Outdoor unit capacity save
●
Benefits may vary according to indoor and outdoor heat load.
●
If the operating rate is set very low, comfort may significantly deteriorate.
●
No reduction benefits would be obtained if the unit is operated below the set operation rate.
Peak cut operation
●
If the target electric power is set very low, comfort may significantly deteriorate due to the occur-
rence of Outdoor Unit Forced Stop every hour.
●
If the time interval is set too short, Outdoor Unit Stop would easily occur as compared to longer time
interval.
●
If the energy meter is not set to appropriate pulse unit (or pulse factor), control will become rough.
●
When the DX-
Kit is controlled by DDC or some other external controller, the temperature shift con-
trol is not performed to the DX-Kit.
When cooling and heating operations are mixed at indoor rotation control, effect may be small.
Energy saving control for Outdoor Air Unit and DX-
When energy saving control is performed for an Outdoor Air Unit or DX-Kit itself or outdoor units in
the refrigerant system to which the unit belongs, the unit may be stopped if the desired capacity is not
obtained or the energy saving function is limited.
When the Outdoor Air Unit and DX-Kit are used as an outdoor air introduction unit, perform the energy
saving control after understanding the affect because the ventilation function required by facility design
may not be satisfied.
