These two Copeland ZR series compressors adopt patented flexible scroll technology, achieving an energy efficiency that is 12% higher than advanced piston compressors in the market. The COP value can reach 3.15-3.25, and the EER value reaches 11.4, demonstrating significant energy-saving effects.
Additionally, with fewer moving parts and the use of axial and radial flexible designs, they offer unprecedented resistance to liquid slugging and tolerance for impurities. The built-in motor short-circuit protection effectively safeguards the motor, ensuring extremely high reliability.
Moreover, the noise level is more than 5 decibels lower than that of piston compressors, resulting in smooth and quiet operation. The unique unloaded startup design eliminates the need for a start capacitor and relay during single-phase compressor startup, simplifying the system design.
