A self-conducting disc-type series total heat exchange core

Abstract

The invention relates to an indoor heat exchange and ventilation device, in particular to a self-conduction disc type series full heat exchange core. The self-conduction disc type series full heat exchange core comprises an upper disc, a lower disc, a moisture permeable thin film, a rubber pressing strip, a first connecting pipe and a second connecting pipe; the upper disc body is an aluminum alloy tubular body with a built-in hollow and a rectangular section; and the upper gap leading-out part is the rectangular body with the built-in hollow. The full-heat-exchange and whole-course countercurrent in the ventilation process is realized, the humidity and temperature exchange is ensured, more energy is saved, a smaller size can be used, the problem of space occupation is solved, and high-efficiency humidity exchange is realized by using the combination of the disc bodies.

[0002] In order to ensure the indoor air quality, it is often necessary to install a ventilation device to discharge indoor pollutants and dirty air to the outside, and at the same time supply fresh outdoor air to the room to meet the needs of human health standards. However, the indoor and outdoor air is directly discharged Replacement will bring a lot of energy loss. In order to solve indoor air pollution and consider energy-saving issues at the same time, it is increasingly important to apply ventilation devices with dual exchange of temperature and humidity to air-conditioning systems;

[0003] In the prior art, using the rotating full heat exchange runner as the medium can make the two airflows of the intake air and the exhaust air realize the double total heat exchange of temperature and humidity, which is one of the means. Air flow, due to the steering effect, makes the flow field very chaotic, resulting in uneven distribution of the air volume entering the runner. The above-mentioned uneven air volume distribution and chaotic phenomenon of the flow field make it difficult to make the exhaust and intake air flows in a reverse and countercurrent manner. Flowing through the runner is very detrimental to the overall exchange efficiency. Its heat exchange efficiency is completely determined by the material with strong hygroscopicity and strong permeability of the runner. However, this material is better for humidity exchange and often improves heat transfer. unable to balance;
