70 HP Refrigeration Chiller D8SK1-7000-BXW-BM844 Semi Hermetic Compressor
Speciafication:
Compressors in the higher capacity range need some form of capacity
control to accommodate varying
refrigeration load. The capacity control kit supplied by DWM
Copeland will reduce the refrigeration capacity along
with a similar proportional reduction in Power Input. This ensures
optimum performance even in part load.
Capacity control is also required when the condensing pressure
falls with a drop in ambient air temperature.
The compressor suction condition, refrigerant volume and mass flow
rate will remain unchanged.
Methods of Capacity Control
There are many methods of capacity control for Semi-Hermetic
compressors but DWM Copeland use the “Blocked
Suction method” and for the D3D Over Re-expansion method known as
Moduload.
Note: Oil circulation in systems with capacity control is more
critical.
The 4S, 6S & 8S compressors have an internal capacity control,
they work on the principle of blocking the suction
gas passage to two or more cylinders. They require the use of a
special cylinder head and a control valve with
solenoid coil. These items may be ordered installed at the factory
or in a kit form for later installation.
The suction port of the valve plate will be closed by a control
piston (blocked suction). To prevent transport damage
the solenoid valve is supplied loose and the cylinder head is
fitted with a shipping plate, therefore the shipping plate
with gasket must be removed and the solenoid valve with new gasket
mounted. Do not put the compressor into
operation with the shipping plate this could result in erratic
operation of the control piston and inadequate cooling
capacity.
