Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
An embodiment of the present invention provides an operation method of a full-direct-current solar inverter air conditioner, which is applied to an internal unit of the inverter air conditioner, as shown in fig. 1, the inverter air conditioner specifically includes an internal unit 101 and an external unit 102, a compressor 103 is disposed in the external unit 102, and the control of the internal unit 101 is realized by an air conditioner remote controller. Specifically, the external unit includes an MCU (microprocessor) 104, a control module 105, and a compressor power module 106, where the compressor power module 106 is connected to the compressor 103, and the MCU may also receive system control, sensing control, ac control, and the like. The system control may be a control directly performed on the external unit 102 by connecting a special system device, the sensing control may specifically be information detected by a sensor, a control performed based on the information detected by the sensor, and the communication control may specifically be a voice control, or the like.
The inner unit 101 is connected to the MCU104 of the outer unit 102, and the inner unit 101 can be remotely controlled by a remote controller or the like.
The execution main body of the method is the internal machine. As shown in fig. 2, includes: s201, receiving a first control instruction and a set temperature value; s202, judging whether the first control instruction is a preset instruction or not; s203, when the preset instruction is determined, sending first communication data to an external unit of the variable frequency air conditioner so as to enable the compressor to operate at a first preset frequency; s203, obtaining a target adjusting frequency of the compressor based on the set temperature value and the current actual temperature value, and controlling the compressor to operate at the target adjusting frequency after the compressor operates at the first preset frequency for a first preset time.
S201, receiving a first control instruction and a set temperature value.
Specifically, a first control instruction of an air conditioner remote controller is received, specifically, the air conditioner remote controller is used for controlling the variable frequency air conditioner to be started and selecting an operation mode, and a temperature value to be adjusted is set in the corresponding operation mode.
The operation mode in the first control instruction may specifically be any one of a ventilation mode, a cooling mode, a heating mode, a dehumidification mode, a mildew-proof mode and a cleaning mode. Of course, other operation modes may be available, and are not described in detail in the embodiment of the present invention.
Next, S202 is executed to determine whether the first control instruction is a preset instruction, where the preset instruction specifically includes any one of the following:
a cooling command, a heating command and a dehumidification command.
Then, S203 is executed, and when the preset command is determined, first communication data is sent to an external unit of the inverter air conditioner, so that the compressor operates at a first preset frequency.
Specifically, when it is determined that the first control instruction is any one of a heating instruction, a cooling instruction, and a dehumidification instruction, the internal unit sends first communication data to the external unit of the inverter air conditioner, where the first communication data specifically includes: the method comprises the following steps of specifically communicating a command value, setting a temperature value, setting a mode, starting frequency of the compressor and the like, so that the compressor is started to operate at a first preset frequency. The first preset frequency is 40-60 Hz, preferably 50Hz, and the starting time is 200ms at the preferred starting frequency of 50 Hz.
Then, S204 is executed, a target adjustment frequency of the compressor is obtained based on the set temperature value and the current actual temperature value, and after the compressor is started to operate at the first preset frequency for a first preset time period, the compressor is controlled to operate at the target adjustment frequency.
In a specific embodiment, the set temperature value is specifically a temperature value set on a remote controller of an air conditioner, and the current actual temperature value is specifically a temperature value of the current room temperature.
The process of obtaining the target adjustment frequency is specifically as follows:
based on the set temperature value, obtaining a per unit value of the set temperature value,
obtaining a per unit value of the actual temperature value based on the current actual temperature value;
based on the per unit value of the set temperature value and the per unit value of the actual temperature value, obtaining the target adjusting frequency of the compressor according to the following formula:
Fobj＝K*(Tobj-Treal)/Fpwm
wherein, Fobj is a target adjusting frequency, Tobj is a per unit value of a set temperature value, Treal is a per unit value of an actual temperature value, Fpwm is a current loop bandwidth of the motor for driving the compressor to operate, and K is an adjusting gain of the target adjusting frequency. Moreover, the adjustment gain of the target adjustment frequency is determined by the speed change adjustment bandwidth in the cooling and heating mode.
The per unit value of the set temperature value is specifically a ratio of the set value of the temperature value to a basic value thereof, and the basic value is a value that can be set. Similarly, the per unit value of the actual temperature value is specifically a ratio of the actual temperature value to a basic value thereof, and the basic value may be different from the above basic value.
The target adjustment frequency thus determined is determined from the set temperature value and the actual temperature value, and therefore, the operating frequency of the corresponding compressor after start-up is also different for different temperature setting modes.
And after the compressor is started to operate at the first preset frequency for a first preset time, the internal machine controls the compressor to operate at the target adjusting frequency.
Taking the first preset frequency of 50Hz for starting as an example, the first preset time period corresponds to less than or equal to 2min, so that after the compressor is started and operated for the first preset time period at 50Hz, the compressor is operated according to the target adjustment frequency.
