Detailed Description
In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below.
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 other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.
At present, when the heating mode of the air conditioner is started in a low-temperature environment, cold air is sent out by the air conditioner in a period of time, and uncomfortable experience is brought to a user.
In order to solve the problems, the application provides an air conditioner operation method and system, which can prevent cold air from being sent out during the hot start of an air conditioner by closing an air deflector, achieve the effect of cold air prevention, control an electric heater to start electric heating, quickly improve the temperature of a coil pipe in the air conditioner by utilizing heat generated by the electric heater, solve the problem that the air conditioner sends out cold air during the start at low temperature, and avoid uncomfortable experience for a user.
For easy understanding, the following describes in detail an air conditioner operation method and system provided in the embodiments of the present application with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of an air conditioner operation method according to an embodiment of the present application is shown, where the method may include the following steps:
s101: 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 heated and started, the air conditioner enters a cold air prevention state; the cold air prevention state can prevent cold air from being sent out when the air conditioner is started 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 smaller 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 environment 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 disposed in the indoor unit of the air conditioner, and is capable of detecting an indoor environment temperature.
S102: and in the cold air prevention state, keeping an 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 heat generated by the electric heating device is used for increasing the temperature of an inner coil pipe of the air conditioner.
In the embodiment of the application, the air deflector of the air conditioner is kept to be closed in a cold air prevention state. The air conditioner air deflector is an air guiding device arranged on an air conditioner indoor unit, and mainly aims to assist in adjusting the wind direction of an air conditioner and avoid uncomfortable experience of direct blowing of the air conditioner to a user. If the air conditioner air deflector is in an open state during starting, closing the air conditioner air deflector 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 performed 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 application is shown; as shown in fig. 2 and 3, the air deflector is positioned at the outer side of the indoor unit of the air conditioner, and cold air of the air conditioner is not fed into the room under the condition that the air deflector is not opened, so that the cold air is prevented from being fed out when the air conditioner is started up at a hot state.
In the related art, some air conditioner configurations mainly implement a cold air prevention function by only operating an air conditioner outdoor unit, and this implementation has the following drawbacks: when the indoor and outdoor environment temperature is low, the cold air prevention time is long, the waiting time is long after the machine is started, and the user experience is poor.
As shown in fig. 2 and 3, the electric heating device is located in the indoor unit of the air conditioner, and the electric heating device mainly plays a role of auxiliary heating. In some possible implementations, the electric heating device may be annularly arranged in the air conditioning indoor unit; the air conditioner inner coil pipe can be arranged near the electric heating device, and exchanges heat with air outside the air pipe when chilled water or hot water flows through the air conditioner inner coil pipe, so that the effect of adjusting the indoor air temperature is achieved. In some possible implementations, the air conditioning inner coil is close to the supply air port of the air conditioning indoor unit, so that the inner coil temperature is close to the supply air temperature of the air conditioning indoor unit. The heat generated by the electric heating device can quickly increase the temperature of the coil pipe in the air conditioner, solve the problem that cold air is sent out when the air conditioner is started at low temperature, shorten the cold air prevention time and improve the user experience.
At present, the cold air prevention function of some air conditioner configurations is mainly realized by only operating the air conditioner outdoor unit, and the air conditioner indoor unit is not started until the temperature of the inner coil reaches above the starting temperature (for example, 30 ℃). The realization method independently operates the air conditioner indoor unit under the condition of closing the air conditioner 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 at high frequency for a long time and the air conditioner indoor unit is not started, so that the phenomenon of over-high pressure or over-current of an air conditioner system is easily caused, the air conditioner is stopped, and even the problems of shortened service life of the machine, safety risk and the like are possibly caused.
In one possible implementation manner provided by the embodiment of the application, in the cold air prevention state, the air conditioner outdoor unit can be controlled to be in a stop operation state, and the coil pipe in the air conditioner can be heated only by the electric heating device.
