摘　　要：近些年来,我国设施农业发展的如火如荼,温室大棚建筑能耗不断增加。采用TRNSYS软件,对使用空气源热泵与水蓄热供暖系统的温室大棚的供暖温度、运行功率及运行费用进行仿真模拟分析。提出了谷价蓄热、平价蓄热、无蓄热3种蓄热策略,并利用峰谷电价实现电网的“削峰填谷”,降低峰电价时段的用电负荷,降低供暖系统运行费用。根据3种不同控制策略的仿真模拟分析得出的结果及经济性分析可以发现,谷价蓄热策略相比于平价蓄热策略及无蓄热策略的供暖季运行费用分别降低了30.8%和19.6%。同时从经济性分析来看,谷价蓄热策略年度费用为3种控制策略中最低,经济性最优。该研究为空气源热泵与水蓄热供暖系统为以后在温室大棚中的应用提供相应的参考。In recent years,with the development of facility agriculture in full swing,China's greenhouse building energy consumption is increasing.This paper,based on TRN-SYS software,performs a simulative analysis of the heating temperature,operating power and operating cost when air source heat pump and water storage heating system are used to heat the greenhouse.This paper puts forward three heat storage strategies:valley price heat storage,usual electricity price and heat storage strategy,and no heat storage,and how to use peak vally electricity price to realize peak load shifting of power grid,reduce electricity load during peak electricity price and the operating cost of heating system.According to the simulation analysis results of three different strategies,it can be found that the running cost of the valley price heat storage strategy is 30.8%and 19.6%lower than the usual electricity price and heat storage strategy and no heat storage strategy respectively.At the same time,from the perspective of economic analysis,the annual cost of valley price heat storage strategy is the lowest,and the economy is the best.This study provides a reference for the application of air source heat pump and water thermal storage heating system in greenhouse.
