Abstract

Cooling tube is a component that has been widely used in the application of heat transfer mechanism. This component has a good capability to transfer heat energy from a fluid flowing outside them and impart the energy into the fluid flow inside them. In air conditioning system, there will be two heat transfer devices available to regulate the cooling load inside the space. In this study, a cooling device is being taken into account for doing further research activities. One of the factors that has been identified can affect the heat transfer rate in this device is the angle of cooling tube position towards blowing direction of air. Hence, this study was carried out to investigate which angle of cooling tube position has the greatest rate of heat transfer between the fluids involved in the system. Cooling tube chosen surely is a copper tube. A simple modelling of prototype had been built includes a pathway at the both side wall of the prototype for regulating the angle of copper tube position. Three different angle of copper tube position chosen are 90°, 45° and 0° angle. Two parameter values were being taken for each angle which was outlet air and outlet water temperature. Inlet air and inlet water temperature were being kept at a fixed value. There were two types of study have been practiced which were experimental and simulation study in order to compare both results. Computational fluid dynamics (CFD) software was being used for the simulation study. The 90° angle of copper tube position had the highest value of heat transfer rate in experimental study while in the simulation study; 45° angle of copper tube position had the highest value of heat transfer rate. Based on the concept of real life situation, the results in experimental study have been decided to take into consideration as the appropriate results. In conclusion, this study had determined and verified which angle of copper tube position is the most efficient in the cooling devices.
