1.3.2 WATER
Magnitudes of each water channel:
Flow : water flow measured in liters per hour [ L/h ] or cubic meters per hour
[ m
3
/h ].
Consumed water : quantity of water consumed calculated from the flow rate
and elapsed time. Its units will be litres [ L ] or cubic metres [ m
3
] as indicated by
parameter.
Global water measures:
Flow : sum of the flow of each channel. Measured in litres per hour [ L/h ] or
cubic meters per hour [ m
3
/h ], as indicated by parameter.
Consumed water : sum of the water consumed by each of the channels.
Measured in litres [ L ] or cubic meters [ m
3
] as indicated by parameter.
ANNEX I. Flow calculation details how to calculate the flow rate from the frequency
measured by the flow meter.
1.3.3 HEAT/COOL QUANTITY
The magnitudes measured by each channel are:
Temperature difference : difference between forward temperature and return
temperature.
Heat quantity : calorific energy consumed by the associated water channel
when the temperature difference is positive. It is measured in joules [ J ].
Cool quantity : calorific energy consumed by the associated water channel
when the temperature difference is negative. It is measured in joules [ J ].
Heat/cool quantity : sum of the calorific energy consumed during both heating
and cooling. It is enabled by an ETS parameter and is always measured in
joules [ J ].
