Abstract

The invention discloses a defrosting method of an air conditioner. The method comprises the steps that S1. a heating mode of a compressor is carried out; S2. the fact that an outdoor fan is shut down at intervals is detected, and whether compressor accumulative operation time t reaches first preset time t1 is detected; S3. when t is larger than or equal to t1, a defrosting stage is carried out; S4. outdoor fan operation is detected, whether t is larger than second preset time t2 is detected, and the difference value delta T (delta T = T2 - T1) of the temperature T2 of an indoor heat exchanger and indoor environment temperature T1 is compared with a preset threshold value new delta T; S5. when t is larger than t2 and is smaller than third preset time t3, whether delta T is smaller than new delta T is judged; S6. when delta T is smaller than new delta T, the defrosting stage is carried out; S7. when t is larger than t3, whether delta T is smaller than new delta T + 2 DET C is judged; S8. if delta T is smaller than new delta T + 2 DET C, the defrosting stage is carried out; and S9. defrosting is over. According to the defrosting method, the operation that existing frost is removed, and when no frost exists, no processes are carried out can be achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air conditioner defrosting method. Background technique [0002] At present, the defrosting of air conditioners is controlled by the combination of outdoor heat exchanger temperature sensor or indoor temperature sensor and timing defrosting. The above two defrosting methods are either expensive, or there is a problem of clean frosting or no frosting. affect the heating effect. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to propose a defrosting method for an air conditioner that can realize defrosting with frost and exit without frost. [0004] According to the defrosting method of an air conditioner according to an embodiment of the present invention, the air conditioner includes a compressor, an indoor fan, an indoor heat exchang...
