Vertical fresh air ventilator (XHL series) works when the indoor air conditioning return air and fresh air was positively cross-way through the heat exchanger, due to the flat baffle temperature difference exists on both sides of the airflow and water vapor partial pressure difference, the two share between airflow while producing heat and mass transfer, causing total heat exchange process. This process is accomplished through the flat separator, therefore, is a transmission type total heat exchange. When installed on a system-wide run in the summer heat, get fresh air from the air conditioning return air in the cold, the temperature is lowered, and was back to dry heat recovery fresh air ventilation maintenance crew, so that the new air humidity decreases; running in the winter When, get fresh air from the air conditioning return air in the heat, the temperature rises, the return air humidification simultaneously. Is the total heat exchange through this process, so that the new wind energy recovered from the air conditioning return air. Features new wind ventilators: 1, displacement ventilation features fresh outdoor air into the room, while the polluted indoor gas outside. Renewal, giving you exposure to nature in comfort. 2. Built-in energy recovery heat recovery equipment, the exhaust air to the incoming air and send the energy exchange (temperature, humidity) heat recovery ventilation unit, more than 70% of the energy recovery ventilation makes the insulation becomes a reality . 3, quiet design special low noise fan built-conditioned fresh air heat recovery ventilation unit manufacturers, machine housing wall covered with the new sound-absorbing material, all mute design, human expression. Heat recovery ventilation unit maintenance _ Cangzhou fresh air ventilation heat recovery unit _ liter by liter Swiss Swiss Mechanical and Electrical HVAC Electrical Equipment Factory.
