## COURSE OBJECTIVES

This course is an introduction to the design of thermal systems for indoor climate control. The concepts, design, application, and control of HVAC and Refrigeration are introduced through the use of fundamentals of thermo-fluids. The course is designed to provide a balance among theory and practical design principles and to introduce the students with real-world problems of HVAC design and applications.
