Detailed Description
This course is designed to prepare students to operate air-conditioning and refrigeration systems in buildings in a safe, energy efficient, economical and environmentally conscious manner.

Program Context

Building Environmental Systems Program Coordinator: Roberto Cordovado
This is a compulsory course in the Building Environmental Systems Operator - Class 2 certificate program.

Course Critical Performance and Learning Outcomes

 Upon successful completion, students will be able to demonstrate the 
ability to:
 1. Perform simple calculations involving temperature, heat and 
    changes of state and be able to define the terms involved.

 2. Describe, using relevant diagrams, the basic refrigeration cycle.

 3. Explain the purpose of compressors in refrigeration and describe
    the safe operation of the main different types of compressors.

 4. Explain the purpose of heat exchangers in condensers and
    evaporators and describe the efficient operation of the main
    types of heat exchanger.

 5. Describe the purpose of metering devices in refrigeration and
    identify the advantages and disadvantages of the different types
    in common use.

 6. Interpret electrical control diagrams associated with air
    conditioning and refrigeration and describe the functioning and
    trouble-shooting of the main electrical components involved.

 7. Use a psychrometric chart to perform simple calculations
    involving air conditions.

 8. Prepare an effective preventive maintenance schedule along with
    relevant reading and trouble-shooting charts.

 9. State and explain regulations and procedures involving the safe
    and environmentally friendly use of refrigerants and
    refrigeration equipment.

10. Describe how the vapour compression cycle can be reversed to 
    deliver heating as well as cooling to a building.

11. Explain the principles of operation of the various types of

12. Describe alternative refrigeration systems. 

Evaluation Plan
Students demonstrate their learning in the following ways:

Project Outline          5%
Final Project           25%
Mid-Term Test           30%
Final Exam              40% 

Full participation and attendance is recommended for this course.  
Students who miss a class are responsible for any information 
discussed, assigned or distributed in that class period.

Since this is a professional credit course, marking standards
reinforce professional practice by demanding legible, tidy work. 
Written assignments should be well organized and grammatically
correct, with proper spelling and punctuation.  Late assignments are
subject to penalty.  

To obtain a passing grade, students must complete and obtain a 
passing grade on all combined assignments and tests (term work) and 
also a passing grade on the final exam.

Students may withdraw up to the 3/4 point of the course duration 
without academic penalty.  For example, if your course is 14 
sessions, you may withdraw (in writing) up to the 11th session 
without academic penalty. If you withdraw after this point, you will 
receive the grade earned. This policy applies only to courses and 
not seminars or workshops.
Provincial Context
The course meets the following Ministry of Training, Colleges and Universities requirements:
