    Redundant system

    thanks all. two unit each with 100% load means 100% redundancy. now the question is about 50% redundancy.

    Redundant system

    The client want us to design a 50% redundant HVAC system for them. In my opinion, 50% redundancy means we need 3 rooftop units with 50% capacity for each, anytime we just run 2 units to get 100% capacity and another one will be the backup, is that correct? Thanks.
