A. Compressor
Controls capacity of 0 - 45 - 100% by combination of constant speed type compressors 1 and 2.
Compressor is equipped with an oil discharge function for draining excess oil from the high pressure side.
B. Check valve
Prevents refrigerant from collecting in the constant speed type compressor 2 when operating constant
speed type compressor 1 only.
C. Check valve
Installed so that constant speed type compressor 1' s oil discharge function functions properly.
D. Oil separator
Device which collected oil discharged from the compressor and returns it to the compressor via capillary
tubes. Also functions as reservoir for holding excess oil.
E. Solenoid valve (for pressure equalization) Y4S
Balances high and low pressure when stopped.
F. Solenoid valve (for liquid injection) Y2S,Y3S
Controls liquid injection to prevent overheating.
G. Solenoid valve (for oil discharge control) Y5S
Discharges excess oil to other outdoor units during oil equalization operation.
H. High pressure switches S1HP, S2HP
Switches trip when preset pressure exceeds 27.5±0.5K, thus stopping operation.
I. High pressure switch S3HP
Switch trips when operation pressure exceeds 24.0K and switch on at 17.0K, thus control high pressure.
J. Low pressure switch S1PL
Switches trip when the suction pressure is lower than 0±0.3K.
