Abstract: With the increasing popularity of air conditioning in daily life, the concept of healthy air conditioning is gradually gaining popularity. In ordinary air conditioning, there are inevitable problems such as bacteria, viruses, and dust accumulation on the evaporator surface during use. Based on this, air conditioning units with high-temperature sterilization and self-cleaning functions in the interior unit are increasingly favored by consumers. Proposing an optimal control scheme to further optimize the self-cleaning effect of self-cleaning air conditioning units by changing the setting values of relevant parameters during the operation of the self-cleaning function under rated and high humidity conditions. During this process, synchronously monitor parameters such as drainage at each stage of self-cleaning, system exhaust, and compare the optimization effects of different setting values on the self-cleaning function. This was then analyzed and demonstrated through experimental results.
