According to the indoor air quality data fed back by the CO2 sensor 18 and the formaldehyde detection device, the fresh air fan can operate in three modes. The solubility of CO2 and the solubility of formaldehyde in outdoor normal air are defined as I grade, and the indoor air quality is divided into three grades of I, II and III.
When the indoor formaldehyde and CO2 are low in solubility, the air quality is I low-grade and I grade (I low-grade air quality is better than I grade); indoor formaldehyde and CO2 are in class II (classified into class II low and class II high) when the solubility (one or two of them) is high; indoor formaldehyde, CO2, is class iii (classified as low class iii and high class iii) when the solubility (one or both) is high.
When the indoor air quality is I level, the fresh air fan is started to be in a full return air mode. In the mode, the feedback values of the CO2 sensor 18 and the formaldehyde detection device are both low but slightly higher than the outdoor, the controller 20 sends an instruction, the return air control valve is opened to the lower part, the return air channel is opened, the exhaust air duct 25 is closed, the high wind gear is opened by the air supply fan 7, and the exhaust fan 9 is closed. Indoor return air enters the circulating air duct through the return air inlet 19, firstly impurities such as hair and cotton wool in the air are filtered through the coarse filter screen 12, then dust with small diameter is filtered through the middle filter screen 13, and the return air which is filtered through coarse and middle effects under the action of the air supply fan 7 is efficiently filtered through the electrostatic dust removal device.
The return air subjected to multi-stage filtration has high cleanliness, but bacteria, formaldehyde and the like in the return air cannot be effectively removed. An ultraviolet irradiation lamp 4 and a photocatalyst net are arranged after electrostatic dust collection, bacteria in the air can be effectively inactivated, the return air after sterilization is adsorbed by the activated carbon filter screen 2, and clean air is delivered into a room through the air supply outlet 23. When the indoor air quality is detected to be I low, the new fan stops working.
When the indoor air quality is level II, the fresh air fan is started to mix air. In the mode, the solubility of one or two of CO2 and formaldehyde is high, the fresh air valve 14 and the return air valve 16 are driven downwards under the control of the controller 20, the high air gear of the air supply fan 7 is opened when the air quality is detected to be II high, the low air gear of the air supply fan 7 is opened when the air quality is detected to be II low, and the exhaust fan 9 is closed. Outdoor new trend passes through fresh air inlet 11, mixes with indoor return air behind thick, medium efficiency filter screen 13 and the total heat exchange core 15 in proper order, and the air after the mixture is sent into indoorly through multilevel processing, can judge the clean degree of air through PM2.5 detection device. When the indoor air quality is detected to be I low, the new fan stops working.
When the indoor air quality is level III, the fresh air fan is started to be in a fresh air mode. The indoor CO2 solubility and formaldehyde solubility are reduced by introducing outdoor fresh air. Under the control of the controller 20, the fresh air valve 14 is opened downwards, the return air valve 16 is opened leftwards, the high windshield is opened for the air supply fan 7 and the air exhaust fan 9 when the air quality is detected to be III high, and the low windshield is opened for the air supply fan 7 and the air exhaust fan 99 when the air quality is detected to be III low. The indoor return air and the outdoor fresh air are subjected to energy transfer at the total heat exchange core body 15, the indoor return air is exhausted outdoors through the exhaust fan 9, and the outdoor fresh air is sent indoors after being subjected to multi-stage filtration and sterilization by the air supply fan 7. When detecting that indoor air quality is I low or is close to I low, new fan stop work.
It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
