1. Health, environmental protection, energy efficient 2. Alone, independent control. 1. Full air quality, all healthy breathing. All the indoor heat exchanger is to provide fresh air while the indoor polluted air exhausted to the outside of the ventilation equipment in the room while providing fresh air, fresh outdoor air and indoor air pollution within the heat exchange in heat exchanger, recovery room polluted air, heat, moisture, ensure stability in the indoor air condition.2. Health, environmental protection, energy efficient in heating the indoor air emissions from recycling 90% of the heat, cooling capacity 80% recycled heat, saving heating and cooling energy use up to 28% of mice. 3. Alone, independent control. By HQR line device to achieve the following features three operating modes, automatic mode, heat exchange mode and bypass mode four kinds of wind speed: high wind, low wind, high for the wind and low for the wind.