In another possible implementation manner provided in the embodiments of the present application, after entering the cold air preventing state, the following steps may be performed:
after entering the cold air prevention state for a preset time, if the temperature of the inner coil is detected to be smaller than the preset temperature, controlling an outer fan of the air conditioner to operate at a rotating speed smaller than a first rotating speed, and controlling an outer compressor of the air conditioner to operate at a frequency smaller 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 provides a heat dissipation function for a condenser of the air conditioner, and the heat exchange efficiency of the condenser can be improved; the outdoor compressor plays a role of compressing and driving the refrigerant. After entering the cold air prevention state for a preset period of time, for example, after entering the cold air prevention state for 2 minutes, if the temperature of the inner coil is detected to be still lower than the preset temperature (for example, 30 ℃), the low-power operation of the air conditioner outdoor unit can be controlled, and the temperature rise of the inner coil is assisted.
The outer fan of the air conditioner can be controlled to run at a low rotation speed, and particularly can run at a rotation speed smaller than a first rotation speed, wherein the first rotation speed can be smaller than or equal to the rotation speed of the normal running outer fan; the control of the low frequency operation of the outdoor compressor of the air conditioner may specifically be performed at a frequency less than a first preset frequency, which may be less than or equal to a normal operating frequency of the outdoor compressor. For example, if the normal operating frequency of the outdoor compressor is 70hz, the outdoor compressor is operated at a frequency of 20hz in a cold air preventing state. On the one hand, the air conditioning outdoor unit can absorb heat from the outdoor environment and assist the temperature rise of the inner coil; on the other hand, the air conditioner outdoor unit operates under low power, so that risk hidden dangers such as over-high pressure, over-current and the like caused by the operation of the air conditioner outdoor unit can be avoided.
In another possible implementation manner provided by the embodiments of the present application, the first rotation speed and the first preset frequency may be predetermined according to the following method: and detecting an outdoor temperature, and determining the first rotating speed and the first preset frequency according to the outdoor temperature.
In this 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 outdoor environment temperature, for example, when the outdoor unit is operated under 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 air conditioner outdoor unit can be improved by properly improving the rotating speed of the air conditioner external fan and the frequency of the outdoor compressor, so that the temperature rise time of the temperature of the internal coil is further shortened; and when the outdoor temperature is higher, the rotating speed of the external fan and the frequency of the outdoor compressor can be correspondingly reduced, so that the waste of energy sources 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 limit of 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 internal coil pipe is ensured on the premise of avoiding over-high pressure and over-current caused by the operation of the air conditioner outdoor unit. Specifically, the outdoor temperature may be detected according to an outdoor ambient temperature sensor disposed on the air conditioner outdoor unit.
The related art described above also has the following problems: the indoor unit is not opened during cold air prevention, so that the heat exchanger outside the air conditioner cannot fully utilize the heat, more heat is lost during heat exchange, and the energy utilization rate is low.
In another possible implementation manner provided in the embodiments of the present application, the following steps may be performed in the cold air preventing state:
and in the cold air prevention state, controlling an inner fan of the air conditioner to run, wherein the inner fan is positioned in an indoor unit of the air conditioner, and the inner fan is used for enabling heat generated by the electric heating device to circulate in the indoor unit of the air conditioner.
In this application embodiment, at cold wind prevention state, can also control the interior fan operation of air conditioner, the interior fan of air conditioner mainly plays the effect of heat exchange. The inner blower is located in the indoor unit of the air conditioner, and specific deployment positions can be referred to fig. 2 and 3. On one hand, the operation of the inner fan can promote the heat circulation in the air conditioner indoor unit, prevent the heat generated by the electric heating device from concentrating in a certain area to cause the overall temperature rise of the inner coil to be slower, ensure that the heat is distributed as uniformly as possible, reduce the heat loss and improve the utilization rate of the heat generated by the electric heating device; on the other hand, compared with the implementation mode of the prior art introduced above, if the air conditioner outdoor unit is started in the cold air prevention state, the pressure of the air conditioner system can be balanced through the operation of the inner fan, the risk of over-high pressure and over-current caused by only starting the air conditioner outdoor unit is avoided, the full utilization of heat of the heat exchanger can be promoted, and the loss of heat is reduced; the heat exchanger of the air conditioner can recover heat from the air, and plays a role in reducing heat loss in the operation of the air conditioner.
