The HVACR 3D training package helps users develop highly desired cognitive skills while providing students and practicing technicians with a mechanism to safely learn and practice the processes and procedures directly related to the servicing and troubleshooting of commercial refrigeration systems.

Being accessible from anywhere, with a computer, smartphone or tablet, students can learn at their own pace, or reinforce what they learn in class, creating the perfect platform for any blended educational environment. Here are some key features of this six-module program:

• The 6 modules are delivered one at a time, with each new section being unlocked as the previous section is completed. This feature ensures that the program is completed as intended.
• Each module consists of a mentor feature which guides the learner through each process. They say that practice makes perfect, but this is not necessarily true. If you don’t practice correctly, you cannot possibly learn correctly. This feature makes certain that users practice correctly.
• After the mentor section has been successfully completed, the program allows users to practice, and master, the procedure on their own.
• At the end of each module there is a knowledge check. The knowledge check for each module must be completed before the next module can be unlocked.
• Within the subscription period, users have the ability to go back and review any completed modules as many times as desired.
• A completion certificate and feedback section will open after the final quiz is completed.
• There is a leaderboard feature which allows users to post their scores publicly, if desired.

Learning Objectives for the HVACR 3D Training Course

Upon completion of this course, you should be able to demonstrate knowledge of the following procedures:

Module 1: Gauge Manifold – Installation and Removal

• Demonstrate how to properly install a gauge manifold on a system with service valves to minimize the loss of refrigerant and to prevent system contamination.
• Demonstrate how to properly remove a gauge manifold from a system with service valves to minimize the loss of refrigerant and to prevent system contamination.

Module 2: Standing Pressure Test

• Demonstrate how to prepare a system with service valves for a nitrogen standing pressure test.
• Demonstrate how to perform a nitrogen standing pressure test.
• Demonstrate how to verify that a system with service valves is leak free by interpreting the results of a nitrogen standing pressure test.

Module 3: Evacuation and Holding Charge

• Demonstrate how to prepare a system for evacuation.
• Demonstrate how to evacuate a system with service valves.
• Demonstrate how to evaluate the vacuum level in a system.
• Demonstrate how to properly add a holding charge to a properly evacuated system.

Module 4: Charging

• Demonstrate how to calculate condenser subcooling.
• Demonstrate how to properly charge a system with service valves and a receiver using the sight-glass and subcooling method.

Module 5: Recovery

• Demonstrate how to prepare a system for recovery
• Demonstrate how to properly recover refrigerant systems with service valves to minimize the release of refrigerant to the atmosphere.
• Demonstrate how to evaluate the refrigerant recovery process.
• Demonstrate how to properly add a holding charge to a properly evacuated system.

Module 6: Exam

• Demonstrate that adequate knowledge has been retained throughout this program
