Abstract
Flat Plate collector is the most common type of solar water heater, due to its low price, easy installation, and long life. The efficiency of a solar collector is key to evaluating its performance in thermal facilities, especially applications requiring low or medium temperatures. The most important factors affecting the efficiency of the solar collector are the weather conditions, the design of the collector, the type of work fluid used. A Flat plate collector tested experimentally in solar heating system worked by direct flow and closed system to heating space in Najaf, Iraq (32° 1' N / 44° 19' E). Experimental results showed that the overall daily efficiency of the collector reached 37.16%. Moreover, the maximum temperature of hot water for collector reached 57.1oC
平板集热器是最常见的太阳能热水器类型，由于其价格低，安装方便，寿命长。太阳能集热器的效率是评估其在热设施中性能的关键，特别是在需要低温或中温的应用中。影响太阳能集热器效率的最重要因素是天气条件、集热器的设计、所用工作流体的类型。在伊拉克Najaf(32°1' N / 44°19' E)采用直流式闭式供热系统对平板集热器进行了实验测试，实验结果表明，集热器的总日效率可达37.16%。集热器热水最高温度达到57.1℃
