Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For the sake of understanding the present embodiment, a detailed description of a method for controlling a phase sequence of a compressor according to an embodiment of the present invention is provided below. In practical application, the air conditioner mainly comprises an outdoor unit and an indoor unit; the indoor unit mainly comprises an indoor heat exchanger, an indoor fan, a controller and the like, the outdoor unit mainly comprises an outdoor heat exchanger, a compressor and the like, the compressor can be controlled directly through the controller, the compressor can also be controlled through a special controller, and the controller is generally called in the embodiment of the invention for convenience of explanation.
Based on the above air conditioner, the embodiment of the invention provides a method for controlling a phase sequence of a compressor, wherein an execution main body is a controller, as shown in fig. 1, and the method comprises the following steps:
step S102, obtaining Run data of the running sequence of the compressor, and determining a target control sequence according to the Run data;
the target control sequence comprises a first control sequence and a second control sequence, wherein the first control sequence is used for representing the sequential phase sequence operation of the compressor, and the second control sequence is used for representing the reverse phase sequence operation of the compressor; specifically, as shown in fig. 2, when the compressor terminal and the controller terminal are connected correctly, i.e. the U-U, V-V and the W-W are connected correspondingly via the wires, at this time, the controller operates the output signals according to the sequence of U-V-W, and the compressor operates according to the sequence of U-V-W, i.e. the controller controls the operation of the compressor according to the first control sequence; when the terminals of the compressor and the terminals of the controller are connected incorrectly, as shown in fig. 3, the U-U, V-W and the W-V are connected correspondingly via wires, and at this time, the controller operates the output signals in the sequence of U-W-V, and the compressor operates in the sequence of U-W-V, i.e., the controller controls the operation of the compressor in the second control sequence.
In addition, for other cases where the compressor terminal and the controller terminal are miswired, such as where U-W, V-V and W-U are correspondingly connected via wires, the controller operates the output signals in the order U-W-V; or, under the condition that the U-V, V-U and the W-W are correspondingly connected through the lead, the controller operates the output signals according to the sequence of the U-W-V, so that when the compressor terminal and the controller terminal are in wrong wiring, the control signals corresponding to the controller all operate according to the sequence of the U-W-V, namely, the controller controls the compressor to operate according to the second control sequence, thereby realizing the correct control of the correct wiring and the incorrect wiring of the compressor terminal through the first control sequence and the second control sequence, avoiding the abnormal operation and even damage of the compressor, and prolonging the service life of the compressor.
In practical application, in order to facilitate distinguishing between two control sequences, running sequence Run data of the compressor is also set, where Run data may also be called EE data, and mainly includes: a first set value and a second set value; preferably, the first set point is 0 and the second set point is 1. The process of determining the target control sequence according to Run data is as follows: if the Run data is the first set value, the target control sequence is the first control sequence; or if the Run data is the second set value, the target control order is the second control order. Namely, when run=0, it indicates that the connection between the compressor and the controller is correct, at this time, the controller controls the compressor to operate according to the forward phase sequence of U-V-W, and when run=1, it indicates that the connection between the compressor and the controller is incorrect, at this time, the controller controls the compressor to operate according to the reverse phase sequence of U-W-V, so that the connection condition of the compressor can be rapidly distinguished through Run data, and the operation according to the corresponding control sequence is ensured, and the reliable operation of the compressor is ensured.
Step S104, controlling the compressor to run according to the target control sequence until the running time reaches the preset time;
after the target control sequence is determined, the controller controls the compressor to Run according to the target control sequence, and as Run data defaults to 0 when the compressor runs for the first time, namely the default wiring is correct, but the situation of wiring error possibly exists; in the subsequent application of the compressor, the power supply system may adjust the network, so that the control phase sequence of the compressor is changed, and the like, so that after the compressor operates for a certain time according to the target control sequence, run data also need to be checked, that is, whether the target control sequence corresponding to the Run data is correct is judged according to the situation after the actual operation. In order to avoid the wrong target control sequence and damage to the compressor when running for a long time, the above-mentioned preset time period is preferably 2 minutes.
