The explosion of fresh air system in homes is a trend of relatively large air pollution. It is worth the industrial production link in Europe in the last century, and the fresh air system has already become the standard configuration for the construction of many houses in China. Now in China, a series of indoor ecological environment problems under the influence of haze weather have forced everyone to focus on this natural ventilation and purification equipment that can reduce the air quality in the room, Household fresh air fans are also gradually becoming mature and standardized. So how to choose the type of household fresh air fan?
The household fresh air fan is a kind of blood circulation system software that can operate continuously for 24 hours, introduce fresh outdoor air without opening the window, and discharge the turbid air containing carcinogens such as formaldehyde, benzene and ammonia in the room according to the physical principle, so that the outdoor and indoor air can be exchanged with each other according to sufficient conditions, so as to ensure that there is sufficient fresh air in the room.
If the new house has not been decorated, and the height and structure of the household fresh air fan are approved, install the total heat exchanger fresh air system as far as possible, with stable ventilation volume and small changes in temperature and humidity records in the room; If it is used with air conditioner, it can save cost for long-term operation. If the house has been decorated for a long time, it is necessary to install a wall mounted or home ownership fresh air system without affecting the overall situation. If the economic development situation does not allow the investment of the project to be too large, the wall mounted fresh air system can also be selected, which can be installed in the bedroom first. In the final analysis, the bedroom is a closed part where people stay for a long time, and fresh air should be used.
