浅谈水源热泵多联机系统设计要点

Design Essential of Water Source Multi-connected Air-conditioning System

水源热泵多联机系统与传统风冷多联机的制冷/热原理相似,区别在于室外机的换热介质不同。由于受建筑屋面摆放的限制及不同气候区风冷冷热源温度的限制,加之水源热泵系统较高的能效,一些工程中水源多联机系统的优势较为明显;文章以南京某办公楼的水源多联机系统为例,分析水源热泵系统的设计要点,明确指出设计及工程中应满足水源热泵多联机最小水量的要求。

The Water-Source Multi-Connected Air-Conditioning System has a similar cooling/heating mechanism as the traditional Wind-Source Multi-Connected Air-Conditioning System. One difference is that the two systems use different heat transfer mediums for their outdoor unit airconditioners. The advantage of Water-Source Multi-Connected Air-Conditioning System is obvious in engineering application projects. First of all, the Water-Source Multi-Connected Air-Conditioning System has higher energy efficiency. Moreover, the Wind-Source Multi-Connected Air-Conditioning System has some limitations: the installation of Wind-Source Multi-Connected Air-Conditioning System system usually requires large roof area;the temperature limitation for wind cooling and heating source in different climate zones for Wind-Source Multi-Connected Air-Conditioning System system.One Water-Source Multi-Connected Air-Conditioning System used in an office building in Nanjing, China was selected as an example in this article. The design essentials of the Water-Source Multi-Connected Air-Conditioning System was analyzed. Our conclusion is that the design process for engineering application should consider that the minimum water flow requirement should be satisfied for the Water-Source Multi-Connected Air-Conditioning System.
