11. Digital Compressor
Is variable the compressor capacity from 10% to 100% by using the Loading/Unloading cycle.
12. Fixed
Fixing capability compressor which ON/OFF by the load.
13. Compressor (1, 2) Accumulator
Protect the compressor by preventing the liquid back to the compressor.
14. PWM Value
This is the valve which installs to the upper part of the Digital Scroll compressor and the low pressure pipe to use for Digital
Scroll compressor capacity variableness. When the power is permitted to the valve, the Digital Scroll compressor keeps the
Unloading status.
15. High Pressure Sensor
Use to protect the system or control the compressor capacity during heating operation by measuring the high pressure.
16. Low Pressure Sensor
Use to protect the system or control the compressor capacity during cooling operation by measuring the low pressure.
17. High Pressure Switch
If the high pressure is more than the setting value, stop the system to protect.
18. Main EEV (Sub EEV)
This is the expansion side being used during heating operation, control the refrigerant flux.
19. Liquid EEV
Use to prevent the compressor overheating and control the degree of the overcooling during cooling operation.
10. Hot Gas Valve
Use to prevent sudden dropping to the low pressure and convert the inside of the compressor Shell to the high pressure
during equal oil operation.
11. Liquid Tube Valve
Prevent the inflow of the refrigerant from the outdoor unit when the outdoor unit is stopped.
12. Oil Valve 1
Control the oil movement between outdoor units.
13. Oil Valve 2, 3
Control the oil movement between compressors.
14. Discharge Sensor
Use to protect and control the compressor by measuring the temperature of the compressor outlet.
15. Cond Out Sensor
Use to decide the amount of the refrigerant during cooling operation and to decide the start or cancellation of defrost operation
during heating operation.
