Working on the A/C system is no different than working on any other automotive A/C system. They have all the sameFile Size: KB. Route Two/Heating – Air enters into the heating duct (D). Here the air will pass over a set of heating coils that heat the passing air. Next it passes over the humidifier. If the relative humidity of the passing air is too low the humidifier will add moisture to the air and will continue moving through the ductwork towards the mixing box (F). the physics of HVAC processes in the conduct of design work. Problem Solving Every HVAC design involves, as a first step, a problem-solving pro-cess, usually with the objective of determining the most appropriate type of HVAC system for a specific application. It is helpful to think.
