EcoFridge Saves Time and Energy

In their New Product Development class, a team of UC Berkeley graduate engineering students were challenged to develop a cost-competitive, environmentally friendly refrigerator. The Berkeley team was paired with a group of industrial designers from the Universidad Nacional Autónoma de México and Mabe, an Mexican appliance manufacturer.

Project Title: 
EcoFridge
Project Designers: 
- UC Berkeley: Vince Romanin, Daniel Talancon, Tarek Hosny, Dave Lettieri - Universidad Nacional Autónoma de México: Nicole Alcántara, Mitzy Orea, Alfredo Mariscal, and Arturo Ramirez - Designed for Mabe
Project Date: 
Dec 2011
Student
EMA-Fridge

 

By analyzing the lifecyle environmental impacts with the Autodesk Eco Material Adviser, the team realized that reducing energy use was the most effective way to improve environmental performance.

But through user research, the team realized they needed to focus on user’s needs for economy, good aesthetics, and ease of use. To be a viable product in the Mexican market, it was especially important that any environmentally friendly technologies be affordable for both the company and the user.

The student’s final design features a quick access tray that allows people to access the food they use most without opening the full door and an insulated window that allows you to see inside the fridge. Its adjustable shelves and large vegetable tray also makes it easier to organize and access the food.  All of this keeps the fridge closed longer, which saves energy by preventing the cold air from escaping.

To save more energy, the team also used innovative phase change material that acts as a thermal battery. By only running the compressor to “charge” the battery at night, when electricity rates are low and ambient temperatures can be cooler, the fridge can stay cold all day while saving money for the end-users. The team estimates that this design could reduce energy use by 40%.

To communicate their final design, the team created an interactive 3D model and animated exploded drawings using Autodesk Inventor Publisher (download it below).
