Abstract

Ceiling Radiation Cooling Panel (CRCP) is an effective mean of reducing building energy consumption while improving indoor thermal comfort. Although this technology is currently widely used, there is a lack of relevant cases and studies in sub-tropical and tropical regions with high refrigeration demand. This paper proposes and verifies the applicability of a novel low-temperature chilled water driven CRCP in Hong Kong through experiments. The energy-saving potential is analysed, and the results show that the novel CRCP system can achieve a maximum reduction of energy consumption by 55.9% compared to the traditional Variable Air Volume (VAV) system, particularly in the summer days with high cooling demand.
