CHAPTER 5
System Design Recommendations
1. Lossnay Usage Conditions
Commercial-use Lossnay
In some cases special attention needs to be paid to extreme operating conditions.
These are described as below:
1.1 Use in cold climates (outdoor temperature: –5°C or less)
Plot the Lossnay intake air conditions A and B on a psychrometric
chart as shown on the right. If the high temperature side air B
intersects the saturation curve such as at C, moisture
condensation or frosting will occur on the Lossnay. In this case,
the low temperature side air A should be preheated to the
temperature indicated by point A' so that point C shifts to the point
C'.
1.2 Use in high humidity conditions (Relative humidity: 80% or more)
When using the system in high humidity conditions such as heated pools, bathrooms, mushroom cultivation houses, high-fog
areas etc., moisture will condense inside the Core, and drainage will occur. In these cases, the general purpose Lossnay that
uses treated paper cannot be used.
1.3 Use in other special conditions
The Lossnay cannot be used where toxic gases and corrosive element's such as acids, alkalis, organic
solvents, oil mist or paints exist.
Use where heat is recovered from odor-laiden air and supplied to another place (area) is not possible.
Avoid use where salt or hot water damage may occur.
Pre-heating is necessary if using the system in a cold climate (locations where winter temperatures are below
-15°C).
Refer to page 144 to set up the heater.
