Reciprocating compressor also known as a piston compressor is a positive displacement device. It is one of the most widely used types of compressor in which gas is compressed by reciprocating motion of a piston. It handles low mass of gas but high pressure ratio. During the operation of reciprocating compression, it takes a large amount of gas from the suction line, it is then get compressed by the reciprocation motion of piston driven by the crankshaft, and then it discharges the compressed gas to the discharge line. The main aim of this study is to fabricate a reciprocating compressor with , a reciprocating compressor with cylinder length = 57mm, piston diameter of 60mm and cylinder diameter of 80mm was fabricated. The result of this work indicates that the machine more efficient than the conventional compressors.

CHAPTER ONE
1.0 INTRODUCTION
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. A compressor is also a device that converts power (using an electric motor, diesel or gasoline engine, at c) into potential energy stored in pressurized air (that is compressed air). There are basically 5 types of air conditioner compressor that are commonly used in the HVAC industry and are;
- Reciprocating
- Scroll
- Screw
- Rotary
- Centrifugal
1.1 BACKGROUND
The reciprocating air compressors are found in places where low flow rate and high pressure of the gas are required. These compressors are used primarily for filling the vehicles tire air, small paint jobs, commercial purposes, dust cleaning, hand tools, etc.
1.2 PROBLEM DEFINITION
Before the invention of other compressors like the reciprocating compressor, generation of pressure was lower, high efficiency of operation was not achieved. Thus, there was a big need for the use of a reciprocating compressor having a piston that aids in higher pressure generation and higher efficiency.
1.3 AIM OF PROJECT
The main aim of this study is to design and fabricate a reciprocating type of compressor for mechanical engineering department.
1.4 OBJECTIVES OF PROJECT
The objectives of the project are:
- To design the components required for this machine.
- To design the machine that is cost effective and easy to handle.
- To overcome the low efficiency seen in other types of compressors.
Its process of operation is faster and reliable. Air is a free gift of nature which is used as the working fluid and in essence, it saves cost. They are also capable of giving large pressure ration.
1.6 SCOPE / LIMITATION OF PROJECT
The scope of this work covers fabricating a reciprocating type of a compressor. The mechanism of the machine can be used to convert any rotational input to a translational output motion.
In this study, a reciprocating compressor with cylinder length = 57mm, piston diameter of 60mm and cylinder diameter of 80mm was fabricated.
1.7 APPLICATIONS OF RECIPROCATING COMPRESSOR
Reciprocating compressor used to produce high-pressure gas output. Reciprocating compressor is mainly used in the refrigeration cycle. It is widely used in oil refineries, gas pipelines, natural gas processing plants, chemical plants, etc. it is also used in blowing of the plastic bottle.
1.8 ADVANTAGES AND DISADVANTAGES OF RECIPROCATING COMPRESSOR
Advantages
- Used to produce high-pressure gas.
- It can compress gases and refrigerant of a wide range of molecular density.
- High efficiency and flexibility.
- Cheap and rugged design.
Disadvantages
- One of the drawbacks of the reciprocating compressor is that it cannot self-regulate its capacity against a given output pressure, it will continue displacing the gas until told not to do.
- The size of compressor is very large for a given capacity.
- Part of the work input is lost due to frictional resistance between the piston and cylinder.
- Pulsating of fluid flow. The operation can be made smooth by using a flywheel.
- High vibration and noise.
