MULTI-OBJECTIVE OPTIMIZATION OF PHOTOVOLTAIC CURTAIN WALL ASSISTED DUAL-SOURCE HEAT PUMP SYSTEM IN DIFFERENT REGIONS
To overcome the limitation of single renewable energy applications in cold regions,a photovoltaic curtain wall assisted dual-source heat pump system is proposed.A system simulation model was established by TRNSYS.Taking the energy consumption and life cycle cost of the system as objective functions,the multi-objective optimization design of the configuration scale of the proposed system in different regions was carried out by using non-dominated sorting genetic algorithm(NSGA-Ⅱ),and the equilibrium solution was determined by using weighted sum method.The results show that the energy consumption of the optimized system in Harbin,Changchun and Shenyang increases by 5.9%,5.0%and 3.9%,respectively,and the life cycle cost decreases by 13.6%,17.1%and 12.9%.Compared with single objective optimization,multi-objective optimization can significantly reduce the life cycle cost while taking into account the performance,and has obvious advantages.
