The present embodiment provides a method for controlling an air conditioner, which may be applied to the air conditioner provided in the above embodiment, referring to a flowchart of the method for controlling an air conditioner shown in fig. 4, the method mainly includes the following steps S402 to S406:
step S402: when the air conditioner is in the cooling mode operation, whether an enhanced cooling instruction is received or not is detected.
The enhanced refrigeration instruction (also called as a PTEC instruction) may be input by a user through a remote controller or a PTEC button on a control panel, and when the enhanced refrigeration instruction input by the user is received, it is determined that the air conditioner can apply the enhanced refrigeration effect of the refrigeration sheet assembly.
Step S404: if yes, judging whether the air conditioner has insufficient refrigeration.
When the enhanced refrigeration instruction is received, whether the air conditioner meets the preset refrigeration deficiency condition is further judged according to the current operation state of the air conditioner, and if the preset refrigeration deficiency condition is met, the current refrigeration deficiency of the air conditioner is determined.
Step S406: when the air conditioner is insufficient in refrigeration, the refrigeration piece is controlled to be electrified and started.
When the air conditioner simultaneously meets the conditions of receiving an enhanced refrigeration instruction and the preset refrigeration shortage, determining that the air conditioner needs to perform enhanced refrigeration, electrifying the refrigerating sheet, and leading the cold end (with the temperature of about-5 to-10 ℃) of the refrigerating sheet to be at the air inlet position of the air conditioner after the refrigerating sheet is electrified, so that the air outlet temperature is reduced and the refrigeration capacity is improved at the same time through air cooling heat exchange; the hot end of the refrigerating plate is positioned in the water receiving tank (50-60 ℃), and the air conditioner is utilized to form condensed water for cooling.
According to the control method of the air conditioner, the air conditioner receives the enhanced refrigeration instruction, and when the condition of insufficient refrigeration occurs, the refrigeration pieces in the air conditioner are electrified to enable the cold ends of the refrigeration pieces to generate cold, so that the refrigeration effect of the air conditioner is enhanced, the refrigeration capacity is improved, and the user experience is further improved.
In one embodiment, the method for determining whether the air conditioner has insufficient cooling includes: judging whether the air conditioner meets a plurality of conditions in the following preset refrigeration deficiency conditions, if so, determining that the air conditioner has insufficient refrigeration; the preset refrigeration shortage condition includes the following conditions (1) to (5):
(1) the temperature of an inner disc of the air conditioner is higher than a first preset temperature; wherein the first preset temperature is related to the rotating speed of the inner fan.
When the rotating speed of the inner fan is less than or equal to B, the value of the first preset temperature can be 10-12 ℃, and is preferably 12 ℃; when the rotating speed of the inner fan is less than or equal to C, the value of the first preset temperature can be 13-15 ℃, and the first preset temperature is preferably 14 ℃; when the D is less than or equal to the rotating speed of the inner fan, the value of the first preset temperature can be 16-18 ℃, and the preferred value is 16 ℃; and when the rotating speed of the inner fan is less than B, the power supply is controlled to stop supplying power to the refrigerating sheet. The B can be a rotating speed value corresponding to a low windshield of the inner fan, the C can be a rotating speed value corresponding to a middle windshield of the inner fan, and the D can be a rotating speed value corresponding to a high windshield of the inner fan. When the rotating speed of an inner fan of the air conditioner is higher, the temperature of an inner disc is higher, the air outlet temperature of the air conditioner is higher, and the refrigerating effect is poorer.
(2) The compressor of the air conditioner is in a running state and the rotating speed of the inner fan is more than or equal to the minimum windshield.
The compressor of the air conditioner is in an operation state, the rotating speed of the inner fan is greater than or equal to the minimum windshield (namely, a low windshield), and the air conditioner is in a cooling mode. When interior fan wind speed is lower, the air-out temperature is low under the same ability, and it is reasonable to assess refrigeration effect, need not to open the refrigeration piece, therefore interior fan rotational speed needs the minimum windscreen of more than or equal to.
(3) The current refrigeration mode of the air conditioner is obtained by switching the heating mode, the time of the air conditioner running in the heating mode is more than or equal to first preset time, and the time of the air conditioner running in the refrigeration mode is more than second preset time.
And (3) when the running time of the air conditioner in the heating mode exceeds a first preset time, and after the air conditioner is switched to the cooling mode to run, the continuous running time of the inner fan is greater than a second preset time, determining that the air conditioner meets the condition (3). The value range of the first preset time can be 10-15 min, preferably 10min, and the value range of the second preset time can be 5-8 min, preferably 5 min. Because the air conditioner runs for a long time under the heating mode and is switched into the cooling mode without condensate water at the initial stage, if the refrigerating sheet is started within the second preset time just entering the cooling mode, the temperature of the hot end of the refrigerating sheet is high, the refrigerating sheet is easy to damage, and the condition (3) is required to be met in order to improve the reliability of the air conditioner.
(4) The difference value between the current indoor environment temperature and the set temperature is greater than or equal to a second preset temperature.
When the indoor environment temperature is far higher than the set temperature, the refrigerating effect of the air conditioner is poor, the refrigerating effect needs to be enhanced for the air conditioner, and the refrigerating capacity is improved. The value range of the second preset temperature can be 3-4 ℃, and the preferred value is 3 ℃.
(5) The difference value between the current indoor environment temperature and the set temperature is larger than a third preset temperature and smaller than the second preset temperature, and the fluctuation range of the running frequency of the compressor in third preset time is smaller than the preset frequency.
The value range of the third preset temperature can be 1-2 ℃, when the difference value between the indoor environment temperature and the set temperature is larger than the third preset temperature and smaller than the second preset temperature, the air conditioner can increase the frequency of the compressor to improve the refrigeration effect according to the common refrigeration control, and when the frequency of the compressor is continuously maintained in the fluctuation range of the preset frequency (plus or minus 2Hz) and reaches the third preset time, the frequency of the compressor can not be increased, and the refrigeration piece needs to be electrified to improve the refrigeration experience of the air conditioner. The value range of the third preset time can be, for example, 2 to 5min, and a preferred value is 3 min.
