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:

Describe heat pump operation, including the refrigeration cycle and heat transfer processes.
Identify key system components in both air-source and water-source heat pumps.
Assess the impact of airflow issues on system performance.
Describe the sequence of operations of the heat pump defrost cycle.
Analyze the heat transfer cycle in both air-source and water-source heat pumps.
Troubleshoot common electrical, mechanical, and airflow issues in heat pump systems.
Evaluate the refrigerant charge of a heat pump system.
