Meanwhile, in order to avoid ambiguity, the preset temperature refers to a preset temperature of a user, and refers to a target temperature set for the air conditioner by the user according to the user's own needs, so as to meet the user's needs for heating or cooling the air conditioner, for example, people often set the air conditioner heating to be twenty or more degrees or even thirty or more degrees in winter.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
In the existing air conditioner defrosting technology, whether the air conditioner is controlled to enter defrosting is often determined by detecting parameters such as coil temperature, ambient temperature and the like and analyzing and processing the parameters with preset parameters such as air conditioner preset temperature and the like. The air conditioner defrosting method is often simple, the use requirements of users are not considered, accurate and effective defrosting is difficult to achieve, the problems of untimely defrosting, overlong defrosting time and the like easily occur, the heating performance of the air conditioner is influenced, and the use experience of the air conditioner of the users is further influenced.
In order to solve this problem, the present application proposes a defrosting control method, an air conditioner, and a computer-readable storage medium, which introduces a user-set temperature in an existing defrosting logic, and can be simply interpreted as: in the process of analyzing and processing defrosting parameters such as the temperature of an outer disk, the temperature of an outer ring and the like, user set temperatures are introduced, because different users often set different preset temperatures according to own heating requirements when using the air conditioner, especially on the heating requirements of the air conditioner; when the heating operation is carried out, the higher the user set temperature is, the larger the difference value between the set temperature and the inner ring temperature is, the larger the heating capacity requirement required by the user or debugging is, the higher the frequency required by the operation of the whole machine is, the temperature of the outer disc into which defrosting enters is correspondingly reduced, and the judgment condition of the difference value between the outer ring temperature and the outer disc temperature also needs to be correspondingly changed.

The temperature set by the user can be a target temperature set by actively adjusting the air conditioner through devices such as a remote controller and the like when the air conditioner is started; or the heating target temperature in the last heating mode of the air conditioner, that is, the user does not actively adjust the temperature, and the air conditioner operates in the last heating mode after entering the heating mode. According to daily heating requirements and use habits of people, people often set the T to be more than or equal to 20 ℃ in a heating mode.
S3, judging whether a first defrosting condition is met; if yes, go to step S4; if not, returning to the step S2;
and S4, defrosting is performed.
The first defrosting condition is TOuter plate≤T1-TIs provided withT1 is an air conditionerThe first preset temperature before leaving the factory, T1, is 15-18 ℃, preferably, T1 ═ 17 ℃.
If the first defrosting condition is not met, the temperature of the outer disc is higher and frosting is not easy to occur at the current temperature set by the user, and the air conditioner can operate according to the normal heating mode of the air conditioner and the set defrosting logic; if the first defrosting condition is met, the temperature of the outdoor coil of the air conditioner is relatively low at the current temperature set by the user, the hidden danger of frosting exists, and defrosting can be executed.
For the defrosting action in the application, the defrosting action can be the same as the action of normal reverse defrosting by reversing the four-way reversing valve of the conventional air source heat pump unit, belongs to the prior art in the field and is not repeated.
Compared with the prior art, the defrosting control method and the defrosting condition are provided based on the user set temperature, when the user set temperature is lower (for example, 20 ℃), the heating requirement of the user is low, the heating load of the air conditioner is small, the frequency of the compressor is small, the temperature of the outer disc is reduced less, and T1-TIs provided withThe difference is relatively large, and timely defrosting can be guaranteed in the process that the temperature of the outer plate is gradually reduced along with the operation of the air conditioner by analyzing by using the first defrosting condition; when the temperature set by the user is higher (for example, 31 ℃), the heating demand of the user is high, the heating load of the air conditioner is large, the frequency of the compressor is higher, the temperature of the outer plate is reduced more, and T1-TIs provided withThe difference is relatively small, a certain heating process can be guaranteed firstly along with the operation of the air conditioner, then defrosting is carried out after a defrosting condition is met, the heating requirement of a user can be fully met, the use feeling of the user is enhanced, and meanwhile, the condition that the air conditioner actually has no frost but still carries out defrosting misoperation can be reduced to a certain extent.
