主动式太阳房采暖系统节能控制策略研究

Study on Energy-saving Control Strategy of Active Solar House Heating System

主动式太阳房水加热采暖系统,是利用温室原理将太阳能转变为热能,并通过水温向室内传递热量,从而提升室内温度的一种装置。文章以酒泉地区主动式太阳房水加热采暖系统为例,通过系统的控制方法及运行过程分析,提出了主动式太阳房电辅助加热型水加热采暖系统的优化控制策略,通过改进控制算法,在确保采暖时间、采暖温度不变的前提下,使太阳能的利用效率得到大幅提升,全年采暖节约电能约38.8%。

Active solar house water heating system is a device that uses the principle of greenhouse to convert solar energy into heat energy,and transfer heat to indoor through water temperature,so as to raise indoor temperature.Taking the active solar house water heating system in Jiuquan area as an example,through the analysis of the control method and operation process of the system,the author put forward the optimal control strategy of the active solar house electric-assisted heating water heating system.By improving the control algorithm,under the premise of ensuring the heating time and heating temperature unchanged,the utilization efficiency of solar energy has been greatly improved.Heating saves about 38.8% of electricity in the whole year.
