Description

【Technical field】 [0001] The present invention relates to a ventilation device, in particular to a ventilation device for improving indoor and outdoor air quality and having double exchange of temperature and humidity. 【Background technique】 [0002] In actual daily life, in order to ensure the indoor air quality, it is often necessary to install ventilation devices such as air conditioners, especially in places where people are relatively concentrated, so that indoor pollutants and dirty air (exhaust) can be discharged outdoors in a timely manner. At the same time, the outdoor fresh air (air intake) is supplemented indoors to meet the needs of human health standards. [0003] However, directly replacing the indoor and outdoor air will cause a large amount of energy loss. For example, in summer, when a large amount of hot air with a high outdoor temperature is used to replace the cold air in the room that has been air-conditioned, a large energy loss will occur; On the othe...

Problems solved by technology

[0007] (1) The flow field of the air entering the total heat exchange runner is chaotic and the flow distribution is uneven

As we all know, the maximum exchange efficiency can be achieved when the two airflows of the intake air and the exhaust air evenly flow through the runner in counter flow mode to exchange sensible heat and latent heat. The wind direction of the tiny channel in the runner is at a vertical angle, and the end of the flow path of the main airflow blown in is a facing end plate of the casing, which is subjected to the interaction between the secondary airflow directly impacting the end plate and the incoming main airflow and The steering effect makes the flow field in between very chaotic, resulting in the uneven distribution of the air volume entering the runner. The above-mentioned uneven air volume distribution and the chaotic phenomenon of the flow field make it difficult for the exhaust and intake air to flow through in a countercurrent manner. The runner is very detrimental to the overall exchange efficiency

[0008] (2) Heat exchange efficiency needs to be improved

Since the exchange of sensible heat and latent heat is achieved by passing the two airflows through the runner with a honeycomb structure during the intake and exhaust, the heat exchange efficiency is completely determined by the runner, but the runner is made of a material with strong hygroscopicity and strong permeability. Material is the main appeal, and the improvement of heat transfer effect is often unable to take into account. There is still a lot of room for improvement in the efficiency of sensible heat exchange.
