A comparison of the ordinary paper and the Lossnay Core plates is as shown in the table.
Water vapor is transferred, but gas elements that are easily
dissolved in water such as CO
The contaminated air passes through the plates during
ventilation and returns to the room.

The contaminated air does not return to the room when
ventilated.
Total heat recovery mechanism
Sensible heat and latent heat
The heat that enters and leaves in accordance with changing temperature (rise or drop) is called sensible heat. The heat that
enters and leaves due to the changes in a matter's physical properties (evaporation, condensation) is called latent heat.
(1) Temperature (sensible heat) recovery
1) Heat conduction and heat passage is performed through a
partition plate from the high temperature to low temperature
side.
2) As shown on the right, the heat recovery efficiency is affected
by the resistance of the boundary layer, and for the Lossnay
there is little difference when compared to materials such as
copper or aluminium which also have high thermal
conductivity.

(2) Humidity (latent heat) recovery
Water vapor is moved through the partition plate from the
high humidity to low humidity side by means of the
differential pressure in the vapor.
