火墙系统包括炉灶(或火炉)、火墙、烟囱,作为一种建筑传统供暖系统,近年来,依然是新疆大部分农村地区民居采用的主要供暖形式。目前使用的火墙,建造多以经验为指导,性能参差不齐,普遍存在排烟温度高,能耗大,能源利用率低的缺点。本文针对上述缺点,提出了供暖火墙兼生活热水系统,即在原有火墙中加入了生活热水加热铜盘管。在不同室外温度下,满足室内热舒适性条件下,对该系统的能源利用率进行了实验研究并与传统火墙进行了对比。实验结果表明,供暖火墙兼生活热水系统的新式火墙能在保证室内热舒适性的同时又可以用烟气加热生活用水,降低了排烟温度,明显提高能源利用率,具有现实的推广和深入研究的意义。
火牆繫統包括爐竈(或火爐)、火牆、煙囪,作為一種建築傳統供暖繫統,近年來,依然是新疆大部分農村地區民居採用的主要供暖形式。目前使用的火牆,建造多以經驗為指導,性能參差不齊,普遍存在排煙溫度高,能耗大,能源利用率低的缺點。本文針對上述缺點,提齣瞭供暖火牆兼生活熱水繫統,即在原有火牆中加入瞭生活熱水加熱銅盤管。在不同室外溫度下,滿足室內熱舒適性條件下,對該繫統的能源利用率進行瞭實驗研究併與傳統火牆進行瞭對比。實驗結果錶明,供暖火牆兼生活熱水繫統的新式火牆能在保證室內熱舒適性的同時又可以用煙氣加熱生活用水,降低瞭排煙溫度,明顯提高能源利用率,具有現實的推廣和深入研究的意義。

The hot wall system includes a stove (or furnace), firewall, chimney, as one kind of building traditional heating system, in recent years, is still the main forms of supply heating in most of the Xinjiang rural area. For the moment, the wall construction based on mainly experience. and has large differences in performance, A common problem with hot wall is that:high temperature of exhaust gas, energy consumption, low energy utilization rate. This article in view of the above shortcomings, the hot wall and domestic hot water system is proposed, arrangementin the copper tube in the original wall as new system. At different outdoor temperatures and the indoor thermal comfort conditions needs, the energy efficiency of new system were studied and compared with the traditional hot wall. The experimental results show that, the new hot wall and domestic hot water system can ensure indoor thermal comfort at the same time can heat domestic water use flue gas, reducing the exhaust gas temperature, the energy utilization rate is improved obviously. It is of certain significance to promotion and intensive study.
