Theory and practical application cover the importance of AC/R systems for comfort and process, types of systems, how systems work, identification of AC/R system components, the properties of air and water vapor, and the use of psychometric charts for ACR process analysis. Emphasis on ASHRAE ventilation standards, IAQ basics, and introductory control point strategies. 3 Credits (2 Lecture - 3 Lab)

Air Conditioning Systems I

ACR236

Introduction to the air conditioning aspect of the heating, ventilation, air conditioning, and refrigeration (HVACR) industry. Designed to provide entry-level knowledge and skills needed to perform installation, troubleshooting, and service on residential and light commercial air conditioning systems, including split-system air conditioning units, package air conditioning units, and water-cooled air conditioning systems. 3 Credits (2 Lecture - 3 Lab) Prerequisite(s): ACR111. Corequisite(s): ACR238.

Air Conditioning Systems I (Load Calculation and Design)

ACR238

Introduction to the theory of heat gain, including the parameters used in determining a cooling load needed to provide total comfort. Topics include environmental conditions, load factors, construction materials, solar effects, and psychrometric characteristics. Skills developed include the ability to produce accurate cooling load calculations and properly size cooling equipment. 2 Credits (1 Lecture - 3 Lab) Prerequisite(s): ACR111. Corequisite(s): ACR236.

CFC and Refrigeration Management

ACR240

Study of the environmental impact of refrigerants and the laws that regulate how they must be handled. Designed to provide the knowledge and sensitivity required to work responsibly in the field. Analysis of the laws on venting and handling of CFC, HCFC, and HFC refrigerants covered in the Clean Air Act - Section 608. Course work prepares students to acquire U.S. Environmental Protection Agency (EPA) certification for handling the refrigerants, through the Refrigeration Environmental Protection Association, Inc. 1 Credit (1 Lecture)

Advanced HVAC System Service

ACR249
