多联机空调系统设计问题探析

Analysis on the Design of Multi-split Air Conditioning System

随着经济社会的迅速发展,城镇化水平日益增加,城市的建筑物为城市面貌的提升贡献了很大的力量,人们对居住舒适度的要求也与日俱增,空调已经成为建筑房屋的基本电器设备,显著的改善了生活居住舒适度,提高了人们的生活质量。与传统中央空调系统相比多联机空调系统具有简单的安装方式和灵活的使用方法的显著特征,同时不需专门的制冷机房及值班人员,节省了空间及运行成本。该系统可根据用户投资、装潢等不同使用需求分区、分期、分批安装及使用。文章研究的目的在于通过分析多联机空调系统原理,进一步提出多联机空调系统在工程设计中应注意的基本问题,方便设计师进行多联机空调系统的设计与应用。研究的方法主要是文献分析结合工作实际经验总结两种方法,对多联机空调系统的原理和特点进行了详细的分析,并结合工作实践经验探讨相关要点。最终分析认为多联机系统设计的时候需要注意设计程序、空调负荷计算、机组性能系数和气候条件、新风问题、室外机布置等方面的问题。通过分析可知,目前,空调系统的设计随着建筑物的要求不同而呈现多样化的趋势,只有为满足建筑物自身需要而有针对性的设计的空调系统才能充分的满足业主需要,并符合健康、绿色节能和环境保护多重标准。在目前的空调设计中,多联机空调系统则更为常见,成为大多数建筑物的首选空调系统设计方案。

With the rapid development of the economy and society,the urbanization level is increasing,and the urban buildings contribute a great force to the improvement of the city's appearance,and the demand for living comfort is increasing.The air conditioning has become the basic electrical equipment of the buildings,which has greatly improved the living comfort and people's quality of life.Compared with the traditional central air conditioning system,the multi-split air conditioning system has the features of simple installation and flexible operation methods,and no special refrigeration machine room and duty personnel are required,which saves space and operation cost.According to user investment,decoration and other different use requirements,the system can be installed and used in batches.The purpose of this paper is to analyze the principle of multi-split air conditioning system,and further put forward the basic problems that should be paid attention to in engineering design of multi-split air conditioning system,so as to facilitate designers to design and apply multi-split air conditioning system.The research method is mainly literature analysis and practical experience summary of two methods,the principle and characteristics of multi-split air conditioning system are analyzed in detail,and the related key points are discussed in combination with the working practice experience.Finally,it is considered that attention should be paid to the design program,air conditioning load calculation,unit performance coefficient and climate conditions,fresh air problem,outdoor unit arrangement and so on.Through the analysis,it can be seen that the design of air conditioning system shows a diversified trend with the different requirements of buildings at present.Only the air conditioning system designed to meet the needs of the building itself can fully meet the needs of owners and meet the multiple standards of health,green energy saving and environmental protection.In the current air conditioning design,multi-split air conditioning system is more common,which has become the preferred air conditioning system design scheme for most buildings.
