The invention relates to the field of indoor air ventilation, in particular to a window frame surrounding heat recovery type fresh air ventilator. The window frame surrounding heat recovery type freshair ventilator comprises a shell-shaped window frame. An air pipe set for air circulating is arranged in an inner cavity of the window frame and comprises a fresh air pipe and an exhaust air pipe. The outdoor lateral wall of the window frame is provided with a fresh air inlet and an exhaust air outlet. The indoor lateral wall of the window frame is provided with a fresh air outlet and an exhaustair inlet. One end of the fresh air pipe communicates with the fresh air inlet, and the other end of the fresh air pipe communicates with the fresh air outlet. One end of the exhaust air pipe communicates with the exhaust air inlet, and the other end of the exhaust air pipe communicates with the exhaust air outlet. A fan module is arranged between the fresh air pipe and the fresh air inlet / fresh air outlet. Another fan module is arranged between the exhaust air pipe and the exhaust air inlet / exhaust air outlet. Due to arrangement of the air pipe set, exhaust air and fresh air can be subjectedto primary heat exchange through the outer wall of an air duct, heat exchange is reinforced through a communication pipe with fins, and therefore the purpose of recycling cold capacity and heat capacity of the exhaust air is achieved.
Description
technical field [0001] The invention relates to the field of indoor ventilation, in particular to a ring window frame heat recovery fresh air fan. Background technique [0002] Now the environmental quality is very poor, smog weather occurs frequently, and there is a lot of dust in the air, which seriously affects human health. In order to improve the air quality, people usually choose an air purifier to purify the air in the room. However, most of the air purifiers currently on the market are placed indoors and do not have a ventilation function. If you do not open the windows for a long time to ventilate, the oxygen content in the indoor air will be greatly reduced, and the carbon dioxide content will gradually increase. In addition, indoor decoration materials and harmful gases produced in the living process will cause users to feel dizzy and lack of energy indoors. Wait for discomfort. If the windows are often opened for ventilation, the purification effect of the air...
