How to solve the problem that the office building can't be ventilated normally?

1, window ventilation: it will bring a lot of dust and sound; And there are hidden dangers such as theft prevention and rain protection; And it can't be ventilated continuously (but many office buildings are curtain wall structures with fewer windows);

2. Turn on the ventilator for ventilation: the sound will be louder; Can't keep ventilation; There is no fresh air inlet, which affects the ventilation effect (many ventilation fans only discharge to the ceiling, but do not really achieve ventilation)

3. Negative ion generator or air purifier for ventilation: air can only be repeatedly treated and filtered, and it cannot really replace fresh air (there is no fresh air supplement).

4. Air conditioning with some fresh air or home central air conditioning for ventilation: only a little outdoor air can be added, and the effect is not good; On the contrary, the problem of ventilation cannot be completely solved.

5. Mechanical ventilation mode: Mechanical ventilation mode refers to fresh air ventilation system.

According to the indoor area and ventilation demand, it is a better ventilation method to realize it through ventilation equipment. It is also the mainstream ventilation mode at present. The fresh air ventilation system has built-in high-efficiency heat exchanger, which can effectively avoid the loss of indoor cold air during ventilation, greatly save energy during ventilation, and ensure that the power consumption of air conditioning in summer and heating equipment in winter will not increase.
