Physicists, help me understand this:
If they're referring to _power_, the unit should be _KW_, right?
And if they're referring to _energy_ consumed (in some interval of time), then it should be _KW⋅h_ (not _KW/h_). Right?
(And if so: the quantity is meaningless unless you specify _the interval of time_. eg: _“400 KW·h on an average day”_. No? I mean, my smartphone also consumes 400 KW·h… if I use it for long enough!)
The unit for “energy consumption for [period of time]” should be an _energy_ unit, like _joule_ or _kcal_. Or even _KW·h_.
So you could say any of this:
* “The lift consumes 10 J every hour”
* “The lift consumes 25.6 KW·h per hour”
* “The lift consumes 0.3 J / h”
* “The lift consumes 981 KW·h / h”
But not: “the lift consumes 400 KW / h”.
Right?
@tripu
Right, an assumption was made
@tripu
It does appear like a lot, maybe they meant the daily average, but then as you say the sign is really misleading
