摘　　要：风冷专用空调冷媒管管长对制冷衰减量有着重要影响,有些老旧通信机房受制于建筑本身制约,不得不采用长管路设计,然行业内尚没有长管路下的设计标准或指南,对系统设计带来一定困难。本文通过某通信机房的空调设计与分析,并借鉴多联机设计思路和方法,提出了风冷专用空调长管路下的设计方法,为类似项目提供设计参考。The length of the refrigerant piping of air-cooled direct expansion air conditioner has an important influence on the cooling capacity. Some telecommunication buildings have to use the long refrigerant piping due to some reasons,but currently there is no any design specifications to have relevant description, which brings difficulty for the designer. In this paper, through the system design of air conditioner for certain telecommunication building with the long refrigerant piping, the design method is proposed by referring to the design method of the VRV, which provides the design reference for similar projects.
