| Abstract | ||
| Capillary tubes are widely used in refrigerating and air conditioning units. It has no moving part however, a capillary tube is less expensive and generally performs nearly as well. In this work, the effect of capillary tube numbers on air conditioning system performance is studied for refrigerant R22. The study was adopted with the five capillary tubes at same diameter of 2.2 mm and length of 0.6 m. The experimental work shows that, the air conditioning operates with three capillary tubes gives highest COP from other of the same diameter with 14% increasing from base case of two capillary tubes, where the performance of the air conditioning that operates with one capillary tube gives the lowest COP from other. | ||
