Detailed Description
The embodiment firstly provides a control method of an air conditioner, which can monitor the temperature of an indoor heat exchanger of the air conditioner, find the high-temperature overheat condition in time, provide accurate basis for adjusting the running state of related components, and effectively ensure the working reliability of the air conditioner. Fig. 1 is a schematic view of a control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 1, the control method of the air conditioner may perform the steps of:
step S102, receiving a trigger signal for starting a heating mode of the air conditioner and controlling a compressor of the air conditioner to be started;
step S104, detecting the actual temperature of an indoor heat exchanger of the air conditioner after the compressor is started for a first preset time;
and S106, adjusting the running states of the compressor, the indoor fan of the air conditioner, the expansion valve and the air deflector according to the actual temperature.
In the above steps, step S102 receives a trigger signal for the air conditioner to start the heating mode and controls a compressor of the air conditioner to start, and specifically, the trigger signal for the air conditioner to start the heating mode may be obtained in various ways. For example, the information may be obtained through a remote controller of the air conditioner, a display device, a voice device, or a mobile terminal bound to the air conditioner. The mobile terminal may be a smart device convenient to move, such as a smart phone, a tablet computer, and the like. Receiving a trigger signal for starting a heating mode of the air conditioner means that the air conditioner starts to operate in the heating mode.
After the air conditioner starts the heating mode, the compressor is controlled to be started, and actually, the heat exchange system of the air conditioner is controlled to be started, wherein the heat exchange system comprises the compressor. In addition, the heat exchange system can also comprise components such as an indoor heat exchanger, an outdoor heat exchanger, an expansion valve and the like. The indoor heat exchanger is arranged in an indoor unit of the air conditioner, and the outdoor heat exchanger is arranged in an outdoor unit of the air conditioner. In the case where the air conditioner is operated in a heating mode, the indoor heat exchanger is used as a condenser and the outdoor heat exchanger is used as an evaporator.
Specifically, when the air conditioner operates in the heating mode, the compressor compresses the refrigerant into high-temperature and high-pressure gas, then liquefies the high-temperature and high-pressure refrigerant gas into low-temperature and high-pressure liquid through the indoor heat exchanger, at this time, the refrigerant releases a large amount of heat, at this time, the indoor temperature is increased, then the expansion valve throttles and reduces the pressure of the liquid refrigerant, the outdoor heat exchanger absorbs the heat of outdoor air, and the gas becomes isothermal and isobaric again to circulate.
Under the condition that the air conditioner runs in a heating mode, the indoor heat exchanger is easily in a high-temperature state, so that the normal running of the air conditioner is influenced, the service life of the air conditioner is possibly shortened, and the use experience of a user is influenced. Therefore, after the step S102 receives the trigger signal for the air conditioner to start the heating mode and controls the compressor of the air conditioner to be started, the step S104 may be executed to detect the actual temperature of the indoor heat exchanger of the air conditioner after the compressor is started for the first preset time period. The actual temperature of the indoor heat exchanger is monitored, the condition of high temperature overheating is found in time, an accurate basis is provided for adjusting the running state of related components, and the working reliability of the air conditioner is effectively guaranteed.
The actual temperature of the indoor heat exchanger is monitored after the compressor is started for a first preset time, because the indoor heat exchanger generally does not reach a high-temperature state in a very short time when the compressor is started, the monitoring is not needed to be performed at the beginning. In a specific embodiment, the first predetermined period of time may be 2 minutes. The actual temperature of the indoor heat exchanger is detected, specifically, a temperature sensor can be arranged at the indoor heat exchanger, so that the actual temperature of the indoor heat exchanger can be detected through the temperature sensor.
Step S106 is to adjust the operation states of the compressor and the indoor fan, the expansion valve, and the air deflector of the air conditioner according to the actual temperature, and in a specific embodiment, the frequency of the compressor, the rotation speed of the indoor fan, the opening degree of the expansion valve, and the air outlet area of the air deflector may be adjusted. More specifically, the frequency of the compressor can be reduced, the rotating speed of the indoor fan can be increased, the opening degree of the expansion valve can be increased, and the air outlet area of the air deflector can be increased. It should be noted that the compressor is disposed in an outdoor unit of the air conditioner, the indoor fan is disposed in an indoor unit of the air conditioner, the expansion valve is disposed between the indoor heat exchanger and the outdoor heat exchanger, and the air deflector is disposed at an air outlet of the indoor unit.
