Total heat recovery energy efficient new concept of energy-saving high-tech nano membrane technology vendor of choice for the new wind ventilators, level reverse convection technology, antistatic maintenance-free technology, muffler technology applications, so that fresh air ventilator breaking the traditional heat recovery efficiency of the common low technical bottlenecks, total heat recovery efficiency of more than 75% energy saving new wind ventilators, exhaust energy recovery greatly improved, with the new wind ventilators, not only can reduce the amount of air conditioning capacity and equipment host one-time investment, but also can reduce the overall system operating costs of new wind ventilators basic structure a heat exchange system currently, both at home or abroad, in the fresh air ventilator used in stationary and rotating heat exchangers have two forms in which the runner heat exchange also belong to the rotary type. From normal use and maintenance point of view, still better than the rotary type, but more than 2 × 10000m3 / h mainframe for new energy-saving air ventilator customized, generally rely Rotary heat exchanger can be achieved, it can be said static and rotary advantages and disadvantages. For ease of flow channel is arranged inside the device, in order to reduce the overall volume of fresh air ventilator with a cross-flow, static plate heat exchanger. Namely: the direction perpendicular movement of hot and cold gas, which belong to the convective heat transfer properties of the turbulent flow within the boundary layer. Therefore, sufficient heat exchange can achieve higher energy efficiency.
