Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display screen according to the brightness of ambient light, and a proximity sensor that turns off the display screen and/or the backlight when the terminal device is moved to the ear. Of course, the air conditioner may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which are not described herein again.
Those skilled in the art will appreciate that the air conditioner configuration shown in fig. 1 is not intended to be limiting of the air conditioner and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer storage medium, may include therein an operating system, a network communication module, a user interface module, and an air conditioner control program.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call the air conditioner control program stored in the memory 1005 and perform the following operations:
detecting the indoor temperature and the outdoor temperature of the air conditioner during heating of the air conditioner;
controlling the compressor to operate according to the indoor temperature and the outdoor temperature; and/or
Detecting the tube temperature of the evaporator;
and controlling the fresh air machine to operate according to the pipe temperature.
The invention provides an air conditioner control method, in one embodiment of the air conditioner control method, the air conditioner control method comprises the following steps:
step S10, detecting the indoor temperature and the outdoor temperature of the air conditioner when the air conditioner heats;
the air conditioner control method in the embodiment is suitable for matching an outdoor fresh air fan with an indoor unit, and a pollutant infector is arranged at an air return inlet of the air conditioner and can identify air pollution media such as particulate matters, CO2 (carbon dioxide), VOC (volatile organic compounds) and the like. And when the pollutant infector detects that the air pollution medium reaches a certain threshold value, the alarm processing is carried out to prompt the user that the current air pollution degree is higher.
In this embodiment, the air conditioner control method is applied to an air conditioner including a compressor, an evaporator, an indoor unit, an air deflector, and a fresh air blower. And the fresh air machine assembly also comprises a fresh air machine assembly shell, a fresh air pipe and a HEPA (high efficiency particulate air) net (filter screen). In addition, in this embodiment, outdoor air is sent into the room by the outdoor fresh air fan through positive pressure, and is filtered by the filter screen, and is introduced into the evaporator of the indoor unit after being purified, and is sent into the room after being subjected to heat exchange. For example, as shown in fig. 4, the fresh air fan assembly comprises a fresh air fan assembly shell 1, a fresh air pipe 2, a HEPA net 3 and a wall 4. New fan subassembly casing 1, new tuber pipe 2 and HEPA net 3 are installed on wall body 4, and outdoor air is sent into indoorly by outdoor new fan malleation, filters, purifies through HEPA net 3 to send into the indoor set evaporimeter in new fan subassembly casing 1 through new tuber pipe 2, send to indoorly after the heat transfer.
In the embodiment, when the air conditioner is in heating and is controlled to prevent cold wind, the outdoor temperature is detected by the outdoor unit environment temperature sensing bulb, and when the outdoor temperature is lower than T1(T1 is less than or equal to 7 ℃), the fresh air function can be started and operated only in the heating mode. Therefore, when the air conditioner is controlled to prevent cold wind in winter, the environment temperature sensing bulb in the air conditioner is firstly used for detecting whether the outdoor temperature is lower than T1, if the outdoor temperature is lower than T1, and a user enters a cold wind prevention mode after a new wind function input through a remote controller or APP in a starting heating state. Therefore, in this embodiment, the outdoor temperature can be detected by, for example, detecting the ambient temperature bulb of the outdoor unit, and the indoor temperature needs to be detected while detecting the outdoor temperature, and the indoor temperature can be detected by obtaining a fresh air command input by the user through the remote controller or APP, and detecting the indoor temperature within the preset time period according to the fresh air command, that is, the air conditioner detects the indoor temperature of the environment where the air conditioner is located through, for example, the temperature sensor within a continuous preset time period (e.g., 10 minutes).
Step S20, controlling the compressor to operate according to the indoor temperature and the outdoor temperature;
when the indoor temperature and the outdoor temperature of the air conditioner are detected, whether the outdoor temperature is in a low temperature state or not needs to be determined, and if the outdoor temperature T is less than or equal to 7 ℃. If the indoor temperature is higher than or equal to the first preset temperature (such as 20 ℃), detecting the indoor temperature, namely detecting whether the indoor temperature is higher than or equal to the first preset temperature or not, if the indoor temperature is higher than or equal to the first preset temperature, determining that the air conditioner enters a low-frequency starting mode, controlling the compressor to start at a low frequency (such as 20 hz-30 hz) according to the low-frequency starting mode, and slowly increasing the frequency to avoid that too much cold air outdoors is blown into the room to cause the indoor temperature to be reduced. If the indoor temperature is lower than the first preset temperature, whether the indoor temperature is higher than or equal to a third preset temperature (such as 10 ℃) or not needs to be detected, if so, the air conditioner is determined to enter a low-frequency starting mode, the compressor is controlled to be started at a low frequency (such as 20 hz-30 hz) according to the low-frequency starting mode, and the frequency is slowly increased. If the indoor temperature is lower than the third preset temperature, the air conditioner enters a high-frequency starting mode, and the compressor is controlled to start at a higher frequency (such as 70 hz-90 hz) according to the high-frequency starting mode and to increase the frequency. Wherein, the low frequency starting mode is that the air conditioner controls the compressor to start at a low frequency (such as 20 hz-30 hz). The high frequency starting mode is that the air conditioner controls the compressor to start at a high frequency (for example, 70hz to 90 hz).
