电辅助太阳能相变蓄热供热控制系统研究

Research on the Control System of Phase Change Thermal Storage of Solar Energy

研究了独立民居太阳能供热的控制系统,为了克服太阳能白天采集与用户晚上使用的矛盾如何采用相变蓄热材料进行蓄热,如何为了弥补阴天太阳能获取的不可及性采用电辅助加热,从而对系统中的水泵、电动调节阀、辅助电热器等设备的运行过程进行自动控制,以达到室内温度的要求.

In this paper, the control system of independent residential heating using solar energy is studied. In order to overcome the contradiction between solar energy collection in the daytime and using in the evening,the phase-change heat storage materials are used to store heat, so as to make up for the unavailability of solar acquisition on cloudy days by using electric auxiliary heating. As a result,the system automatically controls the operation process of pump, electronic valve,auxiliary electric heater and other equipments to meet the requirement of indoor temperature.
