The refrigerator is an essential part of almost every household for preserving food and thereby reducing wastage. The primary function of a refrigerator or freezer is to provide food storage space maintained at a low temperature for the preservation of food. Its essential secondary function is the formation of ice cubes for domestic consumption. A storage temperature of 0° to 4°℃ (32° to 39°F) is satisfactory for the preservation of most of the fresh foods. For the short-term storage of frozen foods, however, temperatures much below the freezing point are required. The evaporator in the domestic refrigerator, formed as a box, serves as a freezer for the storage of frozen food as well as for making ice cubes. It is mounted above the food storage space. Pictorial representation of commonly used single door domestic refrigerator has been mentioned below: Cold vapour Ice box Heat flows into vapour Vapour loses heat in pipes outside refrigerator Pump circulates vapour through pipe As an embedded engineer, design an embedded system for the refrigerator unit to meet the requirements of a domestic user. Provide the details of the designed embedded system in following format: a. Detailed hardware block diagram for the embedded system. b. Detailed software flowchart for the operation of the embedded system. c. Choice of an appropriate microcontroller with justification.
