In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein, and it will be apparent to those of ordinary skill in the art that the present application is not limited by the specific embodiments disclosed below.

In order to solve the problems, the application provides an air conditioner operation method and system, cold air is prevented from being sent out when the air conditioner is started to heat by closing an air deflector, the cold air prevention effect is achieved, an electric heating device is controlled to start electric heating, the temperature of a coil pipe in the air conditioner can be quickly improved by using heat generated by the electric heating device, the problem that the air conditioner sends out the cold air when the air conditioner is started at a low temperature is solved, and uncomfortable experience is avoided being brought to a user.
For convenience of understanding, an air conditioner operation method and system provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of an air conditioner operation method provided in an embodiment of the present application may include the following steps:
s101: and when the air conditioner is started, the air conditioner enters a cold air prevention state under the condition that the air conditioner is in a heating mode.
In the embodiment of the application, when the machine operation mode of the air conditioner is a heating mode, namely when the air conditioner is started for heating, the air conditioner enters a cold air prevention state; the cold air preventing state can avoid sending out cold air when the air conditioner is started to heat in cold weather. The heating mode of the air conditioner can be automatically started after the machine is started, for example, when the indoor environment temperature is detected to be lower than the preset indoor temperature, the air conditioner automatically enters the heating mode; in another possible implementation manner, the air conditioner receives a request for starting a heating mode, which is actively sent by a user, and enters the heating mode. Specifically, the indoor ambient temperature can be detected by an ambient temperature sensor of the indoor unit of the air conditioner. Referring to fig. 2, a cross-sectional structure diagram of an indoor unit of an air conditioner according to an embodiment of the present application is shown in fig. 2, where an ambient temperature sensor is deployed in the indoor unit of the air conditioner, and the ambient temperature sensor is capable of detecting an indoor environment temperature.
S102: and under the cold air prevention state, keeping the air deflector of the air conditioner closed, and controlling an electric heating device of the air conditioner to start heating.
The electric heating device is positioned in the indoor unit of the air conditioner, and the heat generated by the electric heating device is used for increasing the temperature of the inner coil pipe of the air conditioner.
In the embodiment of the application, the air deflector of the air conditioner is kept closed in the cold air prevention state. The air conditioner air deflector is an air guide device installed on an air conditioner indoor unit, and mainly has the main effects of assisting in adjusting the air direction of an air conditioner and avoiding uncomfortable experience of direct blowing of the air conditioner to a user. If the air conditioner air deflector is in an open state when being started, the air conditioner air deflector is closed after entering a cold air prevention state; if the air conditioner air deflector is in a closed state when being started, the opening operation of the air conditioner air deflector is not carried out in a cold air prevention state. Referring to fig. 3, another cross-sectional structure diagram of an indoor unit of an air conditioner according to an embodiment of the present disclosure is shown; as shown in fig. 2 and 3, the air deflector is located outside the indoor unit of the air conditioner, so that cold air of the air conditioner cannot be sent into the room under the condition that the air deflector is not opened, and the cold air is prevented from being sent out when the air conditioner is started to heat.
In the related art, the cold air preventing function of some air conditioner configurations is mainly realized by only operating the outdoor unit of the air conditioner, and the realization method has the following disadvantages: when indoor outer ambient temperature is lower, the time of preventing cold wind is longer, need wait for longer time after the start, and user experience is relatively poor.
As shown in fig. 2 and 3, the electric heating device is located in an indoor unit of an air conditioner, and the electric heating device mainly plays a role of auxiliary heating. In some possible implementations, the electric heating device may be arranged annularly in the air conditioning indoor unit; the inner coil of the air conditioner can be arranged near the electric heating device, and when chilled water or hot water flows through the inner coil of the air conditioner, heat exchange is carried out between the inner coil of the air conditioner and air outside the pipe, so that the effect of regulating the temperature of indoor air is achieved. In some possible implementation modes, the air conditioner internal coil is close to the air supply outlet of the air conditioner indoor unit, so that the temperature of the internal coil is close to the air supply temperature of the air conditioner indoor unit. The heat that the electric heating device produced can improve the interior coil pipe temperature of air conditioner fast, solves the air conditioner and sends out cold wind problem when starting at low temperature, shortens the time of preventing cold wind, has improved user experience.
