Embodiment 1

[0033] For the humidification of home bedroom, the ground area is 15 square meters.

[0034] Such as figure 1 As shown, the humidifying device based on the hydrophobic polymer film of the present invention includes a liquid humidifier 3, an air heater 2 and a water storage tank 6, the liquid humidifier 3 is connected with the air heater 2 by an air inlet 7, and is connected by a drain The air port 8 communicates with the indoor air through the indoor fan 4, and the liquid humidifier 3 is also communicated with the water storage tank 6 through the liquid inlet 9 through the solution pump 5, and the liquid inlet 9 and the liquid discharge port 10 are connected with the water storage tank 6. Communication; the air heater 2 communicates with the outdoor air through the outdoor fan 1 . Such as image 3 , Figure 4 As shown, the liquid humidifier 3 includes a top cover 25, a humidification chamber 26, a hydrophobic microporous membrane 27, and a housing 28. The top cover is provi...

Embodiment 2

[0036] The hydrophobic microporous membrane 27 is made of polyethersulfone through a dry-wet phase inversion method, with a pore size of 0.3 μm. other same

[0037] Example 1.

Embodiment 3

[0039] The hydrophobic microporous membrane 27 is made of polyacrylonitrile through dry-wet phase inversion method, and the pore size is 0.3 μm. Others are with embodiment 1.

Abstract

A non-contact humidification or dehumidification system of hydrophobic polymer film consists of liquid humidifier or dehumidifier which connects to air indoor and outdoor separately and includes hydrophobic polymer film of 0.15 - 5.0 micro m diameter hole and said film is made of PVDF , PTFE , PVC , PAN and PES under dry - wet phase conversion method . It features using said film to isolate humidification or dehumidification chamber to be two spaces with closed top and bottom for avoiding direct contact of humidifying or dehumidifying agent to the air.

Description

technical field [0001] The invention relates to a humidification / dehumidification device, in particular to a non-contact air humidification / dehumidification device, especially a humidification / dehumidification device based on a hydrophobic polymer film. Background technique [0002] In addition to temperature, humidity is another important indicator related to the comfort of the room. In summer, people need to dehumidify the indoor air; in winter, people need to humidify the indoor air. An environment with too high humidity or too low humidity will increase the discomfort of the human body, and will also cause a large number of certain viruses and bacteria to multiply inside the building. In addition, in the industry, whether many production processes can be carried out correctly depends largely on the humidity parameters, and many production processes have strict requirements on humidity. [0003] At present, the most widely used humidificatio...
