Abstract
Attribute to high heat transfer rate and less complexity, the Helical coil sub-cooled condenser (HCSCC) can provide the most innovative and unique application for the air conditioning system. In the case of automobiles, reduction in air-conditioning load may diminish the vehicular emission, and power consumption as the air-conditioning load is the most power-consuming components after the engine load. Moreover, to solve the problem, we focus on the helical type heat exchanger. It may play a vital role in reducing the weight and increase the performance of the small engine because of the compact structure and lighter weight. The compressor unit is the most vital component of the refrigeration cycle, but the condenser unit is also one of the most critical devices, and the author tried to reduce the power consumption by enhancing the performance of the condenser. The crucial point of this study is to use HCSCC, which exemplify the effect of subsequent flow generation inside the fluid, and it is known as the Dean's effect. This effect leads to the heterogenous temperature distribution along the square cross-sectional channel of the HCSCC. Experimentally, two different square cross-section of HCSCC has been analyzed and then compared with CFD investigation. During the analysis, various Dean numbers were evaluated at different flow rates of refrigerant as well as the varying cross-sectional area of the channel. From the result of the study, it is found that the Dean number plays a significant role in enhancing the heat transfer coefficient.
