Analysis of main characteristics of Feixun series Copeland compressors

Analysis of main characteristics of Feixun series Copeland compressors The main features of Copeland Compressor Feixun series are as follows: 　　 1. The main features of Feixun compressor: ① maintainability is stronger; ② all parts can be disassembled and replaced; ③ main components are installed along the axis. 　　 2. Higher reliability: more than 100 million flexible vortex designs and applications worldwide have a higher tolerance for liquids and impurities. 　　 3. Wider operating range: In the application of integrated jet enthalpy increasing technology R22, it can reach -40 degrees evaporation temperature without the need of cylinder head fan. 　　 4. High efficiency and higher: Economizer circulation is designed for high-efficiency scrolls for refrigeration applications. 　　 5. More intelligent: ①Coresense diagnosis module; ②Quick and accurate compressor monitoring and diagnosis. 　　 6. More applicable refrigerants: applicable to new refrigerants (R404A), Jindian refrigerant produced by Nanjing Jinling Refrigeration fully meets its needs. 　　 7. Economizer and discharge temperature: Feixun Compressor integrates a set of economizers to improve the working efficiency and reliability of the compressor when operating at low temperature. The jet enthalpy increase is achieved through the economizer cycle, which further increases the supercooling of the main line liquid and cools the oil temperature of the compressor. The temperature of the liquid in the main circuit passing through the economizer should be lower than the ambient temperature, so the liquid pipeline flowing from the economizer to the evaporator must be insulated. The increase in supercooling will increase the night supply capacity of the expansion valve. Therefore, the user must refer to the liquid pipe temperature data provided by the compressor manufacturer to select the appropriate expansion valve for the refrigeration system. Refer to the liquid pipe temperature in the performance data. 　　 8. Pumping cycle: Pumping cycle has been widely used in refrigeration system. The Feixun compressor has a stronger liquid tolerance, so there is no need to perform an evacuation cycle every time the Thermostat system stops. Performing an evacuation cycle before the start of defrosting can help shorten the defrost time. The Feixun compressor itself has a built-in low-leakage exhaust check valve with a spring, so there is no need to configure an additional check valve on the exhaust pipe. When the pumping cycle ends, the compressor stops, and a large volume of high-pressure gas is stored in the compressor discharge chamber. This part of refrigerant will quickly leak back to the bottom pressure side after shutdown and cause the low pressure to rise, and the low pressure controller will reset. The control system should avoid starting the compressor in this situation. It should only allow the compressor to start when the thermostat is reset.
