在房间里,人们吸入新鲜的空气而呼出二氧化碳,同时人体还散发热量、湿气.而室内的燃气用具(例如煤气灶、液化气灶、燃气热水器、燃气热泵等)工作时所产生的二氧化碳,水蒸气和散发的热量远比一个人的大得多,因此工作中的燃气用具污染室内空气,又使室温和空气温度升高,破坏了人的舒适感.尤其是当燃气用具发生不完全燃烧时,还会产生一氧化碳、二氧化碳、二氧化硫和氮氧化物等有害气体,危及人身安全.
In the room, people inhale fresh air and exhale carbon dioxide, while the body also emits calories and moisture.While indoor gas appliances (such as gas stoves, gas stoves, gas water heaters, gas heat pumps, etc.) work produces carbon dioxide, Water vapor and the heat emitted is much larger than a person, so the work of gas appliances pollute the indoor air, but also to room temperature and air temperature, undermining people’s comfort, especially when the gas appliance incomplete combustion When it will produce carbon monoxide, carbon dioxide, sulfur dioxide and nitrogen oxides and other harmful gases, endangering personal safety.