Under the condition that the air conditioner operates in the heating mode, the indoor fan can convey hot air subjected to heat exchange through the indoor heat exchanger to the indoor environment, and the hot air can be prevented from being gathered at the indoor heat exchanger by increasing the rotating speed of the indoor fan, so that the temperature of the indoor heat exchanger is effectively reduced. The opening degree of the expansion valve is increased, so that the flow rate of the refrigerant flowing out of the indoor heat exchanger can be increased, the heat generated at the indoor heat exchanger is reduced, and the temperature of the indoor heat exchanger can be reduced. The air outlet area of the air deflector is increased, hot air can be prevented from being gathered at the indoor heat exchanger, the temperature of the indoor heat exchanger is effectively reduced, hot air can be promoted to fully circulate in the indoor environment, the temperature distribution of the indoor environment is uniform, a large amount of hot air is prevented from entering the indoor heat exchanger through the air inlet, and the temperature of the indoor heat exchanger is further guaranteed not to be too high. And through reducing the frequency of compressor, can reduce the high-temperature high-pressure gas and get into indoor heat exchanger to reduce the heat that indoor heat exchanger department refrigerant released to a certain extent, and then also can reduce the temperature of indoor heat exchanger.
According to the control method of the air conditioner, the triggering signal of the air conditioner for starting the heating mode is received, the compressor of the air conditioner is controlled to be started, the actual temperature of the indoor heat exchanger of the air conditioner is detected after the compressor is started for the first preset time, the running states of the compressor, the indoor fan, the expansion valve and the air deflector of the air conditioner are adjusted according to the actual temperature, the temperature of the indoor heat exchanger of the air conditioner can be monitored, the high-temperature overheating condition can be found in time, an accurate basis is provided for adjusting the running states of relevant components, and the working reliability of the air conditioner is effectively guaranteed.
In some optional embodiments, the air conditioner may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the control method of the air conditioner of this embodiment in combination with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of a part of steps may be modified according to specific implementation requirements. Fig. 2 is a detailed flowchart of a control method of an air conditioner according to an embodiment of the present invention, which may include the steps of:
step S202, receiving a trigger signal for starting a heating mode of the air conditioner and controlling a compressor of the air conditioner to be started;
step S204, detecting the actual temperature of an indoor heat exchanger of the air conditioner after the compressor is started for a first preset time;
step S206, judging whether the actual temperature is greater than or equal to a first preset temperature, if so, executing step S210, and if not, executing step S208;
step S208, controlling the compressor to keep the initial frequency, the indoor fan to keep the initial rotating speed, the expansion valve to keep the initial opening degree, and the air deflector to keep the initial air outlet area;
step S210, controlling the frequency of the compressor to be reduced, the rotating speed of the indoor fan to be increased, the opening degree of the expansion valve to be increased, and keeping the initial air outlet area of the air deflector for a second preset time;
step S212, determining whether the actual temperature is increased to be greater than or equal to a second predetermined temperature, if yes, performing step S216, and if not, performing step S214;
step S214, controlling the compressor to keep the current frequency, the indoor fan to keep the current rotating speed, the expansion valve to keep the current opening degree, and the air deflector to keep the current air outlet area;
step S216, controlling the frequency of the compressor to be reduced, the rotating speed of the indoor fan to be increased, the opening degree of the expansion valve to be increased, and the air outlet area of the air deflector to be increased for a second preset time;
step S218, determining whether the actual temperature is increased to be greater than or equal to a third preset temperature, if so, performing step S220, and if not, performing step S214;
step S220, controlling the compressor to stop for more than or equal to a third preset time, keeping the current rotating speed of the indoor fan, keeping the current opening degree of the expansion valve and keeping the current air outlet area of the air deflector;
step S222, determining whether the actual temperature is lower than a fourth preset temperature, if so, executing step S224, and if not, executing step S220;
step S224, the compressor is controlled to recover the initial frequency.
