  1. LG Electronics Inc. LGEHQ CAC Team Toshiba S-MMS vs LG MULTI V Plus II

  2. 1. Compressor comparison Inverter Scroll compressor is the best solution for a commercial building.

  3. 2. Power consumption comparison ■ Design condition of HCL COMNET SYSTEMS & SERVICES LTD - Total capacity of system : 560Hp (48Hp * 11EA / 32Hp * 1EA) ■ Operation condition of A/C units - 24hours / day, 30days / month, 12month / year - Electrical charge : 6Rs / kWh

  4. 3. Performance comparison under the hot temp. Inverter Scroll compressor has high performance under the condition of hot temp. 135 52.55 130.37 49.67 45.38 125.60 42.00 <Cooling Capacity> <Power consumption>

  5. 4. Compressor comparison (Efficiency) Rotary compressor is weak for liquid compressing and has 92% cooling and heating efficiency compared to scroll compressor. Capacity (kW) Toshiba S-MMS MULTI V PLUS II 24.0 MULTI V PLUS II 25 Rotary type Scroll type Type 20 19.4 16.3 ※Based on 1 inverter comp. 15 Structure 13.1 Frequency (Hz) 60 90 120 ※Reference from each companies’ compressor catalogue MULTI V PLUS II Less Liquid handling Convenient for handling large capacity Feature Volumetric Efficiency 92% 100% (Base) [Efficiency comparison for compressor type (reference from air-conditioning technology thesis)] Origin of Development Toshiba (Japan) LG (Korea)

  6. 5. Design limit comparison LG MULTI V PLUS II is excellent for maximum pipe length ■ LG MULTI V PLUS II system has a plate type sub-cooling HEX • Increased sub-cooling by plate-type heat exchanger • Enable to be long piping length and level difference • More powerful Cooling operation Plate typeSC
