●● On a compressed air system a safety valve would generally be
installed on the
Answer: Air receiver
●● Variable air volume system
Answer: Typically use the VFD's to save energy
●● In figure 1.3, a fool call for cooling would be at what branch
pressure to the damper motor
Answer: 3PSIG
●● A ratio relay would be used to
Answer: Controlled the sequence of actuators
●● when an actuated device is said to be normally open, that means the
device is open with