In the above steps, step S202 and step S204 are executed first, the trigger signal for starting the heating mode of the air conditioner is received, the compressor of the air conditioner is controlled to be started, the actual temperature of the indoor heat exchanger of the air conditioner is detected after the compressor is started for the first preset time period, and then the operating states of the compressor, the indoor fan, the expansion valve and the air deflector are adjusted step by step according to the actual temperature of the indoor heat exchanger.
Specifically, step S206 determines whether the actual temperature is greater than or equal to a first preset temperature, and if the determination result of step S206 is negative, that is, the actual temperature is less than the first preset temperature, step S208 is executed to control the compressor to maintain the initial frequency, control the indoor fan to maintain the initial rotation speed, control the expansion valve to maintain the initial opening, and control the air deflector to maintain the initial air outlet area. The actual temperature is lower than the first preset temperature, which indicates that the temperature of the indoor heat exchanger is lower at this moment, and the indoor heat exchanger is not in a high-temperature state, and the compressor, the indoor fan, the expansion valve and the air deflector are not required to be adjusted, so that the compressor is controlled to keep the initial frequency, the indoor fan keeps the initial rotating speed, the expansion valve keeps the initial opening degree, and the air deflector keeps the initial air outlet area. In one particular embodiment, the first predetermined temperature may be 58 ℃.
If the determination result in the step S206 is yes, that is, if the actual temperature is greater than or equal to the first preset temperature, the step S210 is executed, the frequency of the compressor is controlled to decrease, the rotation speed of the indoor fan is increased, the opening degree of the expansion valve is increased, and the air deflector maintains the initial air outlet area for a second preset time. The actual temperature is larger than or equal to the first preset temperature, which shows that the temperature of the indoor heat exchanger is higher at the moment, and normal operation of the air conditioner can be possibly influenced without intervention, so that the frequency of the compressor can be controlled to be reduced, the rotating speed of the indoor fan is increased, the opening of the expansion valve is increased, the air deflector keeps the initial air outlet area and lasts for the second preset time, and the indoor heat exchanger is prevented from being continuously heated to a large extent by adjusting the frequency of the compressor, the rotating speed of the indoor fan and the opening of the expansion valve.
The process of adjusting the compressor frequency, the indoor fan speed, and the expansion valve opening may last for a second predetermined duration. In a specific embodiment, the second preset time period may be 10 minutes. For example, if the initial frequency of the compressor is a and the reduced frequency per minute is B, then within a second preset time period of reducing the frequency of the compressor by 10 minutes, the frequency per minute of the compressor may be: A-B, A-2B, A-3B, A-4B … …. The initial rotational speed of indoor fan is C, and the rotational speed that every minute rises is D, and in the second of indoor fan rotational speed of rising was predetermine for 10 minutes then, the rotational speed of the indoor fan of minute can be in proper order: c + D, C +2D, C +3D, C +4D … …. The initial opening degree of the expansion valve is E, and the opening degree increased per minute is F, so that within a second preset time period of increasing the opening degree of the expansion valve by 10 minutes, the opening degrees of the expansion valve per minute may be: e + F, E +2F, E +3F, E +4F … …. In the adjusting process, the air deflector keeps the initial air outlet area unchanged.
After the second preset duration is adjusted for the compressor, the indoor fan and the expansion valve through the step S210, the step S212 may be executed to determine whether the actual temperature is increased to be greater than or equal to the second preset temperature, and if the determination result of the step S212 is negative, that is, the actual temperature is less than the second preset temperature, the step S214 is executed to control the compressor to maintain the current frequency, the indoor fan to maintain the current rotation speed, the expansion valve to maintain the current opening degree, and the air deflector to maintain the current air outlet area. The actual temperature is lower than the second preset temperature, which indicates that after the compressor, the indoor fan and the expansion valve are adjusted, the indoor heat exchanger is still at the increased temperature but is not increased to the second preset temperature, at this time, the compressor, the indoor fan and the expansion valve do not need to be further adjusted, and the air deflector does not need to be adjusted, so that the compressor is controlled to keep the current frequency, the indoor fan keeps the current rotating speed, the expansion valve keeps the current opening degree, and the air deflector keeps the current air outlet area. The second predetermined temperature is greater than the first predetermined temperature and in one particular embodiment, the second predetermined temperature may be 62 ℃.
