Features

• Wide Compressor Operation Range 12~160Hz

  

  Wide range operating Hz control of compressor is best fit for variously changing heat load
  - World best compressor speed 160 Hz : rapid response capability
  - Down to 12 Hz : optimized for even small load operation (efficiency increases / Improved comfort)
  

• Double Vapor Injection

  

  - Maximize heating capacity via two-stage compression
  - Provide powerful heating in low temperature conditions
  - Improve energy efficiency and heating performance
  

• Design Improvement for High Efficiency

  

  High volume ratio scroll profile with large discharge by-pass port
  : Optimization for wide operating pressure ratio
  

• Direct Oil Injection

  

  - Eliminate suction refrigerant gas heat loss through direct oil injection into compression chamber during compression process. (efficiency increases)
  - Even at low-speed operation, can ensure a sufficient oil amount inside compressor. (12 Hz)
  - Reliability increase due to the oil discharge reduction in high speed. (160 Hz)
  

• Motor Efficiency

  

  - Improved efficiency at low speed by concentration coil.
  - At low load conditions, efficiency by reducing the copper coil loss was improved compared to existing.
  - Enable high efficiency through use of 12 Nd magnets.
  - Noise and vibration reduction than distribution coil.
  

• HiPOR TM

  

  Innovative LG’s HiPORTM technology contrasting conventional oil return system
  [ 2010, Purdue Conference, “Development of High-Side Scroll Compressor with Novel Oil Return Mechanism” ]
  

• Oil level sensor

  

  Oil return operation if necessary
   Reducing the number of oil return operation innovatively
