ASHRAE x Hawaii Energy Technical Training Day 3: Unitary AC (In Person)

ASHRAE Hawai‘i Chapter and Hawai‘i Energy are thrilled to bring seasoned instructor and consultant David Wylie to Hawai‘i for a four-day series of FREE workshops on electrical, mechanical and energy topics. Please register quickly, in-person seats are very limited. Classes will be held at the Hawai‘i Energy Training Room (50 N. King St. Suite #500, Honolulu HI 96817). The training will be also offered remotely via Microsoft Teams. Coffee and lunch will be provided.

Participants will learn about the fundamentals of HVAC systems found in residential and small-to-medium commercial and industrial facilities. The focus is on package-unit, split and VRF system components, controls, and applications. This course begins with the science of human comfort and heat transfer as it affects HVAC sizing and efficiency. Next we look at several types of unitary HVAC equipment, how it works, and the advantages of different configurations. We will take a look at new advances in HVAC technology for condensers, evaporators, and compressors including variable refrigerant flow.

After that, we explore control opportunities, equipment performance, and high tech systems. We conclude by investigating the impact of maintenance efficiency, fault detection, field auditing, and unit replacement economics.

This course presents the fundamentals of air-conditioning systems found in residential and small-to-medium commercial and industrial facilities. Some previous AC system experience is helpful, but this workshop covers the basics.

About the Instructors: David Wylie, PE, MBA

David Wylie (the “W” of ASW Engineering) has a wide range of energy engineering experience, including research, development, program design, measurement, feasibility study of electrical and mechanical systems, and energy supply for commercial and industrial facilities. He has a college teaching credential, teaches what he knows from experience, and has developed more than 20 courses that address energy-efficient systems. David takes sophisticated engineering concepts and relates them in a way you can understand in a friendly and practical way.
Several of David’s articles have been published in trade magazines, and he has written a book titled “New Refrigerants for Air Conditioning and Refrigeration Systems.” ASW Engineering has received awards for innovations in engineering from the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), Southern California Edison, and California’s governor.

Les Taniyama, PE

Leslie (Les) Taniyama heads up PSIG-HI (Power and Systems Inspection Group), a consultation and engineering firm which provides various technical services in Hawaii and other western United States. As an associate of PSIG-CA (California) DH Parr & Associates (Washington), Les’ disciplines include mechanical, electrical and energy engineering with work concentrations in HVAC design, facility consultation and forensic engineering.

After graduating with a degree in electrical engineering from the University of Hawaii, Les spent time as a contractor, manufacturer representative of HVAC equipment and now, as a consultant for facility managers/owners and engineering design/consultant for design engineering firms.

Les provides for energy auditing, monitoring, data analysis, design and commissioning part, of what has been developed as, the “Performance Design” process. The performance design also provides for his post participation in the design that allows for fine tuning of the system and operator training.

We will send participants a map and instructions on how to get to the training room prior to the class. Registration will close when we reach room capacity. If you cannot attend after registering kindly email [email protected] and [email protected] so that we can offer the space to another person. Mahalo.
