Refrigerator/Freezer

The refrigerator/freezer configuration chosen was a side by side configuration with a built-in ice maker and a cold water dispenser. The location should be away from closed spaces such as corners and other large appliances. Additional data can be found in the following subtopics.

Refrigerator

Accessibility is the biggest problem in laying out the location and designing the refrigerator. Due to the tight seal and weight of the refrigerator doors, a significant force and space is required to open and close them. It is best to place it in an open area away from corners and any other obstructions. Large loop handles should be provided for accessibility. If possible a self opening and closing feature is a good idea for disabled individuals with loss of strength and motor coordination. This can best be accomplished with electrical servo motors with a touch sensitive switch.

Dimensions
Height
48 inches is the maximum height a wheelchair assisted individual can reach.
Width
32-48 inches; Standard to extra wide dimensions are recommended. Due to a lower height of the refrigerator it might be necessary to widen it to allow plenty of storage space.
Depth
Standard dimensions are best used if all drawers have a rollout basket feature. This seems to be the best alternative since storage space is lost due to height limitations.

Adaptive Features
Location
The best alternative is to position the refrigerator away from the corner of the kitchen so doors open 135 degrees. This allows plenty of space to open the doors and wheelchair accessibility to the refrigerator.
Loop handles
Loop handles should be the same dimensions as handrails, 1 and 1/4 to 1 and 1/2 inch diameter for the hand grip and they should be mounted 1 and 1/2 inches away from the refrigerator door. These are excellent features for adaptive to degraded motor coordination and visually impaired individuals.
Rollout basket shelves
Due to standard depth of the refrigerator, the reach must be accomodated for wheelchair assisted individuals. Simple plastic covered wire baskets with wheels on a rail, allows access to the rear of the refrigerator. A lock-in mechanism should be designed into the shelf at it's maximum extension which should be set at 2/3 of it's depth.
Side by side layout of Refrigerator/Freezer
The best configuration is for the two units (refrigerator/freezer) to sit side by side with their doors opening towards the middle. This allows the wheelchair to pull up next to the refrigerator with the door opening away from the indivdual allowing maximum access. This feature adapts to limited reach. The drawback is that it is difficult to move items from refrigerator to freezer or vice versa.



Freezer

Freezers are identical to refrigerators in trying to achieve design goals for adaptibility to disabled individuals. Accessibility is the main objective in designing a successful unit with automation being the next most important goal.

Dimensions
Height
48 inches is the maximum height a wheelchair assisted individual can reach. This height also matches the refrigerator height sitting next to the freezer.
Width
32-42 inches; Standard dimensions are recommended. Freezers don't require as much space as refrigerators but an ice maker/dispenser takes up a significant amount of space.
Depth
Standard dimensions are best used if all drawers have a rollout basket feature. This seems to be the best alternative since storage space is lost due to height limitations.

Adaptive Features
Location
The best alternative is to position the freezer away from the corner of the kitchen so doors open 135 degrees. This allows plenty of space to open the doors and wheelchair accessibility to the freezer.
Loop handles
Loop handles should be the same dimensions as handrails, 1 and 1/4 to 1 and 1/2 inch diameter for the hand grip and they should be mounted 1 and 1/2 inches away from the freezer door. These are excellent features for adaptive to degraded motor coordination and visually impaired individuals.

Frostless Freezer
This is a must to eliminate maintenance and provide as much automation as possible for disabled individuals.
No ice tray provided

Ice/water dispenser

Adaptive Features
Location
Built into freezer at 32 inches level (average counter top height for wheelchair assisted individual)
Ice maker
Eliminates the nuisance of filling up and emptying ice trays for mobility impaired individuals. Location of ice maker should be next to water dispenser.
Plumbing
The ice/water dispenser requires a cold water line and piping for drainage; The four different materials pipe can be made from is copper, cast iron, steel and plastic (PVC). Copper is the most expensive but lasts the longest due to lack of corrosion. It's light, easy to install and can be easily cut with a hacksaw. Drain pipes are generally thinner than hot and cold water pipes. They require venting so the sewer gases do not filter back into the house. Copper pipe is recommended and it's available in four wall thicknesses shown in Table 1. Type M is recommended for cold water and type DWV for drain pipes. Silicon strip tape is recommended for copper piping threads to provide ease of maintenance for future pipe replacement.

Type Common Use
K Underground water services (Thickest wall)
L Natural gas services
M Residential water systems (Thiner wall)
DWV Drain pipes (Thinnest wall)
