Refrigeration Systems (IPO)

The refrigeration cycle is used in many different applications to transfer heat from one fluid to another. One common application is to provide cooling in HVAC systems. This interactive online course discusses the theory, equipment, and processes related to the vapor-compression refrigeration cycle.

Did you know many refrigerants are harmful to human health and/or the environment? In air conditioning and refrigeration systems, the refrigerant is the substance that circulates through the equipment, transporting heat from one area to another. This interactive online course covers how to execute a refrigerant management program to be compliant with AHJ requirements, identifies EPA Regulations, and describe record keeping requirements.

The compressor is the element that represents the heart of the refrigerant circuit. Its purpose is to create, maintain and control the flow of refrigerant inside the refrigeration circuit, drawing in gas refrigerant at low pressure and low temperature, and delivering it at a higher pressure and temperature.

Care must be taken to insure compatibility among refrigerants, oils, and system components. This course will discuss refrigerant safety, types of refrigerant, and how refrigerant is used.

Copper tubing is generally used for plumbing, heating, and refrigeration systems. It has good thermal transfer characteristics, is easily bent and fabricated, is harder than aluminum, and is easier to join than aluminum. This course will discuss the piping and valves used in refrigeration systems.

There are four main components in a mechanical refrigeration system: the compressor, condenser, liquid refrigerant, and evaporator. This course will discuss each of these components and their purposes.

Troubleshooting of any type of refrigeration unit depends, in part, on your ability to compare normal operation with that obtained from the unit being operated. Obviously for you to detect these abnormal operations, you must first know what normal operation is. This course will cover common issues in refrigeration systems and how to perform routine maintenance.

The ideal refrigeration cycle involves several stages. This course will discuss each of these stages and the equipment that is involved in each stage.
