Evaluation of Freezing Capacity of a Conceptual Adaptive Food Preservation System (AFPS) Appliance in the Context of IEC 62552 Standards

Preserving food item individually in an Adaptive Food Preservation System (AFPS) package is a new concept. Before completing a product commercialization process, AFPS packages must be certified against mandatory standards like IEC 62552. This paper evaluates two key aspects of energy efficiency against the IEC standard. Internal volume and storage capacity are evaluated qualitatively. Freezing capacity will be evaluated by experimentation with a simulated AFPS package. The result is verified by an analytical model. Error source and rectifications are identified. The usable storage capacity with AFPS packages is larger than that in a typical refrigerator if both have the same internal volume. Experimentation and theoretical model analysis have demonstrated that the freezing times are 3.18 and 3.32 hours, respectively, which can be considered agreeable. The freezing capacity of the conceptual AFPS package is found to comply with the IEC standard.
