Abstract

This report is about Heat Recovery Process in Design and Development of Integrating Hot Water Dispenser with Portable Air Conditioner by using Peltier effects. The prototype used a heat transfer method to increase hot water temperature in the storage tank and a process of heat waste recovery undergoes to improve the thermal efficiencies equally for both sides of the Peltier effects. The current system capable to distribute cooling air from cold side Peltier at lowest 5°C and gain hot water out from the Aluminium storage tank at the highest temperature which is 83°C. The process of heating the water in storage tanks is also assisted by the use of heat Aluminium foil and black rubber foam insulation so that heat is not released to the surrounding. By combining multiple works with portable equipment concept, this research has found a solution for a better green energy safety in creating a prototype for the needs. For more, this research has differentiated between two types of the material tank; tin tank and Aluminium tank with and without insulation. The results prove that the higher thermal conductivity will produce higher heat transfer from one surface to another surface per unit area. Hence, the thermal efficiencies are 99.80%. This means that 99.80% of energy has been recovered to the hot water dispenser. Somehow, the heat loss still happen in a small amount which is below than 0.20% or lesser.
