In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1, a system architecture diagram of a general air conditioner in the related art is shown. When the heating operation is performed, the refrigerant is discharged from the exhaust port of the compressor, reaches the heat exchanger of the inner machine, and then flows to the heat exchanger of the outer machine through the electronic expansion valve of the outer machine. After passing through the external heat exchanger, the refrigerant flows back to the gas-liquid separator through the four-way valve to complete the heating cycle of the refrigerant.
When the air conditioning system is in heating operation, the external machine can frost on the heat exchanger of the external machine along with the lengthening of the operation time. With the thickening of the frost layer, the air conditioning system generally controls the external machine to defrost.
When defrosting is finished, the air conditioner is restarted and operates according to the previous mode. In this case, the air-conditioning refrigerant oil may be precipitated from the refrigerant to clog the throttle unit. This situation can lead to poor air conditioning heating and prevent oil from flowing back to the compressor, compromising system reliability.
When the air conditioner is in defrosting operation, the refrigerant runs according to the refrigerating operation direction, so that the temperature of the indoor heat exchanger is continuously reduced, and even an oil film is generated on a pipeline of the heat exchanger of the internal machine. When the external machine is restarted, the refrigerant flows through the indoor side, but the temperature of the indoor side heat exchanger is too low, the temperature difference of the refrigerant is larger, and therefore the heat exchange quantity is larger.
After the refrigerant flows out of the indoor heat exchanger, the temperature is much lower than that of normal operation, and part of lubricating oil can be separated out from the refrigerant. At this time, after the refrigerant passes through the throttling component of the external machine, the low pressure can be reduced more, and the saturation temperature of the low pressure can be even reduced to be lower than the pour point temperature of the lubricating oil (the lowest flowable temperature of the lubricating oil), so that the throttling component is blocked, and the heating effect of the air conditioner is reduced.
Aiming at the above situation, the embodiment provides an air conditioner control system, an air conditioner, a multi-split control system and a multi-split, which can at least partially solve the technical problems.
As shown in fig. 2, the present embodiment provides an air conditioner control system 20, which is applied to an air conditioner 10, wherein the air conditioner 10 includes an internal heat exchanger 15, and the internal heat exchanger 15 includes a plurality of refrigerant flow paths. The air conditioning control system 20 includes a valve arrangement and a controller.
The refrigerant flow path includes a first flow path 31, and the valve device includes a first solenoid valve 21 provided in the first flow path 31.
The controller is communicatively connected to the first solenoid valve 21.
The indoor heat exchanger 15 of the air conditioner 10 is divided into a plurality of refrigerant channels including a first channel 31, and the first channel 31 is provided with a first electromagnetic valve 21. When the air conditioner 10 is operating normally, the controller can control the first electromagnetic valve 21 to open, so that the heat exchanger 15 of the internal machine works normally, and all refrigerant flow paths including the first flow path 31 in the heat exchanger 15 of the internal machine can circulate.
When the air conditioner 10 is in the heating and defrosting operation mode, the four-way valve of the air conditioner 10 is reversed, and the flowing direction of the refrigerant is opposite to the heating direction. At this time, the controller may control the first electromagnetic valve 21 to be closed, so that the refrigerant only passes through other refrigerant channels in the inner heat exchanger 15, and the refrigerant does not perform enough heat exchange in the outer heat exchanger, and then enters part of the refrigerant channels in the inner heat exchanger 15. Since the refrigerant flowing through the inner heat exchanger 15 has a relatively small number of flow paths, the temperature of the inner heat exchanger 15 is not lowered much even if enough heat exchange is not performed on the inner heat exchanger 15. So that the frozen oil is not separated out. In order to further reduce the heat exchange amount of the external heat exchanger, the external motor can be turned off during defrosting.
