Experimental Study on Performance of Condenser of Two Different Types Used in Window Air Conditioner

In this study, two heat exchangers were used as condensers in the same air-conditioning system, one with round tubes and the other with flat micro channel tubes. The window air conditioning systems was designed for R-22 and its alternative R-410A, with the micro channel and round tube condensers were constructed and investigated between the atmospheric temperatures 35?C to 41?C. This work presents the difference measured in the performance for both condensers. The performance of the air conditioner with R- 410A was compared with the baseline performance with R-22.The COP of micro channel condenser with R-22 is 4.52% and with R-410A is 11.3% higher than the round tube condenser. For R-22, the heat transfer in the round tube condenser is 0.75% and for R-410A is 2.39% higher than the micro channel condenser
