Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] When the condenser of the air conditioner is not frosted, the airflow can pass through the fins of the condenser and reach the external fan smoothly. At this time, it bears the largest load compared to the external fan. If the condenser is full of frost, the airflow cannot pass through the condenser. At this time, it bears the minimum load relative to the external fan. Compared with the DC motor such as the external fan, under the same voltage, the magnitude of the different load currents is not the same. The defrosting of the air conditioner of the present invention The control method is to use the...

Abstract

The invention provides an air conditioner and a frost removal control method of the air conditioner. The air conditioner comprises a controller, an outdoor direct current fan, a condenser and a current detecting unit which detects the current changes of the outdoor direct current fan and feeds the detection result back to the controller. The frost removal control method of the air conditioner comprises the following steps: a, judging whether the air conditioner is frosted through the current changes of the outdoor direct current fan and the temperature of the condenser; and b, judging whetherthe frost removal is finished through the current changes of the outdoor direct current fan and the temperature of the condenser. The conditioner and the frost removal control method of the air conditioner can judge whether the condenser of the air conditioner is frosted and whether the frost removal is finished together by combining the temperature of the condenser with the current changes of theoutdoor direct current fan, and have the advantage of accurate and intelligent frost removal.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner capable of intelligent defrosting and a defrosting control method thereof. Background technique [0002] The air conditioner is a widely used air-conditioning equipment. Its main function is to adjust the temperature and humidity of the air. In exchange, during the heating process of the air conditioner, the temperature of the outdoor condenser is low. In an environment with low outdoor temperature, frosting will occur on the outdoor condenser, which will affect the normal use of the air conditioner. Therefore, the defrosting control method of the air conditioner It is an important link in the automatic control of air conditioners, and it is also an important subject in the industry. In the prior art, defrosting control methods mainly include the following types: 1. Timing defrosting method, that is, whenever the air conditioner is heating and heating for a fix...
