STATUS MAIN MENU SELECT
The Energy Status display can be selected by pressing the ENERGY
STATUS button. The following items and their present values will
be displayed on the right side of the screen by pressing the up and
down arrows.
AVERAGE PACKAGE kW HOURS − This displays the average
package kW per hour for the time period that was started by
selecting the reset averaging setpoint. This value includes the
blower power usage.
AVERAGE % CAPACITY − Displays the compressor’s average
percent capacity for the time period that was started by selecting
the reset averaging setpoint. The value is determined by taking the
average package kW per hour, removing the blower power usage
and then dividing that number by the motor kW per hour for that
size of compressor at 100% capacity.
AVERAGE CAPACITY − Displays the compressor’s average capacity
in cfm or m3 for the time period that was started by selecting the
reset averaging setpoint.
ENERGY COST − Displays the energy cost of the compressor for
the time period that was started by selecting the reset averaging
setpoint. This is calculated by multiplying the kW hours of the motor
and the blower by the energy rate.
ENERGY SAVINGS − Displays the energy savings of the compressor
for the time period that was started by selecting the reset averaging
setpoint as compared to a conventional compressor. This value is
determined by calculating how much a conventional compressor
motor would cost to operate at the same average capacity and then
subtracting the motor energy cost of the Nirvana compressor from
it. It is assumed that the blower cost is the same in both packages.
LIFETIME ENERGY SAVINGS − Displays the lifetime energy savings
of the compressor at the existing energy rate and at the average
percent capacity as compared to a conventional compressor.