Currently, the cold air prevention function of some air conditioner configurations is mainly implemented by operating only the outdoor unit of the air conditioner, and the indoor unit of the air conditioner is not turned on until the temperature of the internal coil reaches a starting temperature (e.g., 30 degrees celsius) or higher. The realization method can independently operate the air-conditioning indoor unit under the condition of closing the air-conditioning indoor unit, and has the following problems: if the temperature of the inner coil pipe cannot reach the starting temperature for a long time, the air conditioner outdoor unit runs for a long time at high frequency while the air conditioner indoor unit is not started, so that the phenomenon of overhigh pressure or overcurrent of an air conditioning system is easily caused, the air conditioner is stopped, and the problems of shortening the service life of the machine, generating safety risks and the like are possibly caused.
In a possible implementation manner provided by the embodiment of the application, the air conditioner outdoor unit can be controlled to be in a stop operation state in a cold air prevention state, the coil pipe in the air conditioner can be heated only by the electric heating device, and risk hazards such as overhigh pressure, overcurrent and the like caused by the operation of the air conditioner outdoor unit can be avoided because the air conditioner outdoor unit is not operated in the implementation manner.
In another possible implementation manner provided by the embodiment of the present application, the following steps may be performed after entering the cold air prevention state:
after the cold air prevention state is started for a preset time, if the temperature of the inner coil is detected to be lower than the preset temperature, the outer fan of the air conditioner is controlled to operate at a rotating speed lower than a first rotating speed, and the outdoor compressor of the air conditioner is controlled to operate at a frequency lower than a first preset frequency.
In the embodiment of the application, the outdoor unit of the air conditioner comprises the external fan and the outdoor compressor, wherein the external fan of the air conditioner mainly has the function of providing a heat dissipation function for the condenser of the air conditioner, so that the heat exchange efficiency of the condenser can be improved; the outdoor compressor is used for compressing and driving refrigerant. After entering the cold air prevention state for a preset time, for example, after entering the cold air prevention state for 2 minutes, if it is detected that the temperature of the inner coil is still lower than a preset temperature (for example, 30 ℃), the low-power operation of the air conditioner outdoor unit may be controlled, and the temperature rise of the inner coil is assisted.
The air conditioner comprises an air conditioner, a control unit and a control unit, wherein the air conditioner can be controlled to operate at a low rotating speed, specifically can operate at a rotating speed less than a first rotating speed, and the first rotating speed can be less than or equal to the rotating speed at which the air conditioner normally operates; the method includes controlling low-frequency operation of an outdoor compressor of the air conditioner, specifically, operating at a frequency less than a first preset frequency, where the first preset frequency may be less than or equal to a normal operating frequency of the outdoor compressor. For example, if the normal operation frequency of the outdoor compressor is 70hz, the outdoor compressor is operated at a frequency of 20hz in the cold air prevention state. On one hand, the outdoor unit of the air conditioner can absorb heat from the outdoor environment to assist the temperature rise of the inner coil pipe; on the other hand, the air conditioner outdoor unit operates under low power, so that the risk hazards of overhigh pressure, overcurrent and the like caused by the operation of the air conditioner outdoor unit can be avoided.
In another possible implementation manner provided by the embodiment of the present application, the first rotation speed and the first preset frequency may be predetermined according to the following method: and detecting the outdoor temperature, and determining the first rotating speed and the first preset frequency according to the outdoor temperature.
