13 Copeland Discus Compressors with CoreSense Protection Enhanced Protection & Features Additional motor protection Power interrupt protection Welded contactor protection Discharge temp protection Compressor proofing Simplified commissioning Comp display status, current, DLT Diagnostic/troubleshooting aid Communications open protocol Software upgradeable 24V control circuit Operational savings and less downtime for commercial refrigeration users REDUCE MAINTENANCE COSTS Copeland Discus semi-hermetic compressors have been the standard in the refrigeration industry for years, offering the most energy-efficient, reliable performance available in heavyduty applications. Now this compressor offering has made another major advancement with CoreSenseTM Protection on board, a breakthrough technology for commercial refrigeration systems. By using the Copeland Discus compressor as a sensor, CoreSense Protection monitors and interprets system and electrical information within the compressor, shutting it down before damage occurs. Copeland Discus with Core Sense Protection alerts technicians to the most serious faults first so they can accurately and rapidly correct problems and prevent catastrophic compressor failures that could suddenly generate product spoilage. 13

15 HEAD PRESSURE CONTROL The design of air conditioning and refrigeration systems utilizing an air-cooled condenser involves two main problems, high and low ambient temperatures. If the air-cooled condenser is properly sized, it will operate satisfactorily during extremely high ambient temperatures. However, since most units will be required to operate at ambient temperatures below their design dry bulb temperature during most of the year, the solution to low ambient operation is more complex. RefPlus has two methods of head pressure control to solve these system problems one adjustable and one non-adjustable. Each method utilizes two valves designed specifically for this type of application. A drop in the condensing pressure often occurs on aircooled systems as a result of low ambient conditions encountered during fall-winter-spring operation. FIXED PRESSURE FLOODING VALVES CONDENSER Without good head pressure control during low ambient operation, the system can experience both running cycle and off-cycle problems. Two running cycle problems are of prime concern: SUBCOOLER LIQUID 1. Since the pressure differential across the thermostatic expansion valve port affects the rate of refrigerant flow, low head pressure generally causes insufficient refrigerant to be fed to the evaporator. SUCTION ADJUSTABLE PRESSURE FLOODING VALVES CONDENSER 2. Any system using hot gas for defrost or compressor capacity control must have a normal head pressure to operate properly. In either case, failure to have sufficient head pressure will result in low suction pressure and/or iced evaporator coils. SUBCOOLER LIQUID SUCTION The primary off-cycle problem is the possible inability to get the system on-line if the refrigerant has migrated to the condenser. The evaporator pressure may not build up to the cut-in point of the low pressure control and the compressor will not start even though refrigeration is required. Even if the evaporator pressure builds up to the cut-in setting, insufficient flow through the TEV will cause a low suction pressure which results in compressor cycling. The RefPlus Head Pressure Control s purpose is to hold back enough of the condensed liquid refrigerant so that some of the condenser surface is rendered inactive. This reduction of active condensing surface results in a rise in condensing pressure and sufficient liquid line pressure for normal system operation. RefPlus also offers non-flood and floating head pressure systems. For non-flood and floating head pressure systems, use the adjustable flooding valves set at 70 F (21 C) condensing combined with our new liquid sub-cooling fan cycling and speed control. 15

16 SPECIFICATIONS CASINGS: Air-cooled condensing unit bases, condenser fan section and electrical boxes are heavy-gauge galvanized steel (G90) with plated or stainless steel hardware. Model OCS cabinets are painted galvanized steel, and OVS models are heavy-gauge galvanized steel (G90) for corrosionfree assembly. Cabinets are provided with hinged access door with holder. OVS condenser includes side access panels for easy coil inspection and cleaning. CONDENSER COILS are manufactured with seamless, deoxidized, heavy wall, and smooth copper tubes. They are mechanically expanded in self-spaced, full-collared aluminum corrugated plate fins for permanent bond and maximum heat transfer. Connections and bends are brazed with a high temperature-brazing alloy. Coils are provided with an integrated, true sub-cooling circuit. Coils are factory leak tested at 400 psig using -40 F/-40 C dew point dry air. Model OVS: All tube sheets are provided with oversized holes, and coils are supported in sliding tracks for friction-free assembly and maximum reliability. FAN GUARDS AND MOTOR MOUNTS are welded wire construction for full protection from moving parts. Baked-on powder epoxy coating provides corrosion protection. FANS are aluminum blades riveted to a steel hub. They are statically and dynamically balanced for smooth and vibration-free operation. Model ICS and OCS 008 to 017 use 16 fans and 020 to 220 use 20 fans. OVS medium uses 20 fans. OVS large uses 30 fans. FAN MOTORS are low speed, permanently lubricated sealed ball bearings and inherent thermal protection for long life and dependable service. Model ICS, OCS, OVS medium are line voltage single phase. Model OVS large are line voltage three phases. WIRING: Fan motors are wired using flexible cord, Type SOW 90 C #16 AWG and are secured with certified liquid-tight connectors (OVS). Compressors and fan motors (ICS and OCS) and controls are wired using water and oil resistant wire, Type TEW 105 C protected by plastic or metallic conduit attached with certified connectors. ELECTRICAL BOXES are located on the front (ICS and OCS) or side (OVS) of the unit for easy access and service. They are weather protected and are manufactured of heavy-gauge galvanized steel and assembled with plated or stainless steel hardware for corrosion protection. CONTROL PANELS are complete with terminal blocks, control transformer, control circuit fuses, compressor and fan contactors (multi fan units), liquid sensing fan cycling thermostats, fix high and adjustable low pressure control, and a pump-down switch. The wires are numbered, color-coded and conveniently routed in wiring ducts. All terminal blocks are identified and match the wiring diagram. COMPRESSORS are air or suction cooled, refrigeration duty, accessible semi-hermetic. They are supplied with suction and discharge valves, suction strainer, oil filter, oil pump on model 3PH and larger, solid state or line break thermal protection, crankcase heater, mineral oil for HCFC refrigerant and Polyol Ester oil with HFC refrigerant. RECEIVERS (6" dia. and smaller) are UL/CSA certified and are supplied with a fusible plug. Receivers (6 5/8" dia. and larger) are CRN or ASME "U" stamped and are supplied with relief valves. All receivers have inlet and outlet back-seated Rotalock valves. For low ambient operation, RefPlus offers a factory installed insulation and heating option. REFRIGERATION FLOODING VALVES are factory installed. They are either fixed or adjustable. REFRIGERATION COPPER TUBES are ASTM certified and are factory bent using a programmable CNC tube bender. They are manufactured with the minimum number of fittings and brazed joints to reduce the risk of leaks. FACTORY TESTED: All RefPlus units are electrically tested. A Dielectric Voltage Withstand Strength Test is done on all units. The compressors are energized, and the operating sequence and all controls on each unit are factory tested. Refrigeration piping is leak tested and the system is pressurized and sealed with -40 F/-40 C dew point nitrogen.
