Characteristics of Heat and Humidity Transfer Between Aquatic Holding Tanks and Indoor Air

This study established a comprehensive system to investigate heat and humidity transfer involving aquatic holding tanks' walls and exposed water surfaces and the indoor environment. We manipulated tank water temperature and circulating pool water volume. Measurements included air temperature and humidity within the experimental chamber, tank wall temperatures, condensation levels, and various parameters related to heat exchangers and circulating water in both tubular and shell processes. The analysis characterized heat and moisture transfer coefficients on horizontal and vertical tank surfaces across different water temperatures. Notably, we identified correlations for these coefficients in the literature and established a linear relationship between water vapor diffusion and aquaculture pool water volume. These findings have practical implications for calculating air-conditioning loads in aquatic market buildings and heating/cooling needs in holding tanks.
