为研究家用喷头的灭火性能和喷头动作后对室内环境的影响，分析了住宅设置自动喷水灭火系统的必要性，并以沙发作为点火源，在相同的喷水强度下开展了不同类型家用喷头和标准喷头的灭火性能对比试验。试验结果表明，采用家用喷头和标准喷头均能有效控火，但下垂型喷头的动作时间要早于边墙型喷头。在室内环境条件变化方面，采用家用喷头时较标准喷头在CO浓度方面减少较为明显，约减少59％；在O2浓度变化方面较采用标准喷头提高了0.6％，采用家用喷头较标准喷头能为人员疏散提供更好的环境。
為研究傢用噴頭的滅火性能和噴頭動作後對室內環境的影響，分析瞭住宅設置自動噴水滅火繫統的必要性，併以沙髮作為點火源，在相同的噴水彊度下開展瞭不同類型傢用噴頭和標準噴頭的滅火性能對比試驗。試驗結果錶明，採用傢用噴頭和標準噴頭均能有效控火，但下垂型噴頭的動作時間要早于邊牆型噴頭。在室內環境條件變化方麵，採用傢用噴頭時較標準噴頭在CO濃度方麵減少較為明顯，約減少59％；在O2濃度變化方麵較採用標準噴頭提高瞭0.6％，採用傢用噴頭較標準噴頭能為人員疏散提供更好的環境。

In order to study the fire control performance of residential sprinkler and the influence on environment after the activation of sprinklers, the necessity of setting sprinkler systems in the residence was introduced, and the comparative test on fire control performance of different types of residential sprinklers and standard sprinklers was conducted under the same water supply density.The results showed that both the residential sprinklers and the standard sprinklers could control the fire well, but the activated time of the pendent sprinkler was earlier than that of the sidewall sprinkler.In the aspect of environment condition variation, the concentration of CO was reduced a-bout 59 percent and the concentration of O2 was increased about 0 .6 percent when using the residential sprinklers comparing with the standard sprinklers, The better evacuation environment can be provided when using the residen-tial sprinklers.
