Example Embodiment

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0055] The embodiment of the invention discloses a defrosting control method and device. The defrosting is controlled by the current change rate of the outdoor fan of the air conditioner, so that the operation is simple and the defrosting can be reasonably controlled.

[0056] Such as figure 1 Shown is a defrost control method disclosed in the present invention, including:

[0057] S101. Control the air conditioner to run to a stable state, ...

Abstract

The invention discloses a defrosting control method. The defrosting control method comprises the following steps: controlling an air conditioner in a steady state, and remaining to operate for some preset time in the steady state; in real time detecting the operation current of an outdoor fan; judging whether the change rate of the operation current of the outdoor fan is not more than a preset value under a preset period or not, if so, controlling the air conditioner unit in a defrosting state. The defrosting process is controlled according to the current change rate of the outdoor fan of the air conditioner, in comparison with the prior art, the defrosting process is controlled according to the temperature of the outdoor tube of the air conditioner and the current value of the outdoor fan, the operation is relatively simple, the defrosting process is relatively reasonable and the defrosting effect is relatively better. The invention further disclose a defrosting control device.

Description

technical field [0001] The present invention relates to the technical field of air conditioning control, and more specifically, to a defrosting control method and device. Background technique [0002] When the heat pump air conditioner is heating, due to the difference in outdoor temperature and humidity, the outdoor unit of the air conditioner is prone to frosting. At present, most heat pump air conditioners use the detection of the temperature of the outer pipe and the current of the outdoor fan to judge the defrosting. It is easy to have problems such as defrosting by mistake, defrosting is not clean, or frost does not enter defrosting, which leads to waste of energy and affects the comfort of users. Contents of the invention [0003] In view of this, the present invention provides a defrosting control method and device, which controls the defrosting through the current change rate of the outdoor fan of the air conditioner, so that the operation is simple and the defro...