In the embodiment of the present application, since the capacity of the outdoor unit of the air conditioner to absorb heat from the outdoor environment is affected by the temperature of the outdoor environment, for example, when the outdoor unit of the air conditioner operates at the same power, the heat absorption rate of the outdoor unit of the air conditioner is slower when the outdoor temperature is lower than when the outdoor temperature is higher. When the outdoor temperature is low, the heat absorption rate of the outdoor unit of the air conditioner can be improved by properly improving the rotating speed of the outer fan of the air conditioner and the frequency of the outdoor compressor, so that the temperature rise time of the temperature of the inner coil is further shortened; when the outdoor temperature is higher, the rotating speed of the external fan and the frequency of the outdoor compressor can be correspondingly reduced, and the waste of energy is avoided. Therefore, the corresponding relation between the outdoor temperature and the first rotating speed and the first preset frequency can be predetermined, and the upper limits of the rotating speed of the outer fan and the frequency of the outdoor compressor are automatically adjusted based on the corresponding relation under different outdoor temperatures, so that the heating efficiency of the inner coil pipe is ensured on the premise of avoiding overhigh pressure and overcurrent caused by the operation of the outdoor unit of the air conditioner. Specifically, the outdoor temperature may be detected by an outdoor ambient temperature sensor disposed on the outdoor unit of the air conditioner.
The related art described above also has the following problems: when cold wind is prevented, the indoor unit of the air conditioner is not opened, so that the heat exchangers inside and outside the air conditioner cannot fully utilize heat, more heat is lost when heat exchange is carried out, and the energy utilization rate is low.
In another possible implementation manner provided by the embodiment of the present application, the following steps may be performed in a cold air prevention state:
and under the cold air prevention state, controlling an inner fan of the air conditioner to operate, wherein the inner fan is positioned in the indoor unit of the air conditioner and is used for enabling heat generated by the electric heating device to circulate in the indoor unit of the air conditioner.
In the embodiment of the application, in the cold air prevention state, the operation of the inner fan of the air conditioner can be controlled, and the inner fan of the air conditioner mainly plays a role in heat exchange. The inner fan is located in an indoor unit of the air conditioner, and specific deployment positions can refer to fig. 2 and fig. 3. On one hand, the operation of the inner fan can promote the heat circulation in the air-conditioning indoor unit, and prevent the heat generated by the electric heating device from being concentrated in a certain area to cause the overall temperature rise of the inner coil to be slower, so that the heat is uniformly distributed as far as possible, the heat loss is reduced, and the utilization rate of the heat generated by the electric heating device is improved; on the other hand, compared with the implementation mode of the prior art introduced above, in a cold air prevention state, if the air conditioner outdoor unit is started, the pressure of the air conditioner system can be balanced through the operation of the internal fan, the risks of overhigh pressure and overcurrent caused by only starting the air conditioner outdoor unit are avoided, the heat of the heat exchanger can be fully utilized, and the heat loss is also reduced; the heat exchanger of the air conditioner can recover heat from air, and the heat loss in the operation of the air conditioner is reduced.
In a possible implementation mode, the operation of the fan in the air conditioner is controlled firstly in the cold air prevention state, and the operation of the outdoor unit of the air conditioner is controlled after the state of the cold air prevention state is entered for a period of time, so that the problems of overhigh pressure, overcurrent and the like caused by the fact that the outdoor unit of the air conditioner is started firstly and then the indoor unit of the air conditioner is started can be prevented.
In another possible implementation manner provided in the embodiment of the present application, the controlling the operation of the internal fan of the air conditioner includes:
and controlling an inner fan of the air conditioner to operate at a rotating speed less than a second rotating speed.
In the embodiment of the application, under the anti-cold wind state, the fan is with low rotational speed operation in the control air conditioner, and the wind speed rotational speed is too high in the prevention air conditioner, causes the heat dissipation that the electric heating device produced too fast and the not good problem of heating effect. Specifically, the fan in the air conditioner is controlled to operate at a rotating speed lower than the second rotating speed, and the second rotating speed can be less than or equal to the rotating speed of the fan in the air conditioner under the normal operation condition.
