The invention provides a control method for air conditioner shunt, wherein the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like.
As shown in fig. 1, the indoor heat exchanger of the air conditioner is provided with a variable flow dividing device, and the variable flow dividing device includes: the system comprises a reversing valve 3, a first shunt pipeline 1, a second shunt pipeline 2 and at least two heat exchange pipelines 4. The first tapping line 1 is connected to the second tapping line 2 via at least two heat exchange lines 4. The first branch pipeline 1 and the second branch pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and a one-way valve 10 can be arranged in the middle branch pipeline according to requirements.
The selector valve 3 is a two-position four-way selector valve, and has a first communication port 31, a second communication port 32, a third communication port 33, and a fourth communication port 34, and the selector valve 3 has a first state and a second state. The first communication port 31 is connected to the refrigerant inlet, and the third communication port 33 is connected to the refrigerant outlet.
The air conditioner has a variable split state and a fixed split state. Under the condition of variable flow distribution state, the flow distribution state of the refrigerant in the indoor heat exchanger of the air conditioner is adjusted in real time; under the condition of fixed flow distribution state, the flow distribution state of the refrigerant in the indoor heat exchanger of the air conditioner is fixed.
The shunting state is divided into single-path shunting and multi-path shunting, and under the condition of multi-path shunting, refrigerant in the indoor heat exchanger of the air conditioner is subjected to multi-path shunting to work. Under the condition of single-path flow division, a refrigerant in an indoor heat exchanger of the air conditioner works in a single path. That is, the air conditioner switches between the one-way split and the multi-way split in the variable split state, and the air conditioner operates in the fixed-position one-way split or multi-way split in the fixed split state.
In the multi-path flow distribution, the selector valve 3 is in the first state, the first communication port 31 communicates with the second communication port 32, and the third communication port 33 communicates with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch flow line 1, and the fourth communication port 34 communicates with the second branch flow line 2. The refrigerant of the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipelines of the first shunting pipeline 1, respectively enters each heat exchange pipeline 4 to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 by the branch pipelines, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the heat exchange of a plurality of pipelines is realized.
When the one-way flow is branched, the selector valve 3 is in the second state, the first communication port 31 communicates with the fourth communication port 34, and the third communication port 33 communicates with the second communication port 32. At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valves 10 are arranged in part of pipelines in the first shunting pipeline 1, and under the limitation of the check valves, the refrigerant can only be subjected to heat exchange and discharged from part of the heat exchange pipelines 4, and at the moment, the heat exchange pipelines can be reduced.
In this embodiment, taking the two heat exchange pipelines 4 as an example, the two heat exchange pipelines are respectively a first heat exchange pipeline and a second heat exchange pipeline. First reposition of redundant personnel pipeline 1 and second reposition of redundant personnel pipeline 2 all are equipped with a trunk line and two spinal branchs way. A one-way valve 10 is arranged in one branch pipeline of the first shunt pipeline 1. It is assumed that the non-return valve 10 is arranged in only one of the conduits of the first tapping line 1
In the multi-path flow distribution, the selector valve 3 is in the first state, the first communication port 31 communicates with the second communication port 32, and the third communication port 33 communicates with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant at the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipeline of the first shunting pipeline 1, respectively enters the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 from the branch pipeline, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
When the one-way flow is branched, the selector valve 3 is in the second state, the first communication port 31 communicates with the fourth communication port 34, and the third communication port 33 communicates with the second communication port 32. At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valve 10 is arranged in the branch pipeline in the first shunting pipeline 1, the refrigerant can only exchange heat in the first heat exchange pipeline 4 and be discharged under the limitation of the check valve, and at the moment, the heat exchange is carried out only through one heat exchange pipeline 4.
As shown in fig. 2, the control method of air conditioner split flow includes the following steps:
step S110: and acquiring the ambient temperature of the air conditioner.
After the air conditioner is started, a user can control the air conditioner through the electronic equipment or the remote controller. In the process, if the air conditioner receives an instruction of the shunting function, the air conditioner detects the ambient temperature of the current scene by using the sensor.
Step S120: and adjusting the running state of the air conditioner according to the running mode and the ambient temperature of the air conditioner.
And after the ambient temperature is obtained, adjusting the running state of the air conditioner according to the running mode of the air conditioner. The air conditioner has a variable split state and a fixed split state. Under the condition of variable shunting state, the refrigerant in the indoor heat exchanger of the air conditioner adjusts the shunting state in real time. Under the condition of fixed flow distribution state, the flow distribution state of the refrigerant in the indoor heat exchanger of the air conditioner is fixed.
And if the air conditioner is in a refrigeration mode, adjusting the air conditioner to switch between a variable shunting state and a fixed shunting state according to the refrigeration temperature range of the ambient temperature.
