摘　　要：提出了1种利用微热管阵列高效传热实现回风加热新风的热电热回收装置。在焓差实验室中搭建了新型热电热回收新风装置的性能测试平台,实验研究了热回收装置性能,并对其影响因素进行了分析。结果表明,实验在新风量为280 m^(3)/h,新风进风温度为10℃,输入电功率为550 W的工况下新风温升达到最大值10.87℃;新风进风温度为0℃,输入电功率为550 W的工况下装置制热量达到最大值1255.8 W。实验工况的能量回收比在1.87~12.48之间变化。输入电功率每增加50 W,出口温度约增加0.63℃,能量回收比随之快速降低;新风进风温度每降低1℃,出风温度降低0.8℃,制热量和ERC增大;风量从110 m^(3)/h增加至280 m^(3)/h时,制热量和ERC增大,出风温度降低7.5℃,同时压降也增大了47.32 Pa。分析装置的传热机理后以实验数据为样本拟合了送风温度与进风温度和输入电功率之间的关系式,为其实际工程应用提供了理论参考。研究结果为实现新风节能供应提供了技术支持,也为建筑减少运行能耗与碳排放提供了新的思路。A thermoelectric heat recovery device,which uses a micro heat pipe array to realize efficient heat transfer to heat the return air to heat the fresh air,was proposed.In the enthalpy difference laboratory,the performance test platform of a new type of heat and heat recovery fresh air device was built to study the performance of the heat recovery device,and analyze its influencing factors.The results show that the fresh air volume is 280 m^(3)/h.The temperature rise of fresh air reaches the maximum value of 10.87℃under a inlet air temperature of 10℃and the input electric power of 550 W.Under a fresh air inlet temperature of 0℃and input electric power of 550 W,the maximum heating capacity of the device reaches 1255.8 W.The energy recovery ratio of the experimental conditions varies from 1.87 to 12.48.When the input power increases by 50 W,the outlet temperature increases by about 0.63℃,and the energy recovery ratio decreases rapidly.When the inlet temperature of fresh air decreases by 1℃,the outlet temperature decreases by 0.8℃,and the heating capacity and ERC increase.When air volume from 110 m^(3)/h increased to 280 m^(3)/h,the heating capacity and ERC increase,the outlet temperature decreases by 7.5℃,and the pressure drop also increases by 47.32 Pa.After analyzing the heat transfer mechanism of the device,the relationship between the supply air temperature,the inlet air temperature,and the input electrical power was fitted using experimental data as samples,providing a theoretical reference for its practical engineering application.The research results provide technical support for achieving energy-efficient supply of fresh air,and new ideas for buildings to reduce operational energy consumption and carbon emissions.
