Air total heat exchanger for changing runner to improve efficiency

Abstract

The invention relates to a novel air total heat exchanger which comprises a fresh air runner, a fresh air fan, an exhaust air runner, an exhaust fan and a total heat exchange core body. Fresh air and exhaust air are subjected to total heat exchange through a heat-moisture exchange membrane in the total heat exchange core body; inlets and outlets of the fresh air and the exhaust air of the total heat exchanger are laterally arranged relative to the total heat exchange core body; the fresh air inlet and the exhaust air outlet are arranged at the same end faces of different sides on the same horizontal plane; the fresh air outlet and the exhaust air inlet are arranged at the same end faces of the different sides on the same horizontal plane; the fresh air inlet and the exhaust air outlet are respectively arranged at the upper and lower layers (or lower and upper layers) at the same side of the total heat exchange core body; the fresh air outlet and the exhaust air inlet are respectively arranged at the lower and upper layers (or upper and lower layers) at the other same side of the total heat exchange core body, and diversion partition plates are arranged inside the fresh air runner and the exhaust air runner. Therefore, the air can be uniformly arranged on the total heat exchange core body; the total heat exchange efficiency is improved, and the air resistance is reduced.

Description

technical field [0001] The invention relates to a device for exchanging total heat (including sensible heat and latent heat) of indoor and outdoor air. More particularly, the present invention relates to an air total heat exchanger with an improved channel structure, which can improve total heat exchange efficiency and reduce resistance. Background technique [0002] In order to ensure that the indoor air is fresh, sufficient fresh air volume must be ensured in the building air conditioner. Especially due to the rapid development of chemical industry and material industry, a large amount of artificial synthetic materials have appeared as building materials and decoration materials, and these materials can release harmful gases such as formaldehyde, benzene, toluene, ethanol, chloroform, etc. The deterioration of the indoor air environment causes people in the building to feel uncomfortable, dizzy, irritated, nauseous and even sick, which has triggered the following three di...

Problems solved by technology

Adopting this air intake method improves the problem of uneven distribution of exhaust air and fresh air after entering the core of the total heat exchanger to a certain extent. However, there are still local air distribution problems that are too concentrated or thin along the direction of the core. Phenomenon

[0007] At the same time, when using the total heat exchangers described in Patent Document 1 and Patent Document 2, due to the design of multiple corners in the channel design, it is easy to generate eddy currents locally when the air passes through the channels, which affects the thermal efficiency of the total heat exchanger. Exchange efficiency, while increasing the pressure loss of the entire heat exchange process