For example, when the outdoor temperature is high and the ambient temperature is greater than or equal to 48 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and heat exchange is easily affected at the temperature, the air conditioner is adjusted to be in a variable shunting state, and the four-way valve is used for adjusting in real time to enable the air conditioner to perform single-path shunting or multi-path shunting. At the moment, according to actual conditions, the air conditioner can exchange heat through partial heat exchange pipelines or all heat exchange pipelines so as to ensure the heat exchange effect.
When outdoor temperature is normal, when ambient temperature is less than or equal to 35 ℃, the difference in temperature of refrigerant temperature and ambient temperature is normal, and no matter this moment is single shunting or multichannel reposition of redundant personnel all can guarantee the heat transfer effect, then the adjustment air conditioner is fixed reposition of redundant personnel state. The air conditioner is fixed to perform single-path shunting or multi-path shunting heat exchange.
And if the air conditioner is in a heating mode, adjusting the air conditioner to switch between a variable shunting state and a fixed shunting state according to the heating temperature range of the environment temperature.
For example, when the outdoor temperature is low and the ambient temperature is less than or equal to-7 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and heat exchange is easily affected at the temperature, the air conditioner is adjusted to be in a variable shunting state, and the four-way valve is used for adjusting in real time to enable the air conditioner to perform single-path shunting or multi-path shunting. At the moment, according to actual conditions, the air conditioner can exchange heat through partial heat exchange pipelines or all heat exchange pipelines so as to ensure the heat exchange effect.
When outdoor temperature is normal, when ambient temperature is more than or equal to 6 ℃, no matter this moment be single shunting or multichannel reposition of redundant personnel all can guarantee the heat transfer effect, then adjust the air conditioner for fixed reposition of redundant personnel state. The air conditioner does not need to change the state, and the air conditioner is fixed to carry out single-path shunting or multi-path shunting heat exchange.
The air conditioner shunting control method provided by the invention firstly adjusts the running state of the air conditioner by acquiring the ambient temperature of the air conditioner according to the running mode and the ambient temperature of the air conditioner, so that the air conditioner is switched between a variable shunting state and a fixed shunting state, the shunting state of a refrigerant in an indoor heat exchanger is changed, the variable shunting state is selected for refrigerating in the environment with higher temperature, the variable shunting state can be selected for heating in the environment with lower temperature of the air conditioner, and the fixed shunting state is selected in the environment with normal temperature, so that the air conditioner can select the optimal running state in different ambient temperatures, and the performance of the air conditioner is improved.
As shown in table 1, the refrigeration temperature ranges include: the temperature of the first refrigerating interval, the second refrigerating interval and the third refrigerating interval is set from low to high in sequence. As shown in fig. 3, if the air conditioner is in the cooling mode, the step of adjusting the air conditioner to switch between the variable split state and the fixed split state according to the cooling temperature range of the ambient temperature includes:
step S310: and if the ambient temperature is in the first refrigeration interval, adjusting the air conditioner to be in a fixed shunting state.
For example, when the ambient temperature corresponds to the level T1 and is less than or equal to 35 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, both the single-path flow distribution and the multi-path flow distribution can achieve the heat exchange effect, and the air conditioner is adjusted to be in a fixed flow distribution state. The air conditioner does not need to change the state, and the air conditioner is fixed to carry out single-path shunting or multi-path shunting heat exchange.
Step S320: and if the ambient temperature is in the second refrigeration interval, adjusting the air conditioner to be in a fixed shunting state or a variable shunting state.
For example, when the ambient temperature corresponds to the level T2 and is between 35 ℃ and 48 ℃, the operating state of the air conditioner is adjusted by determining whether the variable split state is required according to the user's requirement.
Step S330: and if the ambient temperature is in the third refrigerating interval, adjusting the air conditioner to be in a variable shunting state.
For example, when the ambient temperature corresponds to the level T3 and is greater than or equal to 48 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and heat exchange is easily affected at this temperature, the air conditioner is adjusted to be in a variable flow distribution state, and the four-way valve is used for real-time adjustment to enable the air conditioner to perform single-path flow distribution or multi-path flow distribution. At this time, according to actual conditions, the air conditioner can exchange heat through part of or all of the heat exchange pipelines. The multi-path flow division is selected during air-conditioning refrigeration, so that the capacity of the air-conditioning refrigeration can be further exerted, and therefore, the multi-path flow division is usually selected during the air-conditioning refrigeration to improve the effect of the air-conditioning.
TABLE 1
As shown in table 1, the heating temperature range includes: the temperature of the first heating section, the second heating section and the third heating section is set from high to low in sequence. As shown in fig. 4, if the air conditioner is in the heating mode, the step of adjusting the switching of the air conditioner between the variable split state and the fixed split state according to the heating temperature range of the ambient temperature includes:
step S410: and if the ambient temperature is in the first heating interval, adjusting the air conditioner to be in a fixed shunting state.
