This design-focused course will help you determine if chilled water is the right choice for your application, then walk you through each step of the design process. You'll improve your ability to select chiller types and refrigerants, choose piping and pumping configurations, solve cooling tower design issues, size your equipment, analyze costs, and more. Daily problem-solving workshops will help you practice what you learn.
