苏联格里米特林等提出用室内气流组织效率(西德称之为投入能量利用系数)等四个量来评价室内空气分布系统的性能,使这种评价有了客观性,十分有利于改进设计和进行现场调试。 1.计算工作区内空气温度和速度的平均值t_(cp)、V_(cpo)具体是由各测点上测得的温度、速度求算术平均值,即为t_(cp),V_(cpo)。 t_(cp)=Σt_x/n v_(cp)=Σv_x/n 式中 n——具体测点数, t_x、V_x——该点测得的温度及速度。 2.计算工作区内空气温度、速度的均方根偏差值σ_t,σ_v。
The Soviet Union’s Grimitrin et al. proposed to evaluate the performance of the indoor air distribution system by using four factors such as the efficiency of indoor air flow organization (called the input energy utilization factor in West Germany), which made this evaluation objective and greatly facilitated the improvement. Design and conduct on-site commissioning. 1. Calculate the average value of air temperature and speed in the work area t_(cp), V_(cpo) Calculate the arithmetic mean value of temperature and speed measured at each measuring point, which is t_(cp), V_(cpo ). T_(cp)=Σt_x/n v_(cp)=Σv_x/n Where n is the number of measurement points, and t_x, V_x are the measured temperature and velocity at this point. 2. Calculate the RMS deviation σ_t, σ_v of air temperature and speed in the work area.
