Course Descriptions

Mechanical Systems I


Study of water conveyance within residential construction, with emphasis on the selection and application of tools and materials appropriate for code approved system installation and operation. Additional topics include the study of dynamic and static forces impacting fluid transfer, introductory plan and specification development, and basic material and cost estimating. (Formerly PLH 111) 5 Credits (3 Lecture - 6 Lab)

Mechanical Systems II


Advanced pipefitting, fluid mechanics, and thermodynamics as they apply to fluid conveyance within commercial, institutional, and industrial applications. Emphasis on the selection and application of tools and materials appropriate for code-approved system installation and operation. Additional topics include fluid transfer mechanics, thermodynamic principles, ADA compliance, advanced plan and specification development, and material with cost estimating. (Formerly PLH 121) 5 Credits (3 Lecture - 6 Lab) Prerequisite(s): PLH112 or PLH111. Spring Only.

Mechanical Systems Lab Practices


Application of mechanical system concepts through on- and off-campus mechanical system construction projects. Students advance their trade experience and knowledge with real-life, practical, hands-on rigors. Course work includes continued study of plan reading and drawing, material and equipment selection and specification, system layout and installation, appliance start-up and operation, and utility maintenance and service performance. Actual job and material cost estimating is essential. Field trips to industry and product vendor demonstrations may be included. 3 Credits (0 Lecture - 9 Lab) Prerequisite(s): PLH112. Spring Only.

Piping and Mechanical Applications


Focus on skills needed in proper piping applications for fluid and gas transfer. Development of sound structural piping systems using appropriate materials such as copper, plastic, and iron. Topics include fitting selection, thermal transfer, pressures, state of matter, rate of movement, flow restriction and friction loss. (Formely RET214) 3 Credits (2 Lecture - 3 Lab) Fall Only.

Solar Thermal Systems


Continued study of mechanical heating systems and piping skills, focusing on the sun as a source of heat, mechanisms of transferring this heat to the building, and the equipment needed to accomplish this. Installation and maintenance of both passive and active solar systems, plus domestic water and space heating systems, are included. (Formerly RET222) 4 Credits (2 Lecture - 6 Lab) Prerequisite(s): PLH214 or RET214 or PLH112. Spring Only.

Fundamentals of Heating Systems


Basic concepts and functions of applied commercial building and industrial facility heating systems. Students from various technical backgrounds merge common knowledge and gain exposure to the specifics of identity, application, and operation of steam and hydronic boilers, pumps, warm-air furnace units, and fans/blowers. Topics focus on the importance of heating systems for comfort and process, types of systems, how each system works, identification of heating system components, the principles of water and air transfer, an overview of applicable ASME and NFPA codes/standards, equipment and operating safety controls and introductory control point strategies. 3 Credits (2 Lecture - 3 Lab)

Basic Heating Systems (Installation)


Theory and lab assignments on the installation and troubleshooting of gas fired hydronic heating systems, setting and piping of gas fired boilers, and installation of different types of hydronic heat emitters. Course work also includes the installation of different types of hot water piping system, such as series loop, and one and two pipe systems; an introduction of the theory and installation of radiant heating, secondary circuits, and hot water injection; and repair and operation of natural gas piping, boilers, flue gas analysis and combustion efficiency testing. (Formerly PLH 239) 3 Credits (2 Lecture - 3 Lab) Prerequisite(s): PLH111 or PLH112. Corequisite(s): PLH238.

Basic Heating Systems (Heat Loss Calculation and System Design)


Basic entry-level skills required to calculate heat loss and to design and layout various residential hot water central heating systems. Students design and layout gas hydronic heating systems using several different methods. (Formerly PLH239) 2 Credits (1 Lecture - 3 Lab) Prerequisite(s): PLH112. Corequisite(s): PLH236.

Hydronic Heating Systems


Basic entry level skills required to identify, install and operate residential and commercial steam heat systems, boilers and trim. Emphasis on combustion efficiency testing, and oil and natural gas burner service, installation and repair, and pipefitting skills. 4 Credits (2 Lecture - 6 Lab)
