Tier I Applicant
Awarded FRIP Funding: $50,000

Project Summary:This project is for a new refrigeration system in a new building. The refrigeration system is an innovation CO2 transcritical design with parallel compression and gas ejector technology using 350 pounds of R-744. This refrigeration system consists of a two-stage booster system with the same refrigerant moving from the low temperature compressors to the medium temperature compressors. The medium temperature gas from the low temperature compressor discharge and medium temperature loads is lifted by the ejector to flash tank pressure. The parallel compression CO2 gas is compressed at a higher suction pressure than medium temperature suction. This design is expected to deliver year-round energy savings between 8-10% compared with a traditional CO2 transcritical design. The compressor rack is furnished with a VFD (Variable Frequency Drive); it supports an optimal capacity control and energy consumption.

Grantee: Costco Wholesale Corporation
Location: Murrieta, CA
Tier I Applicant
Awarded FRIP Funding: $50,000

Project Summary:This proposed project is for a new refrigeration system in a new building. The refrigeration system is a CO2 transcritical design using approximately 4,800 pounds of R744. The CO2 rack has a medium temperature and low temperature suction group service a 148,000 square foot facility. The system includes heat reclaim during cold weather to reduce the amount of energy needed to heat the supermarket and utilize the same heat reclaim coil to dehumidify the store during hot weather. The dehumidification process uses energy from the CO2 system to reheat the air, increasing the energy efficiency of the system.  Additionally, because the air is cooled via the air conditioning system, the energy efficiency of the building will improve due to reduced frost on the refrigeration equipment as well as the dehumidification through a higher efficiency system.
