模块化贮热水罐与直热式空气源热泵系统应用分析

Application analysis of the modular storage hot water tank and direct heating air source heat pump system

模块化贮热水罐相比于传统的大容积的贮热水罐有着安装灵活、热水利用率高等优势。在建筑集中供应热水系统中,模块化贮热水罐与直热式或循环式空气源热泵搭配可组成不同形式的热水供应系统,其控制原理以及热水利用率等均有不同,通过分析对比系统形式、COP值、控制原理以及全周期费用等方面,得出模块化贮热水罐与直热式空气源热泵组合具有安装维护方便、COP值高、控制简单以及全周期费用低等优势的结论。

The modular storage hot water tank has the advantages of flexible installation and high utilization of hot water, compared to traditional large volume storage hot water tank. In a building central heating water system, it is different in the control principle and hot water utilization for The modular storage hot water tank collocation with air source heat pump system for direct heat or circular heat. By analyzing and comparing the system form, COP value, control principle and full cycle cost, it is concluded that the combination of modular hot water storage tank and direct heating air source heat pump has the advantages of convenient installation and maintenance, high COP value, simple control and low full cycle cost.
