Background
Because the human body and indoor equipment are generating pollutants at any time. The concentration of contaminants in the enclosed room will be higher and higher. The main measure for ensuring the indoor air quality is ventilation, i.e. the replacement of the indoor air containing contaminants with outdoor air having very low contaminants.
In the existing house construction, due to the problems of building materials and tightness, the ventilation performance is poorer and poorer, the air quality in the house is lower and lower, and the ventilation requirement of a user cannot be met; and the poor indoor co-room performance often causes the following problems:
first, bacteria grow quickly and room mildew smell can be very heavy.
Secondly, the dry environment can lead to dry mouth and tongue and sore throat when the device stays in a room with a radiator for a long time.
Thirdly, the syncope caused by cerebral blood supply insufficiency can be caused by overlong time, and the syncope can be quickly transferred to an air circulation place to be recovered. It is recommended that the ventilation be timed by opening the vent to open the door.
Fourth, most ventilation fans can not be automatically adjusted along with temperature change, and a resident is required to automatically control and adjust the ventilation device, so that a small part of products can adjust the air quantity according to the temperature in time, and a thermosensitive spring is generally selected, so that faults often occur during use.
