This research paper presents the experimental performance of a window air conditioner using alternative refrigerants (R-22 and R-410A) with different configurations of capillary tube. Three capillary tubes with different length and inner diameter were selected as test sections. The capillary tube lengths were 889mm, 559mm, and 508 mm.The air-conditioner was a 1 TR unit designed for R-22 and R410A. The performance of the air-conditioner with R-410A was compared with the baseline performance with R-22.The performance parameters considered are cooling capacity, coefficient of performance, energy consumption, and compressor work. Test results shows that(1)For R-22, the COP of Capillary tube 889mm was 32% efficient than capillary 559mm and 40% efficient than capillary 508mm for 39°C outdoor temperature (2) For R-410A, the COP of Capillary 889mm was 38% efficient than capillary 559mm and 47% efficient than capillary 508mm for 39°C outdoor temperature.
