Adjusts its own rotational speed based on the actual requirement of the
system to implement capacity control.
Maintains a proper oil temperature in the compressor when the compressor
is in standby status, ensuring the reliability during compressor startup.
Detects a compressor's exhaust gas temperature for compressor control
and protection.
Protects a compressor by sending feedback signal to stop the system when
the compressor's discharge pressure exceeds the operating value of
high-pressure circuit breaker.
Separates the gas and oil in the system to ensure compressor reliability.
Prevents high-pressure gas from entering the compressor and fast balances
the suction pressure and discharge pressure in a compressor.
Detects the high pressure value in the system in real time mode for
compressor protection and other control functions.
Used for the switching between the cooling and heating functions of system
IDU.
