Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A control method of an air conditioner according to an embodiment of the present invention, which may be employed by the air conditioner, is described below with reference to fig. 1.
Referring to fig. 1, a control method of an air conditioner according to an embodiment of the present invention may mainly include the steps of:
s1, starting a fresh air function, and acquiring local time;
s2, judging whether the local time is day or night;
s3, judging the current working mode according to the local time, wherein the working mode comprises: a daytime cooling/dehumidifying mode, a daytime air supply mode, a nighttime cooling/dehumidifying mode and a nighttime air supply mode;
s4, judging the relation between the current outdoor temperature and the preset outdoor temperature value according to the current working mode;
and S5, controlling the compressor to work according to a preset mode and the fresh air fan to work according to the relation between the current outdoor temperature and a preset outdoor temperature value.
As shown in the combined figure 1, when the air conditioner works normally, the indoor carbon dioxide concentration is gradually increased, the air conditioner is required to start the fresh air function, the air conditioner with the fresh air function can introduce outdoor fresh air into the room, so that the indoor oxygen concentration is increased, and the indoor carbon dioxide concentration is reduced. Further, after the air conditioner starts the fresh air function, the air conditioner starts to acquire local time, and judges whether the local time is in the daytime or at night, after the local time is judged, the current working mode is judged according to the local time, if the local time is in the daytime, the working mode can be a daytime cooling/dehumidifying mode or a daytime air supply mode, if the local time is at night, the working mode can be a night cooling/dehumidifying mode and a night air supply mode, and the current working mode can be adjusted and controlled according to the requirements of indoor users.
Referring to fig. 1, the relationship between the current outdoor temperature and the preset outdoor temperature value is determined according to the current working mode, and the compressor is controlled to work in the preset mode and the fresh air fan works in the preset mode according to the relationship between the current outdoor temperature and the preset outdoor temperature value. Specifically, because of the effect of the compressor of the air conditioner, there is certain difference in indoor temperature and outdoor temperature, after the new trend gets into indoorly, will influence indoor temperature to a certain extent, and influence user's use experience, therefore, predetermine outdoor temperature value through setting for, compare current outdoor temperature and predetermine outdoor temperature value, if current outdoor temperature is greater than predetermine outdoor temperature value, the air conditioner control compressor works according to a preset mode, and control new trend fan works according to a mode, if current outdoor temperature is less than predetermine outdoor temperature value, the air conditioner control compressor works according to another kind of preset mode, and control new trend fan works according to another kind of preset mode.
So set up, can make new trend fan and compressor carry out corresponding adjustment according to the concrete value of current outdoor temperature on the one hand, not only can reduce the new trend and get into indoor to the influence of indoor temperature, but also can reduce the new trend and get into indoor noise, and on the other hand air conditioner can avoid the waste of unnecessary electric quantity under the prerequisite that satisfies user's demand, can reduce the energy consumption of air conditioner.
From this, according to local time, judge the current mode of operation of air conditioner to control the compressor according to the outdoor temperature under the current mode of operation and the contrast of predetermineeing outdoor temperature and work according to the mode of predetermineeing, the new trend fan is according to the mode of predetermineeing work, not only can reduce the new trend like this and get into indoor to the influence of indoor temperature, but also can the noise reduction, and reduce the energy consumption of air conditioner, thereby can promote user's use and experience.
As shown in fig. 1, in step S2, if the local time is 8: 00-20: 00, judging that the local time is in the daytime, and if the local time is 20: 00-8: 00, the local time is determined to be at night. Specifically, according to the living habits of the user, the user is generally working and living normally when the local time is from eight am to eight pm, and at this time, it is determined that the local time is day, and the user is generally sleeping at rest when the local time is from eight pm to eight am, and at this time, it is determined that the local time is night, which not only makes step S2 more accurate, but also increases the generality of step S2, i.e., the time of day and night is different for each place, and the method of determining whether the local time is day or night in step S2 is not completely accurate, but is theoretically limited according to the approximate average time of day and night for each place.
As shown in fig. 1, in step S4, the preset outdoor temperature value T satisfies the following relation: t is more than or equal to 26 ℃ and less than or equal to 30 ℃. Specifically, when the air conditioner normally works, the working mode is the daytime cooling/dehumidifying mode, the daytime air supply mode, the night cooling/dehumidifying mode or the night air supply mode, and since none of the working modes heats the indoor space, the outdoor temperature is not too low, the preset outdoor temperature value T is set between 26 ℃ and 30 ℃, and the current outdoor temperature is adjacent to the preset outdoor temperature value or is in the range of the preset outdoor temperature value, so that when the current outdoor temperature changes in a small range, the change of the current outdoor temperature relative to the preset outdoor temperature value T is easy to occur, that is, the current outdoor temperature may change from being greater than the preset outdoor temperature value T to being smaller than the preset outdoor temperature value T, so that the compressor and the fresh air fan are adjusted correspondingly.
As shown in fig. 1, in step S5, the preset outdoor temperature value T satisfies the relation: t is 28 ℃, so set up, can make and predetermine outdoor temperature value T more reasonable, not only can prevent to predetermine outdoor temperature value T too big, all is greater than current outdoor temperature under most circumstances, but also can prevent to predetermine outdoor temperature value T undersize, all is less than current outdoor temperature under most circumstances, causes the control method of air conditioner can' T carry out more reasonable control to the compressor of air conditioner and new trend fan.
