复合式空气源热泵在学校中应用的设计分析

Application of Compound Air Source Heat Pump System in Schools

在对学校建筑负荷特点及使用情况进行分析的基础上,提出以常规热源作为调峰热源的双泵双通道复合式空气源热泵系统。先根据建筑使用特点,将运行工况分为日间(6:00^-21:00)和夜间(21:00~6:00)两种工况,然后用综合费用最优法确定日间运行时段的最佳调峰比例,以确定复合系统的最优设计方案。最后将常规系统和带有调峰热源的双泵双通道复合式空气源热泵系统各项费用进行对比分析。

On the basis of the analysis of the load characteristics and application situation of the school building,a double-pump and double-channel compound air source heat pump system with conventional heat source as peak-shaving heat source is proposed.Firstly,the operating conditions are divided into daytime(6:00~21:00)and nighttime(21:00~6:00)according to the characteristics of building use.Then,the optimal peak-clipping proportion of daytime operation period is determined by the optimal comprehensive cost method to determine the optimal design scheme of the compound system.Finally,the costs of the conventional system and the double-pump and double-channel compound air source heat pump system with peak-regulating heat source are compared and analyzed.
