Problems solved by technology

However, when the wind speed on the air inlet side is too high, the air flow will be unevenly distributed on the windward side of the heat exchange core, which will affect the heat exchange efficiency of the total heat exchanger.

Embodiment 1

[0077] Using the present invention figure 1 The total heat exchanger shown measures its exchange efficiency. The measurement conditions are: indoor exhaust air dry bulb temperature 22.0±0.5°C, moisture content 10.5±0.5 g·kg -1 , outdoor fresh air dry bulb temperature 30.0±0.5℃, moisture content 15.8±0.5 g·kg -1 , using 7 splitters, the radian of the splitter is 105°, the tangent direction of the air inlet end of the splitter is parallel to the air inlet direction, and the tangent direction of the air outlet end is perpendicular to the windward surface of the core.

Embodiment 2

[0081] Using the present invention figure 1 The total heat exchanger shown measures its exchange efficiency. The measurement conditions are: the indoor exhaust air dry bulb temperature is 21.5±0.5°C, and the moisture content is 9.5±0.5 g·kg -1 , outdoor fresh air dry bulb temperature 13.5±0.5℃, moisture content 5.8±0.5 g·kg -1 , using 7 splitters, the radian of the splitter is 105°, the tangent direction of the air inlet end of the splitter is parallel to the air inlet direction, and the tangent direction of the air outlet end is perpendicular to the windward surface of the core.

Abstract

The invention discloses a total heat exchanger which comprises a shell, fresh air flow channels, exhaust flow channels, heat exchange cores and at least one distributing partition plate. The fresh air flow channels are used for supplying outdoor fresh air to an indoor environment; the exhaust flow channels are used for exhausting indoor air to an outdoor environment; the heat exchange cores are arranged at crossed positions of the fresh air flow channels and the exhaust flow channels in a crossed manner; the distributing partition plates are respectively arranged in an air-inlet-side channel of the fresh air flow channels and an air-inlet-side channel of the exhaust flow channels. The total heat exchanger has the advantages that air in the heat exchange cores can be uniformly distributed, eddy currents can be prevented, and accordingly the heat exchange efficiency of the total heat exchanger can be improved.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and in particular relates to a device for exchanging total heat (including sensible heat and latent heat) of indoor and outdoor air, that is, a total heat exchanger. 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 materials industry, a large amount of artificial synthetic materials have appeared as building materials and decoration materials, and these materials will release harmful gases such as formaldehyde, benzene, toluene, ethanol, chloroform, etc. [0003] The deterioration of the indoor air environment will cause people in the building to feel uncomfortable, such as dizziness, irritability, nausea, etc., and even produce diseases. For example, it may cause the following three diseases: Sick Building Syndrome (SBS), relate...
