摘　　要：为解决对流换热采暖上热下冷的温度分层现象和传统辐射采暖能源利用率低的问题,基于燃气催化燃烧技术设计研发了适用于高大空间工业建筑的新型红外辐射供暖设备。首先介绍了催化红外辐射供暖设备原理,随后提出了该设备的性能评价指标并对其性能进行试验研究。试验结果表明:该设备表面辐射温度范围为400~450℃,最大温度不均匀度为3.15%;其红外辐射波长范围为2~25μm,红外发射光谱与人体中脂肪和蛋白质的吸收光谱相匹配,供热效率高。团队自主研发的Pt/Al_(2)O_(3)催化剂可显著降低天然气的起燃温度至120℃,同时实现了超过98%的燃料转化率,证明了催化剂的高活化性能。在稳定性方面,连续燃烧8 040 h未发现明显烧结和失活。最后将该设备应用于夏热冬冷地区高大空间工业建筑进行冬季供暖性能实测,结果表明:该设备可保证室内16~20℃的热环境,坐姿头脚最大垂直温差为2.56℃,处于辐射范围内的人体部位可以得到有效加热。设备开启10 min后,受试者热感觉投票由“稍冷”趋向“稍暖”,热舒适投票由“稍不舒适”趋向“完全舒适”,该设备可较快改善人员主观感受。该设备采暖季系统造价费用为148.51元/m^(2),运行费用为38.93元/m^(2)。A new piece of infrared radiant heating equipment based on gas catalytic combustion technology was designed for lofty and spacious industrial buildings in order to address the issues of temperature stratification of convective heat exchange heating and low energy utilization of traditional radiant heating. First of all, after a description of the principle behind catalytic infrared radiant heating equipment, indicators for the performance evaluation of the equipment were presented, and its performance was studied experimentally. The experimental results demonstrated that the surface radiation temperature of the equipment ranges from 400 ℃ to 450 ℃ with a maximum temperature non-uniformity of 3.15%. The wavelength range of infrared radiation spans from 2 to 25 μm, aligning with the absorption spectrum of fat and protein in human bodies, thereby ensuring high heating efficiency. The Pt/Al_2O_3 catalyst independently developed by the team can achieve a fuel conversion rate of over 98% and significantly lower the natural gas ignition temperature to 120 ℃, confirming the outstanding activation performance of the catalyst. After continuous burning for 8,040 hours, no significant sintering or deactivation was observed in terms of stability. During winter, the equipment was utilized to measure heating performance in lofty and spacious industrial buildings located in areas with hot summers and cold winters. The results indicated that the equipment is capable of providing an indoor thermal environment at a temperature ranging from 16 ℃ to 20 ℃, with a vertical temperature difference between the head and feet in a seated position reaching up to 2.56 ℃, enabling human body parts within the radiation range to be effectively heated. After the device had been on for 10 minutes, the subjects' thermal sensation vote shifted from being “slightly cold” to “slightly warm”, and their thermal comfort vote moved from being “slightly uncomfortable” to “completely comfortable”. This device can quickly enhance
