Abstract

The invention discloses a non-pipe type bidirectional fresh air system which is installed on the external wall of a building; at least one group of ventilating openings are arranged on the external wall of the building; the non-pipe type bidirectional fresh air system further comprises at least one group of ventilators and time controllers for controlling the starting / shutdown of the ventilators within a preset time; each ventilator is arranged at each ventilating opening and the starting / shutdown of the ventilator is controlled by the corresponding time controller. In the non-pipe type bidirectional fresh air system, the ventilators and the corresponding time controllers are arranged in pairs; the ventilators are controlled orderly by means of the time controllers, so that the timely and moderate ventilation is realized, the indoor air quality is improved and the ventilating energy consumption of the building is reduced effectively.

Description

technical field

[0001] The invention relates to a ventilation system, in particular to a ductless two-way fresh air system. Background technique

[0002] Housing is the place where people live and live every day, and fresh and clean air is the basis for people's health and quality of life. At present, the ventilation method used in residential buildings is mainly natural ventilation. With the continuous improvement of the airtightness of building exterior windows, natural infiltration ventilation can no longer meet the requirements of indoor air quality; if windows are used for ventilation, not only the ventilation volume and airflow resistance are difficult to control, but also noise pollution will be caused. Therefore, mechanical ventilation, or a combination of natural and mechanical ventilation, has become the main means of solving residential indoor air quality.

[0003] While improving the indoor air quality, mechanical ventilation also directly and instantaneously a...
