Alaska SeaLife Center: Located on the shores of Resurrection Bay in Seward, ASLC is Alaska’s only public aquarium and ocean wildlife rescue center. ASLC submitted this project to the Alaska Energy Authority for consideration under the Emerging Energy Technology Fund Round Two solicitation. ASLC is the primary stakeholder of this project. YourCleanEnergy LLC: YourCleanEnergy LCC (YCE) is a clean energy consultant based in Anchorage, Alaska. YCE recommended the CO2 refrigerant heat pumps as a solution to displace an expensive electric boiler and provide heat to existing medium temperature 160F to 180F) hydronic baseboards, unit heaters and air handlers in the facility. YCE, in association with EDC, Inc., designed the system and was instrumental in installing and commissioning it. Engineering Design and Consulting, Inc.: EDC, Inc. is a professional corporation based in Anchorage that has been registered in the State of Alaska in the fields of Electrical and Mechanical Engineering since 1994. The firm has been providing all aspects of engineering services for a wide variety of governmental, commercial and private concerns throughout the State of Alaska since that time. The firm is owned by four principals: John Faschan, P.E., Kevin L. Hansen, P.E., Ernie Hetrick, P.E., and John Pepe, P.E. Mayekawa USA: Mayekawa has been manufacturing large-sized air‐conditioning heat pumps since 1971. The CO2 refrigerant Unimo W/W uses water as its heat source (including waste hot water) to generate hot water and cold water simultaneously. This industrial heat pump achieves remarkable energy savings by combining simultaneous heating and cooling from one unit boasting a combined coefficient of performance (COP) of 8. This performance is achieved using the trans-critical cycle of its refrigerant CO2, providing hot water outlet temperatures of up to 194F. For example, a heat source water temperature of 71.6F results in a capacity of 26 ton (194F). This makes Unimo W/W ideal for applications that require both heating (high quality hot water) and cooling on a constant basis such as food processing facilities, resorts and hotels. Trane USA: Trane is a global provider of chillers, heat pumps and other HVAC systems, including its web based Tracer SC and Tracer ES building automation controls. Trane provided and installed the Tracer ES controls for the project. Alaska Energy Authority: The Alaska Energy Authority provided $537,560 in funding through Round 2 of the Emerging Energy Technology Grant Fund. Rasmuson Foundation: Rasmuson Foundation provided $50,000 in supplemental funding through a Tier 2 grant. Alaska Center for Energy and Power: The Alaska Center for Energy and Power (ACEP) an applied energy research program based at the University of Alaska Fairbanks, provided technical support in data collection and will provide an independent performance analysis to AEA.
