HVAC 205 - Heat Pump Systems

PREREQUISITES: HVAC 101 - Heating Fundamentals  and HVAC 103 - Refrigeration I , and INDT 113 - Industrial Electrical I  or BCTI 130- Introduction to Electrical.
PROGRAM: Heating, Ventilation, and Air Conditioning
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019

Familiarizes students with the refrigeration cycle as it applies to the heat pump system and the different types of heat pump systems. Covers procedures used to diagnose electrical, control, mechanical and refrigeration problems common to heat pumps. Includes sizing of heat pumps, specialized heat pump refrigeration components and electrical controls, the air-to-air heat pump defrost cycle, and schematic and pictorial diagrams. 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:

  1. Demonstrate safe practices and procedures.
  2. Interpret and utilize pictorial and schematic diagrams.
  3. Identify different types of heat pumps in relation to their source of heat.
  4. Diagram refrigerant flow through a heat pump in both the heating and cooling mode identifying refrigerant condition and pressures.
  5. Explain in detail the defrost cycle of the air-to-air heat pump.
  6. Identify and troubleshoot electrical control system components covered in this course.
  7. Identify and troubleshoot common refrigeration system components covered in this course.
  8. Explain the different methods for checking refrigerant charge and charging heat pumps covered in this course.
  9. Describe the typical thermostats used with heat pumps.
  10. Explain the need and types of auxiliary heat.
  11. Given the heat loss and heat gain of a structure, size a heat pump and back-up electric heat.
  12. Outline typical heat pump control technique.
  13. Compare and contrast the different types of heat pumps: air-to-air, ground source and closed-loop water source heat pumps.
  14. 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.
