Product Description and Principal Function(s)

Celsius is a modular refrigerator that is configured by the user. A touch-sensitive control panel on the door of each cabinet, which includes five temperature presets, gives users the ability to store food correctly, maintaining freshness and storage lifetime. Full-extension drawers to waist height and pantry-style cabinets at the top allow for optimal space usage and usability, while still using the same footprint as a conventional refrigerator. Custom inserts provide for fruit, vegetables, meat & fish, dairy, bottles & jars, pantry and wine as well as optional shelf space. Users can purchase cabinets according to their changing needs.

Why does the product represent design excellence and why do you believe it deserves an Australian Design Award?

Celsius brings professional food storage to the home, essential for good health and minimal food wastage, by separating foods and creating a hygienic and convenient storage environment. Although it is a firm staple in our homes, our interaction with the refrigerator hasn't changed much since it became available on the domestic market almost 100 years ago. While conventional refrigerators hide food away where it can be easily forgotten about, Celsius displays food through double-glazed and tinted doors.The design reveals an understanding of our changing, busier lifestyles, our pride in our homes, and the richness and increasing diversity of food available to us.

The user is able to purchase units according to their unique needs, creating not only a customised refrigerator, but also optimising the usable space within it.

To operate, the user simply selects one of five temperature presets on the door. The cabinet is automatically set to the required value but can also be tweaked using the plus and minus function. The temperature is displayed on an LCD screen, which not only helps the user to monitor and locate food items, but also fosters an awareness of correct storage conditions.

Cabinets are finished in black satin, making the leap from domestic to professional, and differentiating the product within the marketplace. Furniture-style design features give Celsius a seamless fit within the kitchen and living room environments, including adjustable feet, which locate into the cabinets, recessed handle grooves and streamlined glass panels, also allowing for easy cleaning and maintenance.

The modular arrangement of Celsius makes it easier to move than a conventional refrigerator. Each cabinet includes silicone rubber hand grips that aid in the transportation and configuring of the product.

In order to maintain efficiency and standards, each cabinet is manufactured according to current practice. Cabinets are assembled from 0.5mm Cold Rolled Coil Steel with Polyurethane insulation. The compressor, condenser and evaporator coils as well as heat sinks are located in the base unit. The system includes an adaptation of existing airflow technology. Supply and return of refrigerated air takes place in the two airstream pipes located at the back of the refrigerator, each containing a system of fans, which create a forced airflow, drawing on refrigerated air generated by the base unit. A baffle in each cabinet opens and closes to regulate airflow and temperature inside the refrigerated space. A thermocouple located in the wall of each cabinet senses a rise or drop in temperature, relays to the CPU, which sends a charge to a bellows, which compresses or expands, pulling the baffle open or closed, depending on the temperature requirement.

Celsius allows users to customise their living spaces, particularly for smaller townhouses, units and apartments, by using the same footprint as a conventional refrigerator, whilst storing and displaying food for its true worth and role in our diets, enjoyment and health.
