Increasing the product storage temperature from 0° F to 5° F indicates that the cost of energy could be reduced by approximately 7.5 percent, he said. The magnitude of energy savings would also be influenced local costs of electrical energy.
The opportunities for cost savings through elevation of refrigerated warehouse temperature for frozen foods are tempting, he noted, but they must be evaluated in contrast to the potential losses in product quality.
The dependence of frozen food shelf-life on storage temperature varies with the type of product, as some products are more sensitive than others.
The magnitude of the savings in energy cost, concluded Heldman, will depend on external environment temperature and local electric energy cost, as well as other operating conditions at the warehouse.
