The indoor unit top is equipped with miniature air intake blower fan, and the indoor unit lower part is equipped with miniature exhaust fan, the miniature air inlet wind
Machine, the miniature exhaust fan are electrically connected with control flow respectively；The miniature air intake blower fan is located at fresh air outlet outside, described micro-
Type exhaust fan is located at outside air draft entrance.
Further, the both ends of the ventilation duct are respectively equipped with end cap.
Further, fresh air strainer is equipped between the miniature air intake blower fan and fresh air outlet.
Further, the lower section of the miniature exhaust fan is equipped with air draft strainer.
Further, the thermal sheet is waveform.
Further, the top and bottom of the indoor unit are equipped with Electric air valve, the Electric air valve and the control
Screen electrical connection.
The utility model has the beneficial effects that the household fresh air fan of the utility model is by ventilation shaft (fresh air pipeline, air-exhausting duct
Road) and heat exchanger be integrated.Heat exchange is completed during air inlet and air draft, and due to air inlet direction and air draft side
To being opposite, so heat exchange effect is good, can allow into room fresh air temperature close to room air, not will cause
Too big thermal losses, the season big especially suitable for winter, Xia Liangji indoor/outdoor temperature-difference.And a hole need to be only opened on metope,
Simple installation can achieve the purpose that air inlet and air draft in the case where closing the doors and windows.
