太阳能空气集热控制系统的研究

太阳能空气集热采暖系统作为一种简单有效的太阳能应用方式，渐渐引起了世界各国学者的广泛关注。然而，由于太阳能空气采暖的热源是太阳能，建筑室内环境很容易受室外天气影响，这使得建筑的热性能具有不确定性，为了解决上述问题，文中以单片机为控制核心，以温度、太阳辐射照度为输入参数，采用PID方法控制风机启闭及转速，获取最佳的风机运行状态，提高系统的供热效果及效率。

Study on Solar Air Collector Control System

Solar air heating system as a simple and effective way of solar energy application has attracted wide attention of scholars around the world. However, due to the heat source is solar energy solar air heating, indoor environment is very vulnerable to the outdoor weather, which makes the thermal performance of building is uncertain, in order to solve the above problem, this paper uses microcontroller as the control core, using temperature, solar radiation intensity as input parameters, using PID method to control the fan of opening, closing and speed, to obtain the wind machine optimum operation state, and improve the efficiency of the heating and effect of the system.
