An air treatment unit for treatment of an air stream, including a pad having a multitude of narrow air-flow channels, the walls of which are formed by corrugated sheets of a stiff material, the sheets being positioned and fixed generally in parallel planes next to each other in such a way that, as seen from an inlet side of the pad to an outlet side thereof, the channels formed by the corrugations of any two sheets located next to each other extend in two different directions the vertical plane of the respective sheet. At least in a central region of the pad, all sheets are positioned obliquely sideways, whereby all channels extend obliquely sideways relative to inlet and outlet surfaces of the pad.

 

Why are air conditioning units harmful?

Today's Air Conditioning units aren't as harmful as they once were. Todays models come with filters that can be cleaned and a lot of Air Conditioners have drainage holes that the water can drip out of. They used to be dangerous because stale water stayed inside of them and fungus and other things not good for humans to breath, caused one of the most dangerous outbreaks in American History. That was Legionares Disease. I don't remember how many people died until the Scientists found out what was causing these people to die and how to cure it. As with anything, if Air Conditioners are maintained they aren't dangerous to anyone's health.

Air conditioner manufacturers face the challenge of improving efficiency and lowering costs. Because of the environmental concerns, working fluids now consist typically of ammonia or water. New research is under way to design new working fluids and better system components to keep up with rapidly expanding markets and applications. The competitiveness of the industry should remain strong, driving more innovations in manufacturing and design.
