Fresh air purification unit system and operation control method thereof

The invention discloses a fresh air purification unit system. The unit system comprises a main body and a full-heat heat exchanger arranged in the main body. A purification module, a heat exchange module, a second electric heating module, a humidification module, a blower and an air supplying opening are arranged in sequence along an air supply direction of an air supply channel. Based on monitored inlet air temperature T3, indoor dew point temperature Tw, outdoor ambient temperature T4, supply air temperature T2, indoor temperature T1, indoor humidity H1, indoor PM2.5 and indoor CO2 and otherparameters, a series of control actions are carried out on the unit system to ensure that the indoor environment is at a reasonable indoor temperature, humidity, cleanliness and oxygen content, and to create a comfortable indoor environment. At the same time, the unit system is activated and dynamically adjusted on demand, can save more energy, and is reliable. 本发明公开了一种新风净化机组系统，包括主体和设于主体内的全热换热器，沿送风通道的送风方向依次排列布置有净化模块、换热模块
