DSH series scroll compressor benefit from
an improved design to achieve the highest
efficiency and increased life time.
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?
DSH090-105-120-140-161-184
DSH240-295-381-485
Overview
Intermediate discharge valves (IDVs)
increase seasonal efficiency
Heat shield lowers the heat transfer
between discharge and suction gas
and the acoustic level
Internal Non Return Valve (INRV)
prevents excessive leak rate from
high pressure side
Lead free polymer bearings improve
behavior under poor lubrication
conditions
Integrated discharge gas
temperature protection (DGT)
Patented motor cap for optimal
motor cooling and higher
resistance to liquid slugging
Organ pipe master oil circulation
in manifold configuration.
Patented gas path flow with
gas intake design induce higher
resistance to liquid slugging
