摘要
研究沈阳市典型房间采用太阳能与外网联合的地板辐射供暖系统的经济性，包括系统初投资、费用年值等，为太阳能采暖系统的研究与推广提供参考。以沈阳市某71.52 m2的典型房间为例，利用自行开发的太阳能与外网联合供暖计算软件，对比典型配套太阳能供暖系统的初投资值、费用年值及回收年限值等，并作出简要分析。利用软件计算得出典型配套系统的初投资、费用年值等经济性参数对比表，针对沈阳市70 m2左右的采暖房间而言，若采用太阳能与外网联合的地板辐射供暖系统，初投资值大约在3万～5万元不等，回收年限均在10年以上。对于沈阳市普通热用户，从人居收入方面考虑，选择初投资值较低的太阳能与外网联合供暖系统是比较经济的；对于初投资值很大的决定性因素是较高的太阳能集热器价格，因此降低太阳能集热器价格将有利于太阳能供暖系统的推广。
The economy of solar energy combined heating network floor radiation heating system which used in a typical room in Shenyang is analyzed, including the system’s initial investment and annual cost, etc., providing a reference for study and promotion of solar energy heating system. A typical room 71.52 m2 in Shenyang as an example, the “Solar Energy Floor Radiation Heating System Combined with Heating Network Calculation Software” is utilized to calculate the initial investment and other parameters. The typical solar heating systems’ initial investment, payback time etc., are analyzed. The economical pa-rameters, including the initial investment and annual cost of the typical system, are calculated with the soft-ware for a 71.25 m2 room in Shenyang. If the room uses the solar energy combined heating network floor radiation system, the initial investment value is about 30 000 to 50 000 yuan; Payback time is more than 10 years. For users in Shenyang, considering the residential income, the lower initial investment is more e-conomic for choose. High price of solar collector is the decisive factor of the high initial investment, lower-ing the price of solar collector will be good for improving the solar energy heating system.
