As I know, if you need your CR AC System operate all the whole day with highest reliability, your equipments should be standby up to 400% of your capacity.

LC-Shi,

Many thousand units work in such applications with 100% run time without any issues. The lesser or NIL the system cycling, it improves overall reliability of compressor, electrical switch gear etc.

Provided the system is a standard one manufactured and tested in lab by the manufacturer ...

In critical application, where down time is simply a NO...NO, have a second system as a stand-by with automatic switch-over.

All the components in the unit are delicately chosen, they might be the best components.
The computer room or station room air conditioner is quite popular this year.
