Problems solved by technology

[0003] The problem solved by the invention is that the defrosting of the existing air conditioner is not complete, and water droplets are attached to the copper tubes and fins, resulting in too fast frosting of the condenser and poor heat exchange effect

Abstract

The invention provides a control method and device for reducing the frosting rate of the condenser, and an air conditioner. The condenser is provided with an ultrasonic device. The control method includes: after the air conditioner enters the defrosting mode, start recording the defrosting time, and detect the temperature of the outer disk; according to the defrosting time and the temperature of the outer disk, control the operating status of the external fan and the ultrasonic device. The control method for reducing the frosting rate of the condenser provided by the present invention controls the operation of the external fan and the ultrasonic device by using the temperature of the outer disk and the defrosting time as parameters in the defrosting mode, and utilizes the mechanical oscillation and cavitation of the ultrasonic device The liquid droplets are atomized and separated from the surface of the fins and copper tubes, and the liquid droplets are blown away by the reverse air supply of the external fan, which solves the phenomenon of incomplete defrosting, effectively reduces the frosting rate of the condenser in the next operation cycle, and ensures The heating effect of the air conditioning system.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for reducing the frosting rate of a condenser and an air conditioner. Background technique [0002] For the frosting phenomenon of the low-temperature heating condenser of the air conditioner, at present, the defrosting is mainly carried out through the periodic four-way reversing method. Due to the hydrophilicity of copper tubes and fins, this method of defrosting has incomplete defrosting. When the air conditioner determines that defrosting is over, there are still water droplets attached to the surface of the copper tube and fins, which will cause the attached water droplets to quickly form an ice layer when the air conditioner is running in the next cycle, which will accelerate the frosting of the condenser and hinder the heat transfer of the condenser , leading to a decrease in heating capacity. Contents of the invention [0003] The ...