When the defrosting of the air conditioner 10 is completed and the air conditioner is restarted, the first electromagnetic valve 21 can be kept in a closed state, so that the area of the heat exchanger of the internal heat exchanger 15 participating in heating is reduced, the heat dissipation capacity of the refrigerant is reduced, and the refrigerant temperature is prevented from being too low. Meanwhile, the external fan can be adjusted to be the maximum windshield for improving the heat exchange quantity of the external machine heat exchanger, so that the refrigerant absorbs more heat, and the return air pressure and the return air temperature are improved. When the start-up phase is over, the controller controls the air conditioner 10 to enter a normal heating mode and opens the first solenoid valve 21.
Optionally, as shown in fig. 3, the internal heat exchanger 15 further includes a second flow path 32 and a third flow path 33, and the valve device further includes a second solenoid valve 22 and a third solenoid valve 23.
The second solenoid valve 22 is disposed in the second flow path 32. The third solenoid valve 23 is provided in the third flow path 33.
The controller is communicatively connected to the second solenoid valve 22 and the third solenoid valve 23, respectively.
Similar to the principle of the first solenoid valve 21, a solenoid valve may be installed in each refrigerant flow path of the indoor unit heat exchanger 15, that is, the second solenoid valve 22 is installed in the second flow path 32, and the third solenoid valve 23 is installed in the third flow path 33. In this way, the air conditioner 10 can more flexibly adjust the refrigerant flow path in the inner machine heat exchanger 15 under the conditions of defrosting and re-heating starting after defrosting, and the accuracy of adjustment is improved.
Based on the same inventive concept, as shown in fig. 3, the utility model also provides an air conditioner 10, wherein the air conditioner 10 comprises an inner heat exchanger 15 and an air conditioner control system 20, and the inner heat exchanger 15 comprises a plurality of refrigerant flow paths. The air conditioning control system 20 includes a valve arrangement and a controller.
The refrigerant flow path includes a first flow path 31, the valve device includes a first solenoid valve 21, and the first solenoid valve 21 is disposed on the first flow path 31.
The controller is communicatively connected to the first solenoid valve 21.
Optionally, as shown in fig. 3, the internal heat exchanger 15 further includes a second flow path 32 and a third flow path 33, and the valve device further includes a second solenoid valve 22 and a third solenoid valve 23.
The second solenoid valve 22 is disposed in the second flow path 32. The third solenoid valve 23 is provided in the third flow path 33.
The controller is communicatively connected to the second solenoid valve 22 and the third solenoid valve 23, respectively.
Optionally, the air conditioner 10 further includes an external machine heat exchanger 13, an external machine electronic expansion valve 14, a reversing valve 12, and a compressor 11.
The outer heat exchanger 13 is disposed on a refrigerant total flow path between the inner heat exchanger 15 and the compressor 11, and the refrigerant total flow path is a refrigerant pipe in which a plurality of refrigerant flow paths flow out from the inner heat exchanger 15 and then merge.
The outer machine electronic expansion valve 14 is arranged on the refrigerant total flow path between the inner machine heat exchanger 15 and the outer machine heat exchanger 13.
The reversing valve 12 is provided between the compressor 11 and the external heat exchanger 13.
One end of the compressor 11 is connected with the external heat exchanger 13 through the reversing valve 12, and the other end of the compressor 11 is connected with the internal heat exchanger 15 through the gas-liquid separator.
When the air conditioner 10 is in heating operation, the refrigerant is discharged from the exhaust port of the compressor 11, passes through the reversing valve 12 and reaches the inner machine heat exchanger 15, exchanges heat through each refrigerant flow path in the inner machine heat exchanger 15, then merges into the main refrigerant flow path, and then flows through the outer machine electronic expansion valve 14 and then flows into the outer machine heat exchanger 13. After passing through the external heat exchanger 13, the refrigerant flows back to the gas-liquid separator through the reversing valve to complete the heating cycle of the refrigerant.
During defrosting operation, the refrigerant flows in the pipe in the cooling operation direction (i.e., the direction opposite to the heating direction).
