# "Adaptive control systems" refers to a clothes washer control system which is capable of

automatically adjusting washer operation or washing conditiäns, without the need for consumer intervention and/or actions, based on characteristics of the test load placed in the clothes container. Examples would be clothes washer control system independent selection, modifications, or absolute control of water fill level, wash water temperature, agitation and/or tumble cycle time, number of rinse cycles, spin speed, etc. Note: The energy consumption of any adaptive system which relies on the use of, detection of, or the presence of either soil, soap, suds, or any additive laundering substitute or complimentary product to alter the "normal" operation of the clothes washer must be detemined following the field test procedures defined in section 6:1;

# 6 FIELD TESTING No,iconventional Wash System Energy Consumption Test 

# For washer controls or systems that cannot be adequately measured for energy consumption by the test procedure, or cannot be calculated using a procedure generally accepted by DOE and other manufacturers, a field test must be conducted. The field test shall consist of a minimum of 10 test units and 10 base units, with a minimum of 50 cycles per unit. The units shall be monitored in such a way as to accurately record the total energy consumption per cycle. At a minimum, the following must be measured and recorded throughout the test period for each test unit Hot water usage in gallons, electricalenergy in kilowatt-hours, and the cycles of usage.Appendix B Curt Riechman Whirl pool

# Adaptive System Test Procedures Adaptive Control Systems

- 

## Test load size is linked to measured clothes washer capacity.

- 

## Manual Control systems require testing with max. and mm. loads.

- Adaptive control systems require max., mm., and average size loads, as a minimum and in some cases may require (2) additional test loads.

- 

## Procedures as defined are applicable to all clothes washers (i.e., HA,

## VA, compact, or standard)

- New Load usage Eactors are defined for products with adaptive systems. The LUF's for manual controlled products are unchanged.

- Adaptive systems not include any concept requiring soap, soil level detection, or other laundry aid products.

## Clothes Container Capacity Objective of Task Force: 1. Address whether dispensers or other removable parts are to remain in place. 2. Address void spaces which the clothes load would not occupy. 3. Remove confusion about sensor overrides. 4. Define a reasonable and safe water temperature to perform testing. Existing procedure suggests 1400F in density definition. 5. Provide density of water values to avoid potential confusion.

## Capacity

Objective #1: "Removable Parts" Addressed Verbiage employed: "All parts which occupy space within the clothes container and which are recommended for use with the energy test cycle shall be in place...." Objective #2: "Void Spaces" Addressed Verbiage employed: "... 

### and shall be lined with 2 mu, plastic sheet to prevent water from entering any void space." Objective #3: Remove "Sensor Override Confusion Removed "(This filling procedure may require overriding the fill level control, or manually completing the fill to the top of the container after the fill sensor terminates the fill at maximum level.)" Verbiage employed: "Fill the clothes container manually with

## Water & Energy Measurement

Task Force Objectives: Simplification. Measure Jjwater use, not just hot water. - Provide recognized procedure to total water usage measurement as requested by utilities and others. Encompass all existing clothes washer configurations and incorporate methods to test adaptive fill control technology. One wash/rinse temperature selection clothes washers. - Water heating clothes washers.

- 

### Electronic water temperature control clothes washers. Incorporate a cloth test load. - Size of load at minimum water level to be 3.0 pounds. - Size of load at maximum water level to correlate with measured clothes container capacity and a table provided for correlation. - Additional size loads required to be tested if an "adaptive fill control" is available. An "average load" size correlating to the measured clothes container capacity is also provided in the table with maximum and minimum test load sizes.

## Water & Energy Measurement

## Cont0

Simplification 1. Consider all washers as capable of providing a maximum wash water temperature at: (a) the test supply hot water temperature of 1300 F or less, or (b) greater than 130° F by internal heating. 2. Consider all washers as capable of providing wash cycles with wash water temperature termed as follows with cold rinses: COLD (The minimum available; typically, 60° F cold

supply water.) HOT (^ 130° F hot supply water.) WARM (Intermediate; between hot and cold.)

Can be a simple calculation rather than measurement if the one or multiple available selections are uniformly distributed between hot and cold. EXTRA HOT (> 130° F water available by internal heating.) 3. Account for availability of warm rinse option. 4. Provided a reference chart (Table 3.2) to aid testers in determining procedure test sections required to be followed for the configuration of the product being tested.

### Section 3.2.2: "Including hot and cold water wash, deep rinse, and spray rinse." Encompass Existing Conflirations Plus Adaptive Controls Section 3.2.3: Address Adaptive Controls Three (3) scenarios exist: 

### 1. Adaptive and manual control combination: a) test using adaptive; test using manual; average results; or b) use "field testtt procedure. 2. Adaptive controls which are completely self-determinate of proper water fill level: a) use adaptive procedure. 3. Adaptive controls which do not adaptively modify water fill levels: a) set fill to maximum level for maximum load size and average load size; b) set fill to minimum level for minimum load size. Section 3.2.4: Address Manual Controls 

### 1. Test maximum load with manually selected maximum fill level. 2. Test minimum load with manually selected minimum fill level. 3. No "averaget' load size tests required.

### Warm Wash Cycle 3.6 Cold Wash Cycle Procedures call out the following routine:

- 

### Test maximum load and maximum' water fill.

- 

### Test minimum load and minimum water fill. Test average load. - Check for linearity of adaptive fill system: • Calculate total water use @ maximum load. • Calculate total water use @ average load. • Calculate total water use @ minimum load. • Additional load sizes testing required if the measured total water use of the average load is different by 5% or more than a calculated average of the maximum and minimum load total water use.

Qualifiers exist regarding necessity to test warm cycle. Warm Wash: 1. No tests required if available selections are

uniformly distributed between hot and cold wash. 2. If distributed non-uniformly, test all intermediate selections and average the results.

Warm Rinse Procedures common to both non-water heating and water heating clothes washers:

- 

### Measure hot water consumption only of rinse.

- 

### Test the "hottest" rinse cycle available.

- 

### Includes deep and spray rinses.

- 

### Test maximum load size and maximum fill level.

- 

### Test average load size and fill level (if adaptive).

- 

### Test minimum load size and minimum fill level. Additional procedure unique to water heating clothes washers: - Measure the total electrical energy for a warm wash cycle and hottest rinse cycle: use maximum, minimum, and average (adaptive) load sizes. - Subtract the total electrical energy for the warm washcycle with cold rinse (previously determined in Section3.5) from the warm wash and hottest rinse cycle to obtain the additional electrical energy for warm rinse.

## 33% Warm Rinse Usage Considering all clothes washers, 20% of aU loads are rinsed in warm water. However, approximately only 60% of the total number of clothes washers have a warm rinse option avajlable.Therefore, the 20% warm rinse usage needs to be applied to only 60% of the machines. This will more accurately reflect how these machines are used by the consumer.

Since 20% is 1/3 of 60%, warm rinse is selected for 33% of the loads on machines which have warm rinse available. Total percent of loads rinsed