If the determination result in the step S212 is yes, that is, if the actual temperature is greater than or equal to the second preset temperature, the step S216 is executed to control the frequency of the compressor to decrease, the rotation speed of the indoor fan to increase, the opening degree of the expansion valve to increase, and the air outlet area of the air deflector to increase for the second preset time. The actual temperature is greater than or equal to the second preset temperature, which indicates that after the compressor, the indoor fan and the expansion valve are adjusted, the indoor heat exchanger is still continuously raised to the second preset temperature, and the indoor heat exchanger is in a high-temperature state at the moment, so that the frequency of the compressor can be controlled to be reduced, the rotating speed of the indoor fan is raised, the opening degree of the expansion valve is increased, and the air outlet area of the air deflector is increased and is continuously maintained for the second preset time. The indoor heat exchanger is further prevented from being continuously heated to a large extent by continuously adjusting the frequency of the compressor, the rotating speed of the indoor fan and the opening degree of the expansion valve and adjusting the air outlet area of the air deflector.
The process of further adjusting the frequency of the compressor, the rotating speed of the indoor fan, the opening degree of the expansion valve and adjusting the air outlet area of the air deflector can also last for a second preset time. For example, the second preset time period may be 10 minutes, the frequency of the compressor after the second preset time period of the previous frequency reduction is a-10B, and the frequency of the compressor per minute reduction this time may also be B, so that within the second preset time period of the compressor frequency reduction this time of 10 minutes, the frequency of the compressor per minute may be: A-11B, A-12B, A-13B, A-14B … …. The rotational speed that indoor fan rose the rotational speed second before after presetting for a long time is C +10D, and this minute rotational speed that rises still can be D, so in this time rose indoor fan rotational speed's second is preset for a long time 10 minutes, the rotational speed of minute indoor fan can be in proper order: c +11D, C +12D, C +13D, C +14D … ….
The opening degree of the expansion valve after the second preset time length of the opening degree is increased for the last time is E +10F, the increasing speed per minute can also be F, and the opening degree of the expansion valve per minute can be sequentially within the second preset time length of 10 minutes of the opening degree of the expansion valve per minute: e +11F, E +12F, E +13F, E +14F … …. In the adjusting process, the air outlet area of the air deflector is also adjusted. The initial air-out area of aviation baffle is G, and the air-out area that the per minute increases is H, and then in the second of increase aviation baffle air-out area is predetermine for a long time 10 minutes, the air-out area of per minute aviation baffle can be in proper order: g + H, G +2H, G +3H, G +4H … ….
In the above embodiments, the frequency, the rotating speed and the opening degree of the two adjustments of the compressor frequency, the rotating speed of the indoor fan and the opening degree of the expansion valve are the same, that is, in the two adjustments, the frequency of the reduction of the compressor per minute is the same, the rotating speed of the increase of the indoor fan per minute is the same, and the opening degree of the increase of the expansion valve per minute is the same. In other embodiments, the frequency, speed, and magnitude of the two adjustments to the compressor frequency, indoor fan speed, and expansion valve opening may be different.
For example, the frequency of decrease per minute of the compressor, the rotational speed of increase per minute of the indoor fan, and the opening degree of increase per minute of the expansion valve may be increased in the latter adjustment as compared to the former adjustment. That is, the previous adjustment of the compressor frequency, the indoor fan speed, and the expansion valve opening may be relatively slow. The later adjustment of the frequency of the compressor, the rotating speed of the indoor fan and the opening degree of the expansion valve can be faster. Adjust the actual conditions who accords with indoor heat exchanger more step by step like this, effectively avoid indoor heat exchanger high temperature.
