在美国丹佛市召开的一次讨论会上,专家们指出R717(氨)由于其热力性能较好,而且不破坏臭氧层,将在空调系统中得到更多的应用。 一种建议的设计思想是设置密闭的披屋作为机房和设备间,其中装有感应器,如何有氨泄漏发生,感应器启动风扇,将氨抽出披屋,向上扩散,并远离周围的建筑物;另一种设计思想是采用闪烁设备来分解氨气,使浓度降到低值。ASHRAE有一个研究项目(682—RP)正在进行,他们通过采用一种开放式的立管燃烧器和一个连续流动的燃烧器来研究氨的可燃极限(燃烧的氨气比例)和燃烧性能。研究者想搞清如何使故意由制冷系统放出的氨引燃,并在火焰中燃烧;
At a seminar in Denver, USA, experts pointed out that R717 (ammonia) will find more applications in air conditioning systems due to its better thermal performance and without damaging the ozone layer. One proposed design idea is to set up a closed phreatic house as a room and equipment room, where sensors are installed, how ammonia leaks occur, sensors start the fan, draw ammonia out of the phyla, upwards and away from the surrounding buildings Another design idea is to use a flashing device to decompose ammonia to bring the concentration down to a low level. ASHRAE has a research project (682-RP) under way to study the flammability limit (combustion ammonia ratio) and combustion performance of ammonia using an open riser burner and a continuous flow burner. The researchers wanted to find out how to ignite the ammonia that is deliberately released from the refrigeration system and burn it in the flames.
