Development and Testing of an Energy Efficient Ultra-low Charge Ammonia Refrigeration System in a Food Processing Plant
The project is demonstrating an energy efficient chiller system using a low global warming potential refrigerant at a food processing facility.
Project is complete and the low-charge, packaged ammonia chiller installation is operating normally as confirmed by monitoring and verification (M&V) data. Results show that the ammonia chiller is 38 % more efficient than the R-507A chiller. The project team is now receiving monthly water treatment reports to track the change in the cycles of concentration for the R507A cooling tower. This allows monitoring of the amount of water consumed each month (gallons/month) and the number of gallons used per kWh of cooling provided.
This project is pilot testing and demonstrating an air-cooled, low-charge ammonia refrigerant-based, integrated package closed cooling system for an industrial food processing application. The project is demonstrating the effectiveness of a water-saving innovation with the use of a micro-channel, air-cooled condenser. The project is demonstrating the expected energy savings of 20% compared to a chiller using hydrofluorocarbon (HFC) refrigerant for similar end use at the same site. This system eliminates the need for water for cooling. The entire system can be prepackaged, factory charged, and brought to site as an integrated package which simplifies field installation and makes it cost effective.
Expected energy savings of at least 20% compared to a chiller using hydrofluorocarbon (HFC) refrigerant for similar end use at the same site. This system eliminates the need for water for cooling, which further adds to on-site cost savings.
