Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to enable a constant speed air conditioner without a controller in an outdoor unit to realize detection of reverse rotation of a compressor, the embodiment of the invention provides a method for detecting reverse rotation of the compressor, and the method is applied to the constant speed air conditioner. And the outdoor unit of the air conditioner does not comprise a controller, and the indoor unit comprises a controller.
The embodiment of the present invention is described herein by taking an air conditioner as a one-by-one constant speed air conditioner, as shown in fig. 1. The air conditioner comprises an indoor unit and an outdoor unit. Wherein, indoor set includes: the controller, return air temperature sensor, coil pipe temperature sensor and ac contactor control relay. The outdoor unit includes: an ac contactor and a compressor.
Wherein, the controller is respectively connected with the return air temperature sensor, the coil pipe temperature sensor and the AC contactor control relay. The alternating current contactor control relay is connected with the alternating current contactor, and the alternating current contactor is connected with the compressor.
And the return air temperature sensor is arranged at an air inlet of the indoor unit and used for detecting the indoor environment temperature.
And the coil temperature sensor is arranged on an evaporator of the indoor unit and used for detecting the temperature of the indoor coil.
And the controller is used for acquiring a first indoor environment temperature from the return air temperature sensor after controlling the compressor to operate for a preset time period, acquiring an indoor coil temperature from the coil temperature sensor, and determining whether the compressor operates reversely according to the first indoor environment temperature and the indoor coil temperature. And the controller is also used for controlling the opening and closing of the compressor by controlling the alternating current contactor control relay. The alternating current contactor controls the relay and is used for controlling the alternating current contactor. And the alternating current contactor is used for controlling the opening and closing of the compressor. And the controller may be a Microprogrammed Control Unit (MCU).
Further, the indoor unit of the air conditioner may further include a display screen or an alarm device. Wherein, the controller is respectively connected with the display screen or the alarm device.
And the controller is also used for indicating the display screen to output alarm information after the compressor is determined to reversely rotate. Or the controller is also used for controlling the alarm device to give an alarm after the compressor is determined to reversely rotate, and the alarm duration is preset time so as to prompt a user that the compressor fails.
Fig. 2 is a flowchart of a method for detecting reverse rotation of a compressor according to an embodiment of the present invention, which can be applied to the air conditioner of fig. 1. As shown in fig. 2, the method may include steps 201-203:
201. after the air conditioner is started, the compressor is controlled to be started.
The indoor unit of the air conditioner comprises a controller, wherein the controller can control the air conditioner to be started after receiving a starting instruction of a user, controls an indoor fan of the indoor unit to operate, and controls a relay to control a compressor of an outdoor unit to be started by controlling an alternating current contactor according to the relation between the indoor environment temperature and the set temperature.
Further, the controller of the indoor unit may acquire the current operation mode before controlling the compressor to be turned on. The operation mode may be a default setting mode of the air conditioner, may be a recorded last operation mode, and may be an operation mode selected by a user through an application of a remote controller, a line controller, a terminal, and the like. Then, the controller of the indoor unit can acquire the second indoor environment temperature through the return air temperature sensor, and control the compressor to be started when determining that the magnitude relation between the second indoor environment temperature and the set temperature meets the starting condition of the compressor according to the operation mode. Otherwise, when the second indoor environment temperature is determined to be in a size relation with the set temperature and not to meet the starting condition of the compressor, the controller of the indoor unit can keep the indoor fan running, and obtains the indoor environment temperature again, and whether the obtained indoor environment temperature and the set temperature meet the starting condition of the compressor or not is judged according to the running mode.
The determining, by the controller of the indoor unit, that the magnitude relationship between the second indoor ambient temperature and the set temperature satisfies the starting condition of the compressor according to the operation mode may specifically include: if the operation mode is the cooling mode or the dehumidifying mode, the controller of the indoor unit may determine that the start condition of the compressor is satisfied when it is determined that the second indoor ambient temperature is greater than the set temperature of the corresponding mode. If the operation mode is the heating mode, the controller of the indoor unit may determine that the start condition of the compressor is satisfied when it is determined that the second indoor ambient temperature is less than the set temperature of the heating mode.
202. And acquiring a first indoor environment temperature and an indoor coil temperature after the compressor operates for a preset time period.
After the controller of the indoor unit controls the compressor to be started, the first indoor environment temperature can be obtained through the return air temperature sensor after the compressor is determined to run for the preset time period, and the indoor coil temperature is obtained through the coil temperature sensor.
Further, in the embodiment of the present invention, after the compressor operates for the preset time period, the controller of the indoor unit obtains the first indoor environment temperature and the indoor coil temperature, which may specifically include: the controller of the indoor unit judges whether the compressor is started for the first time after the air conditioner is started, and if the compressor is started for the first time after the air conditioner is started, the controller of the indoor unit can obtain a first indoor environment temperature and an indoor coil temperature after the compressor runs for a preset time period. Accordingly, if the compressor is not first turned on after the air conditioner is turned on, the operation state of the compressor can be maintained. Therefore, whether the compressor is reversed or not is detected only under the condition that the compressor is firstly started after the air conditioner is started, and if the running mode is switched after the detection, the compressor can be restarted without repeated detection.
203. And determining whether the compressor runs reversely according to the first indoor environment temperature and the indoor coil temperature.
After acquiring the first indoor environment temperature and the indoor coil temperature, the controller of the indoor unit can determine whether the compressor runs in a reverse rotation mode according to the first indoor environment temperature and the indoor coil temperature. Specifically, if the absolute value of the difference between the first indoor ambient temperature and the indoor coil temperature is less than or equal to a preset value, it indicates that the air conditioner cannot perform normal cooling or heating, and at this time, it is determined that the compressor is operated in reverse. If the absolute value of the difference value between the first indoor environment temperature and the indoor coil temperature is larger than the preset value, the fact that the air conditioner can normally refrigerate or heat is indicated, at the moment, the compressor is determined to normally operate, and the compressor and the indoor fan can be continuously kept to normally operate.
Further, in the embodiment of the present invention, after the controller of the indoor unit determines that the compressor operates in the reverse rotation mode, the controller may control the relay by controlling the ac contactor to control the compressor to stop operating, control the indoor fan to stop operating, and output the alarm information, where the alarm information is used to prompt a user that the compressor has a fault. In one implementation, a controller of the indoor unit may instruct a display screen to output alarm information. In another implementation manner, the controller of the indoor unit may control the alarm device to alarm, and the alarm time is a preset time duration.
According to the method for detecting the reverse rotation of the compressor, the controller of the indoor unit controls the compressor to be started after the air conditioner is started, the first indoor environment temperature and the indoor coil temperature are obtained after the compressor runs for the preset time period, and whether the compressor runs in the reverse rotation mode or not is determined according to the first indoor environment temperature and the indoor coil temperature. Therefore, under the conditions of normal operation and reverse operation of the compressor of the air conditioner, the difference value between the indoor environment temperature and the indoor coil temperature is different, and the controller of the indoor unit can acquire the indoor environment temperature and the indoor coil temperature, so that the controller of the indoor unit can determine whether the compressor operates normally or reversely according to the indoor environment temperature and the indoor coil temperature, and the reverse rotation detection of the compressor is realized.
