| Abstract: | As a promising candidate to replace refrigerant R22,evaporative characteristics of the near-azeotropic refrigerant R410A is investigated in the evaporator of a vapor compression air-conditioning system.In the experiments,heat transfer coefficient with different geometry of micro-fin tubes was measured and compared with that of R22 for the same set-up.The overall heat transfer coefficient of the evaporation was evaluated against different flow rate of the refrigerant and air.The results show that the refrige... |
