Research on Application of Integrated Refrigeration/heat Pump System Combined Solar and Traditional Energy in Houses

为实现太阳能在绿色节能建筑中的应用,根据别墅建筑特点,结合溴化锂吸收式制冷/热泵系统的特点,提出太阳能与常规能源复合的空调/热泵系统。系统内采用了潜能储存和常规蓄能综合技术,提高了系统的蓄能密度,并解决了吸收式热泵系统运行必须有16℃以上热源的问题。系统可为别墅建筑提供夏季空调,冬季采暖以及全年的卫生用水。建立了太阳能综合系统运行特性分析的计算模型,并以北京、西安、兰州三处太阳能较为丰富的地区为例,结合气候条件对系统运行特性进行了计算分析,给出了系统内能量分配与平衡的关系,并对系统运行作了简要的经济性评价。

In order to realize the solar energy application in houses, an integrated refrigerating/heat pump system combined solar and traditional energy was proposed, which can supply air- conditioning, heating, and hot water for houses. Adopting the refrigerating/heating potential storage technology （R/HPST） coupled with common thermal energy storage technology, the energy storage capacity of the integrated system rises and the requirement of the heat resource temperature being above 16℃ can be met. The calculation analysis models of the integrated system operation characteristics were set up. Taking Beijing, Xi＇an, and Lanzhou as the system operation districts where solar energy is abundant, the system operation process was simulated and its characteristic was analyzed according to the local weather condition. Moreover, the relation of energy distribution to energy balance in the system operation process was discussed. Finally, a simple economic estimation of the integrated system operation was performed.
