本文将变风量空调系统与多联机系统相结合组成复合空调系统,解决多联机系统缺乏新风的问题,同时可利用两种系统各自的优点。以复合空调系统的仿真平台为基础,在变工况条件下研究了其温湿度控制特性,并针对新风处理后的状态提出了几种控制策略。结果表明,该系统在保持高能效优点的同时,解决了多联机系统缺乏新风的问题,且在实现室内温湿度解耦控制方面具有一定的潜力。
In this paper, variable air volume air conditioning system combined with multi-line system to form composite air conditioning system to solve the problem of multi-line system lack of fresh air, while taking advantage of the respective advantages of the two systems. Based on the simulation platform of the composite air conditioning system, the temperature and humidity control characteristics are studied under varying working conditions. Several control strategies are proposed according to the fresh air treatment status. The results show that this system can solve the problem of lack of fresh air in the multi-connected system while maintaining the advantages of high energy efficiency and has certain potential in the control of indoor temperature and humidity.
