Oak Ridge National Lab (ORNL), with its partner 3M, is developing adhesive chemistries for bonding aluminum and copper during heat exchanger manufacture, resulting in enhanced bonding and significant energy savings.

The goal is to develop a standard protocol to verify site-based savings for advanced rooftop unit (RTU) control (ARC) retrofits, based on manufacturer variable frequency drive (VFD) data. This will streamline the acquisition of 1 aMW of ARC retrofits and lower the cost of the impact evaluation. This project will draft a standard protocol to verify ARC retrofit site-based savings using Catalyst controller data. The project will compare best practice (unit-level, true-power over one-year with daily baseline cycling, as reported in Pacific Northwest National Laboratory (PNNL) study) and four simplified savings methods, to determine a simplest-reliable method. Deliverables include a draft protocol and presentations to the RTUG and, if appropriate, to the RTF. Once approved, the standard protocol would allow the streamlined acquisition of ARC retrofits because baseline metering and long-term baseline cycling would not be required. Once 1 aMW of ARC retrofits (approximately 1,000 RTUs) are reported, several years of Catalyst controller data would be available for most of the units for the impact evaluation. Using the standard protocol and manufacturer data, no post-post cycling or additional instrumentation, such as Wattnodes for unit-level true-power, will be required.

Optimized Thermal Systems, with their partners Heat Transfer Technologies, LLC, and interest from United Technologies Research Center, will develop a manufacturing procedure for a serpentine heat exchanger for heating, ventilation, and air-conditioning systems that has 90% fewer joints than current heat exchangers.

High performance, low-load homes face unique space conditioning challenges that are not adequately addressed by HVAC design practices and equipment offerings. Equipment manufacturers have yet to include a diverse set of low-capacity equipment in their product offerings due to a lack of understanding of (1) where the low-load home market is headed and (2) the load profiles typical to low-load homes. This project looks to address both of these information gaps and ultimately send the necessary low-capacity equipment market signals to manufacturers, enabling them to design better products to meet production builder needs. The team will develop a technical whitepaper and presentation on the performance and cost tradeoffs of various equipment types/systems at meeting the comfort requirements of low-load homes, and forecasting the market penetration and equipment needs for these low-load homes.

This project will develop and demonstrate a Climate Appropriate Air Conditioning system for commercial buildings. The heart of this system is an intelligent HVAC controller that processes signals from building sensors and system feed-back to maximize system efficiency. This control system will manage two technologies to optimize building energy and peak demand reduction. Getting fresh air into commercial buildings is a code requirement. However, the ingress of hot air into a cooling system and vice versa presents an inefficiency problem. This project will evaluate heat-recovery ventilation (HRV) and indirect evaporative cooling (IEC) to decrease the temperature of the incoming air in the summer and increase it in the winter. Both technologies can be intelligently controlled by the building controller to reduce cooling and heating costs. This project will also research low global warming refrigerants for commercial buildings
