Features
Danfoss Intermediate Discharge Valves (IDVs)
are located close to the discharge side of the
compressor. They reduce excessive compression
of refrigerant under part-load conditions while
maintaining the same cooling capacity. The IDVs
open when discharge pressure falls below the
built-in optimization point. They adapt the effort
of the motor to the varying load and pressure
conditions in the system, thus reducing the effort
of the motor and its electrical consumption
and improving the system’s seasonal energy
efficiency.
How do IDVs work?
Intermediate discharge
valves for better efficiency
at low pressure-ratio
Optimized scrolls for
better part load efficiency
New distributed IPM
motor lead to higher
power factor
High speed oil circulation
minimized by an oil return
tube
Linear control oil pump
POE 46 lubricant ensures better
lubrication and efficiency
New designed oil cup to
minimize oil stirring loss under
high liquid level
EMC (Electro-Magnetic
Compatibility) bracket
provided allows for
grounding termination
of shielded wire-harness,
which reduces EMC
emissions between drive
and compressor
