The indoor control panel 100 and the outdoor control panel 200 communicate with each other, and the outdoor control panel 200 transmits the operation states and environmental parameters of the components of the outdoor unit to the indoor control panel 100, for example, various temperature sensors are further provided in the outdoor unit to detect the outdoor ambient temperature, the compressor discharge temperature, the outdoor heat exchanger temperature, and the like. The indoor unit control panel 100 generates a corresponding control command by combining the operation state and the environmental parameters of each component of the indoor unit, and adjusts the operation of each component of the air conditioner. For example, various temperature sensors are also provided in the indoor unit to detect the indoor ambient temperature and the indoor heat exchanger temperature.
In addition, the indoor unit control panel 100 can also receive control commands sent by the control terminal 300, such as mode setting, indoor target temperature setting, indoor target humidity setting, windshield setting, and the like, to adjust the operating parameters of the air conditioner.
As shown in fig. 2, an operation parameter control flow of an air conditioner according to the present invention is shown. The operation parameter control method of the air conditioner may include the steps of:
step S110, obtaining an operation parameter range allowed to be controlled in the operation process of the air conditioner, and displaying the operation parameter range to a user through a user interaction interface;
in the embodiment of the invention, a preset specific mode, such as a manual mode, is set. The user can send a mode setting command through the control terminal 300 to enable the air conditioner to enter a manual mode. That is, a preset specific mode setting command is received, and the air conditioner enters the specific mode, that is, a manual mode. In order to prevent the effective use of the air conditioner, when the user needs to enter the manual mode, the user is authenticated, and the manual mode is allowed to enter if the authentication is passed. The authentication is carried out through a user account and a password, and the user is allowed to enter the manual mode when the user has the authority of the manual mode.
The operation parameter range allowed to be controlled in the air conditioner operation process refers to a parameter range which can be adjusted by the air conditioner. The operation parameter refers to operation parameters of each component of the air conditioner, such as a frequency parameter of a compressor, a rotating speed parameter of an indoor fan, a rotating speed parameter of an outdoor fan, an opening degree parameter of an electronic expansion valve and the like, and the operation parameters are single or a combination of a plurality of parameters.
And after the operation parameter range is obtained, displaying the operation parameter range to a user through a user interactive interface. The user interaction interface can be displayed by an electronic display screen, and the electronic display screen can be arranged on an air conditioner panel and also can be arranged on other terminals, such as a mobile phone terminal and a remote controller which can control an air conditioner.

And S130, setting operation parameters of the air conditioner corresponding to the parameter setting instructions according to the parameter setting instructions.
The air conditioner receives the parameter setting instruction and sends a control instruction to the corresponding component of the air conditioner according to the parameter value so as to control the running state of each component of the air conditioner.
According to the invention, a specific mode is set, and under the specific mode, a user can set the operation parameters of each component of the air conditioner according to the needs of the user, and the setting of the parameters set during the development of the air conditioner is not limited. Therefore, the invention can meet different user requirements and scene requirements, and especially meet the requirements of air-conditioning enthusiasts.
Further, as shown in fig. 4, the step S110 may include:
step S111, obtaining an ambient temperature;
the ambient temperature may include an outdoor ambient temperature and an indoor ambient temperature. The indoor ambient temperature may be detected by a temperature sensor provided in the indoor unit, and the outdoor ambient temperature may be detected by a temperature sensor provided in the outdoor unit. In addition, the outdoor ambient temperature may be obtained from weather forecast data obtained by the air conditioner accessing an external network. Both the indoor ambient temperature and the outdoor ambient temperature will be fed back to the indoor unit control board 100.
Step S112, obtaining the lowest operation frequency T allowed by the compressor of the air conditioner according to the environment temperatureLAnd the highest operating frequency THAnd setting the operation parameter range of the compressor allowable control in the air conditioner operation process as TL，TH]。
In this embodiment, the ambient temperature and the lowest allowable operating frequency T of the compressor of the air conditioner may be presetLMaximum operating frequency THThe mapping relationship between them. Wherein, TLHas a value range of [1Hz, 15Hz]. The indoor unit control panel 100 may obtain the lowest operation frequency T of the allowed operation of the compressor of the air conditioner corresponding to the ambient temperature according to the ambient temperature obtained in step S111 and the preset mapping relationshipLE.g. 1Hz, and the maximum operating frequency T allowed for operationHFor example 100 Hz. At this time, the operation parameter range of the compressor allowing control during the operation of the air conditioner is set to [ T ]L，TH]E.g. [1Hz, 100Hz]. The indoor unit control panel 100 transmits the obtained compressor frequency range to the control terminal 300 for the user to perform frequency setting.
Based on the obtained compressor frequency range, the user may set specific frequency values, such as 80Hz, 65Hz, 78Hz, and the like. Of course, frequency ranges may be provided, such as 10-80Hz, 5-70Hz, etc. The control end 300 sends the set frequency parameter to the indoor unit control panel 100, so that the indoor unit control panel 100 adjusts the compressor operation frequency according to the set frequency parameter.
