ED721208 Power Proportional Distribution (PPD)
3
(3) A PPD calculation result for a certain tenant is excessively large.
iTM distributes electric power based on operation data from an indoor unit.
If only one VRV indoor unit is in operation, electric power consumed by an outdoor unit increases because a compressor
is turned ON only for one indoor unit in operation.
Stopped indoor units do not consume energy power at stopping (standby electricity) because the compressor is turned
ON and the crankcase heater is turned OFF.
If accidentally keeping an air conditioner ON at a certain tenant, the power consumption will increase.
(4) When setting the Excluded Time, is there a way to get to know a PPD result of the time?
· A power pulse and a thermo. step are not counted during the excluded time.
There is no way to get to know a PPD result or a power pulse inputted during the excluded time.
