这里讨论的是不用压缩机的冷风器,它是借助于水蒸发时吸热的原理制冷的。冷风器的结构如图1所示,由冷风器的吸气口吸入的混浊的室内热空气,首先通过吸气口的空气过滤器,然后又通过水洗式过滤器除去空气中的尘埃和烟气,同时被加湿到接近于饱和状态。由于开始时,水温比空气的温度低,所以水籍中的水不断地吸收由空气传来的热量,其本身的温度逐渐上升。但由于水的蒸发吸收了水的热量而使水的温度又下降,所以 Discussed here is the compressor without the air cooler, which is based on the principle of heat absorption water evaporation refrigeration. The structure of the air cooler as shown in Figure 1, the air intake by the cooler inlet cloudy indoor hot air, first through the air inlet filter, and then through the water filter to remove airborne dust and flue gas , While being humidified to near saturation. Since the beginning of the water temperature is lower than the temperature of the air, so water in the water constantly absorb the heat from the air, its own temperature gradually increased. However, due to water evaporation to absorb the heat of water and water temperature dropped again