Step S106, obtaining temperature parameters; wherein the temperature parameters include: outdoor ambient temperature, discharge temperature and return temperature of the compressor;
when the operation duration reaches the preset duration, at this time, the temperature parameter acquired by the temperature acquisition device is acquired, in practical application, because the exhaust temperature is higher than the outdoor environment temperature and the return air temperature is lower than the outdoor environment temperature when the compressor is in normal operation, and when the compressor and the controller are in wrong wiring, the exhaust temperature and the return air temperature of the compressor are both higher than the outdoor environment temperature when the compressor is in reverse-phase sequential operation, therefore, the operation sequence of the compressor can be judged according to the exhaust temperature and the return air temperature of the compressor and the outdoor environment temperature, and whether the wiring sequence of the compressor is correct or not is judged.
The temperature acquisition device is preferably a temperature sensor, for example, a first temperature sensor, a second temperature sensor and a third temperature sensor are arranged, and in practical application, the first temperature sensor is arranged on a shell of the outdoor unit so as to detect the outdoor environment temperature; a second temperature sensor is arranged at the exhaust port of the compressor to detect the exhaust temperature; the third temperature sensor is arranged at the return air port of the compressor so as to detect the return air temperature, and the specific setting position can be set according to actual conditions.
Step S108, judging whether Run data is wrong or not according to the temperature parameters;
specifically, firstly judging whether the exhaust temperature is higher than the outdoor environment temperature, and if so, namely judging whether the return air temperature is lower than the outdoor environment temperature when the exhaust temperature is higher than the outdoor environment temperature; if not, namely the return air temperature is greater than or equal to the outdoor environment temperature, at the moment, the running sequence and the wiring sequence of the compressor are inconsistent, run data are wrong, and the target control sequence of the compressor needs to be adjusted so as to ensure that the compressor runs normally and reliably.
Furthermore, the method comprises the following steps: if the return air temperature is less than the outdoor environment temperature, namely, the operation sequence and the wiring sequence of the compressor are kept consistent at the moment, the phase sequence is not required to be changed, and the compressor is controlled to operate according to the target control sequence. And if the exhaust temperature is not greater than the outdoor environment temperature, indicating that the air conditioner is abnormal at the moment, and controlling the compressor to stop running by the controller; meanwhile, alarm information, fault information and the like can be generated to prompt a user to repair the air conditioner.
And step S110, if so, correcting the Run data, and controlling the compressor to Run according to the target control sequence corresponding to the corrected Run data.
Specifically, when Run data is erroneous, correction can be performed as follows: if the Run data is the first set value, modifying the Run data to the second set value; that is, when run=0, the controller controls the compressor to operate in the forward phase sequence of U-V-W, but it is determined that the compressor is not operated in the forward phase sequence according to the temperature parameter, so that Run data needs to be modified to run=1 so that the controller operates in the reverse phase sequence of U-W-V. Or if the Run data is the second set value, the Run data is modified to the first set value, that is, when run=1, the controller controls the compressor to operate in reverse phase sequence of U-W-V, but determines that the compressor does not operate in reverse phase sequence according to the temperature parameter, so the Run data needs to be modified to run=0, so that the controller operates in forward phase sequence of U-V-W.
And for the modified Run data, a new target control sequence can be determined, so that the compressor is controlled to Run according to the new target control sequence, namely, the control sequence of the compressor is automatically adjusted, the problem of reverse phase running of the compressor caused by different running sequences and wiring sequences is relieved, and the reliable running of the compressor is ensured.
According to the phase sequence control method of the compressor, whether the wiring of the compressor terminal is wrong can be automatically judged according to the temperature parameters, and the control sequence of the compressor terminal is automatically adjusted by correcting Run data under the condition that the wiring of the compressor terminal is wrong, so that manual disassembly and rewiring are relieved, reliable operation of the compressor is guaranteed, normal operation of an air conditioner is further guaranteed, user experience is improved, and the phase sequence control method of the compressor has good practical value.
