QS MPS(Switching Mode Power Supply) Part Description
1. BRIDGE DIODE (BD71) provides full wave reification from AC input. Then
smooth it with Electrolytic Condenser(C101). Smooth voltage is similar to the
results of AC input x1.414. (Ex: When AC220V is supplied, 220×1.414 = about
DC310V)
2. The main power supply of ventilator is DC310V as it utilizes BLDC MOTOR.
3. PWMIC (IC01) switches smooth DC voltage, which is, in turn, induced to
secondary side, so as to generate DC15V (C104) and
DC12V(C107). 4. The voltage of secondary side is decided by TURN numbers of
TRANS winding. DC 15V is utilized only for CONTROL power source
of BLDC MOTOR while DC12V is used for power source of CO2 sensor. 5. When BLDC
MOTOR faulty takes place, DC 15V or DC 12V might not be generated. 6.
SWITCHING DIODE of secondary side should not utilize usual rectification DIODE
because SWITCHING speed of SMPS reaches
130kHz. High speed SWITCHING DIODE is required. 7. SMPS stops operation if
SHORT occurs post voltage of DC12V because of FEEDBACK from DC12V.

QM otor Load(BLDC : BRUSHLESS MOTOR) Part Description
1. Smooth DC310V of electrolytic condenser (C101) is utilized for operation
power source. 2. DC15V (C104) of secondary side of circulation is used for
CONTROL voltage of MOTOR. BLDC CONTROL voltage must be lower
than MAX DC18V. 3. CONTROL voltage is distributed through No.5 PIN of CN73 and
is lower than MAX DC7V. MOTOR RPM is determined by
DC0V~DC6V voltage. 4. No. 6 PIN of CN73 is the RPM FEEDBACK POINT, which
delivers MOTOR rotation to MICOM. If DC15V continues to be found when
measuring DC15V and No.6 PIN, FAN MOTOR ERROR occurs because FEEDBACK is not
conducted. 5. CONNECTOR of CN73 is dislocated when PCB power source is
authorized, DC310V voltage may flow into CONTROL IC within BLDC
in a moment, damaging CONTROL IC of BLDC. It may cause SHORT of DC15V or
DC310V. 6. If SHORT of DC15V or DC310V takes place, 2A FUSE (F702) opens and
DC15V rectification DIODE may be damaged, which stops
operation of SMPS.

10-1-1 Operation Principle
Q Purpose : The ventilator aims at enhancing indoor air quality with utilizing
fresh outdoor air. (At this section, only technological explanation is
provided.)
Q Process : The ventilator supplies outdoor air and exhaust indoor air. Q Air
Volume : The volume is determined according to volume of supply air or exhaust
air. It is indicated with CMH
(Cubic Meter per Hour).
10-1-2 Additional Function
Q The unit supports Heat-EX mode and By-Pass mode (selected by DAMPER). Q
Heat-EX mode : Temperature and humidity of indoor air and outdoor air are
exchanged
(The function minimizes heat loss from the process of ventilation). Q By-Pass
mode : Ventilation process without exchanging heat of indoor and outdoor air.
