrigerant pipeline and the first signal line.
In one embodiment of the invention, the preset time is a variable value or a fixed value.
Further, the preset time is changed according to the flow condition of the refrigerant pipeline.
In one embodiment of the present invention, the preset time is:
Ti+1=Ti×(1-α);
wherein, Ti+1For a preset time of the (i + 1) th signal line, TiThe preset time of the ith signal line is α, i is 1, N, and N is the number of the signal lines, wherein the preset time is an adjusting coefficient related to the flow condition of the refrigerant pipeline.
Further, T1The value range of (1) to (2) minutes.
In an embodiment of the present invention, α is greater than 0 when the flow rate of the refrigerant line can be detected, and α is less than 0 when the flow rate of the refrigerant line cannot be detected.
Specifically, the value of α is 0.2-0.3 when the flow rate of the refrigerant pipeline can be detected, and the value of α is-0.3-0.2 when the flow rate of the refrigerant pipeline can not be detected.
The device for the multi-split air conditioner pipeline correspondence transmits signals through the signal lines to enable the refrigerant pipelines to generate flow, and the signal lines can be in one-to-one correspondence with the refrigerant pipelines through the judgment of the refrigerant pipelines responding to the signals,
the invention also provides an air conditioner which comprises any one of the control devices.
Optionally, the air conditioner includes a plurality of indoor units, and further includes the above apparatus 300, where the apparatus 300 is disposed in the outdoor unit, and the air conditioner determines a one-to-one correspondence relationship between refrigerant pipelines and signal lines of the plurality of indoor units through the apparatus 300, thereby saving time spent in corresponding manpower, and avoiding problems caused by non-correspondence between refrigerant pipelines and signal lines.