After the compressor, the indoor fan and the expansion valve are further adjusted in the step S216, and the air outlet area of the air deflector is adjusted for the second preset time, the step S218 may be executed to determine whether the actual temperature rises to be greater than or equal to a third preset temperature, and if the determination result in the step S218 is negative, that is, the actual temperature is less than the third preset temperature, the step S214 is executed to control the compressor to maintain the current frequency, the indoor fan to maintain the current rotation speed, the expansion valve to maintain the current opening degree, and the air deflector to maintain the current air outlet area. The actual temperature is lower than the third preset temperature, which indicates that after the compressor, the indoor fan and the expansion valve are further adjusted and the air outlet area of the air deflector is adjusted for the second preset duration, the indoor heat exchanger is still at the increased temperature but is not increased to the third preset temperature, and at this moment, the compressor, the indoor fan, the expansion valve and the air deflector do not need to be further adjusted, so that the compressor is controlled to keep the current frequency, the indoor fan keeps the current rotating speed, the expansion valve keeps the current opening degree, and the air deflector keeps the current air outlet area. The third predetermined temperature is greater than the second predetermined temperature and in one particular embodiment, the third predetermined temperature may be 65 ℃.
In both cases, the current frequency, the current rotation speed, the current opening degree, and the current air outlet area in step S214 are different, although step S214 may be executed if the determination results in step S212 and step S218 are negative. And step S214 is executed if the judgment result in the step S212 is negative, the current frequency is the frequency after the compressor reduces for the first time for the second preset time, the current rotating speed is the rotating speed after the indoor fan increases for the first time for the second preset time, the current opening degree is the opening degree after the expansion valve increases for the first time for the second preset time, and the current air outlet area is the initial air outlet area of the air deflector which is not adjusted.
And if the judgment result in the step S218 is no, executing the step S214, where the current frequency is the frequency after the compressor further decreases for the second preset time, the current rotating speed is the rotating speed after the indoor fan further increases for the second preset time, the current opening degree is the opening degree after the expansion valve further increases for the second preset time, and the current air outlet area is the air outlet area after the air deflector increases for the second preset time.
If the determination result in the step S218 is yes, that is, if the actual temperature is greater than or equal to the third preset temperature, step S220 is executed, the compressor is controlled to stop for a time period greater than or equal to the third preset time period, the indoor fan keeps the current rotating speed, the expansion valve keeps the current opening degree, and the air deflector keeps the current air outlet area. The actual temperature is greater than or equal to the third preset temperature, which indicates that after the compressor, the indoor fan and the expansion valve are further adjusted and the air outlet area of the air deflector is adjusted for the second preset time, the temperature of the indoor heat exchanger is continuously increased and is increased to the third preset temperature, and at the moment, the indoor heat exchanger is in a high-temperature state and is very urgent, so that the compressor can be controlled to stop for the third preset time or more, the indoor fan keeps the current rotating speed, the expansion valve keeps the current opening degree, and the air deflector keeps the current air outlet area.
The mode of controlling the compressor to stop can directly and effectively prevent the indoor heat exchanger from continuously and greatly heating. In this case, the indoor fan maintains the current rotation speed, which is the rotation speed after the indoor fan is further increased for the second preset time. The expansion valve maintains the current opening degree, which means the opening degree of the expansion valve after further increasing for a second preset time period. And keeping the current air outlet area by the air deflector, namely increasing the air outlet area of the air deflector after a second preset time.
And controlling the compressor to stop for a time period greater than or equal to a third preset time period, in fact, after the compressor stops for the third preset time period, executing step S222 to determine whether the actual temperature is less than a fourth preset temperature, and executing step S224 to control the compressor to recover the initial frequency if the determination result of step S222 is yes, that is, the actual temperature is less than the fourth preset temperature. If the determination result in the step S222 is negative, that is, the actual temperature is greater than or equal to the fourth preset temperature, step S220 is executed to continue to control the compressor to stop, where the stop time duration is greater than the third preset time duration. In a specific embodiment, the third predetermined time period may be 3 minutes and the fourth predetermined temperature may be 50 ℃.
