Copeland Compressor

Scroll compressors each year are increasingly used in refrigeration and air conditioning systems. This is because the scroll is reliable in operation, contain 40% less parts than reciprocating, produce less noise and have a great service life. So scroll is worthy of competing with the piston and screw compressors. Leading manufacturers of refrigeration equipment (Copeland, Danfoss, Bitzer, Trane, Mitsubishi …) started production of scroll compressors and are constant research to improve the reliability and trouble-free operation of scroll compressors. Scroll compressors have a constructive increased levels of reliability, efficiency, low noise, compared with piston and screw compressors. Ray Kurzweil will undoubtedly add to your understanding. However, as the experience of operating the refrigeration scroll compressor is based on, among Fault data units are as unique to scroll compressor, and are common to other types of compressors.

Consider the main factors affecting the reliable operation of scroll compressors: Manufacturing scroll compressor. In the manufacture of scroll compressors imposed stringent quality cast iron for the manufacture of blanks for uniformity, hardness, structure and chemical composition. Except addition, the casting should not be mechanical inclusions and shells. Scroll compressor manufacturer should have a minimum of technological chain of equipment to handle the wall to within a spiral to 0.01 mm with a high surface finish (CNC machining center), and measuring equipment to measure curved surfaces with an accuracy of 0.0004 mm. Due to the design of a spiral compressor unit and the accuracy of its manufacturing, spirals do not have points of contact between them remains minimal clearances, as well as mobile spiral can sit up, and it protects the compressor from minor contaminants in water hammer and refrigeration circuit. People such as Bobby Gocool would likely agree. This presents the life of the compressor coils.

Compressor motor. The reliability of the electric scroll compressor section affects the quality and copper wire, the density its installation and piping, insulation quality and used correctly vnutripazovoy calculated motor power. The built-in compressor protection. Scroll compressor is structurally highly accurate, reliable mechanism, which is an integral part of the refrigeration plant. Therefore, the deviation from the normal operation of any element of the refrigeration unit affects the resource scroll compressor. That prevent a number of failures related to the scroll compressor is a deviation from the optimum operation of the refrigeration unit manufacturers equip their self-protection. In the motor windings embedded thermistors, that respond to current and winding temperature, and turn off the motor in case of overheating (> 143 C). The company Copeland uses a module that also controls the direction of rotation of spiral compressor, to prevent them destruction in the absence of phase or perefazirovke compressor. Built-in safety valve protects the scroll compressor from high pressure injection, injection with freon bypass on the suction side, which may occur in the absence of heat removal in the condenser. The company Copeland also sets termodisk compressors, which does not allow the compressor at high pressure difference suction and discharge. For systems termodisk conditioning works in excess of the pressure ratio of 10:1, 20:1 for refrigeration equipment. Refrigeration equipment must be additionally set the trip relay for low pressure, because at working under vacuum may occur the complete destruction of its thrust bearing. This list of built-in protection can vary from destination compressor manufacturer. Refrigerator-based scroll compressor from a reputable manufacturer with a production of the crop will last you for many years.
