1 Scroll compressors for Low GWP Heat Pumps using R290 natural refrigerant Pierre Ginies, Next Heat Pump Generation 2015
2 Danfoss Commercial Compressors Leading compressor R&D and manufacturing for commercial air conditioning, heating and refrigeration applications since 1971 Manufacturing in Europe, USA, China Leading the market in commercial inverter scrolls with prequalified drives Pioneers of Danfoss Turbocor Compressors with oil-free, magnetic bearing technology Turbocor: TR Scroll: 3-10 Hp Reciprocating: Hp Scroll: 9-40 Hp Scroll: 3-40 Hp 2 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
3 Sat Disch Temp C HFC Applications in A/C & HP R410A APPLICATION Sat Suct Temp C Roof Top Chiller Conditions for Seasonal Performances 97% of running time 3 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
4 NxtHPG Project baseline NxtHPG Project aims Heat pumps reaching higher efficiency and lower carbon footprint than current state of the art HFCs/HFOs or Sorption heat pumps Include efficient capacity modulation and the highest capabilities for combination and integration with other renewable sources in the energy systems of Buildings and Industry Hydrocarbons (HCs): air or water to water heat pumps supplying hot water at (40-50ºC) for heating applications as well as to produce sanitary hot water at 60ºC 4 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
5 NxtHPG Project baseline Heat pump application Case 1 NxtHPG051 + Inverter Case 2&3 NxtHPG038 Note 1 Case 1 & 2 should be suitable for reversible application. 2 Case 3 will use R290 5 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015

8 ηis Compression process efficiency improvement: Intermediate Discharge Valve Description: Mechanical valve that adapts the motor effort to the pressure conditions in the system to improve part-load efficiency of air conditioning systems Main Benefits Energy savings in part-load conditions Applied cost savings Lower starting load / stress on mechanical parts Gas discharge High Low Pressure Ratio: IDV closes opens Gas discharge Pressure ratio 8 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
9 Compression process efficiency improvement: High Pressure Ratio Conditions P cond > BIPR*P evap P P cond BIPR*P evap Real compression curve Ideal compression curve Backflow effect: since the gas goes back into the last compression chamber, the gas mass to be compressed increases as well as the pressure.

11 Compressor performance testing Note Hardware: Use secondary fluid HC lab 30kW calorimeter and large single fluid calorimeter >100kW Adapted to HC lab safety requirement Calorimeter #12 on HC labs 11 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
12 Performance measurement: NxtHPG Hz IDV performance improvement delta EER [W/W] and(delta [% ratio]) 12 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
13 Compression process efficiency improvement: extra IDV Benefits Danfoss Intermediate Discharge Valves reduce the compression mechanism torque reduce line amps during starting transient period allow to start at higher Saturated Suction Temperature 14 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
14 Compressor lubricant selection R290 is very soluble in classic lubricants We investigated in the past: MO POE AKB Experience (rule of thumb) use two viscosity higher grades Based on Low HC soluble POE and PAG materials. Today we will focus on: Compressor reliability R290 solubility on oil compressor sump for reduced SH conditions 15 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
15 Compressors reliability testing Discharge check valve Fixed scroll Discharge port Oldham coupling Upper bearing & shaft Orbiting scroll Orbiting scroll bearing and thrust bearing Electrical motor Lower bearing and oil pump 16 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
16 Compressors reliability testing Setting the life test conditions Based on existing experience & knowledge We use 4 modes LFT for large scrolls Bearing improvement done for flooded conditions 17 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
17 Refrigerant Solubility % in Compressor Oil Sump: steady state SST 10 C Xr[%] versus SH [K] Viscosity [cst] versus SH [K] 18 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
18 R290 Dynamic Solubility tests done Principle: Run the compressor in required conditions Various suction gas super heat One or two saturated condensing temperatures In steady state conditions, sampled lubricant from oil sump and measured the R290 % solubilized in lubricant oil sump 19 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
19 Refrigerant % in oil sump 20 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
20 Conclusions NxtHPG scrolls are based on existing HFC platform IDV integration on these R290 scrolls compressor brings: Better performances at lower pressure ratio running conditions Same compressor can be used in a wider pressure ratio applications range Improved reliability by lower mechanical load during pull down and/or pull up situations Allows to enlarge application range in higher evaporating conditions Lubricants: We have developed a new low soluble lubricant for Hydro Carbons operating in low SH conditions We are investigating the application of low miscibility lubricants Compressor design has been adjusted to keep the high reliability level 21 Commercial Compressors Pierre Ginies, Next Heat Pump Generation 2015
