To better understand the split mode of the air conditioner, the split mode of the air conditioner will be described first with reference to fig. 1 and 2.
According to an embodiment of the present invention, referring to fig. 1 and 2, a variable flow diversion device is provided in an outdoor heat exchanger of an air conditioner, the variable flow diversion device including: the reversing valve 1, the first diversion pipeline 2, the second diversion pipeline 3 and at least two heat exchange pipelines 4. Wherein the first shunt pipeline 2 is connected with the second shunt pipeline 3 through at least two heat exchange pipelines 4; the first shunt pipeline 2 and the second shunt pipeline 3 are respectively provided with a main pipeline and a plurality of branch pipelines, and one-way valves 5 can be arranged in part of the branch pipelines according to the requirements.

The first communication port 101 is connected to the refrigerant inlet, and the third communication port 103 is connected to the refrigerant outlet.
The air conditioner has a variable split state and a fixed split state through the variable split device. In the case of a variable split state, the split state is adjusted in the heat exchanger of the air conditioner; in the case of the fixed split state, the split state of the refrigerant in the 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 in a multi-path split mode. In the mode of single-way diversion, 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 mode and the multiple split mode, and in the fixed split state, the air conditioner is fixed to be operated in the single split mode or the multiple split mode.
In the multi-way flow dividing mode, the reversing valve 1 is in a first station, the first communication port 101 is communicated with the second communication port 102, and the third communication port 103 is communicated with the fourth communication port 104. At this time, the second communication port 102 communicates with the first shunt line 2, and the fourth communication port 104 communicates with the second shunt line 3.

At this time, the second communication port 102 communicates with the first shunt line 2, and the fourth communication port 104 communicates with the second shunt line 3. The refrigerant of refrigerant inlet gets into by second reposition of redundant personnel pipeline 3, owing to set up check valve 5 in the partial pipeline in the first reposition of redundant personnel pipeline 2, blocks the refrigerant circulation of this pipeline through check valve 5, and the refrigerant can only exchange heat and discharge in partial heat exchange pipeline 4, reducible heat exchange pipeline this moment.
In a specific example, two heat exchange lines 4 are taken as an example, a first heat exchange line and a second heat exchange line, respectively. The first diversion pipeline 2 and the second diversion pipeline 3 are respectively provided with a main pipeline and two branch pipelines, and a check valve 5 is arranged in one branch pipeline in the first diversion pipeline 2.
In the multiple-way diversion mode, the reversing valve 1 is in the first station, the first communication port 101 is communicated with the second communication port 102, and the third communication port 103 is communicated with the fourth communication port 104. At this time, the second communication port 102 communicates with the first shunt line 2, and the fourth communication port 104 communicates with the second shunt line 3. The refrigerant of the refrigerant inlet enters through the first diversion pipeline 2, is diverted in the branch pipeline of the first diversion pipeline 2, respectively enters into the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with air, enters into the main pipeline of the refrigerant through the branch pipeline of the second diversion pipeline 3, finally passes through the fourth communication port 104 and the third communication port 103, and is discharged through the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
In the single-way split-flow mode, the reversing valve 1 is in the second station, the first communication port 101 is communicated with the fourth communication port 104, and the third communication port 103 is communicated with the second communication port 102. At this time, the second communication port 102 communicates with the first shunt line 2, and the fourth communication port 104 communicates with the second shunt line 3. The refrigerant of refrigerant entry is got into by second reposition of redundant personnel pipeline 3, owing to set up check valve 5 in the branch pipe way in the first reposition of redundant personnel pipeline 2, under its separation effect, the refrigerant only can be in first heat transfer pipeline heat transfer discharge, only carries out the heat transfer through a heat transfer pipeline at this moment.
The following describes a split control method and system for the power failure compensation function of an air conditioner and the air conditioner with reference to fig. 3 to 6. The air conditioner can be a wall-mounted air conditioner, a vertical cabinet type air conditioner, a window type air conditioner and the like.
According to an embodiment of the present invention, referring to fig. 3, the method for controlling the split flow of the power outage compensation function of the air conditioner provided by the present invention mainly includes:
S100, acquiring a first environment temperature when the air conditioner is powered off.
When the air conditioner is started to operate for a period of time and then is suddenly powered off, the current ambient temperature can be detected and recorded through the first temperature sensor.
S200, acquiring a second environment temperature of the air conditioner when the air conditioner is powered on.
The air conditioner is powered off for a period of time and then is powered on, and at this time, the current ambient temperature can be detected through the second temperature sensor.
S300, controlling the air conditioner to operate to a target diversion mode according to the temperature difference value of the first environment temperature and the second environment temperature.
According to the invention, a correct mode of shunting is provided according to the temperature difference caused by the change of the outdoor environment after power failure and power on, and the best shunting distribution is realized, so that the operation effect of the air conditioner is controlled more quickly. The target shunting mode may include a single-path shunting mode or a multi-path shunting mode or a combined shunting mode in which the single-path shunting mode and the multi-path shunting mode are switched at a certain periodic frequency.
According to the split control method for the air conditioner power failure compensation function, which is provided by the embodiment of the invention, the air conditioner is controlled to operate to the target split mode according to the first ambient temperature and the second ambient temperature when the air conditioner is powered off by acquiring the first ambient temperature and the second ambient temperature when the air conditioner is powered on, so that the memory function of the air conditioner split control is realized, the air conditioner can rapidly operate to the correct target split mode when the air conditioner is powered on, the operation effect of the air conditioner is ensured, and the use experience of a user is improved.
