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, bi-directional displacement ventilation while Shandong fresh air ventilator, generate energy exchange, so that effective access to fresh air ventilation in the enthalpy (total heat type) or temperature (sensible heat type) Nanjing new wind ventilators, thus saving energy consumption of fresh air 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 new wind ventilators total heat, becoming the most competitive on the market fresh air ventilator products. The difference between fresh air ventilator and air purifier: air purifier is a closed circulation system, can only reduce some of the content of harmful substances in indoor air, can not reduce the concentration of carbon dioxide can not be supplemental oxygen, can not meet the IAQ (Indoor Air Quality ) for fresh air requirements. Fresh air ventilator is an open circulatory system, can provide enough fresh air for the interior to protect the people in the room to breathe fresh, clean air. At the same time, fresh air ventilator wind through old and new replacement, reducing the content of harmful substances in indoor air, in large part also had the effect of air purification. Beijing's new wind ventilators, ventilation equipment Plumper (certified), fresh air ventilator provided by Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (www.frtfsb.com) is a leader in Dezhou, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Rich ventilation equipment in leadership with the staff warmly welcome all inquiries negotiations to create rich, ventilation a better future.
