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, the indoor heat exchanger of the air conditioner is provided with a variable flow dividing device, which includes: 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. In the case of a variable split state, the split state is adjusted in real time by cooling in an indoor heat exchanger of the air conditioner; in the case of the fixed split state, the split state of the refrigerant in the indoor heat exchanger of the air conditioner is fixed.
The split state is divided into single-path split and multi-path split, and the cold multi-path split works in an indoor heat exchanger of the air conditioner under the condition of multi-path split. Under the condition of single-path diversion, the indoor heat exchanger of the air conditioner works in a cold single-path mode. 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. 2, 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. In the case of a variable split state, the split state is adjusted in real time by cooling in an indoor heat exchanger of the air conditioner. In the case of the fixed split state, the split state of the refrigerant in the indoor 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, so that the air conditioner is switched between the variable split flow state and the fixed split flow state, the split flow state of a refrigerant in an indoor heat exchanger is changed, 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 is enabled to select the optimal running state in different environment temperatures, and the performance of the air conditioner is improved.
As shown in table 1, the cooling temperature ranges include: the temperature is set from low to high in the first refrigeration interval, the second refrigeration interval and the third refrigeration interval 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 in which the ambient temperature is located includes:
step S310: and if the ambient temperature is in the first refrigeration interval, adjusting the air conditioner to be in a fixed split state.
For example, when the ambient temperature is lower than or equal to 35 ℃ and the temperature difference between the refrigerant temperature and the ambient temperature is normal, the heat exchange effect can be realized by single-path diversion and multi-path diversion, and the air conditioner is adjusted to be in a fixed diversion 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.
Step S320: and if the ambient temperature is in the second refrigeration interval, adjusting the air conditioner to be in a fixed split state or a variable split state.
For example, when the ambient temperature is between 35 ℃ and 48 ℃ corresponding to the level T2, it is determined whether the variable split state is needed according to the user's requirement, so as to adjust the working state of the air conditioner.
Step S330: and if the ambient temperature is in the third refrigeration interval, adjusting the air conditioner to be in a variable split state.
For example, when the ambient temperature is greater than or equal to 48 ℃ and the ambient temperature corresponds to the level T3, 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. 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.
TABLE 1
As shown in table 1, the heating temperature ranges include: the temperature is sequentially set from high to low in the first heating interval, the second heating interval and the third heating interval. As shown in fig. 4, 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 S410: and if the ambient temperature is in the first heating interval, adjusting the air conditioner to be in a fixed split state.
For example, when the ambient temperature is equal to or higher than 6 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is normal, and the heat exchange effect can be realized by single-path diversion and multi-path diversion, so that the air conditioner is adjusted to be in a fixed diversion 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.
Step S420: and if the ambient temperature is in the second heating interval, adjusting the air conditioner to be in a fixed split state or a variable split state.
For example, when the ambient temperature is between-7 ℃ and 6 ℃ corresponding to the level T2, whether the variable diversion state is needed or not is determined according to the user demand, so as to adjust the working state of the air conditioner.
Step S430: and if the ambient temperature is in the third heating interval, adjusting the air conditioner to be in a variable split state.
For example, when the ambient temperature is less than or equal to-7 ℃, the temperature difference between the refrigerant temperature and the ambient temperature is small, and the heat exchange is easy to be influenced 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 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.
Since the intake air temperature is different from the ambient temperature, after the air conditioner is operated for a period of time, as shown in fig. 5, 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 acquiring the air inlet temperature of the air conditioner.
After the running state of the air conditioner is adjusted, the sensor is used for detecting the air inlet temperature.
Step S140: and judging whether the air inlet temperature meets the requirement 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 running state of the current air conditioner is normal or not according to the refrigeration temperature range where the air inlet temperature is located, and judging whether the air inlet temperature is in the correct refrigeration temperature range or not.
If the air conditioner is in the heating mode, judging whether the current running state of the air conditioner is normal or not according to the heating temperature range where the air inlet temperature is located, and judging whether the air inlet temperature is in the correct heating temperature range or not.
Step S150: and if the air inlet temperature meets the requirement, controlling and maintaining the running state of the air conditioner.
Step S160: if the air inlet temperature does not meet the requirement, the running state is adjusted, and the step of acquiring the air inlet temperature of the air conditioner is returned.
For example, when the air conditioner is in the state of cooling mode, if the detected air inlet temperature is less than or equal to 35 ℃, the air conditioner should be in a fixed split state, and single-path split or multi-path split is adopted for fixing. And if the air conditioner is in the variable split state at this time, adjusting the running state to be a fixed split state, and returning to the step of acquiring the air inlet temperature of the air conditioner. If the air conditioner is in the fixed split state at this time, the running state of the air conditioner is maintained.
When the air conditioner is in a state of a refrigeration mode, if the inlet air temperature is detected to be more than or equal to 48 ℃, the air conditioner is supposed to correspond to a variable split state, and the split state is adjusted in real time. If the air conditioner is in the variable diversion state at this time, the running state of the air conditioner is maintained. And if the air conditioner is in the fixed split state at this time, adjusting the running state to be a variable split state, and returning to the step of acquiring the air inlet temperature of the air conditioner.
And when the air conditioner is in a heating mode, if the inlet air temperature is detected to be more than or equal to 6 ℃, the air conditioner should correspond to a fixed split state, and single-path split or multi-path split is adopted for fixation. And if the air conditioner is in the variable split state at this time, adjusting the running state to be a fixed split state, and returning to the step of acquiring the air inlet temperature of the air conditioner. If the air conditioner is in the fixed split state at this time, the running state of the air conditioner is maintained.
If the ambient temperature is less than or equal to-7 ℃, the air conditioner should correspond to a variable split state, and the split state is adjusted in real time. If the air conditioner is in the variable diversion state at this time, the running state of the air conditioner is maintained. And if the air conditioner is in the fixed split state at this time, adjusting the running state to be a variable split state, and returning to the step of acquiring the air inlet temperature of the air conditioner.
