I can provide you with some general information. The number of air conditioners installed per person worldwide can vary significantly based on factors such as climate, income levels, population density, and technological advancements.
Countries with hot and humid climates, such as those in tropical regions, tend to have higher air conditioner usage per capita. In contrast, countries with milder climates may have lower adoption rates. Additionally, developed nations often have higher air conditioner penetration due to higher income levels and greater access to cooling technologies.
Unfortunately, I don't have access to the specific data on the number of air conditioners installed per person worldwide or the most up-to-date statistics. To obtain accurate and current information on this topic, you may refer to reports from international organizations, government agencies, or market research firms that specialize in tracking and analyzing such data.
