摘要
介绍了地板辐射系统的特点,对比分析了不同供冷/供热末端装置的经济性,提出了一种新的供冷/供暖系统评价指标——单位耗供冷/供热系数ε。利用分析法对地板辐射供冷/供暖系统与风机盘管系统和散热器系统进行了比较,结果表明,地板辐射供冷比风机盘管供冷单位耗供冷系数提高133%,地板辐射供暖比散热器供暖单位耗供热系数提高41%。
Presents the characteristics of the floor radiant system,compares the economic performance of different cooling/heating terminal devices,and puts forward a new evaluation index for the cooling/heating system—cooling/heating coefficient per exergy consumptionε。By comparing the floor radiant heating/cooling system to fan coil systems for cooling and radiator systems for heating respectively using the exergy analysis method,concludes that theεof the floor radiant cooling system increases by 133% than that of the fan coil system,and theεof the floor radiant heating system increases by 41%than that of the radiator system.
