Lossnay Q and A
Question
Answer
Remarks
1
Lossnay plate is used for
the material, but does it
have an adequate life span?
The core will last an adequate amount of time unless it is intentionally
damaged, placed in water or in direct sunlight (ultra-violet rays).
The life is longer than metal as it does not rust.
Depending on
conditions, the core
material can be stored
for up to 2,000 years
without deteriorating.
2
Is the Lossnay plate an
insulation material? (Poor
conductor of heat)
The plate is very thin, and thus the conductivity of the material is low, with
heat being transferred approximately the same as metal. This can be tested
placing a piece of paper between hands and feel the warmth of the palms.
The recovery of humidity can also be felt by blowing on the paper and feeling
the moisture in the breath being transferred to the palm.
3
If the Lossnay plate can
recover humidity, will it not
become wet?
It is similar to the phenomenon during heating in winter where the window
pane is wet but the paper blinds are dry - humidity is transferred through the
plate.
4
When is the forced
simultaneous air intake/
exhaust-type more
efficient?
When a building is sealed and normal ventilation is used, accurate exhaust is
not possible unless a suction inlet is created.
Forced simultaneous air intake / exhoust is possible because Lossnay units
have both an air-supply fan and air-exhaust fan.
5
What are the energy
conservation properties of
Lossnay units?
For an example, in an approx. 140ft
2
(13 m
2
) room with five people, a
ventilation volume of 75 CFM (127 m
3
/h) is required. The amount of power
consumed in this case is approximately 45 W, and the amount of energy
recovered during cooling is approximately 700 W or more. The coefficient of
performance (C.O.P.) obtained when converted with the unit power
generation amount is 16. When compared to a popular heat pump has a
C.O.P. of 2 to 3, the Lossnay can serve a high amount of energy.
If a general-purpose ventilator is installed, the cooled air will be lost, thus
increasing electrical costs throughout the year.
