The invention provides a control method for air conditioner split flow, which can be a wall-mounted air conditioner, a vertical cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like.
As shown in fig. 1 and 2, the outdoor heat exchanger of the air conditioner is provided with a variable flow dividing device including: the reversing valve 3, the first diversion pipeline 1, the second diversion pipeline 2 and at least two heat exchange pipelines 4. The first shunt line 1 is connected to the second shunt line 2 via at least two heat exchange lines 4. The first diversion pipeline 1 and the second diversion pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and one-way valves 10 can be arranged in part of the branch pipelines according to the requirement.
The reversing valve 3 is a two-position four-way reversing valve, and is provided with a first communication port 31, a second communication port 32, a third communication port 33 and a fourth communication port 34, and the reversing 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 split state, the refrigerant in the outdoor heat exchanger of the air conditioner adjusts the split state in real time; in the case of the fixed split state, the split state of the refrigerant in the outdoor heat exchanger of the air conditioner is fixed.
The split state is divided into single-path split and multi-path split, and refrigerant multi-path split in the outdoor heat exchanger of the air conditioner works under the condition of multi-path split. Under the condition of single-way split flow, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single way. That is, in the variable split state, the air conditioner is switched between the single split and the multi-split, and in the fixed split state, the air conditioner is fixed to operate in the single split or the multi-split.
When the multiple-way flow is split, the reversing valve 3 is in the first state, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first shunt line 1, and the fourth communication port 34 communicates with the second shunt line 2. The refrigerant of the refrigerant inlet enters from the first diversion pipeline 1, is diverted in branch pipelines of the first diversion pipeline 1, respectively enters into each heat exchange pipeline 4 to exchange heat with indoor air, enters into a main pipeline of the refrigerant through branch pipelines of the second diversion pipeline 2, finally passes through the fourth communication port 34 and the third communication port 33, is discharged from a refrigerant outlet, and realizes the heat exchange of a plurality of pipelines.
When the single-way split flow is carried out, the reversing valve 3 is in the second state, the first communication port 31 is communicated with the fourth communication port 34, and the third communication port 33 is communicated with the second communication port 32. At this time, the second communication port 32 communicates with the second split line 2, and the fourth communication port 34 communicates with the first split line 1. The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in part of the pipelines in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in part of the heat exchange pipeline 4 under the limitation of the one-way valve, and the heat exchange pipeline can be reduced at the moment.
In this embodiment, two heat exchange pipelines 4 are taken as an example, and are a first heat exchange pipeline and a second heat exchange pipeline respectively. The first shunt pipeline 1 and the second shunt pipeline 2 are respectively provided with a main pipeline and two branch pipelines. One branch pipe in the first diversion pipeline 1 is provided with a one-way valve 10. It is assumed that the one-way valve 10 is provided in only one of the branch lines of the first shunt line 1
When the multiple-way flow is split, the reversing valve 3 is in the first state, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first shunt line 1, and the fourth communication port 34 communicates with the second shunt line 2. The refrigerant of the refrigerant inlet enters from the first diversion pipeline 1, is diverted in the branch pipeline of the first diversion pipeline 1, respectively enters into the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with indoor air, enters into the main pipeline of the refrigerant through the branch pipeline of the second diversion pipeline 2, finally passes through the fourth communication port 34 and the third communication port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
When the single-way split flow is carried out, the reversing valve 3 is in the second state, the first communication port 31 is communicated with the fourth communication port 34, and the third communication port 33 is communicated with the second communication port 32. At this time, the second communication port 32 communicates with the second split line 2, and the fourth communication port 34 communicates with the first split line 1. The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in the branch pipeline in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in the first heat exchange pipeline 4 under the limitation of the one-way valve, and only exchanges heat through one heat exchange pipeline 4 at the moment.
As shown in fig. 3, the control method of the 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 environmental 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 environmental temperature of the air conditioner.
After the environmental temperature is obtained, the running state of the air conditioner is adjusted 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 split state, the refrigerant in the outdoor heat exchanger of the air conditioner adjusts the split state in real time. In the case of the fixed split state, the split state of the refrigerant in the outdoor heat exchanger of the air conditioner is fixed.
If the air conditioner is in the refrigeration mode, the air conditioner is adjusted to switch between a variable split state and a fixed split state according to the refrigeration temperature range where the ambient temperature is located.
For example, when the outdoor temperature is higher, the temperature difference between the refrigerant temperature and the ambient temperature is smaller when the ambient temperature is higher than or equal to 48 ℃, and the heat exchange is easily affected at the temperature, the air conditioner is adjusted to be in a variable split state, and the four-way valve is used for real-time adjustment to enable the air conditioner to perform one-way split or multi-way split. At this time, according to actual conditions, the air conditioner can exchange heat through part of heat exchange pipelines or all heat exchange pipelines, so as to ensure the heat exchange effect.
When the outdoor temperature is normal, when the ambient temperature is less than or equal to 35 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, at the moment, the heat exchange effect can be ensured no matter the refrigerant is split in a single-way or multi-way, and the air conditioner is adjusted to be in a fixed split state. The air conditioner is fixed to perform single-path split flow or multi-path split flow heat exchange.
And if the air conditioner is in the heating mode, adjusting the air conditioner to switch between a variable split state and a fixed split state according to the heating temperature range where the ambient temperature is.
For example, when the outdoor temperature is low, the temperature difference between the refrigerant temperature and the ambient temperature is small when the ambient temperature is less than or equal to-7 ℃, and the heat exchange is easy to influence at the temperature, the air conditioner is adjusted to be in a variable split state, and the four-way valve is used for real-time adjustment to enable the air conditioner to perform one-way split or multi-way split. At this time, according to actual conditions, the air conditioner can exchange heat through part of heat exchange pipelines or all heat exchange pipelines, so as to ensure the heat exchange effect.
