热回收芯体的工作原理如图1所示，芯体1是以一透湿而不透气之湿热交换机能纸材，如纤维纸基材等作为隔板2，隔板2之间再设置具有多个气流入口3的波浪形板4，并且在室内侧I与室外侧II这些波浪形板4呈错开交叉排列，从而在芯体1内形成互不相通室内排气通道E-E及室外进气通道F-F，保证两股气流不会混合在一起。其全热交换过程，是在通过风机引导排气与进气两股气流分别通过该热回收芯体1进行室内外空气交换时，两股气流由于温差而在交互通过时作热量传递，而同时由于该隔板2对水气具有渗透性，因此也达到湿气质传效果，从而在排气与进气两股气流之间作温度与湿度的交换，实现节能与排污效果。The working principle of the heat recovery core is shown in Figure 1. The core 1 is a moisture-permeable but heat-impermeable wet heat exchangeable paper material, such as fiber paper base material, etc., as the separator 2, and the separator 2 is provided with A plurality of wave-shaped plates 4 of the airflow inlet 3, and these wave-shaped plates 4 are staggered and cross-arranged on the indoor side I and the outdoor side II, thereby forming an unconnected indoor exhaust passage EE and outdoor intake passage in the core 1 FF, to ensure that the two streams will not mix together. The whole heat exchange process is that when the two airflows of the exhaust and the intake air are guided by the fan to perform indoor and outdoor air exchange through the heat recovery core 1, the two airflows transfer heat when they pass through due to the temperature difference, and at the same time Since the separator 2 is permeable to water vapor, it also achieves the effect of moisture mass transfer, so that the temperature and humidity are exchanged between the two air streams of the exhaust gas and the intake air, and the energy saving and sewage effects are achieved.
