Answer to Question 1

The air is cooled as it passes through one side of a tube-in-tube evaporator coil. Then water is drained off from the air as it leaves the coil. The cooled dry air picks up heat as it leaves the unit by the warm air entering.

Answer to Question 2

A static pressure sensor installed in the air flow.
