This online engineering course provides necessary information to understand the principles and theory of refrigeration, the components of mechanical refrigeration systems, and the types of refrigerants and associated equipment. This course also discusses the methods used for installing, maintaining, and repairing refrigeration equipment, including domestic refrigerators and freezers.
Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.
This 8 PDH online course is intended for HVACR, mechanical and industrial engineers, manufacturers, maintenance staff, and others seeking a basic understanding of refrigeration systems.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the physics behind heat and refrigeration

This online engineering PDH course provides an overview of air compressor systems, their design, and the components that make up a system. It also provides the means of identifying and directing the proper construction techniques for installation of various components, as well as an understanding of the maintenance of previously installed systems.
Compressed air is a form of power that has many important uses in industrial activities. An air compressor plant is required to supply air of adequate volume, quality, and pressure at the various points of application. These plants or systems are classified as low-pressure, medium-pressure, or high-pressure systems.
This 2 PDH online course is applicable to mechanical engineers and other professionals who are interested in learning more about compressed air systems.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with the classifications of compressed air systems
- Understanding the air quality requirements
- Learning about the components of air compressors and the auxiliary equipment
- Knowing the different types of distribution systems
- Gaining an overview of the maintenance requirements associated with air compressor systems

This online engineering course presents the operational principles and basic mechanisms of the internal combustion engine.
The power of an internal combustion engine comes from burning a mixture of fuel and air in a small, enclosed space. When this mixture burns, it expands significantly; building pressure that pushes the piston down, in turn rotating the crankshaft. Eventually, this motion is transferred through the transmission and out to the drive wheels to move the vehicle.
The automobile is a familiar object to all of us. The engine that moves it is one of the most fascinating and talked about of all the complex machines we use today. This machine is what we call the internal combustion engine.
This 3 PDH online course is intended for mechanical and industrial engineers, designers, manufacturers and anyone interested in gaining a better understanding of the basics of an internal combustion engine.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the principles of operation, the different classifications, the measurements and performance standards of an internal combustion engine
- Identifying the series of events /cycles in a gasoline engine
- Identifying the series of events /cycles in a diesel engine
- Understanding the differences between a four-stroke cycle engine and a two-stroke cycle engine
- Recognizing the differences in the types, cylinder arrangements, and valve arrangements of internal combustion engines
- Identifying the terms, engine measurements, and performance standards of an internal combustion engine

This online engineering PDH course presents the principles of engineering ethics that every engineer is expected to live by when practicing their profession.
Engineering ethics is (1) the study of moral issues and decisions confronting individuals and organizations involved in engineering and (2) the study of related questions about moral conduct, character, ideals and relationships of peoples and organizations involved in technological development (Martin and Schinzinger, Ethics in Engineering).
This course describes the fundamental legal concepts with which very engineer should be familiar. It also presents unique disciplinary case studies selected from across the nation, as well as hypothetical ethical challenges that demonstrate how difficult it can be to apply the code of ethics for engineers.
This 2 PDH online course is applicable to all professional engineers who are either required to fulfill 2 PDH in engineering ethics or are interested in broadening their understanding of what it means to practice and uphold the honor and integrity of their engineering profession while holding the utmost safety, health, and welfare of the public.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the common definition of ethics regarding engineering
- Learning about the important principles of the engineer’s professional responsibility
