II.8.8 EEM accessory - Energy Meter
The EEM accessory allows certain unit features, such as those below, to be measured and displayed:
○
Power supply voltage and instantaneous current consumption of the unit
○
Instantaneous electric power consumed by the unit
○
Instantaneous power factor of the unit
○
Electricity consumption (kWh)
If the unit is connected via a serial network to a BMS or external supervisory system, the trends of the measured parameters can be stored and the
operating status of the unit itself checked.
II.8.9 FDL accessory - Forced download compressors
The FDL accessory (forced reduction of the power consumed by the unit) allows power consumption to be restricted according to the utility
requirements. The function, which can be set from the unit display, can be enabled via a digital signal, using time bands or as an input in the case of a
serial connection with an external BMS via Modbus.
In the presence of the EEM accessory, which allows the power consumed to be instantaneously measured, a specific maximum consumed power value
can be set and any utility requirement complied with.
EEO accessory – Energy Efficiency Optimizer
II.8.10
The EEO accessory allows the unit efficiency to be optimised by acting on the electrical absorption, thereby minimising consumption. The EEO
accessory identifies the optimal point that minimises the total absorbed power (compressors+fans) of the unit by actuating the fan rotation speed. It is
particularly effective in the partial load operation, a situation which arises for most of the useful life of the chiller. The energy efficiency index ESEER
therefore, increases up to 5%.
