Compressor

COMPRESSOR




As two scrolls (one movable and other fixed) are engaged, a crescent chamber is formed between multiple contact points. The movable scroll cannot rotate on its own axis but orbits instead, so the operating chamber moves inwards while its capacity is reduced. Intake, compression and discharge take place simultaneously at multiple operation chambers, and compressed refrigerant is sent from the discharge hole at the center to the oil separator and then separated in to refrigerant gas and oil before it is output from the discharge port.

PRESSURE RELIEF VALVE




This valve opens if the pressure of the high-pressure refrigerant gas rises to a dangerously high level to release part of refrigerant into the atmosphere, thus protecting the compressor. The valve is designed to limit the amount of released gas to the necessary minimum.
- Valve opening pressure: above 3.43 MPa (35.0 kgf/sq.cm)
- Valve closing pressure: above 2.75 MPa (28.1 kgf/sq.cm)
- Valve wide open pressure: below 4.14 MPa (42.2 kgf/sq.cm)
