HVAC 171 - Hydronic Heating Systems
PREREQUISITES: HVAC 101 - Heating Fundamentals .
PROGRAM: Heating, Ventilation and Air Conditioning
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019
Students learn the basic components of a hydronic radiant heating system; types of boilers, distribution systems, heat emitters and controls. Students study the properties of water and its use as a heat transfer fluid. Through the use of Radiant Design Software programs, students will learn about the unique elements of heat loss calculations when using radiant heating and will design a radiant heating system for a residential/light commercial building. This course will use lecture, lab and online simulation to prepare students for the nationally recognized certification exam as part of the outcome assessment learning objectives.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Demonstrate the ability to correctly identify various types of boilers, heat emitters, controls and piping components.
- Demonstrate the ability to lay out radiant piping systems.
- Become proficient in the use of design software.
- Determine required system flow rates based on total dynamic head of a piping system.
- Understand proper pump sizing through the use of pump performance curves.
- Estimate materials required for a residential / light commercial radiant heating system.
- Describe various control / mixing strategies to produce different supply water temperatures.
- Describe outdoor reset and its applications.
- Practice soldering and press-fit pipe joining methods.
- Measure Delta P and Delta T on an operational hydronic heating system.
- Troubleshoot common system problems related to flow and entrained air.
- Attain readiness to take the ESCO HVAC Excellence Employment Ready exam.
CERTIFICATION STATEMENT:
Ivy Tech cannot guarantee that any student will pass a certification or licensing exam. Your success will be determined by several factors beyond the instruction you are given in the classroom including your test-taking skills, your willingness to study outside of class, and your satisfactory completion of appropriate practice exams. Certification and licensure exam questions are drawn from databases of hundreds of possible questions; therefore, a thorough understanding of the subject matter is required. Ivy Tech’s coursework is designed to assist you in understanding the material sufficiently to provide a firm foundation for your studies as you prepare for the exam.
