Abstract

This paper aims to verify the effectiveness of decoupling control of RCP with DCS while controlling condensed water of chilled water coil, and to improve the performance of the RCP system, which verified the applicability of the combined system with DCS through test bed experiments. The indoor temperature and relative humidity were satisfied while suppressing the generation of condensed water in RCP with DCS through the decoupling control. The moisture removal capacity was consistently 5 g/kg(DA), and the DCOP was between 0.2 and 0.4. Since the supply chilled water temperatures of CC1, 2 and RCP are mostly above 14°C, this will be higher than the chilled water temperature of the general air handling units, which will increase the utilization of natural heat sources in the future.
