Description

A ductless two-way fresh air system

technical field

The utility model relates to a ventilation system, in particular to a ductless two-way fresh air system.

Background technique

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.

While improving the indoor air quality, mechanical ventilation also directly and instantaneously affects the indoor thermal and humid environment. The amount of ventilation and the ventilation mode are related to whether the building is energy-efficient. According to research, in accordance with indoor sanitation requirements, timely and appropriate ventilation during heating and air conditioning, instead of opening windows uncontrollably, can achieve effective building energy conservation under the premise of ensuring indoor air quality. Therefore, there is an urgent need for a ventilation system suitable for modern houses to meet the current needs.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the ductless two-way fresh air system described in the utility model is installed on the building exterior wall 11, and the building exterior wall 11 is provided with at least one set of ventilation openings (including: ventilation openings) 13. Air vent 14). The ventilation system includes at least one group of fans (including fans 3 and 4 as shown in Figure 2) and a time controller for controlling the opening/closing of the fans when a preset time is reached (including Time controller 9 and time controller 10 in), each ventilator (comprising ventilator 3, ventilator 4 in Fig. 2) is arranged on each vent (comprising vent 13, vent 14 in Fig. 2 ), and is controlled by the corresponding time controller (including time controller 9 and time controller 10) to start exhausting outside or stop running. Since the ventilation system is installed without ducts, it can save the ceiling space of the building and is convenient for installation and maintenance. Due to the negative pressure exhaust system, the room has a good air flow organization, which can reduce the stagnation of turbid wind in the whole house.

Still as shown in Figure 1, the fan and the corresponding time controller can be pre-connected and assembled into a ductless two-way fresh air device (that is, the ductless two-way fresh air device 1 and the ductless two-way fresh air device 2 in Figure 1 ), this ductless two-way fresh air device can be quickly applied to the site to improve installation efficiency.

As shown in Figure 2, in practical applications, a filtering device (i.e. filtering device 5, filter device 6), the ventilator is arranged on the inside of the filter device, that is, the ventilator 3 is arranged on the inside of the filter device 5, that is, on the side close to the room; the ventilator 4 is arranged on the inside of the filter device 6 The inner side, that is, the side close to the interior. The filter device 6 can be specifically a filter screen, which has low resistance and high efficiency, and is controlled by a two-way one-way valve to effectively remove PM2.5 in the atmospheric environment and provide protection for the health of indoor personnel.

Further, a ventilation grille can also be provided on the side of the ventilation opening (ie the ventilation opening 13 and the ventilation opening 14 in FIG. 2 ) facing the room, and the ventilation fan is located between the ventilation grille and the filter device. That is, as shown in Figure 2, the ventilation grill 7 is arranged on the indoor side of the vent 13, and the ventilator 3 is located between the ventilation grill 7 and the filtering device 5; the ventilation grill 8 is arranged on the The ventilation opening 14 faces the indoor side, and the ventilator 4 is located between the ventilation grille 8 and the filtering device 6 .

The application process of the ductless two-way fresh air system described in the utility model is as follows:

As shown in Figure 3, according to the setting time of the time controller 9, when the bedroom needs to be ventilated, the time controller 9 arranged in the bedroom provides a start signal to start the ventilator 3, and the dirty air in the bedroom is discharged outdoors; Simultaneously, due to the exhaust effect of ventilator 3, negative pressure is formed indoors, and outdoor fresh air enters the living room through the ductless two-way fresh air device 2, forming the ventilation of the whole house. When the indoor ventilation volume and ventilation time requirements are met, the time controller 9 gives a shutdown signal, and the ventilator 3 stops running.

As shown in Figure 4, according to the setting time of the time controller 10, when the living room needs to be ventilated, the time controller 10 arranged in the living room gives a start signal to start the ventilator 4, and the dirty air in the living room is exhausted. At the same time, due to the exhaust effect of the ventilator 4, negative pressure is formed indoors, and outdoor fresh air enters the bedroom through the ductless two-way fresh air device 1, forming the ventilation of the whole house. After the indoor ventilation volume and ventilation time requirements are satisfied, the time controller 10 gives a shutdown signal, and the ventilator 4 stops running.

In the above embodiment, the time controller can be a timer, which can realize the setting and control of the preset time in different periods and regions, so as to meet the ventilation requirements of different functional rooms in different periods.
