摘要:
空调室外干湿球温度参数同时作用于建筑物，是影响建筑热环境的重要参数，在空调系统设计中作为室内负荷计算和空调设备容量计算的初始计算气象条件.现阶段，空调室外计算干、湿球温度的确定方法主要是对单个气象参数的一维概率统计，而未考虑两者之间的同时发生性.因此，本文提出了一种二元超阈值模型的室外干湿球温度确定方法，对满足完全不保证率下的干、湿球温度进行求解计算，从而获得同时发生的室外干湿球温度参数.该方法为空调系统的设计参数提供了一种更为科学合理的确定方法.以乌鲁木齐为例，计算结果表明空调室外计算干、湿球温度值较我国方法均有所降低,较ASHRAE方法中的伴随参数有所增加.
Abstract:
As an important parameter affecting the building thermal environment, the air conditioning outdoor dry-bulb and wet-bulb temperature parameters also act on buildings simultaneously. In the design of the air conditioning system, they serve as the initial calculation meteorological conditions for indoor load calculation and air conditioning equipment capacity calculation. At present, the method of determining the design dry-bulb and wet-bulb temperatures of air conditioning mainly concentrates on onedimensional probability statistics of a single meteorological parameter, but does not consider the simultaneous occurrence of the two. Therefore, this paper proposes a method to determine the design outdoor dry-bulb and wet-bulb temperatures based on the binary super-threshold model. The coincident design dry-bulb and wet-bulb temperatures which satisfy the completely non-guarantee rate can be calculated. This method provides a more scientific and reasonable determination method for the design parameter calculation of air conditioning system. Taking Urumqi as an example, the results show that, compared with Chinese method, the calculated values of design dry-and wet-bulb temperature are lower, and compared with ASHRAE method, the adjoint parameters are increased.
