一种可蓄热太阳能睡床结构及性能分析

介绍了一种兼具蓄热与散热两种状态的太阳能供暖用睡床。该睡床的下部为蓄热水箱，可从太阳能集热板获取热量供给睡床。研究了基于该睡床的供暖系统在北京地区的应用情况，并分析了不同状态下床板上表面的散热量与被褥内的温度。结果表明：在全天散热状态下，典型年供暖季集热器效率为37.7 %，复合型睡床的有效供热量为4 390.2 MJ，太阳能保证率为80.7 %；在白天保温−夜间散热下，集热器效率为33.1 %，复合型睡床的有效供热量为4 441.1 MJ，太阳能保证率为81.8 %。

Structure and performance analysis of a solar energy bed with heat storage

A kind of solar heating bed with heat storage and heat dissipation was introduced in this paper. A heat storage tank at the bottom of bed obtained heat from the solar collector plate to heat the bed. The application of integrated bed-based heating system in Beijing was introduced. The heat dissipation on the upper surface of bed plate and the temperature in the quilt under different conditions were analyzed. Results show that under the all-day heat dissipation mode, the collector efficiency in the typical annual heating season was 37.7%, while the effective heat supply of integrated bed and the solar fraction were 4 390.2 MJ and 80.7%, respectively. Under the mode of day-time heat storage and nighttime heat dissipation, the collector efficiency was 33.1% while the effective heat supply of integrated bed and the solar fraction were 4 441.1 MJ and 81.8%, respectively.
