摘　　要：太阳能烟囱是一种热压作用下的自然通风设备,它利用太阳辐射作为动力,为空气流动提供浮升力,将热能转化为动能。露点间接蒸发冷却技术利用空气的干球温度和不断降低的湿球温度之差进行换热,可以将空气温度冷却到低于环境湿球温度且接近露点温度。本文介绍了太阳能烟囱与露点间接蒸发冷却技术的研究现状,提出一套太阳能烟囱与露点间接蒸发冷却复合的空调节能系统。分析表明,该系统可合理的利用太阳能解决室内通风降温问题,投资和运行费用都很低,节能环保效果显著。Solar chimney is a kind of natural ventilation application under the action of hot pressing,it using solar radiation as power,providing buoyancy lift for air flow,transfer the thermal energy into kinetic energy.The technology of dew-point evaporative cooling using the temperature difference of air between dry bulb temperature and lowing wet bulb temperature to transfer heat.Its able to cool air to temperature below ambient wet bulb temperature and approaching dew-point temperature.This paper review the research status of solar chimney and dew-point evaporative cooling.The analysis results showed that the proposed system is a reasonable way to solve the indoor ventilation and cooling problems.its investment and operating cost is lower,and has a remarkable energy saving and environment protection effect.