The adopted compressor starting technology is specifically a PCL (pre-closed loop) starting technology, so that the starting efficiency of the compressor is improved, and after the compressor runs stably, the compressor is adjusted to a proper target adjusting temperature according to a set temperature value and an actual temperature value, and the running efficiency of the compressor is also improved.
If it is determined that the first control command is not the preset command after determining whether the first control command is the preset command in S202, the indoor unit does not need to communicate with the outdoor unit.
In a preferred embodiment, S203 specifically includes: and when the preset command is determined, sending first communication data to an external unit of the variable frequency air conditioner at a first transmission rate so as to start the compressor to operate at a first preset frequency.
Specifically, the first transmission rate is specifically 6000bps to 14000bps, preferably 9600 bps. When the first communication data is transmitted at the first transmission rate of 9600bps, the amount of data to be communicated is 20 bytes per frame, the handshake waiting interval for communication is 5ms, and the transmission cycle is 50 ms. The sending times are specifically 5-10 times, so that the data can be completely transmitted. The first communication data specifically includes: the method comprises the following steps of specifically communicating a command value, setting a temperature value, setting a mode, starting frequency of the compressor and the like, so that the compressor is started to operate at a first preset frequency.
After S203, further comprising:
and sending second communication data to an external unit of the variable frequency air conditioner at a second transmission rate, wherein the second transmission rate is less than the first transmission rate.
The second transmission rate is specifically 300 to 2400bps, preferably 1200bps, and when the second communication data is transmitted at the second transmission rate of 1200bps, the amount of data to be communicated is 20 bytes in one frame, of course, the amount of data to be transmitted in one frame may be set according to the communication condition, the handshake waiting interval of communication is 20ms, and the transmission period is 500 ms. The second communication data specifically includes an operating current, an operating voltage, an operating frequency, and the like of the compressor.
The method and the device send first communication data to the outdoor unit of the inverter air conditioner at a first transmission rate before the compressor is started, send second communication data to the outdoor unit of the inverter air conditioner at a second transmission rate after the compressor is started, wherein the second transmission rate is smaller than the first transmission rate, and the EMC (electromagnetic compatibility test, comprehensive evaluation of the interference of the equipment on the aspect of electromagnetic field and the anti-interference capability) can be conveniently passed. And the first transmission rate with higher speed is adopted for communication before the compressor is started, so that the communication time is shortened, the efficiency of starting the compressor is improved, and the refrigerating or heating efficiency of the inverter air conditioner is improved as a whole.
In a preferred embodiment, in the operation method of the all-direct-current solar inverter air conditioner, communication faults of an inner machine and an outer machine and starting faults of a compressor can be encountered.
Specifically, in the execution process of S203, when it is determined that the command is the preset command, the sending of the first communication data to the outdoor unit of the inverter air conditioner includes:
detecting whether response data of an external unit is received;
when the response data of the external machine is not received, determining the external machine to be a communication fault;
until the response data is received, the communication fault is relieved, and the compressor is controlled to start running at a second preset frequency.
In a specific embodiment, if the internal unit sends data to the external unit and the external unit does not feed back response data to the internal unit for 20s, it is determined that there is a communication failure, and at this time, the first transmission rate may be switched to the second transmission rate, that is, the transmission rate is reduced. And meanwhile, when the internal machine receives the response data, the communication fault is relieved, and the compressor is controlled to start running at a second preset frequency.
The second preset frequency is 5-10 Hz, and the second preset frequency is smaller than the first preset frequency, so that the starting speed is low, and the mode of starting operation by the second preset frequency is a normal starting mode.
In a preferred embodiment, the method further comprises:
detecting whether a fault signal fed back by the compressor is received;
timing the fault time of the compressor when a fault signal fed back by the compressor is received;
and when the fault duration reaches a second preset duration, clearing the fault signal and timing of the compressor, and re-executing the step of judging whether the first control instruction is a preset instruction or not so as to restart.
The compressor can confirm whether it is out of order, i.e., determine whether it is out of order by detecting data of its own operation.
Wherein the second preset time period is specifically 2-3 minutes.
The measures corresponding to the two faults are adopted, the compressor can be guided to start, and the effects of refrigeration, heating and dehumidification are achieved.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
the invention provides an operation method of a full direct current solar variable frequency air conditioner, which comprises the following steps: receiving a first control instruction and a set temperature value, and judging whether the first control instruction is a preset instruction or not; when the preset instruction is determined, sending first communication data to an external unit of the variable frequency air conditioner so as to enable the compressor to operate at a first preset frequency; and obtaining the target adjusting frequency of the compressor based on the preset temperature value and the current actual temperature value, and controlling the compressor to operate at the target adjusting frequency after the compressor operates at the first preset frequency for a first preset time, so that the starting time of the variable frequency air conditioner is effectively saved, and the purposes of refrigerating and heating are quickly achieved.
