中文摘要：

辐射供暖房间空调器（RHRAC）是在传统房间空调器的基础上增设地埋冷凝管,以制冷剂为热媒直接进行地板辐射供暖。针对夏热冬冷地区的住宅建筑,模拟计算了RHRAC供热工况的冷凝温度,利用压缩机的性能曲线计算了其供热能效比EER,将RHRAC系统与常用的采暖方案进行初投资、运行费用的比较分析。得出结论：RHRAC供热工况的冷凝温度仅35℃即可满足采暖需求,供热能效比达3.17,运行费用最低,是夏热冬冷地区住宅建筑采暖的一种良好选择。

英文摘要：

The Radiation Heating Room Air Conditioner（RHRAC） has embedded condenser pipes more than the traditional room air conditioner. Refrigerant is used as heat medium for direct floor radiant heating. For the residential construction in area with hot summer and cold winter, the condensing temperature and energy efficiency ratio of RHRAC under heating condition are calculated by simulation and the compressor performance curve. Comparative analysis is made about the initial investment and heating operating cost of the RHRAC and some other heating ways which are commonly used. Conclusions are drawn： Under heating condition, the RHRAC has lower condensing temperature（35℃）,higher EER（3.17） and the lowest operating cost. It＇s a good choice to use RHRAC for residential construction heating in area with hot summer and cold winter.
