Research and analysis of moisture load calculation method about recreational indoor natatoriums

The main factor of indoor natatorium air environment effective control depends on the accurate prediction and calculation of moisture load. At present there are various calculation methods about indoor natatorium moisture load at home and abroad, and the calculation results vary widely. Through comparing the calculation method, calculation formula and parameter selection, analyses the advantages and disadvantages of different calculation methods and the existing problems. Divides the indoor moisture sources into the pool, pool wetland and person, three main moisture sources. Applies the heat exchange and mass transfer analogy principle, establishes the corresponding physical models to the moisture sources, puts forward the moisture load calculation formula based on recreational indoor natatoriums, and verifies the accuracy of the model calculation.
