Embodiment 1

[0044] Such as Figure 1 to Figure 10 As shown, the air heat and moisture recovery core of the hydrophilic film reverse flow air duct, referred to as the heat and moisture recovery core 1, as shown in figure 1 , figure 2 As shown, it includes a mesh plate, a heat transfer film 103, six fixing rods 104 and a cover plate 105;

[0045] Such as Figure 3 to Figure 7 As shown, the screen is rectangular, and the screen is divided into an upper layer 10, a middle body layer 11 and a lower layer 12 in the upper and lower directions. The middle body layer 11 includes 8 channel isolation strips 106, and each adjacent 2 channel isolation bars 106 to form an air flow channel; the upper layer 10 and the lower layer 12 are used for installing the heat transfer film 103 and the positioning of the mesh plate, and the mesh plate is provided with 6 fixed rod perforations 107, which are used as the fixed rod 104 for positioning during assembly; The board includes several pieces of fresh air...

Embodiment 2

[0067] The hydrophilic membrane is a heterogeneous hydrophilic membrane;

[0068] The heterogeneous hydrophilic membrane is immersed in a hydrophilic membrane on a composite material membrane using a heterogeneous membrane substrate. The heterogeneous membrane is a patented heat and moisture transfer membrane (see the publication number: CN202463073U for details, the patent number: 2011204094071, and the invention name is : a kind of out-of-phase film and out-of-phase film core);

[0069] Due to the significant difference in the thermal conductivity of the substrate, the function of heat and moisture transfer has its own characteristics; the substrate of the heterogeneous film is a non-metallic material, the thermal conductivity is only 0.04w / mk, and the film thickness is calculated as 0.12mm, and its heat transfer is 333w / k ;The heat release coefficient of the air in the air duct is about 2200w / m 3 k, the heat release of air in the air duct is based on the air flow rate of 1...

Abstract

The invention discloses a hydrophilic membrane reverse flow air flue air heat and humidity recovery machine core, and belongs to the technical field of general heat exchange parts. The hydrophilic membrane reverse flow air flue air heat and humidity recovery machine core comprises a mesh plate, a heat transfer membrane, a plurality of fixing rods and a cover plate, the mesh plate is rectangular, the mesh plate is divided into an upper layer, a middle main body layer and a lower layer, the middle main body layer comprises a plurality of channel isolation strips, an air flow channel is formed between every two adjacent channel isolation strips, the upper layer and the lower layer are used for installing the heat transfer membrane and the mesh plate for positioning, the heat transfer membraneis separated from the mesh plate, and the heat transfer membrane is a hydrophilic membrane. The hydrophilic membrane reverse flow air flue air heat and humidity recovery machine core has the beneficial effects that the heat recovery is full-reverse recovery, the recovery efficiency is high, and the volume is small.

Description

technical field [0001] The invention relates to an air duct air heat recovery core, in particular to a hydrophilic membrane reverse flow air duct air heat and humidity recovery core, and belongs to the technical field of general heat exchange components. Background technique [0002] With the development of the economy and the improvement of people's quality of life, people pay more and more attention to indoor air quality (IAQ). The extensive discussion caused by PM2.5 has brought huge business opportunities to household fresh air fans. Fresh air fans can meet the requirements of indoor air purification. Haze, heat recovery, moisture recovery, indoor purification and other functional treatment. The core technology of household fresh air fans is the air duct air heat recovery core. The energy and moisture recovery efficiency of the air duct air heat recovery core, as well as the installation volume, are directly related to the use effect of household fresh air fans. . In t...
