Low-Cost Polymers Performing Organization: National Renewable Energy Laboratory Key Technical Contact: Jay Burch, 303-384-7508, jay_burch@nrel.gov DOE HQ Technology Manager: Glenn Strahs, 202-586-2305, Glenn.Strahs@hq.doe.gov FY 2004 Budget: $1,107K _____________________________________________________________________________________ Objective • Reduce the levelized cost of saved energy (COSE) for solar domestic hot water (SDHW) systems by ≥50%, from current COSE of 10–20 ¢/kWh to ≤5–10 ¢/kWh. Accomplishments • Two teams started field trials of their low-cost integral collector-storage (ICS) systems, with greater-than-expected savings for the Davis Energy Group/SunEarth (DEG/SE) ICS and lower- than-expected performance from the FAFCO ICS. • DEG/SE has finalized product design and manufacturing equipment design. FAFCO has initiated a major redesign of its low-cost SDHW, focusing instead on a thermosiphon system based on use of pool collector technology. • A new test protocol for ICS systems has been developed, and validation of the new method is ongoing, comparing long-term performance with the calibrated model. • A report on cost-reduction potential for cold-climate SDHW systems was published. Future Directions • Field trials will continue on the DEG/SE ICS, and field trials will begin with the redesigned FAFCO mild-climate thermosiphon SDHW. • DEG/SE will refine accessory components and plan for commercialization. FAFCO will continue refining the new thermosiphon design. • Pipe freeze tolerance and prevention using polymer piping systems will be established for at least two available PEX piping systems. • An RFP for development of cold-climate SDHW components, including tank and heat exchanger combination, will be issued. _____________________________________________________________________________________ 1. Introduction As described in the DOE Solar Program Multiyear T echnical Plan, Solar Heating and Lighting set the goal in FY 1998 to reduce the life-cycle cost of saved energy for solar domestic hot water (SDHW) systems by ≥50%. In FY 1999, focus was placed on reaching this objective for passive systems in mild climates. Assuming high volumes COSE for current mild-climate technology is ~10.2 ¢/kWh, giving a goal of ~5.1 ¢/kWh for the new technology. Two industry teams (DEG/SE and FAFCO) have been developing unpressurized polymer ICS systemswithload-sideheatexchangersandbegan field-testing them in FY 2004. DEG/SE’s ICS has a rotomolded tank and thermoformed glazing. Based on manufacturing issues, costs, and poor performance, the FAFCO team changed direction in late FY 2004 from an unpressurized ICS to a direct thermosiphon design based on the use of pool collectors. Both teams intend to commercialize products in FY 2005.PDF Image | FY 2004 ANNUAL REPORT DOE Solar
