使用TRNSYS建立了非直膨式太阳能热泵热水系统的仿真模型,选取上海地区的气象数据,在给定用户热水负荷的前提下,以系统运行能耗为优化目标,以太阳能集热器面积、集热水箱体积和生活热水箱体积为优化变量,采用遗传算法对该系统进行了优化研究,获得了系统运行能耗最小时各变量的优化值,为非直膨式太阳能热泵热水系统优化设计提供了理论依据。
Using TRNSYS to establish the simulation model of non-direct expansion solar heat pump hot water system, select the meteorological data of Shanghai, under the premise of the hot water load of the user, take the system operation energy consumption as the optimization goal, take the solar collector area , Hot water tank volume and domestic hot water tank volume as optimization variables, and the genetic algorithm was used to optimize the system to obtain the optimal value of each variable when the system operating energy consumption is the smallest. It is a non-direct-expansion solar heat pump hot water System optimization design provides a theoretical basis.