In some embodiments of the present invention, referring to fig. 1, in step S5, if the current mode is the daytime cooling/dehumidifying mode and the current outdoor temperature is lower than the preset outdoor temperature value, the frequency of the compressor is reduced, and the fresh air fan operates at the maximum air volume. Specifically, be the refrigeration/dehumidification mode daytime at current mode to when current outdoor temperature is less than preset outdoor temperature value, the compressor under the current mode is being cooled down the processing indoor, and current outdoor temperature is lower relatively, when new trend fan introduces the new trend, can not influence indoor temperature because the new trend temperature is higher, and the new trend can play certain reduction indoor temperature's effect even.
So set up, the air conditioner can control the compressor and reduce the refrigeration frequency to control new trend fan according to the operation of the biggest amount of wind, under the unchangeable prerequisite of assurance indoor temperature, the pressure of refrigerating of some compressors can be shared to new trend fan, thereby not only can promote the increase efficiency of new trend fan to indoor oxygen, but also can reduce the operating frequency of air conditioner.
In other embodiments of the present invention, referring to fig. 1, in step S5, if the current mode is the daytime cooling/dehumidifying mode and the current outdoor temperature is greater than the preset outdoor temperature value, the frequency of the compressor is increased, and the fresh air fan operates at the minimum air volume. Specifically, when the current mode is a daytime refrigeration/dehumidification mode and the current outdoor temperature is greater than a preset outdoor temperature value, the compressor in the current mode is cooling the indoor space, the current outdoor temperature is relatively high, and when the fresh air fan introduces outdoor fresh air, the fresh air can raise the indoor temperature.

Furthermore, the fresh air fan operates according to the minimum air volume, so that the influence of fresh air with high temperature on the indoor temperature can be reduced as far as possible on the premise of ensuring that the fresh air fan introduces fresh air and increasing the indoor oxygen concentration, the amplitude of frequency increase of the compressor can be reduced as far as possible, the air conditioner can be prevented from being large in energy consumption, and the reliability and the intelligence of the control method of the air conditioner can be further improved.
It should be noted that when the current outdoor temperature is equal to the preset outdoor temperature value, the compressor of the air conditioner will operate at the preset frequency, the fresh air fan will operate at the preset air volume, when the current outdoor temperature is greater than the preset outdoor temperature value, the frequency of the compressor of the air conditioner will be greater than the preset frequency, the air volume of the fresh air fan will be less than the preset air volume, when the current outdoor temperature is less than the preset outdoor temperature value, the frequency of the compressor of the air conditioner will be less than the preset frequency, and the air volume of the fresh air fan will be greater than the preset air volume.
In an embodiment of the present invention, referring to fig. 1, in step S5, if the current mode is the daytime air supply mode and the current outdoor temperature is lower than the preset outdoor temperature value, the compressor is stopped and the fresh air fan is operated at the preset air speed. Specifically, under the current mode is air supply mode daytime to when current outdoor temperature is less than preset outdoor temperature value, because current outdoor temperature is lower relatively, when new trend fan introduces new trend to indoor, the lower new trend of temperature moves according to presetting the wind speed, and the new trend blows to indoor user, can make the user more comfortable, and the compressor is shut down this moment, can reduce the work efficiency of air conditioner under the prerequisite of guaranteeing user's use experience like this.
In another embodiment of the present invention, referring to fig. 1, in step S5, if the current mode is the daytime air supply mode and the current outdoor temperature is greater than the preset outdoor temperature value, the compressor is stopped, and the fresh air fan is operated at the preset air speed and intermittently started and stopped. Specifically, under the current mode is air supply mode daytime to when current outdoor temperature is greater than preset outdoor temperature value, because current outdoor temperature is higher relatively, when new trend fan introduced new trend to indoor, the higher new trend of temperature can make indoor temperature higher, thereby reduces the user and experiences the use of air conditioner.
Therefore, the fresh air fan runs according to the preset air speed, and the intermittent start and stop are realized, so that the influence of the fresh air with higher temperature on indoor users can be reduced on the premise of ensuring the air inlet temperature of the fresh air in the fresh air supply mode. In addition, the energy consumption of the air conditioner can be reduced.
Further, the start-up duration of the fresh air fan is t1, the shutdown duration is t2, and t1 and t2 satisfy the relation: t1 is more than or equal to 5min and less than or equal to 15min, and t2 is more than or equal to 3min and less than or equal to 7 min. Specifically, the starting time and the shutdown time of the fresh air fan are within a reasonable range, the starting time and the shutdown time of the fresh air fan can be adjusted according to the specific value of the current outdoor temperature, the fresh air fan can stably and reasonably work under different conditions, the ranges of the starting time and the shutdown time are reasonable, and the reliability of the control method of the air conditioner can be improved.
In an embodiment of the present invention, referring to fig. 1, in step S5, if the current mode is the night cooling/dehumidifying mode and the current outdoor temperature is lower than the preset outdoor temperature value, the compressor is stopped and the fresh air fan is operated with the minimum air volume. Specifically, when the current mode is the night cooling/dehumidifying mode, the user in the room is generally sleeping at this time, the temperature of the indoor environment around the sleeping user cannot be too low, otherwise a cold is likely to occur, when the current outdoor temperature is lower than the preset outdoor temperature value, the fresh air fan operates according to the minimum air quantity due to the lower current outdoor temperature, when the fresh air fan introduces outdoor fresh air into the room, the fresh air introduced into the room by the fresh air fan according to the minimum air quantity is enough to meet the requirements of the user in the sleep state, the user can be in a comfortable environment without cold, and the compressor can stop working at the moment, thereby not only avoiding unnecessary refrigeration of the compressor, the energy consumption of the air conditioner can be reduced, the health of the user can be further ensured, and the user can be prevented from catching a cold.
