为解决室外太阳灶使用条件恶劣及性能不稳定等问题,同时考虑到太阳能热水系统存在夏季热量过剩、冬季热量不足等天气条件制约,提出室内太阳灶耦合太阳能热水的热量梯级利用系统。通过实验研究可知,该系统在满足生活热水需求的同时,能收集中温热并将其存储在储热箱中,既可用于烹调,也可用于加热水,实现了太阳能中低温的梯级利用。 In order to solve the harsh conditions of the outdoor solar cookers and the instability of performance, taking into account the existence of solar hot water system overheating in summer, lack of heat in winter and other weather conditions constraints, proposed indoor solar hot water cascade solar thermal cascade utilization system. Through the experimental study shows that the system can meet the needs of domestic hot water at the same time, it can be collected and stored in the heat storage tank, both for cooking, but also can be used to heat water to achieve a solar cascade use of low temperature .
