Digital Compressor Technology, Design and Applications Copeland Scroll Digital™,Discus Digital™ and Variable Speed Compressors
Why Modulation?
Precise Load Matching – When supply and demand are largely different
Better Seasonal Efficiency – Reduced Power Consumption & Running Costs – Lower CO2 Emission – Compliance to Minimum Efficiency Regulation

As Zones get Satisfied in A/C, cold air is re-circulated back to the unit causing Low Suction Pressure and
Control Issues
Digital Benefit in Rooftop Applications Tight Air Temperature Control
– Comfort Improved Humidity Control
– Comfort Tight Supply Air Flow Control
– Increased Efficiency – Possibilities to reduce air flow to Minimum
Reliability Simple No Oil Return issue No risk of resonance associated as Inverter

Low Condensing Considerations • Increased Capacity
– Digital Modulation Prevents Excessive Cycling – Electronic Expansion Valve Ensures Precision
Superheat Control Across Entire Capacity Range
• Low Pressure Ratio – Copeland Compressors Approved To Operate At:
• 50°F Min. Cond. Temp. For Medium Temp. Applications*
• 40°F Cond. Temp. For Low Temp. Applications
– Electronic Expansion Valve Operation Not Affected By Low Pressure Differentials
• Flash Gas In Liquid Line
– Adequately Size Expansion Valve To Digest Flash Gas Or Design To Ensure Liquid At Expansion Valve

Low Pressure Drop System Benefits
• Reduce Energy Usage • Precise Temperature Control • Precise Humidity Control • Reduced Defrost Time • Increased System Capacity • Reduce Refrigerant Charge • Reduced Leaks • Reduced Downtime • Complete Capacity Modulation • Improves Profitability • Improved Product Quality • Prevents Floodback with EX when Evaporator Fan Motors burns out
Simplified Efficient Solution
Cold Storage Warehouse takes Advantage of low Ambient Temperatures
Customer Pain • High Energy Bills (108HP of Equipment 4 x 27HP Units) X 2 • 100,000 lb of Turkeys, pull down 4°C down to -25°C. • 72 hours Required to Pull and Hold • Production maxed out
Execution • New Equipment with Copeland Discus III (575V) 27 HP LT. • New Electronic EX Valve on each Evaporator • VFD Condenser fan control down to 60°F SCT Minimum (old system was set for 110°F SCT)
End User Benefits • Calculated Energy Savings $240,000 / year
• Start up Occurred Spring 2012
• Pull Down Time 48 hours ( 33% faster) • Increased Capacity by 33% • Two Months After Opening, Power issue (208V) to the Facility took out all Evaporator Fan Motors….and Rack Cycled off on Low
Pressure rather than Liquid Slugging Compressors • End User is Thrilled with Increased Profitability
