Answer to Question 1

The control of air temperature when using direct expansion coils is accomplished by regulating the refrigerant flow through the coil at the inlet. Indirect expansion coils use chilled water and typically the air temperature is controlled by regulating the water flow through the coil at the outlet.

Answer to Question 2

These may be electric, steam, or hot water.
