Ceiling Cassette Air Conditioner Explained - How It Works

In this video, I explain how a ceiling cassette air conditioning unit works by dissecting the components within. I'll show you how the drain system works, what are the drain pipe connection methods and how fresh air can be introduced through a ceiling cassette unit. In addition to the content of the video, it is recommended to have a separate filter for the fresh air duct because the fresh air doesn't go through the filter of the ceiling cassette unit. Without a fresh air filter, the cooling coil can very quickly becomes dirty.
