Ventilation properties

Power path

Identifies if this subsystem is on the critical or primary power path, or if it is not included in this energy system.

Calculation source

Identifies if the data of this subsystem is measured (live) or computed (without power meters).

Actual kW Nameplate

Sums up the total nameplate value of all equipment in this subsystem.

Usable fraction of nameplate w/o derating

Identifies the usable fraction of power that can be used within the devices in this subsystem without derating the value.

Redundancy

Identifies the redundancy of this subsystem. For example, if you have a redundant setup with two 80 kW UPS, this value is 2N.

Redundancy "+1" kW Increment

Identifies the loss in kilowatt caused by internal redundancy. (Only needed if redundancy option includes +1.) For example, if you have a 40 kW UPS with one spare 10 kW power module, this value would be 10 kW.

Derate Capacity fraction

Identifies the usable fraction of the nameplate value that can be used in this subsystem. For example, if you use a 20% safety margin, this value would be 0.8.

Typical PU

Identifies the power usage (PU) of this subsystem relative to the total power usage.

Fixed loss

Identifies the fraction of power that is the fixed loss of the subsystem.

Proportional loss

Identifies the fraction of power that is lost proportional to the load of the subsystem.

Square Law loss

Identifies the fraction of power that is lost proportional to the square of the load of the subsystem.

Dry bulb fixed loss

Identifies the fraction of power that is lost per degree Celsius dry bulb.
