首发时间:2018-10-24
摘要:对重庆地区空气源热泵常规地板辐射供暖系统和毛细管网辐射系统进行测试,分别在30℃,35℃,40℃三种不同供水温度,0.83m3/h,0.7m3/h,0.5m3/h三种不同流量下,从达到房间设定温度和辐射表面温度的响应时间等两个方面进行对比。结果表明:在重庆地区,相同实验条件下,从辐射表面温度角度分析,初始温度为14.8℃时,毛细管网系统的响应时间为3.2h,且系统稳定时,地面温度可达到27.6℃;而常规地暖系统未达到设定温度,仅能达到21.6℃;从室内空气温度角度分析,初始温度为11.9℃时,毛细管网系统的响应时间为3.2h,且系统稳定时空气温度可达到18.3℃;而常规地暖系统的响应时间为5.3h,而稳定时仅能达到16.6℃。

Radiant Heating Contrasting Experimental Research on System\'s Response time
Abstract:The air source heat pump conventional floor radiant heating system and capillary net radiation system test in Chongqing, respectively from 30 ℃, 35 ℃, 40 ℃ three different water supply temperature, and under 0.83 m3/h, 0.7 m3/h, 0.5 m3/h three different flow, to compare the time which the room temperature reach the setting temperature and the radiant surface temperature reaches steady state. The experimental data, which indicated that in Chongqing, under the same experimental condition, on the one hand, from the surface temperature perspective, capillary net radiation system\'s response time is 3.2h when the initial temperature is 14.8℃, and the surface temperature can reach 27.6℃ when the conventional heating system can just reach 21.6℃ that not reach the setting temperature. From the indoor air temperature perspective,capillary net radiation system\'s response time is 3.2h when the initial temperature is 11.9℃, and the indoor temperature can reach 18.3℃ when the conventional heating system can just reach16.6℃ and its response time is 5.3h.