For example, the ambient temperature corresponds to a grade T1, when the ambient temperature is greater than or equal to 6 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, both the single-path flow distribution and the multi-path flow distribution can realize the heat exchange effect, and the air conditioner is adjusted to be in a fixed flow distribution state. The air conditioner does not need to change the state, and the air conditioner is fixed to carry out single-path shunting or multi-path shunting heat exchange.
Step S420: and if the ambient temperature is in the second heating interval, adjusting the air conditioner to be in a fixed shunting state or a variable shunting state.
For example, when the ambient temperature corresponds to the level T2 and is between-7 ℃ and 6 ℃, the operating state of the air conditioner is adjusted by determining whether the variable split state is required according to the user's requirement.
Step S430: and if the ambient temperature is in the third heating interval, adjusting the air conditioner to be in a variable shunting state.
For example, when the ambient temperature corresponds to the level T3 and is less than or equal to-7 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and heat exchange is easily affected at this temperature, the air conditioner is adjusted to a variable flow distribution state, and the four-way valve is used for real-time adjustment to enable the air conditioner to perform single-path flow distribution or multi-path flow distribution. At this time, according to actual conditions, the air conditioner can exchange heat through part of or all of the heat exchange pipelines. When the air conditioner heats, the capacity of the air conditioner can be further exerted by selecting the single-way shunt, so that the supercooling degree of the air conditioner is improved by selecting the single-way shunt usually when the air conditioner heats.
Since the temperature of the intake air is different from the ambient temperature, after the air conditioner operates for a period of time, in order to ensure the working effect of the air conditioner, as shown in fig. 5, in step S120: according to the operation mode and the ambient temperature of the air conditioner, the method also comprises the following steps after the operation state of the air conditioner is adjusted:
step S130: and acquiring the air inlet temperature of the air conditioner.
After the operation state of the air conditioner is adjusted, the temperature of the inlet air is detected by using a sensor.
Step S140: and judging whether the inlet air temperature meets the requirement or not according to the running mode and the running state of the air conditioner.
If the air conditioner is in the refrigeration mode, judging whether the current running state of the air conditioner is normal or not and whether the air inlet temperature is in the correct refrigeration temperature range or not according to the refrigeration temperature range in which the air inlet temperature is located.
If the air conditioner is in the heating mode, judging whether the current running state of the air conditioner is normal or not and whether the air inlet temperature is in the correct heating temperature range or not according to the heating temperature range where the air inlet temperature is located.
Step S150: and if the inlet air temperature meets the requirement, controlling and keeping the running state of the air conditioner.
Step S160: and if the inlet air temperature does not meet the requirement, adjusting the running state and returning to the step of obtaining the inlet air temperature of the air conditioner.
For example, when the air conditioner is in a cooling mode, if the temperature of the inlet air is detected to be less than or equal to 35 ℃, the air conditioner should be in a fixed shunting state, and single-path shunting or multi-path shunting is adopted for fixation. And if the air conditioner is in the variable shunting state at the moment, adjusting the running state to be the fixed shunting state, and returning to the step of acquiring the inlet air temperature of the air conditioner. If the air conditioner is in the fixed shunting state at the moment, the running state of the air conditioner is kept.
When the air conditioner is in a refrigeration mode, if the detected inlet air temperature is greater than or equal to 48 ℃, the air conditioner should correspond to a variable shunting state, and the shunting state is adjusted in real time. If the air conditioner is in the variable flow dividing state, the running state of the air conditioner is kept. And if the air conditioner is in the fixed shunting state at the moment, adjusting the running state to be in the variable shunting state, and returning to the step of acquiring the inlet air temperature of the air conditioner.
And when the air conditioner is in a heating mode, if the temperature of the inlet air is detected to be greater than or equal to 6 ℃, the air conditioner is in a corresponding fixed shunting state, and single-path shunting or multi-path shunting is adopted for fixation. And if the air conditioner is in the variable shunting state at the moment, adjusting the running state to be the fixed shunting state, and returning to the step of acquiring the inlet air temperature of the air conditioner. If the air conditioner is in the fixed shunting state at the moment, the running state of the air conditioner is kept.
And if the ambient temperature is less than or equal to minus 7 ℃, the air conditioner should correspond to the variable shunting state and adjust the shunting state in real time. If the air conditioner is in the variable flow dividing state, the running state of the air conditioner is kept. And if the air conditioner is in the fixed shunting state at the moment, adjusting the running state to be in the variable shunting state, and returning to the step of acquiring the inlet air temperature of the air conditioner.
