Title: Innovations by Hongjin Wu in Air Conditioning Technology

Introduction

Hongjin Wu is a notable inventor based in Shandong, China. He has made significant contributions to the field of air conditioning technology, holding a total of 4 patents. His innovative methods focus on improving the efficiency and cleanliness of air conditioning systems.

Latest Patents

One of his latest patents is a method for cleaning air conditioners. This method involves controlling frosting on the surface of a target heat exchanger in response to a cleaning instruction. After the frosting completion condition is met, the process includes defrosting the frost on the heat exchanger. Once the defrosting completion condition is achieved, the surface temperature is reduced to a sterilization temperature, allowing for quick cooling sterilization. This process effectively strips dirt such as dust from the heat exchanger and exposes deep bacteria, which are then killed by the sharp temperature change during the transition from defrosting to quick cooling.

Another significant patent is for a self-cleaning method for an air-conditioner heat exchanger. This method includes controlling the air conditioner to enter a self-cleaning mode and detecting the ambient temperature of the heat exchanger to determine a target evaporating temperature. The method adjusts the evaporating temperature accordingly and controls the heat exchanger to frost. After the surface is covered with frost or ice, the air conditioner enters a defrosting mode.
