Total Energy Recovery Mechanism
Sensible Heat and Latent Heat
The heat that enters and leaves in accordance with rising or falling temperatures is called sensible heat. The direct movement of
water vapor molecules or due to the changes in the 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 in the diagram at right, the energy recovery
efficiency is affected by the resistance of the partition plate.
For Lossnay, there is little difference when compared to
materials such as copper or aluminium that also have high
thermal conductivity.

(2) Humidity (Latent Heat) Recovery
Water vapor travels through the partition plate from the high
humidity to low humidity side via the differential pressure in
the vapor.
