Evaporator self-cleaning method capable of improving frost layer thickness and air conditioner

Abstract

The invention belongs to the technical field of air conditioners, and discloses an evaporator self-cleaning method capable of improving frost layer thickness and an air conditioner. The method comprises the following steps: the rotating speed of a fan and/or the working frequency of a compressor are adjusted, so that the primary dew formation is performed on the surface of an evaporator; the fan is stopped, or the rotating speed of the fan is adjusted as a frosting preset rotating speed, and/or the working frequency of the compressor is adjusted; the temperature of a copper tube on the surfaceof the evaporator is controlled to be lower than and equal to a preset frosting control temperature T for frost control, so that the mth frosting is performed on the surface of the evaporator, wherein m is an integer not smaller than 1; the rotating speed of the fan is adjusted as a dew formation preset rotating speed; the working frequency of the compressor or the openness of an electronic expansion valve is adjusted; the temperature of the copper tube on the surface of the evaporator is controlled to be lower than and equal to a preset dew formation control temperature T for dew control, sothat the nth dew formation is performed on the surface of the evaporator, wherein n is an integer not smaller than 2; the compressor is stopped; and the rotating speed of the fan is adjusted to defrost and dry the surface of the evaporator. In self-cleaning, thicker frost is formed on the evaporator; and in defrosting, the cleaning effect is improved through higher water current impact.

AI Technical Summary

Benefits of technology

This technology helps prevent damage caused by snow buildup from accumulating inside an outdoor machine's housing when it operates at low temperatures (even below zero). It also increases the efficiency with which heated gases enter through its intake port compared to traditional methods like refrigerant systems due to increased contact between warm surfaces instead of direct conduction coolers. Overall this innovative design enhances the performance and durability of the compressor system used within the building itself.

Problems solved by technology

Technological Problem addressed in this patents relates to improving an automatic cleaner for evaporation systems like those described earlier. Current methods involve adding or removing substances called mistging agents onto the surfaces where they can accumulate, causing them to stick together over time making their removal challenging without damaging other components within the system's electronic devices. Additionally, current solutions have limitations due to the small size of these mistering agent droplet sizes, leading to insufficient contact between the atomized liquid and the coolant plate surface when there is only one particle at risk of getting stuck.
