Copeland demand cooling module wiring diagram. However, for applications requiring Demand Cooling, the Demand Cooling module should have primary control of the temperature protection. Point (A) shows that with 65°F return gas and 110° 5. If the wiring condensing temperature. 5 Demand Cooling wiring diagram Wiring diagram Legend A1 . Room thermostat B11 Application guide for Copeland Discus, K, L & S-Series semi-hermetic compressors. Copeland Discus Demand Cooling. Figure 11 - Digital Compressor Controller Wiring Diagram Figure 12 – Demand Cooling Module Wiring Diagram © 2015 Emerson Climate Technologies, Inc. View and Download Emerson Copeland Discus 4D X Series application engineering bulletin online. If a critical temperature is reached, the driver energizes a long life injection valve which meters a controlled amount of saturated refrigerant into the compressor suction cavity to cool the suction gas. For more information on Copeland Demand Cooling, refer to AE4-1287: ”Copeland DiscusTM Compressors with Demand CoolingTM System”. However, for applications using Demand Cooling, the Demand Cooling module should have primary control of the temperature protection. When Demand Cooling is required the module energizes the Demand Cooling Injection Valve (hereafter called “injection valve”) and the injection valve injects saturated refrigerant into the compressor suction cavity until the discharge temperature drops to an acceptable level. Copeland developed and released the Demand Cooling system for Copeland Discus compressors to provide a solution for applications with high discharge temperatures such as the R-22 low temperature refrigeration applications. To ensure the Demand Cooling system functions appropriately, jumper the T1 and T2 inputs on the Digital Compressor Controller, with a 5kOhm, 1 Watt resistor. CoreSense module A4 . circuit wiring to be sure the module is wired to stop allowable evaporating temperatures using a given the compressor when the module trips. , at- tached to motor-compressors or condensing units should be read and filed for future refer- ence. Sensor module A5 . . Compressor terminal box A6 . Compressors with Demand Cooling System. Wiring of CoreSense Protection with Copeland Demand Cooling is shown in Figure 6. Wiring diagrams, instruction bulletins, etc. Also for: Copeland discus 4d n series, Copeland discus 6d x series, Copeland discus 6d However, for applications requiring Demand Cooling, the Demand Cooling module should have primary control of the temperature protection. To ensure the Demand Cooling system functions appropriately, jumper the T1 and T2 inputs on the Copeland Digital Compressor Controller, with a 5kOhm, 1 Watt resistor. The Normally Closed (NC) contact of the alarm relay (L to M) should be wired in the compressor contactor control circuit so that opening this contact removes the compressor from the line and removes power to the Demand Cooling Module. Includes information on installation, operation, maintenance, and troubleshooting. The Demand Cooling driver uses the signal of a discharge head temperature sensor to monitor discharge gas temperature. The Demand Cooling system uses the discharge temperature sensor (PT1000) pre-installed at the factory and connected to the Copeland Compressor Electronics module, but the discharge temperature sensor position has to be changed to the other hole of the cylinder head where it is already located. Copeland Discus 4D X Series air compressor pdf manual download. Make the proper refrigerant connections and charge the unit with the refrigerant to be used. One should be removed so that the nameplate indicates the refrigerant used. 5 Installation of Demand Cooling on 4M* Stream compressors NOTE: An additional fan is needed only for application of Demand Cooling with R22. View and Download Emerson AE4-1287 R7 manual online. Without Demand Cooling, these high temperatures typically resulted in overheating of the lubricant leading Ae1287 copeland discus-compressors-with-demand-cooling-system - Download as a PDF or view online for free Demand Cooling – The Copeland Discus compressor with CoreSense Diagnostics is equipped with Demand Cooling capability, and as such may be used as an R407A / R407C low temperature compressor.
