概要を開く

In this study, basic experiments and predictive calculations using a terracotta wine-cooling pot were performed to develop a cladding for evaporative cooling by internal water and to build a calculation model for predicting the performance. A terracotta panel with hollows for external wall cladding is already found in the market and possible development can be expected after some modification. Experiments on pots that accumulate water showed that the surface temperature was lower than ambient temperature by about 5 °C in a room with ambient temperature 20 °C and absolute humidity of 0.0044kg/kg'. The wetted area ratio of the outer surface of the pot filled with water was estimated to be 0.55 when the surface convective transfer coefficient of vertical wind velocity was 0.3 m/s. The results from the calculation model for predicting the evaporative cooling effect of the pot were consistent with the experimental results.
