Experimental Study on the Performance of Twisted Capillary Tube
نویسنده
چکیده
A novel capillary tube has been tested and evaluated experimentally in the refrigeration cycle of window type air conditioner. Three twisted capillary tubes have been demonstrated and evaluated to show the performance of these tubes and its ability in the depressurization process seeking for short capillary tube. The effect of twist angle and the number of twisted points on the refrigeration cycle performance have been investigated and compared with the performance of original straight capillary tube. Two twist angles and two different numbers of twisting points have been considered in this study. The results showed that the twist angle has a remarkable influence on the depressurization process and condensation temperature.
