AHR 114 Heat Pump Technology

Lecture: 2 Lab: 4 Clinic: 0 Credits: 4
This course covers the principles of air source and water source heat pumps. Emphasis is placed on safety, modes of operation, defrost systems, refrigerant charging, and system performance. Upon completion, students should be able to understand and analyze system performance and perform routine service procedures.

Pre-requisite(s): AHR 110  or AHR 113 .
Course is typically offered in Spring.
Student Learning Outcomes (SLOs)
At completion of the course, the student should be able to do the following:

  1. Connect refrigerant gauges to a heat pump on a given assignment.
  2. Identify the sequence of operations of the defrost cycle on a written test.
  3. Perform a prescribed function test of the defrost controls in a given assignment.
  4. Use the refrigerant scale to weigh in refrigerant charge in a field setting.
  5. Create a refrigerant distribution log book in a given project.
  6. Characterize the heat transfer cycle on a water source heat pump in a field setting.
  7. Calculate the performance of a system in a field setting.
