New wind ventilators new wind power section ventilator system uses a high power efficiency, lower noise fan. The filtered, purified and the heat exchange process mandatory outdoor fresh air into the room, while the filtered, indoor harmful gas purification and heat exchange process after compulsory exhausted to the outside. So, Wall new wind ventilators, air-conditioning energy-saving equipment Dingrui heat is energy-saving products, users can enjoy pleasant economical and efficient fresh air. With "air - conditioning system" design, consider using the total heat exchanger, not only can reduce the air conditioner capacity, new wind ventilators, but also can reduce their operating costs. For example, a building cooling load calculation is 260w / m2, where the fresh air of 30m3 / h, the fresh air is needed per square meter 6 m3, ie 7.2kg / m2. Summer when the outdoor temperature is above 38 ℃, ceiling total heat fresh air ventilators, the indoor temperature at about 26 ℃, indoor and outdoor enthalpy difference of about 40kj / kg, the new wind load of about 80W / m2. The new wind ventilators, Dingrui air conditioning, ceiling type air ventilator quotes provided by wucheng Dingrui air-conditioning Limited.
