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.
