CREATE CLEAN
OPTIMISING ENERGY
AND CARBON
Many businesses are
experiencing demanding
effects from COVID-19
Alert Level periods. If
your rates of processing or hours of
operation have changed, your energy
efficiency and carbon emissions have
likely changed significantly.
It may be an appropriate time to
optimise systems and equipment
as part of continuous improvement.
Optimisation is a major energy
savings opportunity, which requires
little or no capex. Product quality is
often improved during the process.
It requires analysing trials using
varying set points or parameters. It
uses quality management such as
Lean or Six Sigma. EastPack's site
in Collins Lane, Te Puke saved 20%
energy last year. The site packs and
stores kiwifruit.
All of these savings were from
its refrigeration system, which
is continuously being improved.
Savings were due to:
• improved management and cool
store utilisation,
• floating compressor suction and
discharge pressures on six cool
rooms,
• reduced frequency of electric
defrosts, and
• modulating fan speeds after cool
rooms are fully loaded.
EastPack’s energy manager says:
“When evaporator fan speeds
were slowed to save electricity, the
cool rooms quickly lowered their
temperatures”.
This was because the fans were
putting less heat into the cool rooms
and required less refrigeration
capacity. Daily energy used by these
three cool rooms decreased from
6,000kWh per day to 4,500kWh per
day following the reduction in fan
speeds.
