Embodiment 1

[0056] A fresh air system, see figure 1 and figure 2 , including a fresh air duct 10 , an exhaust duct 20 , a first duct 30 , and a control module 60 . Wherein, the fresh air duct 10 is used to send outdoor air into the room. Specifically, along the direction in which the air flow flows from outdoor to indoor in the fresh air duct 10, a first air stop valve 12, a fresh air blower, and a first air stop valve 12 are sequentially arranged on the fresh air duct 10. 15. The exhaust duct 20 is used to discharge indoor air to the outside, and an exhaust fan 23 is arranged on the exhaust duct 20 . One end of the first pipeline 30 is arranged between the first air stop valve 12 and the fresh air blower 15, the other end of the first pipeline 30 communicates with the air inlet side of the exhaust fan 23, and the first pipeline 30 is provided with a second wind stop Valve 31. The control module 60 is electrically connected to the first air stop valve 12 , the fresh air fan 15 , the ...

Embodiment 2

[0088] A fresh air system, see Figure 8 , Figure 9 , Figure 10 ,in, Figure 9 and Figure 10 The arrows in are pointing to the airflow direction. The difference between the fresh air system described in this embodiment and the fresh air system described in Embodiment 1 is that it further includes a body 80 , and the fresh air system described in Embodiment 1 is integrated into a body 80 .

[0089] Specifically, the heat exchanger 70 is disposed in the middle of the body 80 . The air inlet and the air outlet of the fresh air duct 10 are respectively arranged on the left side and the right side of the body 80; according to the direction in which the outdoor air flows into the room, the above-mentioned raindrop detection module 11 and the first wind stop are installed on the fresh air duct 10 in sequence. Valve 12, primary filter, first sensor module 14, high-efficiency filter, activated carbon filter, heat exchanger 70, fresh air blower 15. The air inlet and the air out...

Embodiment 3

[0094] A fresh air system, which differs from the fresh air system described in Embodiment 1 or Embodiment 2 in that it also includes a wall-type air outlet device (not shown in the figure), and the wall-type air outlet device can be installed on a window or on a On the wall within 0.5 meters from the window frame. Wherein, the wall-type air outlet device is a wall-type air inlet device sold on the market, and its specific structure will not be discussed here. The window can be a window that can be ventilated, such as a sliding window, a window, a shutter, etc., and the window can also be a window that cannot be ventilated, such as a curtain wall. Through this design, on the one hand, the effect of air supply or exhaust can be improved; on the other hand, the installation of the air outlet needs to open holes on the wall. Considering that there are generally no load-bearing walls near the windows, openings near the windows Holes and installation of air vents will not cause to...

Abstract

The invention relates to a ventilation system and a control method thereof. The ventilation system comprises a ventilation pipeline, an air exhaust pipeline, a first pipeline and a second pipeline, wherein the ventilation pipeline is used for sending outdoor air into a room and internally provided with a ventilation fan and a first check valve; the air exhaust pipeline is used for exhausting indoor air to the outside, and an air exhaust fan is arranged in the air exhaust pipeline; one end of the first pipeline is connected to the air intake side of the exhaust fan; and one end of the second pipeline is connected with the other end of the first pipeline, the other end of the second pipeline is used for being connected into a room, and a fourth check valve is arranged in the second pipeline.When the indoor air meets any one of the following conditions, the first check valve and the ventilation fan are closed, and the exhaust fan is started: (1) the PM2.5 of the indoor air is greater than or equal to 300 [mu]g/m<3>; (2) the carbon dioxide mass change of the indoor air is greater than or equal to 1500ppm; (3) the temperature of indoor air is smaller than or equal to minus 10 DEG C andlarger than or equal to minus 40 DEG C; and (4) the humidity of the indoor air is greater than or equal to 65%. Through the design, pipeline condensation can be effectively avoided when fresh air isprovided.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fresh air system and a control method for the fresh air system. Background technique [0002] The fresh air system is an effective air purification device, which can introduce fresh outdoor air into the room after filtering, heating and other processes, and can also discharge indoor dirty air outside. [0003] After many years of research and development by the inventor, the inventor found that in the process of using the fresh air system in northern China in winter, when it is necessary to send fresh air into the room, due to the low outdoor temperature, the pipes that send the outdoor fresh air into the room are prone to knots. Expose the problem. In order to solve this problem, the current fresh air system generally relies on PTC heaters to solve it. However, this solution can only work when the external temperature is a certain temperature, and if the external temperature ...
