[0003]
However, due to the limitation of the hollow fiber membrane process, the diameter can only be 2-4mm, the air flows in the 2-4mm circular tube, the resistance loss is very large, and the final air volume is very small
[0004] In addition, fresh air fans in the prior art are usually divided into a filter box and a casing. The filter box filters the air, and a total heat exchanger is installed in the casing. The filtered air and return air pass through the total heat exchange in the casing. Heat exchange with the device, resulting in a larger overall volume

The invention discloses a modularized integrated ventilator. A hollow fiber membrane filtering device, a total heat exchanger, a fresh air outlet flow channel, a return air inlet flow channel and a return air outlet flow channel are arranged in a machine shell, the hollow fiber membrane filtering device is connected with an air inlet and provided with an air filtering outlet, and the air filtering outlet is connected with the total heat exchanger; one end of the fresh air outlet flow channel is connected with the total heat exchanger, the other end of the fresh air outlet flow channel is connected with the fresh air outlet, one end of the return air inlet flow channel is connected with the return air inlet, the other end of the return air inlet flow channel is connected with the total heat exchanger, one end of the return air outlet flow channel is connected with the total heat exchanger, the other end of the return air outlet flow channel is connected with the return air outlet, the fresh air outlet flow channel is provided with the ventilator, and the return air outlet flow channel is provided with a return air fan. According to the ventilator, by adopting the technical scheme, the hollow fiber membrane filtering device, a return air structure and the total heat exchanger are arranged in the machine shell together, a box body is prevented from being independently arranged, the structure is more compact, and the size is reduced.
Description
technical field [0001] The invention relates to the field of environmental protection, in particular to fresh air fans. Background technique [0002] In recent years, people have paid more and more attention to indoor air quality. Fresh air fans using hollow fiber membrane filter elements can filter outdoor dirty air through PTFE hollow fiber membranes. Due to the use of PTFE hollow fiber membrane as the filter material, the filter element has no consumables and does not need to be replaced. It can be cleaned and used repeatedly. The dust holding capacity is 30-50 times that of the traditional filter, the service life is long, and the high removal rate can be maintained for a long time. [0003] However, due to the limitation of the hollow fiber membrane process, the diameter can only be 2-4mm, and the air flows in the 2-4mm circular tube, the resistance loss is very large, and the final air volume is very small. [0004] In addition, fresh air fans in the prior art are usu...
