Abstract
We proposed a simulation model for the floor heating-cooling system combined with air source heat pump and carried out some calculations to clarify the effects of various factors on thermal environment and energy consumption. As a result of simulations, we note that the ratio of PMV (Predicted Mean Vote) from -0.5 to + 0.5 is mainly effected by operating time and temperature of slab surface. As for full day operation, it is effective that the slab is thin and the water pipe is buried shallowly in the slab, and it is proper in Fukuoka to control the slab surface temperature at 32°C in winter and 24°C in summer.