Further, the step S110 may further include: identifying a speed range [ R ] of an indoor fan and/or an outdoor fanL，RH]And setting the operation parameter range of the fan allowable control in the air conditioner operation process as RL，RH]. Specifically, the indoor unit control panel 100 may obtain an operation parameter of the indoor fan, and identify a minimum rotation speed and a maximum rotation speed of the indoor fan; the outdoor control panel 200 may also obtain the operating parameters of the outdoor fan, identify the lowest rotation speed and the highest rotation speed of the outdoor fan, and transmit the identified rotation speed range to the indoor control panel 100. Indoor unit control panel 100 recognizes the range of indoor fan rotation speed [ R ]In L，RIn H]And/or outdoor fan speed range [ R ]L outer layer，RH outer]And sent to the control terminal 300 for the user to set the rotation speed.
The control end 300 sends the set fan rotation speed parameter to the indoor unit control panel 100, so that the indoor unit control panel 100 adjusts the fan rotation speed according to the set fan rotation speed parameter. If the fan has a resonance rotation speed, the indoor unit control panel 100 is preset with a resonance rotation speed range, i.e., a resonance area. When the set fan rotating speed falls in the resonance area, the actual rotating speed is set to be higher, the value is taken upwards, and if the actual rotating speed is set to be lower, the value is taken downwards. For example, the resonant rotation speed of the fan of a certain machine type is 680-700 rpm, the current operation rotation speed is 800 rpm, the newly set rotation speed is 690 rpm, the 800 rpm is set to 690 rpm toward the low, and the current operation rotation speed is just in the resonant zone, so the current operation rotation speed is actually taken down, for example, 679 rpm.
Further, the step S110 includes: and acquiring the adjustable opening range of the electronic expansion valve, and setting the operation parameter range allowed to be controlled by the electronic expansion valve in the operation process of the air conditioner as the acquired opening range. Specifically, the outdoor unit control board 200 obtains the adjustable opening range of the electronic expansion valve, for example, the minimum value is generally 60-80, and the maximum value is generally 480-520, for example, 80-480. The outdoor control panel 200 transmits the acquired opening range to the indoor control panel 100, and the indoor control panel 100 transmits the acquired opening range to the control terminal 300, so that the user can set the opening. The user may set a specific value of the opening degree range, preferably an even number. The control end 300 sends the set opening parameter to the indoor unit control panel 100, and the indoor unit control panel 100 controls the electronic expansion valve to open to the numerical opening.
Further, as shown in fig. 5, the method for controlling the operation parameters of the air conditioner further includes:
step S140, monitoring the running state of each component of the air conditioner;
the operating states of the components may include: compressor discharge temperature, indoor heat exchanger temperature, outdoor heat exchanger temperature, current, voltage, etc.
And S150, controlling the air conditioner to perform corresponding protection when the running state of each component meets the preset protection condition.
In this embodiment, the preset protection condition may include: the compressor has the disadvantages of overhigh exhaust temperature, overhigh temperature of the indoor heat exchanger, overlow temperature of the indoor heat exchanger, overhigh temperature of the outdoor heat exchanger, frequency limitation of current, frequency limitation of voltage and the like. For example, the compressor discharge temperature cannot be below a preset temperature threshold; the current or voltage is small and the highest frequency that can operate is also small. When the operation state of each component meets the preset protection condition, the air conditioner is controlled to perform corresponding protection, such as limiting the operation frequency of the compressor, reducing the rotating speed of the fan, even turning off the compressor and the like. Of course, the protection information may be sent to the control terminal 300 to prompt the user to perform timely processing, and at the same time, some other prompt information may be given to the user, for example, the benefit of such protection, the disadvantage of no protection,
in order to ensure that the air conditioner runs in a manual mode, the running state of each component of the current air conditioner is detected to meet the preset protection condition, namely the air conditioner is protected due to damage, and the air conditioner is controlled to carry out corresponding protection in time so as to avoid the damage of the air conditioner.
An example of the use of the air conditioner in the manual mode will be listed below:
usage scenario 1
When the user A uses the air conditioner, the user A feels that the air outlet when the air conditioner automatically runs is too cold and just blows towards the air conditioner, so that the user A is uncomfortable. At this time, the user can turn to the manual mode to adjust the frequency of the compressor to be low, the rotating speed of the outdoor fan to be low, the rotating speed of the indoor fan to be high, and the electronic expansion valve to be low. Thus, the temperature of the outlet air is increased, for example, 26 ℃, and the outlet air of the air conditioner is comfortable to blow on the body.
Usage scenario 2
User B suddenly received a complaint from the building while using the air conditioner, reflecting that the outdoor fan was noisy. At this time, the frequency of the compressor and the rotation speed of the outdoor fan may be reduced.
Usage scenario 3
When the user C uses the air conditioner, the user C finds that the air outlet temperature of the air outlet of the air conditioner is 14 ℃, the air outlet temperature is not cold enough, the air outlet temperature of the air outlet is expected to be ultralow-temperature air of 8 ℃, the frequency of the compressor can be increased, the rotating speed of the indoor fan is adjusted to be the lowest, and therefore ice air of 4 ℃ can be blown out.
Usage scenario 4
The current outdoor temperature is 30 c and user D wishes to steam a "sauna" in the room, at which time you can turn on the manual mode to let the room temperature rise to 40 c or even 50 c. In the automatic mode of the air conditioner, the maximum temperature can be set to be only 30 ℃, and the air conditioner can be automatically stopped when the temperature is higher, and the limitation can be eliminated through the manual mode, so that a wider temperature regulation range is provided.
