Analysis of Bend Radius and Inlet Pipe Position on Hydronic Radiant Underfloor Heating System

Abstract

A hydronic radiant underfloor heating system (RFHS) is a type of heating system that utilizes water as the heat transfer medium to provide comfortable and efficient heating in residential and commercial buildings. The rate of energy consumption on the household level for heating and cooling is increasing annually. Meeting future heating and cooling energy demand by alternative technology like floor heating systems (FHS) is a primary concern for engineers and designers. FHS has the advantages of lower investment cost, lower energy consumption, better thermal comfort, and maintaining the desired temperature up to human height. This merit has encouraged many researchers to study FHS in terms of temperature distribution, energy analysis, thermal analysis, and control strategy throughout the world. This study aims to investigate the effect of bend radius and change in the inlet position of pipe on temperature distribution over the floor surface for different mass flow rates. The findings of this analysis will provide valuable insights into the optimal bend radius, and temperature distribution which will provide improved design
