For fresh air ventilator heat exchanger, we at the time of application should choose those small size, light weight and high heat transfer efficiency. And to note that there is a new wind ventilators specifications, along with the air flow through the heat exchanger when the pressure loss is smaller ceiling fresh air ventilation machine manufacturers, otherwise the price of fresh air ventilator, heat exchanger to recover compensation is less than the new wind energy ventilators consumed energy. So to start is not the same type of heat exchanger discussion, we believe that the new air ventilation engineering supply technical reserves. I hope the above application of knowledge about the new wind ventilators are able to better help you understand the new heat recovery ventilation unit through a heat recovery exchanger fresh outdoor air into the room, while the indoor polluted gas into the room, two-way ventilation, air purification, energy recovery and other functions, renewal. So you have exposure to nature comfort. Unit is suitable for conference rooms, laboratories, offices, rooms, catering, restaurants, hotels, stadiums, shopping malls and other comfort air conditioning systems; also widely used in electronics, chemicals, health care, bio-manufacturing, car parks, basements and other air conditioning system, instead of the new fans and ventilation machines use more energy-efficient, environmentally friendly, durable, and can enhance the style and style air-conditioned environment of the scene, creating a more comfortable working and living environment. Floor-liter fresh air ventilator _ Swiss mechanical and electrical (certified) _ Beijing fresh air ventilator ventilation and air conditioning provided by the Swiss liter Electrical Equipment Factory.
