Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0016] see figure 1 As shown, according to the embodiment of the present invention, the defrosting control method includes: turning on the defrosting mode; detecting the instant ambient temperature, and comparing the instant ambient temperature with the initial indoor ambient temperature; The ambient temperature is kept within the preset temperature range, wherein the initial indoor ambient temperature is the indoor ambient temperature when the defrosting mode is activated.

[0017] In the present invention, when the air conditioner is in the defrosting mode, the internal fan is turned on at the same time, and the indoor ambient temperature is kept within a reasonable range by adjusting the rotation speed of the internal fan, so that users can always obtain a better use experience. In ...

Abstract

The invention discloses a defrosting control method. The defrosting control method comprises the steps of: starting a defrosting mode; and detecting an instant environmental temperature, comparing the instant environmental temperature with an initial indoor environmental temperature, and adjusting the rotating speed of an inner fan according to a comparing result to keep indoor environmental temperature in a preset temperature range, wherein the initial indoor environmental temperature is indoor environmental temperature when starting the defrosting mode. The defrosting control method, disclosed by the invention, can solve the problems of long defrosting time and low defrosting efficiency in the prior art.

Description

technical field [0001] The invention relates to the technical field of air conditioning defrosting treatment, in particular to a defrosting control method. Background technique [0002] The existing defrosting technology generally is that in the case of heating, when the frost accumulated on the external unit reaches the level that needs to be defrosted, the air conditioner will switch to cooling, and the high-temperature and high-pressure refrigerant will be sent to the outside to release heat. At the same time, the indoor side is cooling and absorbing heat. In order to ensure comfort, cold air is not blown out during defrosting, and the internal fan is stopped at this time. In this defrosting method, due to the lack of heat required for defrosting due to the stop of the indoor fan, the defrosting time is longer. Contents of the invention [0003] Embodiments of the present invention provide a defrosting control method, which can solve the problems of long defrosting tim...
