Expert ID: 722680 Michigan, USA
The effective design and development of a refrigerant compressor includes knowledge of many functional areas of engineering expertise. Among these are machine design, stress analysis, bearing design (rolling element and hydrodynamic), lubrication, tribology, materials analysis and selection, induction motor design and motor protection, fluid flow, heat transfer, thermodynamics, noise and vibration, performance testing, reliability testing, packaging and shipping, air-conditioning applications, heat pump application, and refrigeration application.
In addition to his compressor and related HVAC experience, Expert was vice president of engineering for a company that manufactured heat exchangers for domestic and commercial refrigeration products. He has knowledge of the design and manufacture of refrigerant heat exchangers, domestic refrigeration appliances (white goods), and commercial refrigeration equipment.
Expert has extensive experience developing new mechanical and heat transfer technology with 17 years in progressive engineering management positions, including vice president of engineering. He also has five years experience managing numerous consulting projects. Expert is a strategic thinker with vision and innovative solutions to complex technical and managerial problems. He has strong expertise and a proven track record at
developing new technology, new methods and new systems in complex engineering environments. He is an inventor on over 29 patents.
He developed a new web-based system to find and display engineering drawings to any authorized person in the company, greatly improving communication and reducing errors. He developed a new web based engineering change management system improving communication, eliminating errors and reducing average
approval time from 31 to 11 days. This system was adopted for electronic document approval throughout the company.
Expert developed a new web-based product cost estimate system reducing average completion time from 40 days to 15 days. He implemented a new project management system incorporating stage/gate processes to better communicate, manage and ensure strategy alignment of all engineering projects. All projects completed under budget and on schedule. He selected and implemented computer aided engineering tools including Computer Aided Design (CAD), Product Data Management (PDM), and Finite Element Analysis (FEA). Implementation of these tools improved team communication, product quality and reduced product development time.
Expert has over 30 years’ experience in product development, including 17 years in progressive engineering management positions culminating with seven years as vice president of engineering. During this time, he focused heavily on improving the efficiency and effectiveness of the engineering process by eliminating errors and reducing time to market. This was accomplished by developing and implementing state of the art tools aimed at creating a process oriented, procedure driven engineering culture. These procedures and processes included a well-defined stage gate project management process based on design and manufacturing reviews, integrated project teams, concurrent engineering and six-sigma product design.
As part of the executive management team, Expert also implemented the tools and procedures to develop product and technology strategy in support of the business strategy. This included portfolio planning and project matrix analysis. Taken all together, these tools and processes constitute Integrated Product Development whereby he was able to improve the entire product realization process by minimizing non-value added effort while reducing time to market and improving customer satisfaction.
A client developing a new vending machine was having "freeze up" problems with a rotating shaft. Two days of his on-site consultation resulted in a determination of the cause of the problem, a redesign of the shaft seals, and a happy client.Designed 75-200 T liquid and air cooled chiller line using screw compressors and brazed plate heat exchangers. Designed 50 T water cooled chiller for domestic water heating application.Analyzed, designed and tested air source swimming pool heat pumps to meet increased minimum efficiency standards in Florida.Designed forced air refrigerated food service table to meet new NSF temperature requirements.
