The accelerated demand for refrigeration and air-conditioning applications has increased the need for a greater number of practical, technical and sales personnel who have a thorough understanding of the various refrigeration systems and controls.
Refrigeration Systems and Controls has been prepared to provide the student with a thorough understanding of theory and operation of various types of control devices and systems. Troubleshooting skills will also be developed through a number of controlled faults incorporated into the system.
This manual is organized in a unit/exercise format with clearly-stated behavioral objectives for each unit and each exercise contained within a unit. Each unit includes a Unit Objective, background Discussion material, New-Word identification and definition and a listing of the materials necessary to conduct the various exercises contained in the unit. Each exercise within a unit includes an Exercise Objective, Discussion material, step-by-step Procedure, Conclusion and essay-type Review Questions. Units are concluded with an objective-type Unit Test. The training manual also contains various supporting appendices such as Mechanical and Electrical Service Analysis, Troubleshooting Flowcharts, Pressure/ Temperature (P/T) Chart of Refrigerants, Conversion Factors, Glossary of Terms and Bibliography.
The material presented in this manual is intended to create a practical sense of good judgment and a level of refrigeration and air-conditioning knowledge that will enable you to enter the more specialized areas of study in the field of refrigeration and air-conditioning.
The answers to all procedural questions, review questions, and unit test questions are provided in the Lab-Volt Instructor Guide Refrigeration Systems and Controls.
