This class, the second of the series, begins with evaporators and their temperature differential (TD). Superheat what it is and how to measure it. Superheat is a valuable method for solving complex system problems in later classes. TD and humidity are also discussed.
Objectives
Describe the functions of an evaporator
Explain evaporator temperature and evaporator temperature difference (TD)
Describe evaporator types and styles
Explain latent heat, sensible heat, and super heat
Explain the relationship between evaporator TD and humidity
Describe evaporator defrost methods
