CHILLER AND HVAC-CURRENT AND COMMON ENGINEERING PROBLEMS & THEIR SOLUTIONS IN INDUSTRY

INTRODUCTION FOR CHILLER AND HVAC-CURRENT AND COMMON ENGINEERING PROBLEMS & THEIR SOLUTIONS IN INDUSTRY

This course is industry designed, to provide a broad understanding of the improvement methodology, concepts, and process. The methodology is presented with case studies and examples drawn from service, business process and manufacturing applications. The integration of manufacturing and maintenance is also addressed. With a heavy practice orientation, as much as a third of your time will be spent working through interactive practical exercises and assessments. This course is designed as an introduction to concepts and methodology. chiller and hvac-current and common engineering problems & their solutions in industry

COURSE OBJECTIVE

This training program is designed to provide an understanding of engineering related problems related to industry globally and a clear sense of what is required to effectively structure, establish measurements and solve problems. Participants will learn the goals and deliverables behind the solutions. Methodology as well as the most commonly used tools within each phase will be discussed. Participants will also learn how to support a problem solving initiative within their organization.

• Understand the benefits and implications of a HVAC / Chiller engineering problem solving program, and relate the concepts to the overall business mission and objectives.
• Think about his/her organization as a collection of processes, with inputs that determine the output.
• Use the concept of HVAC and Chiller engineering problem solving to evaluate the capability of a process or organization.
• Recognize the engineering problem solving model used to improve processes.
• Recognize the organizational factors that are necessary groundwork for a successful engineering problem solving program.
• Integrate the HVAC engineering problem solving program effort with other process improvement initiatives.
