长江流域住宅分散式供暖改造案例及分析
Decentralized heating for residential buildings in Yangtze River basin: A reforming case and analysis
摘要：
针对目前长江流域住宅冬季室内温度低、舒适性差的问题，在合肥某住宅安装了空气源热泵和辐射地板供暖系统。测试结果表明，辐射地板采用35 ℃的热水供暖时，室内温度16~18 ℃，竖直方向温度分布均匀，能较好地满足人员舒适性要求。结合该供暖改造案例，在室内热舒适和供热量等方面分析比较了辐射地板和送风末端，并探讨了空气源热泵作为长江流域住宅分散式供暖热源的适宜性。
Abstract：
In view of the low indoor temperature and unsatisfactory thermal comfort in the residential buildings in Yangtze River basin, a heating system composed of air-source heat pump and radiant floor is installed in an existing residence in Hefei. The test results show that when hot water with temperature of 35℃ is adopted, the radiant floor heating could provide a comfortable thermal environment with indoor air temperature of 16 to 18℃ and uniform in the vertical direction. On the basis of this case, compares the air-supply terminal and radiant floor in indoor thermal comfort and heating capacity, and analyses the feasibility of air-source heat pump as heat source of decentralized heating for residential buildings in Yangtze River basin.
