Abstract

Energy is the most important issue in real life application for almost activity that related to work and efficiency. Improper energy consumption may increase the cost and that situation need to be improved for better energy awareness among the community. Currently, air conditioning system can be classified as important thing for certain reasons such as comfortability, filtration, and protection for specific devices or products. This air conditioning system requires high amount of energy for the operation especially for a long duration based on certain system. Energy required for air conditioning system can be extracted from natural solar energy. Absorption air conditioning system was chosen for this solar energy extraction with certain improvement at certain parts of the system. A solar collector has been built with evacuated tube, u-tube heat pipe design and dimple heat tube to increase the efficiency of the solar collector. This solar heat collector mainly focusing on absorption system with certain criteria that can improve the efficiency. Input and output temperature from this solar heat collector were an important parameter for thermal analysis. An evacuated tube located in the solar collector was designed with different heat pipe connection with other evacuated tube to get a better performance. The heat pipe in the evacuated tube also has a unique dimple design that allowed heat transfer process to occur with higher efficiency from the normal heat pipe. Then, a temperature test was conducted to determine suitable operation temperature in absorption system based on real absorption trainer module temperature. As the result, this solar heat collector managed to obtain final temperature about 69.3°C compared to trainer absorption module which was 131°C. This situation may happen because of lack of solar heat collector, insulation loss and material loss. As conclusion, a set of solar heat collector with evacuated tube, dimple heat pipe and u-tube design were developed with better thermal efficiency by 1.4 % compared to previous research.
