Plumbing Recovery and Reclaiming (40 Hours): In this unit, students will describe ozone depletion and global warming, differentiate between CFCs, HCFCs, HFCs, and HCs, and discuss popular refrigerants and their applications. Discuss refrigerant blends and how temperature glide and fractionation applies to it. Students will discuss refrigerant oils and their applications, define the terms recover, recycle, and reclaim, and describe the methods of recovering, including active and passive methods.
Fundamentals of Hydronics (40 Hours): In this unit, students will explain three ways in which heat transfers into a structure. Students will be able to list the different types of evaporator coils, and identify the different types of condensors.
Heating and Humidification Systems (30 Hours): In this unit, students will discuss the efficiency and relative operating costs of electric heat, list the types of electric heaters and state their uses and describe how sequencers operate in electric forced-air furnaces. Students will trace the circuity in a diagram of an electric forced-air furnace, perform basic tests in troubleshooting electrical problems in an electric forced-air furnace and lastly, describe typical preventative, maintenance procedures used in electric heating units and systems.
Hydronics and Measurements (30 Hours): In this unit, students will describe the characteristics of the propeller and centrifugal blowers, take basic air pressure measurements and measure air quantities. Students will list the different types of air measuring devices, describe the common types of motors and drives and describe various duct systems.
Heat Pumps and Controls (30 Hours): In this unit, students will explain the function of the 24-V control voltage and explain the operation of the high- and low- pressure controls. They will describe the space thermostat, the compressor contractor and how crankcase heat is applied in some modern equipment. They will identify operating and safety controls and compare modern and older control concepts.
Service and Troubleshooting (30 Hours): In this unit, students will calculate the correct operating suction pressures for both standard – and high efficiency hydronics equipment under various conditions and calculate the standard operating discharge pressures at various ambient conditions. Students will select the correct instruments to troubleshoot electrical problems in hydronics systems, check the line- and low-voltage power supplies, and troubleshoot basic electrical problems in a hydronic system.
Fundamentals of an Estimator (60 Hours): Students will understand the role of an estimator. They will be introduced to the role of an estimator and learn what basic assistance they will be providing in a junior position; rom calculating various statistical data to researching historical data. Students will be exposed to a full estimating procedure from start to finish. This module will also review necessary mathematical skills for the estimating sector
Estimating and Takeoffs (60 Hours): In this course students will learn how to calculate various statistical data, quantity takeoffs, material price list, labor costs, and equipment. They will learn how junior estimators assist with obtaining scopes of work and pricing from sub-contractors and suppliers. Students learn how to make estimates and take-offs from all sources of material, blueprints, manual drawings and electronic simulations.
