SkillTech: (HVACR) Cooling and Refrigeration Systems
Cooling and Refrigeration provides students with the opportunity to become proficient in the HVACR knowledge and skills as related to thermodynamic principles, the relationship of temperature and pressure, system components, refrigerants, service procedures (recovery/recycling, evacuation, leak detection, charging), metering devices, troubleshooting, and compressors. Students will be able to test for the Act 608 Technician Certification-Universal.
The course is 60 hours in length and students will be expected to acheive the following:
- Define and distinguish sensible heat, specific heat, latent heat, saturated conditions, superheat, and subcooling.
- Use various thermometers and pressure gauges to take accurate measurements of temperature and pressure and use a saturation or pressure-temperature (P/T) chart.
- Properly identify and explain the purpose of each component in a refrigeration system.
- Recognize and identify different refrigerants, azeotropic mixtures, and zeotropic blends.
- Properly perform recovery, recycling, leak detection, evacuation, and charging procedures.
- Install, adjust or size, and troubleshoot automatic expansion valves, thermostatic expansion valves, capillary tubes, and metering orifices.
- Identify, install, adjust, and troubleshoot hand valves, check valves, solenoid valves, EPRs, CPRs, hot gas bypass valves, head pressure control valves, and receiver pressure regulators.
- Identify the three basic compressor designs, describe the operation of each type of compressor, properly align pulleys and flywheels, and select, size, and replace V-belts.
- Select the proper lubricant for a system and add or remove the amount necessary.
- Interpret and use information from compressor data plates.
- Explain the operating principles of various types of chillers and absorption refrigeration systems.
- Earn Act 608 Technician Certification-Universal.
- Understand customer service skills.
Hands-on activities are an integral part of this course.
