Technical field
The invention belongs to polymer composite material field, more particularly to hydrophily, high heat conductance composite, tool
Body is a kind of Total heat exchange film and preparation method thereof, further relates to a kind of Total heat exchange core body including the Total heat exchange film, a kind of
Total-heat exchanger and a kind of air-treatment unit including Total heat exchange core body including Total heat exchange core body.
Background technology
With requirement of the people to air quality and the development of passive building technology, improving energy utilization rate simultaneously improves air matter
Amount becomes one of green building field focus.During new blower fan use, for the energy consumption often duty of Fresh air handing
Adjust more than the 30% of total energy consumption.Fresh air-changing device technology improves a lot in recent years, and which is usually by fresh air pipeline and interior
Exhaust duct carries out heat exchange to realize the effect of energy saving.It is using total-heat exchanger, mixed with what is discharged by fresh air
Turbid air carries out energy on Total heat exchange film and humidity is exchanged, and air energy in building and humidity can be adjusted and is returned
Receive, so as to effectively realize the target of building energy-saving reduction of discharging.Therefore, Total heat exchange technology has been increasingly becoming building energy saving field weight
One of point research direction.
At present, using aluminium core is fast and refill block more than the heat exchange pellet of existing new blower fan, aluminium core block is applied to Exchange of apparent heat
Device, it is impossible to carry out humidity i.e. latent heat and exchange；Refill block is applied to total-heat exchanger, but one side Exchange of apparent heat is not so good as aluminium core,
