(Test Method)Standard Test Method for Energy Performance of Single-Rack Hot Water Sanitizing, Door-Type Commerical Dishwashing Machines
Standard Test Method for Energy Performance of Single-Rack Hot Water Sanitizing, Door-Type Commerical 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 would also indicate any problems with the electric power supply, gas service pressure, or steam supply flow or pressure.
The tank and booster temperature are verified and water consumption is adjusted to NSF specifications to ensure 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 is an important part of predicting an end user’energy consumption. The test is run with the door(s) open and with the door(s) closed, so that the energy use of both end-user behaviors can be characterized.
A washing energy test generates an energy per rack usage. This is useful both as a measure for comparing the energy performance of one dishwasher to another and as a predictor of an end users energy consumption.
SCOPE
1.1 This test method covers the evaluation of the energy consumption of single-rack, hot water sanitizing, door-type commercial dishwashers (hereafter referred to as dishwashers). This includes under the counter single rack, hot water sanitizing, door type commercial dishwashing machines. This test method excludes single temperature door-type machines. Dishwasher tank heaters are evaluated separately from the booster heater. Dishwashers may have a remote or self-contained booster heater. This test method 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 (see 10.2).
1.2.1.2 Maximum energy input rate of the booster heater, if applicable (see 10.3).
1.2.1.3 Water consumption calibration (see 10.4).
1.2.1.4 Booster temperature calibration, if applicable (see 10.5).
1.2.1.5 Wash tank temperature calibration (see 10.6).
1.2.2 Energy Usage and Cycle Rate Performance Tests Washing energy test (10.7).
1.2.2.2 Tank heater idle energy rate (door(s) open and door(s) closed) (see 10.8).Booster idle energy rate, if provided (see 10.9).
1.3 The values stated in inch-pound units are to be regarded as 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.
