GENERAL DESCRIPTION OF SUBJECT MATTER FOR EACH LECTURE/DISCUSSION

Topic	General Description of Subject Matter
The Refrigeration Cycle	A thorough review of the refrigeration cycle. Discuss the function of each of the major components of the mechanical compression refrigeration cycle commonly in use in virtually all air conditioning and refrigeration equipment. Discuss the primary refrigerant lines. Discuss the state of the refrigerant in various locations throughout the refrigeration cycle. Discuss the heat exchanges taking place throughout the refrigeration cycle.
Refrigerants and Their Properties	A review of commonly used refrigerants.
Refrigerant Management and the EPA	Discuss the significance of the Montreal Protocol. Outline the major provisions of the title 5, section 608, of the 1990 clean air act. Determine the EPA specified recovery level for given refrigerant and system. Discuss the requirements for EPA certification. Explain the different types of refrigerant recovery. Discuss proper refrigerant recovery technique. Discuss the difference between recovered, recycled, and reclaimed refrigerant.
Fundamentals of Psychrometrics and Airflow	Discuss the factors affecting human comfort. List the ways the body dissipates heat. Explain the relationship between dry bulb, wet bulb, and dew point temperatures. Plot points on the psychrometric chart given any two variables. Locate all unknown air properties on a psychrometric chart from the intersection of two known air properties. Calculate the mixed air temperature of two different temperature airstreams. Calculate CFM from velocity and area. Explain the difference between FPM measurements and CFM measurements. Explain the differences between static pressure and velocity pressure.
Duct Design	List the three overall goals in duct design; list the different duct design methods. 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 duct’s 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.
Principles of Combustion and Safety	List the most common types of fuel gages and compare their properties. List the three essential components of complete combustion. Describe the two types of flame and list their characteristics. List the products of complete combustion. Explain how CO is produced and how to keep Co out of combustion gages. Explain the combustion air requirements for gas furnaces. Define AFUE. List the certifying agencies for gas fired equipment.
Green Buildings and Systems	Recognize the different materials used in basic construction and select the proper procedures and methods of construction for each. Describe the different insulation R values of common building materials. Relate the importance of fire dampers in construction; incorporate the different methods of construction necessary for a successful residential or commercial project. Forecast what part of a HVAC system needs to be installed during each phase of construction. Explain the importance of LEED certification.

 

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

 

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.

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:

• First offense – All participants involved will receive a grade of 0 on the assignment
• Second offense – The student(s) will be reported to the appropriate NCTC authorities who will then take action that may result in the student’s removal from the course and/or the college.

 

Student Success Center

The Student Success Center is designed to help all students at NCTC develop tools to achieve their academic goals. The center links students to FREE tutoring, including a Writing Center, a Math Lab, and free online tutoring in the evening.  The program helps students acclimate to college by providing students free interactive workshops. For more information, please visit your nearest Student Success Center.
