Table of Contents Technical Information Date of last update: 0608 Ref: D7. 1 General information about Copeland™ Stream Digital semi-hermetic compressors These guidelines cover Copeland™ Stream Digital semi-hermetic compressors. 2. SEMI-HERMETIC COMPRESSORS OIL PRESSURE DIFFERENTIAL SWITCH. Jan 11, 2010 · In this case, it would be 80 psi – 20 psi = 60 psi net oil pressure. Compressor packs are available in 3,4 & 5 compressors options with maximum Copeland Stream Compressor Designed to Deliver Best-in-Class Performance Stream Compressor Line-Up 50 70 90 100 110 Stream 6 Cylinder Stream 4 Cylinder 60 80 120 130 140 150 160 Copeland™ Stream With CoreSense™ Diagnostics, Semi-Hermetic Reciprocating Compressors for HFC / HFO Blends Features and Benefits • 3Range of 16 models from 62 to OMB / OMC SERIES OIL MANAGEMENT CONTROL The OMB/C prevents compressor burnout and system downtime by maintaining a proper compressor crankcase oil level. ) Copeland semi-hermetic compressors Capacity control for Discus and "S" series 1 Compressor capacity modulation for air-conditioning & refrigeration systems 1. The Stream Digital series of 4M*D and 6M*D models ranges from 13 hp to 50 hp. Internal channels drilled through the Copeland Stream semi-hermetic compressors Copeland Compressor Electronics the module will trip the compressor and a "low oil pressure lockout" will be reported Compressors DLHA, Discus and 2 stages are lubricated by an internal oil pump and are equipped with a compact electronic oil pressure switch: OPS1 Other DK and DL: lubrication is achieved by a splasher with the mineral oil compressors while the "ester" oil models incorporate an internal oil pump that does not need an oil pressure safety switch. This means the oil pump is actually putting 60 psi of pressure into the oil when delivering it into the crankshaft’s drilled passages. The switch must be correctly calibrated and tamper proof. Net oil pressure can be read by connecting two pressure gauges to the compressor and comparing the readings. The semi-hermetic reciprocating compressor family consists of different ranges: The K- and L- series from 0. It is not intended to replace the system expertise available from system manufacturers. 6 Infinite capacity control Oil circulation 3 Lubricants 4 Integration into the refrigeration circuit 2021/MEA/70. com installation, starting, operation and maintenance of semi-hermetic compressors. Copeland has worked closely with several The oil pump integrates the electronic switch for integrating oil pressure safety functionality. Note that Stream 4M* and 6M* compressors are covered in a different manual see – AGL_Stream_ST_A2L_A1_4M_6M_EN "Copeland™ Stream Semi-Hermetic Compressors". Oil pressure safety controls are supplied as standard on each compressor on all Copeland® tandem condensing units, and are a requirement of the Copeland warranty covering these compressors. 1 Capacity control Compressors in the higher capacity range need some form of capacity control to accommodate varying refrigeration load. They can be an effective method of accurately matching compressor capacity to load requirements. These differences require different considerations for oil management when using Copeland Scroll refrigeration compressors in parallel rack applications. The Stream series of 4M* and 6M* models ranges from 62 to 153 m³/h displacement. Oil Pressure Normal oil pressure is between 1. Model Nominal horsepower Copeland semi-hermetic compressors Use of inverters with K/L, Discus and "S" series Introduction Inverters are used to vary the speed of motors and in thereby control the capacity of a compressor. The compressor line is characterized by a design operating pressure of 1740 psig (120 bar). These application guidelines cover Copeland Stream semi-hermetic compressors. What came out of this endeavor is the newly-designed Copeland Scroll Fusion compressor which combines Emerson’s revolutionary scroll technology along with the serviceability of a traditional semi-hermetic compressor. It is directly screwed into the pump housing. 1 Design features 2. Variables that affect the net oil pressure include: Bearing clearance; Viscosity of the oil; Temperature of the oil; and; Compressor size. DWM COPELAND OPS2 switch pdf manual download.
