Abstract

Deepfreeze is a large home appliance that keeps its contents just below the freezing temperature. Freezers are electric and can be plugged into a standard household receptacle. A freezer is used for storing and extending the life of certain foods. There are various freezer capacity sizes on the market.  Freezer units are used in households and in industry and commerce. Food stored at or below −18 °C (0 °F) is safe indefinitely. Most household freezers maintain temperatures from −23 to −18 °C (−9 to 0 °F), although some freezer-only units can achieve −34 °C (−29 °F) and lower.
The need for an authentic and reliable report relating to the design and construction of 80cm x 70cm x 50cm mobile deep freezer is inevitable. It should be a top priority of every individual in order to avoid huge expenditure in purchase to foreign ones. Its for this reason that this report is written for the benefit of those who are privilege to design and construct their own deep freezer for used.
This report is base on ordinary and advanced level research, in order to aid easy reading and understood for an average person.
This report is divided into chapters, which discussed extensively, the introduction of mobile deep freezer, the introduction of mobile deep freezer, the history the practical refrigeration cycle with full attention given to design factors, working principle and choice of materials. The method use in fabrication, assembly and knowing the safety requirement. Subsequently, advanced information pertaining calculation about the project have been given in certain section of this report which will be beneficial to those interested in the design and construction of 80cm x 70cm x 50cm mobile deep freezer.
