How does a fresh air ventilator work?
Energy recovery fresh air ventilator is a high-efficiency energy-saving air-conditioning ventilation device, which is divided into full heat recovery type (full heat exchanger) and sensible heat recovery type (sensible heat exchanger). Its central function is to use indoor and outdoor air. Temperature difference and humidity difference, through the good energy conversion characteristics of the energy recovery movement, energy exchange occurs at the same time as two-way displacement ventilation, so that the fresh air can effectively obtain the enthalpy value (full heat type) or temperature (sensible heat type) in the exhaust air, As a result, the energy consumption of the fresh air pretreatment is greatly saved, and the purpose of energy saving and ventilation is achieved, and its energy saving effect is very significant.
After years of technological research and development, the third generation of energy recovery fresh air ventilator has been successfully developed. Its movement selects the latest technological achievements-the energy recovery module WASSI-III. The superior performance of WASSI-III enables the third generation of energy recovery fresh air replacement. The gas turbine has surpassed the previous models in various technical goals and has become the most competitive fresh air ventilator product on the market.
