With the continuous improvement of the industrial design level and the application of new processes, new materials, new shapes and new technologies to the air conditioner, not only various air conditioners are developed, but also the control methods of the air conditioner in different environments are correspondingly improved.
Taking the heating operation process of the air conditioner as an example, the compressor discharges high-temperature refrigerants, and the high-temperature refrigerants directly enter the indoor evaporator to exchange heat so as to achieve the effect of blowing hot air indoors. However, the temperature of the coil of the indoor evaporator gradually rises in the process, and when the temperature of the indoor evaporator rises to a certain degree, the compressor is easily overloaded and even burnt, which is not beneficial to ensuring the reliability of the operation of the air conditioner.
The conventional air conditioner has a protection function of preventing the temperature of the indoor evaporator from being too high, usually the protection treatment is carried out by detecting the temperature of a coil pipe of the indoor evaporator in various ways of regulating and controlling the frequency of a compressor, regulating and controlling the rotating speed of a fan, even stopping the air conditioner and the like when the temperature of the coil pipe reaches the protection temperature, and after the temperature of the indoor evaporator is reduced to a required value, a normal heating operation state is recovered or the air conditioner is restarted.
Although the control method in the prior art can solve the problem of overhigh temperature of the indoor evaporator, the cooling speed of the indoor evaporator is relatively slow, so that the time of the whole protection processing process is long, and the air conditioner can recover the normal heating running state only after a long protection processing time, thereby influencing the use experience of a user.
Disclosure of Invention
In view of the above, the present invention is directed to a control method of an air conditioner, and a computer readable storage medium, so as to solve the problem in the prior art that the processing time of the air conditioner for protecting the indoor evaporator at high temperature is long.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a control method of an air conditioner, comprising: step one, an air conditioner runs in a heating mode; step two, detecting the coil temperature Tn and the outdoor environment temperature Tw of the indoor evaporator by the air conditioner; the air conditioner judges whether Tn and Tw simultaneously meet a rapid cooling condition; if so, executing a rapid cooling process of the indoor evaporator; the rapid cooling condition is as follows: tn is more than or equal to a first preset temperature T1, tw is less than or equal to a second preset temperature T2; the quick cooling process is characterized in that a fresh air function of the air conditioner is started, and outdoor cold air is introduced to pass through the indoor evaporator. Wherein T1 is 54-60 ℃ and T2 is 8-15 ℃. Thereby this application detects, the analysis through coil pipe temperature, the outdoor ambient temperature to indoor evaporator, and after satisfying the rapid cooling condition, the new trend function is directly opened to the air conditioner, introduces outdoor cold air and passes through indoor evaporator. The mode can more directly and efficiently carry away the heat of the indoor evaporator, shorten the processing time of high-temperature protection of the indoor evaporator, ensure that the air conditioner can be quickly recovered to a normal heating operation state, and is favorable for ensuring the use experience of a user; in addition, the control method can reduce the occurrence probability of the air-conditioning shutdown protection to a certain extent, so that the heat load of the indoor evaporator can be reduced to the maximum extent under the condition that the air-conditioning shutdown protection does not occur.

and S10, stopping the temperature reduction process of the indoor evaporator by the air conditioner, recovering to a normal heating operation state, and returning to the step S1 or the step S2. Therefore, by monitoring the cooling state of the indoor evaporator, on one hand, under the condition that the temperature of the indoor evaporator is difficult to reduce, if the temperature of the indoor evaporator is always maintained at a higher temperature, the air conditioner is stopped in time, and the damage to components is avoided; on the other hand, after the indoor evaporator is cooled normally and the temperature is lower than T3, the air conditioner stops the corresponding cooling process and returns to the normal heating running state, so that the heating requirement of the user is guaranteed.

For the present application, mainly aim at the air conditioner heating in-process, prevent the too high protect function of indoor evaporator temperature. After the air conditioner starts to operate, firstly, step S1 is performed to confirm the operation mode of the air conditioner, if the air conditioner is in the heating mode, the control method of the air conditioner in the present application is continuously executed, and if the air conditioner is not in the heating mode, the air conditioner can normally operate according to other modes.

S6', the air conditioner performs a conventional indoor evaporator cooling process.
For step S6', when the current outdoor temperature is relatively high and the cooling effect of the introduced fresh air is not obvious, the air conditioner in the present application may also adopt a conventional indoor evaporator protection processing procedure, such as reducing the frequency of the compressor, increasing the rotating speed of the indoor fan, and the like. In view of the conventional indoor evaporator protection process, the corresponding prior art can be adopted, and will not be described herein.
Therefore, through the steps S1-S6, when the temperature of the indoor evaporator is detected to be too high in the heating process of the air conditioner, the outdoor environment condition is detected and analyzed firstly, and when the outdoor temperature is low, the air conditioner directly starts the fresh air function to introduce outdoor cold air to pass through the indoor evaporator. The mode can more directly and efficiently take away the heat of the indoor evaporator, shorten the processing time of high-temperature protection of the indoor evaporator, enable the air conditioner to be quickly recovered to a normal heating running state and be beneficial to ensuring the use experience of users; in addition, the control method can reduce the occurrence probability of the air-conditioning shutdown protection to a certain extent, so that the heat load of the indoor evaporator can be reduced to the maximum extent under the condition that the air-conditioning shutdown protection does not occur.

S8, judging whether Tn is larger than T1 by the air conditioner; if yes, stopping the air conditioner; if not, performing step S9;
if Tn is greater than T1 in the cooling process of the indoor evaporator, the current cooling measures are described, if fresh air is introduced for cooling (step S6), the frequency of the compressor is reduced (step S6 '), the rotating speed of the indoor fan is increased (step S6'), and the like, the temperature of the indoor evaporator cannot be reduced, the compressor is overloaded when the air conditioner is continuously operated, even the compressor is burnt, the reliability of the operation of the air conditioner is not facilitated to be guaranteed, therefore, the air conditioner is shut down in time, and the damage of components is avoided.
Meanwhile, in the condition, certain parts of the air conditioner can be in failure, and when the air conditioner is stopped or the condition is continuously generated for multiple times, an air conditioner failure alarm can be sent out to remind a user of repairing the possible failure.
