Purpose:
- Introduce the basic concepts of controls applied to HVAC system:
- Direct digital control system
- Control loop
- System modeling for control purpose
- Transferring function
- Selecting and locating sensors and actuators
- Design tuning control algorithms
- Design and program control sequences for HVAC systems
Objectives:
By the end of the term, the students of this class should:
1. Understand the basic concepts of control loop
2. Understand the basic structure of direct digital control system
3. Get familiar with the sensors, actuators, and control algorithmscommonly used in HVAC systems
4. Be able to design a simple control algorithm for a HVAC system control
5. Be able to select, locate, and size most commonly used sensors and actuators in HVAC systems
6. Be able to design and program control sequences for HVAC systems
Prerequisites:
1) AE 220 or
2) MEM 414 or
3) Approval by the instructor
Textbooks:

Important: Earning a final grade less than 50% will fail to pass this course.
Homework:
- Assignments, each consisting of a number of problems, will be given on the day of each class and due at the beginning of the next class on Tuesdays.
- Your solutions can be either typed or handwritten. But, losing credits due to the illegibility of your solutions is your sole responsibility.
- No assignments submitted via WebCT are accepted.
- Late due assignments are generally NOT accepted.
- A late due assignment may receive up to 70% of the actual credits earned on this assignment with areasonable excuse, which is subject to the instructor's judgment.
- Solutions will be posted on the course homepage (WebCT).
- No assignments are accepted, by any excuse, after the corresponding solutions are posted on WebCT.
- The office hours are your resource to accomplish these assignments and this course. Please stop by and bring in any of your questions in conjunction with your assignments and this course.
Handouts:
- The class notes and other pertinentmaterials will be posted on the course homepage (WebCT). The copyright of these materials shall be respected.
Exams:
- A final comprehensive exam, accounting for 30% of your final grade of this course, will be given in the final week. You have 100 minutes to finish this exam with open book and closed notes.
- Incomplete solutions, lack of work-out steps toward answers, and illegible handwriting will cause you to lose partial or full credits on your solutions.
- Exam problems are derived from your reading assignments, class notes and homework assignments. Study and review of these materials before the exam will help you to crash the exam.
- Please be advised that there will be NO time for you to dig in the book for solutions during the final exam, because the exam is well designed for a full working load of 100 minutes solely in solving problems. The open book is for you to refer to equations, charts and tables in the book in assistance to solving problems.
- No make-up exam will be granted unless:
- A student is deeply sick on the day of exam with a doctor's written proof; or
- A student runs into a family emergency, involving an immediate family member, on the day of exam with a proof letter from either a parent or guardian of such a student.
- A petition of a make-up exam must be sent to the instructor within three days following the exam day.
Class attendance:
Class attendance will be randomly checked. Each absence caught will cause losing 2 % of the points, up to the maximum of5 % points for class attendance.
WebCT:
The course syllabus, class notes, assignments and other reading materials will be posted on WebCT for you to access and obtain. All important class announcements will be published and communicated via WebCT. It is the sole responsibilities of the students to get used to using WebCT. For those of you, who are not familiar with the WebCT environment, please resort to any available resource to learn and cope with it.
For WebCT related questions, please check the student WebCT manual at

Email:
Students' email related to this course and sent to the instructor will be replied on every Tuesday and Thursday. Please check your Drexel email accounts on a regular basis for class updates.
For the benefits of students, the questions that demand a rather complex explanation shall be asked in person during the office hours.
