Research on cold bridge prevention and control technology for VRV air conditioning system- Taking the Qingpu Lian Shi Elderly Care Home project as an example
VRV空调系统冷桥防控技术研究——以青浦联实养老院项目为例

摘要

冷桥现象是VRV空调系统运行中的关键问题，易引发冷量损耗、管道锈蚀及室内环境破坏，对养老院这类对温湿度与环境稳定性要求严苛的场所影响尤为显著[1]。本文以青浦联实养老院VRV空调系统采购及安装项目为研究对象，聚焦冷桥防控技术展开研究。通过分析冷桥形成机理与传统防控痛点，重点阐述木垫式管支架与吊架的技术方案，包括材料选型、防腐处理、安装工艺等核心内容，并结合项目实践成果验证技术有效性[2]。研究表明，该冷桥防控技术可有效阻断冷量传递路径，避免结露问题，同时降低系统能耗与维护成本，为同类公共建筑VRV系统冷桥防控提供实践参考。

Abstract

The cold bridge phenomenon is a key issue in the operation of VRV air conditioning systems, which is prone to cause cooling loss, pipeline corrosion, and damage to the indoor environment. It has a particularly significant impact on places such as nursing homes, which have stringent requirements for temperature, humidity, and environmental stability [1]. This paper takes the procurement and installation project of the VRV air conditioning system at Qingpu Lianshi Nursing Home as the research object, focusing on the research of cold bridge prevention and control technology. By analyzing the formation mechanism of cold bridges and traditional prevention and control pain points, this paper focuses on the technical solutions of wooden pad-type pipe supports and hangers, including material selection, anti-corrosion treatment, installation process, and other core contents. The effectiveness of the technology is verified through project practice results [2]. The research shows that this cold bridge prevention and control technology can effectively block the cooling transmission path, avoid condensation problems, and reduce system energy consumption and maintenance costs, providing practical reference for the prevention and control of cold bridges in similar public building VRV systems.