In one possible implementation manner, the fan in the air conditioner is controlled to operate first in the cold air prevention state, and the air conditioner outdoor unit is controlled to operate after entering the cold air prevention state for a period of time, so that the problems of over-high pressure, over-current and the like caused by firstly starting the air conditioner outdoor unit and then starting the air conditioner indoor unit can be prevented.
In another possible implementation manner provided in the embodiments of the present application, the controlling the operation of the inner fan of the air conditioner includes:
and controlling the inner fan of the air conditioner to operate at a rotating speed smaller than the second rotating speed.
In this application embodiment, prevent under the cold wind state, fan operation with low rotational speed in the control air conditioner prevents that wind speed rotational speed is too high in the air conditioner, causes the heat dissipation that electric heater spare produced too fast and the not good problem of heating effect. Specifically, the fan in the air conditioner is controlled to run at a rotation speed smaller than a second rotation speed, and the second rotation speed can be smaller than or equal to the rotation speed of the fan in the air conditioner under normal running.
S103: and detecting whether the temperature of the inner coil pipe is smaller than a preset temperature.
In the embodiment of the application, whether the cold air prevention state is exited or not can be determined by detecting the temperature of the inner coil; in particular, the detection may be continuous or periodic, such as one time at 10s intervals. The preset temperature may be an inner coil temperature that satisfies normal machine operating conditions, such as 30 degrees celsius. Specifically, the temperature of the inner coil may be detected from an inner coil temperature sensor disposed in the air conditioning indoor unit, as shown with reference to fig. 2.
S104: if the temperature of the inner coil pipe is detected to be not less 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 this embodiment of the present application, if the temperature of the inner coil is detected to reach the preset temperature (greater than or equal to the preset temperature), it is indicated that the air conditioner can normally heat at this time, and cold air is not sent out, so that the cold air prevention state can be exited. 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 air conditioning heat can be realized by controlling the air conditioning outdoor unit and the air conditioning indoor unit to operate under the normal power of a 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 under normal power includes, after exiting the cold air preventing state, controlling the external fan of the air conditioner to operate at a third rotational speed, and controlling the outdoor compressor of the air conditioner to operate at a second preset frequency.
In this embodiment, after exiting the cold air prevention state, the air conditioner external fan is controlled to run at a third rotation speed, and the outdoor compressor is controlled to run at a second preset frequency, wherein the third rotation speed can be a normal rotation speed of the external fan in a heating mode, and the second preset frequency can be a normal frequency of the outdoor compressor in the heating mode. Referring to the description in 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 unit 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 air prevention state, the outdoor compressor is operated at a frequency of 20hz, and the second preset frequency is 70hz, and after the cold air prevention state is exited, the outdoor compressor can be controlled to be rapidly increased to 70hz at a speed of 3s5 hz.
In another possible implementation manner provided in the embodiment of the present application, the third rotation speed and the second preset frequency may be determined in the following manner:
detecting an outdoor temperature, and determining the third rotating speed and the second preset frequency according to the outdoor temperature.
In this 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 outdoor environment temperature, for example, when the outdoor unit is operated under 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 improving the rotating speed of the external fan and the frequency of the outdoor compressor of the air conditioner, so that the method is suitable for the heating efficiency of the air conditioner; and when the outdoor temperature is higher, the rotating speed of the external fan and the frequency of the outdoor compressor can be correspondingly reduced, so that energy waste is avoided. Therefore, the corresponding relation between the outdoor temperature and the second preset frequency and the corresponding relation between the third rotating speed and the second preset frequency can be preset, and the rotating speed of the external fan and the frequency of the external 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 according to an outdoor ambient temperature sensor disposed on the air conditioner outdoor unit.