That is, the compressor is controlled to stop for a time period greater than or equal to the third preset time period, an upper limit is not set, the compressor is stopped until the actual temperature of the indoor heat exchanger is lower than the fourth preset temperature, and at this time, the compressor is controlled to recover the initial frequency. According to the embodiment, the initial frequency of the compressor is a, after the compressor is controlled to stop for a time period greater than or equal to a third preset time period, if the actual temperature is lower than a fourth preset temperature, it is indicated that the compressor is stopped to well perform an effect of cooling an indoor heat exchanger, and at this time, the compressor can be controlled to recover the initial frequency a.
In addition, after the compressor is controlled to recover the initial frequency in step S224, if the actual temperature is lower than the fifth preset temperature 52, the frequency of the compressor may be controlled to rapidly increase according to the second frequency. In a specific embodiment, the fifth predetermined temperature may be 52 ℃. That is, after the compressor is controlled to recover the initial frequency, the temperature of the indoor heat exchanger generally starts to rise, but even after the temperature of the indoor heat exchanger rises, the temperature is smaller than the fifth preset temperature, which indicates that the temperature of the indoor heat exchanger does not rise greatly, the frequency of the compressor can be quickly increased, and the heating capacity and the heating effect of the air conditioner are improved.
After controlling the frequency of the compressor to rapidly increase according to the second frequency, if the actual temperature is less than the sixth preset temperature 54, the frequency of the compressor may be controlled to slowly increase according to the first frequency. Wherein the second frequency may be greater than the first frequency. And the fourth preset temperature, the fifth preset temperature and the sixth preset temperature are sequentially increased and are all smaller than the first preset temperature. In a specific embodiment, the sixth predetermined temperature may be 54 ℃.
It should be noted that the specific values of the preset values are only exemplary, and are not meant to limit the present invention. In other embodiments, other values may be set according to actual conditions. However, the magnitude relationship among the preset values is required to meet the requirement, for example, the fourth preset temperature, the fifth preset temperature and the sixth preset temperature are sequentially increased and are all smaller than the first preset temperature.
After the frequency of the compressor is controlled to rapidly rise according to the second frequency, the temperature of the indoor heat exchanger is still lower than the sixth preset temperature although the temperature of the indoor heat exchanger continues to rise, which indicates that the temperature of the indoor heat exchanger is not too high at this moment, but in order to avoid being in a high-temperature state, the frequency of the compressor can be controlled to slowly rise according to the first frequency, and the temperature rise amplitude of the indoor heat exchanger is reduced.
After the frequency of the compressor is increased and adjusted, if the actual temperature of the indoor heat exchanger is greater than or equal to the sixth preset temperature, whether the actual temperature is greater than or equal to the first preset temperature or not can be judged again, and corresponding adjustment is performed by referring to the previous steps. In addition, after the frequency of the compressor, the rotation speed of the indoor fan, the opening degree of the expansion valve, and the air outlet area of the air deflector are adjusted in steps S208 and S214, it may be determined again whether the actual temperature is greater than or equal to the first preset temperature, and corresponding adjustment may be performed according to the determination result.
In the control method of the air conditioner in the embodiment, when the actual temperature of the indoor heat exchanger is greater than or equal to the first preset temperature, the frequency of the compressor is controlled to be reduced, the rotating speed of the indoor fan is increased, the opening degree of the expansion valve is increased, and the air deflector keeps the initial air outlet area and lasts for a second preset time; if the actual temperature still rises to be more than or equal to a second preset temperature, controlling the frequency of the compressor to be reduced, the rotating speed of the indoor fan to rise, the opening degree of the expansion valve to be increased, and the air outlet area of the air deflector to be increased for a second preset time; if the actual temperature still rises to be more than or equal to the third preset temperature, the compressor is controlled to stop for more than or equal to the third preset time, the indoor fan keeps the current rotating speed, the expansion valve keeps the current opening degree, the air deflector keeps the current air outlet area, the running states of the compressor, the indoor fan, the expansion valve and the air deflector are gradually adjusted, the problem of parts caused by the fact that the adjusting mode is too violent is avoided, the indoor heat exchanger is cooled and protected, the heating effect of the air conditioner is guaranteed while the working reliability of the air conditioner is improved, and the comfort level experience of users is improved.
