Thermal design of heat exchanger for a swimming pool

This paper tells about what is a heat exchanger made of in terms of thermal analysis and the important tools and factors which play vital role in designing them through the help of concepts learnt from heat transfer and fluid mechanics. The main objective of this paper is to design a reliable, economical heat exchanging system for different applications by selecting specific material which has a good thermal conductivity or convectivity property, designing profiles with desirable cross sectional areas to maximise the heating process. Almost all of contents and the analysis of the paper are based on the literatures available on the related subject and disciplines and a number of scientific rules together with heat transfer theories and facts have been incorporated abundantly. As the overall size of the heat exchanger is an important factor, the analysis has presented the steps and procedures needed to determine this variable and the cost aspects, which is also one of the most important tool has been discussed with the help of material selection and the economical perspective of popular materials. Ultimately the optimum overall heat transfer coefficient has been predetermined based on the requirements of amount of heat energy to be transferred by considering the other useful factors like Area of the heat exchanger, length of the heat exchanger tubes and the type of economic material. And it is found that the overall heat transfer coefficient can be maximised or minimised depending on the design and configuration of the whole system and can serve as a measure of the heat exchanging system
