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 a condenser and an air conditioner. An ultrasonic device is arranged on the condenser, and the control method comprises the steps of after the air conditioner enters a defrosting mode, starting to record the defrosting time, and detecting the temperature of an outer disc; and according to the defrosting time and the outer disc temperature, controlling the running states of an outer fan and the ultrasonic device. According to the control method for reducing the frosting rate of the condenser, in the defrostingmode, the outer disc temperature and the defrosting time are used as the parameters to control the operation of the outer fan and the ultrasonic device, the liquid drops are atomized and separated from the surfaces of the fins and the surface of a copper pipe through the mechanical oscillation and cavitation effects of the ultrasonic device, the liquid drops are blown away through the reverse airsupply of the outer fan, so that the phenomenon that the defrosting is not thorough is avoided, the frosting rate of the condenser in the next operation period is effectively reduced, and the heatingeffect of the air conditioner system is guaranteed.

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 ...
