PROJECT TOPIC: Construction and Fabrication of a Mobile Deep Freezer

Project Body:


CHAPTER ONE

INTRODUCTION

The main objective of this project is to construct and fabricate a deep freezer. The purpose of a deep freezer is to extract as mush heat from the cold body as possible with the expenditure of as little work as possible. In the refrigeration cycle, a substance called the refrigerant is compressed, cooled and then expanded. In expanding the refrigerant absorbs heat its surrounding (the cooling compartment) to provide refrigeration. After the refrigerant absorbs heat from the source, the cycle is repeated.
