Topic
|
General Description of Subject Matter
|
|
Duct Design
|
List the three overall goals in duct design, list the different duct design methods, and discuss how to determine the duct system design static pressure. Explain the difference between design friction loss rate and the actual static pressure loss through a duct. Explain how a ducts equivalent length is determined; use a duct calculator to look up the duct size, air velocity, and friction rate. List the criteria for selecting grilles and registers.
|
|
Testing and balancing air systems

|
List safety precautions to follow when working on gas furnaces. List general sequence of operations of an induced draft furnace. Interpret an led fault code on a furnace board.
|
|
Indoor Air quality
|
Define the meaning of indoor air quality. State the HVACR technician role as it relates to indoor air quality. Identify various pollutants and pollutant pathways that affect indoor air quality
|
|

ATTENDANCE POLICY
Regular and punctual attendance is expected of all students in all classes for which they have registered. Students absent or tardy (excused or unexcused) 15% or more may receive an “F” for the course or may be dropped from the course. A student that is compelled to be absent when a test is given, will petition the instructor, in advance, for permission to take the exam early. Prior to the last day of class, a student will be allowed to drop one exam from the required exams given during the course. Required work not completed by due dates will not be allowed to be turned in late without instructor approval. Students may be dropped from a class by the Registrar upon recommendation of the instructor who feels the student has been unjustifiably absent or tardy a sufficient number of times to preclude meeting the course's objectives. Persistent, unjustified absences from classes or laboratories may be considered sufficient cause for College officials to drop a student from the rolls of the College. Always communicate with your instructor.
If you must miss class: You are required to let your instructor know ahead of time. If that is not possible, you must communicate with your instructor as soon as possible. Come prepared for the next class. An absence is not an excuse not to the do the work, readings, etc.
A student will be allowed to drop one exam grade from the required exams given during the course with the exception of the Final Exam. The Final Exam may not be dropped under any circumstances. Requests to drop a grade must be submitted to the instructor, in writing, prior to the last day of the semester.
Required work not completed by due dates will not be allowed to be turned in late without instructor approval.
LAST DAY TO WITHDRAW
For the fall 2019 semester the last day to withdraw from a course with a “W” is November 25, 2019
Students are expected to follow all rules and regulations found in the student handbook and published online.
Scholastic dishonesty shall include, but is not limited to cheating, plagiarism, academic falsification, intellectual property dishonesty, academic dishonesty facilitation and collusion. Faculty members may document and bring charges against a student who is engaged in or is suspected to be engaged in academic dishonesty. See Student Handbook, “Student Rights & Responsibilities: Student Conduct ([FLB(LOCAL)]”.
Consequences for academic dishonesty may include:
- A grade of zero on any assignment that the instructor believes was completed dishonestly.
- A report of the academic dishonesty to the appropriate authorities at NCTC which may result in removal from the course and/or removal form the college.
DISABILITY SERVICES (Office for Students with Disabilities)
The Office for Students with Disabilities (OSD) provides support services for students with disabilities, students enrolled in technical areas of study, and students who are classified as special populations (i.e. single parents).
Support services for students with disabilities might include appropriate and reasonable accommodations, or they may be in the form of personal counseling, academic counseling, career counseling, etc. Furthermore, OSD Counselors work with students to encourage self-advocacy and promote empowerment. The Counselors also provides resource information, disability-related information, and adaptive technology for students who qualify.
If you feel you have needs for services that the institution provides, please reach out to either Wayne Smith (940) 498-6207 or Yvonne Sandman (940) 668-4321. Alternative students may stop by Room 170 in Corinth or Room 110 in Gainesville.
