FLUSHING OF THE CONDENSER
The refrigerant gas let into the condenser through the compressor and the vacuum pump was connected to the condenser to absorb dirty.
REFILLING OF GAS INTO THE COMPRESSOR
Gas was refilled into the compressor due to shortage of gas and it was filled inside the charging value and refrigerant.
CHANGING OF DRIVER STRAINER DUE TO BLOCKAGE
The driver strainer was change due to blockage with the help of oxygen and acetylene welding.
SPRAYING OF THE FRIDGE
The compressor was put on and the compressed air through the holes to the gun due to high pressure inside the tank. The air then forces the point out of the gun for spraying.
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.
SCOPE
The scope of this project was limited to maintenance and repair of a faulty refrigerator. This report is basically comprised of all arrive at a proper and safe working conduction of a faculty refrigerator.
