1. list the various refrigeration and air-conditioning controls and their functions.
2) explain adiabatic saturation and thermodynamic wet-bulb temperature. When are the adiabatic and wet-bulb temperatures equivalent for atmospheric air?
3) what is metabolism? What is the range of metabolic rate for an average man? Why are we interested in the metabolic rate of the occupants of a building when we deal with heating and air-conditioning?
