太阳能吸收式热泵利用的能源为清洁可再生的太阳能,对环境影响程度很小。基于8 000m2厂房冬季供暖的负荷设计,建立了太阳能吸收式热泵系统模型,并进行了性能分析。研究结果表明,太阳能吸收式热泵系统性能随发生器浓溶液出口温度、吸收器稀溶液出口温度以及吸收器压力的增加而增加,在给定范围内存在最优值。通过建立的多目标优化数学模型,获得了太阳能吸收式热泵系统评价函数VF,并找到最优工况。
Solar energy absorption heat pump to use energy for the clean renewable solar energy, little impact on the environment. Based on the load design of 8 000 m 2 plant heating in winter, a solar absorption heat pump system model was established and its performance was analyzed. The results show that the performance of the solar heat pump system increases with the exit temperature of the concentrated solution of the generator, the outlet temperature of the dilute solution and the pressure of the absorber, and has an optimal value within a given range. Through establishing the multi-objective optimization mathematical model, the evaluation function VF of solar heat pump system is obtained, and the optimal working condition is found.