For ease of understanding, this is illustrated herein. As shown in fig. 4, the method comprises the following steps:
step S402, reading Run data; namely, the controller directly acquires running sequence Run data of the compressor;
step S404, judging run=0; namely, judging whether Run data is the first set value 0, if so, executing steps S406-S408, otherwise, executing steps S410-S412;
step S406, t starts timing; namely, starting to time the operation of the compressor;
step S408, working according to the sequence of U-V-W-U … …; namely, when Run data is a first set value, the target control sequence is a first control sequence of U-V-W;
step S410, t starts timing; namely, starting to time the operation of the compressor;
step S412, working according to the sequence of U-W-V-U … …; namely, when the Run data is a second set value, the target control sequence is a second control sequence of U-W-V;
step S414, detecting t;
step S416, judging that t is more than or equal to 2min; namely, judging whether the running time of the compressor running according to the target control sequence reaches the preset time, if so, executing the step S418, and if not, returning to the step S414 to continuously control the compressor to run according to the target control sequence;
step S418, acquiring Tr; namely, acquiring the outdoor environment temperature Tr of the compressor;
step S420, obtaining Tpi, namely obtaining the exhaust temperature Tpi of the compressor;
step S422, obtaining Tui, namely obtaining the return air temperature Tui of the compressor;
the steps S418 to S422 may be performed simultaneously, or may be performed sequentially, and may be specifically performed according to actual situations.
Step S424, judging that Tpi is larger than Tr, namely judging whether the exhaust temperature Tpi is larger than the outdoor environment temperature Tr, if not, executing step S426, and if so, executing step S428;
step S426, controlling the compressor to stop running when the air conditioner is abnormal; and, can also produce alarm information and trouble information, in order to prompt users to repair the air conditioner;
step S428, judging Tui is smaller than Tr, namely when the exhaust temperature Tpi is larger than the outdoor environment temperature Tr, judging whether the return air temperature Tui is smaller than the outdoor environment temperature Tr, if so, executing step S430, and if not, executing step S432;
step S430, controlling the compressor to continue to run; when the return air temperature is lower than the outdoor environment temperature, the operation sequence and the wiring sequence of the compressor are kept consistent, the phase sequence is not required to be changed, and the compressor is controlled to operate according to the target control sequence;
step S432, reading Run data; namely, the Run data is wrong at the moment and needs to be corrected, so that the Run data corresponding to the current target control sequence is read again;
step S434, judging run=0, if yes, executing step S436, if no, executing step S438;
step S436, run writes in 1; that is, when run=0, the controller controls the compressor to operate in the forward phase sequence of U-V-W, but determines that the compressor is not operating in the forward phase sequence according to the temperature parameter, so Run data is required to be modified to run=1, so that the controller operates in the reverse phase sequence of U-W-V, and returns to step S402 to be repeatedly executed in the subsequent operation;
step S438; run writes 0; that is, run=1, the controller controls the compressor to operate in reverse phase order of U-W-V, but determines that the compressor is not operated in reverse phase order according to the temperature parameter, so Run data is modified to run=0 so that the controller operates in forward phase order of U-V-W, and returns to step S402 to be repeatedly performed in the subsequent operation.
In summary, the phase sequence control method of the compressor provided by the embodiment of the invention can automatically judge the wiring sequence of the compressor according to the temperature parameter, and automatically adjust the three-phase working sequence of the compressor when the wiring is wrong, so that the compressor operates according to the correct control sequence, thereby solving the problem of reverse phase of the compressor, simultaneously, the wiring sequence is not needed to be considered when the wiring is carried out, the professional difficulty and the workload of wiring (operating) staff are reduced, the practical value is better, and the popularization and the implementation in practical use are facilitated.
