Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0043] like Figure 1-3 , Figure 5-7 The two-way flow all-heating fresh air device shown includes a box body 100, the box body preferably has a sheet metal structure, and the side wall of the box body is provided with an outdoor air inlet connection 101, an indoor air outlet connection 102, an indoor return air connection 103, and an outdoor exhaust air connection. Take over the pipe 104, and the box is equipped with an outdoor air supply fan 200, an indoor air supply fan 300, and a two-way flow total heat exchanger 400. The two-way flow total heat exchanger has an air inlet channel and an air outlet channel that are isolated from each other and capable of heat exchange , the air inlet channel and the air outlet channel are composed of several gaps;

[0044] The inner cavity of the box body 100 is divided into an outdoor side cavity 105 and an ind...

Abstract

The invention discloses a bidirectional-flow total-heat fresh air device and belongs to fresh air devices. An existing fresh air device is large in product thickness and internal air channel resistance. According to the bidirectional-flow total-heat fresh air device, centrifugal draught fans used as an indoor air supply draught fan and an outdoor air supply draught fan are transversely arranged, namely the axial direction of a centrifugal wind wheel of each centrifugal draught fan is identical with that of the thickness of a box body, so that the product thickness is reduced, and the product thickness can reach 200-220 mm. Besides, an outdoor side cavity and an indoor side cavity of the box body are each partitioned into an upper layer and a lower layer which are used for intake and exhaust correspondingly, so that the internal air channel resistance is reduced; in this way, the product thickness is reduced, the same ventilation efficiency is guaranteed, and the power of the draught fans is not increased.

Description

technical field [0001] The invention belongs to a fresh air device, in particular to a two-way flow all-heat fresh air device. Background technique [0002] The density of modern buildings is getting higher and higher, and the airtightness of housing is getting better and better. When the outdoors are cold in winter and the outdoors are hot in summer, the doors and windows are generally sealed, which leads to an increase in the indoor carbon dioxide content and makes people's living comfort more comfortable. decline. In order to improve living comfort, indoor ventilation is required. This ventilation will discharge indoor energy to the outside, resulting in energy loss; it will also transport polluted air indoors when the outdoor air quality is not good. Therefore, heat recovery and outdoor PM2.5 filtration are carried out while ventilating. This requires a whole house heat exchanger to achieve. [0003] But in the bathroom, because there is no heating in the south, the t...
