本文提出了用综合得热法确定客车夏季空调外气计算参数的方法。论述了客车空调外气计算参数可以利用建筑空调的气象统计资料,以湿球温度平均每年50小时的不保证时间为依据来确定。由于外气参数与空调负荷密切相关,据此可定出外气参数的计算区段。通过对空调客车的综合得热量的计算和分析看出,用武汉地区的外气参数作为我国客车空调的夏季外气计算参数是比较合适的。在客车空调负荷(按不稳定传热计算)的各种计算方法中,都可以采用本文提供的夏季外气计算参数及车体各壁面的太阳辐射强度的逐时值。
In this paper, a method of determining the calculation parameters of bus summer air conditioning outside air by the integrated heat gain method is proposed. Discusses the passenger air-conditioned air outside the calculation parameters can make use of building air-conditioning meteorological statistics, wet bulb temperature average of 50 hours per year is not guaranteed time to determine. As the outside air parameters and air conditioning load are closely related, according to which can be calculated outside the parameters of the calculation section. Through the calculation and analysis of the integrated heat gain of air-conditioned buses, it is found that it is more appropriate to use the outside air parameters of Wuhan as the calculation parameters of the summer air outside China’s bus air-conditioners. In passenger air-conditioning load (according to the unsteady heat transfer calculation) of the various calculation methods, can be used in this paper to provide summer air calculation parameters and the body wall of the solar radiation intensity of the hourly value.
