DESIGN IDEAS OF HEAT EXCHANGER IN WATER PIPELINE OUTLET FOR SINGLE HOUSEHOLD: A REVIEW

Abstract

Every single household has their own water pipeline that is very useful to fulfill their daily activities such as washing clothes, car, drinking water and for bathing. The problem they have to face is that the water they were using for daily activities is extremely hot because of outer surface of water pipeline exposed to the sunlight. This could cause an injury to the person skin, especially to the baby. It is a risk as the hot water came out unexpectedly. The objective of this project is to suggest a design for a heat exchanger to be installed at the outlet of water pipelines, specifically targeting the shower in a bathroom, for use in a single household. Essentially, heat exchangers in water pipelines are devices that enable heat transfer between two fluids of differing temperatures without allowing them to mix. The main idea usage of Heat Exchanger Water Pipeline is to cool down the hot water that flows directly from main water supply and flow out form the outlet pipeline at room temperature. Thus, this project will introduce design ideas that fulfill the user criteria and the CAD modelling of the selected design of water heat exchanger will be presented.
