【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。更多还原

【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.更多还原