According to one embodiment of the present invention, the step of controlling the air conditioner to operate in the target split mode according to the temperature difference between the first ambient temperature and the second ambient temperature specifically includes:
When the temperature difference between the first environment temperature and the second environment temperature reaches a first target preset value, determining a current target diversion mode of the air conditioner according to the second environment temperature; when the temperature difference between the first ambient temperature and the second ambient temperature does not reach the first target preset value, the air conditioner is controlled to operate in a split-flow mode when power is off.
The step of determining the current target diversion mode of the air conditioner according to the second environment temperature specifically comprises the following steps:
When the second ambient temperature reaches a second target preset value, confirming that the air conditioner is in a refrigeration mode, and controlling the air conditioner to operate to a single-path diversion mode in the refrigeration mode; when the second ambient temperature reaches a third target preset value, the air conditioner is confirmed to be in a heating mode, and the air conditioner is controlled to operate to a multi-path diversion mode in the heating mode.
Because when the power failure compensation time of the air conditioner is relatively long, for example, under the condition of relatively large change of temperature difference humidity and the like in a quarter or in the morning and evening, the use experience of a user can be seriously affected. Therefore, when the air conditioner is required to be judged to be powered on, the current environment temperature of the air conditioner is suitable for a heating mode or a refrigerating mode, and then the shunting mode is determined, so that the control precision of the shunting mode is improved, and the use experience of a user is improved.
The lengths of the pipelines and the pipes through which the heat exchanger flows during refrigeration and heating are the same, but the heat exchanger, particularly the heat pump heat exchanger, has different refrigerant states at the inner side of the pipes, heat exchange temperature difference between the inner side of the pipes and the environment, refrigerant flowing speed, pressure drop, heat exchange coefficient and the like during refrigeration and heating.
When the heat exchanger is used as a condenser, the gaseous refrigerant is continuously liquefied along the flowing direction of the refrigerant, and the liquid refrigerant is more and more, so that the outlet is completely converted into the liquid refrigerant. According to the continuity principle of flow, along the flow direction of the refrigerant, the mass flow rate of the refrigerant is unchanged, the specific volume of the gaseous refrigerant is ten times of that of the liquid refrigerant, in the case of R410A refrigerant, the specific volume of saturated steam is 0.01003 m/kg at 40 ℃, the specific volume of saturated liquid is 0.00106 m/kg, the specific volume of the gaseous refrigerant is 9.5 times of that of the liquid state, that is to say, the density of the liquid state is 9.5 times of that of the gaseous state, the flow rate of the refrigerant is greatly reduced due to the greatly reduced volume of the liquefied refrigerant, and the flow rate of the refrigerant at an outlet section is low, so that the heat exchange coefficient is also low. Therefore, the optimal heat exchange effect cannot be achieved. Therefore, when the heat exchanger is used as a condenser, the supercooling degree can be improved to improve the heat exchange effect, because after the supercooling section of the condenser is enlarged, the space occupied by the liquid refrigerant is increased, the number of flow paths occupied by the saturation section and the superheating section is reduced, the total pressure drop of the condenser is reduced, the flow rate is reduced, the heat transfer coefficient is large, and the heat exchange capacity is large. Therefore, the fewer the refrigerating flow paths are, the better the refrigerating effect is, and the air conditioner is controlled to operate to a single-path diversion mode in the refrigerating mode, so that the heat exchange operation effect of the air conditioner can be effectively improved, and the use experience of a user is ensured.
When the heat exchanger is used as an evaporator, the refrigerant flows in opposite directions, the volume of the refrigerant is continuously increased as the heat exchange is carried out, the flow speed is increased in the equal sectional area, and meanwhile, the flow speed is too high, so that the flow pressure loss of the refrigerant is increased, and a part of heat exchange performance is counteracted.
When heating at low temperature, the heat exchanger is used as an evaporator, the inner side of the tube is provided with low-temperature low-pressure refrigerant, the air quantity distribution is not uniform due to structural limitation, the external heat is absorbed slowly at the position with smaller air quantity, frosting can be firstly carried out, the heat transfer between the frosted position and the external machine can be slower after frosting, the malignant circulation is carried out, the frosting can be thicker, and the heating capacity can be seriously attenuated. Therefore, when the outdoor heat exchanger is used as an evaporator, the flow paths cannot be too long, the pressure drop is larger, the temperature is lower, the frosting is more serious, the number of the flow paths is increased as much as possible, the pressure drop is reduced, and the temperature of each flow path is uniform. Therefore, the more heating pipelines are, the better the heating effect is, and the air conditioner is controlled to operate to a multi-path diversion mode in the heating mode, so that the operation effect of the air conditioner can be effectively improved, and the use experience of a user is ensured.
Specific numerical values of the target preset values of the invention are not particularly limited, and can be designed according to actual requirements.
According to one embodiment of the present invention, after the air conditioner is operated to the target split mode, the method further comprises the steps of: acquiring the air outlet temperature of the air conditioner during operation; and controlling the operation parameters of the air conditioner according to the air outlet temperature when the air conditioner operates, so that the air outlet temperature reaches the target preset temperature.
According to the invention, after the flow distribution mode is regulated, the detection control of the air outlet temperature is performed, so that the heat exchange effect of the air conditioner can be optimized, and the use experience of a user is further ensured.
