Centrifugal chillers are used in medium- and large-sized buildings to provide comfort cooling. Many of them use the vapor compression refrigeration cycle, including centrifugal compressors and plate-and-frame or shell-and-tube heat exchangers, to produce chilled water that can be pumped to AHUs and FCUs located in different spaces throughout the building. At each AHU or FCU, the chilled water passes through a cooling coil while a fan blows air over the coil to produce cool air for the enclosed space. The chilled water then returns to the chiller unit, where it is re-cooled, and the process is repeated. Like other building systems, chiller systems require regular monitoring and maintenance in order to maintain their capacity and efficiency and avoid costly breakdowns and repairs. However, issues and breakdowns still occur. A good understanding of chiller design and operation is critical when troubleshooting a chiller system. This course discusses some common issues for centrifugal chillers and the troubleshooting steps and techniques that can be used to diagnose and determine the cause if a problem occurs.

Type I certification requires that technicians know how to safely and properly evacuate refrigerants from “small appliances” containing 5 pounds or less of refrigerant using the appliance’s compressor, system pressure, or self-contained recovery equipment. This interactive online course will cover these evacuation procedures, as well as how to deal with contaminants in a system and safety considerations.

In air conditioning (AC) and refrigeration systems, the refrigerant is the substance that circulates through the equipment, transporting heat from one area to another. Refrigerants must be handled and used carefully as many of them present hazards to the environment and human health. This interactive online course discusses safe methods of working with refrigerants and refrigeration systems.

Did you know HVAC and Refrigeration technicians who maintain, service, repair, or dispose of medium, high, and very high pressure appliances containing more than five pounds of a controlled refrigerant must pass the EPA’s Section 608 Type II certification exam? Type II certification requires that technicians understand several topics related to these systems, including leak detection, leak repair, evacuation requirements, recovery techniques, refrigeration, and safety. This interactive online course will cover the appliances included in the EPA Section 608 Type II certification exam, explain the techniques that are used to recover refrigerants, list evacuation requirements, and cover safety considerations for working with or around refrigerants, recovery equipment, and HVAC and Refrigeration systems.

Did you know Type III appliances differ from Type II appliances in that they operate in a vacuum on their low-pressure sides and sometimes on their high-pressure sides, which affects what happens when they develop a leak? When a Type III appliance develops a leak in a location that is under vacuum, air and/or moisture leaks in. In this interactive online course, we will cover the EPA 608 Type III certification exam, the techniques that are used to recover refrigerant, evacuation requirements and safety considerations for working with or around refrigerants.

In the vapor-compression refrigeration cycle, a “refrigerant” alternately absorbs and rejects heat as it circulates through four components – an evaporator, compressor, condenser, and metering device – changing pressure, temperature, and phases along the way. This interactive online course discusses different types of refrigeration systems and their components. It also discusses metering devices, compressors, and non-condensable gases.

Did you know the most common method of refrigeration is the vapor-compression refrigeration cycle? Refrigeration systems are used in many different applications to transfer heat from fluid in one area to fluid in another area, where the term “fluid” can refer to a liquid or gas. This interactive online course covers the three laws of thermodynamics, the operation of the four components of a basic refrigeration system, thermal energy transfer, and the maintenance procedures to maintain equipment efficiency.
