摘要
燃气空调设备一般设计的排烟温度不低于110℃,如此高的排烟温度损失了大量可利用热量。本文计算了排烟温度为110℃时的烟气,在不同回收温度下可回收的热量及燃料利用提高率。以户式燃气空调为例,提出了两种回收利用排烟余热的方式:加热生活用水和加热燃烧用空气,分析了两种方式的特点,给出了一种烟气余热型热水系统。
The design temperature of gas-fired air-conditioner is up to 110℃ usually, so the heat loss is larger. The saving heat and the increased ratio of fuel utilizing by lowering the exhaust temperature were calculated in this paper. Taking the household gas-fired air-conditioner as an example, two recovering exhaust heat methods: heating water for living and air for combustion were discussed, the characteristics of them were analyzed, and the exhaust heat heating water system was presented.
