(Test Method)Standard Test Method for Energy Performance of Rack Conveyor, Hot Water Sanitizing, Commercial Dishwashing Machines
Standard Test Method for Energy Performance of Rack Conveyor, Hot Water Sanitizing, Commercial Dishwashing Machines
SIGNIFICANCE AND USE
The maximum energy input rate test is used to confirm that the dishwasher is operating at the manufacturer’rated input prior to further testing. This test method also will indicate any problems with the electric power supply, gas service pressure, or steam supply flow or pressure.
Tank and booster temperatures, as well as water consumption, are adjusted to NSF specifications to insure that the test is applied to a properly functioning dishwasher.
Because much of a dishwasher’operating period is spent in the idle condition, tank heater and booster idle energy consumption rate(s) are important parts of predicting dishwasher’energy consumption.
The washing energy test determines energy usage per rack. This is useful both as a measure for comparing the energy performance of one dishwasher to another and as a predictor of the dishwashers energy consumption.
Water-consumption characterization is useful for estimating water and sewage costs associated with dishwashing machine operation.
SCOPE
1.1 This test method evaluates the energy consumption of rack conveyor, hot water sanitizing, commercial dishwashing machines, hereafter referred to as dishwashers. It excludes rack conveyor, chemical sanitizing, commercial dishwashing machines, and dishwashers with multiple tanks and prewashing sections. This test method also excludes single temperature rack conveyor dishwashing machines. Dishwasher tank heaters are evaluated separately from the booster heater. This procedure does not address cleaning or sanitizing performance.
1.2 The following procedures are included in this test method:
1.2.1 Procedures to Confirm Dishwasher is Operating Properly Prior to Performance Testing:
1.2.1.1 Maximum energy input rate of the tank heaters (10.2).
1.2.1.2 Maximum energy input rate of the booster heater, if applicable (10.3).
1.2.1.3 Final sanitizing rinse water consumption calibration (10.4).
1.2.1.4 Booster temperature calibration, if applicable (10.5).
1.2.1.5 Wash tank temperature calibration (10.6).
1.2.1.6 Wash tank pump and conveyor motor calibration (10.7).
1.2.2 Energy Usage and Cycle Rate Performance Tests:
1.2.2.1 Washing energy performance test (10.8).
1.2.2.2 Tank heater idle energy rate (10.9).
1.2.2.3 Booster idle energy rate, if provided (10.10).
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
