Development of heat transfer coefficient correlation for minichannel condenser
Publication details: Prayagraj Pushpa Publishing House 2023Edition: Vol.33, JunDescription: 29-40pSubject(s): Online resources: In: JP journal of heat and mass transferSummary: Vapour compression refrigeration (VCR) system was designed, developed, and fabricated for testing alternative refrigerants such as R152a, R600a, R290 and mixture of R290/R600a (50/50% by mass) over presently used R134a with aluminium minichannel condenser. Heater bank was provided for controlling condensation and evaporator temperature along with sub-cooling and superheating temperature by using PID controllers. All the refrigerants are tested for condensation temperature ranging from 40°C to 55°C while evaporation temperature ranges from –15°C to 15°C. Refrigerant charge was reduced 50% with the minichannel condenser over the conventional condenser. Two phase condensation heat transfer coefficient correlation was developed from the experimental data points within ±15% with existing correlations.| Item type | Current library | Status | Barcode | |
