《城镇燃气设计规范》(GB50028—93)中规定:独立居民小区和庭院燃气支管的计算流量宜按同时工作系数法计算(见规范第7.2.6条),其计算公式为: Q_h=k_t(ΣkNQ_n)式中:Q_h——燃气管道的计算流量(m~3/h); k_t——不同类型用户的同时工作系数; 当缺乏资料时,可取1; k——燃具同时工作系数,居民生活 用燃具可按附录F确定;
The “Specifications for Urban Gas Design” (GB50028-93) stipulates that the calculation flow of independent residential quarters and courtyard gas branch pipes shall be calculated according to the simultaneous work coefficient method (see Section 7.2.6 of the Rules), and its calculation formula is: Q_h=k_t ( ΣkNQ_n) where: Q_h—the calculated flow rate of the gas pipeline (m~3/h); k_t—simultaneous coefficient of operation for different types of users; when the data is lacking, it is desirable 1; k—the simultaneous coefficient of work of the burning appliances, residents Household appliances can be determined in accordance with Appendix F;
