New wind energy recovery ventilator is a highly efficient energy-saving air conditioning and ventilation system, divided CHA and CHB total heat recovery type heat recovery type, its core function is to use the indoor and outdoor air temperature difference and humidity difference, the movement through energy recovery Good transducer characteristics of fresh air ventilator manufacturers, bidirectional displacement ventilation, while generating energy exchange, so that new wind effective access to exhaust the enthalpy (total heat type) or temperature (sensible heat type), thus saving the fresh air energy pretreatment to achieve the purpose of energy saving ventilation, energy saving effect is very significant. Over the years of technical research and development, successfully developed the third generation of new wind energy recovery ventilators, its movement using the latest technological achievements - Energy Recovery Module WASSI-III, WASSI-III superior performance of the third generation of new wind energy recovery change air machines on the technical indicators are beyond the previous models, the most competitive on the market fresh air ventilator products. Heat exchange system is currently fresh air ventilator, whether at home or abroad, in the fresh air ventilator using stationary and rotating heat exchanger has two forms which belong to Rotary rotary type heat exchanger. From the perspective of normal use and maintenance of the total heat fresh air ventilators, still better than the rotary type, but more than 2 × 10000m3 / h mainframe, the general can only be achieved by Rotary heat exchanger, it can be said static and rotary advantages and disadvantages. For ease of flow channels of the best quality fresh air ventilator arranged inside the device, in order to reduce the overall volume of fresh air ventilator using 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. The new wind ventilators price _ Rich ventilation equipment (certified) _ fresh air ventilator provided by Dezhou Plumper ventilation plant.
