Abstract
This study presented a simulation method of thermal environment and heating and cooling load in spaces conditioned by air-handling units together with hydronic floor panels. The presented method enables the detailed simulation of the dynamic response of floor for thermal injection by hot or chilled water and thermal environment in spaces where operative temperature is controlled by air-handling units and floor surface temperature is controlled by floor panels. The fundamental characteristics of several types of heating operation and the effects of factors such as set point floor temperature and warming-up hours were clarified through simulations.
