Cooling system; has carbon dioxide and ammonia refrigerant circuits coupled with combined vaporizer and condenser unit, formed with rectangular inner container inside cylindrical outer container

摘要

The system has a closed carbon dioxide refrigerant circuit with at least one compressor (2) and at least one vaporizer (1) and a closed ammonia refrigerant circuit with at least one compressor (3) and a condenser unit (4). The circuits are coupled by a combined vaporizer and condenser unit (5), which is formed with a rectangular inner container inside a cylindrical outer container.