For example, if the indoor temperature Ti is monitored TO be more than or equal TO 20 ℃ and the outdoor temperature TO is monitored TO be less than or equal TO 7 ℃ continuously for 10 minutes, the indoor heating equipment is judged TO be operated, the output of the compressor is irrelevant TO the set temperature of the remote controller, only the minimum output for offsetting the hot air load is ensured, and when the indoor temperature Ti is more than or equal TO 20 ℃ and the outdoor temperature TO is less than or equal TO 7 ℃, the air conditioner enters a low-frequency starting mode, the compressor is started at 20hz TO 30hz, and the frequency is slowly increased. If the indoor temperature is monitored TO be more than or equal TO 10 ℃ and less than 20 ℃ and the outdoor temperature TO is less than or equal TO 7 ℃ continuously for 10 minutes, the indoor heating equipment is judged TO be operated, but the heating quantity is limited, the output of the compressor is operated according TO normal logic, namely, the maximum heating frequency is determined according TO the temperature set by the remote controller, the windshield of the fresh air fan is not limited, when the indoor temperature is more than or equal TO 10 ℃ and less than 20 ℃ and the outdoor temperature T is less than or equal TO 7 ℃, the air conditioner enters a low-frequency starting mode, and the compressor is started at 20hz TO 30hz and slowly increases. If the indoor temperature Ti is monitored TO be less than 10 ℃ and the outdoor temperature TO is monitored TO be less than or equal TO 7 ℃ continuously for 10 minutes, the indoor operation without heating equipment is judged, the output of the compressor operates according TO normal logic, and the fresh air fan can only open a middle-grade or lower windshield in an automatic mode, so that the minimum fresh air requirement is ensured, and the energy consumption is saved. And when the indoor temperature Ti is less than 10 ℃ and the outdoor temperature T is less than or equal to 7 ℃, the air conditioner enters a high-frequency starting mode, and the compressor is started at 70hz to 90hz and is subjected to frequency raising.
Step S30, and/or detecting the tube temperature of the evaporator;
and step S40, controlling the fresh air fan to operate according to the pipe temperature.
After the compressor is operated, the temperature of the evaporator can be detected, and whether the temperature of the evaporator is higher than a preset set temperature t (which can be set by a user, generally, t is preferably more than or equal to 35 ℃ and less than or equal to 45 ℃) can be determined. If the temperature of the pipe is higher than the preset set temperature, the frequency starting mode of the air conditioner needs to be determined, if the frequency starting mode of the air conditioner is the low-frequency starting mode, the windshield of the indoor unit of the fresh air fan is controlled to operate in a set windshield mode, the air deflector is turned to a cold air prevention angle, and the windshield of the fresh air fan operates in a set windshield mode. The set windshield may include high gear, medium gear, low gear, etc. However, if the frequency starting mode of the air conditioner is the high-frequency starting mode, the windshield of the indoor unit of the fresh air fan needs to be controlled to set the windshield to operate, the air deflector is turned to the cold wind prevention angle, and the windshield of the fresh air fan operates at the low windshield. The set temperature t can be any temperature, and is not limited to 35 ℃ to 45 ℃ in the embodiment. And wind speeds are generally classified into three major categories of high, medium and low windshields in an air conditioner.
It should be noted that in this embodiment, when the outdoor temperature detected by the outdoor unit environmental thermometer bulb is lower than T1(T1 is less than or equal to 7 ℃), the fresh air function can only be started and operated in the heating mode; the compressor frequency is subjected TO load judgment by taking the outdoor temperature TO and the indoor temperature Ti as references, the provided heating capacity is equivalent TO the heat load increased by fresh air, and the energy consumption is not additionally increased; the fresh air fan wind shield, the indoor unit wind shield, the compressor starting mode and the air deflector angle are all related to the indoor temperature and the evaporator tube temperature; and judging whether heating equipment exists or not in the room according to different indoor temperatures, and providing different linkage schemes of a fresh air fan damper, an indoor unit damper and an air deflector.
In addition, in order to assist understanding of the principle of the air conditioner cold prevention function in the present embodiment, an example will be described below.
For example, as shown in fig. 5, in the winter cold air prevention control method for the fresh air conditioner, the outdoor temperature is detected by the outdoor unit environment temperature sensing bulb to serve as the cold air prevention control entry condition, and the entry condition further requires obtaining the button selection of the user for the "fresh air" control, that is, the user selects "fresh air" by the remote controller or the APP in the power-on state, and selects "fire-fighting cold air" by the button selection to exit the cold air prevention function. Then the outdoor air is sent into the room by positive pressure, and is introduced to the evaporator of the indoor unit after being filtered, and is sent into the room after heat exchange. And the entering mode of entering cold-proof wind is that when the outdoor temperature detected by the environment temperature sensing bulb is lower than T, the fresh air function can only be started in the heating mode, and the user selects the fresh air function through the remote controller or the APP and then enters the cold-proof wind mode in the starting and heating state, wherein T can be any value, and if T is set to be less than or equal to 15 ℃, T is less than or equal to 15 ℃. And after the air conditioner starts the cold air prevention mode, the execution process of the air conditioner is to obtain the indoor temperature firstly.