When the outdoor temperature is normal, and the ambient temperature is higher than or equal to 6 ℃, the heat exchange effect can be ensured no matter the air conditioner is in single-path split flow or multi-path split flow, and the air conditioner is adjusted to be in a fixed split flow state. The state is not required to be changed, and the air conditioner is fixed to perform single-path split-flow or multi-path split-flow heat exchange.
According to the control method for air conditioner split flow, the running state of the air conditioner is adjusted according to the running mode and the environment temperature of the air conditioner by acquiring the environment temperature of the air conditioner, so that the air conditioner can be switched between the variable split flow state and the fixed split flow state, when the air conditioner is used for refrigerating in the environment with higher temperature, the variable split flow state is selected for refrigerating, when the air conditioner is used for heating in the environment with lower temperature, the variable split flow state is selected for heating, and when the air conditioner is used for heating in the environment with normal temperature, the fixed split flow state is selected, and therefore the air conditioner can be used for selecting the optimal running state in different environment temperatures, and the performance of the air conditioner is improved.
As shown in fig. 4, 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 in which the ambient temperature is located includes:
step S410: a first boundary temperature is obtained.
In the process of adjusting the running state, if the air conditioner is in the refrigeration mode, acquiring a first boundary temperature corresponding to the refrigeration mode, wherein the first boundary temperature is the critical temperature of the switching state.
Step S420: and if the ambient temperature is greater than or equal to the first boundary temperature, adjusting the air conditioner to be in a variable split state.
If the ambient temperature is greater than or equal to the first boundary temperature, for example, when the ambient temperature is greater than or equal to 48 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and the heat exchange is easy to influence at the temperature, the air conditioner is adjusted to be in a variable split state, and the four-way valve is utilized for real-time adjustment to enable the air conditioner to perform one-way split or multi-way split. At this time, according to actual conditions, the air conditioner can exchange heat through part of heat exchange pipelines or all of the heat exchange pipelines. When the air conditioner is used for refrigerating, the multi-way flow is selected, so that the capacity of the air conditioner can be further exerted, and when the air conditioner is used for refrigerating, the multi-way flow is generally selected to improve the effect of the air conditioner.
Step S430: and if the ambient temperature is less than the first boundary temperature, adjusting the air conditioner to be in a fixed split state.
If the ambient temperature is less than the first boundary temperature, for example, when the ambient temperature is less than 48 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, and the heat exchange effect can be realized by both single-path split flow and multi-path split flow, the fixed split flow state can be selected. The state is not required to be changed, and the air conditioner is fixed to perform single-path split-flow or multi-path split-flow heat exchange.
As shown in fig. 5, if the air conditioner is in the heating mode, the step of adjusting the air conditioner to switch between the variable split state and the fixed split state according to the heating temperature range in which the ambient temperature is located includes:
step S510: a second boundary temperature is obtained.
In the process of adjusting the running state, if the air conditioner is in the heating mode, acquiring a second boundary temperature corresponding to the heating mode, wherein the second boundary temperature is the critical temperature of the switching state.
Step S520: and if the ambient temperature is less than or equal to the second boundary temperature, adjusting the air conditioner to be in a variable split state.
If the ambient temperature is less than or equal to the second boundary temperature, for example, the ambient temperature is less than or equal to minus 7 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, the heat exchange is easy to influence at the temperature, the air conditioner is adjusted to be in a variable split state, and the four-way valve is utilized for real-time adjustment to enable the air conditioner to perform one-way split or multi-way split. At this time, according to actual conditions, the air conditioner can exchange heat through part of heat exchange pipelines or all of the heat exchange pipelines. The single-way split flow is selected when the air conditioner heats, so that the capacity of the air conditioner can be further exerted, and therefore, the single-way split flow is generally selected when the air conditioner heats so as to improve the supercooling degree of the air conditioner.
Step S530: and if the ambient temperature is greater than the second boundary temperature, adjusting the air conditioner to be in a fixed split state.
If the ambient temperature is greater than the second boundary temperature, for example, the ambient temperature is > -7 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, and the heat exchange effect can be realized by both single-path diversion and multi-path diversion, then the fixed diversion state can be selected. The state is not required to be changed, and the air conditioner is fixed to perform single-path split-flow or multi-path split-flow heat exchange.
In order to ensure the working effect when the air conditioner is in the variable split state, after the air conditioner is operated for a period of time, in step S120: according to the operation mode and the environment temperature of the air conditioner, the method further comprises the following steps of:
step S130: and controlling to increase the working frequency of the compressor in the air conditioner.
Step S140: and obtaining the exhaust temperature of the air conditioner.
After the air conditioner is in a variable split state, the air conditioner can perform single-path split or multi-path split, and in order to improve the heat exchange effect, the reversing is utilized to enable the air conditioner to exchange heat quickly, the air conditioner is changed into multi-path split from the single-path split, or the working frequency of a compressor in the air conditioner is controlled to be increased in the process that the multi-path split is changed into the single-path split, so that the exhaust temperature of the air conditioner is obtained, namely the temperature of a refrigerant flowing out of the variable split device is obtained.
Step S150: and judging whether the exhaust temperature reaches a threshold value according to the operation mode of the air conditioner.
And judging whether the exhaust temperature reaches a threshold value according to the operation mode of the air conditioner. When the air conditioner is in a refrigerating state, whether the exhaust temperature reaches a limit value in refrigerating or not is judged.
