Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Low-GWP Alternative Refrigerants Evaluation Program (Low-GWP AREP) TEST REPORT #67 Compressor Calorimeter Test of Refrigerant ARM-25 in a R-404A Reciprocating Compressors Laurence Pérouffe Gaël Renevier Tecumseh Products Company 2 avenue Blaise Pascal 38090 Vaulx Milieu - France January 18, 2016 This report has been made available to the public as part of the author company s participation in the AHRI s Low-GWP AREP.

1. Introduction: This report covers the calorimeter testing results of refrigerant blend ARM25 (GWP100 < 150) performed by Tecumseh Products Company (Tecumseh) in the framework of the AHRI Low-GWP AREP II study. The testing was done from September to October 2015 in Tecumseh s ISO 17025 accredited Research and Development lab facility located in La Verpillière, France. The refrigerant was tested with two Tecumseh reciprocating compressors primarily approved for R-404A: FH2511Z for low back pressure commercial refrigeration type application FH4540Z for high back pressure commercial refrigeration type application No optimization, oil or hardware changes were made to account for the alternative blend. 2.

d. Description and Size of Test Loop The performance tests were done on a secondary fluid calorimeter on the suction side according method A of standard NF EN 13771-1 : 2003. A direct expansion coil serves as a primary evaporator. This evaporator is suspended in the upper part of a pressure-tight and heat-insulated vessel. A heater is located in the base of this vessel, which is charged with a secondary fluid so that the heater is well below the liquid surface. As per NF EN 13771-1 : 2003 clause 4.2.2 this calorimeter is in constant use and is subject to periodical calibration in accordance with EN ISO 9001 therefore a second concurrent test (i.e mass flow meter) is not necessary The refrigerant flow is controlled by a constant-pressure and heat-insulated expansion device located close to the calorimeter. The calorimeter is insulated and exposed to the ambient surrounding the compressor ; the secondary fluid is maintained to the same by varying the heater power in such a manner that there is no heat exchange between the calorimeter and the ambient. The suction gas is adjusted to basic test condition by injecting refrigerant collected at the condenser outlet in the suction line via an expansion device. 1 Refrigerant gas at the compressor inlet at the basic test conditions 2 Refrigerant gas at the compressor outlet 5 Refrigerant liquid at the inlet of the expansion device 6 Refrigerant gas at the outlet of the calorimeter A Compressor B Condenser C Expansion device E Heater F Calorimeter G Injection expansion device ts Temperature of the secondary fluid 4

Compressor operating conditions during test Operating map points were measured first with R404A then with ARM25 with 10K (18 F) superheat and with fixed 20 C (68 F) suction gas according NF EN 12900: 2013. 5

3. Results All compressor tests are performed at a dew point for suction and discharge pressure conditions, per AHRI Standard 540 requirements. This does not have an impact on comparing compressor performance between two or more refrigerants that do not exhibit glide. However, when refrigerants exhibit glide, it is important to note that actual systems operate closer to the mid-point condition. When comparing compressor performance of one refrigerant with glide to another refrigerant without glide, or comparing two refrigerants with significantly different glides, comparison at pressures corresponding to the midpoint of the glide rather than the dew point will yield results that are more representative of actual operation in a system. The total glide for ARM25 is 12.2K at 1 bar and 6.6K at 30 bars. R404A is near azeotropic blend with small glide less than 1K and from practical purposes can be neglected. 3.1.

5. Summary The compressor calorimeter testing of Arkema ARM25 was carried out at dew point conditions versus R- 404A. Overall the compressor capacity is within 75% to +105% of R-404A rated performance across the operating map, with extremes at high pressure ratio that should be double checked on smaller calorimeter capacity range to eliminate potential testing uncertainty. The compressor COP of ARM25 is between about 85% to +115% of R-404A across the compressor operating envelope. The discharge of ARM25 is very slightly higher than R-404A. 53
