First look at the horizontal fan coil unit, its disassembly

As an SEO, I don't like to know too much about the product. After all, I know very well that it is difficult to stay in a company or an industry for a long time. I can't always have a deep understanding of the product's principles, ingredients, structure, production process, cycle, and even its scheduling, logistics, and packaging every time I change a new job.
I always hope to do my part, and at the same time, I hope that my colleagues and departments can do what they should do well, and at the same time consciously provide necessary help for the current networking and new media era. To be more precise, it is to consciously take photos, videos, etc., as well as the clear data they should provide.
Well, this is obviously asking too much. I can't do everything that I should do in theory in my position, just like other people have their own understanding of their work and make choices.
Unfortunately, it is often difficult to explain the features of these products that are worth writing hundreds of articles.
Just like the fan coil unit I will talk about this time, it needs to be installed horizontally and concealed. It can provide power like a fan or air conditioner to make the air flow, and it can also be equipped with other equipment such as an air conditioner outdoor unit to make us warm or cool.
Then what? I seem to have nothing to say. I can only go deeper and introduce its internal structure and principle. For example, it has one or more brushless motors that drive the fan, push the air in and pass through the internal surface cooler to heat or cool. Then there is really no principle to talk about.
Or I can praise its low noise, high efficiency and increasingly popular and necessary environmental protection characteristics, but what's the point? Price, acceptance, transportation, installation and maintenance are always factors that affect our acceptance of it as laymen.
