ECTC 201 - Refrigeration II (3,6) 5 Credits
Prerequisite(s): ECTC 101 - Refrigeration I
Corequisite(s): ECTC 207 - Commercial HVAC Controls and Instrumentation
Refrigeration II is an advanced refrigeration course, requiring a basic knowledge of refrigeration systems and components. The student is introduced to operation, maintenance and design procedures for large commercial and industrial refrigeration equipment and associated instrumentation and control systems. Classroom training is enhanced by means of field trips to commercial buildings, when possible, for the purpose of viewing actual equipment at work and receiving additional on-site training through the sponsorship of plant engineering personnel. The course gives emphasis to understanding the operation of commercial equipment in the context of its performance under varying heating/cooling loads. Modulation is explained as a means to achieve higher efficiencies. The concept of the economizer cycle is introduced as an energy conservation technique.
