This study investigates the energy savings capability and potential of ultra-low temperature freezer monitoring systems when used as an energy consumption diagnostic tool. Ultra-low temperature (ULT) freezers are common in university labs and facilities involved in research and development requiring the storage of sensitive materials such as pharmaceuticals and cultures. These ULT freezers often maintain temperatures as low as -80°C, thus consuming large amounts of energy. Reports estimate that the average ULT freezer uses about 6,400-9,300 kWh per year. Identifying energy savings opportunities in the ULT freezer market could prove highly beneficial to utilities, consumers, and the public.
