-- total heat recovery device 2 (preferably paper honeycomb heat exchanger), its respectively with return air chamber 11, fresh air chamber and air draft chamber 13
It is connected；
-- the evaporator section 31 of heat exchange of heat pipe 3, it is connected with total heat recovery device 2；
-- surface cooler 4, it is connected with the evaporator section 31 of heat exchange of heat pipe 3；
-- evaporator 5, it is connected with the surface cooler 4；
-- condenser 9, itself and the diconnected of evaporator 5, form closed-loop refrigeration cycles；
-- the condensation segment 32 of heat exchange of heat pipe 3, it is connected with evaporator and wind pushing cavity 14 respectively；
Room air can flow through return air chamber 11, total heat recovery device 2 and air draft chamber 13 successively；Outdoor air can flow successively
Through fresh air chamber 12, total heat recovery device 2, the evaporator section 31 of heat exchange of heat pipe 3, surface cooler 4, evaporator 5, the condensation segment of heat exchange of heat pipe 3
32 and wind pushing cavity 14.
Fresh air ventilator provided by the present invention can control flow of outside air to carry out the drop of precooling first through total-heat exchanger
It is wet, then flow through the evaporator section 31 of heat exchange of heat pipe 3 and carry out secondary precooling wet down, then flow through surface cooler 4 and evaporator 5 carry out it is cold
Freeze dehumidifying, dehumidifying step by aforementioned four can be by the air humidity got in control in expected scope；It is and indoor
Air, which can flow through return air chamber 11, total heat recovery device 2 and air draft chamber 13 successively, to discharge outdoor by the moisture of interior.One enters one
Going out an even distinguished and admirable path effectively realizes the purpose to be dehumidified to interior, and significant effect, can be by air dew point temperature control
System is below 10 DEG C.To avoid the too low influence indoor comfort of wind pushing temperature, air uses before being sent into interior after by dehumidifying
The condensation segment 32 of heat exchange of heat pipe 3 is heated, so that air reaches appropriate temperature (20 DEG C -22 DEG C).
Above-described embodiment is only capable of reaching the effect for dehumidifying to room air, can not reach the effect of purification air.
In order that the air got in has preferable quality, the embodiment of the present invention also includes：
-- roughing efficiency air filter 6, it is connected with the condensation segment 32 of heat exchange of heat pipe 3；
-- PM2.5 filters 7, it is connected with roughing efficiency air filter 6, wind pushing cavity 14 respectively；
Outdoor air flows into wind pushing cavity 14 after flowing through roughing efficiency air filter 6 and PM2.5 filters 7 successively.Outdoor air is through removing
It has passed through before being got in after wet and successively filtering of the roughing efficiency air filter 6 to bulky grain floating object, and PM2.5 filters 7 are right
The filtering of haze particle, so that the air quality for being passed through interior is clean, the living environment of cleaning is provided the user.
Preferably, the fresh air ventilator that the embodiment of the present invention is provided also includes：
