Showcase your high-efficiency, low global warming potential (GWP) refrigeration system through a case study
The Refrigeration Team is conducting field studies of commercial refrigeration systems that use alternative refrigerant technologies (such as CO2 cascade, transcritical CO2, and ammonia refrigeration) and charge-reduction strategies (such as distributed systems). Case studies will cover a variety of technologies and applications and provide information on alternative refrigerants’ costs, benefits, system performance, and challenges to implementation.
If you are an interested member or a retail operator, contact us to participate.
By participating in a field study, operators will have the opportunity to showcase their efforts in developing and implementing refrigeration systems that balance energy performance with GWP reduction. Partnering with DOE also involves a high-visibility, objective third-party analysis of system performance.
The Team will collect data from participants on system performance, features, and cost over a monitoring period. Specific data points include:
- System Characteristics: Top-level layout and configuration of the system, schematics, and equipment used.
- Building Characteristics: Information regarding other building systems in place at the study site, including envelope, HVAC, lighting, etc.
- System Performance Data: Submetering or other monitoring of energy consumption of the refrigeration system (racks, condensers, and display cases). Ideally, data should span a time period that show the full range of operating conditions (summer/winter, high/low traffic periods, etc.). If submetered data are not available, participants can provide whole-building utility data.
- System Cost Data: To the extent possible, this includes installed costs or payback period.
- Baseline Information: If available, corresponding information on a similarly-configured “baseline” store utilizing a traditional refrigeration system.
- Other: Information on operation and maintenance procedures/costs, down-time figures, and other attributes.
How the Refrigeration Team Will Use Data
The Team will create a publicly-available case study document outlining the technologies studied and field results observed. All documents will be developed in collaboration with participants to ensure data confidentiality and agreeable presentation.
