Humidity control method of fresh air system

Abstract

The invention belongs to the technical field of fresh air, and particularly provides a humidity control method of a fresh air system. The humidity control method aims to solve the problem that an existing fresh air system cannot well adjust the humidity of fresh air, and consequently the comfort degree of the fresh air is poor. Therefore, the fresh air system comprises a shell and a humidity adjusting component rotatably arranged in the shell. The humidity control method can control the rotating position of the humidity adjusting component according to the fresh air supply requirement, so thatthe fresh air system can selectively supply fresh air according to the use requirement of a user; the opening and closing states of an indoor heating component and an outdoor heating component are controlled through the rotating position of the humidity adjusting component and the indoor relative humidity, so that the fresh air system can correspondingly start a humidifying function or a dehumidifying function according to the humidity adjusting requirement, and the humidity of the fresh air is effectively controlled; and therefore, the indoor relative humidity is controlled to be always keptin a proper range to the greatest extent, so that the user experience is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fresh air, and specifically provides a humidity control method for a fresh air system. Background technique [0002] With the continuous development of fresh air technology, users have higher and higher requirements for the quality of fresh air supplied by the fresh air system. Take the humidity of the fresh air as an example. When the fresh air system is used in some areas with excessive humidity or in the rainy season with heavy humidity, the introduction of a large amount of humid air will inevitably cause discomfort to users; or, when the fresh air system is used in some areas with excessive humidity. When used in a small area or in the dry autumn and winter seasons, the introduction of a large amount of dry air will inevitably cause discomfort to the user. Under these circumstances, the humidity adjustment capability of the fresh air system is particularly important. Only when the fresh air system c...

Problems solved by technology

[0005]In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing fresh air system cannot adjust the humidity of the fresh air well and lead to poor comfort of the fresh air, this The invention provides a method for controlling the humidity of a fresh air system. The fresh air system includes a housing and a humidity adjustment member rotatably arranged in the housing. The housing is formed with first fresh air passages, The second fresh air channel, the third fresh air channel and the fourth fresh air channel, the first fresh air channel communicates with the indoor air outlet and the first fresh air channel is provided with an indoor fresh air unit, the second fresh air channel is connected to the indoor return The air outlets are connected, and the second fresh air channel is provided with an indoor heating component, the third fresh air channel is connected with the outdoor air outlet, and the third fresh air channel is provided with an outdoor fresh air unit, and the fourth fresh air channel is connected to the outdoor air outlet. The outdoor air inlets are connected, and an outdoor heating component is arranged in the fourth fresh air passage, and the humidity regulating component includes a first humidity regulating core and a second humidity regulating core independently arranged, and the first humidity regulating core The body and the second humidity adjustment core are set to be able to absorb moisture under non-high-temperature airflow to achieve dehumidification and to release moisture under high-temperature airflow to achieve humidification, and the humidity adjustment member is configured to rotate to In the first position, the first fresh air passage communicates with the second fresh air passage through one of the first humidity adjustment core and the second humidity adjustment core, and the third fresh air passage communicates with the second fresh air passage. The fourth fresh air channel communicates with the other one of the first humidity-regulating core and the second humidity-regulating core, and when the humidity-regulating member rotates to the second position, the first fresh air channel and the second humidity-regulating core communicate with each other. The fourth fresh air channel communicates with one of the first humidity-regulating core and the second humidity-regulating core, and the second fresh air channel and the third fresh air channel pass through the first humidity-regulating core body and the other one of the second humidity adjustment core; the humidity control method of the present invention includes: obtaining fresh air supply demand; controlling the rotation position of the humidity adjustment member according to the obtained result of fresh air supply demand; obtaining indoor relative humidity ; Control the opening and closing states of the indoor heating member and the outdoor heating member according to the rotational position of the humidity adjustment member and the indoor relative humidity
