Air Conditioning and Refrigeration

What will I learn in this program?

Students successfully completing the ET 135A, B, C Series and the ET 139C courses will learn the fundamentals of calculating air conditioning loads with a brief introduction to the Trace 700 computer program which can calculate these loads. Properties of the air water vapor mixture which comprises the air around us are studied in detail to understand the energy changes in cooling, heating, humidifying or dehumidifying the air water vapor mixture. The quantity of air required to absorb a particular load can be calculated by the student from what is learned. The basics of sizing ductwork to distribute the required amount of conditioned air to the place where it is needed is also covered in the course. The fundamentals of mechanical refrigeration are also covered in the course which has application in cooling conditioned air for comfort purposes and for refrigeration for food preservation purposes. The basics of fluid mechanics are covered in detail in the ET 139C course. Persons without prior experience in this field will have substantial technical understanding to advance from trainee entry positions. Persons already in this field of can improve technical knowledge to assist in advancement to positions of more responsibility. On the whole the most value of the course has been to persons already in the field who wish to advance by increasing their technical background such as a beginning drafting person in an engineering firm advancing to become a designer.
