Rethermalization ovens or “Retherms” are heated cabinets used to reheat previously prepared, stored and chilled food product to serving temperature all while retaining the food product’s color, flavor, texture and nutrients. Retherms are popular among schools, hospitals, prisons, and other...

The goal of this project is to determine and validate energy savings for a typical retrofit for two delta T valves in an HVAC chiller system. Delta T is the difference between the water supply and return temperature across a cooling coil. When downstream cooling coils have a low delta T, it can...

This project is investigating an energy management circuit breaker (EMCB) with several additional features. The EMCB is a single-or-double pole, thermal-magnetic circuit breaker commonly installed in low-voltage panelboards to protect an electrical circuit from damage caused by overcurrent,...

Lab or field test of phase change material (PCM) installed in air conditioning systems' supply air duct. PCM freezes during off-peak periods, then melts to offset compressorized cooling during peak hours. $47,000 included labor and materials to install Stasis on a customer site, on a 5 ton AC...

This project will evaluate performance of a water treatment system. This technology can be used in all ice rink facilities to replace conventional systems. This system can potentially offer significant energy savings and reduced maintenance costs by creating ice with fewer microscopic air bubbles....

This project will perform a series of field tests for a major fast food chain's current universal holding cabinets (UHC) and a new high-density universal holding cabinet (UHC-HD). The current UHC is configured to have 4 columns and 3 rows with the ability to cook and hold 12 menu items. The new...

This is a study of the market barriers that prevent emerging technologies from being adopted by the HVAC market. Its benefit is definition of possible solutions to increase adoption of EE...

In order to quantify the impacts of electric forklifts in outdoor applications and dispel the perception / misconception that electrics cannot perform in outside settings and adverse weather, EPRI intends to conduct electric outdoor forklift demonstrations at various locations. New learnings will...

Provide a demonstration project for commercial customers in SCE territory. This demonstration would replace ISP air conditioning systems with Variable Refrigerant Flow (VRF), Dedicated Outside Air Systems (DOAS), and Energy Recovery Ventilation...

Variable Refrigerant Flow (VRF) systems are fundamentally different from unitary or other types of traditional HVAC systems. The space is cooled or heated directly by circulating refrigerant to evaporators located near or within the conditioned space. The system will replace electric resistance...
