Résumé

The working conditions of the refrigeration unit for marine refrigerated containers or reefers change drastically during sea transportation. In order to achieve the precise control of carriage temperature for marine refrigerated container, the refrigeration unit should have the strong capability to well adjust its cooling capacity. However, the inner temperature of marine refrigerated container usually fluctuates obviously under chilled mode when traditional on/off control is adopted due to the low heat load. A novel capacity control strategy using variable-frequency compressor combined with hot-gas by-pass technology was developed to realize energy-saving operation and achieve high control accuracy of carriage temperature. The developed capacity control strategy was validated on a test rig for marine refrigerated container. The experimental results of performance tests showed that it can kept the carriage temperature stable and its accuracy is ±0.2°C.