S103: and detecting whether the temperature of the inner coil is lower than a preset temperature.
In the embodiment of the application, whether the cold air prevention state exits or not can be determined by detecting the temperature of the inner coil; specifically, the detection may be performed continuously or periodically, such as once every 10 s. Wherein the preset temperature may be the temperature of the inner coil that meets the normal operating conditions of the machine, for example 30 degrees celsius. Specifically, the temperature of the inner coil may be detected by an inner coil temperature sensor disposed in the indoor unit of the air conditioner, as shown in fig. 2.
S104: and if the temperature of the inner coil is not lower than the preset temperature, the air deflector is opened, the electric heating device is controlled to stop heating, and the air conditioner is controlled to heat.
In the embodiment of the application, if the temperature of the inner coil pipe is detected to reach the preset temperature (greater than or equal to the preset temperature), the air conditioner can normally heat at the moment, cold air cannot be sent out, and the air conditioner can exit from the cold air prevention state. Specifically, the air deflector can be opened, the electric heating device is controlled to stop heating, and the air conditioner is controlled to enter a normal heating mode.
The control of the heating of the air conditioner can be realized by controlling the air conditioner outdoor unit and the air conditioner indoor unit to operate under the normal power of the heating mode.
In another possible implementation manner provided by the embodiment of the present application, controlling the outdoor unit of the air conditioner to operate at a normal power includes controlling the external fan of the air conditioner to operate at a third rotation speed and controlling the outdoor compressor of the air conditioner to operate at a second preset frequency after exiting from the cold air prevention state.
In this application embodiment, after exiting from the cold-blast protection state, control the operation of the outer fan of air conditioner with the third rotational speed, control outdoor compressor and operate with second preset frequency, wherein, the third rotational speed can be the normal rotational speed of outer fan under the heating mode, and the second preset frequency can be the normal frequency of outdoor compressor under the heating mode. Referring to the explanation of the above embodiment, if the outdoor unit of the air conditioner is in the low power operation state in the cold air prevention state, the outdoor fan of the air conditioner may be controlled to switch from the original rotation speed to the third rotation speed, and the outdoor compressor may be controlled to increase from the original frequency to the second preset frequency.
For example, in the cold wind prevention state, the outdoor compressor is operated at a frequency of 20hz, and the second preset frequency is 70hz, and after the cold wind prevention state is exited, the outdoor compressor can be controlled to rapidly increase the frequency to 70hz at a speed of 3s5 hz.
In another possible implementation manner provided by the embodiment of the present application, the third rotation speed and the second preset frequency may be determined by:
and detecting the outdoor temperature, and determining the third rotating speed and the second preset frequency according to the outdoor temperature.
In the embodiment of the present application, since the capacity of the outdoor unit of the air conditioner to absorb heat from the outdoor environment is affected by the temperature of the outdoor environment, for example, when the outdoor unit of the air conditioner operates at the same power, the heat absorption rate of the outdoor unit of the air conditioner is slower when the outdoor temperature is lower than when the outdoor temperature is higher. When the outdoor temperature is lower, the heat absorption rate of the outdoor unit of the air conditioner can be improved by properly increasing the rotating speed of the external fan of the air conditioner and the frequency of the outdoor compressor, so that the heating efficiency of the air conditioner is adapted; when the outdoor temperature is higher, the rotating speed of the external fan and the frequency of the outdoor compressor can be correspondingly reduced, and energy waste is avoided. Therefore, the corresponding relation between the outdoor temperature and the third rotating speed and the second preset frequency can be predetermined, and the rotating speed of the external fan and the frequency of the outdoor compressor can be automatically adjusted based on the corresponding relation under different outdoor temperatures, so that the heating efficiency of the air conditioner is ensured. Specifically, the outdoor temperature may be detected by an outdoor ambient temperature sensor disposed on the outdoor unit of the air conditioner.
Referring to fig. 4, a preferred flowchart of an air conditioner operation method according to an embodiment of the present disclosure is described below.
