A. Compressor M1C
Scroll compressor that operates on 30~116Hz by inverter drive enables 13-step capacity control.
Capacity control is carried out for individual and linear control of indoor units.
B. Oil separator
The oil separator is a device that collects the oil discharged from the compressor.
The collected oil is constantly recycled to the compressor via capillary tube.
C. Solenoid valve (hot gas bypass) Y2S
Valve is opened by low pressure safety control when low pressure drops.
Balances high/low pressure when off in order to reduce load when the compressor starts.
D. Outdoor unit electronic expansion valve Y1E
Expansion valve is kept open.
E. Solenoid valve (injection) Y3S
Controls injection in order to prevent overheating.
F. Heat exchange pipe
Subcools so that refrigerant drift doesn't occur between indoor units when flash gas is produced in the
liquid pipe.
G. Pressure sensor (high pressure, red) SENPH
Semiconductor pressure sensor carries out heat exchange control during low outdoor cooling operation by
sensing discharge pressure.
H. Pressure sensor (low pressure, blue) SENPL
Semiconductor pressure sensor for sensing the operating status of the indoor by refrigerant pressure
which senses suction pressure.
