This powerpoint presentation begins by presenting the objectives of the study including the following: to measure actual water and energy usage of eight machines
consisting of two water-cooled and six air-cooled units;
to compare the field-measured water and energy usage rates
to ARI and/or manufacturer supplied (laboratory) testing
data; to
determine for each machine the annual water, wastewater,
and energy consumption and saving that could be achieved
by retrofitting with models that are more water/energy efficient; and,
capture field data that can be used to quantify the energy
saving potential for reductions in regional water distribution
(pumping) and wastewater treatment. This is followed by information on how ice machines work, and the Air-Conditioning and Refrigeration
Institute (ARI) Ice Machine Database. Study evaluation methods include the following:
one-month of water and electrical energy usage data was
collected;
water consumption was measured with a single-jet
paddlewheel turbine installed at the inlet line of each machine
and used in tandem with an electronic data logger that
recorded time-stamped pulses from each meter;
an energy data logger was installed in the circuit breaker
panel feeding each machine to record power and energy
consumption; and,
ice production was directly weighed for three consecutive
harvest cycles and then averaged. Presentation conclusions indicate the following: savings (water and energy) can be
achieved with more efficient machines;
potential for off-peak loading, the only appliance in
commercial food service; and,
ARI data is a good benchmark for specifying ice machines
air-cooled machines. Includes tables, figures.
