(e.g.)Pre-cooling and pre-heating control realises
comfortable temperature at the start of the day.
Based on a predetermined schedule, the
Manager
executes capacity control and intermittent operation of A/Cs so as
not to increase the discomfort index.
Reduces power consumption by 10 to 40%,
while maintaining room comfort.
Power limit control
This function switches the air conditioning system on before-
hand so that the temperature is just right when users arrive.
This function estimates the power consumption and oper-
ates at the maximum level within a limited range if the set
point is likely to be exceeded. This reduces power consump-
tion while maintaining comfort as far as possible.
· Alternative stop control of
indoor A/C units
· Outdoor unit capacity control
(only for VRV)
During cooling operation, this function shuts down the
air conditioning equipment and brings in cool air from
outside when the system determines that the outdoor
temperature is lower than the temperature setting. Us-
ing outside air for cooling reduces energy consumption.
