摘要

本文研究了一种集成太阳能吸收系统。它由真空管集热器、辅助加热器、储罐和溴化锂吸收式冷水机组成。该系统在四月至九月期间每小时进行一次。研究考虑了发电机温度、储罐容积和太阳能集热器面积等变量。采用优化方法，从能量、能量和经济角度寻找最佳点。采用TOPSIS方法，在发电机温度为100℃，储罐容积为3.1 m3，集热器面积为30 m2时获得最佳点。

Multi-objective optimisation of a transient solar absorption chiller from energetic, exergetic, and economic viewpoints

An integrated solar absorption system is investigated in the present study. It consists of evacuated tube collectors, an auxiliary heater, a storage tank, and a LiBr-water absorption chiller. The system is conducted hourly from April to September. Variables of generator temperature, storage tank volume, and solar collector area are considered for the investigation. An optimisation method is performed to find the optimum point from energetic, exergetic, and economic viewpoints. By using the TOPSIS method, the optimum point is obtained at a generator temperature of 100°C, storage tank volume of 3.1 m3, and collector area of 30 m2.
