多联式空调系统新风方式分析

本文对目前多联式空调系统的各种新风处理方式进行了分析，指出在实际应用中存在的问题。并结合工程设计实例介绍了确定新风方式的方法，阐明应根据建筑物的结构、功能和业主的要求等方面选择合适的新风方式，通过设计和校核计算保证新风量和空调房间的温湿度要求。同时建议相关的厂家开发专用于多联式空调系统的新风机组，其末端设备的最大冷风比应达到56kJ／kg左右。

Analysis of Fresh-Air for Multi-Connected Air-Conditioner Unit

In the article, every kind of current fresh-air methods of multi-connected air-conditioner unit was analyzed. The problems existed in application were put forward. Combining a building example, the determination of methods of fresh-air was presented. The appropriate fresh-air methods were chosen according to the request of the construction, functions of the building and owner, etc, and fresh-air rate, the temperature humidity request of the air condition room were ensured through calculation of design and proof, It is suggested that the related company should design fresh-air handling unit for multi-connected air-conditioner unit which the biggest ratio of cooling capacity and air flow was approximately 56 kJ/kg.
