Semi-hermetic Reciprocating Compressors

Features and Benefits

x Small physical size and weight for comparable displacement and capacity

x Universal

oOne compressor version for all temperature ranges using R404A, R507,

and R22

x Smooth and Quiet Operation can be Attributed to:

oShort stroke operation

oMultiple cylinders positioned to avoid harmonic frequencies

oBalanced drive systems

oCylinder heads with cast in muffler

oPrecision machining

x Unloaders

o1 step (50%) capacity control on 4-cylinder models

o2 steps (33%, 66%) capacity control on 6-cylinder models

x Motors

oDual voltage on models above 1480 CFH

oMotor efficiency 90% or greater

oElectronic motor protection with embedded thermisters to sense motor

winding temperatures

x Oil System – IR4C models, smaller 4 cylinder compressors

oEnhanced centrifugal lubrication system

oFront main bearing is located in cavity on front bearing plate and is

submersed in oil

oFills front bearing cavity with oil in a fraction of a second

oWhen oil is diluted with refrigerant, separation of oil and refrigerant takes

place as the oil is “slung” against the front bearing cover

oOil travels down internal passages in the crankshaft, driven by centrifugal

force. This lubricates the connecting rod bearings and motor bearings

oHydrodynamic lubrication provides enough oil and pressure to lubricate

the bearings without floating the bearing in oil

oPiston pin bearings are splash lubricated by the connecting rod

oOil carry over is minimized since high-pressure oil is not forced into the

motor cavity

oEfficiency is increased since no power is required to drive an oil pump

Features and Benefits

3

x Teflon Impregnated Bearings

oBearing composition is metal and PTFE (Teflon)

oAllows for safe operation during marginal lubrication periods

x Eccentric Rods

oAluminum alloy

oHigh quality and low tolerances can be maintained due to one-piece

construction

oLow bearing loading & high velocities, increase the running capability of

bearings under boundary lubrication conditions

x Crankshaft

oHigh quality cast iron

oA gas nitration process hardens all crankshafts

oHardening provides a better bearing surface with excellent wear resistance

x Crankcase Design

oAllows for large oil volume in a compact housing

oRefrigerant flow paths and oil system reduce oil carry-over and reduce

liquid slugging potential during starting conditions

oSpecial gray cast iron provides durability and excellent heat transfer

characteristics

oSingle casting requires only motor end bell cover and front bearing cover

x Oil Pump vs. Enhanced Centrifugal Lubrication

oPower consumption is approximately 0.5% less with the enhanced

centrifugal system

oOil carry-over rate is lower with the enhanced centrifugal system

x Cast in Muffler

oReduces discharge gas pulsations without external muffler or bulky

cylinder heads

oPulsation reduction

62% at Low temperatures

70% at Medium temperatures

88% at A/C temperatures

x Piston Design

oSpecial aluminum alloy

oSimilar to automotive designs

Adaptability at varying temperature condition

Full sealing capability at varying temperature conditions

Features and Benefits

4

x Piston Rings

o 4 & 6 cylinder models have two rings, a chrome plated compression ring

and an oil ring

o Chrome plated rings provide excellent running durability under boundary

lubrication conditions

oPiston rings are sealed by gas pressure balancing the ring tension to the

proper value

oProvides excellent sealing under various pressure and speed conditions

x Cylinder Design

oCrosshatch honing i.e. "Plateau honing"

oCross-hatching allows for higher tolerance operation with marginal

lubrication

oCross-hatching grooves help resist wear by retaining oil in the cylinder,

and therefore increases compressor life

x Valves Plates

oSpring steel reed valves

oValve reeds are matched to compressor design to optimize performance

and efficiency

oFlow passages optimized for minimal pressure drop

oHigh volumetric efficiencies due to minimal re-expansion volume
