Precautions for purchase:

1, what kind of fresh air system do you choose?

If the new house has not been renovated and the height and structure permit, it is recommended to install a total heat exchange fresh air system with stable ventilation and little change in indoor temperature and humidity; If used in conjunction with air conditioning, long-term operation will save money.

If the house has been renovated, only split fresh air system can be installed. If the economic conditions do not allow too much one-time investment, you can also consider the split fresh air system, which can be installed in the bedroom first. The bedroom is the most closed place. People stay in it for a long time and need fresh air.

2. Installation position of fresh air main engine

The fresh air main machine is generally installed on the ceiling of the kitchen and bathroom, which does not occupy extra space and is hidden, and does not affect the indoor beauty. The splitting machine is generally installed at the lower part of the window sill, which is convenient for maintenance and does not affect the curtains.
