ACR 1104 | Refrigeration Systems and Components
4 Cr. (3 lec., 3 lab)
Prerequisite: None. Offered in the spring semester. A comprehensive study of mechanical refrigeration systems emphasizing proper service techniques through analysis of the problem. Testing procedures, parts removal, and installation are covered in depth. A study of the computation of temperature-pressure relationship and related problems is included. Practical application is provided in the laboratory. Safety is emphasized.

ACR 1303 | Schematics
3 Cr. (3 lec.)
Prerequisite: None. Offered in the spring semester. The student will learn to read, draw, and interpret wiring diagrams and place the circuitry in operative arrangements with electrical and electronic symbols. System diagrams will be developed by the student for a wide variety of heating and cooling loads. Also included is a study of the distribution mediums such as duct design and sizing.

ACR 1404 | Introduction to Air Conditioning and Refrigeration
4 Cr. (3 lec., 3 lab)
Prerequisite: None. Offered in the fall and spring semesters. This course is designed to teach the principles of the basic refrigeration cycle, including temperature-pressure relationships, evaporation, condensation, heat transfer, and refrigerants. The identification and use of hand tools, as well as safety principles and practices will be taught. Practical application is provided through laboratory activities.

ACR 1603 | Piping and Load Calculation
3 Cr. (3 lec., 3 lab)
Prerequisite: None. Offered in the spring semester. This course covers the process of identifying tubing and pipe with practical applications in sizing and fitting to different configurations using mechanical fittings, soft soldering, silver brazing and aluminum soldering. Also included are the study of air properties and the instrumentation to meet the environmental needs of structures, residential and commercial, and the factors involved in the calculation of heating and cooling loads.

ACR 1704 | Commercial Refrigeration
4 Cr. (3 lec., 3 lab)
Prerequisite: ACR 1404 Introduction to Air Conditioning or consent of the instructor. Offered in the fall semester. This course is designed to teach the components, operation, and design characteristics of commercial refrigeration to include, but not limited to, walk-in cooling and freezing cabinets, ice machines, and water towers. Applications of these principles combined with practical experience on actual equipment will provide the student with the knowledge and skills to diagnose and repair equipment malfunctions.

ACR 1903 | Heating Technology
3 Cr. (3 lec.)
Prerequisite: None. Offered in the fall semester. This course covers the design, construction, operation, and servicing of fossil fuel heating equipment, and heat pumps both air to air and geothermal. The thermodynamics of heat flow through conduction, convection, and radiation are taught as an introductory part of this course. Humidification, dehumidification, and filtering are included.
