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 m
3
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.
