Abstract：
This paper presents the current situation of local outdoor meteorological parameters and the determination method of outdoor meteorological parameters for design. By analysing and comparing the advantages and disadvantages of heating cable floor radiant heating and low-temperature hot water floor radiant heating, it is determined that the first heating form is adopted in the Winter Olympic Village in Zhangjiakou competition area. The calculation of heating load, the determination of the length and spacing of heating cable, the arrangement of heating cable, the design of temperature control system and the design of toilet heating system are presented in detail, and the problems needing attention in design are pointed out.
