       Course Name: Introduction to Air Conditioning

       Credits: 4 (3 lecture; 3 lab)

II.    Prerequisite

None

III.   Course (Catalog) Description

Course present theories, demonstrations and lab experiences in area of basic vapor compression cycle in refrigeration. Content includes functioning and operating characteristics of mechanical re-frigeration system: condensers, evaporators, compressors, refrigerant control devices, refrigerants, test equipment, and special service procedures connected with basic refrigeration cycle. The Clean Air Act set by EPA for proper use of refrigerants explained. Fee $40.00

IV.   Learning Objectives

Develop skills to do the following:
1. Theory: 
   A.    Solving English and metric problems of length, area, volume, pressure, temperature.           
   B.    Explaining state of matter, pressure, force, temperature, heat, heat transfer, energy, energy transfer, evaporation, condensation, super heat and sub cooling.
   C.    Describing properties of various refrigeration.
   D.    Recognizing and explaining the function of major components of the refrigeration cycle.
   E.    Refrigerant management - Recovery/Recycling/Reclaiming

2. Diagnosing:
Learning proper use of basic and specialized tools to service and install air conditioning and refrigeration system.

3. Laboratory:       
Measuring parts; making single flare, and swaged tubing connections; identifying and selecting fittings; making a complete tubing and piping assembly; testing for leaks, installing testing and charging access valves; learning to read pressure temperature gauge. Soft soldering, silver brazing, pipe threading, etc. is included among laboratory projects.  Using refrigerant recovery equipment, deep vacuum pumps, etc. to explore the working refrigeration cycles operating parameters.

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:
