Preliminary work comprises performing first-cut simulation by replacing R-134a in the correlated model with R-1234yf and analyzing the gap between physical test data and 1D CAE outcome. A sensitivity analysis is carried out to understand the impact of different parameters like warm-up temperatures, duct heat gain values etc. on MAC performance. Simulation results obtained by tuning these parameters are found to correlate with physical test data by > 95% accuracy. With the correlated model, this simulation methodology is deployed for another vehicle to predict the MAC performance with drop-in refrigerant. The proposed methodology will help to understand the impact of drop-in refrigerants on present HFC-based MAC systems and enable the authors to provide feasible recommendations to meet the target MAC performance for intended climatic usage conditions well before prototyping and physical validation.]]> Fri, 01 Mar 2024 08:54:19 GMT https://trid.trb.org/View/2335025 Comparative Study of Effect of Different Refrigerants (R134a, R1234yf & R407C) on Evaporator Performance https://trid.trb.org/View/2259877 Thu, 05 Oct 2023 09:32:27 GMT https://trid.trb.org/View/2259877 Improving Performance of Automotive Air Conditioning System at Vehicle Level by Optimizing the Refrigerant Quantity with Optimum Oil Quantity https://trid.trb.org/View/2259871 Tue, 03 Oct 2023 15:41:48 GMT https://trid.trb.org/View/2259871 Study of Flashing Flows Entering Evacuated Sampling Cylinders for Oil Circulation Rate Measurement in an Automotive Air Conditioning System https://trid.trb.org/View/2155614 Thu, 27 Apr 2023 17:02:16 GMT https://trid.trb.org/View/2155614 Measurements of Oil Circulation Rate using Flow-through and Evacuated Type Sampling Cylinders for an Automotive Air Conditioning System https://trid.trb.org/View/2155607 Thu, 27 Apr 2023 17:02:16 GMT https://trid.trb.org/View/2155607 Oil Droplet vs. Film Flow at Discharge and Suction after Shutdown of Automotive Compressor https://trid.trb.org/View/2155586 Wed, 19 Apr 2023 16:34:17 GMT https://trid.trb.org/View/2155586 New Low-GWP Refrigerants for Electric Vehicle Heat Pump with Superior Comprehensive Performance https://trid.trb.org/View/2155570 Wed, 19 Apr 2023 16:34:17 GMT https://trid.trb.org/View/2155570 Experimental performance comparison of R1234yf and R134a automobile air conditioning systems employing a variable capacity compressor https://trid.trb.org/View/2124848 Fri, 07 Apr 2023 13:34:30 GMT https://trid.trb.org/View/2124848 An Experimental Study for Reduction of Refrigerant Flow Induced Noise in a Passenger Vehicle https://trid.trb.org/View/2061025 Mon, 14 Nov 2022 16:29:54 GMT https://trid.trb.org/View/2061025 Enhancing AC System Performance with a Suction Line Heat Exchanger with Refrigerant HFO-1234yf https://trid.trb.org/View/1822592 Fri, 28 Oct 2022 08:43:40 GMT https://trid.trb.org/View/1822592 Natural Refrigerant on Board Marine Vessels https://trid.trb.org/View/2011955 Thu, 22 Sep 2022 14:09:03 GMT https://trid.trb.org/View/2011955 Reduction of Fuel Consumption in Air Conditioning Systems https://trid.trb.org/View/1814678 Fri, 19 Aug 2022 17:15:17 GMT https://trid.trb.org/View/1814678 Experimental Performance of a Parallel Flow Condenser with HFO-1234yf as the Working Fluid https://trid.trb.org/View/1820601 Wed, 10 Aug 2022 16:38:44 GMT https://trid.trb.org/View/1820601
