Problems solved by technology

[0002] During the heating operation of the household split air conditioner, the outdoor unit is prone to frost at low temperatures. The system must be switched to cooling mode after a period of operation to defrost the heat exchanger of the outdoor unit. During the defrosting period, the room temperature will drop. Generally speaking, the fan does not turn on immediately after defrosting, and there is no air circulation at the air inlet of the air conditioner at this time, and the indoor temperature at this time cannot be detected.
In the current technology, after defrosting is finished, the ambient temperature before defrosting will continue to be used after the fan is turned on. In this way, the operating parameters of the air conditioner at this time, such as frequency, opening degree, etc., are calculated according to this temperature. Temperature drop, the operating parameters calculated by this method are unreasonable, often resulting in insufficient operating frequency and insufficient heat in the room

Embodiment 1

[0016] Embodiment 1: A method for predicting the temperature drop in defrosting of an air conditioner.

[0017] Such as figure 1 As shown, an air conditioner defrosting temperature drop prediction method, the specific steps are as follows:

[0018] S1, establish the mathematical model of temperature drop during defrosting in advance, specifically: detect the outdoor ambient temperature T 外 , Indoor ambient temperature T 内 , Indoor ambient temperature rise within 3 minutes △T1, inner tube temperature T 内管 and windshield F, with F*T 内管 As the ordinate, (T 内 -T 外 )* △T is used as the abscissa to set the temperature drop coefficient K correspondingly;

[0019] S2. After the air conditioner is turned on in the heating mode, the K value is determined according to the currently detected operating parameters of the air conditioner unit, and the defrosting time t is detected to calculate the temperature drop value △T2=t*(T 外 -T 内 )*K;

[0020] S3, detect the indoor ambient tem...

Embodiment 2

[0025] Embodiment 2: a computer-readable storage medium.

[0026] A computer-readable storage medium is used for storing a computer program, and when the computer program is invoked by a processor, the method for predicting the defrosting temperature drop of an air conditioner described in Embodiment 1 is implemented.

Embodiment 3

[0027] Embodiment 3: a kind of air conditioner.

[0028] An air conditioner includes a processor and a memory, the memory is used to store a computer program, and when the computer program is invoked by the processor, the method for predicting the defrosting temperature drop of the air conditioner described in Embodiment 1 is implemented.

Abstract

The invention provides an air conditioner defrosting temperature drop pre-judging method, a computer readable storage medium and an air conditioner. The method comprises the following steps that a mathematical model of temperature drop during defrosting is established in advance, an air conditioning unit is started to operate, the current indoor environment temperature is detected when the defrosting condition is met and a defrosting mode is started, the temperature drop value during defrosting is calculated according to the established mathematical model, the indoor environment temperature atthe end of defrosting is predicted and updated to be the latest indoor environment temperature, and the air conditioning unit operates corresponding operating parameters according to the latest indoor environment temperature. According to the method, the coefficient value is set by using the pre-established mathematical model, and the coefficient value is got and determined through the detected relevant parameters during first defrosting, so that the temperature drop value of the indoor environment is accurately calculated, the situation that the temperature continued to be used by operationis inaccurate after the defrosting of the air conditioning unit is finished is avoided, it is guaranteed that the operation frequency of the unit is stable, and the heating capacity meets the requirement, and the user experience is ensured.

Description

technical field [0001] The invention relates to the technical field of air-conditioning defrosting control, in particular to a method for predicting the temperature drop of an air-conditioning defrosting, a computer readable storage medium and an air conditioner. Background technique [0002] During the heating operation of the household split air conditioner, the outdoor unit is prone to frost at low temperatures. The system must be switched to cooling mode after a period of operation to defrost the heat exchanger of the outdoor unit. During the defrosting period, the room temperature will drop. Generally speaking, the fan does not turn on immediately after the defrosting is completed. At this time, there is no air circulation at the air inlet of the air conditioner, and the indoor temperature at this time cannot be detected. In the current technology, after defrosting is finished, the ambient temperature before defrosting will continue to be used after the fan is turned on...
