[0023] see figure 1 , which is a schematic flowchart of an air conditioner defrosting control method provided in the first embodiment of the present invention. The air conditioner defrosting control method includes:

[0024] Step S10, controlling the air conditioner to perform heating.

[0025] It can be to control the air conditioner to perform normal heating, or to control the air conditioner to be in heating mode.

[0026] Step S20, according to the compressor current value I d It is judged whether the air conditioner is in the frosting process.

[0027] For example, it can be according to the said I d Judgment of the trend of change; if the monitoring of the I d It is gradually decreasing, indicating that the air conditioner is in the process of frosting; therefore, by monitoring the I d The degree of attenuation determines the frosting condition.

[0028] It is also possible to obtain the compressor current value I after controlling the air conditioner to run for a...

Abstract

The invention provides an air conditioner defrosting control method and device and an air conditioner. The air conditioner defrosting control method comprises the steps that the air conditioner is controlled to conduct heating; whether the air conditioner is in a frosting process or not according to the compressor current value Id is judged; when it is judged that the air conditioner is in the frosting process, the frosting state of the air conditioner is determined according to the current exhaust temperature value Td and the current indoor environment temperature value T1; and the air conditioner is controlled to perform corresponding defrosting action according to the frosting state of the air conditioner. The problem that the comfort of the indoor environment is affected due to the fact that defrosting is frequent is solved.

Description

technical field [0001] The invention relates to the technical field of defrosting control, in particular to an air conditioner defrosting control method, an air conditioner defrosting control device and an air conditioner. Background technique [0002] Existing air conditioners generally perform defrosting control based on the temperature of the external unit coil, by monitoring the attenuation of the external unit coil temperature, or monitoring that the external unit coil temperature reaches a certain set condition, and then perform defrosting. [0003] This defrosting control method is too simple, resulting in frequent defrosting, which affects the comfort of the indoor environment. Contents of the invention [0004] The problem solved by the invention is: frequent defrosting affects the comfort of the indoor environment. [0005] In order to solve the above problems, an embodiment of the present invention provides an air conditioner defrosting control method, includin...
