Project Introduction
NEC’s goods warehouse has introduced a fresh-air system. By optimising airflow and using a 3-coil heat-exchange mechanism, it replaces the traditional high-power air-conditioning system. This creates a cooler and more comfortable working environment while still meeting the customer’s temperature requirements for the warehouse.
At the same time, the fresh-air units offer strong humidity control. They effectively prevent condensation from forming on the walls of other floors, maintain stable humidity levels, and help avoid mould growth as well as damage to precision components.
In addition, because the warehouse temperature remains stable on average throughout the year, the system also reduces the operational management burden.
Key Results
The application of the fresh-air system has significantly improved the warehouse’s energy efficiency. Air-conditioning system power consumption dropped from the original 97.5 kW to approximately 7.5 kW, delivering substantial energy savings and lowering long-term operating costs.
Through precise airflow control, overall temperature distribution has become more uniform, avoiding localised overheating or uneven cooling.
Humidity management has also been highly effective: water seepage and condensation problems have been reduced, a dry storage environment is maintained, and the preservation quality of the goods has been enhanced.
