摘　　要：充分利用太阳能和生物质能能够为建筑提供清洁能源,并且可解决严寒和寒冷地区传统供暖方式能耗高、效率低等问题,因此,本文提出一种以太阳能和生物质能作为热源的供暖系统,并对其进行性能分析。该系统运行采用太阳能单热源运行模式(模式一)和太阳能-生物质能双热源运行模式(模式二),用以应对不同的工况,并在南疆图木舒克市搭建试验平台进行测试。结果表明:模式一太阳能集热器和板式热交换器平均热效率分别为63.35%和81.38%,系统的能源效率为72.48%,火用效率为28.35%,模式二太阳能集热器和板式热交换器平均热效率分别为61.35.%和65.36%,生物质锅炉能源效率为78.69%,系统能源效率为68.67%,系统火用效率为26.39%。与传统的供暖系统相比,模式一的节能率高达96.19%,模式二的节能率达到59.09%;模式一的PMV为-0.5,模式二的PMV为-0.7,两种模式的热舒适性都良好。Making full use of solar energy and biomass energy can provide clean energy for buildings,which can improve the shortcomings of traditional heating methods such as high energy consumption and low efficiency in cold and cold areas.Therefore,this paper proposes a heating system with solar energy and biomass energy as heat source,and analyzes its performance.The system operates in a single solar heating mode(Mode 1)and a combined solar biomass heating mode(Mode 2)to cope with different working conditions and the test platform was built in Tumushuke city of southern Xinjiang.The results show that:In mode 1,the average thermal efficiency of solar collector and plate heat exchanger is 63.35%and 81.38%respectively,and the energy efficiency of the system is 72.48%and exergic efficiency is 28.35%.In Mode 2,the average thermal efficiency of solar collector and plate heat exchanger is 61.35%and 65.36%respectively,and the energy efficiency of biomass boiler is 78.69%,the energy efficiency of the system was 68.67%and the exergic efficiency was 26.39%.Compared with the traditional heating system,the energy saving rate of solar single heating mode is up to 96.19%,and the energy saving rate of solar combined biomass energy mode is up to 59.09%.The PMV of solar single heating mode is-0.5,the PMV of solar combined biomass energy mode is-0.7,and the two modes have good thermal comfort.
