5. EFFICIENCY AND FAN CURVES
5-1. Efficiency Calculation
The Lossnay Core’s energy recovery efficiency can be considered
SA
using the following three transfer rates:
(1) Temperature (sensible heat) recovery efficiency
(2) Humidity (latent heat) recovery efficiency
(3) Enthalpy (total heat) recovery efficiency
The energy recovery effect can be calculated if two of the above
efficiencies are known.
Fresh air
exhaust
(Fresh
heating/
cooling
air)
Indoors
Each energy efficiency can be calculated with the formulas in
•the
table.
the supply and exhaust air volumes are equal, the energy
•When
recovery efficiencies on the supply and exhaust sides are the
•
same.
When the supply and exhaust air volumes are not equal, the
total energy recovery efficiency is low if the exhaust volume is
RA
lower, and high if the exhaust volume is higher.

Calculation of Supply Air Condition After Passing Through Lossnay
If the Lossnay energy recovery efficiency and the conditions of the room and outdoor air are known, the conditions of the air
entering the room and the air exhausted outdoors can be determined with the following formulas in the following table.
Temperature
Enthalpy
Supply Side
Exhaust Side
tSA = tOA - (tOA - tRA) × ηt
tEA = tRA + (tOA - tRA) × ηt
iSA = iOA - (iOA - iRA) × ηi
iEA = iRA + (iOA - iRA) × ηi

When the OA temperature falls below 14° F (-10° C) during operation, the SA-fan will change to intermittent operation.
OFF for 10 minutes, ON for 60 minutes. Operation below 14° F is not reccomended without the use of a preheat coil to
maintain outdoor air inlet conditions above 14° F. When outdoor temperature falls below 5° F the unit will cycle off.
The unit will cycle back on 5 minutes out of every 60 minutes to determine if outdoor air temperature is above 5° F.

saturation curve such as at C, moisture condensation or frost will
build on Lossnay. In this case, the low temperature side air A
should be warmed up to the temperature indicated by Point A’ so

8. VENTILATION CONSIDERATIONS
Room air ventilation requirements are often governed by local state code. State codes typically reference the International
Mechanical Code (IMC). This standard defers to and references within “ASHRAE Standard 62.1 Ventilation for Acceptable
Indoor Air Quality”.
Standard 62.1 prescribes through its prescriptive compliance path ventilation rates for specific types of building spaces in order
to maintain contaminant levels from off gassing of materials and bio-effluents from building occupants at acceptable levels as
governed by the standard. Contaminants controlled by this standard include Ammonia, Benzene, Carbon Monoxide, Formaldehyde, TVOC, and several others.
It is important in any HVAC system design to ensure that these minimum ventilation rates are maintained or controlled based on
occupancy during occupied hours in order to comply with this standard and maintain acceptable indoor air quality for building
occupants.
A sample of typical ventilation rates required for some common building spaces per ASHRAE Standard 62.1-2010 are listed in
the table below. Always consult local code / jurisdiction for specific requirements at location of project.

The uncorrected ventilation rate (Breathing Zone Outdoor Air – Per ASHRAE 62.1) for a give space per this standard,
referencing the above table, would then be:
Uncorrected Space Ventilation
= (# of People) x (CFM/person from table) + (Space Area, ft2) x (Area rate, CFM/ft2 from table)
(CFM)
Other corrections to this ventilation rate must be made per the ASHRAE 62.1 standard for Air Distribution Effectiveness,
Multiple-Zone Correction, as well as Occupant Diversity. Consult Chapter 6 of ASHRAE 62.1 for a complete explanation
of these corrections.

9-2. Supplemental Fan Devices
Installing Supplementary Fan Devices
On occasions it may be necessary to install additional fans in the ductwork following LGH-type Lossnay units because of the
addition of extra components such as control dampers, high-efficiency filters, sound attenuators, etc. which create a significant
extra static pressure to the airflow. An example of such an installation is as shown below.

(1) Always leave an inspection hole ( 18) to access the filter and Lossnay Core.
(2) Always insulate the two ducts outside the room (intake air and exhaust air ducts) to prevent frost from forming.
(3) Prevent rainwater from entering.
Apply a slope of 1/30 or more towards the wall to the intake air and exhaust air ducts outside the room.
Do not install the vent cap or round hood where it will come into direct contact with rainwater.

There is an increased use of air conditioning systems with independent multiple air-conditioner unit due to their features such as
improved controllability, energy conservation and saving space.
For these types of air conditioning systems, combining the operation of the dispersed air conditioners to Lossnay is possible.

10. FROST PREVENTION
Under the following conditions, Lossnay will force stop of the air supply fan. However, when the following
conditions are met while operating at Extra Low fan speed, the air supply fan will stop, and the exhaust fan
will operate at Low fan speed.
(When operating at Extra Low fan speed, the air supply fan and the exhaust fan cannot be stopped
separately.)
When P-Series is in defrost or stopped due to a fault, in an interlocked system with P-Series that has a
duct connection with Lossnay.
(For cold inrush prevention, or falling dust prevention)
When the indoor unit is in defrost, in an interlocked system with a CITY MULTI indoor unit that has a duct
connection with Lossnay.
(For cold inrush prevention)
When the outside temperature is 14° F (-10° C) or lower, the air supply fan is stopped periodically for
approximately 10 minutes to 55 minutes. Operation below 14° F is not recommended without the use
of a preheat coil to maintain outdoor air inlet conditions above 14° F. When outdoor temperature falls
below 5° F the unit will cycle off. The unit will cycle back on 5 minutes out of every 60 minutes to
determine if outdoor air temperature is above 5° F. Operation below 14° F is not recommended
without the use of a pre heat coil to maintain outdoor air inlet conditions above 14° F.
When outdoor temperature falls below 5° F the unit will cycle off. The unit will cycle back on 5 minutes
out of every 60 minutes to determine if outdoor air temperature is above 5° F.

recommendation
(RECOMMENDED, VENTILATION
When PZ-60DR-E is used and the ventilation mode is set to Lossnay ventilation or bypass ventilation,
“RECOMMENDED” and “VENTILATION MODE” may be displayed alternately (for 10 minutes maximum).
This function informs the user of the suitable ventilation mode according to the automatic ventilation algorithm. When a ventilation mode change recommendation has been displayed, more comfortable ventilation
can be provided by pressing the “Function selector” button of the remote controller and switching to another
ventilation mode.
(We recommend that “AUTO” be selected for the ventilation mode; however, there is no problem in leaving
the ventilation mode unchanged with “RECOMMENDED” “VENTILATION MODE” displayed.)
(5) Interlocking with external devices

The system will interlock with the following input signals from external devices and start/stop.
Multiple units systems having multiple Lossnay units, input the signal to the “Main” Lossnay.
