温度湿度独立控制空调系统新风运行策略研究
Operation strategies of outdoor air for temperature & humidity independent processed air conditioning systems
摘要:
基于工业通风中的全面通风方程,类比得出室内空气含湿量模型。当使用温度湿度独立控制空调系统的办公建筑内无办公人员时,可将新风渗透湿负荷作为室内湿负荷的主要来源。结合案例,对比分析了含湿量模型理论计算值与Fluent软件模拟值,验证了含湿量模型的适用性,并采用该模型得出了不同新风含湿量下适宜的人均新风量和新风预除湿时间,有利于温度湿度独立控制空调系统新风机优化运行。
Abstract:
Based on the general ventilation equation of industrial ventilation, obtains the indoor air humidity ratio model by the analogical method. When the office building with temperature & humidity independent processed air conditioning system is not occupied, outdoor air moisture load by infiltration is the main source of indoor moisture load. Based on a case, compares the theoretical calculation results of the model and the simulation results of Fluent software, and verifies the practicability of the humidity ratio model. Determines the suitable outdoor air requirement per capita and the pre-dehumidification time of outdoor air under different outdoor air humidity ratios using the model, which is favorable to carry out optimal operation of outdoor air handling units for temperature & humidity independent processed air conditioning systems.
