Problems solved by technology

[0003] However, the existing fresh air fans have the following disadvantages: (1) The heat convection structure design of the heat exchanger is unreasonable, the heat exchange is insufficient, the heat exchange time is short, the waste heat is not fully utilized, and the exchange efficiency is low, resulting in a waste of energy
(2) The internal structure design of the new fan is unreasonable, with large volume, large wind resistance and poor exhaust

Embodiment Construction

[0017] The invention will be described in detail below with reference to the drawings, but the invention is not limited to the following examples.

[0018] Such as figure 1 , figure 2 As shown, a fresh heat recovery fan includes a casing 5, a primary filter 1, a high efficiency filter 2, a plate heat exchanger 3, a blower 4, and an exhaust fan 6. The casing 5 is made of non-metallic materials such as metal or plastic, artificial board, etc., and the primary filter 1, the high efficiency filter 2, the plate heat exchanger 3, and the blower 4 are installed in the casing 5 in parallel in turn. After the fresh air enters from the fresh air inlet 9 of the casing 5, it passes through the primary filter 1, the high-efficiency filter 2, the plate heat exchanger 3, and the blower 4 arranged in parallel successively, and then sends out from the fresh air outlet 7. The outlet of the air blower 4 is also provided with an air regulating frame 11, and the air regulating frame 11 is provi...

Abstract

The invention relates to a heat recovery fresh air machine. The machine comprises a machine shell, a primary filter, a high-efficiency filter, a plate type heat exchanger, an air supply machine and an exhaust fan. Counter-flow heat exchange enabling fresh air and exhausted air to be vertically staggered is adopted in the fresh air machine. The fresh air is conveyed outwards via a fresh air outlet after sequentially passing through the primary filter, the high-efficiency filter, the plate type heat exchanger and the air supply machine which are arrayed in parallel. The exhausted air is exhausted via an exhausted air outlet after sequentially passing through the plate type heat exchanger and the exhaust fan. The fresh air machine has the advantages that the structure is compact; the waste heat is fully used; the design of an air channel is ingenious; the cost is low; and the installation is convenient.

Description

technical field [0001] The invention relates to an air treatment device, in particular to a heat recovery fresh fan. Background technique [0002] The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is full of fresh and clean air all the time. The fresh air fan uses the fresh air convection technology to achieve convection of the indoor air through independent air supply and induction, thereby maximizing the indoor air replacement. [0003] However, the existing fresh air fans have the following disadvantages: (1) The heat convection structure design of the heat exchanger is unreasonable, the heat exchange is insufficient, the heat exchange time is short, the waste heat is not fully utilized, and the exchange efficiency is ...
