【 摘 要 】

In a conventional swimming pool temperature control, the return water temperature is considered as the representative temperature of the swimming tool rather than the average temperature although the latter is more representative regarding to thermal comfort. This is because the average temperature is difficult to measure. This paper uses field data to identify a relationship between the average and the return water temperature and develops a temperature control method based on this relationship. This control method is applied to an open-air swimming pool, for which the heat is supplied from a PCM storage tank. Numerical study, which is resorted to a simulation platform constructed using TRNSYS and MATLAB, is used to analyze the control performance of the new method and demonstrate its effectiveness by comparing with the conventional control.
