Redundant system
Redundant system
(OP)
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.

- 100% redundancy means if anything fails 100% capacity is available, ie two units at 100% capacity, 3 units at 50% capacity, 4 units at 33% capacity etc
- 50% redundancy means if anything fails min 50% capacity is available, ie two units at 50% capacity are required (or 3 at 33% etc)
For this particular project the requirement was 75% redundancy so four units at 25% full load are being installed, if any one fail 75% capacity is available which is still sufficient for most of the time.
