Mechanical Drawing & Engineering

This first part of this course introduces the Power Engineering student to basic drawing and drafting techniques. Technical sketching by freehand sketch or one carried out with the use of simple drawing instruments are involved. The student will set up sketches using center lines and recognize standard views of objects. The second part of the course deals with general layout of heating, ventilating, and air conditioning (HVAC) systems found in large facilities and industrial plants. The student will sketch and describe the operation of various air conditioning systems. Discussion on the design of combined air conditioning systems, alternative system arrangements, and the factors to be considered when selecting an air conditioning system are covered. The airflow behavior and movement of air through distribution systems by looking at designs and components of duct systems used in air conditioning. Finally, an introductory study of heat gains and losses in large buildings and industrial plants is done.
