  1. 1. BITZER Scroll Compressor Solutions BITZER KÜHLMASCHINENBAU GMBH March, 2018
  2. 2. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // Agenda Challenges in the European Chiller Market / EcoDesign and F-Gas regulations Possible Solutions / ORBIT+ / A2L Refrigerants
  3. 3. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // Challenges EU F-Gas Regulation 517/2014 GWP-average values according to regulation steps (estimate) Assumptions: • Refrigerant amount emitted = 2008-2011 in kg (including all service use) • No drastical leakage reduction • No major market increase • No major technology change R32, R452B R454B R410A
  4. 4. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // Platform / ORBIT+ with LSPM motor  increases seasonal efficiency by ~7%(SEER/IPLV) without changes on the chiller plattform / A2L refrigerants  R452B, R454B and R32 available for all applications
  5. 5. BITZER // Convegno CSG // Scroll Compressors // MCE18 Line Start Permanent Magnet “LSPM“ Motor BITZER Scroll Compressors // ORBIT+ GSD6 GSD8 ORBIT+ Series Standard Series GSU6 GSU8
  6. 6. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // ORBIT+ Implementation of high-efficient ORBIT+ Scroll compressors / Line Start Permanent Magnet Motor (LSPM)  Significantly increased annual energy efficiency  Permanent Magnet Motor can be used DOL  Combines efficiency of a synchronous motor with robustness and easy use of an asynchronous (AS) motor  Lower current than standard AS motors  Potential for smaller electric contactors  Same dimensions, electrical connections as standard compressor
  7. 7. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // ORBIT+ ORBIT+ with A2L Refrigerants BITZER solution answering to ECO design directive and F-GAS regulation / Cooling Capacity  Compensation of cooling capacity losses with the LSPM motor / SEER Efficiency  LSPM motor + R454B = significant increase of SEER 2.8% 0.8% GSD60120 GSU60120 GSU60120 R410A R410A R454B 4.16 4.48 4.57 GSD60120 GSD60120 LSPM GSDU60120 LSPM R454B SEER (EN14825) 7.7% 9.9% GSD60120 GSU60120 GSU60120 R410A R410A R454B
  8. 8. BITZER // Convegno CSG // Scroll Compressors // MCE18 BITZER Scroll Compressors // ORBIT+ / ORBIT+ compressors approved for R410A and alternative low-GWP A2L refrigerants (R454B, R452B, R32), with CE marking  PED approval for Fluid Group 1 and Fluid group 2 refrigerants / Performance tests with GSU6/GSU8 and R410A/R454B/R452B  Performance coefficients available  Current status on R410A:  5-8% increase in SEER efficiency, 3-5% increase in cooling capacity / R454B (XL41, GWP: 466, A2L, Temp. glide ~1.5K), preferred in EU  Average 3% higher COP and 3% less cooling capacity than R410A  R32 (GWP: 675, A2L) shows much higher DGT and lower efficiency
