CHAPTER ONE

INTRODUCTION

       Refrigeration is a science which deals with the process of reducing and maintaining the temperature of the mechanical appliance which caries out the refrigeration principle as in transferring heat from a cold reservoir to a hot reservoir and requires a work input. However this heat flow is transmitted through a medium. Heat is transmitted by conduction convention are extensively adopted in refrigeration.

 

PURPOSE:

       The purpose of this project work is simply to acquire a general knowledge in the maintenance of refrigeration equipment such as cold rooms refrigeration e.t.c.

       In the course of this project, we worked on a faulty refrigerator at Engr. Ayogu’s office.
