Described air outlet is circular.
On described filtering module side housing, establish screen pack extraction opening.
On described pressure fan, be provided with condensate water discharging mouth.
In described exhaust blower electric cabinet and pressure fan electric cabinet, all establish power supply and controller.
Super new blower for heat recycling of the present invention, pressure fan is transferred to air-supply end by the energy of air draft place by freon by the driving of compressor by the principle that copper pipe is connected, freon circulation, similar air-conditioning are walked in inside with exhaust blower. Due to the general indoor air temperature outdoor air of comparing, lower winter in summer is higher, can greatly improve so overall COP value, has solved the problem of room air recuperation of heat from cardinal principle.
Beneficial effect: compared with prior art, heat recovery efficiency of the present invention improves greatly, and COP value is up to 5 or 6; New wind wind pushing temperature is controlled; Adopt split-type structural can reduce equipment volume and save installing space; Can dehumidify summer to new wind, reduces new rheumatism degree, has good practicality. The common board-like or runner of the tradition of comparing is depended merely on this kind of mode heat recovery efficiency of recuperation of heat (theoretical value can not be greater than 100%) that difference in air temperature brings can be up to 500-600%.
